 2   MainStay Capital Appreciation Fund


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.
At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/S/ CHRISTOPHER O. BLUNT


Christopher O. Blunt
President

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. From inception (5/1/86) through
12/31/94 (for Class A, first offered 1/3/95), 8/31/98 (for Class C, first
offered 9/1/98), and 12/31/03 (for Class I, first offered 1/2/04), performance
of Class A, 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 A, C, and I shares.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY CAPITAL APPRECIATION FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Rudolph C. Carryl and Edmund C. Spelman
of
MacKay Shields LLC.

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests in securities of U.S. companies with characteristics
such as participation in expanding product or service markets, increasing unit
sales volume, increasing return on investment, and better-than-average growth in
revenues and earnings when compared to stocks of the S&P 500(R) Index.(1) In
implementing this strategy, the Fund maintains a flexible approach and may
invest in various types of companies and securities. We look for companies that
we feel are ready for a rise in price or may experience acceleration in growth
of earnings, possibly as a result of changes in management, products, consumer
demand, or the economy. We may sell a security if we no longer believe it will
contribute to meeting the Fund's investment objective.

WHAT KEY FACTORS INFLUENCED THE EQUITY MARKET DURING THE REPORTING PERIOD?

Arguably the biggest factor influencing the equity market during the reporting
period was the rise in the price of crude oil, which came on the heels of a 78%
increase in crude-oil prices in the previous year. The price of crude oil rose
as high as $69.81 per barrel on August 30, 2005, before falling off somewhat.
This energy inflation was among the factors that prompted the Federal Open
Market Committee to raise the federal funds target rate at a "measured pace"
throughout the reporting period. To keep inflation in check, the FOMC raised the
federal funds target rate eight times during the reporting period, with a
25-basis-point increase on each occasion. (A basis point is one-hundredth of a
percentage point.) Since high energy prices act as a silent tax on consumers and
can weigh on consumer spending, energy costs were a continuing concern for
equity investors. On the geopolitical front, negative headlines about progress
in Iraq also weighed heavily on investors' minds throughout the reporting
period.

WHAT DECISIONS HAD THE BIGGEST INFLUENCE ON THE FUND'S PERFORMANCE?

Excluding all sales charges, all of the Fund's share classes outperformed the
Fund's primary benchmark, the Russell 1000(R) Growth Index,(2) for the 12 months
ended October 31, 2005. Effective stock selection in the health care sector had
the most dramatic positive impact on the Fund's relative performance during the
reporting period. The Fund's relative results were also helped by overweighted
positions in energy
and consumer discretionary stocks. Energy stocks benefited from a dramatic rise
in the price of oil. Consumer discretionary stocks showed solid performance,
with historically low interest rates and a strong housing environment that
strengthened consumer spending. An underweighted position in consumer staples
and effective stock selection in the sector also helped relative returns as did
a modestly overweighted position in materials and strong stock selection in the
sector. The Fund's underweighted allocation to financials had a neutral impact
on relative results. An overweighted position and poor stock selection in
industrials had a negative impact on the Fund's performance. We reduced the
Fund's industrial holdings to a market-weighted position as the year progressed.
Although the Fund was prudently underweighted in information technology through
much of 12-month reporting period, stock selection in the sector hurt the Fund's
relative performance.

WHICH INDIVIDUAL SECURITIES HAD THE GREATEST POSITIVE IMPACT ON PERFORMANCE
DURING THE REPORTING PERIOD?

Peabody Energy mines and sells low-sulphur coal, mostly to utilities. With the
dramatic rise in the price of oil, investors surmised that demand for
alternative energy sources, such as coal, nuclear energy, and natural gas, would
also increase. Apple Computer, a leading manufacturer of personal computers and
consumer electronics, advanced primarily on the sales strength of its popular
iPod MP-3 players. Caremark Rx is a pharmacy benefit management company. During
the reporting period, the company integrated a major acquisition, signed several
new contracts, expanded operating margins, and rapidly increased earnings.
Health care provider UnitedHealth Group enjoyed strong earnings because of
robust demand and strong pricing power in the health care services sector.
Shares of Genentech, a biotechnology company, advanced on strong earnings
growth, promising new products, and positive results in clinical trials.

WHICH STOCKS DETRACTED FROM PERFORMANCE?

Maxim Integrated Products, a manufacturer of linear and mixed-signal integrated
circuits, saw its stock price decline primarily because of a cautious earnings
outlook, heightened competition, and a shift to relatively lower-margin consumer
products. The world's largest on-line auction site, eBay, felt the effects of
slowing economic growth in Western European markets and softening transaction
volume in the United States. Brunswick is a manufacturer of

   Index.

recreational products, including boats, marine engines, and equipment for
fitness, bowling, and billiards. During the reporting period, Brunswick lowered
its 2005 earnings guidance and cut production in the face of rising interest
rates, higher oil prices, devastating hurricanes, and declining consumer
confidence. Harman International Industries is a supplier of high-fidelity audio
products and electronics systems for the consumer and professional markets. The
company provided disappointing earnings guidance for fiscal 2006 and faced
heightened competition in the low-end navigation-systems market. Motorcycle
manufacturer Harley-Davidson lowered production guidance for the first time in
the company's history. Sales, earnings, and profit projections were also
adjusted, which took a toll on the company's shares.

WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD?

In the spring of 2005, we sold the Fund's entire positions in several technology
stocks because our research suggested that the companies' revenue and earnings
growth might slow. The companies were Applied Materials, the industry's largest
semiconductor equipment company; KLA Tencor, a manufacturer of semiconductor
test and processing equipment; Cisco Systems, the largest provider of data
networking products; Hewlett-Packard, a diversified provider of printers and
computer products and services; and Avaya, a leading provider of corporate
telephone systems. We redeployed the proceeds from these sales in other
information technology stocks, including Corning, EMC, Apple Computer, Intel,
Texas Instruments, and Motorola.

HOW DID THE FUND'S SECTOR WEIGHTINGS CHANGE DURING THE REPORTING PERIOD?

It is important to note that the Fund's weightings are largely a residual of our
bottom-up stock-selection process and are affected by the Fund's careful sell
discipline. Because our process identified numerous attractive stocks in the
consumer discretionary sector, the Fund's exposure increased. We also increased
the Fund's exposure to the energy sector. The strong run-up in the price of oil
during the reporting period--along with the low probability that oil prices
would drop meaningfully below $50 a barrel anytime soon--led us to increase the
Fund's weighting in oil services stocks and stocks of companies that offer oil
alternatives, such as coal. We reduced the Fund's weightings in consumer
staples, industrials, and in information technology. In each case, the declines
resulted from company-specific sales rather than any overall impression about
the market or the economy. We also decreased the Fund's weighting in financials
because of rising interest rates.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

As of October 31, 2005, the Fund had overweighted positions relative to the
Russell 1000(R) Growth Index in consumer discretionary, energy, industrials, and
materials. As of the same date, the Fund was underweighted relative to the Index
in consumer staples, financials, health care, and information technology. At the
end of the reporting period, the Fund had no holdings in telecommunications

services or utilities.

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 Capital
Appreciation Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares, whose
distribution commenced on January 3, 1995, are offered at net asset value per
share plus an initial sales charge. No sales charge applies on investments of $1
million or more (and certain other qualified purchases) in Class A shares, but a
contingent deferred sales charge is imposed on certain redemptions of such
shares within one year of the date of purchase. Class B shares and Class C
shares are offered without an initial sales charge, although a declining
contingent deferred sales charge may be imposed on redemptions made within six
years of purchase of Class B shares and within one year of purchase of Class C
shares. Distribution of Class B shares and Class C shares commenced on May 1,
1986 and September 1, 1998, respectively. Class I shares are not subject to
sales charge. Distribution of Class I shares commenced on January 1, 2004. Class
A shares, Class B, Class C and Class I shares bear the same voting (except for
issues that relate solely to one class), dividend, liquidation and other rights
and conditions. Each class of shares other than Class I shares bears
distribution and/or service fee payments under a distribution plan pursuant to
Rule 12b-1 under the 1940 Act. Class I shares are not subject to a distribution
or service fee.

The Fund's investment objective is to seek long-term growth of capital. Dividend
income, if any, is an incidental consideration.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on the valuation date; such securities not
traded on the valuation date are valued at the mean of the latest quoted bid and
asked prices. Prices normally are taken from the principal market in which each
security trades. Temporary cash investments acquired over 60 days to maturity
are valued using the latest bid prices or using valuations based on a matrix
system (which considers such factors as security prices, yields, maturities, and
ratings), both as furnished by independent pricing services. Other temporary
cash investments are valued at amortized cost, which approximates market value.
Securities for which market quotations are not readily available are valued by
methods deemed in good faith by Board of Trustees to represent fair value.
Reasons for which securities may be valued in this manner include, but are not
limited to, trading for a security has been halted or suspended, a security has
been de-listed from a national exchange, or trading on a security's principal
market is temporarily closed at a time when under normal conditions it would be
open. The Fund did not hold securities at October 31, 2005, that were valued in
such manner.

(B) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (see Note 7).

(C) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are withheld at the source.

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
quarterly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

 18   MainStay Capital Appreciation Fund


The following table discloses the current year reclassifications between net
investment loss and additional paid-in-capital arising from permanent
differences; net assets at October 31, 2005, are not affected.

<Table>
<Caption>
               NET
            INVESTMENT             ADDITIONAL
               LOSS             PAID-IN CAPITAL
                           
           $13,627,331            $(13,627,331)
</Table>

(E) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on short-term securities are accreted and amortized,
respectively, on the straight line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(G) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(H) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.72% on assets up to $200 million, 0.65%
on assets from $200 million to $500 million and 0.50% on assets in excess of
$500 million. For the year ended October 31, 2005, the Manager earned fees from
the Fund in the amount of $7,512,626.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager paid the Subadvisor a monthly fee of 0.36% of the Fund's
average daily net assets on assets up to $200 million, 0.325% on assets from
$200 million to $500 million and 0.25% on assets in excess of $500 million.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from
the Fund at an annual rate of 0.25% of the average daily net assets of the
Fund's Class A shares, which is an expense of the Class A shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The Plans provide that the Class B and Class C shares of the Fund also
incur a service fee at the annual rate of 0.25% of the average daily net asset
value of the Class B or Class C shares of the Fund. Class I shares are not
subject to a distribution or service fee.

                                                    www.MAINSTAYfunds.com     19

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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 $96,156 for the year ended
October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $11,319, $912,707 and $971, respectively, for the year ended October
31, 2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund for the year ended
October 31, 2005, amounted to $4,911,409.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus the Fund only pays a
portion of the fees identified above.

(F) CAPITAL.  At October 31, 2005, New York Life and its affiliates held shares
of Class I with a net asset value of $1,061. This represents 100.0% of the Class
I shares net assets and less than one tenth of one percent of the Fund's total
net assets at October 31, 2005.

(G) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$34,116 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $159,119 for the year ended
October 31, 2005.

NOTE 4--CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, State Street Bank and Trust Company acted as custodian for
the Fund.

NOTE 5--FEDERAL INCOME TAX:

As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis
were as follows:

<Table>
<Caption>
                                            TOTAL
    ACCUMULATED CAPITAL    UNREALIZED    ACCUMULATED
     AND OTHER LOSSES     APPRECIATION      GAIN
                                   
       $(238,286,276)     $260,067,675   $21,781,399
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals.

At October 31, 2005, for federal income tax purposes, capital loss carryforwards
of $238,286,276 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.

NOTE 10--OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those arrangements and certain other levels of trading
by fund shareholders over the period from 1999 to 2003 may have had on the
funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.9 million to nine MainStay funds. The amount paid to the MainStay
Capital Appreciation Fund was $3,205,000. NYLIM has also agreed to reimburse or
pay all expenses relating to the Board of Trustees' review of this matter and
has paid substantially all of the costs associated with the other regulatory
matters described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Capital Appreciation Fund ("the
Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2005, and the related statement of operations for the year then ended, and the
statements of changes in net assets and financial highlights for each of the
years in the two-year period then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The financial highlights for the
periods presented through October 31, 2003, were audited by other auditors,
whose report dated December 18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with custodians 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, 2005,
the results of its operations for the year then ended, and the changes in its
net assets and financial highlights for each of the years in the two-year period
then ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreement, the Board of Trustees requested and received from the
Manager and Subadvisor, and reviewed, a wide variety of information. The
Trustees also requested and received information from outside data providers and
information and analysis from a third party consultant. The Trustees considered
various industry and regulatory trends in their deliberations. In considering
approval of these Agreements, and in evaluating the fairness of the compensation
to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and Subadvisor have provided historically to the Fund, and also
generally to other series of the Trust. The Manager's services to the Trust have
included investment management services, including the selection and supervision
of portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the
day-to-day management of the portfolio, providing reports to the Manager, and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. In considering the Manager's
and Subadvisor's practices relating to best execution of portfolio trades, the
Board reviewed reports of the Fund's Brokerage Committee including with respect
to analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager, the Subadvisor and certain other service
providers, as well as the Subadvisor's attention to its compliance program. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager and Subadvisor were such that, in the context of the Board's overall
review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's underperformance over several
time periods, recent change of personnel on the portfolio management team
serving the Fund, and the Subadvisor's implementation of plan intended to
improve the Fund's performance.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees considered certain benefits
expected for, and risks borne by, the Manager and its affiliates, including
benefits from soft dollar arrangements. The Trustees considered the services
provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM
Service, under other agreements, and the benefits to the Manager and its
affiliates from those relationships. The information provided to the Trustees
indicated that the profitability to the Manager and its affiliates arising
directly from those other agreements was not excessive. The Trustees
acknowledged certain benefits to the reputation of the Manager and its
affiliates, as well to that of the Trust, from their association with each
other.

The Trustees, in considering economies of scale, reviewed information showing
that the Fund, though one of the largest series of the MainStay Funds, had not
significantly increased in size during the past five years. The Trustees
discussed the extent to which, in the event the Fund were to increase in size,
economies of scale were projected by the Manager to be realized. They noted that
the Fund's contractual management fee had been reduced by the breakpoint
schedule applicable to the Fund that was intended to provide that the Fund's
shareholders would

share in benefits from economies of scale arising from the growth of Fund
assets. Acknowledging the difficulty of forecasting economies of scale, the
Trustees generally expressed an intention to monitor the Manager's profitability
and consider the application of fee breakpoints or other appropriate measures as
the Board may determine from time to time. The Trustees reviewed historical
information about changes in the Fund's expense and asset levels over time, as
well as information about certain Fund expenses that would remain fixed even as
Fund assets increase and, therefore, provide the Fund with benefits from
economies of scale as the Fund grows. The Trustees considered various
information about transfer agency expenses, including information showing that
transfer agency fees of a significant number of series of the Trust (although
not every such series or with respect to every share class of each series)
tended to be high, when aggregated and expressed as a percentage of the assets
of certain series, compared to the mutual fund industry average according to
certain studies reviewed by the Board and, therefore, adversely affected gross
expense ratios. The Board received information about potential effects on the
Manager were it to subsidize certain portions of the Trust's transfer agency
fees. The Trustees noted that a significant number of shareholders of the
Trust's series had small amounts invested in the series, and have considered
measures intended to increase average shareholder account size and/or otherwise
reduce the Trust's transfer agency fees and expenses, including steps that the
Manager has taken to encourage shareholders to consolidate or close small
accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts, that had investment objectives similar to
that of the Fund. The Trustees took into account information provided by the
Manager or Subadvisor about the relative scope of services provided to the Fund
and to those accounts or explanations about the accounts' histories. In
considering the extent of the fees received by the Manager and Subadvisor for
providing services to the Fund, the Trustees evaluated factors such as the fees
and expenses borne by other registered funds in the market pursuing strategies
generally similar to those followed by the Fund. The Trustees considered the
Fund's historical and proposed contractual and net management fees, its
anticipated expense ratio, and various components of that expense ratio, in
comparison to other funds in comparison groupings prepared by outside data
providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

 2   MainStay Diversified Income Fund


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.
At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/S/ CHRISTOPHER O. BLUNT


Christopher O. Blunt
President

THAN THEIR ORIGINAL COST. FOR CURRENT TO THE MOST RECENT MONTH-END PERFORMANCE
INFORMATION, PLEASE CALL 1-800-MAINSTAY (1-800-624-6782) OR VISIT

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 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. The fee waivers and/or expense limitations are contractual and
may be modified or terminated only with the approval of the Board of Trustees.
From inception (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.

1. The Fund compares itself to a Three-Index Composite that assumes equal
   investments in the Lehman Brothers(R) Aggregate Bond Index, the Credit Suisse
   First Boston(TM) High Yield Index, and the Citigroup Non-U.S. Dollar World
   Government Bond Index. All indices are unmanaged. The indices measure the
   performance of securities in the U.S. government and domestic
   investment-grade bond sector, the U.S. high-yield bond sector, and the
   international bond sector, respectively. Results assume that all income and
   capital gains are reinvested in the index or indices that produce them. The
   Fund's Three-Index Composite is considered to be the Fund's broad-based
   securities-market index for comparison purposes. An investment cannot be made
   directly into an index or this composite.
2. The Lehman Brothers(R) Aggregate Bond Index is an unmanaged index that
   includes the following other unmanaged Lehman Brothers(R) Indices: the
   Government Index, Corporate Index, Mortgage-Backed Securities Index and
   Asset-Backed Securities Index. To qualify for inclusion in the Lehman
   Brothers(R) Aggregate Bond Index, securities must be U.S. dollar denominated
   and investment grade and have a fixed-rate coupon, a remaining maturity of at
   least one year, and a par amount outstanding of at least $150 million.
   Results assume reinvestment of all income and capital gains. An investment
   cannot be made directly into an index.
3. Lipper Inc. is an independent fund performance monitor. Results are based on
   total returns with all dividend and capital-gain distributions reinvested.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY DIVERSIFIED INCOME FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balance or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

   (1.35% for Class A, 2.10% for Class B and Class C, and 0.99% for Class I)
   multiplied by the average account value over the period, divided by 365,
   multiplied by 184 (to reflect the one-half year period).

Questions answered by portfolio managers Donald E. Morgan and Joseph Portera of
MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 65% of its total assets in a diversified
portfolio of domestic and foreign debt or debt-related securities issued by
government and corporate issuers. The securities may be denominated in U.S. or
foreign currencies and may have fixed, variable, floating, or inverse floating
rates of interest. The Fund invests in various bond-market sectors including
U.S. government securities (which may include mortgage-related and asset backed
securities), foreign government securities and U.S. corporate and foreign
corporate debt securities. The Fund may invest in high-yield securities, if
available, in any of these sectors. Allocations across market sectors are based
on current and projected economic and market conditions. In implementing this
strategy, we seek to identify investment opportunities based on the financial
condition and competitiveness of individual companies. In making allocation and
sector decisions, we may rely on fundamental economic-cycle analysis. We may
also consider credit quality and interest-rate trends. Investments may include
bonds of established economies and emerging markets.

WHAT SIGNIFICANT FACTORS AFFECTED THE BOND MARKET DURING THE 12 MONTHS ENDED
OCTOBER 31, 2005?

The Federal Open Market Committee raised the targeted federal funds rate eight
times during the reporting period, with a 25-basis-point increase on each
occasion. This caused a sharp increase in the yields of short-term domestic
issues. Strong inflows from Asian central banks helped support prices among
longer-dated U.S. Treasurys and resulted in a substantial flattening of the
yield curve during the reporting period.

In the domestic bond market, yield spreads(1) between investment-grade corporate
bonds and U.S. Treasurys continued to contract throughout the reporting period.
The automotive sector was a notable exception, largely because of difficulties
at Ford and General Motors that led Moody's and Standard & Poor's to downgrade
their debt to high-yield (or "fallen angel") status. In the non-U.S. dollar
market, currency exposure had a negative impact because the dollar rallied
relative to most major currencies. Emerging markets remained resilient. With
credit upgrades and increased institutional-investor participation,
emerging-market spreads reached record lows relative to U.S. Treasurys. For most
of the reporting period, U.S. high-yield issues saw tight spreads but little in
the way of increased default risk. The inclusion of General Motors in the
high-yield universe added volatility.

HOW DID THE FUND PERFORM RELATIVE TO ITS PEERS DURING THE REPORTING PERIOD?

In our estimation, the Fund's relative performance was adversely affected by its
currency exposure and by a smaller weighting than peer funds in emerging-market
debt. The Fund's airline holdings took a toll on the Fund's performance in the
high-yield sector. Fortunately, the Fund had little exposure to the automotive
industry in the investment-grade portion of the Fund's portfolio.

WHAT WERE SOME OF THE MAJOR DECISIONS THAT AFFECTED THE FUND'S PERFORMANCE?

We significantly altered the Fund's overall asset allocation during the 12-month
reporting period. We substantially reduced the Fund's high-yield allocation.
Over the same period, we increased the Fund's allocation to international bonds
and its allocation to investment-grade debt. In the international-bond portion
of the Fund, we put the new money to work in emerging-market dollar debt, which
had a positive impact on the Fund's performance. Since high-yield securities
outperformed investment-grade debt during the reporting period, the allocation
shift detracted from the Fund's overall performance. Our decision to increase
currency exposure also hurt the Fund's performance because the dollar continued
to rise for most of the reporting period.


Funds that invest in bonds are subject to interest rate, credit, and inflation
risk and can lose principal when interest rates rise. Foreign securities may be
subject to greater risks than U.S. investments, including currency fluctuations,
less-liquid trading markets, greater price volatility, political and economic
instability, less publicly available information, and changes in tax or currency
laws or monetary policy. These risks are likely to be greater in emerging
markets than in developed markets. High-yield securities ("junk bonds") are
generally considered speculative because they present a greater risk of loss
than higher-quality debt securities and may be subject to greater price
volatility. The Fund may invest in derivatives, which may increase the
volatility of the Fund's net asset value and may result in a loss to the Fund.
The Fund may experience a portfolio turnover rate of over 100% and may generate
short-term capital gains which are taxable.
1. The terms "spread" and "yield spread" may refer to the difference in yield
   between a specific security or type of security and comparable U.S. Treasury
   issues. The terms may also refer to the difference in yield between two
   specific securities or types of securities at a given time.

WHAT SPECIFIC FACTORS LED YOU TO MAKE THE CHANGES IN THE FUND'S ALLOCATION?

Each allocation change had its own logic. Early in the reporting period, our
high-yield group became concerned about the tight yield spread between
high-yield bonds and U.S. Treasurys. We were also concerned about the reduced
quality of new issues in the high-yield market, which limited our source of new
high-yield investments. As a result, we began to slowly rotate out of high-yield
securities and into emerging-market and investment-grade debt. We did this by
allocating new money to emerging-market and investment-grade securities and by
making redemptions among high-yield holdings. We also increased cash in the
high-yield portion of the Fund's portfolio.

On the currency front, we concluded that the U.S. current account and budget
deficits would come under increasing stress leading to a U.S. dollar sell-off.
Early in the reporting period, we started adding exposure to the yen, the euro,
and to a lesser degree the Canadian dollar. Having seen the U.S. dollar continue
to rise against most foreign currencies, however, we recently elected to hedge
part of the Fund's yen exposure to help protect against further downside risk.

From the start of the reporting period our investment-grade group had been
underweighted in the troubled auto sector. In May we sold the Fund's position in
GMAC leaving only a small position in Ford Motor paper. As spreads continued to
widen in the auto sector, high-yield investors began to take notice. Toward the
end of the first calendar quarter of 2005, the high-yield group started to buy
General Motors, adding GMAC and GM paper starting in March.

HOW DID SPECIFIC PORTIONS OF THE FUND'S PORTFOLIO PERFORM DURING THE REPORTING
PERIOD?

Emerging-market debt was by far the Fund's best-performing asset class during
the reporting period. Non-U.S. dollar debt with unhedged currency exposure was
the worst-performing asset class. Exclusive of all fees and sales charges, the
high-yield portion of the Fund's portfolio provided a total return of 6.32%, the
international-bond portion returned 3.4%, and the domestic high-grade portion
returned 1.7%.

WERE THERE ANY SIGNIFICANT PURCHASES AND SALES DURING THE REPORTING PERIOD?

In the international portion of the Fund's portfolio, we bought Brazilian and
Mexican bonds in February and March. We took profits in Russian 30-year debt in
September. Significant purchases in the high-yield portion of the Fund's
portfolio included several GMAC issues during the second and third calendar
quarters of 2005 and securities issued by Qwest in August 2005.

HOW DID THE FUND PERFORM RELATIVE TO ITS BENCHMARK?

The Fund compares itself to a Three-Index Composite that assumes equal
investments in the Lehman Brothers(R) Aggregate Bond Index, the Credit Suisse
First Boston(TM) High Yield Index, and the Citigroup Non-U.S. Dollar World
Government Bond Index.(2) The Fund's performance relative to this benchmark was
positive because the Fund's overall currency exposure was considerably less than
the 33% implied by the non-currency-hedged Citigroup Non-U.S. Dollar World
Government Bond Index. At the end of the reporting period, less than 15% of the
Fund's assets carried currency exposure. Emerging-market debt, which contributed
to the Fund's positive performance, is not significantly reflected in any of the
three indices in the benchmark.

Exclusive of all fees and sales charges, the high-yield portion of the Fund's
portfolio had strong nominal performance and outperformed the Credit Suisse
First Boston(TM) High Yield Index. Although on the same basis the
investment-grade portion of the Fund's portfolio outperformed the Lehman
Brothers(R) Aggregate Index, the nominal return was lower than that in the
high-yield and international portions of the Fund's portfolio.

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
Diversified Income Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Distribution of Class A shares
and Class B shares commenced on February 28, 1997. Class C shares and Class I
shares were initially offered on September 1, 1998 and January 2, 2004,
respectively. Class A shares are offered at net asset value per share plus an
initial sales charge. No sales charge applies on investments of $1 million or
more (and certain other qualified purchases) in Class A shares, but a contingent
deferred sales charge is imposed on certain redemptions of such shares within
one year of the date of purchase. Class B shares and Class C shares are offered
without an initial sales charge, although a declining contingent deferred sales
charge may be imposed on redemptions made within six years of purchase of Class
B shares and within one year of purchase of Class C shares. Class I shares are
not subject to sales charge. Class A, Class B, Class C and Class I shares bear
the same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights and conditions. Each class of shares other than
Class I shares bears distribution and/or service fee payments under a
distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares are
not subject to a distribution or service fee.

The Fund's investment objective is to provide current income and competitive
overall return by investing primarily in domestic and foreign debt securities.

The Fund invests in high yield securities (sometimes called "junk bonds"), which
are generally considered speculative because they present a greater risk of
loss, including default, than higher quality debt securities. These securities
pay a premium--a high interest rate or yield--because of the increased risk of
loss. These securities can also be subject to greater price volatility.

The Fund also invests in foreign securities which carry certain risks that are
in addition to the usual risks inherent in domestic instruments. These risks
include those resulting from currency fluctuations, future adverse political and
economic developments and possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. These risks are likely to be
greater in emerging markets than in developed markets. The ability of issuers of
debt securities held by the Fund to meet their obligations may be affected by
economic and political developments in a specific country, industry or region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or brokers selected by the Fund's Manager, whose prices reflect
broker/dealer supplied valuations and electronic data processing techniques, if
such prices are deemed by the Fund's Manager to be representative of market
values, at the regular close of business of the New York Stock Exchange. Equity
securities are valued at the latest quoted sales prices as of the close of
trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the
valuation date; such securities not traded on the valuation date are valued at
the mean of the latest quoted bid and asked prices. Prices normally are taken
from the principal market in which each security trades. Options contracts are
valued at the last posted settlement price on the market where such options are
principally traded. Foreign currency forward contracts are valued at their fair
market values determined on the basis of the mean between the last current bid
and asked prices based on dealer or exchange quotations. Temporary cash
investments acquired over 60 days to maturity are valued using the latest bid
prices or using valuations based on a matrix system (which considers such
factors as security prices, yields, maturities, and ratings), both as furnished
by independent pricing services. Other temporary cash investments are valued at
amortized cost, which approximates market value. Securities for which market
quotations are not readily available are valued by methods deemed in good faith
by Board of Trustees to represent fair value. Reasons for which securities may
be valued in this manner include, but are not limited to, trading for a security
has been halted or suspended, a security has been de-listed from a national
exchange, or trading on a security's principal market is temporarily closed at a
time when under normal conditions it would be open. At October 31, 2005, the
Fund held securities with a value of $166,521 that were valued in such manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor conclude that such events may have effected the accuracy
of the last price reported on the local foreign market, the Manager or
Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of
the local price to reflect the

 30   MainStay Diversified Income Fund


impact on the price of such securities as a result of such events.

(B) FOREIGN CURRENCY FORWARD CONTRACTS.  A foreign currency forward contract is
an agreement to buy or sell currencies of different countries on a specified
future date at a specified rate. During the period the forward contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking to market" such contract on a daily basis to reflect the
market value of the contract at the end of each day's trading. When the forward
contract is closed, the Fund records a realized gain or loss equal to the
difference between the proceeds from (or cost of) the closing transaction and
the Fund's basis in the contract. The Fund enters into foreign currency forward
contracts primarily to hedge its foreign currency denominated investments and
receivables and payables against adverse movements in future foreign exchange
rates or to try to enhance the Fund's returns.

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
period end to credit loss in the event of a counterparty's failure to perform
its obligations. (See Note 7)

(C) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its portfolio securities or foreign currencies. Premiums are received
and are recorded as liabilities. The liabilities are subsequently adjusted and
unrealized appreciation or depreciation is recorded to reflect the current value
of the options written. Premiums received from writing options which expire are
treated as realized gains. Premiums received from writing options which are
exercised or are cancelled in closing purchase transactions are added to the
proceeds or netted against the amount paid on the transaction to determine the
realized gain or loss. By writing a covered call option, in exchange for the
premium, the Fund foregoes the opportunity for capital appreciation above the
exercise price should the market price of the underlying security or foreign
currency increase but, as long as the obligation as a writer continues, have
retained the risk of loss should the price of the underlying security decline.
By writing a covered put option, the Fund, in exchange for the premium, accepts
the risk of decline in the market value of the underlying security or foreign
currency below the exercise price. After writing a put option, the Fund may
incur a loss equal to the difference between the exercise price of the option
and the sum of the market value of the underlying security plus the premium
received from the sale of the option. A call option may be covered by the call
writer's owning the underlying security throughout the option period. A call
option may also be covered by the call writer's maintaining liquid assets valued
at greater than the exercise price of the call written, in a segregated account
with its custodian.

The Fund may purchase call and put options on its portfolio securities. The Fund
may purchase call options to protect against an increase in the price of the
security it anticipates purchasing. The Fund may purchase put options on its
securities to protect against a decline in the value of the security or to close
out covered written put positions. The Fund may also purchase options to seek to
enhance returns. Risks may arise from an imperfect correlation between the
change in market value of the securities held by the Fund and the prices of
options relating to the securities purchased or sold by the Fund and from the
possible lack of a liquid secondary market for an option. The maximum exposure
to loss for any purchased option is limited to the premium initially paid for
the option.

(D) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See Note 7).

(E) LOAN ASSIGNMENTS, PARTICIPATIONS AND COMMITMENTS.  The Fund invests in loan
assignments and loan participations. Loan assignments and participations are
agreements to make money available (a "commitment") to a borrower in a specified
amount, at a specified rate and within a specified time. Such loan assignments
and participations are typically senior, secured and collateralized in nature.
The Fund records an investment when the borrower withdraws money and records
interest as earned. These loans pay interest at rates which are periodically
reset by reference to a base lending rate plus a spread. These base lending
rates are generally the prime rate offered by a designated U.S. bank or London
InterBank Offered Rate (LIBOR).

The loans in which the Fund invests are generally readily marketable, but may be
subject to some restrictions on resale. The Fund may be contractually obligated
to receive approval from the agent bank and/or borrower prior to the sale of
these investments.

The Fund assumes the credit risk of the Borrower, the Selling Participant and
any other persons interpositioned

                                                    www.MAINSTAYfunds.com     31

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

between the Fund and the Borrower ("Intermediate Participants"). In the event
that the Borrower, Selling Participant or Intermediate Participants becomes
insolvent or enters into bankruptcy, the Fund may incur certain costs and delays
in realizing payment, or may suffer a loss of principal and/or interest.

Unfunded commitments represent the remaining obligation of the Fund to the
Borrower. At any point in time, up to the maturity date of the issue, the
Borrower may demand the unfunded portion. These unfunded amounts are recorded in
memorandum accounts.

(F) MORTGAGE DOLLAR ROLLS.  The Fund enters into mortgage dollar roll ("MDR")
transactions in which it sells mortgage-backed securities ("MBS") from its
portfolio to a counterparty from whom it simultaneously agrees to buy a similar
security on a delayed delivery basis. The MDR transactions of the Fund are
classified as purchase and sale transactions. The securities sold in connection
with the MDRs are removed from the portfolio and a realized gain or loss is
recognized. The securities the Fund has agreed to acquire are included at market
value in the portfolio of investments and liabilities for such purchase
commitments are included as payables for investments purchased. During the roll
period, a Fund forgoes principal and interest on the securities. A Fund is
compensated by the difference between the current sales price and the forward
price for the future purpose as well as by the earnings on the cash proceeds of
the initial sale. MDRs may be renewed without physical delivery of the
securities subject to the contract. The Fund maintains a segregated account with
its custodian containing securities from its portfolio having a value not less
than the repurchase price, including accrued interest. MDR transactions involve
certain risks, including the risk that the MBS returned to the Fund at the end
of the roll, while substantially similar, could be inferior to what was
initially sold to the counterparty.

(G) RESTRICTED SECURITIES.  A restricted security is a security which has been
purchased through a private offering and cannot be resold to the general public
without prior registration under the Securities Act of 1933 (the "1933 Act").
The Fund does not have the right to demand that such securities be registered.
Disposal of these securities may involve time-consuming negotiations and expense
and prompt sale at an acceptable price may be difficult. (See Note 7)

(H) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are withheld at the source.

(I) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
monthly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

The following table discloses the current year reclassifications between
accumulated distributions in excess of net investment income and accumulated net
realized loss on investments arising from permanent differences; net assets at
October 31, 2005, are not affected.

The reclassifications for the Fund are primarily due to premium amortization
adjustments, straddles, paydown and foreign currency gain (loss).


(J) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on securities, other than short-term securities,
purchased for the Fund are accreted and amortized, respectively, on the constant
yield method over the life of the respective securities or, in the case of a
callable security, over the period to the first date of call. Discounts and
premiums on short-term securities are accreted and amortized, respectively, on
the straight line method. Income from payment-in-kind securities is recorded
daily based on the effective interest method of accrual.

The investment income and realized and unrealized gains and losses on
investments of the Fund are allocated to separate classes of shares based upon
their relative net assets on the date the income is earned or realized and
unrealized gains and losses are incurred.

(K) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at
the mean between the buying and selling rates last quoted by any major U.S. bank
at the following dates:


(i)  market value of investment securities, other assets and liabilities--at the
     valuation date,

(ii) purchases and sales of investment securities, income and expenses--at the
     date of such transactions.

The assets and liabilities are presented at the exchange rates and market values
at the close of the period. The realized and unrealized changes in net assets
arising from fluctuations in exchange rates and market prices of securities are
not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments, are reflected in
unrealized foreign exchange gains or losses at period end exchange rates.

(L) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(M) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(N) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.60% on assets up to $500 million and
0.55% on assets in excess of $500 million. Effective August 1, 2005, the Manager
has entered into a written expense limitation agreement, under which the Manager
has agreed to reimburse the expenses of the Fund so that the total operating
expenses (excluding taxes, interest, litigation, extraordinary expenses, and
brokerage and other transaction expenses relating to the purchase or sale of
portfolio investments) do not exceed, on an annualized basis, 1.30% of the
average daily net assets of the Class A shares. An equivalent reimbursement, in
an equal amount of basis points, will be applied to the other share classes. The
Manager, within three years of incurring such expenses, may recoup the amount of
any management fee waiver or expense reimbursement from the Fund pursuant to
this agreement if such recoupment does not cause the Fund to exceed the expense
limitations. At October 31, 2005, the Fund had $19,479 of recoupment available.
This amount is available until October 31, 2008. This expense limitation may be
modified or terminated only with the approval of the Board of Trustees. Prior to
August 1, 2005 and after December 1, 2004, NYLIM voluntarily agreed to reimburse
the expenses of the Fund so that total annual fund operating expenses do not
exceed on an annualized basis 1.35% of the average daily net assets of the Class
A shares, and such that there would be an equivalent reduction for the other
classes of shares. For the year ended October 31, 2005, the Manager earned fees
from the Fund in the amount of $791,423, and waived its fee and/or reimbursed
expenses in the amount of $87,293.

                                                    www.MAINSTAYfunds.com     33

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager paid the Subadvisor a monthly fee of 0.30% of the Fund's
average daily net assets. To the extent that the Manager has agreed to reimburse
expenses of the Fund, the Subadvisor has voluntary agreed to do so
proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from
the Fund at an annual rate of 0.25% of the average daily net assets of the
Fund's Class A shares, which is an expense of the Class A shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The Plans provide that the Class B and Class C shares of the Fund also
incur a service fee at the annual rate of 0.25% of the average daily net asset
value of the Class B or Class C shares of the Fund. Class I shares are not
subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $31,598 for the year ended
October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $284, $69,918 and $3,573, respectively, for the year ended October 31,
2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund for the year ended
October 31, 2005, amounted to $373,528.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus the Fund only pays a
portion of the fees identified above.

(F) CAPITAL.  At October 31, 2005 NYLIFE Distributors held shares of Class B
with a value of $7,584,384 which represents 10.6% of Class B net assets and 6.0%
of the total Fund's net assets at October 31, 2005.

(G) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$3,416 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $39,857 for the year ended
October 31, 2005.

NOTE 4--CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, The Bank of New York acted as custodian for the Fund.

NOTE 5--FEDERAL INCOME TAX:

As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis
were as follows:

 ----------------------------------------------------------------------

 34   MainStay Diversified Income Fund


The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale loss deferrals, deferral of losses on foreign
currency forward contracts for tax purposes and interest on defaulted
securities.

At October 31, 2005, for federal income tax purposes, capital loss carryforwards
of $3,840,926 were available as shown in the table below, to the extent provided
by the regulations to offset future realized gains of the Fund through the years
indicated. To the extent that these loss carryforwards are used to offset future
capital gains, it is probable that the capital gains so offset will not be
distributed to shareholders.

NOTE 10--OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completely responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those agreements and certain other levels of trading by
fund shareholders over the period from 1999 to 2003 may have had on the Funds.
As a result of this review, in December 2005, NYLIM made payments totaling $5.9
million to nine MainStay funds. No payment was made with respect to the MainStay
Diversified Income Fund. NYLIM has also agreed to reimburse or pay all expenses
relating to the Board of Trustees' review of this matter and has paid
substantially all of the costs associated with the other regulatory matters
described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

 38   MainStay Diversified Income Fund


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Diversified Income Fund ("the
Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2005, and the related statement of operations for the year then ended, and the
statements of changes in net assets and financial highlights for each of the
years in the two-year period then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The financial highlights for the
periods presented through October 31, 2003, were audited by other auditors,
whose report dated December 18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Diversified Income Fund of The MainStay Funds as of October 31, 2005,
the results of its operations for the year then ended, and the changes in its
net assets and financial highlights for each of the years in the two-year period
then ended, in conformity with U.S. generally accepted accounting principles.

to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and Subadvisor have provided historically to the Fund, and also
generally to other series of the Trust. The Manager's services to the Trust have
included investment management services, including the selection and supervision
of portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the
day-to-day management of the portfolio, providing reports to the Manager, and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. In considering the Manager's
and Subadvisor's practices relating to best execution of portfolio trades, the
Board reviewed reports of the Fund's Brokerage Committee including with respect
to analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager, the Subadvisor and certain other service
providers, as well as the Subadvisor's attention to its compliance program. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager and Subadvisor were such that, in the context of the Board's overall
review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in managements presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's mid-range performance when
compared over several time periods with funds concluded by Trustees to be peers
of the Fund.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees noted the Manager's
agreement to limit the Fund's net expenses to a certain level with respect to
the Fund, with the expectation that the Manager intended, over time, to
implement measures designed to reduce the Trust's transfer agency fees. The
Trustees considered certain benefits expected for, and risks borne by, the
Manager and its affiliates, including benefits from soft dollar arrangements.
The Trustees considered the services provided to the Fund by affiliates of the
Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the
benefits to the Manager and its affiliates from those relationships. The
information provided to the Trustees indicated that the profitability to the
Manager and its affiliates arising directly from those other agreements was not
excessive. The Trustees acknowledged certain benefits to the reputation of the
Manager and its affiliates, as well to that of the Trust, from their association
with each other.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund grows, or as the Trust grows overall,
noting in particular the Manager's plans for marketing and distributing shares
of various series of the Trust. They noted the Manager's willingness to
implement contractual breakpoints, and that the contractual breakpoints in place

                                                    www.MAINSTAYfunds.com     43


for the management fee were intended to provide that the Fund's shareholders
would share in benefits from economies of scale arising from the growth of Fund
assets. The Trustees acknowledged that the Fund had not yet reached the asset
level at which breakpoints would reduce the contractual management fee to which
the Fund is subject. Acknowledging the difficulty of forecasting economies of
scale, the Trustees generally expressed an intention to monitor the Manager's
profitability and consider the application of fee breakpoints or other
appropriate measures as the Board may determine from time to time. The Trustees
reviewed historical information about changes in the Fund's expense and asset
levels over time, as well as information about certain Fund expenses that would
remain fixed even as Fund assets increase and, therefore, provide the Fund with
benefits from economies of scale as the Fund grows. The Trustees noted that, to
the extent the Fund's gross expenses currently are higher than its net expenses,
economies of scale achieved through an increase in the Fund's assets might not
directly benefit the Fund through lower net expenses. The Trustees considered
various information about transfer agency expenses, including information
showing that transfer agency fees of the Fund and a significant number of series
of the Trust (although not every such series or with respect to every share
class of each series) tended to be high, when aggregated and expressed as a
percentage of the assets of certain series, compared to the mutual fund industry
average according to certain studies reviewed by the Board and, therefore,
adversely affected gross expense ratios. The Board received information about
potential effects on the Manager were it to subsidize certain portions of the
Trust's transfer agency fees. The Trustees noted that a significant number of
shareholders of the Trust's series had small amounts invested in the series, and
have considered measures intended to increase average shareholder account size
and/or otherwise reduce the Trust's transfer agency fees and expenses, including
steps that the Manager has taken to encourage shareholders to consolidate or
close small accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts, that had investment objectives similar to
that of the Fund. The Trustees took into account information provided by the
Manager or Subadvisor about the relative scope of services provided to the Fund
and to those accounts or explanations about the accounts' histories. In
considering the extent of the fees received by the Manager and Subadvisor for
providing services to the Fund, the Trustees evaluated factors such as the fees
and expenses borne by other registered funds in the market pursuing strategies
generally similar to those followed by the Fund. The Trustees considered the
Fund's historical and proposed contractual and net management fees, its
anticipated gross and net expense ratios, and various components of that expense
ratio, in comparison to other funds in comparison groupings prepared by outside
data providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

 2   MainStay Mid Cap Value Fund


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.
At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/S/ CHRISTOPHER O. BLUNT


Christopher O. Blunt
President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee, and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Class R1 shares are sold with
no initial sales charge or CDSC and have no annual 12b-1 fee. Class R2 shares
are sold with no initial sales charge or CDSC and have an annual 12b-1 fee of
..25%. Class R1 and R2 shares are available only through corporate-sponsored
retirement programs, which include certain minimum program requirements.
Performance figures reflect certain fee waivers and/or expense limitations,
without which total returns may have been lower. The fee waivers and/or expense
limitations are contractual and may be modified or terminated only with the
approval of the Board of Trustees. 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 (6/1/98) through 12/31/03, performance for Class I, R1,
and R2 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,
R1, and R2 shares.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY MID CAP VALUE FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested, to estimate the expenses that
you paid during the six-months ended October 31, 2005. Simply divide your
account value by $1,000 (for example, an $8,600 account value divided by $1,000
= 8.6), then multiply the result by the number under the heading entitled
"Expenses Paid During Period" to estimate the expenses you paid on your account
during this period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balance or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Richard A. Rosen and Mark T. Spellman
of MacKay Shields LLC.

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in common and preferred
stock of companies with market capitalizations that, at the time of investment,
are similar to those of companies in the Russell Midcap(R) Value Index.(1) The
Fund normally invests at least 80% of its assets in securities that we believe
are undervalued when purchased, pay cash dividends, and are listed on a national
securities exchange or traded in the over-the-counter market. In implementing
this strategy, we seek to identify investment opportunities based on the
financial condition and competitiveness of individual companies. In particular,
we look for equities that we deem to be undervalued based on a number of
factors, including relative valuation, prospects for future earnings growth,
ability to grow dividends, and corporate management.

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED
OCTOBER 31, 2005?

During the 12-month reporting period, stocks generally advanced, despite
political events and energy price fluctuations. Value stocks outperformed growth
stocks at all capitalization levels. Crude-oil prices rallied to $69.81 per
barrel and natural gas prices broke $14 per million Btu before backing off
somewhat. Major hurricanes affected supply-and-demand dynamics by damaging oil
rigs and petrochemical plants. The price of gasoline rose to more than $3 a
gallon, which threatened to slow consumer spending. Although hurricane-related
stocks--including retailers, insurers, and companies on the Gulf Coast--were
weakened, the long-term economic impact appeared to be manageable.

The Federal Open Market Committee raised the targeted federal funds rate eight
times during the 12-month reporting period, with a 25-basis-point increase on
each occasion. (A basis point is one-hundredth of a percentage point.) On
October 31, 2005, the federal funds target rate stood at 3.75%. During the
reporting period, the yield curve flattened to reflect concern over a potential
recession. Yet the most recent gross-domestic-product data suggests that the
overall economy has remained resilient.

WHAT WERE SOME OF THE FUND'S STRONG PERFORMERS DURING THE REPORTING PERIOD?

The top-five positive contributors to the Fund during the reporting period were
all from the contract drilling segment of the energy sector. Transocean Energy,
ENSCO International, GlobalSantaFe, Rowan, and Pride International each
benefited from higher oil and natural gas prices. These companies also benefited
from the perception that day rates may continue to rise if damage to the Gulf of
Mexico's drilling infrastructure tightens drilling-rig supply. Earnings results
at these companies came in better than expected throughout the reporting period,
which raised expectations and drove stock prices higher.

WHICH STOCKS DETRACTED FROM THE FUND'S RESULTS?

Three stocks in the paper industry hurt the Fund's performance during the
reporting period. We purchased shares of Canadian newsprint manufacturer
Abitibi-Consolidated in March 2005, and the company's shares slid through
October because of higher energy costs and weaker-than-expected demand. The Fund
continued to hold the company's shares, how-
ever, because we felt they were attractively valued. The company has begun to
concentrate on share-
holder value by monetizing some noncore operations and cutting excess capacity.

Paper company Bowater was plagued by higher feed-stock costs, sluggish demand,
product substitution, and excess capacity. We reduced the Fund's position in
this stock because we felt that conditions were not likely to get materially
better in the foreseeable future.

Linerboard manufacturer Smurfit-Stone Container faced trends similar to those at
Bowater and Abitibi-Consolidated. The company also had difficulty passing
through higher costs. We reduced the Fund's position in Smurfit-Stone Container
near the end of the reporting period.

We initiated a Fund position in Molson Coors Brewing in March 2005. After the
share price declined and recent merger synergies were slow to materialize, we
decided to eliminate the position from the portfolio in July 2005.


Mid-capitalization companies are generally less established and their stocks may
be more volatile and less liquid than the securities of large companies. The
Fund may experience a portfolio turnover rate of over 100% and may generate
short-term capital gains which are taxable.

   Index.

 8   MainStay Mid Cap Value Fund


HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

As of October 31, 2005, the Fund held overweighted positions relative to the
Russell Midcap(R) Value Index in energy, materials, and industrials. On the same
date, the Fund was underweighted relative to the Index in financials, consumer
discretionary, utilities, information technology, and health care.

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 Mid Cap
Value Fund (the "Fund"), a diversified fund.

The Fund currently offers six classes of shares, Class A shares, Class B shares,
Class C shares, Class I shares, Class R1 shares and Class R2 shares.
Distribution of Class A shares and Class B shares commenced on June 1, 1998.
Class C shares were initially offered on September 1, 1998. Distribution of
Class I shares, Class R1 shares and Class R2 shares commenced on January 2,
2004. Class A shares are offered at net asset value per share plus an initial
sales charge. No sales charge applies on investments of $1 million or more (and
certain other qualified purchases) in Class A shares, but a contingent deferred
sales charge is imposed on certain redemptions of such shares within one year of
the date of purchase. Class B shares and Class C shares are offered without an
initial sales charge, although a declining contingent deferred sales charge may
be imposed on redemptions made within six years of purchase of Class B shares
and within one year of purchase of Class C shares. Class I, Class R1 and Class
R2 shares are not subject to a sales charge. The six classes of shares bear the
same voting (except for issues that relate solely to one class), dividend,
liquidation, and other rights and conditions except that Class B shares and
Class C shares are subject to higher distribution fee rates than Class A shares
and Class R2 shares under a distribution plan pursuant to Rule 12b-1 under the
1940 Act. Class I shares and Class R1 shares are not subject to a distribution
or service fee. Class R1 and Class R2 shares are authorized to pay to New York
Life Investment Management LLC, its affiliates, or third-party service
providers, as compensation for services rendered to shareholders of Class R1 or
Class R2 shares, a shareholder service fee.

The Fund's investment objective is to realize maximum long-term total return
from a combination of capital appreciation and income.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on the valuation date; such securities not
traded on the valuation date are valued at the mean of the latest quoted bid and
asked prices. Prices normally are taken from the principal market in which each
security trades. Temporary cash investments acquired over 60 days to maturity
are valued using the latest bid prices or using valuations based on a matrix
system (which considers such factors as security prices, yields, maturities, and
ratings), both as furnished by independent pricing services. Other temporary
cash investments are valued at amortized cost, which approximates market value.
Securities for which market quotations are not readily available are valued by
methods deemed in good faith by Board of Trustees to represent fair value.
Reasons for which securities may be valued in this manner include, but are not
limited to, trading for a security has been halted or suspended, a security has
been de-listed from a national exchange, or trading on a security's principal
market is temporarily closed at a time when under normal conditions it would be
open. The Fund did not hold securities at October 31, 2005, that were valued in
such manner.

(B) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (see Note 7.)

(C) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are withheld at the source.

(D) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its portfolio securities or foreign currencies. Premiums are received
and are recorded as liabilities. The liabilities are subsequently adjusted and
unrealized appreciation or depreciation is recorded to reflect the current value
of the options written. Premiums received from writing options which expire are
treated as realized gains. Premiums received from writing options which are
exercised or are cancelled in closing purchase transactions are added to the
proceeds or netted against the amount paid on the transaction to determine the
realized gain or loss. By writing a covered call option,

 18   MainStay Mid Cap Value Fund


in exchange for the premium, the Fund foregoes the opportunity for capital
appreciation above the exercise price should the market price of the underlying
security or foreign currency increase but, as long as the obligation as a writer
continues, have retained the risk of loss should the price of the underlying
security decline. By writing a covered put option, the Fund, in exchange for the
premium, accepts the risk of decline in the market value of the underlying
security or foreign currency below the exercise price. After writing a put
option, the Fund may incur a loss equal to the difference between the exercise
price of the option and the sum of the market value of the underlying security
plus the premium received from the sale of the option. A call option may be
covered by the call writer's owning the underlying security throughout the
option period. A call option may also be covered by the call writer's
maintaining liquid assets valued at greater than the exercise price of the call
written, in a segregated account with its custodian.

The Fund may purchase call and put options on its portfolio securities. The Fund
may purchase call options to protect against an increase in the price of the
security it anticipates purchasing. The Fund may purchase put options on its
securities to protect against a decline in the value of the security or to close
out covered written put positions. The Fund may also purchase options to seek to
enhance returns. Risks may arise from an imperfect correlation between the
change in market value of the securities held by the Fund and the prices of
options relating to the securities purchased or sold by the Fund and from the
possible lack of a liquid secondary market for an option. The maximum exposure
to loss for any purchased option is limited to the premium initially paid for
the option.

(E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
quarterly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

The following table discloses the current year reclassifications between net
investment loss, accumulated net realized gain on investments and additional
paid-in-capital arising from permanent differences; net assets at October 31,
2005, are not affected.

<Table>

 $1,263,215     $158,191     $(1,421,406)
 ---------------------------------------
</Table>

The reclassifications for the Fund are primarily due to the fact that net
operating losses cannot be carried forward for federal income tax purposes, real
estate investment trusts investments and foreign currency gain (loss).

(F) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on securities, other than short-term securities,
purchased for the Fund are accreted and amortized, respectively, on the constant
yield method over the life of the respective securities or, in the case of a
callable security, over the period to the first date of call. Discounts and
premiums on short-term securities are accreted and amortized, respectively, on
the straight line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(G) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(H) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at
the mean between the buying and selling rates last quoted by any major U.S. bank
at the following dates:

(i)  market value of investment securities, other assets and liabilities--at the
     valuation date.

(ii) purchases and sales of investment securities, income and expenses--at the
     date of such transactions.

The assets and liabilities are presented at the exchange rates and market values
at the close of the period. The

                                                    www.MAINSTAYfunds.com     19

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

realized and unrealized changes in net assets arising from fluctuations in
exchange rates and market prices of securities are not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains and losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments, are reflected in
unrealized foreign exchange gains or losses at year end exchange rates.

(I) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(J) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.70% on assets up to $500 million and
0.65% on assets in excess of $500 million. Effective August 1, 2005, the Manager
has entered into a written expense limitation agreement, under which the Manager
has agreed to reimburse the expenses of the Fund so that the total operating
expenses (excluding taxes, interest, litigation, extraordinary expenses, and
brokerage and other transaction expenses relating to the purchase or sale of
portfolio investments) do not exceed, on an annualized basis, 1.35% of the
average daily net assets of the Class A shares. An equivalent reimbursement, in
an equal amount of basis points, will be applied to the other share classes. The
Manager, within three years of incurring such expenses, may recoup the amount of
any management fee waiver or expense reimbursement from the Fund pursuant to
this agreement if such recoupment does not cause the Fund to exceed the expense
limitations. At October 31, 2005 the Fund had $130,177 of recoupment available.
This amount is available until October 31, 2008. This expense limitation may be
modified or terminated only with the approval of the Board of Trustees. Prior to
August 1, 2005 and after December 1, 2004, NYLIM agreed to voluntarily reimburse
the expenses of the Fund so that the total operating expenses would not exceed
on an annualized basis 1.35% of the average daily net assets of the Class A
shares, and such that there would be an equivalent reduction for the other
classes of shares. Prior to December 1, 2004, NYLIM agreed to voluntarily
reimburse the expenses of the Fund so that the total operating expenses would
not exceed on an annualized basis 1.65%, 2.40% and 2.40% of the average daily
net assets of the Class A, Class B and Class C shares, respectively, and an
equivalent amount for Class I, Class R1 and Class R2 shares. For the year ended
October 31, 2005, the Manager earned fees from the Fund in the amount of
$2,760,089, and waived its fee and/or reimbursed expenses in the amount of
$259,768.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of
0.35% of the average daily net assets of the Fund. To the extent the Manager has
agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed
to do so proportionately.

(B) DISTRIBUTION, SERVICE AND SHAREHOLDER SERVICE FEES.  The Trust, on behalf of
the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund,
with respect to Class A, Class B, Class C, and Class R2 shares, has adopted
distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1
under the 1940 Act. Pursuant to the Class A and Class R2 Plan, the Distributor
receives a monthly fee from the Fund at an annual rate of 0.25% of the average
daily net assets of the Fund's Class A and Class R2 shares, which is an expense
of the Class A and Class R2 shares of the

 20   MainStay Mid Cap Value Fund


Fund for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, the Fund pays the Distributor a
monthly fee, which is an expense of the Class B and Class C shares of the Fund,
at the annual rate of 0.75% of the average daily net assets of the Fund's Class
B and Class C shares. The Plans provide that the Class B and Class C shares of
the Fund also incur a service fee at the annual rate of 0.25% of the average
daily net asset value of the Class B or Class C shares of the Fund. Class I
shares are not subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

The Fund has adopted a shareholder services plan with respect to Class R1 and
Class R2 shares. Under the terms of this plan, Class R1 and Class R2 shares are
authorized to pay to NYLIM, its affiliates, or independent third-party
providers, as compensation for services rendered, a shareholder services fee at
the rate of 0.10% of the average daily net assets of the Fund's Class R1 and R2
shares.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $96,303 for the year ended
October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $11,626, $263,868 and $5,290, respectively, for the year ended October
31, 2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund for the year ended
October 31, 2005, amounted to $1,365,226.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus the Fund only pays a
portion of the fees identified above.

(F) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$10,396 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $66,097 for the year ended
October 31, 2005.

NOTE 4--CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, The Bank of New York acted as custodian for the Fund.

NOTE 5--FEDERAL INCOME TAX:

As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis

NOTE 10--OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those arrangements and certain other levels of trading
by fund shareholders over the period from 1999 to 2003 may have had on the
funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.9 million to nine MainStay funds. No payment was made with respect
to the MainStay Mid Cap Value Fund. NYLIM has also agreed to reimburse or pay
all expenses relating to the Board of Trustees' review of this matter and has
paid substantially all of the costs associated with the other regulatory matters
described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

 22   MainStay Mid Cap Value Fund


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders
of The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Mid Cap Value Fund ("the Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2005, and
the related statement of operations for the year then ended, and the statements
of changes in net assets and financial highlights for each of the years in the
two-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Mid Cap Value Fund of The MainStay Funds as of October 31, 2005, the
results of its operations for the year then ended, and the changes in its net
assets and financial highlights for each of the years in the two-year period
then ended, in conformity with U.S. generally accepted accounting principles.

 26   MainStay Mid Cap Value Fund


BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreement, the Board of Trustees requested and received from the
Manager and Subadvisor, and reviewed, a wide variety of information. The
Trustees also requested and received information from outside data providers and
information and analysis from a third party consultant. The Trustees considered
various industry and regulatory trends in their deliberations. In considering
approval of these Agreements, and in evaluating the fairness of the compensation
to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and Subadvisor have provided historically to the Fund, and also
generally to other series of the Trust. The Manager's services to the Trust have
included investment management services, including the selection and supervision
of portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the
day-to-day management of the portfolio, providing reports to the Manager, and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. In considering the Manager's
and Subadvisor's practices relating to best execution of portfolio trades, the
Board reviewed reports of the Fund's Brokerage Committee including with respect
to analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager, the Subadvisor and certain other service
providers, as well as the Subadvisor's attention to its compliance program. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager and Subadvisor were such that, in the context of the Board's overall
review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's underperformance relative to
certain measures over several time periods and the Subadvisor's plan designed to
improve performance, in part, through the implementation of measures intended to
reduce the volatility of the Fund's investment portfolio.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees noted the Manager's
agreement to limit the Fund's net expenses to a certain level with respect to
the Fund, with the expectation that the Manager intended, over time, to
implement measures designed to reduce the Trust's transfer agency fees. The
Trustees considered certain benefits expected for, and risks borne by, the
Manager and its affiliates, including benefits from soft dollar arrangements.
The Trustees considered the services provided to the Fund by affiliates of the
Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the
benefits to the Manager and its affiliates from those relationships. The
information provided to the Trustees indicated that the profitability to the
Manager and its affiliates arising directly from those other agreements was not
excessive. The Trustees acknowledged certain benefits to the reputation of the
Manager and its affiliates, as well to that of the Trust, from their association
with each other.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund grows, or as the Trust grows overall,
noting in particular the Manager's plans for marketing and distribut-

                                                    www.MAINSTAYfunds.com     27


ing shares of various series of the Trust. They noted the Manager's willingness
to implement contractual breakpoints, and that the contractual breakpoints in
place for the management fee were intended to provide that the Fund's
shareholders would share in benefits from economies of scale arising from the
growth of Fund assets. The Trustees acknowledged that the Fund had not yet
reached the asset level at which breakpoints would reduce the contractual
management fee to which the Fund is subject. Acknowledging the difficulty of
forecasting economies of scale, the Trustees generally expressed an intention to
monitor the Manager's profitability and consider the application of fee
breakpoints or other appropriate measures as the Board may determine from time
to time. The Trustees reviewed historical information about changes in the
Fund's expense and asset levels over time, as well as information about certain
Fund expenses that would remain fixed even as Fund assets increase and,
therefore, provide the Fund with benefits from economies of scale as the Fund
grows. The Trustees noted that, to the extent the Fund's gross expenses
currently are higher than its net expenses, economies of scale achieved through
an increase in the Fund's assets might not directly benefit the Fund through
lower net expenses. The Trustees considered various information about transfer
agency expenses, including information showing that transfer agency fees of the
Fund and a significant number of series of the Trust (although not every such
series or with respect to every share class of each series) tended to be high,
when aggregated and expressed as a percentage of the assets of certain series,
compared to the mutual fund industry average according to certain studies
reviewed by the Board and, therefore, adversely affected gross expense ratios.
The Board received information about potential effects on the Manager were it to
subsidize certain portions of the Trust's transfer agency fees. The Trustees
noted that a significant number of shareholders of the Trust's series had small
amounts invested in the series, and have considered measures intended to
increase average shareholder account size and/or otherwise reduce the Trust's
transfer agency fees and expenses, including steps that the Manager has taken to
encourage shareholders to consolidate or close small accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts, that had investment objectives similar to
that of the Fund. The Trustees took into account information provided by the
Manager or Subadvisor about the relative scope of services provided to the Fund
and to those accounts or explanations about the accounts' histories. In
considering the extent of the fees received by the Manager and Subadvisor for
providing services to the Fund, the Trustees evaluated factors such as the fees
and expenses borne by other registered funds in the market pursuing strategies
generally similar to those followed by the Fund. The Trustees considered the
Fund's historical and proposed contractual and net management fees, its
anticipated gross and net expense ratios, and various components of that expense
ratio, in comparison to other funds in comparison groupings prepared by outside
data providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.

At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/s/ CHRISTOPHER O. BLUNT


Christopher O. Blunt

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and max-imum applicable sales charges explained in this
paragraph. The graphs assume an initial investment of $10,000 and reflect the
deduction of all sales charges that would have applied for the period of
investment. Class A shares are sold with a maximum initial sales charge of 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. The fee waivers
and/or expense limitations are contractual and may be modified or terminated
only with the approval of the Board of Trustees. From inception (6/1/98) through
8/31/98, performance 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.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY GLOBAL HIGH INCOME FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balance or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

 6   MainStay Global High Income Fund


PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Gary Goodenough, Joseph Portera, and
Jeffrey H. Saxon of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests primarily in high-yield securities, including debt
securities issued by governments, and their agencies and authorities, and
corporations that are located in at least three different countries. The Fund
focuses on debt securities that generally are rated in the lower rating
categories of Moody's or S&P(1). The Fund principally invests in emerging
markets, but may also invest in established economies. In implementing this
strategy, we seek to identify investment opportunities with an approach that
includes country selection, local currency evaluation, and individual security
analysis based on such factors as financial condition and competitiveness. We
may consider a country's political stability, currency exchange rates, interest
rates, inflation, relative economic growth, and governmental policies.

During the reporting period, all of the assets and liabilities of MainStay
International Bond Fund were transferred to MainStay Global High Income Fund in
exchange for shares of MainStay Global High Income Fund.

WHAT FACTORS INFLUENCED EMERGING-MARKET DEBT DURING THE 12-MONTH REPORTING
PERIOD?

By and large, emerging-market debt performed within our expectations during the
period, buoyed by higher relative yields and continued improvement in credit
fundamentals. While credit risk remained a concern, the additional yield offered
by emerging-market securities continued to compensate buyers, and during the
12-month period ended October 31, 2005, emerging-market debt outperformed most
other fixed-income asset classes. Several other factors also influenced the
market during the reporting period. Tighter monetary policy in the U.S. caused
the yield curve to flatten, as short-term yields rose while longer-term yields
remained virtually unchanged.

WHAT ISSUES AFFECTED THE MANAGEMENT OF THE FUND DURING THE 12-MONTH REPORTING
PERIOD?

For much of the reporting period, we concentrated the portfolio on securities
with longer-term maturities and maintained a slightly longer duration than that
of the Fund's benchmark, the JPMorgan EMBI Global Diversified Index.(2) The
prices of soft and hard commodities continued to rise across the board during
the reporting period. Several events strengthened the surge in prices. Major
hurricanes in the United States disrupted refinery production and pushed oil and
gas prices higher. Even selected agreements by the Organization of the Petroleum
Exporting Countries to increase production had little if any effect on lowering
energy prices. Higher prices benefited emerging-market oil exporters such as
Mexico, Russia, and Venezuela. Precious-metals prices rose as demand from China
and India continued to expand. Higher commodity prices benefited several
investments in the Fund, including metals & mining companies Companhia
Siderurgica Nacional in Brazil and Southern Peru Copper.

HOW DID POLITICAL FACTORS AFFECT THE FUND?

In emerging markets, political risk is always an issue. During the reporting
period, there was considerable discussion about the possibility of Turkey
becoming a member of the European Union. We saw a regime change in Ecuador. In
Brazil, there was the usual "scandal sheet" of who took money and who benefited
from what. In Russia, transparency and the rule of law came into question when
President Putin used his influence to effectively renationalize parts of the oil
and natural gas industry.


Foreign securities may be subject to greater risks than U.S. investments,
including currency fluctuations, less-liquid trading markets, greater price
volatility, political and economic instability, less publicly available
information, and changes in tax or currency laws or monetary policy. These risks
are likely to be greater in emerging markets than in developed markets.
High-yield securities ("junk bonds") are generally considered speculative
because they present a greater risk of loss than higher-quality debt securities
and may be subject to greater price volatility. The Fund may invest in
derivatives, which may increase the volatility of the Fund's net asset value and
may result in a loss to the Fund. Funds that invest in bonds are subject to
credit, inflation, and interest-rate risk and can lose principal value when
interest rates rise. The Fund may experience a portfolio turnover rate of over
100% and may generate short-term capital gains which are taxable.
1. Bonds rated B by Moody's Investors Service are deemed by Moody's to generally
   lack characteristics of the desirable investment. According to Moody's,
   assurance of interest and principal payments or of maintenance of other terms
   of the contract over any long period of time may be small. Debt rated B by
   Standard & Poor's is deemed by Standard & Poor's to be more vulnerable to
   nonpayment than obligations rated BB, but it is the opinion of Standard &
   Poor's that the obligor currently has the capacity to meet its financial
   commitment on the obligation. Standard & Poor's believes that adverse
   business, financial, or economic conditions will likely impair the obligor's
   capacity or willingness to meet its financial commitment on the obligation.
   When applied to Fund holdings, ratings are based solely on the
   creditworthiness of the bonds in the portfolio and are not meant to represent
   the security or safety of the Fund.
2. See footnote on page 4 for more information on the JPMorgan EMBI Global
   Diversified Index.

                                                     www.MAINSTAYfunds.com     7


In the past, these kinds of events would have led to increased volatility. But
clearly the market has matured. Prices did drop for specific issuers, such as
those in Ecuador, but the securities quickly recovered. Over the past several
years, emerging market government and corporate issuers have strengthened their
balance sheets. With net debt reductions during the past 12 months, issuers
hoping to extend the average maturity of their external debt have taken
advantage of strong demand and historically low yields to do so. Over the years,
many issuers that lacked access to the capital markets (e.g., Mexico in 1994 and
Russia in 1998) have faced difficulties when they needed to roll over short-term
debt. With prudent debt management and rising international reserves, however,
this scenario is much less likely for most issuers.

HOW DID YOU POSITION THE FUND'S PORTFOLIO IN THIS ENVIRONMENT?

Regardless of the market environment, our philosophy is to emphasize undervalued
assets using a long-term perspective. Since emerging-market debt had already
enjoyed several years of above-average performance, we entered the reporting
period believing that volatility was likely to increase, at least over the short
term. As long as fundamentals continued to improve, however, we planned to
remain almost fully invested. As new money came into the Fund, we quickly sought
to invest it--at least until October 2005. As the U.S. Treasury sell-off gained
momentum, we became more defensive and increased the Fund's cash position.

For most of the 12 months ended October 31, 2005, we maintained our major
themes, focusing on commodity-based issuers and improving corporate credits. A
major shift for the Fund during the reporting period was our decision to add
local currency debt to the Fund's portfolio. As of October 31, 2005, local
currency emerging-market debt was approximately 3% of the Fund's net assets and
was split across the Mexican peso, the Brazilian real, the Argentine peso, the
Turkish lira, and the Colombian peso. In most cases, we have been attracted to
these currencies because of high real interest rates and strong current-account
data. Following the debt exchange in Argentina, we concluded that the local
currency offered better risk/reward characteristics than the external debt.
Since the Fund purchased the local currency debt, these bonds have contributed
positively to the Fund's overall return. The Fund's strategically overweighted
position in Russian assets also enhanced results. The yield premium investors
have demanded to own Russian debt has declined 145 basis points over the
reporting period. (A basis point is one-hundredth of a percentage point.)

The financial woes of the U.S. auto sector have received considerable publicity.
In August, we viewed this as an opportunity and elected to add a small position
in General Motors Acceptance Corp. debt to the Fund's portfolio. We felt that
under any conceivable scenario, a commitment to GMAC would be well invested. In
particular, the Fund purchased some long-term GMAC debt, and the holding has
risen since it was acquired. The increase came on news that General Motors was
looking for a strategic buyer for a majority of GMAC, a move that might help the
subsidiary regain an investment-grade rating.

As we stated earlier, we raised the Fund's cash position toward the end of the
reporting period. We also reduced the Fund's exposure to Russian debt. Given the
rally in the corporate sector, we felt that at current spread levels it would be
prudent to reduce this overweighted position. Part of the proceeds went into
cash and a portion was used to purchase Mexican dollar debt.

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 Global
High Income Fund (the "Fund").

The Fund currently offers three classes of shares. Distribution of Class A
shares and Class B shares commenced on June 1, 1998. Class C shares were
initially offered on September 1, 1998 Class A shares are offered at net asset
value per share plus an initial sales charge. No sales charge applies on
investments of $1 million or more (and certain other qualified purchases) in
Class A shares, but a contingent deferred sales charge is imposed on certain
redemptions of such shares within one year of the date of purchase. Class B
shares and Class C shares are offered without an initial sales charge, although
a declining contingent deferred sales charge may be imposed on redemptions made
within six years of purchase of Class B shares and within one year of purchase
of Class C shares. Class A shares, Class B shares and Class C shares bear the
same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights and conditions except that the Class B shares and
Class C shares are subject to higher distribution fee rates. Each class of
shares bears distribution and/or service fee payments under a distribution plan
pursuant to Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to seek to provide maximum current income by
investing primarily in high yield debt securities of non-U.S. issuers. Capital
appreciation is a secondary objective. The Fund is "non-diversified," which
means that it may invest a greater percentage of its assets than diversified
funds in a particular issuer. This may make it more susceptible than diversified
funds to risks associated with an individual issuer, and to single economic,
political or regulatory occurrences.

The Fund's principal investments include high yield securities (sometimes called
"junk bonds"), which are generally considered speculative because they present a
greater risk of loss, including default, than higher quality debt securities.
These securities pay a premium--a high interest rate or yield --because of the
increased risk of loss. These securities can also be subject to greater price
volatility.

The Fund also invests in foreign securities which carry certain risks that are
in addition to the usual risks inherent in domestic instruments. These risks
include those resulting from currency fluctuations, future adverse political and
economic developments and possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. These risks are likely to be
greater in emerging markets than in developed markets. The ability of issuers of
debt securities held by the Fund to meet their obligations may be affected by
economic and political developments in a specific country, industry or region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or brokers selected by the Fund's Manager, whose prices reflect
broker/dealer supplied valuations and electronic data processing techniques, if
such prices are deemed by the Fund's Manager to be representative of market
values, at the regular close of business of the New York Stock Exchange.
Temporary cash investments acquired over 60 days to maturity are valued using
the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments are valued at amortized cost, which approximates market value.
Foreign currency forward contracts are valued at their fair market values
determined on the basis of the mean between the last current bid and asked
prices based on dealer or exchange quotations. Securities for which market
quotations are not readily available are valued by methods deemed in good faith
by Board of Trustees to represent fair value. Reasons for which securities may
be valued in this manner include, but are not limited to, trading for a security
has been halted or suspended, a security has been de-listed from a national
exchange, or trading on a security's principal market is temporarily closed at a
time when under normal conditions it would be open. At October 31, 2005, the
Fund held securities with a value of $1,791,597 that were valued in such manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor conclude that such events may have effected the accuracy
of the last price reported on the local foreign market, the Manager or
Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of
the local price to reflect the

 20   MainStay Global High Income Fund


impact on the price of such securities as a result of such events.

(B) FOREIGN CURRENCY FORWARD CONTRACTS.  A foreign currency forward contract is
an agreement to buy or sell currencies of different countries on a specified
future date at a specified rate. During the period the forward contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking to market" such contract on a daily basis to reflect the
market value of the contract at the end of each day's trading. When the forward
contract is closed, the Fund records a realized gain or loss equal to the
difference between the proceeds from (or cost of) the closing transaction and
the Fund's basis in the contract. The Fund enters into foreign currency forward
contracts primarily to hedge its foreign currency denominated investments and
receivables and payables against adverse movements in future foreign exchange
rates or to try to enhance the Fund's returns.

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
period end to credit loss in the event of a counterparty's failure to perform
its obligations. ( See Note 6.)

(C) RESTRICTED SECURITIES.  A restricted security is a security which has been
purchased through a private offering and cannot be resold to the general public
without prior registration under the Securities Act of 1933 (the "1933 Act").
The Fund does not have the right to demand that such securities be registered.
Disposal of these securities may involve time-consuming negotiations and expense
and prompt sale at an acceptable price may be difficult. (See Note 6.)

(D) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See Note 6.)

(E) LOAN PARTICIPATIONS AND COMMITMENTS.  The Fund invests in loan
participations. Loan participations are agreements to make money available (a
"commitment") to a borrower in a specified amount, at a specified rate and
within a specified time. Such loan participations are typically senior, secured
and collateralized in nature. The Fund records an investment when the borrower
withdraws money and records interest as earned. These loans pay interest at
rates which are periodically reset by reference to a base lending rate plus a
spread. These base lending rates are generally the prime rate offered by a
designated U.S. bank or London InterBank Offered Rate (LIBOR).

The loans in which the Fund invests are generally readily marketable, but may be
subject to some restrictions on resale. The Fund may be contractually obligated
to receive approval from the agent bank and/or borrower prior to the sale of
these investments.

The Fund assumes the credit risk of the Borrower, the Selling Participant and
any other persons interpositioned between the Fund and the Borrower
("Intermediate Participants"). In the event that the Borrower, Selling
Participant or Intermediate Participants becomes insolvent or enters into
bankruptcy, the Fund may incur certain costs and delays in realizing payment, or
may suffer a loss of principal and/or interest.

Unfunded commitment represent the remaining obligation of the Fund to the
Borrower. At any point in time, up to the maturity date of the issue, the
Borrower may demand the unfunded portion. These unfunded amounts are recorded in
memorandum accounts.

(F) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are withheld at the source.

(G) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund intends to declare and pay
dividends monthly and capital gain distributions, if any, annually. Income
dividends and capital gain distributions are determined in accordance with
federal income tax regulations, which may differ from accounting principles
generally accepted in the United States of America. These "book/tax differences"
are either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their federal tax basis treatment; temporary
differences do not require reclassification.

The following table discloses the current year reclassifications between
accumulated loss, accumulated net realized gain on investments and additional
paid-in capital arising

                                                    www.MAINSTAYfunds.com     21

from permanent differences, net assets at October 31, 2005, are not affected.

</Table>

The reclassifications for the Fund are primarily due to premium amortization
adjustments, foreign currency gain (loss), and taxable over distributions of
dividends.

(H) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Interest income is
accrued as earned. Discounts and premiums on securities, other than short-term
securities, purchased for the Fund are accreted and amortized, respectively, on
the constant yield method over the life of the respective securities or, in the
case of a callable security, over the period to the first date of call.
Discounts and premiums on short-term securities are accreted and amortized,
respectively, on the straight line method. Income from payment-in-kind
securities is recorded daily based on the effective interest method of accrual.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(I) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at
the mean between the buying and selling rates last quoted by any major U.S. bank
at the following dates:

(i)  market value of investment securities, other assets and liabilities--at the
     valuation date,

(ii) purchases and sales of investment securities, income and expenses--at the
     date of such transactions.

The assets and liabilities are presented at the exchange rates and market values
at the close of the period. The realized and unrealized changes in net assets
arising from fluctuations in exchange rates and market prices of securities are
not separately presented. The unrealized changes in net assets arising from
fluctuations in exchange rates and market prices of securities are not
separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments, are reflected in
unrealized foreign exchange gains or losses at period end exchange rates.

(J) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(K) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

Certain amounts have been reclassified to conform to current year presentation.
Such reclassifications had no effect on the Fund's net income or capital.

(L) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

 22   MainStay Global High Income Fund


The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.70% on assets up to $500 million and
0.65% on assets over $500 million. Effective August 1, 2005, the Manager has
entered into a written expense limitation agreement, under which the Manager has
agreed to reimburse the expenses of the Fund so that the total operating
expenses (excluding taxes, interest, litigation, extraordinary expenses, and
brokerage and other transaction expenses relating to the purchase or sale of
portfolio investments) do not exceed, on an annualized basis, 1.40% of the
average daily net assets of the Class A shares. An equivalent reimbursement, in
an equal amount of basis points, will be applied to the other share classes. The
Manager, within three years of incurring such expenses, may recoup the amount of
any management fee waiver or expense reimbursement from the Fund pursuant to
this agreement if such recoupment does not cause the Fund to exceed the expense
limitations. At October 31, 2005, the Fund had $38,120 of recoupment available.
This amount is available until October 31, 2008. This expense limitation may be
modified or terminated only with the approval of the Board of Trustees. Prior to
August 1, 2005, (and after December 1, 2004), NYLIM voluntarily agreed to
reimburse the expenses of the Fund so that total annual fund operating expenses
would not exceed on an annualized basis 1.51% of the average daily net assets of
the Class A shares, and such that there would be an equivalent reduction for the
other classes of shares. Prior to December 1, 2004, the manager voluntarily
agreed to reimburse the expenses of the Fund so that total annual fund operating
expenses would not exceed on an annualized basis 1.70%, 2.45% and 2.45% of the
average daily net assets of the Class A, Class B, and Class C shares,
respectively. For the year ended October 31, 2005, the Manager earned fees from
the Fund in the amount of $955,904, and reimbursed expenses in the amount of
$38,120.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of
0.35% of the average daily net assets of the Fund. To the extent the Manager has
agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed
to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, has adopted distribution plans (the "Plans") in accordance
with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A
Plan, the Distributor receives a monthly fee from the Fund at an annual rate of
0.25% of the average daily net assets of the Fund's Class A shares, which is an
expense of the Class A shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly fee, which is an expense of the Class B and
Class C shares of the Fund, at the annual rate of 0.75% of the average daily net
assets of the Fund's Class B and Class C shares. The Plans provide that the
Class B and Class C shares of the Fund also incur a service fee at the annual
rate of 0.25% of the average daily net asset value of the Class B or Class C
shares of the Fund. The Plans provide that the distribution and service fees are
payable to the Distributor regardless of the amounts actually expended by the
Distributor for distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $54,775 for the year ended
October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $1,239, $59,632 and $15,023, respectively, for the year ended October
31, 2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund for the year ended
October 31, 2005, amounted to $408,624.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus the Fund only pays a
portion of the fees identified above.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(F) CAPITAL.  At October 31, 2005, New York Life held shares of Class A with a
net asset values of $17,623,861. This represents 20.4% of the Class A net assets
and 10.2% of the Fund's total net assets at period end.

(G) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$3,787 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $40,322 for the year ended
October 31, 2005.

NOTE 4--CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, The Bank of New York acted as custodian for the Fund.
NOTE 5--FEDERAL INCOME TAX:

As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis
were as follows:

<Table>

              ACCUMULATED         OTHER                        TOTAL

 -------------------------------------------------------------------
 -------------------------------------------------------------------
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals,
and mark-to-market of unrealized foreign currency forward contract gain (loss).

At October 31, 2005, for federal income tax purposes, capital loss carryforwards
of $1,260,445 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.

NOTE 11--OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completely responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those agreements and certain other levels of trading by
fund shareholders over the period from 1999 to 2003 may have had on the Funds.
As a result of this review, in December 2005, NYLIM made payments totaling $5.9
million to nine MainStay funds. The amount paid to the MainStay Global High
Income Fund was $11,000. NYLIM has also agreed to reimburse or pay all expenses
relating to the Board of Trustees' review of this matter, and has paid
substantially all of the costs associated with the other regulatory matters
described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Global High Income Fund ("the
Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2005, and the related statement of operations for the year then ended, and the
statements of changes in net assets and financial highlights for each of the
years in the two-year period then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The financial highlights for the
periods presented through October 31, 2003, were audited by other auditors,
whose report dated December 18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Global High Income Fund of The MainStay Funds as of October 31, 2005,
the results of its operations for the year then ended, and the changes in its
net assets and financial highlights for each of the years in the two-year period
then ended, in conformity with U.S. generally accepted accounting principles.

 30   MainStay Global High Income Fund


BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreement, the Board of Trustees requested and received from the
Manager and Subadvisor, and reviewed, a wide variety of information. The
Trustees also requested and received information from outside data providers and
information and analysis from a third party consultant. The Trustees considered
various industry and regulatory trends in their deliberations. In considering
approval of these Agreements, and in evaluating the fairness of the compensation
to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and Subadvisor have provided historically to the Fund, and also
generally to other series of the Trust. The Manager's services to the Trust have
included investment management services, including the selection and supervision
of portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the
day-to-day management of the portfolio, providing reports to the Manager, and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. In considering the Manager's
and Subadvisor's practices relating to best execution of portfolio trades, the
Board reviewed reports of the Fund's Brokerage Committee including with respect
to analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager, the Subadvisor and certain other service
providers, as well as the Subadvisor's attention to its compliance program. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager and Subadvisor were such that, in the context of the Board's overall
review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's better-than-average performance
when compared over several time periods with funds concluded by Trustees to be
peers of the Fund.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees noted the Manager's
agreement to limit the Fund's net expenses to a certain level with respect to
the Fund, with the expectation that the Manager intended, over time, to
implement measures designed to reduce the Trust's transfer agency fees. The
Trustees considered certain benefits expected for, and risks borne by, the
Manager and its affiliates, including benefits from soft dollar arrangements.
The Trustees considered the services provided to the Fund by affiliates of the
Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the
benefits to the Manager and its affiliates from those relationships. The
information provided to the Trustees indicated that the profitability to the
Manager and its affiliates arising directly from those other agreements was not
excessive. The Trustees acknowledged certain benefits to the reputation of the
Manager and its affiliates, as well to that of the Trust, from their association
with each other.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund grows, or as the Trust grows overall,
noting in particular the Manager's plans for marketing and distributing shares
of various series of the Trust. They noted the Manager's willingness to
implement contractual

                                                    www.MAINSTAYfunds.com     31


breakpoints, and that the contractual breakpoints in place for the management
fee were intended to provide that the Fund's shareholders would share in
benefits from economies of scale arising from the growth of Fund assets. The
Trustees acknowledged that the Fund had not yet reached the asset level at which
breakpoints would reduce the contractual management fee to which the Fund is
subject. Acknowledging the difficulty of forecasting economies of scale, the
Trustees generally expressed an intention to monitor the Manager's profitability
and consider the application of fee breakpoints or other appropriate measures as
the Board may determine from time to time. The Trustees reviewed historical
information about changes in the Fund's expense and asset levels over time, as
well as information about certain Fund expenses that would remain fixed even as
Fund assets increase and, therefore, provide the Fund with benefits from
economies of scale as the Fund grows. The Trustees noted that, to the extent the
Fund's gross expenses currently are higher than its net expenses, economies of
scale achieved through an increase in the Fund's assets might not directly
benefit the Fund through lower net expenses. The Trustees considered various
information about transfer agency expenses, including information showing that
transfer agency fees of the Fund and a significant number of series of the Trust
(although not every such series or with respect to every share class of each
series) tended to be high, when aggregated and expressed as a percentage of the
assets of certain series, compared to the mutual fund industry average according
to certain studies reviewed by the Board and, therefore, adversely affected
gross expense ratios. The Board received information about potential effects on
the Manager were it to subsidize certain portions of the Trust's transfer agency
fees. The Trustees noted that a significant number of shareholders of the
Trust's series had small amounts invested in the series, and have considered
measures intended to increase average shareholder account size and/or otherwise
reduce the Trust's transfer agency fees and expenses, including steps that the
Manager has taken to encourage shareholders to consolidate or close small
accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts, that had investment objectives similar to
that of the Fund. The Trustees took into account information provided by the
Manager or Subadvisor about the relative scope of services provided to the Fund
and to those accounts or explanations about the accounts' histories. In
considering the extent of the fees received by the Manager and Subadvisor for
providing services to the Fund, the Trustees evaluated factors such as the fees
and expenses borne by other registered funds in the market pursuing strategies
generally similar to those followed by the Fund. The Trustees considered the
Fund's historical and proposed contractual and net management fees, its
anticipated gross and net expense ratios, and various components of that expense
ratio, in comparison to other funds in comparison groupings prepared by outside
data providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

                    Annual Report
                    October 31, 2005


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.
At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/S/ CHRISTOPHER O. BLUNT


Christopher O. Blunt
President

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

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY CONVERTIBLE FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Edward Silverstein, CFA, and Edmund C.
Spellman of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in convertible securities
such as bonds, debentures, corporate notes, and preferred stocks or other
securities that are convertible into common stock or the cash value of a stock
or a basket or index of equity securities. The Fund takes a flexible approach by
investing in a broad range of securities of a variety of companies and
industries. The Fund invests in high-yield debt securities and may invest
without restriction in securities rated BB or B by S&P or Ba or B by Moody's.(1)
The balance of the Fund may be invested or held in nonconvertible debt, equity
securities that do not pay regular dividends, U.S. government securities, and
cash or cash equivalents. In selecting convertible securities for purchase or
sale, we take into account a variety of investment considerations, including the
potential return of the common stock, credit risk, projected interest return,
and the premium for the convertible security relative to the underlying common
stock. We may sell a security if we no longer believe it will contribute to
meeting the investment objective of the Fund.

WHAT FACTORS INFLUENCED THE CONVERTIBLE BOND MARKET DURING THE 12 MONTHS ENDED
OCTOBER 31, 2005?

Convertible bonds are hybrid instruments whose results depend on the performance
of related equity and fixed-income markets. Although the stock market was
volatile during the reporting period, the S&P 500(R) Index advanced 8.72% during
the 12 months ended October 31, 2005. During the same period, the Federal Open
Market Committee raised the federal funds target rate eight times, with a
25-basis-point increase on each occasion. (A basis point is one-hundredth of a
percentage point.) Rising interest rates and widening credit spreads depressed
the value of straight corporate debt and convertible bonds. For the 12-month
period, energy equipment & services convertibles were strong, while airline and
automotive convertibles were weak.

HOW DID THE FUND PERFORM RELATIVE TO THE CONVERTIBLE MARKET AS A WHOLE?

Excluding all sales charges, all of the Fund's share classes outperformed the
Merrill Lynch All Convertible Securities Index,(2) the Fund's primary benchmark,
during the 12 months ended October 31, 2005. The Fund's outperformance resulted
largely from security and sector selection. Continuing a theme from last year,
the Fund remained heavily overweighted in the energy equipment & services
industry, with large positions in the convertible bonds of Halliburton,
Schlumberger, and Pride International, all of which contributed positively to
the Fund's performance. Specific investments in other sectors also outperformed
the Fund's primary benchmark. Automotive and airlines issues tended to
underperform, so our decision to underweight the Fund in these areas helped
relative performance.

WHICH OF THE FUND'S SECURITIES WERE STRONG PERFORMERS DURING THE REPORTING
PERIOD?

The best performer for the Fund in terms of absolute dollar gain was Whole Foods
Markets, followed by


High-yield securities ("junk bonds") are generally considered speculative
because they present a greater risk of loss than higher-quality debt securities
and may be subject to greater price volatility. Issuers of convertible
securities may not be as financially strong as those issuing securities with
higher credit ratings and may be more vulnerable to changes in the economy. If
an issuer stops making interest payments, principal payments, or both on its
convertible securities, these securities may become worthless and the Fund could
lose its entire investment in them.

1. Debt rated BB by Standard & Poor's is deemed by Standard & Poor's to be less
   vulnerable to nonpayment than other speculative issues. In the opinion of
   Standard & Poor's, however, debt rated BB faces major ongoing uncertainties
   or exposure to adverse business, financial, or economic conditions which
   could lead to the obligor's inadequate capacity to meet its financial
   commitment on the obligation. Debt rated B by Standard & Poor's is deemed by
   Standard & Poor's to be more vulnerable to nonpayment than obligations rated
   BB, but it is the opinion of Standard & Poor's that the obligor currently has
   the capacity to meet its financial commitment on the obligation. Standard &
   Poor's believes that adverse business, financial, or economic conditions will
   likely impair the obligor's capacity or willingness to meet its financial
   commitment on the obligation. Bonds rated Ba by Moody's Investors Service are
   judged by Moody's to have speculative elements, and Moody's believes that the
   future of the bonds cannot be considered well- assured. Moody's believes that
   often, the protection of interest and principal payments on such bonds may be
   very moderate and thereby not well safeguarded during both good and bad times
   in the future. According to Moody's, uncertainty of position characterizes
   bonds in this class. Bonds rated B by Moody's Investors Service are deemed by
   Moody's to generally lack characteristics of the desirable investment.
   According to Moody's, assurance of interest and principal payments or of
   maintenance of other terms of the contract over any long period of time may
   be small. When applied to Fund holdings, ratings are based solely on the
   creditworthiness of the bonds in the portfolio and are not meant to represent
   the security or safety of the Fund.

Halliburton, Pride International, and Teva Pharmaceutical Industries.

Whole Foods Markets benefited from same-store sales and earnings that remained
well above analysts' expectations. We have confidence in the company's excellent
management, fundamental business, pristine balance sheet, and excess cash flow.
High energy prices and increased exploration and production activity benefited
energy equipment & services companies Halliburton, Pride International, and
Schlumberger. The share prices and convertible bonds of these companies rose
sharply during the reporting period. Convertible bonds of Teva Pharmaceutical
Industries advanced on positive developments in the generic drug market. The
company obtained the right to distribute generic Allegra for allergies and
generic Effexor for depression. A court decision granted Teva Pharmaceutical
Industries the right to be the exclusive generic seller of Pravachol, a drug
developed by Bristol-Meyers Squibb.

Other strong performers included Sirius Satellite Radio, Amerada Hess, and
Chesapeake Energy. Sirius Satellite Radio convertibles advanced on faster-than-
expected subscriptions. In January 2006, radio personality Howard Stern will
begin airing on Sirius, which provides a variety of commercial-free music and
talk offerings. Amerada Hess and Chesapeake Energy, two oil & gas exploration &
production companies, benefited from high oil and natural gas prices. Since U.S.
refining capacity has not increased in decades and demand for gasoline and
heating oil has remained high, refining operations at Amerada Hess enjoyed
strong margins.

WHICH SECURITIES DETRACTED FROM THE FUND'S PERFORMANCE?

In terms of dollars lost, the Fund's worst-performing position was a convertible
bond of biotechnology company Elan Capital. Other detractors included securities
of Lucent Technologies, Ford Motor, International Paper, and Flextronics
International.

Elan Capital's common stock tumbled in February 2005 when a recently introduced
multiple sclerosis therapy, Tysabri, was pulled from the market. The Fund held
convertible bonds and convertible preferred shares of Lucent Technologies, which
declined when the company's profitability failed to meet investor expectations.
Although the Fund was underweighted in the automobile industry, a Ford Motor
convertible preferred suffered when the company faced poor vehicle sales, weak
resale values, and retiree and health care costs that were above
the industry's averages.

International Paper's convertible bonds remained weak while the market continued
to wait for the paper & forest products industry to feel the combined effects of
global economic growth and high commodity prices. We recently sold some of our
other forest products holdings, such as Bowater and Smurfit Stone Container, but
the Fund continues to hold International Paper. Flextronics International
provides contract manufacturing services for electronics products. The company's
stock and convertible bonds declined sharply in October 2005 after the company
reported disappointing sales and earnings. We continue to hold the company's
convertible bonds because we believe the securities have limited downside risk.

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE FUND'S FISCAL YEAR?

We added to the Fund's convertible bond position in Hilton Hotels on strong
lodging-industry fundamentals. Hilton derives a high percentage of its revenues
from New York and Hawaii, which are strong mar-
kets, and the company is generating large amounts of free cash flow because
nearly all of the revenue from increased room rates falls to the bottom line.

We purchased Diamond Offshore Drilling convertible bonds to replace the Fund's
holdings in BJ Services, which were called by the issuer. Diamond Offshore,
which owns drilling rigs and leases them to exploration & production companies,
has benefited from new leases, higher day rates, and the ongoing search for
additional energy reserves.

Amgen is a leading biotechnology company, perhaps best known for products that
help oncology and dialysis patients boost red-blood-cell production. The
company's promising pipeline of colon cancer, osteoporosis, and arthritis
offerings is expected to help Amgen's share price rise, and we purchased the
company's convertible bonds to participate in the upside potential. The bonds
have an attractive put feature that significantly reduces downside risk without
limiting upside potential.

The Fund added to its position in Amerada Hess convertible preferred shares to
take advantage of several potential catalysts that may increase the price of the
securities. The company's hedging strategies and its plans to return operations
to Libya may help the company's long-term outlook.

We purchased Amazon.com convertible bonds for the Fund because they offer high
current yield, limited downside risk, and maturity in less than four years.
Although we are not bullish on the stock, the bonds are not particularly
sensitive to Amazon.com's common stock performance. We believe that with

 8   MainStay Convertible Fund


Amazon.com's excellent balance sheet, the bonds will be easily paid off when
they mature.

WERE THERE ANY SIGNIFICANT SALES DURING THE REPORTING PERIOD?

We sold the Fund's Burlington Northern Santa Fe convertible bonds because we
believed that the share price fully reflected the positive outlook for the
company's rail transportation business. We eliminated the Fund's position in
Goodyear Tire & Rubber convertible bonds when we felt that the shares were fully
valued. Full valuation also accounted for our sales of the Fund's convertible
preferred shares of Northrop Grumman. When Symantec announced its intent to
acquire software company Veritas Software, we sold the Fund's position in
Symantec convertible bonds. In our opinion, the acquisition signaled that
Symantec's core business, security software, was slowing. We sold the Fund's
convertible preferred shares of Fannie Mae after a substantial decline in the
company's common share price. Although the Fund's defensive position was not
hurt as much as the common stock, we saw limited upside potential in the
preferred.

HOW DID THE FUND'S WEIGHTINGS CHANGE DURING THE REPORTING PERIOD?

With the sale of Navistar and Cummins, which we believe had little remaining
upside potential, the Fund's weighting in industrial/cyclicals declined during
the reporting period. Sales of forest products holdings largely accounted for a
drop in our allocation to the materials sector. The Fund's weighting in energy
declined slightly from the beginning of the reporting period to the end of
October. In July, the Fund's aggregate energy holdings approached a level that
we felt was too high for a diversified Fund.

The Fund's allocation to financials increased during the reporting period. The
Fund purchased significant positions in convertible bonds of US Bancorp and
Sallie Mae that offered substantial upside participation in the respective
companies' common stock with virtually no downside participation or
interest-rate risk. The Fund more than doubled its telecommunication services
allocation from the beginning of the period to the end. We increased the Fund's
Verizon convertible-bond holdings and initiated a position in NII Holdings,
which provides mobile communications services in Latin America.

HOW DID THE FUND'S WEIGHTINGS COMPARE WITH THOSE OF THE MERRILL LYNCH ALL
CONVERTIBLE SECURITIES INDEX?

As of October 31, 2005, the Fund was significantly overweighted in energy
relative to the Merrill Lynch All Convertible Securities Index. On the same
date, the Fund was substantially underweighted in technology, because we felt
that most technology companies were selling at fairly high valuations given
their cyclical nature and less-than-stellar fundamentals. The Fund was
overweighted in consumer staples, primarily because of our large position in
Whole Foods Markets. Other sectors did not deviate materially from the Index. In
health care, industrials, and materials, the Fund's weightings were slightly
lower than those of the Fund's benchmark. In telecommunications, financials, and
utilities, the Fund's weightings were slightly higher than those of the Merrill
Lynch All Convertible Securities Index.

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
Convertible Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares. Class A shares, whose
distribution commenced on January 3, 1995, are offered at net asset value per
share plus an initial sales charge. No sales charge applies on investments of $1
million or more (and certain other qualified purchases) in Class A shares, but a
contingent deferred sales charge is imposed on certain redemptions of such
shares within one year of the date of purchase. Class B shares and Class C
shares are offered without an initial sales charge, although a declining
contingent deferred sales charge may be imposed on redemptions made within six
years of purchase of Class B shares and within one year of purchase of Class C
shares. Distribution of Class B shares and Class C shares commenced on May 1,
1986 and September 1, 1998, respectively. Class A shares, Class B shares and
Class C shares bear the same voting (except for issues that relate solely to one
class), dividend, liquidation and other rights and conditions except that the
Class B shares and Class C shares are subject to higher distribution fee rates.
Each class of shares bears distribution and/or service fee payments under a
distribution plan pursuant to Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to seek capital appreciation together with
current income.

The Fund invests in high yield securities (sometimes called "junk bonds"), which
are generally considered speculative because they present a greater risk of
loss, including default, than higher quality debt securities. These securities
pay a premium -- a high interest rate or yield -- because of the increased risk
of loss. These securities can also be subject to greater price volatility.

The Fund also invests in foreign securities which carry certain risks that are
in addition to the usual risks inherent in domestic instruments. These risks
include those resulting from currency fluctuations, future adverse political and
economic developments and possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. These risks are likely to be
greater in emerging markets than in developed markets. The ability of issuers of
debt securities held by the Fund to meet their obligations may be affected by
economic and political developments in a specific country, industry or region.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or brokers selected by the Fund's Manager, whose prices reflect
broker/dealer supplied valuations and electronic data processing techniques, if
such prices are deemed by the Fund's Manager to be representative of market
values, at the regular close of business of the New York Stock Exchange. Equity
securities are valued at the latest quoted sales prices as of the close of
trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the
valuation date; such securities not traded on the valuation date are valued at
the mean of the latest quoted bid and asked prices. Prices normally are taken
from the principal market in which each security trades. Options contracts are
valued at the last posted settlement price on the market where such options are
principally traded. Temporary cash investments acquired over 60 days to maturity
are valued using the latest bid prices or using valuations based on a matrix
system (which considers such factors as security prices, yields, maturities, and
ratings), both as furnished by independent pricing services. Other temporary
cash investments are valued at amortized cost, which approximates market value.
Securities for which market quotations are not readily available are valued by
methods deemed in good faith by Board of Trustees to represent fair value.
Reasons for which securities may be valued in this manner include, but are not
limited to, trading for a security has been halted or suspended, a security has
been de-listed from a national exchange, or trading on a security's principal
market is temporarily closed at a time when under normal conditions it would be
open. At October 31, 2005, the Fund held securities with a value of $1,457 that
were valued in such manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor conclude that such events may have effected the accuracy
of the last price reported on the local foreign market, the Manager or
Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of
the local price to reflect the impact on the price of such securities as a
result of such events.

 20   MainStay Convertible Fund


(B) FOREIGN CURRENCY FORWARD CONTRACTS.  A foreign currency forward contract is
an agreement to buy or sell currencies of different countries on a specified
future date at a specified rate. During the period the forward contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking to market" such contract on a daily basis to reflect the
market value of the contract at the end of each day's trading. When the forward
contract is closed, the Fund records a realized gain or loss equal to the
difference between the proceeds from (or cost of) the closing transaction and
the Fund's basis in the contract. The Fund enters into foreign currency forward
contracts primarily to hedge its foreign currency denominated investments and
receivables and payables against adverse movements in future foreign exchange
rates or to try to enhance the Fund's returns.

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
period end to credit loss in the event of a counterparty's failure to perform
its obligations.

(C) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its portfolio securities or foreign currencies. Premiums are received
and are recorded as liabilities. The liabilities are subsequently adjusted and
unrealized appreciation or depreciation is recorded to reflect the current value
of the options written. Premiums received from writing options which expire are
treated as realized gains. Premiums received from writing options which are
exercised or are cancelled in closing purchase transactions are added to the
proceeds or netted against the amount paid on the transaction to determine the
realized gain or loss. By writing a covered call option, in exchange for the
premium, the Fund foregoes the opportunity for capital appreciation above the
exercise price should the market price of the underlying security or foreign
currency increase but, as long as the obligation as a writer continues, have
retained the risk of loss should the price of the underlying security decline.
By writing a covered put option, the Fund, in exchange for the premium, accepts
the risk of decline in the market value of the underlying security or foreign
currency below the exercise price. After writing a put option, the Fund may
incur a loss equal to the difference between the exercise price of the option
and the sum of the market value of the underlying security plus the premium
received from the sale of the option. A call option may be covered by the call
writer's owning the underlying security throughout the option period. A call
option may also be covered by the call writer's maintaining liquid assets valued
at greater than the exercise price of the call written, in a segregated account
with its custodian.

The Fund may purchase call and put options on its portfolio securities. The Fund
may purchase call options to protect against an increase in the price of the
security it anticipates purchasing. The Fund may purchase put options on its
securities to protect against a decline in the value of the security or to close
out covered written put positions. The Fund may also purchase options to seek to
enhance returns. Risks may arise from an imperfect correlation between the
change in market value of the securities held by the Fund and the prices of
options relating to the securities purchased or sold by the Fund and from the
possible lack of a liquid secondary market for an option. The maximum exposure
to loss for any purchased option is limited to the premium initially paid for
the option.

(D) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See Note 7.)

(E) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are withheld at the source.

(F) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
quarterly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

(G) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on securities, other than short-term securities,
purchased for the Fund are accreted and amortized, respectively, on the constant
yield method over the life of the respective securities or, in the case of a
callable security, over the period to the first date of call. Discounts and
premiums on short-term securities are accreted and amortized, respectively, on
the straight line method. Income from payment-in-kind securities is recorded
daily based on the effective interest method of accrual.

The investment income and realized and unrealized gains and losses on
investments of the Fund are allocated to separate classes of shares based upon
their relative net assets on the date the income is earned or realized and
unrealized gains and losses are incurred.

(H) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at
the mean between the buying and selling rates last quoted by any major U.S. bank
at the following dates:

(i)  market value of investment securities, other assets and liabilities -- at
     the valuation date,

(ii) purchases and sales of investment securities, income and expenses -- at the
     date of such transactions.

The assets and liabilities are presented at the exchange rates and market values
at the close of the period. The realized and unrealized changes in net assets
arising from fluctuations in exchange rates and market prices of securities are
not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments, are reflected in
unrealized foreign exchange gains or losses at period end exchange rates.

(I) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(J) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(K) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.72% on assets up to $500 million, 0.67%
on assets from $500 million to $1 billion and 0.62% on assets in excess of $1
billion. NYLIM has voluntarily agreed to waive its management fee by 0.05% to
0.67% on assets up to $500 million, 0.62% on assets from $500 million to $1
billion and 0.57% on assets in excess of $1 billion. Effective August 1, 2005,
the Manager has entered into a written expense limitation agreement, under which
the Manager has agreed to reimburse the expenses of the Fund so that the total

 22   MainStay Convertible Fund


operating expenses (excluding taxes, interest, litigation, extraordinary
expenses, and brokerage and other transaction expenses relating to the purchase
or sale of portfolio investments) do not exceed, on an annualized basis, 1.20%
of the average daily net assets of the Class A shares. An equivalent
reimbursement, in an equal amount of basis points, will be applied to the other
share classes. The Manager, within three years of incurring such expenses, may
recoup the amount of any management fee waiver or expense reimbursement from the
Fund pursuant to this agreement if such recoupment does not cause the Fund to
exceed the expense limitations. At October 31, 2005, the Fund had $213,955 of
recoupment available. This amount is available until October 31, 2008. This
expense limitation may be modified or terminated only with the approval of the
Board of Trustees. Prior to August 1, 2005 and after December 1, 2004, NYLIM had
agreed to voluntarily reimburse the expenses of the Fund so that total annual
fund operating expenses would not exceed on an annualized basis 1.20% of the
average daily net assets of the Class A shares, and such that there would be an
equivalent reduction for the other classes of shares. For the year ended October
31, 2005, the Manager earned fees from the Fund in the amount of $3,836,288, and
waived its fees and/or reimbursed expenses in the amount of $935,148.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager paid the Subadvisor a monthly fee of 0.36% of the Fund's
average daily net assets on assets up to $500 million, 0.335% on assets from
$500 million to $1 billion and 0.31% on assets in excess of $1 billion. To the
extent the Manager has agreed to reimburse expenses of the Fund, the Subadvisor
has voluntarily agreed to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, has adopted distribution plans (the "Plans") in accordance
with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A
Plan, the Distributor receives a monthly fee from the Fund at an annual rate of
0.25% of the average daily net assets of the Fund's Class A shares, which is an
expense of the Class A shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly fee, which is an expense of the Class B and
Class C shares of the Fund, at the annual rate of 0.75% of the average daily net
assets of the Fund's Class B and Class C shares. The Plans provide that the
Class B and Class C shares of the Fund also incur a service fee at the annual
rate of 0.25% of the average daily net asset value of the Class B or Class C
shares of the Fund. The Plans provide that the distribution and service fees are
payable to the Distributor regardless of the amounts actually expended by the
Distributor for distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $47,455 for the year ended
October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $2,503, $259,488 and $3,639, respectively, for the year ended October
31, 2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund for the year ended
October 31, 2005, amounted to $1,654,776.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus the Fund only pays a
portion of the fees identified above.

(F) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$13,858 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services

                                                    www.MAINSTAYfunds.com     23

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

provided to the Fund by the Manager amounted to $80,193 for the year ended
October 31, 2005.

NOTE 4 -- CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, State Street Bank and Trust Company acted as custodian for
the Fund.

NOTE 5 -- FEDERAL INCOME TAX:

As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis
were as follows:

<Table>
<Caption>
    UNDISTRIBUTED   ACCUMULATED                      TOTAL
      ORDINARY      CAPITAL AND     UNREALIZED    ACCUMULATED

      $406,763      $(46,602,275)  $20,794,514    $(25,400,998)
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals.

At October 31, 2005, for federal income tax purposes, capital loss carryforwards
of $46,602,275 were available as shown in the table below, to the extent
provided by the regulations to offset future realized gains of the Fund through
the years indicated. To the extent that these loss carryforwards are used to
offset future capital gains, it is probable that the capital gains so offset
will not be distributed to shareholders.

NOTE 6 -- PURCHASES AND SALES OF SECURITIES (IN 000'S):

During the year ended October 31, 2005, purchases and sales of securities, other
than short-term securities, were $479,140 and $556,619, respectively.

NOTE 7 -- PORTFOLIO SECURITIES LOANED:

As of October 31, 2005, the Fund had securities on loan with an aggregate market

at amortized cost.

NOTE 8 -- LINE OF CREDIT:

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

NOTE 10 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those arrangements and certain other levels of trading
by fund shareholders over the period from 1999 to 2003 may have had on the
funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.9 million to nine MainStay funds. No payment was made with respect
to the MainStay Convertible Fund. NYLIM has also agreed to reimburse or pay all
expenses relating to the Board of Trustees' review of this matter and has paid
substantially all of the costs associated with the other regulatory matters
described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Convertible Fund ("the Fund"), one
of the funds constituting The MainStay Funds, as of October 31, 2005, and the
related statement of operations for the year then ended, and the statements of
changes in net assets and financial highlights for each of the years in the
two-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Convertible Fund of The MainStay Funds as of October 31, 2005, the
results of its operations for the year then ended, and the changes in its net
assets and financial highlights for each of the years in the two-year period
then ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreement, the Board of Trustees requested and received from the
Manager and Subadvisor, and reviewed, a wide variety of information. The
Trustees also requested and received information from outside data providers and
information and analysis from a third party consultant. The Trustees considered
various industry and regulatory trends in their deliberations. In considering
approval of these Agreements, and in evaluating the fairness of the compensation
to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and Subadvisor have provided historically to the Fund, and also
generally to other series of the Trust. The Manager's services to the Trust have
included investment management services, including the selection and supervision
of portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the
day-to-day management of the portfolio, providing reports to the Manager, and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. In considering the Manager's
and Subadvisor's practices relating to best execution of portfolio trades, the
Board reviewed reports of the Fund's Brokerage Committee including with respect
to analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager, the Subadvisor and certain other service
providers, as well as the Subadvisor's attention to its compliance program. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager and Subadvisor were such that, in the context of the Board's overall
review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's underperformance over certain
recent periods, a short-term period of significant underperformance in 2003 that
has adversely affected the Fund's relative performance over various time
periods, recent change of personnel on the portfolio management team serving the
Fund, and recent improvements in the Fund's performance resulting in the Fund's
having improved comparative performance against a group of Funds concluded by
the Trustees to be peers of the Fund.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees noted the Manager's
agreement to limit the Fund's net expenses to a certain level with respect to
the Fund, with the expectation that the Manager intended, over time, to
implement measures designed to reduce the Trust's transfer agency fees. The
Trustees considered certain benefits expected for, and risks borne by, the
Manager and its affiliates, including benefits from soft dollar arrangements.
The Trustees considered the services provided to the Fund by affiliates of the
Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the
benefits to the Manager and its affiliates from those relationships. The
information provided to the Trustees indicated that the profitability to the
Manager and its affiliates arising directly from those other agreements was not
excessive. The Trustees acknowledged certain benefits to the reputation of the
Manager and its affiliates, as well to that of the Trust, from their association
with each other.

 30   MainStay Convertible Fund


The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund grows, or as the Trust grows overall,
noting in particular the Manager's plans for marketing and distributing shares
of various series of the Trust. They noted the Manager's willingness to
implement contractual breakpoints, and that the contractual breakpoints in place
for the management fee were intended to provide that the Fund's shareholders
would share in benefits from economies of scale arising from the growth of Fund
assets. The Trustees noted that the Fund's contractual management fee had been
reduced in accordance with the terms of the breakpoint schedule applicable to
the Fund. Acknowledging the difficulty of forecasting economies of scale, the
Trustees generally expressed an intention to monitor the Manager's profitability
and consider the application of fee breakpoints or other appropriate measures as
the Board may determine from time to time. The Trustees reviewed historical
information about changes in the Fund's expense and asset levels over time, as
well as information about certain Fund expenses that would remain fixed even as
Fund assets increase and, therefore, provide the Fund with benefits from
economies of scale as the Fund grows. The Trustees noted that, to the extent the
Fund's gross expenses currently are higher than its net expenses, economies of
scale achieved through an increase in the Fund's assets might not directly
benefit the Fund through lower net expenses. The Trustees considered various
information about transfer agency expenses, including information showing that
transfer agency fees of the Fund and a significant number of series of the Trust
(although not every such series or with respect to every share class of each
series) tended to be high, when aggregated and expressed as a percentage of the
assets of certain series, compared to the mutual fund industry average according
to certain studies reviewed by the Board and, therefore, adversely affected
gross expense ratios. The Board received information about potential effects on
the Manager were it to subsidize certain portions of the Trust's transfer agency
fees. The Trustees noted that a significant number of shareholders of the
Trust's series had small amounts invested in the series, and have considered
measures intended to increase average shareholder account size and/or otherwise
reduce the Trust's transfer agency fees and expenses, including steps that the
Manager has taken to encourage shareholders to consolidate or close small
accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts, that had investment objectives similar to
that of the Fund. The Trustees took into account information provided by the
Manager or Subadvisor about the relative scope of services provided to the Fund
and to those accounts or explanations about the accounts' histories. In
considering the extent of the fees received by the Manager and Subadvisor for
providing services to the Fund, the Trustees evaluated factors such as the fees
and expenses borne by other registered funds in the market pursuing strategies
generally similar to those followed by the Fund. The Trustees considered the
Fund's historical and proposed contractual and net management fees, its
anticipated gross and net expense ratios, and various components of that expense
ratio, in comparison to other funds in comparison groupings prepared by outside
data providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

                    Annual Report

                    October 31, 2005


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.
At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/s/ CHRISTOPHER O. BLUNT

PRINCIPAL VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE
OR LESS THAN THEIR ORIGINAL COST. FOR CURRENT TO THE MOST RECENT MONTH-END
PERFORMANCE INFORMATION, PLEASE CALL 1-800-MAINSTAY (1-800-624-6782) OR VISIT

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee, and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Performance figures reflect
certain fee waivers and/or expense limitations, without which total returns may
have been lower. The fee waivers and/or expense limitations are contractual and
may be modified or terminated only with the approval of the Board of Trustees.
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
8/31/98, performance of Class I shares (first offered 12/28/04) 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.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY COMMON STOCK FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Harvey Fram, CFA, of New York Life
Investment Management LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invest at least 80% of its assets in common stocks. We seek to
identify companies that are considered to have a high probability of
outperforming the S&P 500(R) Index(1) over the following six to twelve months.
Our underlying stock-selection process is based on a quantitative process that
ranks stocks based on traditional value measures, earnings quality, and
technical factors. These stocks are then generally held in larger or smaller
proportions based on their relative attractiveness. On occasion, trading
strategies that seek to realize returns over shorter periods may be employed.
The Fund normally invests in common stocks of well-established U.S. companies,
primarily those with large capitalizations. The Fund is managed with a core
orientation (including both growth and value equities). We use a bottom-up
approach that assesses stocks based on their individual strengths, rather than
focusing on the underlying sectors or industries of those stocks or on general
economic trends. We may sell a security if we no longer believe it will
contribute to meeting the investment objective of the Fund.

WHAT WERE THE MAJOR FACTORS AFFECTING THE STOCK MARKET DURING THE 12 MONTHS
ENDED OCTOBER 31, 2005?

For the 12 months ended October 31, 2005, all broadly watched equity indices
provided positive performance. Mid- and small-capitalization stocks generally
outperformed their large-cap counterparts. The market favored value stocks over
growth stocks at all capitalization levels. Despite wide fluctuations in
crude-oil prices, instability in many regions of the world, and the devastation
caused by hurricanes Katrina and Rita, the U.S. stock market posted significant
gains during the 12 months ended October 31, 2005.

The Federal Open Market Committee continued to raise its target for the federal
funds rate, with eight 25-basis-point increases during the reporting period. (A
basis point is one-hundredth of a percentage point.) At the end of October 2005,
the target rate stood at 3.75%, its highest level in more than four years. Among
the considerations that influenced the gradual tightening policy were mounting
inflationary pressures, low unemployment, an upward path of record energy
prices, and growing labor costs.

WERE THERE ANY CHANGES IN THE FUND'S POSITIONING OR MANAGEMENT DURING THE
REPORTING PERIOD?

MainStay Common Stock Fund uses a quantitative model. There were minor
adjustments to the model during the reporting period. We added a "change in
shares outstanding" factor and an "industry relative price to cash flow" factor.
The Fund has maintained a fairly neutral positioning during the reporting
period, with a projected beta very close to one.(2)

HOW WAS THE FUND ALLOCATED RELATIVE TO THE S&P 500(R) INDEX DURING THE REPORTING
PERIOD?

During the 12 months ended October 31, 2005, the Fund was overweighted relative
to the S&P 500(R) Index in the utilities, energy, information technology,
financials, and telecommunication services sectors. During the reporting period,
the Fund was under-weighted relative to the Index in the consumer staples,
industrials, consumer discretionary, materials, and health care sectors.

WHICH SECTORS AND INDIVIDUAL STOCKS MADE THE MOST SUBSTANTIAL POSITIVE
CONTRIBUTIONS TO THE FUND'S PERFORMANCE DURING THE 12-MONTH REPORTING PERIOD?

The Fund's five strongest-performing sectors were energy, financials, health
care, utilities, and consumer staples.

Among individual stocks, the strongest contributors to the Fund's performance
were ConocoPhillips, an integrated global energy company that continued to post
high earnings; UnitedHealth Group, a health care service provider that increased
earnings, lowered costs, and achieved higher membership; and the parent company
of Philip Morris and Kraft Foods, Altria Group, which benefited from optimism
over favorable court rulings.

WHICH SECTORS AND INDIVIDUAL STOCKS DETRACTED FROM THE FUND'S PERFORMANCE?

The Fund's five weakest-performing sectors during the 12-month reporting period
were telecommunication services, consumer discretionary, materials, industrials,
and information technology.


1. See footnote on page 4 for more information on the S&P 500(R) Index.
2. Beta is a measure of the volatility of a stock in relation to the market as a
   whole. The S&P 500(R) Index has a beta of one. Stocks with a higher beta tend
   to be more volatile than the market. Stocks with a lower beta tend to rise
   and fall more slowly than the market.

                                                     www.MAINSTAYfunds.com     7


Among individual stocks, the weakest contributors to the Fund's performance were
Pfizer, a pharmaceutical company whose shares fell on negative news about
Celebrex; Fannie Mae, a government-sponsored mortgage provider that experienced
accounting problems; and Verizon Communications, a communication services
provider. Verizon Communications' shares declined when competitor Sprint merged
with Nextel Communications.

WERE THERE ANY SIGNIFICANT EQUITY PURCHASES OR SALES DURING THE REPORTING
PERIOD?

The Fund uses a quantitative model whose major inputs include
price-to-cash-flow, earnings trends, earnings quality, and price trends. A
combination of these factors may be used in determining additions to the Fund's
portfolio. In some instances, stocks are included in the Fund for
diversification and risk-control purposes even if they score poorly in the
model.

From November 2004 through July 2005, the Fund established a position in Vertex
Pharmaceuticals, a biotechnology company whose stock advanced when the company
announced that it would be streamlining its developmental pipeline. SanDisk
Corp. was purchased for the Fund in August 2005. The company, which designs,
develops, and markets flash-storage card products used in consumer electronics,
benefited from continued strong demand. From December 2004 through June 2005,
the Fund established a position in Murphy Oil. This holding company, which
engages in the exploration, production, refining, and marketing of oil and gas,
nearly doubled its profit because of higher energy prices.

We sold the Fund's entire positions in Delta Air Lines, Toys "R" Us, and Storage
Technology during the reporting period. Toys "R" Us and Storage Technology were
sold at a profit, but Delta Air Lines was sold at a loss. Delta Air Lines
struggled with increased competition and higher fuel prices. Toys "R" Us, which
sells toys, children's apparel, and baby products, had its stock bought out by a
private equity partnership. Storage Technology, a leading storage company, was
sold when our quantitative model indicated that its shares had become
overvalued.

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 Common
Stock Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Distribution of Class A shares
and Class B shares commenced on June 1, 1998. Class C shares were initially
offered on September 1, 1998. Distribution of Class I shares commenced on
December 28, 2004. Class A shares are offered at net asset value per share plus
an initial sales charge. No sales charge applies on investments of $1 million or
more (and certain other qualified purchases) in Class A shares, but a contingent
deferred sales charge is imposed on certain redemptions of such shares within
one year of the date of purchase. Class B shares and Class C shares are offered
without an initial sales charge, although a declining contingent deferred sales
charge may be imposed on redemptions made within six years of purchase of Class
B shares and within one year of purchase of Class C shares. Class I shares are
not subject to sales charge. Class A shares, Class B shares, Class C shares and
Class I shares bear the same voting (except for issues that relate solely to one
class), dividend, liquidation and other rights and conditions. Each class of
shares other than Class I shares bears distribution and/or service fee payments
under a distribution plan pursuant to Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to seek long-term growth of capital, with
income as a secondary consideration.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on the valuation date; such securities not
traded on the valuation date are valued at the mean of the latest quoted bid and
asked prices. Prices normally are taken from the principal market in which each
security trades. Temporary cash investments acquired over 60 days to maturity
are valued using the latest bid prices or using valuations based on a matrix
system (which considers such factors as security prices, yields, maturities, and
ratings), both as furnished by independent pricing services. Other temporary
cash investments are valued at amortized cost, which approximates market value.
Securities for which market quotations are not readily available are valued by
methods deemed in good faith by Board of Trustees to represent fair value.
Reasons for which securities may be valued in this manner include, but are not
limited to, trading for a security has been halted or suspended, a security has
been de-listed from a national exchange, or trading on a security's principal
market is temporarily closed at a time when under normal conditions it would be
open. The Fund did not hold securities at October 31, 2005, that were valued in
such manner.

(B) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See note 7)

(C) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are withheld at the source.

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
quarterly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

 22   MainStay Common Stock Fund


The following table discloses the current period reclassification between
undistributed net investment income, accumulated net realized loss on
investments and additional paid-in capital arising from permanent differences;
net assets at October 31, 2005, are not affected.

<Table>
<Caption>
                        ACCUMULATED
     UNDISTRIBUTED     NET REALIZED
    NET INVESTMENT          LOSS ON        ADDITIONAL
            INCOME      INVESTMENTS   PAID-IN-CAPITAL
                                
    $         (380)  $        4,770   $        (4,390)
</Table>

The reclassifications for the Fund are primarily due to the fact that net
operating losses cannot be carried forward for federal income tax purposes and
real estate investment trusts investments.

(E) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on short-term securities are accreted and amortized,
respectively, on the straight line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(G) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(H) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER.  New York Life Investment Management LLC ("NYLIM" or the
"Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's Manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. The Fund
is advised by the Manager directly, without a Subadvisor.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.70% on assets up to $500 million and
0.65% on assets in excess of $500 million. Effective August 1, 2005, the Manager
has entered into a written expense limitation agreement, under which the Manager
has agreed to reimburse the expenses of the Fund so that the total operating
expenses (excluding taxes, interest, litigation, extraordinary expenses, and
brokerage and other transaction expenses relating to the purchase or sale of
portfolio investments) do not exceed, on an annualized basis, 1.30% of the
average daily net assets of the Class A shares. An equivalent reimbursement, in
an equal amount of basis points, will be applied to the other share classes. The
Manager, within three years of incurring such expenses, may recoup the amount of
any management fee waiver or expense reimbursement from the Fund pursuant to
this agreement if such recoupment does not cause the Fund to exceed the expense
limitations. At October 31, 2005, the Fund had $124,534 of recoupment available.
This amount is available until October 31, 2008. This expense limitation may be
modified or terminated only with the approval of the Board of Trustees. Prior to
August 1, 2005 and after December 1, 2004, the Manager had agreed to reimburse
the expenses of the Fund so that total operating expenses would not exceed, on
an annualized basis, 1.38% of the average daily net assets of the Class A
shares, and such that there would be an equivalent reduction for the other
classes of shares. Prior to December 1, 2004, the Manager voluntarily agreed to
reimburse the expenses of the Fund so that operating expenses would not exceed
on an annualized basis 1.65%, 2.40%, and 2.40% of average daily net assets of
the Class A, Class B, and Class C shares, respectively. For the year ended
October 31, 2005, the Manager earned fees from the

                                                    www.MAINSTAYfunds.com     23

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

Fund in the amount of $904,732, and waived its fees and/or reimbursed expenses
in the amount of $435,191.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from
the Fund at an annual rate of 0.25% of the average daily net assets of the
Fund's Class A shares, which is an expense of the Class A shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The Plans provide that the Class B and Class C shares of the Fund also
incur a service fee at the annual rate of 0.25% of the average daily net asset
value of the Class B or Class C shares of the Fund. Class I shares are not
subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $13,578 for the year ended
October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $1,495, $77,935 and $579, respectively, for the year ended October 31,
2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund for the year ended
October 31, 2005, amounted to $537,805.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus the Fund only pays a
portion of the fees identified above.

(F) CAPITAL.  At October 31, 2005, New York Life and its affiliates held shares
of Class A with a net value of $12,313,969. This represents 34.3% of Class A
shares net assets and 7.7% of the Funds total net assets at period end.

(G) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$3,537 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $39,591 for the year ended
October 31, 2005.

NOTE 4 -- CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, The Bank of New York acted as custodian for the Fund.

NOTE 5 -- FEDERAL INCOME TAX:

As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis

of $13,718,729 were available as shown in the table below, to the extent
provided by the regulations to offset future realized gains of the Fund through
the years indicated. To the extent that these loss

carryforwards are used to offset future capital gains, it is probable that the
capital gains so offset will not be distributed to shareholders.

NOTE 10 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to agreements with certain registered
representatives of broker-dealers relating to the level of trading by clients of
those registered representatives in shares of certain funds of the Trust. All
such arrangements were terminated by the fourth quarter of 2003. NYLIM and the
Trustees of the Trust have reviewed the possible dilutive effects that
transactions under those arrangements and certain other levels of trading by
fund shareholders over the period from 1999 to 2003 may have had on the funds.
As a result of this review in December 2005, NYLIM made payments totaling $5.9
million to nine MainStay funds. No payment was made with respect to the MainStay
Common Stock Fund. NYLIM has also agreed to reimburse or pay all expenses
relating to the Board of Trustees' review of this matter and has paid
substantially all of the costs associated with the other regulatory matters
described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Common Stock Fund ("the Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2005, and
the related statement of operations for the year then ended, and the statements
of changes in net assets and financial highlights for each of the years in the
two-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Common Stock Fund of The MainStay Funds as of October 31, 2005, the
results of its operations for the year then ended, and the changes in its net
assets and financial highlights for each of the years in the two-year period
then ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement, the Board of
Trustees requested and received from the Manager, and reviewed, a wide variety
of information. The Trustees also requested and received information from
outside data providers and information and analysis from a third party
consultant. The Trustees considered various industry and regulatory trends in
their deliberations. In considering approval of the Agreement, and in evaluating
the fairness of the compensation to be paid by the Fund, the Trustees met a
number of times as a full Board and in executive sessions of only the Non-
Interested Trustees to discuss the Board's consideration of the approval of the
Agreement, and took into account a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager. The Trustees reviewed the services that the Manager has
provided historically to the Fund, and also generally to other series of the
Trust. The Manager's services to the Trust have included investment management
services, including the day-to-day management of the portfolio and the selection
and supervision of portfolio managers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Trustees considered, among other things, the Manager's management, personnel,
resources, operations and portfolio management capabilities. In considering the
Manager's practices relating to best execution of portfolio trades, the Board
reviewed reports of the Fund's Brokerage Committee including with respect to
analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager and certain other service providers. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager were such that, in the context of the Board's overall review of various
factors, the Management Agreement should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's recent performance that was
slightly better than mid-range of funds determined to be comparable to the Fund
and the Fund's underperformance over a longer time period relative to the
average of a grouping of funds having similar investment objectives.

The Trustees considered the cost to the Manager of the Agreement and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees noted the Manager's
agreement to limit the Fund's net expenses to a certain level with respect to
the Fund, with the expectation that the Manager intended, over time, to
implement measures designed to reduce the Trust's transfer agency fees. The
Trustees considered certain benefits expected for, and risks borne by, the
Manager and its affiliates, including benefits from soft dollar arrangements.
The Trustees considered the services provided to the Fund by affiliates of the
Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the
benefits to the Manager and its affiliates from those relationships. The
information provided to the Trustees indicated that the profitability to the
Manager and its affiliates arising directly from those other agreements was not
excessive. The Trustees acknowledged certain benefits to the reputation of the
Manager and its affiliates, as well to that of the Trust, from their association
with each other.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund grows, or as the Trust grows overall,
noting in particular the Manager's plans for marketing and distributing shares
of various series of the Trust. They noted the Manager's willingness to
implement contractual breakpoints, and that the contractual breakpoints in place
for the management fee were intended to provide that the Fund's shareholders
would share in benefits from economies of scale arising from the growth of Fund
assets. The Trustees acknowledged that the Fund had not yet reached

 30   MainStay Common Stock Fund


the asset level at which breakpoints would reduce the contractual management fee
to which the Fund is subject. Acknowledging the difficulty of forecasting
economies of scale, the Trustees generally expressed an intention to monitor the
Manager's profitability and consider the application of fee breakpoints or other
appropriate measures as the Board may determine from time to time. The Trustees
reviewed historical information about changes in the Fund's expense and asset
levels over time, as well as information about certain Fund expenses that would
remain fixed even as Fund assets increase and, therefore, provide the Fund with
benefits from economies of scale as the Fund grows. The Trustees noted that, to
the extent the Fund's gross expenses currently are higher than its net expenses,
economies of scale achieved through an increase in the Fund's assets might not
directly benefit the Fund through lower net expenses. The Trustees considered
various information about transfer agency expenses, including information
showing that transfer agency fees of the Fund and a significant number of series
of the Trust (although not every such series or with respect to every share
class of each series) tended to be high, when aggregated and expressed as a
percentage of the assets of certain series, compared to the mutual fund industry
average according to certain studies reviewed by the Board and, therefore,
adversely affected gross expense ratios. The Board received information about
potential effects on the Manager were it to subsidize certain portions of the
Trust's transfer agency fees. The Trustees noted that a significant number of
shareholders of the Trust's series had small amounts invested in the series, and
have considered measures intended to increase average shareholder account size
and/or otherwise reduce the Trust's transfer agency fees and expenses, including
steps that the Manager has taken to encourage shareholders to consolidate or
close small accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager, including other registered funds and separate
institutional accounts, that had investment objectives similar to that of the
Fund. The Trustees took into account information provided by the Manager about
the relative scope of services provided to the Fund and to those accounts or
explanations about the accounts' histories. In considering the extent of the
fees received by the Manager for providing services to the Fund, the Trustees
evaluated factors such as the fees and expenses borne by other registered funds
in the market pursuing strategies generally similar to those followed by the
Fund. The Trustees considered the Fund's historical and proposed contractual and
net management fees, its anticipated gross and net expense ratios, and various
components of that expense ratio, in comparison to other funds in comparison
groupings prepared by outside data providers using objective methodologies.

The Trustees acknowledged the historical relationship between the Manager and
the Trust and the likely difficulties in implementing an alternative to the
investment management arrangement between them. The Trustees also took account
of the results of their various discussions with the Manager concerning the
levels of the Fund's contractual and net management fees and the Fund's
anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreement. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreement.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreement, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of this Agreement was in the best
interests of the Fund and its shareholders.

 2   MainStay Small Cap Growth Fund


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.
At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/s/ Christopher O. Blunt

Christopher O. Blunt
President

THAN THEIR ORIGINAL COST. FOR CURRENT TO THE MOST RECENT MONTH-END PERFORMANCE
INFORMATION, PLEASE CALL 1-800-MAINSTAY (1-800-624-6782) OR VISIT

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY SMALL CAP GROWTH FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Rudolph C. Carryl and Edmund C. Spelman
of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in companies with market
capitalizations at the time of investment comparable to those of companies in
the Russell 2000(R) Index.(1) We select investments according to the economic
environment, the attractiveness of particular markets, and the financial
condition and competitiveness of individual companies. In implementing this
strategy, we look for securities of companies with above-average revenue and
earnings-per-share growth, participation in growing markets, potential for
positive earnings surprises, and strong management. Ideally, the companies will
have high levels of ownership by insiders. We may also invest in companies that
we believe are attractive because of special factors, such as new management,
new products, changes in consumer demand, or changes in the economy. We may sell
a stock if the stock's earnings growth rate decelerates, if its valuation is
deemed too high in relation to its growth rate or its peer group, or if we no
longer believe that the security will help the Fund meet its investment
objective.

WHAT MAJOR FACTORS INFLUENCED STOCK-MARKET PERFORMANCE DURING THE 12 MONTHS
ENDED OCTOBER 31, 2005?

Among the most significant factors that influenced the equity markets during the
reporting period were Federal Reserve interest-rate hikes, high energy prices,
rising inflation, and the apparent slowdown in the rate of corporate earnings
growth and economic advancement. An influx of hurricanes in the late summer and
early fall took a toll not only on the Gulf states but also on the overall
market.

WHAT SECTORS HAD THE GREATEST IMPACT ON THE FUND'S RELATIVE PERFORMANCE DURING
THE REPORTING PERIOD?

The Fund's performance was helped most by favor-able stock selection in the
consumer discretionary sector. The Fund's holdings in this sector outperformed
related stocks in the Russell 2000(R) Growth Index.(2) An overweighted position
in the energy sector and an underweighted position in the information technology
sector also helped the Fund's results. The Fund's stock selection in the
information technology and health care sectors, however, detracted from
performance.

For the 12 months ended October 31, 2005, we maintained the Fund's overweighted
position in the consumer discretionary sector. Our decision to do so had a
positive effect on the Fund's performance. Our decision to increase the Fund's
weighting among energy stocks also strengthened the Fund's returns.

WHAT WERE SOME OF THE FUND'S STOCK-SPECIFIC SUCCESS STORIES?

Cal Dive International was the strongest positive contributor to the Fund's
performance. With operations in the Gulf of Mexico, this energy services company
benefited from higher energy prices and continued strong demand. Coldwater
Creek, originally a catalog and mail order house, advanced on rapid expansion of
the company's retail store chain. Shares of Arch Coal, a company that mines,
processes, and markets low-sulfur coal, rose steadily throughout the reporting
period because of higher energy prices
and growing global demand. Ryland Group is a homebuilder that benefited from
continued strong demand and industry consolidation. Shares of Sierra Health
Services, a Las Vegas-based managed health care organization, rose with
commercial enrollment-driven earnings growth because of the company's dominant
market presence in Nevada.

WHICH STOCKS DETRACTED FROM THE FUND'S RESULTS?

Several of the Fund's holdings failed to meet our expectations. Sigmatel is a
semiconductor company that supplies memory chips for Apple iPod Shuffles. The
company's stock dropped sharply in October 2005 because of faster-than-expected
product transition. PETCO Animal Supplies--a retailer of pet food, supplies, and
services--was hurt by reduced store traffic and by a shift in marketing strategy
that failed to generate anticipated sales. Trex manufactures and distributes
wood/plastic composite products primarily for residential and commercial decking
and railing. Trex had a rough 12-month period because of lower-than-expected
volume, which stemmed from excess inventory among dealers and from significant
increases in the price of raw materials. Bradley Pharmaceuticals, a specialty
phar-


Stocks of small companies may be subject to higher price volatility,
significantly lower trading volumes, and greater spreads between bid and ask
prices than stocks of larger companies. Small companies may be more vulnerable
to adverse business or market devel- opments than mid- or large-capitalization
companies. The Fund may experience a portfolio turnover rate of over 100% and
may generate short-term capital gains which are taxable.

maceutical company, suffered a sharp stock-price decline when the company
announced that its accounting practices would be investigated by the Securities
and Exchange Commission. Innovative Solutions & Support--a company that designs,
manufactures, and sells flight-information computers, flat-panel displays, and
monitoring systems--reported disappointing first-quarter 2005 results. We sold
the Fund's positions in Sigmatel, Trex, and Bradley Pharmaceuticals during the
reporting period.

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD?

Since energy prices remained high, we added Grant Prideco to the Fund. The
company produces oil-field drill pipe and other products and services used in
drilling for oil and gas. We also established a Fund position in James River
Coal, which engages in mining, processing, and selling coal in eastern Kentucky.
We initiated a Fund position in Electronic Boutiques Holdings, which recently
merged with GameStop to form a leading global retailer of video-game and
entertainment software. We believe that the merger may help the company enter
new international markets and compete more effectively in the highly competitive
U.S. video-game industry. In the consumer discretionary sector, we added
Children's Place, a retailer of children's apparel and accessories that recently
acquired the Disney Store chain. Earnings at The Children's Place Retail Stores
are expected to benefit from acquisition-related synergies and cost reductions.
We also established a Fund position in Jos. A. Bank Clothiers, which designs,
retails, and markets men's tailored and casual clothing and men's accessories in
the United States.

WHICH STOCKS DID THE FUND SELL DURING THE REPORTING PERIOD?

In addition to the sales we've already mentioned, the Fund eliminated its
holdings in Bluegreen and Corinthian Colleges during the reporting period.
Bluegreen offers timeshare vacation properties and builds residential
communities. The company experienced a sharp stock-price correction when it
reported disappointing earnings because of higher-than-expected costs and
lower-than-expected sales. We sold the Fund's position in Corinthian Colleges
because of disappointing earnings results and concerns about government
investigations into the industry's marketing practices.

DID THE FUND CHANGE ITS SECTOR WEIGHTINGS DURING THE REPORTING PERIOD?

From October 31, 2004, to October 31, 2005, we substantially increased the
Fund's weighting in the energy sector. We also increased the Fund's weighting
among industrial stocks. During the reporting period, the Fund decreased its
weightings in the consumer discretionary, health care, and information
technology sectors.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

As of October 31, 2005, the Fund was overweighted relative to the Russell
2000(R) Growth Index in the consumer discretionary, energy, and industrial
sectors. On the same date, the Fund held under-weighted positions in the
consumer staples, health care, materials, and information technology sectors. At
the end of the period, the Fund had no holdings in the telecommunication
services or utilities sectors.

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 Small Cap
Growth Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares. Distribution of Class A
shares and Class B shares commenced on June 1, 1998. Class C shares were
initially offered on September 1, 1998. Class A shares are offered at net asset
value per share plus an initial sales charge. No sales charge applies on
investments of $1 million or more (and certain other qualified purchases) in
Class A shares, but a contingent deferred sales charge is imposed on certain
redemptions of such shares within one year of the date of purchase. Class B
shares and Class C shares are offered without an initial sales charge, although
a declining contingent deferred sales charge may be imposed on redemptions made
within six years of purchase of Class B shares and within one year of purchase
of Class C shares. Class A shares, Class B and Class C shares bear the same
voting (except for issues that relate solely to one class), dividend,
liquidation and other rights and conditions except that the Class B shares and
Class C shares are subject to higher distribution fee rates. Each class of
shares bears distribution and/or service fee payments under a distribution plan
pursuant to Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to seek long term-capital appreciation by
investing primarily in securities of small-cap companies.

Small-capitalization companies may be more volatile in price and have
significantly lower trading volumes than companies with larger capitalizations.
They may be more vulnerable to adverse business or market developments than
larger-capitalization companies.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on the valuation date; such securities not
traded on the valuation date are valued at the mean of the latest quoted bid and
asked prices. Prices normally are taken from the principal market in which each
security trades. Temporary cash investments acquired over 60 days to maturity
are valued using the latest bid prices or using valuations based on a matrix
system (which considers such factors as security prices, yields, maturities, and
ratings), both as furnished by independent pricing services. Other temporary
cash investments are valued at amortized cost, which approximates market value.
Securities for which market quotations are not readily available are valued by
methods deemed in good faith by Board of Trustees to represent fair value.
Reasons for which securities may be valued in this manner include, but are not
limited to, trading for a security has been halted or suspended, a security has
been de-listed from a national exchange, or trading on a security's principal
market is temporarily closed at a time when under normal conditions it would be
open. The Fund did not hold securities at October 31, 2005, that were valued in
such manner.

(B) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (see Note 7.)

(C) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are withheld at the source.

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
quarterly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

The following table discloses the current year reclassifications between
accumulated net investment loss and

 18   MainStay Small Cap Growth Fund


additional paid-in-capital arising from permanent differences; net assets at
October 31, 2005, are not affected.

<Table>
<Caption>
                         ADDITIONAL
NET INVESTMENT LOSS    PAID-IN-CAPITAL
                    
     $3,979,978         $(3,979,978)
</Table>

The reclassification for the Fund is due to the fact that net operating losses
cannot be carried forward for federal income tax purposes.

(E) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on short-term securities are accreted and amortized,
respectively, on the straight line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(G) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(H) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 1.00% on assets up to $1.0 billion and
0.95% on assets in excess of $1.0 billion. NYLIM agrees to voluntarily waive its
management fee by 0.15% to 0.85%. Effective August 1, 2005, the Manager has
entered into a written expense limitation agreement, under which the Manager has
agreed to reimburse the expenses of the Fund so that the total operating
expenses (excluding taxes, interest, litigation, extraordinary expenses, and
brokerage and other transaction expenses relating to the purchase or sale of
portfolio investments) do not exceed, on an annualized basis, 1.48% of the
average daily net assets of the Class A shares. An equivalent reimbursement, in
an equal amount of basis points, will be applied to the other share classes. The
Manager, within three years of incurring such expenses, may recoup the amount of
any management fee waiver or expense reimbursement from the Fund pursuant to
this agreement if such recoupment does not cause the Fund to exceed the expense
limitations. There were no amounts available for recoupment at October 31, 2005.
This expense limitation may be modified or terminated only with the approval of
the Board of Trustees. Prior to August 1, 2005 and after December 1, 2004, NYLIM
agreed to voluntarily reimburse the expenses of the Fund so that the total
operating expenses would not exceed on an annualized basis 1.70% of the average
daily net assets of the Class A shares, and such that there would be an
equivalent reduction for the other classes of shares. For the year ended October
31, 2005, the manager earned fees from the Fund in the amount of $2,545,742 and
waived its fees and/or reimbursed expenses in the amount of $731,987.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of
0.50% of the average daily net assets of the Fund. To the extent the

                                                    www.MAINSTAYfunds.com     19

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

Manager has agreed to reimburse expenses of the Fund, the Subadvisor has
voluntarily agreed to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, has adopted distribution plans (the "Plans") in accordance
with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A
Plan, the Distributor receives a monthly fee from the Fund at an annual rate of
0.25% of the average daily net assets of the Fund's Class A shares, which is an
expense of the Class A shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly fee, which is an expense of the Class B and
Class C shares of the Fund, at the annual rate of 0.75% of the average daily net
assets of the Fund's Class B and Class C shares. The Plans provide that the
Class B and Class C shares of the Fund also incur a service fee at the annual
rate of 0.25% of the average daily net asset value of the Class B or Class C
shares of the Fund. The Plans provide that the distribution and service fees are
payable to the Distributor regardless of the amounts actually expended by the
Distributor for distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $42,687 for the year ended
October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $5,693, $245,716 and $855, respectively, for the year ended October
31, 2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund for the year ended
October 31, 2005, amounted to $1,392,375.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus the Fund only pays a
portion of the fees identified above.

(F) CAPITAL.  At October 31, 2005, New York Life held shares of Class A with a
net asset value of $5,221,338. This represents 7.5% of the Class A shares net
assets and 2.2% of the Fund's total net assets at October 31, 2005.

(G) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$6,605 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $52,124 for the year ended
October 31, 2005.

NOTE 4 -- CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, The Bank of New York acted as custodian for the Fund.

NOTE 5 -- FEDERAL INCOME TAX:

As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis
were as follows:

<Table>
<Caption>
ACCUMULATED CAPITAL     UNREALIZED    TOTAL ACCUMULATED
  AND OTHER LOSSES     APPRECIATION         LOSS
                                

   $(151,508,855)      $50,129,652     $(101,379,203)
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sales deferrals.

At October 31, 2005, for federal income tax purposes, capital loss carryforwards
of $151,508,855 were available as shown in the table below, to the extent
provided by the regulations to offset future realized gains of the Fund through
the years indicated. To the extent that these loss carryforwards are used to
offset future capital gains, it is

 20   MainStay Small Cap Growth Fund


probable that the capital gains so offset will not be distributed to
shareholders.

investments in accordance with the Fund's securities lending procedures.
Pursuant to Rule 2a-7, securities purchased with collateral received are valued
at amortized cost.

NOTE 8 -- LINE OF CREDIT:

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

NOTE 10 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those arrangements and certain other levels of trading
by fund shareholders over the period from 1999 to 2003 may have had on the
funds. As a result of this review in December 2005, NYLIM made payments totaling
$5.9 million to nine MainStay funds. The amount paid to the MainStay Small Cap
Growth Fund was $38,000. NYLIM has also agreed to reimburse or pay all expenses
relating to the Board of Trustees' review of this matter and has paid
substantially all of the costs associated with the other regulatory matters
described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Small Cap Growth ("the Fund"), one
of the funds constituting The MainStay Funds, as of October 31, 2005, and the
related statement of operations for the year then ended, and the statements of
changes in net assets and financial highlights for each of the years in the
two-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Small Cap Growth Fund of The MainStay Funds as of October 31, 2005, the
results of its operations for the year then ended, and the changes in its net
assets and financial highlights for each of the years in the two-year period
then ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreement, the Board of Trustees requested and received from the
Manager and Subadvisor, and reviewed, a wide variety of information. The
Trustees also requested and received information from outside data providers and
information and analysis from a third party consultant. The Trustees considered
various industry and regulatory trends in their deliberations. In considering
approval of these Agreements, and in evaluating the fairness of the compensation
to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and Subadvisor have provided historically to the Fund, and also
generally to other series of the Trust. The Manager's services to the Trust have
included investment management services, including the selection and supervision
of portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the
day-to-day management of the portfolio, providing reports to the Manager, and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. In considering the Manager's
and Subadvisor's practices relating to best execution of portfolio trades, the
Board reviewed reports of the Fund's Brokerage Committee including with respect
to analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager, the Subadvisor and certain other service
providers, as well as the Subadvisor's attention to its compliance program. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager and Subadvisor were such that, in the context of the Board's overall
review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's underperformance when compared
over several time periods with funds concluded by Trustees to be peers of the
Fund.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees noted the Manager's
agreement to limit the Fund's net expenses to a certain level with respect to
the Fund, with the expectation that the Manager intended, over time, to
implement measures designed to reduce the Trust's transfer agency fees. The
Trustees considered certain benefits expected for, and risks borne by, the
Manager and its affiliates, including benefits from soft dollar arrangements.
The Trustees considered the services provided to the Fund by affiliates of the
Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the
benefits to the Manager and its affiliates from those relationships. The
information provided to the Trustees indicated that the profitability to the
Manager and its affiliates arising directly from those other agreements was not
excessive. The Trustees acknowledged certain benefits to the reputation of the
Manager and its affiliates, as well to that of the Trust, from their association
with each other.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund grows, or as the Trust grows overall,
noting in particular the Manager's plans for marketing and distributing shares
of various series of the Trust. They noted the Manager's willingness to
implement contractual

 26   MainStay Small Cap Growth Fund


breakpoints, and that the contractual breakpoints in place for the management
fee were intended to provide that the Fund's shareholders would share in
benefits from economies of scale arising from the growth of Fund assets. The
Trustees acknowledged that the Fund had not yet reached the asset level at which
breakpoints would reduce the contractual management fee to which the Fund is
subject. Acknowledging the difficulty of forecasting economies of scale, the
Trustees generally expressed an intention to monitor the Manager's profitability
and consider the application of fee breakpoints or other appropriate measures as
the Board may determine from time to time. The Trustees reviewed historical
information about changes in the Fund's expense and asset levels over time, as
well as information about certain Fund expenses that would remain fixed even as
Fund assets increase and, therefore, provide the Fund with benefits from
economies of scale as the Fund grows. The Trustees noted that, to the extent the
Fund's gross expenses currently are higher than its net expenses, economies of
scale achieved through an increase in the Fund's assets might not directly
benefit the Fund through lower net expenses. The Trustees considered various
information about transfer agency expenses, including information showing that
transfer agency fees of the Fund were among the highest of the series of the
Trust, and also that transfer agency fees of a significant number of series of
the Trust (although not every such series or with respect to every share class
of each series) tended to be high, when aggregated and expressed as a percentage
of the assets of certain series, compared to the mutual fund industry average
according to certain studies reviewed by the Board and, therefore, adversely
affected gross expense ratios. The Board received information about potential
effects on the Manager were it to subsidize certain portions of the Trust's
transfer agency fees. The Trustees noted that a significant number of
shareholders of the Trust's series had small amounts invested in the series, and
have considered measures intended to increase average shareholder account size
and/or otherwise reduce the Trust's transfer agency fees and expenses, including
steps that the Manager has taken to encourage shareholders to consolidate or
close small accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts, that had investment objectives similar to
that of the Fund. The Trustees took into account information provided by the
Manager or Subadvisor about the relative scope of services provided to the Fund
and to those accounts or explanations about the accounts' histories. In
considering the extent of the fees received by the Manager and Subadvisor for
providing services to the Fund, the Trustees evaluated factors such as the fees
and expenses borne by other registered funds in the market pursuing strategies
generally similar to those followed by the Fund. The Trustees considered the
Fund's historical and proposed contractual and net management fees, its
anticipated gross and net expense ratios, and various components of that expense
ratio, in comparison to other funds in comparison groupings prepared by outside
data providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

 2   MainStay Small Cap Value Fund


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.

At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/s/ CHRISTOPHER O. BLUNT


Christopher O. Blunt
President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and max-imum applicable sales charges explained in this
paragraph. The graphs assume an initial investment of $10,000 and reflect the
deduction of all sales charges that would have applied for the period of
investment. Class A shares are sold with a maximum initial sales charge of 5.5%
and an annual 12b-1 fee of .25%. Class B shares are sold with no initial sales
charge, are subject to a contingent deferred sales charge (CDSC) of up to 5% if
redeemed within the first six years of purchase, and have an annual 12b-1 fee of
1.00%. Class C shares are sold with no initial sales charge, are subject to a
CDSC of 1% if redeemed within one year of purchase, and have an annual 12b-1 fee
of 1.00%. Class I shares are sold with no initial sales charge or CDSC, have no
annual 12b-1 fee, and are generally available to corporate and institutional
investors with a minimum initial investment of $5 million. Performance figures
reflect certain fee waivers and/or expense limitations, without which total
returns may have been lower. The fee waivers and/or expense limitations are
contractual and may be modified or terminated only with the approval of the
Board of Trustees. From inception (6/1/98) through 8/31/98, performance for
Class C shares (first offered 9/1/98) includes the historical performance of
Class B shares adjusted to reflect the applicable CDSC for Class C shares. From
inception through 2/15/05, performance of Class I shares (first offered 2/16/05)
includes the historical performance of Class A shares adjusted to reflect the
applicable sales charge (or CDSC) and fees and expenses for Class I shares.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY SMALL CAP VALUE FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Caroline Evascu of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in companies with market
capitalizations at the time of investment comparable to companies in the Russell
2000(R) Value Index(1) and invests primarily in common stocks and securities
convertible into common stock. In implementing this strategy, we use an
investment selection process that focuses on stocks that meet three criteria:
inexpensive valuations, free cash flow, and multiple sources of potential growth
or earnings. We look for stocks that are inexpensive relative to the Russell
benchmark, their peer group, or historical valuations. We take a long-term
approach to investing and rely primarily on our proprietary fundamental
research. The portfolio is constructed using a bottom-up stock selection
process. Stocks will be sold when they meet our price objective or when we
believe there is a negative change in the fundamental performance of the issuer.

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED
OCTOBER 31, 2005?

The stock market reacted to concerns about the potential impact of higher energy
prices and rising interest rates on consumer spending. According to Russell
data, mid-capitalization stocks showed the strongest performance during the
12-month reporting period, followed by small-caps, and then large-cap stocks.
From a style perspective, value stocks outperformed growth stocks at all
capitalization levels. In the Russell 2000(R) Value Index, the consumer
discretionary sector sold off more than 4% during the third calendar quarter of
2005 and continued to be weak as the market reacted to fears of a slowdown in
consumer spending, exacerbated by hurricanes Katrina and Rita.

WHAT FACTORS HAD A SIGNIFICANT IMPACT ON THE FUND'S PERFORMANCE DURING THE
REPORTING PERIOD?

Excluding all sales charges, all share classes of the Fund underperformed the
Russell 2000(R) Value Index during the 12-month reporting period. The Fund's
overweighted positions in consumer discretionary and information technology, the
two worst-performing sectors in the Index, were partly to blame. During the
reporting period, we increased the Fund's position in Graftech International to
place it among the Fund's largest holdings. Since this stock showed particularly
weak performance, however, it detracted from the Fund's results during the
reporting period.

WHICH OF THE FUND'S HOLDINGS WERE STRONG PERFORMERS DURING THE REPORTING PERIOD?

Parker Drilling, an oil and gas contract drilling company, provided strong
performance during the period, reflecting positive fundamentals in the energy
sector. The company also sold several of its assets and used the proceeds to
improve its balance sheet, putting the company on a much stronger financial
footing. Global Industries, an offshore oil and gas construction company, was
also a strong performer during the period, benefiting from trends similar to
those that helped Parker Drilling.

Trammel Crow, a real estate management company, was also a strong performer for
the 12-month reporting period. The company benefited from a recovery in the
nonresidential real estate market, which had been weak despite the strength in
residential home building. THQ, a developer of interactive entertainment
software, performed well because of improved earnings from the company's
proprietary software releases. Priority Healthcare, a specialty pharmaceutical
distributor, also contributed positively to performance during the reporting
period, advancing on an acquisition bid from a rival company.

WHICH STOCKS UNDERPERFORMED?

As mentioned, Graftech International, a manufacturer of graphite electrodes sold
to the steel industry, was a significant detractor during the 12-month reporting
period. The company's share price plunged on dis-appointing volume and earnings
guidance for 2005. Because we believe the company's long-term fundamentals
remain positive, we used the sell-off as an opportunity to add to the Fund's
position.

Cost Plus, a specialty retailer of casual home furnishings and entertaining
products, declined during the 12-month reporting period, but we initiated the
Fund's position in May 2005 to take advantage of weak sales trends and a
management transition. We believe that the company may benefit from several
potentially positive catalysts, including a new management, easier same-store
sales comparisons, and high unit-volume growth.


Stocks of small companies may be subject to higher price volatility,
significantly lower trading volumes, and greater spreads between bid and ask
prices than stocks of larger companies. Small companies may be more vulnerable
to adverse business or market devel- opments than mid- or large-capitalization
companies.

 8   MainStay Small Cap Value Fund


Hooper Holmes, which provides risk assessment services primarily to the life
insurance industry, was down during the reporting period. The company suffered
from weakness in the life insurance market and from the board's decision to
replace both the CEO and CFO after several years of poor results.

Jo-Ann Stores, a fabric and craft materials retailer, fell during the reporting
period, on weaker-than-expected same-store sales and general concerns about
consumer spending. We took advantage of the weakness to add to the Fund's
position because we believe the stock represents a good long-term investment.
Hancock Fabrics, a fabric retailer, also declined during the reporting period,
although the Fund sold its position in June 2005.

WERE THERE ANY SIGNIFICANT EQUITY PURCHASES DURING THE REPORTING PERIOD?

In addition to Graftech International, Cost Plus, and Jo-Ann Stores, which we
previously discussed, the Fund initiated a position in Zoran in March 2005. The
company sells semiconductor chips for DVDs, digital phones, high-definition
digital televisions, and other growing end markets. We believe Zoran is
successfully diversifying its revenue stream away from just DVDs, a move that
could fuel significant earnings growth over the next several years.

Carmike Cinemas, which owns and operates theaters in small- and mid-sized
markets, was a new holding added to the Fund in July 2005. While the stock was
weak from our purchase through the end of the reporting period because of
lower-than-expected earnings and a weak box office, we believe that management
is focused on cutting costs and increasing cash flows.

In December 2004, we initiated a position in Kadant, a company that manufactures
and markets equipment and accessories for paper production. We believe that the
company's earnings may improve as a result a recent divestiture, efforts to
restructure the company's European manufacturing plant, and improving end-market
demand.

WHAT SECURITIES DID YOU SELL DURING THE REPORTING PERIOD?

During the reporting period, we eliminated several stocks, including Wabtec,
Post Properties, Pharmaceutical Product Development, and Steiner Leisure. Each
of these holdings reached the predetermined price targets we had set for the
stock.

Wabtec benefited from internal cost cutting and a recovery in demand and was
eliminated in October 2005. Multifamily apartment company Post Properties was
sold in June 2005, while recovering demand and a restructured property portfolio
helped push the company's stock price higher. Pharmaceutical Product
Development, a drug-discovery and services company, was eliminated from the Fund
in March 2005. The company had posted several quarters of better-than-expected
earnings growth, and the stock's valuation had become very expensive relative to
other investment opportunities. In June 2005, we sold the Fund's holdings in
Steiner Leisure, a company that manages spas for cruise ships and resorts.
Steiner Leisure had successfully increased earnings and market share and had
used free cash flow to improve the company's balance sheet and initiate a share
buyback program.

DID THE FUND'S WEIGHTINGS CHANGE DURING THE REPORTING PERIOD?

The Fund's sector weightings result primarily from our bottom-up security
selection process, which focuses on attractive valuations. Industry and security
movements may also affect weightings. During the 12-month period, the Fund's
exposure to the health care sector declined. This drop reflected profit-taking
in certain stocks, as well as takeovers in Priority Healthcare and Renal Care
Group. The Fund's health care holdings made a positive contribution to the
Fund's returns during reporting period.

The Fund's weighting in the consumer discretionary sector rose substantially.
The increase reflected the sector's underperformance and our subsequent ability
to find long-term investment opportunities within the sector. Adding to the
consumer discretionary weighting hurt the Fund's relative return during the
reporting period. As long-term investors, however, we believe the sector may
offer significant opportunities over the long term.

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 Small Cap
Value Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Distribution of Class A shares
and Class B shares commenced on June 1, 1998. Class C shares were initially
offered on September 1, 1998. Distribution of Class I shares commenced on
February 16, 2005. Class A shares are offered at net asset value per share plus
an initial sales charge. No sales charge applies on investments of $1 million or
more (and certain other qualified purchases) in Class A shares, but a contingent
deferred sales charge is imposed on certain redemptions of such shares within
one year of the date of purchase. Class B shares and Class C shares are offered
without an initial sales charge, although a declining contingent deferred sales
charge may be imposed on redemptions made within six years of purchase of Class
B shares and within one year of purchase of Class C shares. Class I shares are
not subject to sales charge. Distribution of Class I shares commenced on January
1, 2004. Class A, Class B, Class C and Class I shares bear the same voting
(except for issues that relate solely to one class), dividend, liquidation and
other rights and conditions. Each class of shares other than Class I shares
bears distribution and/or service fee payments under a distribution plan
pursuant to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a
distribution or service fee.

The Fund's investment objective is to seek long-term capital appreciation by
investing primarily in securities of small-cap companies.

Small-capitalization companies may be more volatile in price and have
significantly lower trading volumes than companies with larger capitalizations.
They may be more vulnerable to adverse business or market developments than
large-capitalization companies.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on the valuation date; such securities not
traded on the valuation date are valued at the mean of the latest quoted bid and
asked prices. Prices are normally taken from the principal market in which each
security trades. Temporary cash investments acquired over 60 days to maturity
are valued using the latest bid prices or using valuations based on a matrix
system (which considers such factors as security prices, yields, maturities, and
ratings), both as furnished by independent pricing services. Other temporary
cash investments are valued at amortized cost, which approximates market value.
Securities for which market quotations are not readily available are valued by
methods deemed in good faith by Board of Trustees to represent fair value.
Reasons for which securities may be valued in this manner include, but are not
limited to, trading for a security has been halted or suspended, a security has
been de-listed from a national exchange, or trading on a security's principal
market is temporarily closed at a time when under normal conditions it would be
open. The Fund did not hold securities at October 31, 2005, that were valued in
such manner.

(B) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See Note 7).

(C) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are withheld at the source.

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
quarterly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis

treatment; temporary differences do not require reclassification.

The following table discloses the current year reclassifications between
accumulated net investment loss, accumulated net realized gain on investments,
and additional paid-in-capital arising from permanent differences; net assets at
October 31, 2005, are not affected.

<Table>

     $1,036,304              $(925,790)           $(110,514)
- --------------------------------------------------------------
</Table>

The reclassification for the Fund is primarily attributable net operating losses
that offset undistributed net short-term securities gains for federal income tax
purposes, real estate investment trusts and distributions paid in connection
with the redemption of Fund shares.

(E) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on short-term securities are accreted and amortized,
respectively, on the straight line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(G) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(H) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.85% on assets up to $1.0 billion and
0.80% on assets in excess of $1.0 billion. Effective August 1, 2005, the Manager
has entered into a written expense limitation agreement, under which the Manager
has agreed to reimburse the expenses of the Fund so that the total operating
expenses (excluding taxes, interest, litigation, extraordinary expenses, and
brokerage and other transaction expenses relating to the purchase or sale of
portfolio investments) do not exceed, on an annualized basis, 1.90% of the
average daily net assets of the Class A shares. An equivalent reimbursement, in
an equal amount of basis points, will be applied to the other share classes. The
Manager, within three years of incurring such expenses, may recoup the amount of
any management fee waiver or expense reimbursement from the Fund pursuant to
this agreement if such recoupment does not cause the Fund to exceed the expense
limitations. This expense limitation may be modified or terminated only with the
approval of the Board of Trustees. Prior to August 1, 2005 and after July 1,
2004, NYLIM voluntarily agreed to waive a portion of its management fee in
excess of 0.60% of the Fund's average daily net assets. The Manager also agreed
to voluntarily reimburse the expenses of the Fund so that the total operating
expenses would not exceed on an annualized basis 1.90 of the average daily net
assets of the Class A shares, and such that there would be an equivalent
reduction for the other classes of shares. For the year ended October 31, 2005,
the manager earned

fees from the Fund in the amount of $1,287,432 and waived its fees and/or
reimbursed expenses in the amount of $378,656.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager pays the Subadvisor a monthly fee of one-half of the
management fee, net of management fee waivers, expense limitations and
reimbursements.. To the extent the manager has agreed to reimburse expenses of
the Fund, the Subadvisor has voluntarily agreed to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from
the Fund at an annual rate of 0.25% of the average daily net assets of the
Fund's Class A shares, which is an expense of the Class A shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The Plans provide that the Class B and Class C shares of the Fund also
incur a service fee at the annual rate of 0.25% of the average daily net asset
value of the Class B or Class C shares of the Fund. Class I shares are not
subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $34,828 for the year ended
October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $918, $62,234 and $2,222, respectively, for the year ended October 31,
2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund, for the year ended
October 31, 2005, amounted to $633,692.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus the Fund only pays a
portion of the fees identified above.

(F) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$4,094 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $41,813 for the year ended
October 31, 2005.

NOTE 10 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those arrangements and certain other levels of trading
by fund shareholders over the period from 1999 to 2003 may have had on the
funds. As a result of this review in December 2005, NYLIM made payments totaling
$5.9 million to nine MainStay funds. No payment was made with respect to the
MainStay Small Cap Value Fund. NYLIM has also agreed to reimburse or pay all
expenses relating to the Board of Trustees' review of this matter and has paid
substantially all of the costs associated with the other regulatory matters
described in this note.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Small Cap Value ("the Fund"), one
of the funds constituting The MainStay Funds, as of October 31, 2005, and the
related statement of operations for the year then ended, and the statements of
changes in net assets and financial highlights for each of the years in the
two-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Small Cap Value Fund of The MainStay Funds as of October 31, 2005, the
results of its operations for the year then ended, and the changes in its net
assets and financial highlights for each of the years in the two-year period
then ended, in conformity with U.S. generally accepted accounting principles.

 26   MainStay Small Cap Value Fund


BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreement, the Board of Trustees requested and received from the
Manager and Subadvisor, and reviewed, a wide variety of information. The
Trustees also requested and received information from outside data providers and
information and analysis from a third party consultant. The Trustees considered
various industry and regulatory trends in their deliberations. In considering
approval of these Agreements, and in evaluating the fairness of the compensation
to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and Subadvisor have provided historically to the Fund, and also
generally to other series of the Trust. The Manager's services to the Trust have
included investment management services, including the selection and supervision
of portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the
day-to-day management of the portfolio, providing reports to the Manager, and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. In considering the Manager's
and Subadvisor's practices relating to best execution of portfolio trades, the
Board reviewed reports of the Fund's Brokerage Committee including with respect
to analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager, the Subadvisor and certain other service
providers, as well as the Subadvisor's attention to its compliance program. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager and Subadvisor were such that, in the context of the Board's overall
review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared to multiple comparison groups, including with reference to
information provided by outside data providers and analyzed with the assistance
of a third party consultant. The Trustees referred to discussions held during
periodic meetings of the Performance Committee of the Board to discuss
investment performance-related matters with the Manager. In reviewing the Fund's
performance, the Board recognized the underperformance of the Fund over various
time periods relative to funds concluded by Trustees to be peers of the Fund but
acknowledged its recent approval of the selection of the Subadvisor as a new
subadviser for the Fund. The Trustees noted that, as the Subadvisor had not yet
provided subadvisory services to the Fund for a meaningful period of time, they
would monitor and evaluate such services over time.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees noted the Manager's
agreement to limit the Fund's net expenses to a certain level with respect to
the Fund with the expectation that the Manager intended, over time, to implement
measures designed to reduce the Trust's transfer agency fees. The Trustees
considered certain benefits expected for, and risks borne by, the Manager and
its affiliates, including benefits from soft dollar arrangements. The Trustees
considered the services provided to the Fund by affiliates of the Manager,
NYLIFE Distributors and NYLIM Service, under other agreements, and the benefits
to the Manager and its affiliates from those relationships. The information
provided to the Trustees indicated that the profitability to the Manager and its
affiliates arising directly from those other agreements was not excessive. The
Trustees acknowledged certain benefits to the reputation of the Manager and its
affiliates, as well to that of the Trust, from their association with each
other.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund grows, or as the Trust grows overall,
noting in

                                                    www.MAINSTAYfunds.com     27


particular the Manager's plans for marketing and distributing shares of various
series of the Trust. They noted the Manager's willingness to implement
contractual breakpoints, and that the contractual breakpoints in place for the
management fee were intended to provide that the Fund's shareholders would share
in benefits from economies of scale arising from the growth of Fund assets. The
Trustees acknowledged that the Fund had not yet reached the asset level at which
breakpoints would reduce the contractual management fee to which the Fund is
subject. Acknowledging the difficulty of forecasting economies of scale, the
Trustees generally expressed an intention to monitor the Manager's profitability
and consider the application of fee breakpoints or other appropriate measures as
the Board may determine from time to time. The Trustees reviewed historical
information about changes in the Fund's expense and asset levels over time, as
well as information about certain Fund expenses that would remain fixed even as
Fund assets increase and, therefore, provide the Fund with benefits from
economies of scale as the Fund grows. The Trustees noted that, to the extent the
Fund's gross expenses currently are higher than its net expenses, economies of
scale achieved through an increase in the Fund's assets might not directly
benefit the Fund through lower net expenses. The Trustees considered various
information about transfer agency expenses, including information showing that
transfer agency fees of the Fund and a significant number of series of the Trust
(although not every such series or with respect to every share class of each
series) tended to be high, when aggregated and expressed as a percentage of the
assets of certain series, compared to the mutual fund industry average according
to certain studies reviewed by the Board and, therefore, adversely affected
gross expense ratios. The Board received information about potential effects on
the Manager were it to subsidize certain portions of the Trust's transfer agency
fees. The Trustees noted that a significant number of shareholders of the
Trust's series had small amounts invested in the series, and have considered
measures intended to increase average shareholder account size and/or otherwise
reduce the Trust's transfer agency fees and expenses, including steps that the
Manager has taken to encourage shareholders to consolidate or close small
accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts, that had investment objectives similar to
that of the Fund. The Trustees took into account information provided by the
Manager or Subadvisor about the relative scope of services provided to the Fund
and to those accounts or explanations about the accounts' histories. In
considering the extent of the fees received by the Manager and Subadvisor for
providing services to the Fund, the Trustees evaluated factors such as the fees
and expenses borne by other registered funds in the market pursuing strategies
generally similar to those followed by the Fund. The Trustees considered the
Fund's historical and proposed contractual and net management fees, its
anticipated gross and net expense ratios, and various components of that expense
ratio, in comparison to other funds in comparison groupings prepared by outside
data providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.

At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.
The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.
Sincerely,


/s/ Christopher O. Blunt

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY EQUITY INDEX FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Francis J. Ok of New York Life
Investment Management LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its total assets in stocks contained
in the S&P 500(R) Index(1) in the same proportion, to the extent feasible, as
they are represented in the Index. In implementing this strategy, we use
statistical techniques to determine which stocks are to be purchased or sold to
replicate the S&P 500(R) Index to the extent feasible. The Fund's investments
also include S&P 500(R) Index futures, which are used for cash management
purposes.

WHAT WERE THE MAJOR FACTORS THAT AFFECTED THE STOCK MARKET DURING THE 12 MONTHS
ENDED OCTOBER 31, 2005?

For the 12 months ended October 31, 2005, all broadly watched equity indices
provided positive performance. Mid- and small-capitalization stocks generally
outperformed their large-cap counterparts. The market favored value stocks over
growth stocks at all capitalization levels. Despite wide fluctuations in
crude-oil prices, instability in many regions of the world, and the devastation
caused by hurricanes Katrina and Rita, the U.S. stock market posted significant
gains during the 12-month period ended October 31, 2005.

The Federal Open Market Committee continued to raise its target for the federal
funds rate, with eight 25-basis-point increases during the reporting period. (A
basis point is one-hundredth of a percentage point.) At the end of October 2005,
the federal funds target rate stood at 3.75%, its highest level in more than
four years. Among the considerations that influenced the gradual tightening
policy were mounting inflationary pressures, low unemployment, an upward path of
record energy prices, and growing labor costs.

WHAT WERE THE BEST-PERFORMING INDUSTRIES IN THE S&P 500(R) INDEX DURING THE
REPORTING PERIOD?

From a total-return perspective, tobacco was the best-performing industry for
the 12 months ended October 31, 2005. Other top-performing industries from a
total-return perspective included health care providers & services, energy
equipment & services, construction & engineering, and independent power
producers & energy traders.

On the basis of impact, which takes weightings and total returns both into
account, the industry that made the strongest contribution to the performance of
the Index was oil, gas & consumable fuels. The second-strongest contributor was
health care providers & services, followed by insurance, capital markets, and
tobacco.

WHICH INDUSTRIES WERE THE WORST PERFORMERS?

On the basis of total returns alone, the worst-performing industry in the Index
for the 12-month reporting period was automobiles. The second-worst total return
came from Internet & catalog retail, followed by leisure equipment & products,
auto components, and thrifts & mortgage finance.

For the 12 months ended October 31, 2005, media was the industry with the
greatest negative impact on Index performance when weightings and total returns
were both considered. Pharmaceuticals was next, followed by thrifts & mortgage
finance, automobiles, and Internet & catalog retail.

WHICH INDIVIDUAL STOCKS WERE THE BEST PERFORMERS DURING THE REPORTING PERIOD?

For the 12 months ended October 31, 2005, the S&P 500(R) Index stock with the
highest total return was Valero Energy. Express Scripts had the second-best
total return, followed by NVIDIA, Humana, and Apple Computer. Each of these top
performers more than doubled in price during the reporting period.

The five stocks with the greatest positive impact on the performance of the S&P
500(R) Index all had higher weightings and lower total returns. On the basis of
impact, which takes weightings and total returns both into account, the
strongest positive contributor to the performance of the Index for the 12-month
reporting period was Altria Group. The second-best contributor was ExxonMobil,
followed by ConocoPhillips, UnitedHealth Group, and Hewlett-Packard.

WHICH STOCKS WERE THE WEAKEST PERFORMERS DURING THE REPORTING PERIOD?

For the 12-months ended October 31, 2005, the S&P 500(R) Index stock with the
worst total return was Sanmina-SCI. Other particularly weak performers


This Fund was closed to new purchases as of January 1, 2002.
Index funds generally seek to reflect the performance of an index or an
allocation among indices, unlike other funds, whose objectives may, in some
cases, involve seeking to outperform an index or other benchmark. The Fund may
invest in derivatives, which may increase the volatility of the Fund's net asset
value and may result in a loss to the Fund.

included Unisys, Gateway, Lexmark International, and Dana.

On the basis of impact, which takes weightings and total returns both into
account, Pfizer made the greatest negative contribution to the performance of
the Index for the 12-month reporting period. Wal-Mart Stores was next, followed
by Fannie Mae, Verizon Communications, and International Business Machines.

WERE ANY CHANGES MADE TO THE FUND OR TO THE INDEX DURING THE PERIOD?

The Fund seeks to track the performance and weightings of stocks in the S&P
500(R) Index. The Index itself, however, may change from time to time as
companies merge, divest units, add to their market capitalization, or face
financial difficulties. Standard & Poor's may also occasionally adjust the Index
to better reflect the companies that it believes are most representative of the
makeup of the U.S. economy. During the 12 months ended October 31, 2005, there
were 20 additions to the Index and 20 deletions from it.

Among the additions were well-known companies such as Compass Bancshares,
Vornado Realty Trust, Tyson Foods, Public Storage, and Lennar. Among the
deletions were familiar names such as Deluxe, Winn-Dixie Stores, Delta Air
Lines, Unocal, and Delphi. When Sears, Roebuck merged with Kmart, the stock was
deleted from the Index but simultaneously reappeared as Sears Holdings. Adolf
Coors merged with Molson and was deleted when Molson Coors Brewing was added to
the Index. Peoplesoft was deleted from the Index because the company was
acquired by Oracle; Nextel Communications was deleted when the company was
acquired by Sprint; and Wellpoint Health Networks was deleted when it was
acquired by Anthem.

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 share purchases effective January 1, 2002. Existing
shareholders may continue to maintain share positions held in the Fund, elect or
continue to reinvest distributions, and NYLIFE LLC will continue to honor the
unconditional guarantee associated with the Fund (see Note 10).

The Fund's investment objective is to seek to provide investment results that
correspond to the total return performance (and reflect reinvestment of
dividends) of publicly traded common stocks represented by the Standard & Poor's
500 Composite Stock Price Index. The Fund is "non-diversified," which means that
it may invest a greater percentage of its assets than diversified funds in a
particular issuer. This may make it more susceptible than diversified funds to
risks associated with an individual issuer, and to single economic, political or
regulatory occurrences.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on the valuation date; such securities not
traded on the valuation date are valued at the mean of the latest quoted bid and
asked prices. Prices normally are taken from the principal market in which each
security trades. Temporary cash investments acquired over 60 days to maturity
are valued using the latest bid prices or using valuations based on a matrix
system (which considers such factors as security prices, yields, maturities, and
ratings), both as furnished by independent pricing services. Other temporary
cash investments are valued at amortized cost, which approximates market value.
Futures contracts are valued at the last posted settlement price on the market
where such futures are principally traded. Securities for which market
quotations are not readily available are valued by methods deemed in good faith
by Board of Trustees to represent fair value. Reasons for which securities may
be valued in this manner include, but are not limited to, trading for a security
has been halted or suspended, a security has been de-listed from a national
exchange, or trading on a security's principal market is temporarily closed at a
time when under normal conditions it would be open. The Fund did not hold
securities at October 31, 2005, that were valued in such manner.

(B) FUTURES CONTRACTS.  A futures contract is an agreement to purchase or sell a
specified quantity of an underlying instrument at a specified future date and
price, or to make or receive a cash payment based on the value of a securities
index. During the period the futures contract is open, changes in the value of
the contract are recognized as unrealized gains or losses by "marking to market"
such contract on a daily basis to reflect the market value of the contract at
the end of each day's trading. The Fund agrees to receive from or pay to the
broker an amount of cash equal to the daily fluctuation in the value of the
contract. Such receipts or payments are known as "variation margin". When the
futures contract is closed, the Fund records a realized gain or loss equal to
the difference between the proceeds from (or cost of) the closing transaction
and the Fund's basis in the contract. The Fund invests in stock index futures
contracts to gain full exposure to changes in stock market prices to fulfill its
investment objective.

The use of futures contracts involves, to varying degrees, elements of market
risk in excess of the amount recognized in the Statement of Assets and
Liabilities. The contract or notional amounts and variation margin reflect the
extent of the Fund's involvement in open futures positions. Risks arise from the
possible imperfect correlation in movements in the price of futures contracts,
interest rates and the underlying hedged assets, and the possible inability of
counterparties to meet the terms of their contracts. However, the Fund's
activities in futures contracts are conducted through regulated exchanges which
minimize counterparty credit risks.

(C) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund.

(D) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of

 22   MainStay Equity Index Fund


the Fund within the allowable time limits. Therefore, no federal income or
excise tax provision is required.

(E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
and capital gain distributions, if any, annually. Income dividends and capital
gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

The following table discloses the current period reclassification between
accumulated undistributed net investment income, accumulated net realized loss
on investments and additional paid-in-capital arising from permanent
differences; net assets at October 31, 2005, are not affected.

<Table>
<Caption>
                        ACCUMULATED
     UNDISTRIBUTED     NET REALIZED
    NET INVESTMENT          LOSS ON        ADDITIONAL
            INCOME      INVESTMENTS   PAID-IN-CAPITAL
                                
    $      (12,906)  $       12,907   $            (1)
</Table>

The reclassification for the Fund is due to real estate investment trust
distributions.

The Fund declared a dividend of $0.4138 per share which was paid on December 21,
2004, and also underwent a reverse share split on that day. The reverse share
split rate was 0.9897 per share outstanding calculated on fund shares
outstanding immediately after reinvestment of dividends.

Certain amounts in the Financial Highlights and Notes to Financial Statements
(see Note 9) have been adjusted to reflect the cumulative effects of this
reverse stock split, those that occurred in each of the periods presented, and
the reverse stock split that occurred in December 2005. (See Note 12)

(F) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on short-term securities are accreted and amortized,
respectively, on the straight line method.

(G) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(H) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(I) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER.  New York Life Investment Management LLC ("NYLIM" or the
"Manager"), an indirect wholly-owned subsidiary of New York Life, serves as the
Fund's Manager. The Manager provides offices, conducts clerical, recordkeeping
and bookkeeping services, and keeps the financial and accounting records
required for the Fund. The Manager also pays the salaries and expenses of all
personnel affiliated with the Fund and all the operational expenses that are not
the responsibility of the Fund. The Fund is advised by the Manager directly,
without a Subadvisor.

The Trust, on behalf of the Fund, paid the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets. Effective as of August 1, 2004, NYLIM had voluntarily
agreed to waive its management fee by 0.25% to 0.25% of the Fund's average net
assets. Effective August 1, 2005, the contractual management fee for the Fund
was reduced to 0.25% of assets up to $1.0 billion; 0.225% from $1.0 billion to
$3.0 billion; and 0.20% in excess of $3.0 billion. In addition, effective August
1, 2005, the Manager has entered into a written expense limitation agreement,
under which the Manager has agreed to reimburse the expenses of the Fund so that
the total operating expenses (excluding taxes, interest, litigation,
extraordinary expenses, and brokerage and other transaction expenses relating to
the purchase or sale of portfolio investments) do not exceed, on an annualized
basis, 0.65% of the average daily net assets of the Fund. The Manager,

                                                    www.MAINSTAYfunds.com     23

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

within three years of incurring such expenses, may recoup the amount of any
management fee waiver or expense reimbursement from the Fund pursuant to this
agreement if such recoupment does not cause the Fund to exceed the expense
limitations. At October 31, 2005, the Fund had $209,184 of recoupment available.
This amount is available until October 31, 2008. This expense limitation may be
modified or terminated only with the approval of the Board of Trustees. Prior to
August 1, 2005, NYLIM agreed to voluntarily reimburse the expenses of the Fund
so that the total operating expenses would not exceed on an annualized basis
0.80% of the average daily net assets of the Fund. For the year ended October
31, 2005, the Manager earned fees from the Fund in the amount of $2,974,068 and
waived and/or reimbursed expenses in the amount of $1,696,218.

(B) DISTRIBUTION FEES.  The Trust, on behalf of the Fund, has a Distribution
Agreement with NYLIFE Distributors LLC (the "Distributor"), an indirect
wholly-owned subsidiary of New York Life. The Fund has adopted a distribution
plan (the "Plan") in accordance with the provisions of Rule 12b-1 under the 1940
Act.

Pursuant to the Plan, the Distributor receives payments from the Fund at an
annual rate of 0.25% of the Fund's average daily net assets, which is an expense
of the Fund for distribution or service activities as designated by the
Distributor.

The Plan provides that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund for the year ended
October 31, 2005, amounted to $1,045,865.

(D) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus the Fund only pays a
portion of the fees identified above.

(E) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$15,300 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $86,148 for the year ended
October 31, 2005.

NOTE 4 -- CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, The Bank of New York acted as custodian for the Fund.

NOTE 5 -- FEDERAL INCOME TAX:

At November 30, 2004, the Fund's year end for federal income tax purposes, the
components of accumulated gain/(loss) on a tax basis were as follows:

<Table>
<Caption>
UNDISTRIBUTED     ACCUMULATED                        TOTAL
     ORDINARY         CAPITAL     UNREALIZED   ACCUMULATED

$   6,496,775   $(122,345,938)  $159,582,678   $43,733,515
</Table>

The difference between book-basis and tax-basis unrealized depreciation is due
to wash sale deferrals, and mark-to-market of futures contracts.

At November 30, 2004, for federal income tax purposes, capital loss
carryforwards of $122,345,938 were available as shown in the table below, to the
extent provided by the regulations to offset future realized gains of the Fund
through the years indicated. To the extent that these loss carryforwards are
used to offset future capital gains, it is

 24   MainStay Equity Index Fund


probable that the capital gains so offset will not be distributed to
shareholders.

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

credit during the year ended October 31, 2005.

NOTE 10 -- GUARANTEE:

NYLIFE LLC ("NYLIFE"), a wholly-owned subsidiary of New York Life, will
guarantee unconditionally and irrevocably pursuant to a Guaranty Agreement
between NYLIFE and the Fund (the "Guarantee") that if, on the business day
immediately after ten years from the date of purchase (the "Guarantee Date"),
the net asset value ("NAV") of a Fund share plus the value of all dividends and
distributions paid, including cumulative reinvested dividends and distributions
attributable to such share paid during that ten-year period ("Guaranteed
Share"), is less than the price initially paid for the Fund share ("Guaranteed
Amount"), NYLIFE will pay shareholders an amount equal to the difference between
the Guaranteed Amount for each such Guaranteed Share outstanding and held by
shareholders as of share and the net asset value of each such of the close of
business on the Guarantee Date. For the services that NYLIM and its affiliates
provide to the Fund, they receive the fees described in the prospectus. Neither
NYLIM nor its affiliates receive a separate fee for providing the Guarantee,
although the Guarantee has been considered in connection with the annual renewal
of the management fee. (see Note 3.)

NOTE 11 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by

                                                    www.MAINSTAYfunds.com     25

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those arrangements and certain other levels of trading
by fund shareholders over the period from 1999 to 2003 may have had on the
funds. As a result of this review in December 2005, NYLIM made payments totaling
$5.9 million to nine MainStay funds. The amount paid to the MainStay Equity
Index Fund was $516,000. NYLIM has also agreed to reimburse or pay all expenses
relating to the Board of Trustees' review of this matter and has paid
substantially all of the costs associated with the other regulatory matters
described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the Fund and the fees and expenses of the fund as
well as the related guarantee disclosure to Fund shareholders. Discussions have
been held with the SEC concerning a possible resolution of this matter. There
can be no assurance of the outcome of these efforts.

NOTE 12 -- SUBSEQUENT EVENT:

Subsequent to October 31, 2005, the Fund declared a dividend of 0.5112 per share
which was paid on December 21, 2005, and also underwent a reverse share split on
that day. The reverse share split rate was 0.9880 per share outstanding
calculated on fund shares outstanding immediately after reinvestment of
dividends.

Certain amounts in the Statement of Assets and Liabilities, Financial
Highlights, and Notes to Financial Statements (see Note 9) have been adjusted to
reflect the effects of this subsequent reverse stock split.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Equity Index Fund ("the Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2005, and
the related statement of operations for the year then ended, and the statements
of changes in net assets and financial highlights for each of the years in the
two-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Equity Index Fund of The MainStay Funds as of October 31, 2005, the
results of its operations for the year then ended, and the changes in its net
assets and financial highlights for each of the years in the two-year period
then ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement, the Board of
Trustees requested and received from the Manager, and reviewed, a wide variety
of information. The Trustees also requested and received information from
outside data providers and information and analysis from a third party
consultant. The Trustees considered various industry and regulatory trends in
their deliberations. In considering approval of the Agreement, and in evaluating
the fairness of the compensation to be paid by the Fund, the Trustees met a
number of times as a full Board and in executive sessions of only the Non-
Interested Trustees to discuss the Board's consideration of the approval of the
Agreement, and took into account a number of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager. The Trustees reviewed the services that the Manager has
provided historically to the Fund, and also generally to other series of the
Trust. The Manager's services to the Trust have included investment management
services, including the day-to-day management of the portfolio and the selection
and supervision of portfolio managers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, managing reverse stock splits, performing
clerical and bookkeeping services for the Fund, preparing Fund filings, and
other administrative services. The Trustees considered, among other things, the
Manager's management, personnel, resources, operations and portfolio management
capabilities. In considering the Manager's practices relating to best execution
of portfolio trades, the Board reviewed reports of the Fund's Brokerage
Committee including with respect to analysis prepared by Plexus Group. The
Trustees considered the Manager's supervision of the Fund's service providers
and its attention to the compliance program of the Trust, the Manager and
certain other service providers. The Trustees noted the generally favorable
conclusions of financial services research firm DALBAR Inc. of the services,
investor complaint levels, and communications that NYLIM Service Company LLC
("NYLIM Service"), an affiliate of the Manager, has provided to Trust
shareholders. The Trustees acknowledged the guarantee feature and the role of an
affiliate of the Manager with regard to the guarantee. A majority of the
Trustees, including a majority of the Non-Interested Trustees, concluded that,
overall, the nature, extent and quality of the services expected to be provided
by the Manager were such that, in the context of the Board's overall review of
various factors, the Management Agreement should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's success in providing investment
results that corresponded to the total return performance of stocks representing
the S&P 500 Index.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees noted the Manager's
agreement to reduce the Fund's management fee and limit the Fund's net expenses
to a certain level with respect to the Fund. The Trustees considered certain
benefits expected for, and risks borne by, the Manager and its affiliates,
including benefits from soft dollar arrangements. The Trustees considered the
services provided to the Fund by affiliates of the Manager, NYLIFE Distributors
and NYLIM Service, under other agreements, and the benefits to the Manager and
its affiliates from those relationships. The information provided to the
Trustees indicated that the profitability to the Manager and its affiliates
arising directly from those other agreements was not excessive. The Trustees
acknowledged certain benefits to the reputation of the Manager and its
affiliates, as well to that of the Trust, from their association with each
other.

The Trustees, in considering economies of scale, noted that the Fund is closed
to new share purchases and, for that reason, can increase its asset size only
through capital appreciation. The Trustees discussed the extent to which
economies of scale were projected by the Manager to be realized as the Trust
grows overall, noting in particular the Manager's plans for marketing and
distributing shares of various series of the Trust. Acknowledging the difficulty
of forecasting economies of scale, the Trustees generally expressed an intention
to monitor the Manager's profitability and consider the application of fee
breakpoints or other appropriate measures as the Board may determine from

                                                    www.MAINSTAYfunds.com     31


time to time. They noted the implementation of a contractual management fee
breakpoint that would reduce the contractual management fee to which the Fund is
subject were the Fund to reach the applicable asset level. The Trustees noted
that, to the extent the Fund's gross expenses currently are higher than its net
expenses, economies of scale achieved through an increase in the Fund's assets
might not directly benefit the Fund through lower net expenses. The Trustees
considered various information about transfer agency expenses, including
information showing that transfer agency fees of a significant number of series
of the Trust (although not every such series or with respect to every share
class of each series) tended to be high, when aggregated and expressed as a
percentage of the assets of certain series, compared to the mutual fund industry
average according to certain studies reviewed by the Board and, therefore,
adversely affected gross expense ratios. The Board received information about
potential effects on the Manager were it to subsidize certain portions of the
Trust's transfer agency fees.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager, including other registered funds and separate
institutional accounts, that had investment objectives similar to that of the
Fund. The Trustees took into account information provided by the Manager about
the relative scope of services provided to the Fund and to those accounts or
explanations about the accounts' histories. In considering the extent of the
fees received by the Manager for providing services to the Fund, the Trustees
evaluated factors such as the fees and expenses borne by other registered funds
in the market pursuing strategies generally similar to those followed by the
Fund. The Trustees considered the Fund's historical and proposed contractual and
net management fees, its anticipated gross and net expense ratios, and various
components of that expense ratio, in comparison to other funds in comparison
groupings prepared by outside data providers using objective methodologies.

The Trustees acknowledged the historical relationship between the Manager and
the Trust and the likely difficulties in implementing an alternative to the
investment management arrangement between them. The Trustees also took account
of the results of their various discussions with the Manager concerning the
levels of the Fund's contractual and net management fees and the Fund's
anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreement. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreement.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreement, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of this Agreement was in the best
interests of the Fund and its shareholders.

                    Annual Report
                    October 31, 2005


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.

At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

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,

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY MAP FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Michael J. Mullarkey, Roger Lob, and
Christopher Mullarkey of Markston International LLC and by portfolio managers
Mark G. DeFranco and Brian M. Gillott of Jennison Associates LLC

CAN YOU DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 65% of its total assets in equity-type
securities, including common stocks, as well as securities convertible into, or
exchangeable for, common stocks. The Fund employs two subadvisors, Markston
International and Jennison Associates, with complementary investment processes
and styles. In pursuing the Fund's investment objective, each subadvisor seeks
to identify securities that are out of favor but have a catalyst that the
subadvisor believes will lead to improved performance.

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED
OCTOBER 31, 2005?

Markston International:
There were several economic crosscurrents during the 12 months ending October
31, 2005. Higher energy prices were among the most notable. Markston's share of
the Fund was overweighted in energy.

Jennison Associates:
Mixed economic data left the equity markets unsettled during the reporting
period. Equities started with strength, but began to retrace their gains as oil
prices climbed to record highs. Elevated energy prices, higher inflation, and
rising interest rates were among investors' chief concerns. Even so, equity
indices moved higher across the board during the 12 months ended October 31,
2005. From a sector perspective, utilities and energy led the S&P 500(R)
Index,(1) while more economically sensitive sectors trailed.

WHAT FACTORS MOST SIGNIFICANTLY AFFECTED FUND PERFORMANCE DURING THE REPORTING
PERIOD?

Markston International:
We believe that our time and labor intensive approach, which attempts to find
what we term "alpha generators"(2) in the securities we consider for investment,
helped the portion of the Fund we manage to more than double the performance of
the S&P 500(R) Index for the reporting period. We typically look for the
presence of three of the following six "alpha generators": insider buying, stock
repurchase by the company, meaningful restructuring, new management, companies
that operate in consolidating industries, and the presence of tax loss
carryforwards.

Jennison Associates:
Our portion of the Fund's portfolio outperformed the S&P 500(R) Index during the
reporting period. Energy sector holdings made the greatest positive contribution
to performance in our portion of the Fund's portfolio. Our weighting and
stock-selection decisions helped energy holdings in our portion of the Fund
outpace related stocks in the S&P 500(R) Index. With growth in global demand,
difficulties in reserve-replacement, and setbacks in production growth, oil
services companies were able to raise prices as equipment and crews approached
full utilization. Integrated oil companies and larger exploration & production
companies actually became less price-sensitive and more willing to pay high
prices to secure crews and equipment for longer periods.

Effective stock selection in the financials, information technology, and health
care sectors also bolstered both absolute and relative results in our portion of
the Fund's portfolio. Significant exposure to the materials sector added to
absolute returns, but individual stock disappointments led our materials
holdings to lag the broad equity market. Modest exposure to utilities detracted
from relative performance as well. Only the telecommunications services sector
hurt our portion of the Fund's performance on both an absolute and relative
basis.

WHAT WERE SOME OF THE FUND'S STRONG PERFORMERS DURING THE REPORTING PERIOD?

Markston International:
Our portion of the Fund benefited from its position in Genentech, a leading
biotechnology firm. Genen-tech's stock appreciated substantially after the
company reported that its primary cancer drug, Avastin, was effective in
fighting small-cell lung cancer. Genentech developed Avastin without a partner,
so it has maintained the bulk of the profits from the drug.


Mid-capitalization companies are generally less established and their stocks may
be more volatile and less liquid than the securities of larger companies. Stocks
of small companies may be subject to higher price volatility, significantly
lower trading volumes, and greater spreads between bid and ask prices than
stocks of larger companies. Small companies may be more vulnerable to adverse
business or market developments than mid- or large-capitalization companies.
Funds that invest in bonds are subject to credit, inflation, and interest-rate
risk and can lose principal value when interest rates rise. Issuers of
convertible securities may not be as financially strong as those issuing
securities with higher credit ratings and may be more vulnerable to changes in
the economy. If an issuer stops making interest payments, principal payments, or
both on its convertible securities, these securities may become worthless and
the Fund could lose its entire investment in them.

2. Alpha is a measure of excess return adjusted for volatility.

                                                     www.MAINSTAYfunds.com     7


Devon Energy appreciated during the reporting period as the price of oil
increased. Devon Energy is a frugally run oil and gas independent that has
consistently increased reserves per share, has insider buying by management, a
substantial stock-repurchase program, and a policy of restructuring periodically
to upgrade the company's properties. Part of our position came from other stocks
we owned that were acquired by Devon Energy.

Another strong performer for our portion of the Fund was Cerner, a software and
systems provider to the hospital industry. The company initially attracted us
because of insider buying, management changes, and restructuring activity.
Cerner has shown strong execution, posting above-average growth while
successfully furthering its penetration into the U.K. and French markets.

American Commercial Lines is one of the larger commercial barge operators in the
United States. The stock advanced dramatically when low-cost barge
transportation came into demand as oil prices rose and the number of coal
shipments by barge increased. During the reporting period, American Commercial
Lines emerged from a substantial reorganization under the leadership of new
management.

Chesapeake Energy, the second-largest independent producer of natural gas in the
United States, saw its stock appreciate during the reporting period because of
the enormous rise in natural gas prices. Since Chesapeake Energy has no assets
in the Gulf of Mexico, the company was not affected by hurricanes Katrina and
Rita.

Jennison Associates:
Our holdings in oil services companies performed particularly well, including
Todco, National Oilwell Varco, and BJ Services. These stocks benefited from
oil-related trends that we've previously discussed.

Pharmacy benefits manager Medco Health Solutions was also among the strongest
contributors to performance in our portion of the Fund's portfolio. The company
performed well on better-than-expected new-business sign-ups and positive
prospects for administering Medicare drug programs in 2006. We reduced our
position in the stock, however, when it approached our target valuation.

Health management organization Cigna's shares rose when investors gained
confidence in the company's ongoing restructuring efforts. We sold our position
in Cigna toward the end of the reporting period, taking profits. UnumProvident,
a leading provider of disability and specialty risk insurance, also strengthened
results in our portion of the Fund's portfolio. The company continued to execute
its disability-business turnaround successfully by focusing on the strong middle
market and completing the repricing of UnumProvident's unprofitable
national-account business. We trimmed the Fund's position in the stock, even
though we continued to feel that it was attractively valued.

WHAT STOCKS UNDERPERFORMED DURING THE REPORTING PERIOD?

Markston International:
The Fund's position in Eyetech Pharmaceuticals, an emerging biotech company that
pursues unmet eye-related medical needs, detracted from results. Eyetech
developed an FDA-approved drug, Macugen, to treat wet macular degeneration. The
company's stock declined after interim data from Genentech suggested that a
competing Genentech compound, if approved, could give Macugen serious
competition. Eyetech was recently acquired by OSI Pharmaceuticals.

Another poor performer for our portion of the Fund was Gemstar-TV Guide
International. The company completed several deals that gave customers access to
the company's intellectual property in return for cash and various industrial
arrangements. Unfortunately, the company has faced more challenges than it has
managed to meet. We reduced the Fund's stake in the holding.

S1, a small software supplier to companies offering financial services, saw its
shares decline when the company had trouble meeting its growth projections.
During the reporting period, S1's Board of Directors changed CEOs, a
nonstrategic asset was sold, and the company materially cut costs. At current
prices, we think S1 represents value.

Symbol Technologies, a major participant in the bar code and emerging
radio-frequency ID industry, detracted from results. The company has put
allegations of a previous management team's misconduct to rest. Current
management has cut costs to improve profitability, and we think the company is
on the mend.

Our position in Boston Scientific, a medical-device company, underperformed when
competitor Johnson & Johnson gained market share in the drug-eluting coronary
stent market. Boston Scientific appears to have stabilized at a price/earnings
multiple that is at a discount to most other medical-device suppliers.

Jennison Associates:
Generic drug manufacturer Andrx detracted from results in our portion of the
Fund's portfolio. The company was set back when the Food and Drug Administration
placed the company on "official action indicated" status, which effectively put
all of

 8   MainStay MAP Fund


the com-pany's new drug applications on hold. Andrx also lost its chief
financial officer and general counsel. We trimmed the Fund's position in Andrx,
and have continued to monitor the company's situation closely.

GrafTech International, which makes graphite and carbon products used in steel
and aluminum production, lost volume when the company decided to raise prices to
reflect higher costs for raw materials. We eliminated the stock from our portion
of the Fund on concerns about steel prices and GrafTech's financial leverage.

We sold electronic-equipment company Symbol Technologies at a loss, when the
closely timed departures of the CEO and the CFO raised the company's risk
profile.

Shares of aluminum giant Alcoa slipped when the company announced layoffs, plant
closings, and consolidations scheduled during the next several months. Aluminum
stocks also came under pressure from concerns that Chinese production growth and
export potential might upset an otherwise healthy global supply-and-demand
balance.

Radio One, a media company, saw its share price decline when the company's
revenue trends came in, below the market's expectations. Investments in
improving content have also added to expenses, but we remain optimistic about
pricing potential later in the year.

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD?

Markston International:
We either established new positions or added to the Fund's existing positions in
several companies. American Express appears to be in a higher-growth mode.
Morgan Stanley has new management, which we believe will benefit the company.
Amgen appears to be on the verge of some new drug approvals. Union Pacific is
getting a new CEO, is enjoying improved pricing, and appears to have enhanced
productivity. Pogo Producing restructured to move its operations to North
America. W.R. Berkley's exploitation of market niches has helped it post a
return-on-equity ratio of more than 20%. Covanta Holding, formerly Danielson
Holding, has emerged as the market leader in waste-to-electricity generation.
The company has a large tax loss carryforward and generates substantial cash
flow. On balance, these holdings helped relative performance in our portion of
the Fund's portfolio during the reporting period.

Jennison Associates:
We continue to build our portion of the Fund's portfolio one stock at a time,
using a bottom-up, research-intensive process. During the reporting period, we
established and then added to a position in insurance company American
International Group because of the stock's attractive valuation. We also
initiated a position in Royal Bank of Scotland, a top-10 global bank with its
several well-known retail franchises, including Citizen's Bank and Charter One
Financial in the United States and Nat West and Royal Bank of Scotland in the
U.K. Greenwich Capital Markets gives Royal Bank of Scotland a strong
capital-markets franchise in the United States. We established a position in BJ
Services, a global oil service company that specializes in pressure pumping and
is particularly exposed to the North American natural gas market. We believe the
company should continue to benefit from the supply-and-demand imbalance in oil
and natural gas. We established a position in capital markets firm Charles
Schwab early in the Fund's fiscal year and have increased the position
throughout the reporting period. We also increased our position in Kroger, the
largest pure grocery chain in the United States.

WHAT SECURITIES DID YOUR PORTION OF THE FUND'S PORTFOLIO SELL DURING THE
REPORTING PERIOD?

Markston International:
We can and do sell stocks for a variety of reasons, including controlling
portfolio volatility. During the reporting period, we reduced our positions in
Tyco International and Cell Therapeutics, among others, at attractive prices.

Jennison Associates:
On the basis of our stringent risk/reward criteria, we eliminated our position
in Companhia Vale do Rio Doce, one of the world's largest iron-ore producers. We
also exited our position in Cigna. We eliminated our position in Great Lakes
Chemical when the company's share price rose on news of a friendly acquisition
by Crompton Corporation. In our portion of the Fund, we also sold positions in
Cooper Cameron, a leading subsea equipment manufacturer, and in National Oilwell
Varco, an oil rig equipment manufacturer. In each of these cases, we were able
to take profits for the Fund.

DID THE FUND CHANGE ITS INDUSTRY GROUP WEIGHTINGS?

Markston International:
Our portion of the Fund began the reporting period with overweighted positions
relative to the S&P 500(R) Index in energy, financials, industrials, materials,
and utilities and with underweighted positions in consumer discretionary,
consumer staples, information

                                                     www.MAINSTAYfunds.com     9


technology, and telecommunications services. We had a relatively equal weighting
to the Index in health care. During the reporting period, we slightly increased
the Fund's exposure to the financials sector and modestly decreased the Fund's
allocation to information technology.

Jennison Associates:
Any weighting changes in our portion of the Fund's portfolio are a consequence
of our bottom-up stock-selection process and do not reflect a "sector bet" on
the part of our management team. During the reporting period, the risk/reward
discipline that guides our portion of the Fund's portfolio led us to take
profits in many strong performers, increase our weightings in health care and
utilities, and decrease our weightings in basic materials and energy. We trimmed
the Fund's exposure to materials, because of inventory increases that resulted
from slower economic growth during the first half of 2005. In the energy sector,
we continued to hold oil services companies, where earnings continued to
accelerate, and we eliminated positions in the oil & gas exploration &
production and integrated oil & gas subindustries. We continued to limit
exposure to banks in our portion of the Fund's portfolio in an attempt to remain
insulated from the effects of a flattening yield curve.

HOW DO THE FUND'S WEIGHTINGS DIFFER FROM THOSE OF ITS BENCHMARK?

Markston International:
As of October 31, 2005, the portion of the Fund we manage was underweighted
relative to the S&P 500(R) Index in the consumer discretionary, consumer
staples, information technology, and telecommunications services sectors. At the
same time, the Fund held overweighted positions relative to the Index in the
utilities, materials, industrials, financials, and energy sectors and a
relatively neutral position in health care. Our portion of the Fund's portfolio
also held a sizable position in cash.

Jennison Associates:
As of October 31, 2005, our portion of the Fund's portfolio was overweighted
relative to the S&P 500(R) Index in the consumer discretionary and materials
sectors and underweighted relative to the Index in the consumer staples,
information technology, and industrials sectors.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 -- ORGANIZATION AND BUSINESS:

The MainStay Funds (the "Trust") was organized on January 9, 1986 as a
Massachusetts business trust. The Trust is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end management
investment company and comprises nineteen funds (collectively referred to as the
"Funds"). These financial statements and notes relate only to MainStay MAP Fund
(the "Fund"), a diversified fund.

The Fund currently offers six classes of shares. Class A shares, Class B shares,
Class C shares, Class I shares, Class R1 shares and Class R2 shares.
Distribution of Class A shares, Class B shares, Class C shares and Class I
shares commenced on June 9, 1999. Distribution of Class R1 shares and Class R2
shares commenced on January 2, 2004. Class A shares are offered at net asset
value per share plus an initial sales charge. No sales charge applies on
investments of $1 million or more (and certain other qualified purchases) in
Class A shares, but a contingent deferred sales charge is imposed on certain
redemptions of such shares within one year of the date of purchase. Class B
shares and Class C shares are offered without an initial sales charge, although
a declining contingent deferred sales charge may be imposed on redemptions made
within six years of purchase of Class B shares and within one year of purchase
of Class C shares. Class I, Class R1 and Class R2 shares are not subject to a
sales charge. The six classes of shares bear the same voting (except for issues
that relate solely to one class), dividend, liquidation, and other rights and
conditions except that Class B shares and Class C shares are subject to higher
distribution fee rates than Class A shares and Class R2 shares under a
distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares and
Class R1 shares are not subject to a distribution or service fee. Class R1 and
Class R2 shares are authorized to pay to New York Life Investment Management
LLC, its affiliates, or third-party service providers, as compensation for
services rendered to shareholders of Class R1 or Class R2 shares, a shareholder
service fee.

The Fund's investment objective is to seek long-term appreciation of capital.
The Fund also seeks to earn income, but this is a secondary objective.

The Fund invests in foreign securities which carry certain risks that are in
addition to the usual risks inherent in domestic instruments. These risks
include those resulting from currency fluctuations, future adverse political and
economic developments and possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. These risks are likely to be
greater in emerging markets than in developed markets. The ability of issuers of
debt securities held by the Fund to meet their obligations may be affected by
economic and political developments in a specific country, industry or region.

NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on the valuation date; such securities not
traded on the valuation date are valued at the mean of the latest quoted bid and
asked prices. Prices normally are taken from the principal market in which each
security trades. Debt securities are valued at prices supplied by a pricing
agent or brokers selected by the Fund's Manager, whose prices reflect
broker/dealer supplied valuations and electronic data processing techniques, if
such prices are deemed by the Fund's Manager to be representative of market
values, at the regular close of business of the New York Stock Exchange.
Temporary cash investments acquired over 60 days to maturity are valued using
the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments are valued at amortized cost, which approximates market value.
Securities for which market quotations are not readily available are valued by
methods deemed in good faith by Board of Trustees to represent fair value.
Reasons for which securities may be valued in this manner include, but are not
limited to, trading for a security has been halted or suspended, a security has
been de-listed from a national exchange, or trading on a security's principal
market is temporarily closed at a time when under normal conditions it would be
open. At October 31, 2005, the Fund did not hold securities that were valued in
such a manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor conclude that such events may have effected the accuracy
of the last price reported on the local foreign market, the Manager or
Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of
the local price to reflect the impact on the price of such securities as a
result of such events.

(B) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all

                                                    www.MAINSTAYfunds.com     23

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

times to the market value of the securities loaned. The Fund may bear the risk
of delay in recovery of, or loss of rights in, the securities loaned should the
borrower of the securities experience financial difficulty. The Fund receives
compensation for lending its securities in the form of fees or it retains a
portion of interest on the investment of any cash received as collateral. The
Fund also continues to receive interest and dividends on the securities loaned
and any gain or loss in the market price of the securities loaned that may occur
during the term of the loan will be for the account of the Fund. (See Note 7).

(C) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are withheld at the source.

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
quarterly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

The following table discloses the current period reclassification between
undistributed net investment income, accumulated net realized gain on
investments and additional paid-in capital arising from permanent differences;
net assets at October 31, 2005, are not affected.

<Table>
<Caption>
                        ACCUMULATED
     UNDISTRIBUTED     NET REALIZED
    NET INVESTMENT          GAIN ON        ADDITIONAL
            INCOME      INVESTMENTS   PAID-IN-CAPITAL
                                
    $      (21,795)  $       55,322   $       (33,527)
</Table>

The reclassification for the Fund is primarily due to the fact that net
operating losses cannot be carried forward for federal income tax purposes,
foreign currency gain (loss), real estate investment trusts investments and
distributions paid in connection with the redemption of Fund shares.

(E) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on securities, other than short-term securities,
purchased for the Fund are accreted and amortized, respectively, on the constant
yield method over the life of the respective securities or, in the case of a
callable security, over the period to the first date of call. Discounts and
premiums on short-term securities are accreted and amortized, respectively, on
the straight line method. Income from payment-in-kind securities is recorded
daily based on the effective interest method of accrual.

The investment income and realized and unrealized gains and losses on
investments of the Fund are allocated to separate classes of shares based upon
their relative net assets on the date the income is earned or realized and
unrealized gains and losses are incurred.

(F) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at
the mean between the buying and selling rates last quoted by any major U.S. bank
at the following dates:

(i)  market value of investment securities, other assets and liabilities -- at
     the valuation date,

(ii) purchases and sales of investment securities, income and expenses -- at the
     date of such transactions.

The assets and liabilities are presented at the exchange rates and market values
at the close of the period. The realized and unrealized changes in net assets
arising from fluctuations in exchange rates and market prices of securities are
not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments, are reflected in
unrealized foreign exchange gains or losses at period end exchange rates.

(G) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

 24   MainStay MAP Fund


(H) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(I) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3 -- FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. Markston
International LLC and Jennison Associates LLC (the "Subadvisors") will each
manage a portion of the Fund's assets, as designated by NYLIM from time to time,
subject to the oversight of NYLIM. Each Subadvisor is responsible for the
day-to-day portfolio management of the Fund with respect to its allocated
portion of the Fund's assets.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.75% on assets up to $1.0 billion and
0.70% on assets in excess of $1.0 billion. Effective August 1, 2005, the Manager
has entered into a written expense limitation agreement, under which the Manager
has agreed to reimburse the expenses of the Fund so that the total operating
expenses (excluding taxes, interest, litigation, extraordinary expenses, and
brokerage and other transaction expenses relating to the purchase or sale of
portfolio investments) do not exceed, on an annualized basis, 1.35% of the
average daily net assets of the Class A shares. An equivalent reimbursement, in
an equal amount of basis points, will be applied to the other share classes. The
Manager, within three years of incurring such expenses, may recoup the amount of
any management fee waiver or expense reimbursement from the Fund pursuant to
this agreement if such recoupment does not cause the Fund to exceed the expense
limitations. At October 31, 2005, the Fund had $222,593 of recoupment available.
This amount is available until October 31, 2008. This expense limitation may be
modified or terminated only with the approval of the Board of Trustees. Prior to
August 1, 2005, the Manager had agreed to voluntarily reimburse the expenses of
the Fund so that total annual fund operating expenses do not exceed on an
annualized basis 1.35% of the average daily net assets of the Class A shares,
and such that there would be an equivalent reduction for the other classes of
shares. For the year ended October 31, 2005, the Manager earned fees from the
Fund in the amount of $8,674,774 and waived its fees and/or reimbursed expenses
in the amount of $237,690.

Pursuant to the terms of a Sub-Advisory Agreement between the Manager and the
Subadvisors, the Manager pays the Subadvisors a monthly fee at an annual rate of
the Fund's average daily net assets of 0.45% on assets up to $250 million, 0.40%
on assets from $250 million to $500 million and 0.35% on assets in excess of
$500 million.

(B) DISTRIBUTION, SERVICE AND SHAREHOLDER SERVICE FEES.  The Trust, on behalf of
the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund,
with respect to Class A, Class B, Class C, and Class R2 shares, has adopted
distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1
under the 1940 Act. Pursuant to the Class A and Class R2 Plan, the Distributor
receives a monthly fee from the Fund at an annual rate of 0.25% of the average
daily net assets of the Fund's Class A and Class R2 shares, which is an expense
of the Class A and Class R2 shares of the Fund for distribution or service
activities as designated by the Distributor. Pursuant to the Class B and Class C
Plans, the Fund pays the Distributor a monthly fee, which is an expense of the
Class B and Class C shares of the Fund, at the annual rate of 0.75% of the
average daily net assets of the Fund's Class B and Class C shares. The Plans
provide that the Class B and Class C shares of the Fund also incur a service fee
at the annual rate of 0.25% of the average daily net asset value of the Class B
or Class C shares of the Fund. Class I shares are not subject to a distribution
or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

The Fund has adopted a shareholder services plan with respect to Class R1 and
Class R2 shares. 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

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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 $267,758 for the year
ended October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $3,715, $459,520 and $19,712, respectively, for the year ended October
31, 2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund for the year ended
October 31, 2005, amounted to $2,938,196.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus the Fund only pays a
portion of the fees identified above.

(F) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$31,351 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $143,449 for the year ended
October 31, 2005.

NOTE 4 -- CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, The Bank of New York acted as custodian for the Fund.

NOTE 5 -- FEDERAL INCOME TAX:

As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis
were as follows:

NOTE 10 -- OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters, NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those arrangements and certain other levels of trading
by fund shareholders over the period from 1999 to 2003 may have had on the
funds. As a result of this review in December 2005, NYLIM made payments totaling
$5.9 million to nine MainStay funds. No payment was made with respect to the
MainStay MAP Fund. NYLIM has also agreed to reimburse or pay all expenses
relating to the 'Board of Trustees' review of this matter, and has paid
substantially all of the costs associated with the other regulatory matters
described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay MAP Fund ("the Fund"), one of the
funds constituting The MainStay Funds, as of October 31, 2005, and the related
statement of operations for the year then ended, and the statements of changes
in net assets and financial highlights for each of the years in the two-year
period then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the periods presented through October 31,
2003, were audited by other auditors, whose report dated December 18, 2003,
expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay MAP Fund of The MainStay Funds as of October 31, 2005, the results of
its operations for the year then ended, and the changes in its net assets and
financial highlights for each of the years in the two-year period then ended, in
conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreements, the Trustees requested and received from the Manager and
Subadvisors, and reviewed, a wide variety of information. The Trustees also
requested and received information from outside data providers and information
and analysis from a third party consultant. The Trustees considered various
industry and regulatory trends in their deliberations. In considering approval
of these Agreements, and in evaluating the fairness of the compensation to be
paid by the Fund, the Trustees met a number of times as a full Board and in
executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisors. The Trustees reviewed the services
that the Manager and Subadvisors have provided historically to the Fund, and
also generally to other series of the Trust. The Manager's services to the Trust
have included investment management services, including the selection and
supervision of portfolio managers or subadvisers, and administrative services,
including interacting with other service providers to the Trust, maintaining
certain Fund records, providing office space, performing clerical and
bookkeeping services for the Fund, preparing Fund filings, and other
administrative services. The Subadvisors' services have included, among other
things, providing the day-to-day management of the portfolio, providing reports
to the Manager, and reviewing certain aspects of Fund filings. The Trustees
discussed with the Manager the proportion of the portfolio managed by each
Subadvisor and each Subadvisor's capacity with respect to managing assets of the
Fund. The Trustees considered, among other things, the Manager's and
Subadvisors' management, personnel, resources, operations and portfolio
management capabilities. In considering the Manager's and Subadvisors' practices
relating to best execution of portfolio trades, the Board reviewed reports of
the Fund's Brokerage Committee including with respect to analysis prepared by
Plexus Group. The Trustees considered the Manager's supervision of the Fund's
service providers and its attention to the compliance program of the Trust, the
Manager, the Subadvisors and certain other service providers, as well as each
Subadvisor's attention to its compliance program. The Trustees noted the
generally favorable conclusions of financial services research firm DALBAR Inc.
of the services, investor complaint levels, and communications that NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of the Manager, has provided
to Trust shareholders. A majority of the Trustees, including a majority of the
Non-Interested Trustees, concluded that, overall, the nature, extent and quality
of the services expected to be provided by the Manager and Subadvisors were such
that, in the context of the Board's overall review of various factors, the
Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's competitive performance over
several periods and particularly over five years. In addition, the Board
considered each Subadvisor's performance and complementary investment processes
and styles, and the Manager's oversight role, including with respect to
allocating the Fund's assets between the portfolios managed by the two
Subadvisors. The Trustees reviewed information about such options as adding a
new subadviser in the event that the Fund's assets significantly increase in
size or applying to the SEC for an exemption to allow the hiring and replacement
of multiple subadvisers without the requirement of obtaining shareholder
approval for each such hiring and replacement. There is no assurance that the
Fund will seek such an exemption or, if sought, that the SEC would grant an
order providing such an exemption.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees noted the Manager's agreement to limit the Fund's net
expenses to a certain level with respect to the Fund, with the expectation that
the Manager intended, over time, to implement measures designed to reduce the
Trust's transfer agency fees. The Trustees considered certain benefits expected
for, and risks borne by, the Manager and its affiliates, including benefits from
soft dollar arrangements. The Trustees considered the services provided to the
Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under
other agreements, and the benefits to the Manager and its affiliates from those
relationships. The information provided to the Trustees indicated that the
profitability to the Manager and its affiliates arising directly from those
other agreements was not excessive. The

 32   MainStay MAP Fund


Trustees acknowledged certain benefits to the reputation of the Manager and its
affiliates, as well to that of the Trust, from their association with each
other.

The Trustees, in reviewing economies of scale, noted the substantial growth of
the Fund over the past five years. The Trustees discussed the extent to which
economies of scale were projected by the Manager to be realized if the Fund
continues to grow, or as the Trust grows overall, noting in particular the
Manager's plans for marketing and distributing shares of various series of the
Trust. They noted the Manager's willingness to implement contractual
breakpoints, and that the contractual breakpoints in place for the management
fee were intended to provide that the Fund's shareholders would share in
benefits from economies of scale arising from the growth of Fund assets. The
Trustees noted that the Fund's contractual management fee had been reduced in
accordance with the terms of the breakpoint schedule applicable to the Fund.
Acknowledging the difficulty of forecasting economies of scale, the Trustees
generally expressed an intention to monitor the Manager's profitability and
consider the application of fee breakpoints or other appropriate measures as the
Board may determine from time to time. The Trustees reviewed historical
information about changes in the Fund's expense and asset levels over time, as
well as information about certain Fund expenses that would remain fixed even as
Fund assets increase and, therefore, provide the Fund with benefits from
economies of scale as the Fund grows. The Trustees noted that, to the extent the
Fund's gross expenses currently are higher than its net expenses, economies of
scale achieved through an increase in the Fund's assets might not directly
benefit the Fund through lower net expenses. The Trustees considered various
information about transfer agency expenses, including information showing that
transfer agency fees of a significant number of series of the Trust (although
not every such series or with respect to every share class of each series)
tended to be high, when aggregated and expressed as a percentage of the assets
of certain series, compared to the mutual fund industry average according to
certain studies reviewed by the Board and, therefore, adversely affected gross
expense ratios. The Board received information about potential effects on the
Manager were it to subsidize certain portions of the Trust's transfer agency
fees. The Trustees noted that a significant number of shareholders of the
Trust's series had small amounts invested in the series, and have considered
measures intended to increase average shareholder account size and/or otherwise
reduce the Trust's transfer agency fees and expenses, including steps that the
Manager has taken to encourage shareholders to consolidate or close small
accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager, including other registered funds and separate
institutional accounts, that had investment objectives similar to that of the
Fund. The Trustees took into account information provided by the Manager about
the relative scope of services provided to the Fund and to those accounts or
explanations about the accounts' histories. In considering the extent of the
fees received by the Manager for providing services to the Fund, the Trustees
evaluated factors such as the fees and expenses borne by other registered funds
in the market pursuing strategies generally similar to those followed by the
Fund. The Trustees considered the Fund's historical and proposed contractual and
net management fees, its anticipated gross and net expense ratios, and various
components of that expense ratio, in comparison to other funds in comparison
groupings prepared by outside data providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisors and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

                    Annual Report

                    October 31, 2005


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.
At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/S/ CHRISTOPHER O. BLUNT


Christopher O. Blunt
President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 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. The fee waivers and/or expense limitations are contractual and
may be modified or terminated only with the approval of the Board of Trustees.
From inception (5/1/86) through 12/31/94 (for Class A, first offered 1/3/95),
8/31/98 (for Class C, first offered 9/1/98), and 12/31/03 (for Class I, first
offered 1/2/04), performance of Class A, 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 A, C, and I shares.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY GOVERNMENT FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balance or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

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 0.67% for Class I)
   multiplied by the average account value over the period, divided by 365,
   multiplied by 184 (to reflect the one-half year period).

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Gary Goodenough, Joseph Portera, and
Jeffrey H. Saxon of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in U.S. government
securities. It may invest up to 20% of its assets in mortgage-related and
asset-backed securities or other securities that are not U.S. government
securities. In implementing this strategy, we use a combined approach to
investing. We analyze economic trends as well as factors pertinent to particular
issuers and securities. The Fund's principal investments include U.S. Treasury
bills, notes, and bonds, Ginnie Mae certificates, and other U.S. government
securities representing ownership interests in mortgage pools, such as
securities issued by Fannie Mae and Freddie Mac. We may sell securities when the
condition of the economy, meaningful changes in an issuer's condition, or other
factors suggest that the securities will no longer contribute to the Fund's
ability to meet its investment objective.

WHAT ECONOMIC FORCES AFFECTED THE BOND MARKET DURING THE 12 MONTHS ENDED OCTOBER
31, 2005?

Debate over the lasting effects of higher energy costs continued, with aggregate
demand and inflation among the key concerns. Noting that "higher energy and
other costs have the potential to add to inflation pressures," the Federal Open
Market Committee raised the targeted federal funds rate to 3.75% on September
20, 2005. The move was the FOMC's eighth 25-basis-point increase during the
12-month reporting period. (A basis point is one-hundredth of a percentage
point.) Since rebuilding activity following hurricanes Katrina and Rita may
stimulate the economy, money-market futures anticipate that additional
interest-rate hikes may be needed to keep inflation in check.

HOW DID THE TREASURY YIELD CURVE CHANGE DURING THE REPORTING PERIOD?

From October 29, 2004, to October 31, 2005, the two-year Treasury yield advanced
183 basis points (from 2.56% to 4.38%). Over the same period, five-year Treasury
yields increased 116 basis points (from 3.29% to 4.45%) and 10-year Treasury
yields rose 53 basis points (from 4.03% to 4.56%). On the other hand, 30-year
Treasury yields declined four basis points (from 4.79% to 4.75%).(1)

With Federal Reserve action pushing short-term interest rates higher and
foreign-investors supporting long bonds, the yield curve flattened
substantially. The spread between two-year and 30-year Treasurys narrowed 186
basis points.

HOW DID YOU POSITION THE PORTFOLIO ACROSS THE VARIOUS BOND SECTORS AVAILABLE TO
THE FUND?

At the end of October 2005, the Fund held approximately 5% of its net assets in
Treasurys, 27% in agency debentures, 55% in residential mortgage-backed
securities issued by government-sponsored and government-related enterprises, 5%
in asset-backed securities, 6% in commercial mortgage-backed securities, and 2%
in investment-grade corporate bonds.

During the reporting period, we favored securitized products for their
relatively high credit quality, liquidity, and incremental yield. We diversified
the Fund's holdings in securitized issues across residential mortgage-backed,
commercial mortgage-backed, and asset-backed securities.

DID YOU MAKE ANY CHANGES TO THE FUND'S ALLOCATION DURING THE REPORTING PERIOD?

In prior periods, we used prepayments from mortgage-backed and asset-backed
bonds to repurchase securities in the respective sectors. During the reporting
period, we had two reasons for deciding to use such proceeds in other ways.
First, we wanted to pare back the Fund's exposure to the mortgage-backed and
asset-backed sectors because we felt that interest-rate volatility might
increase during the Federal Reserve's tightening cycle. Second, we wanted to
offset some of the Fund's extension risk--or the risk that rising rates might
cause mortgage-backed securities to extend the Fund's duration.

During the reporting period, we also added incremental yield by rotating 10% of
the Fund's assets from Treasurys into agency debentures. We added a 1% position
in Treasury Inflation-Protected Securities (TIPS) to capitalize on higher energy
prices. To trim credit risk, we shifted 1% of the Fund's net assets out of
corporate bonds and asset-backed securities into commercial mortgage-backed
securities.


Investments in the Fund are not guaranteed, even though some of the Fund's
investments are guaranteed by the U.S. government or its agencies or
instrumentalities. The Fund may invest in derivatives, which may increase the
volatility of the Fund's net asset value and may result in a loss to the Fund.
The Fund may experience a portfolio turnover rate of over 100% and may generate
short- term capital gains which are taxable. Funds that invest in bonds are
subject to interest-rate risk and can lose principal value when interest rates
rise and may generate short-term capital gains.

HOW DID YOU MANAGE THE FUND'S DURATION DURING THE REPORTING PERIOD?

We try to maintain the Fund's average duration between 3.75 and 4.25 years, a
range that we believe is consistent with the Fund's peers. On October 31, 2005,
the Fund's duration was 4.22 years. This is close to the top of the range and
nearly a half year longer than the Fund's duration when the 12-month reporting
period began. As we had anticipated, rising mortgage rates slowed prepayments of
the loans that collateralize the Fund's mortgage-backed securities, which caused
the Fund's duration to lengthen during the reporting period.

WHAT OTHER DECISIONS HAD A POSITIVE IMPACT ON THE FUND'S PERFORMANCE DURING THE
REPORTING PERIOD?

The Fund benefited from our efforts to take advantage of a flattening Treasury
yield curve. We increased the Fund's long-term exposure by adding long-dated
agency debentures that offered a yield advantage over Treasury bonds. The Fund's
agency debentures also generated attractive excess returns when compared to
Treasury securities with similar durations. We also managed the Fund's mortgage-
related extension risk by overweighting mortgage-backed securities that are less
sensitive to prepayments. Finally, the Fund's position in Treasury
Inflation-Protected Securities outperformed similar-duration Treasurys when the
price of crude oil spiked.

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
Government Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares, whose
distribution commenced on January 3, 1995, are offered at net asset value per
share plus an initial sales charge. No sales charge applies on investments of $1
million or more (and certain other qualified purchases) in Class A shares, but a
contingent deferred sales charge is imposed on certain redemptions of such
shares within one year of the date of purchase. Class B shares and Class C
shares are offered without an initial sales charge, although a declining
contingent deferred sales charge may be imposed on redemptions made within six
years of purchase of Class B shares and within one year of purchase of Class C
shares. Distribution of Class B shares and Class C shares commenced on May 1,
1986 and September 1, 1998, respectively. Class I shares are not subject to
sales charge. Distribution of Class I shares commenced on January 2, 2004. Class
A shares, Class B shares, Class C shares and Class I shares bear the same voting
(except for issues that relate solely to one class), dividend, liquidation and
other rights and conditions. Each class of shares other than Class I shares
bears distribution and/or service fee payments under a distribution plan
pursuant to Rule 12b-1 under the 1940 Act. Class I shares are not subject to a
distribution or service fee.

The Fund's investment objective is to seek a high level of current income,
consistent with safety of principal.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or brokers selected by the Fund's Manager, whose prices reflect
broker/dealer supplied valuations and electronic data processing techniques, if
such prices are deemed by the Fund's Manager to be representative of market
values, at the regular close of business of the New York Stock Exchange.
Temporary cash investments acquired over 60 days to maturity are valued using
the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments are valued at amortized cost, which approximates market value.
Securities for which market quotations are not readily available are valued by
methods deemed in good faith by Board of Trustees to represent fair value.
Reasons for which securities may be valued in this manner include, but are not
limited to, trading for a security has been halted or suspended, a security has
been de-listed from a national exchange, or trading on a security's principal
market is temporarily closed at a time when under normal conditions it would be
open. The Fund did not hold securities at October 31, 2005, that were valued in
such manner.

(B) MORTGAGE DOLLAR ROLLS.  The Fund enters into mortgage dollar roll ("MDR")
transactions in which it sells mortgage-backed securities ("MBS") from its
portfolio to a counterparty from whom it simultaneously agrees to buy a similar
security on a delayed delivery basis. The MDR transactions of the Fund are
classified as purchase and sale transactions. The securities sold in connection
with the MDRs are removed from the portfolio and a realized gain or loss is
recognized. The securities the Fund has agreed to acquire are included at market
value in the portfolio of investments and liabilities for such purchase
commitments are included as payables for investments purchased. During the roll
period, a Fund forgoes principal and interest on the securities. A Fund is
compensated by the difference between the current sales price and the forward
price for the future purpose as well as by the earnings on the cash proceeds of
the initial sale. MDRs may be renewed without physical delivery of the
securities subject to the contract. The Fund maintains a segregated account with
its custodian containing securities from its portfolio having a value not less
than the repurchase price, including accrued interest. MDR transactions involve
certain risks, including the risk that the MBS returned to the Fund at the end
of the roll, while substantially similar, could be inferior to what was
initially sold to the counterparty.

(C) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See Note 7.)

 18   MainStay Government Fund


(D) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are withheld at the source.

(E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
monthly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

The following table discloses the current year reclassifications between
distributions in excess of net investment income, net realized loss and
additional paid-in capital arising from permanent differences; net assets at
October 31, 2005 are not affected.

<Table>
<Caption>
             UNDISTRIBUTED   ACCUMULATED NET REALIZED
     NET INVESTMENT INCOME        LOSS ON INVESTMENTS
                          
         $545,696                   $ (545,696)
 ----------------------------------------------------
</Table>

The reclassification for the Fund is primarily due to paydowns.

(F) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method and includes gains
and losses from repayments of principal on mortgage-backed securities. Interest
income is accrued as earned. Discounts and premiums on securities, other than
short-term securities, purchased for the Fund are accreted and amortized,
respectively, on the constant yield method over the life of the respective
securities or, in the case of a callable security, over the period to the first
date of call. Discounts and premiums on short-term securities are accreted and
amortized, respectively, on the straight line method. Income from
payment-in-kind securities is recorded daily based on the effective interest
method of accrual.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(G) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(H) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(I) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

                                                    www.MAINSTAYfunds.com     19

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.60% on assets up to $1 billion and 0.55%
on assets in excess of $1 billion. In addition, effective August 1, 2004, NYLIM
voluntarily agreed to waive its management fee by 0.10% on assets up to $1
billion and 0.45% on assets in excess of $1 billion. Effective August 1, 2005,
the Manager has entered into a written expense limitation agreement, under which
the Manager has agreed to reimburse the expenses of the Fund so that the total
operating expenses (excluding taxes, interest, litigation, extraordinary
expenses, and brokerage and other transaction expenses relating to the purchase
or sale of portfolio investments) do not exceed, on an annualized basis, 1.05%
of the average daily net assets of the Class A shares. An equivalent
reimbursement, in an equal amount of basis points, will be applied to the other
share classes. The Manager, within three years of incurring such expenses, may
recoup the amount of any management fee waiver or expense reimbursement from the
Fund pursuant to this agreement if such recoupment does not cause the Fund to
exceed the expense limitations. At October 31, 2005, the Fund had $302,892 of
recoupment available. This amount is available until October 31, 2008. This
expense limitation may be modified or terminated only with the approval of the
Board of Trustees. Prior to August 1, 2005 and after December 1, 2004, NYLIM had
agreed to voluntarily reimburse the expenses of the Fund so that the total
operating expenses would not exceed on an annualized basis 1.05% of the average
daily net assets of the Class A shares, and such that there would be an
equivalent reduction for the other classes of shares. For the year ended October
31, 2005, the Manager earned fees from the Fund in the amount of $2,375,635, and
waived its fee and/or reimbursed expenses in the amount of $1,157,488.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager pays the Subadvisor a monthly fee of 0.30% of the Fund's
average daily net assets on assets up to $1 billion and 0.275% on assets in
excess of $1 billion. To the extent the Manager has agreed to reimburse expenses
of the Fund, the Subadvisor has voluntarily agreed to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from
the Fund at an annual rate of 0.25% of the average daily net assets of the
Fund's Class A shares, which is an expense of the Class A shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The Plans provide that the Class B and Class C shares of the Fund also
incur a service fee at the annual rate of 0.25% of the average daily net asset
value of the Class B or Class C shares of the Fund. Class I shares are not
subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $23,490 for the year ended
October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $6,500, $215,418 and $1,780, respectively, for the year ended October
31, 2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund for the year ended
October 31, 2005, amounted to $1,520,220.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective

 20   MainStay Government Fund


Funds. Thus the Fund only pays a portion of the fees identified above.

F) CAPITAL.  At October 31, 2005, New York Life and its affiliates held shares
of Class I with a net asset value of $1,009. This represents 6.2% of the Class I
shares net assets and less than one-tenth of one percent of the Fund's total net
assets at October 31, 2005.

(G) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$10,303 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $66,261 for the year ended
October 31, 2005.

NOTE 4--CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, State Street Bank and Trust Company acted as custodian for
the Fund.

NOTE 5--FEDERAL INCOME TAX:

As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis
were as follows:

 -----------------------------------------------------------------------
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to premium amortization adjustments.

At October 31, 2005, for federal income tax purposes, capital loss carryforwards
of $39,793,212 were available as shown in the table below, to the extent
provided by the regulations to offset future realized gains of the Fund through
the years indicated. To the extent that these loss carryforwards are used to
offset future capital gains, it is probable that the capital gains so offset
will not be distributed to shareholders.

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

NOTE 10--OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those arrangements and certain other levels of trading
by fund shareholders over the period from 1999 to 2003 may have had on the
funds. As a result of this review in December 2005, NYLIM made payments totaling
$5.9 million to nine MainStay funds. No payment was made with respect to the
MainStay Government Fund. NYLIM has also agreed to reimburse or pay all expenses
relating to the Board of Trustees' review of this matter and has paid
substantially all of the costs associated with the other regulatory matters
described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Government Fund ("the Fund"), one
of the funds constituting The MainStay Funds, as of October 31, 2005, and the
related statement of operations for the year then ended, and the statements of
changes in net assets and financial highlights for each of the years in the
two-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Government Fund of The MainStay Funds as of October 31, 2005, the
results of its operations for the year then ended, and the changes in its net
assets and financial highlights for each of the years in the two-year period
then ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreement, the Board of Trustees requested and received from the
Manager and Subadvisor, and reviewed, a wide variety of information. The
Trustees also requested and received information from outside data providers and
information and analysis from a third party consultant. The Trustees considered
various industry and regulatory trends in their deliberations. In considering
approval of these Agreements, and in evaluating the fairness of the compensation
to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and Subadvisor have provided historically to the Fund, and also
generally to other series of the Trust. The Manager's services to the Trust have
included investment management services, including the selection and supervision
of portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the
day-to-day management of the portfolio, providing reports to the Manager, and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. In considering the Manager's
and Subadvisor's practices relating to best execution of portfolio trades, the
Board reviewed reports of the Fund's Brokerage Committee including with respect
to analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager, the Subadvisor and certain other service
providers, as well as the Subadvisor's attention to its compliance program. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager and Subadvisor were such that, in the context of the Board's overall
review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's underperformance when compared
over several time periods with funds concluded by Trustees to be peers of the
Fund, and the means outlined by the Manager and the Subadvisor to the Board
designed to address the Fund's comparative performance.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees noted the Manager's
agreement to limit the Fund's net expenses to a certain level with respect to
the Fund, with the expectation that the Manager intended, over time, to
implement measures designed to reduce the Trust's transfer agency fees. The
Trustees considered certain benefits expected for, and risks borne by, the
Manager and its affiliates, including benefits from soft dollar arrangements.
The Trustees considered the services provided to the Fund by affiliates of the
Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the
benefits to the Manager and its affiliates from those relationships. The
information provided to the Trustees indicated that the profitability to the
Manager and its affiliates arising directly from those other agreements was not
excessive. The Trustees acknowledged certain benefits to the reputation of the
Manager and its affiliates, as well to that of the Trust, from their association
with each other.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund grows, or as the Trust grows overall,
noting in particular the Manager's plans for marketing and distribut-

                                                    www.MAINSTAYfunds.com     27


ing shares of various series of the Trust. They noted the Manager's willingness
to implement contractual breakpoints, and that the contractual breakpoints in
place for the management fee were intended to provide that the Fund's
shareholders would share in benefits from economies of scale arising from the
growth of Fund assets. The Trustees acknowledged that the Fund had not yet
reached the asset level at which breakpoints would reduce the contractual
management fee to which the Fund is subject. Acknowledging the difficulty of
forecasting economies of scale, the Trustees generally expressed an intention to
monitor the Manager's profitability and consider the application of fee
breakpoints or other appropriate measures as the Board may determine from time
to time. The Trustees reviewed historical information about changes in the
Fund's expense and asset levels over time, as well as information about certain
Fund expenses that would remain fixed even as Fund assets increase and,
therefore, provide the Fund with benefits from economies of scale as the Fund
grows. The Trustees noted that, to the extent the Fund's gross expenses
currently are higher than its net expenses, economies of scale achieved through
an increase in the Fund's assets might not directly benefit the Fund through
lower net expenses. The Trustees considered various information about transfer
agency expenses, including information showing that transfer agency fees of the
Fund and a significant number of series of the Trust (although not every such
series or with respect to every share class of each series) tended to be high,
when aggregated and expressed as a percentage of the assets of certain series,
compared to the mutual fund industry average according to certain studies
reviewed by the Board and, therefore, adversely affected gross expense ratios.
The Board received information about potential effects on the Manager were it to
subsidize certain portions of the Trust's transfer agency fees. The Trustees
noted that a significant number of shareholders of the Trust's series had small
amounts invested in the series, and have considered measures intended to
increase average shareholder account size and/or otherwise reduce the Trust's
transfer agency fees and expenses, including steps that the Manager has taken to
encourage shareholders to consolidate or close small accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts, that had investment objectives similar to
that of the Fund. The Trustees took into account information provided by the
Manager or Subadvisor about the relative scope of services provided to the Fund
and to those accounts or explanations about the accounts' histories. In
considering the extent of the fees received by the Manager and Subadvisor for
providing services to the Fund, the Trustees evaluated factors such as the fees
and expenses borne by other registered funds in the market pursuing strategies
generally similar to those followed by the Fund. The Trustees considered the
Fund's historical and proposed contractual and net management fees, its
anticipated gross and net expense ratios, and various components of that expense
ratio, in comparison to other funds in comparison groupings prepared by outside
data providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

                    Annual Report

                    October 31, 2005


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.
At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/s/ Christopher O. Blunt


Christopher O. Blunt
President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 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. From inception (5/1/86) through
12/31/94 (for Class A, first offered 1/3/95), 8/31/98 (for Class C, first
offered 9/1/98), and 12/31/03 (for Class I, first offered 1/2/04), performance
of Class A, C, and I shares includes the historical performance of Class B
shares adjusted to reflect the applicable sales charge (or CDSC) and fees and

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY HIGH YIELD CORPORATE BOND
FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six-months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

   multiplied by the average account value over the period, divided by 365,
   multiplied by 184 (to reflect the one-half year period).

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Donald E. Morgan and J. Matthew Philo
of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in high-yield corporate
debt securities, including all types of high-yield domestic and foreign
corporate debt securities that are rated below investment grade by Moody's or
S&P or, if unrated, that we consider to be of comparable quality. In
implementing this strategy, we seek to identify investment opportunities based
primarily on the financial condition and competitiveness of individual
companies. The Fund's principal investments include domestic corporate debt
securities, Yankee or dollar-denominated debt securities, zero coupon bonds,
U.S. government securities, convertible corporate bonds, and loan participation
interests. The Fund may invest up to 20% of its assets in equity securities and
may invest up to 20% of its net assets in securities rated lower than B by
Moody's and S&P.(1)

WHAT WERE SOME OF THE TRENDS THAT DROVE THE HIGH-YIELD MARKET DURING THE 12
MONTHS ENDED OCTOBER 31, 2005?

Despite periods of volatility, the high-yield market generated positive results
during the reporting period. The most significant factor facing the market was
the tight yield spread(2) between high-yield bonds and U.S. Treasury bonds. This
may perhaps account for the flow of funds away from high-yield mutual funds
during the reporting period. High-yield default rates have remained at
historical lows. For the first 10 months of 2005, the high-yield new-issue
market slowed from its record pace in 2004. We believe that the overall quality
of new issues has declined.

WHAT EFFECT DID THESE MARKET TRENDS HAVE ON THE FUND?

Traditionally, high-yield bond spreads reflect the amount of additional yield
investors receive for assuming additional risk. In response to the low
yield-spread environment, we broadly diversified the Fund and reduced or
eliminated positions that carried higher risk. Slower new issuance and lower-
quality offerings limited a key source of new investments for the Fund. In the
wake of strong high-yield performance in 2003 and 2004, the secondary market
also provided fewer buying opportunities that we considered attractive. As a
result, cash levels in the Fund rose during the reporting period.
Higher-than-normal tenders from bond issuers have also added to the Fund's cash
level. (A tender is a payment for bonds called prior to maturity.)

HOW DID YOU POSITION THE FUND FROM AN INDUSTRY PERSPECTIVE?

We are bottom-up investors, so the Fund's exposure to various sectors and
industries is primarily the result of individual security selection. During the
12 months ended October 31, 2005, we reduced the Fund's exposure to bonds in the
utilities, cable, and broadcasting industries.(3) Over the same period, we
increased the Fund's absolute weightings in automotive, information technology,
diversified media, retail, and real estate development bonds.

At the end of the reporting period, the Fund's largest overweighted positions
relative to the Credit Suisse First Boston(TM) High Yield Index(4) were in the
information technology, financial, real estate development,


High-yield debt securities ("junk bonds") are generally considered speculative
because they present a greater risk of loss than higher- quality debt securities
and may be subject to greater price volatility. Foreign securities may be
subject to greater risks than U.S. investments, including currency fluctuations,
less-liquid trading markets, greater price volatility, political and economic
instability, less publicly available information, and changes in tax or currency
laws or monetary policy. These risks are likely to be greater in emerging
markets than in developed markets. The Fund may experience a portfolio turnover
rate of over 100% and may generate short-term capital gains, which are taxable.
Funds that invest in bonds are subject to interest-rate risk and can lose
principal value when interest rates rise.
1. Bonds rated B by Moody's Investors Service are deemed by Moody's to generally
   lack characteristics of the desirable investment. According to Moody's,
   assurance of interest and principal payments or of maintenance of other terms
   of the contract over any long period of time may be small. Debt rated B by
   Standard & Poor's is deemed by Standard & Poor's to be more vulnerable to
   nonpayment than obligations rated BB, but it is the opinion of Standard &
   Poor's that the obligor currently has the capacity to meet its financial
   commitment on the obligation. Standard & Poor's believes that adverse
   business, financial, or economic conditions will likely impair the obligor's
   capacity or willingness to meet its financial commitment on the obligation.
   When applied to Fund holdings, ratings are based solely on the
   creditworthiness of the bonds in the portfolio and are not meant to represent
   the security or safety of the Fund.
2. The terms "spread" and "yield spread" may refer to the difference in yield
   between a specific security or type of security and comparable U.S. Treasury
   issues. The terms may also refer to the difference in yield between two
   specific securities or types of securities at a given time.
3. Industries mentioned in the Portfolio Management Discussion and Analysis are
   those included in the Credit Suisse First Boston(TM) High Yield Index.
   Industries in the Portfolio of Investments reflect the Global Industry
   Classification Standard (GICS) developed by Standard & Poor's and MSCI.

packaging, and medical products industries. At the same time, the Fund held
underweighted positions relative to the Index in gaming, utility, manufacturing,
consumer non-durables, and food and drug bonds.

DID YOU ADJUST THE FUND'S DURATION POSITIONING DURING THE REPORTING PERIOD?

As bottom-up investors, duration is primarily a residual of our investment
process. We believe that high-yield bonds have risk and reward characteristics
similar to those of equities. As a result, traditional fixed-income strategies,
such as yield-curve positioning, maturity structure, and duration management are
not the focal point of our investment process. That said, we believe that our
general duration parameters of plus or minus 10% relative to the benchmark index
may serve to reduce the duration risk of the Fund. The duration of the
high-yield market has historically fluctuated around four years. This is true
for several reasons. Coupons are generally higher than those of investment-grade
fixed-income securities, few high-yield bonds are issued with maturities of 15
or more years, and call provisions often allow for refinancing. Given the
low-spread and rising-rate environment during the reporting period, the Fund has
had a shorter duration than its benchmark index.

WHICH SECURITIES WERE STRONG AND WEAK PERFORMERS DURING THE REPORTING PERIOD?

The Fund's top performers included At Home, UnitedGlobalCom, ICO Global
Communications Holdings, President Casinos, and General Motors Acceptance Corp.
The Fund's weak performers included Collins & Aikman Products, Northwest
Airlines, Delta Air Lines, Globix Corp., and Abitibi-Consolidated.

At Home, an Internet service provider that filed for bankruptcy protection in
2001, had partnered with several prominent cable partners, the largest of which
was AT&T. The company reached a substantial settlement with AT&T weeks before a
major lawsuit was to go to trial. This resulted in a significant award that
helped the Fund's performance.

While the market had priced in the possibility of defaults before Delta Air
Lines and Northwest Airlines filed for bankruptcy in September 2005, the airline
industry as a whole showed poor performance during the reporting period. Rising
oil prices and their impact on the cost of jet fuel drove the Fund's investments
in Delta Air Lines and Northwest Airlines downward. The Fund continues to hold
Delta and Northwest because we see attractive value in these companies relative
to their current trading levels.

Bonds of automakers General Motors and Ford Motor traded at yields comparable to
high-yield issuers for several months before both companies faced credit
downgrades by Moody's and S&P in early May 2005. We initiated a large position
in General Motors Acceptance Corp. (GMAC) earlier in 2005, before the debt was
downgraded. GMAC now constitutes a large part of the high-yield market. We view
GMAC as a separate issuer from General Motors because the companies have
distinctly separate assets covering their bonds, separate financial statements,
and separate boards. News reports that General Motors has considered selling or
spinning off GMAC have strengthened the performance of GMAC bonds.

WERE THERE ANY OTHER AREAS THAT DIDN'T MEET YOUR EXPECTATIONS?

The Fund's position in automotive interior components and systems manufacturer
Collins & Aikman Products had a significant negative impact on performance. When
the auto industry suffered in the first quarter of 2005, we met with Collins &
Aikman's management team. A few weeks after our meeting, the CEO was forced out
by the company's board and accounting irregularities were disclosed. The bonds
traded down sharply, and the company filed for bankruptcy protection.

WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD?

During the 12 months ended October 31, 2005, we established positions in General
Motors Acceptance Corp. and added to CanWest Media, Qwest Services, El
Paso/Cedar Brakes, and Qwest Communications International. Significant sales
during the reporting period included UnitedGlobalCom, El Paso/Cedar Brakes,
Hollinger Participation Trust, TSI Telecommunications, and FrontierVision
Capital Corp.

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 High
Yield Corporate Bond Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares, whose
distribution commenced on January 3, 1995, are offered at net asset value per
share plus an initial sales charge. No sales charge applies on investments of $1
million or more (and certain other qualified purchases) in Class A shares, but a
contingent deferred sales charge is imposed on certain redemptions of such
shares within one year of the date of purchase. Class B shares and Class C
shares are offered without an initial sales charge, although a declining
contingent deferred sales charge may be imposed on redemptions made within six
years of purchase of Class B shares and within one year of purchase of Class C
shares. Distribution of Class B shares and Class C shares commenced on May 1,
1986 and September 1, 1998, respectively. Class I shares are not subject to a
sales charge. Distribution of Class I shares commenced on January 2, 2004. Class
A shares, Class B shares, Class C shares and Class I shares bear the same voting
(except for issues that relate solely to one class), dividend, liquidation, and
other rights and conditions except that Class B shares and Class C shares are
subject to higher distribution fee rates than Class A shares under a
distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares are
not subject to a distribution or service fee.

The Fund's investment objective is to seek maximum income through investment in
a diversified portfolio of high yield debt securities. Capital appreciation is a
secondary objective.

The Fund invests in high yield securities (sometimes called "junk bonds"), which
are generally considered speculative because they present a greater risk of
loss, including default, than higher quality debt securities. These securities
pay a premium--a high interest rate or yield--because of the increased risk of
loss. These securities can also be subject to greater price volatility.

The Fund also invests in foreign securities which carry certain risks that are
in addition to the usual risks inherent in domestic instruments. These risks
include those resulting from currency fluctuations, future adverse political and
economic developments and possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. These risks are likely to be
greater in emerging markets than in developed markets. The ability of issuers of
debt securities held by the Fund to meet their obligations may be affected by
economic and political developments in a specific country, industry or region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or brokers selected by the Fund's Manager, whose prices reflect
broker/dealer supplied valuations and electronic data processing techniques, if
such prices are deemed by the Fund's Manager to be representative of market
values, at the regular close of business of the New York Stock Exchange. Equity
securities are valued at the latest quoted sales prices as of the close of
trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the
valuation date; such securities not traded on the valuation date are valued at
the mean of the latest quoted bid and asked prices. Prices are normally taken
from the principal market in which each security trades. Foreign currency
forward contracts are valued at their fair market values determined on the basis
of the mean between the last current bid and asked prices based on dealer or
exchange quotations. Temporary cash investments acquired over 60 days to
maturity are valued using the latest bid prices or using valuations based on a
matrix system (which considers such factors as security prices, yields,
maturities, and ratings), both as furnished by independent pricing services.
Other temporary cash investments are valued at amortized cost, which
approximates market value. Securities for which market quotations are not
readily available are valued by methods deemed in good faith by Board of
Trustees to represent fair value. Reasons for which securities may be valued in
this manner include, but are not limited to, trading for a security has been
halted or suspended, a security has been de-listed from a national exchange, or
trading on a security's principal market is temporarily closed at a time when
under normal conditions it would be open. At October 31, 2005, the Fund held
securities with a value of $27,186,592 that were valued in such manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor conclude that such events may have effected the accuracy
of the last price reported on the local foreign market, the Manager or
Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of
the local price to reflect the

 26   MainStay High Yield Corporate Bond Fund


impact on the price of such securities as a result of such events.

(B) FOREIGN CURRENCY FORWARD CONTRACTS.  A foreign currency forward contract is
an agreement to buy or sell currencies of different countries on a specified
future date at a specified rate. During the period the forward contract is open,
changes in the value of the contract are recognized as unrealized gains or
losses by "marking to market" such contract on a daily basis to reflect the
market value of the contract at the end of each day's trading. When the forward
contract is closed, the Fund records a realized gain or loss equal to the
difference between the proceeds from (or cost of) the closing transaction and
the Fund's basis in the contract. The Fund enters into foreign currency forward
contracts primarily to hedge its foreign currency denominated investments and
receivables and payables against adverse movements in future foreign exchange
rates or to try to enhance the Fund's returns.

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
period end to credit loss in the event of a counterparty's failure to perform
its obligations. (See Note 7).

(C) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See Note 7).

(D) LOAN ASSIGNMENTS, PARTICIPATIONS AND COMMITMENTS.  The Fund invests in loan
assignments and loan participations. Loan assignments and participations are
agreements to make money available (a "commitment") to a borrower in a specified
amount, at a specified rate and within a specified time. Such loan assignments
and participations are typically senior, secured and collateralized in nature.
The Fund records an investment when the borrower withdraws money and records
interest as earned. These loans pay interest at rates which are periodically
reset by reference to a base lending rate plus a spread. These base lending
rates are generally the prime rate offered by a designated U.S. bank or London
InterBank Offered Rate (LIBOR).

The loans in which the Fund invests are generally readily marketable, but may be
subject to some restrictions on resale. The Fund may be contractually obligated
to receive approval from the agent bank and/or borrower prior to the sale of
these investments.

The Fund assumes the credit risk of the Borrower, the Selling Participant and
any other persons interpositioned between the Fund and the Borrower
("Intermediate Participants"). In the event that the Borrower, Selling
Participant or Intermediate Participants becomes insolvent or enters into
bankruptcy, the Fund may incur certain costs and delays in realizing payment, or
may suffer a loss of principal and/or interest.

Unfunded commitments represent the remaining obligation of the Fund to the
Borrower. At any point in time, up to the maturity date of the issue, the
Borrower may demand the unfunded portion. These unfunded amounts are recorded in
memorandum accounts.

(E) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required. Investment income received by the Fund from foreign sources may be
subject to foreign income taxes. These foreign income taxes are withheld at the
source.

(F) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
monthly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

The following table discloses the current year reclassifications between
accumulated distributions in excess of net investment income and accumulated net
realized loss on investments arising from permanent differences; net assets at
October 31, 2005, are not affected.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

The reclassifications for the Fund are primarily due to premium amortization
adjustments and foreign currency gain (loss).

(G) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on securities, other than short-term securities,
purchased for the Fund are accreted and amortized, respectively, on the constant
yield method over the life of the respective securities or, in the case of a
callable security, over the period to the first date of call. Discounts and
premiums on short-term securities are accreted and amortized, respectively, on
the straight line method. Income from payment-in-kind securities is recorded
daily based on the effective interest method of accrual.

The investment income and realized and unrealized gains and losses on
investments of the Fund are allocated to separate classes of shares based upon
their relative net assets on the date the income is earned or realized and
unrealized gains and losses are incurred.

The Fund may place a debt obligation on non-accrual status and reduce related
interest income by ceasing current accruals and writing off interest receivables
when the collection of all or a portion of interest has become doubtful based on
consistently applied procedures. A debt obligation is removed from non-accrual
status when the issuer resumes interest payments or when collectibility of
interest is reasonably assured.

(H) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at
the mean between the buying and selling rates last quoted by any major U.S. bank
at the following dates:


(i)  market value of investment securities, other assets and liabilities--at the
     valuation date,

(ii) purchases and sales of investment securities, income and expenses--at the
     date of such transactions.

The assets and liabilities are presented at the exchange rates and market values
at the close of the period. The realized and unrealized changes in net assets
arising from fluctuations in exchange rates and market prices of securities are
not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments, are reflected in
unrealized foreign exchange gains or losses at period end exchange rates.

(I) RESTRICTED SECURITIES.  A restricted security is a security which has been
purchased through a private offering and cannot be resold to the general public
without prior registration under the Securities Act of 1933 (the "1933 Act").
The Fund does not have the right to demand that such securities be registered.
Disposal of these securities may involve time-consuming negotiations and expense
and prompt sale at an acceptable price may be difficult. (See Note 7).

(J) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(K) REDEMPTION FEE.  The Fund imposes a 2.00% redemption fee on redemptions
(including exchanges) of Fund shares made within 60 days of their date of
purchase for each class of shares. The redemption fee is designed to offset
brokerage commissions and other costs associated with short-term trading and is
not assessed on the shares acquired through the reinvestment of dividends or
distributions paid by the Fund. The redemption fees are included in the
Statement of Changes in Net Assets' shares redeemed amount and retained by the
Fund.

(L) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(M) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.60% on assets up to $500 million and
0.55% on assets in excess of $500 million. For the year ended October 31, 2005,
the Manager earned fees from the Fund in the amount of $25,241,244. It was not
necessary for the Manager to reimburse the Fund for expenses for the year ended
October 31, 2005.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager paid the Subadvisor a monthly fee of 0.30% of the Fund's
average daily net assets on assets up to $500 million and 0.275% on assets in
excess of $500 million.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from
the Fund at an annual rate of 0.25% of the average daily net assets of the
Fund's Class A shares, which is an expense of the Class A shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The Plans provide that the Class B and Class C shares of the Fund also
incur a service fee at the annual rate of 0.25% of the average daily net asset
value of the Class B or Class C shares of the Fund. Class I shares are not
subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $740,788 for the year
ended October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $48,581, $2,708,943 and $116,485, respectively, for the year ended
October 31, 2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund for the year ended
October 31, 2005, amounted to $6,603,100.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus the Fund only pays a
portion of the fees identified above.

(F) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$957,577 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

provided to the Fund by the Manager amounted to $476,386 for the year ended
October 31, 2005.

NOTE 4--CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, State Street Bank and Trust Company acted as custodian for
the Fund.

NOTE 5--FEDERAL INCOME TAX:

As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis
were as follows:

<Table>
<Caption>

 -----------------------------------------------------------------------------
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale deferrals, premium amortization adjustments, bond
reorganizations and interest write-offs.

At October 31, 2005, for federal income tax purposes, capital loss carryforwards
of $597,843,329 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.

NOTE 8--LINE OF CREDIT:

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

NOTE 10--OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the Funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those arrangements and certain other levels of trading
by fund shareholders over the period from 1999 to 2003 may have had on the
funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.9 million to nine MainStay funds. The amount paid to the MainStay
High Yield Corporate Bond Funds was $814,000. NYLIM has also agreed to reimburse
or pay all expenses relating to the Board of Trustees' review of this matter and
has paid substantially all of the costs associated with the other regulatory
matters described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that Fund as well as the related guarantee disclosure to Fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

 32   MainStay High Yield Corporate Bond Fund


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay High Yield Corporate Bond Fund
("the Fund"), one of the funds constituting The MainStay Funds, as of October
31, 2005, and the related statement of operations for the year then ended, and
the statements of changes in net assets and financial highlights for each of the
years in the two-year period then ended. These financial statements and
financial highlights are the responsibility of this Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The financial highlights for the
periods presented through October 31, 2003, were audited by other auditors,
whose report dated December 18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay High Yield Corporate Bond Fund of The MainStay Funds as of October 31,
2005, the results of its operations for the year then ended, and the changes in
its net assets and financial highlights for each of the years in the two-year
period then ended, in conformity with U.S. generally accepted accounting
principles.

 36   MainStay High Yield Corporate Bond Fund


BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreement, the Board of Trustees requested and received from the
Manager and Subadvisor, and reviewed, a wide variety of information. The
Trustees also requested and received information from outside data providers and
information and analysis from a third party consultant. The Trustees considered
various industry and regulatory trends in their deliberations. In considering
approval of these Agreements, and in evaluating the fairness of the compensation
to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and Subadvisor have provided historically to the Fund, and also
generally to other series of the Trust. The Manager's services to the Trust have
included investment management services, including the selection and supervision
of portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the
day-to-day management of the portfolio, providing reports to the Manager, and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. In considering the Manager's
and Subadvisor's practices relating to best execution of portfolio trades, the
Board reviewed reports of the Fund's Brokerage Committee including with respect
to analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager, the Subadvisor and certain other service
providers, as well as the Subadvisor's attention to its compliance program. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager and Subadvisor were such that, in the context of the Board's overall
review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's performance (top decile) when
compared over several time periods with funds concluded by Trustees to be peers
of the Fund.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees considered certain benefits
expected for, and risks borne by, the Manager and its affiliates, including
benefits from soft dollar arrangements. The Trustees considered the services
provided to the Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM
Service, under other agreements, and the benefits to the Manager and its
affiliates from those relationships. The information provided to the Trustees
indicated that the profitability to the Manager and its affiliates arising
directly from those other agreements was not excessive. The Trustees
acknowledged certain benefits to the reputation of the Manager and its
affiliates, as well to that of the Trust, from their association with each
other.

The Trustees, in considering economies of scale, noted the Fund was the largest
series of The MainStay Funds. The Trustees discussed the extent to which
economies of scale were projected by the Manager to be realized as the Fund
grows, or as the Trust grows overall, noting in particular the Manager's plans
for marketing and distributing shares of various series of the Trust. They noted
that a contractual breakpoint was in place for the management fee and was
intended to provide that the Fund's shareholders would share in benefits from
economies of scale as the Fund grows. The Trustees noted that the Fund's
contractual management fee had been reduced in accordance with the

                                                    www.MAINSTAYfunds.com     37


terms of the breakpoint schedule applicable to the Fund, and reviewed
information provided by the Manager intended to show that the profitability of
the Fund to the Manager and the Subadviser was not excessive. In discussing the
large size of the Fund relative to the low asset level at which the breakpoint
became applicable, the Manager emphasized the increase of the Manager's and
Subadvisor's costs applicable to the Fund as its assets have increased, the lack
of a significant increase of the Manager's and Subadvisor's profitability level
relating to the Fund, the Fund's competitive fee level, and the Manager's
willingness to keep the Fund open to new investors. Acknowledging the difficulty
of forecasting economies of scale, the Trustees generally expressed an intention
to monitor the Manager's profitability and consider the application of fee
breakpoints or other appropriate measures as the Board may determine from time
to time. The Trustees reviewed historical information about changes in the
Fund's expense and asset levels over time, as well as information about certain
Fund expenses that would remain fixed even as Fund assets increase and,
therefore, provide the Fund with benefits from economies of scale as the Fund
grows. The Trustees considered various information about transfer agency
expenses, including information showing that transfer agency fees of a
significant number of series of the Trust (although not every such series or
with respect to every share class of each series) tended to be high, when
aggregated and expressed as a percentage of the assets of certain series,
compared to the mutual fund industry average according to certain studies
reviewed by the Board and, therefore, adversely affected gross expense ratios.
The Board received information about potential effects on the Manager were it to
subsidize certain portions of the Trust's transfer agency fees. The Trustees
noted that a significant number of shareholders of the Trust's series had small
amounts invested in the series, and have considered measures intended to
increase average shareholder account size and/or otherwise reduce the Trust's
transfer agency fees and expenses, including steps that the Manager has taken to
encourage shareholders to consolidate or close small accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts, that had investment objectives similar to
that of the Fund. The Trustees took into account information provided by the
Manager or Subadvisor about the relative scope of services provided to the Fund
and to those accounts or explanations about the accounts' histories. In
considering the extent of the fees received by the Manager and Subadvisor for
providing services to the Fund, the Trustees evaluated factors such as the fees
and expenses borne by other registered funds in the market pursuing strategies
generally similar to those followed by the Fund. The Trustees considered the
Fund's historical and proposed contractual and net management fees, its
anticipated expense ratio, and various components of that expense ratio, in
comparison to other funds in comparison groupings prepared by outside data
providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.
At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/S/ CHRISTOPHER O. BLUNT


Christopher O. Blunt
President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee, and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Class R1 shares are sold with
no initial sales charge or CDSC, and have no annual 12b-1 fee. Class R2 shares
are sold with no initial sales charge or CDSC, and have an annual 12b-1 fee of
..25%. Class R1 and R2 shares are available only through corporate-sponsored
retirement programs, which include certain minimum program requirements.
Performance figures reflect certain fee waivers and/or expense limitations,
without which total returns may have been lower. The fee waivers and/or expense
limitations are contractual and may be modified or terminated only with the
approval of the Board of Trustees. From inception (9/13/94) through 12/31/94
(for Class A, first offered 1/3/95), 8/31/98 (for Class C, first offered
9/1/98), and 12/31/03 (for Class I, R1, and R2, first offered 1/2/04),
performance of Class A, C, I, R1, and R2 shares includes the historical
performance of Class B shares adjusted to reflect the applicable sales charge
(or CDSC) and fees and expenses for Class A, C, I, R1, and R2 shares.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY INTERNATIONAL EQUITY FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Rupal J. Bhansali of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund seeks to generate superior risk-adjusted returns by investing in
quality companies that we believe are currently undervalued. The Fund normally
invests at least 80% of its assets in equity securities of issuers, wherever
organized, who do business mainly outside the United States. Investments will be
made in a variety of countries with established economies, as well as
emerging-market countries that we believe present favorable opportunities. In
implementing this strategy, we utilize a bottom-up stock-picking investment
discipline. Proprietary quantitative and qualitative tools are used to identify
attractive companies. In-depth, original fundamental research is performed on
identified companies to assess their business and investment prospects.
Particular attention is paid to cash flow, return on invested capital, and
management's demonstrated ability to create shareholder value. Portfolios are
constructed by combining securities with low correlation. Quantitative tools are
used for risk control at the portfolio level. Country allocations in the
portfolio are a result of the bottom-up stock-selection process. To reduce risk,
an attempt is made at the portfolio level to stay within a reasonable range of
the key constituents of the MSCI EAFE(R) Index,(1) unless the stock-selection
process strongly argues against it.

WHAT MAJOR FACTORS INFLUENCED INTERNATIONAL EQUITIES DURING THE 12 MONTHS ENDED
OCTOBER 31, 2005?

International equity markets advanced significantly during the 12-month
reporting period. The global focus on high energy prices sparked renewed
concerns about higher inflation. In Japan, good corporate sector performance has
begun to spill into the household sector, creating a recovery path that will
likely be led by private demand. From a price per-spective, the Japanese economy
was still in a mild deflationary period. Still, the possible economic
ramifications of oil price fluctuations on Japan's domestic and overseas
businesses could not be ignored.

In Europe, economic news was mixed. The euro hit a record high versus the U.S.
dollar in November 2004 and has since declined in value. The European Central
Bank has expressed concern about the weakness but has not yet been moved to
raise interest rates. In the United States, corporate profit growth and higher
commodity prices once again ignited inflation fears, but the Federal Open Market
Committee continued to raise the targeted federal funds rate at a measured pace,
with eight 25-basis-point increases during the reporting period. (A basis point
is one-hundredth of a percentage point.) At the end of October 2005, the federal
funds target rate stood at 3.75%, and the market anticipated additional
tightening moves.

The key factor driving international markets, however, was not interest rates
but an appetite for risk. The more-volatile parts of the global economy
continued to outperform during the reporting period. With gross domestic product
showing strength worldwide, emerging markets, commodity-related stocks, and
high-fixed-cost companies continued to enjoy market favor.

WHAT WERE THE STRONGEST AND WEAKEST AREAS OF THE MARKET DURING THE REPORTING
PERIOD?

The international equity market saw broad-based advances during the 12-month
period ended October 31, 2005, with every sector recording gains. Within the
MSCI EAFE(R) Index, the materials and energy sectors were the best performers in
U.S. dollar terms. Telecommunications services and information technology were
the worst-performing sectors, although they still generated positive returns in
U.S. dollars during the reporting period.

WHICH FUND HOLDINGS DID PARTICULARLY WELL DURING THE REPORTING PERIOD?

Deutsche Boerse, a German-based provider of various stock-exchange services, was
one of the strongest positive contributors to the Fund's performance during the
reporting period. The company approved a significant share-buyback program
during the reporting period and did not rule out a dividend payout ratio
increase. Ryanair Holdings, an Ireland-based low-cost airline that operates
through Europe, was another strong performer. The company continued to increase
business and profits while other airlines were struggling with the high cost of
fuel. At a time when high fuel prices were forcing many competitors out of
business, Ryanair actually flew more passengers than British Airways. Another
positive contributor was Nestle, the Switzerland-based


Foreign securities may be subject to greater risks than U.S. investments,
including currency fluctuations, less-liquid trading markets, greater price
volatility, political and economic instability, less publicly available
information, and changes in tax or currency laws or monetary policy. These risks
are likely to be greater in emerging markets than in developed markets. The Fund
may invest in derivatives, which may increase the volatility of the Fund's net
asset value and may result in a loss to the Fund. The Fund may experience a

 8   MainStay International Equity Fund


food manufacturer, whose businesses include coffee, infant formula, bottled
water, and pet food. Of particular note was Nestle's lucrative bottled-water
business, because bottled water has become a powerhouse in the global beverage
market.

WHAT STOCKS DETRACTED FROM RESULTS?

Enel, the largest Italian electric utility, detracted from the Fund's
performance during the reporting period. The company's cash position was
affected by a change in the Italian government's rules on amortization of
property, plant, and equipment. Another stock that hurt performance was
Kingfisher, a do-it-yourself retailer that faced profit problems in a
deteriorating U.K. retail environment. Tesco, a U.K. retailing giant, declined
when the market responded negatively to the actions of Asda, a competitor owned
by Wal-Mart Stores.

WERE THERE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD?

We added Roche Holdings, a Switzerland-based pharmaceutical company, to the
Fund's portfolio during the reporting period because of the company's strong
growth prospects, which were strengthened by increased penetration in the
oncology field. Roche also has a solid pipeline of products that many analysts
appear to have ignored in their forecasts. We also initiated a Fund position in
Denso, an auto parts manufacturer based in Japan. Although we have concerns
about projected auto sales, we feel that as the main supplier to Toyota, Denso
may benefit. Toyota is one of the few automakers that has gained market share
globally. We also added to several of the Fund's energy positions, including BP
and Total, because earnings expectations have not kept up with the rising price
of oil.

We eliminated the Fund's position in Euronext, a pan-European stock exchange
that resulted from the merger of exchanges in Paris, Brussels, Amsterdam, and
Lisbon. The decision to sell Euronext was driven by concerns that the winds of
consolidation would lead the company to overpay for the acquisition of the
London Stock Exchange. For this reason, we felt it prudent to liquidate the
Fund's position. The Fund took profits in Porsche, an automaker known for its
premium sports cars and new Cayenne SUV. We decided to sell the stock after we
learned that the company's management had decided to acquire a 20% stake in
Volkswagen. We believed that Volkswagen's business model was not up to par and
that shareholders would have been better served if the money had been returned
to them or invested in Porsche's own high-return business.

HOW WAS THE FUND POSITIONED RELATIVE TO THE MSCI EAFE(R) INDEX AS OF OCTOBER 31,
2005?

The Fund and its benchmark were invested primarily in stocks of developed
markets. The Fund tends to have limited exposure to emerging markets. As always,
we remained focused on the fundamental analysis of individual businesses rather
than on the market's perception. At the end of October 2005, the Fund was
overweighted in diversified financials and higher-dividend-yielding sectors,
such as consumer staples and utilities. The Fund was also slightly overweighted
in health care. At the same time, the Fund was underweighted in
telecommunications services, industrials, and materials. The Fund held a
market-weighted position in information technology.

During the reporting period, the Fund's holdings in diversified financials and
health care provided the biggest contribution to absolute performance. The
Fund's utility holdings detracted from absolute performance.

WHERE HAVE YOU RECENTLY FOUND THE MOST COMPELLING OPPORTUNITIES?

We have found promising opportunities in Europe and Asian nations outside Japan.
Since we find Japanese companies less compelling, the Fund has been
underweighted relative to the Index in Japan.

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
International Equity Fund (the "Fund"), a diversified fund.

The Fund currently offers six classes of shares, Class A shares, Class B shares,
Class C shares, Class I shares, Class R1 shares and Class R2 shares. Class A
shares, whose distribution commenced on January 3, 1995, are offered at net
asset value per share plus an initial sales charge. No sales charge applies on
investments of $1 million or more (and certain other qualified purchases) in
Class A shares, but a contingent deferred sales charge is imposed on certain
redemptions of such shares within one year of the date of purchase. Class B
shares and Class C shares are offered without an initial sales charge, although
a declining contingent deferred sales charge may be imposed on redemptions made
within six years of purchase of Class B shares and within one year of purchase
of Class C shares. Class I, Class R1 and Class R2 shares are not subject to a
sales charge. Distribution of Class B shares and Class C shares commenced on
September 13, 1994 and September 1, 1998, respectively. Distribution of Class I
shares, Class R1 shares and Class R2 shares commenced on January 2, 2004. The
six classes of shares bear the same voting (except for issues that relate solely
to one class), dividend, liquidation and other rights and conditions except that
Class B shares and Class C shares are subject to higher distribution fee rates
than Class A shares and Class R2 shares under a distribution plan pursuant to
Rule 12b-1 under the 1940 Act. Class I shares and Class R1 shares are not
subject to a distribution or service fee. Class R1 and Class R2 shares are
authorized to pay to New York Life Investment Management LLC, its affiliates, or
independent third-party service providers, as compensation for services rendered
to shareholders of Class R1 or Class R2 shares, a shareholder service fee.

The Fund's investment objective is to provide long-term growth of capital
commensurate with an acceptable level of risk by investing in a portfolio
consisting primarily of non-U.S. equity securities. Current income is a
secondary objective.

The Fund invests in foreign securities which carry certain risks that are in
addition to the usual risks inherent in domestic instruments. These risks
include those resulting from currency fluctuations, future adverse political and
economic developments and possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. These risks are likely to be
greater in emerging markets than in developed markets. The ability of issuers of
debt securities held by the Fund to meet their obligations may be affected by
economic and political developments in a specific country, industry or region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on the valuation date; such securities not
traded on the valuation date are valued at the mean of the latest quoted bid and
asked prices. Prices normally are taken from the principal market in which each
security trades. Temporary cash investments acquired over 60 days to maturity
are valued using the latest bid prices or using valuations based on a matrix
system (which considers such factors as security prices, yields, maturities, and
ratings), both as furnished by independent pricing services. Other temporary
cash investments are valued at amortized cost, which approximates market value.
Securities for which market quotations are not readily available are valued by
methods deemed in good faith by Board of Trustees to represent fair value.
Reasons for which securities may be valued in this manner include, but are not
limited to, trading for a security has been halted or suspended, a security has
been de-listed from a national exchange, or trading on a security's principal
market is temporarily closed at a time when under normal conditions it would be
open. The Fund did not hold securities at October 31, 2005, that were valued in
such a manner. Foreign currency forward contracts are valued at their fair
market values determined on the basis of the mean between the last current bid
and asked prices based on dealer or exchange quotations.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor conclude that such events may have effected the accuracy
of the last price reported on the local foreign market, the Manager or
Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of
the local price to reflect the impact on the price of such securities as a
result of such events.

(B) FOREIGN CURRENCY FORWARD CONTRACTS.  A foreign currency forward contract is
an agreement to buy or

 20   MainStay International Equity Fund


sell currencies of different countries on a specified future date at a specified
rate. During the period the forward contract is open, changes in the value of
the contract are recognized as unrealized gains or losses by "marking to market"
such contract on a daily basis to reflect the market value of the contract at
the end of each day's trading. When the forward contract is closed, the Fund
records a realized gain or loss equal to the difference between the proceeds
from (or cost of) the closing transaction and the Fund's basis in the contract.
The Fund enters into foreign currency forward contracts primarily to hedge its
foreign currency denominated investments and receivables and payables against
adverse movements in future foreign exchange rates or to try to enhance the
Fund's returns.

The use of foreign currency forward contracts involves, to varying degrees,
elements of market risk in excess of the amount recognized in the Statement of
Assets and Liabilities. The contract amount reflects the extent of the Fund's
involvement in these financial instruments. Risks arise from the possible
movements in the foreign exchange rates underlying these instruments. The
unrealized appreciation on forward contracts reflects the Fund's exposure at
period end to credit loss in the event of a counterparty's failure to perform
its obligations. (see Note 7).

(C) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (see Note 7).

(D) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are withheld at the source.

(E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
quarterly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

The following table discloses the current year reclassifications between
undistributed net investment income, accumulated net realized gain on
investments, and paid-in capital.

<Table>
<Caption>
                            ACCUMULATED NET
 UNDISTRIBUTED             REALIZED GAIN ON  PAID-IN-
 NET INVESTMENT INCOME          INVESTMENTS   CAPITAL
                                       
            $(932,655)             $931,504    $1,151
 ----------------------------------------------------
</Table>

The reclassification for the Fund is primarily due to foreign currency gain
(loss).

(F) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.

Discounts and premiums on short-term securities are accreted and amortized,
respectively, on the straight line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(G) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at
the mean between the buying and selling rates last quoted by any major U.S. bank
at the following dates:

(i)  market value of investment securities, other assets and liabilities--at the
     valuation date,

(ii) purchases and sales of investment securities, income and expenses--at the
     date of such transactions.

The assets and liabilities are presented at the exchange rates and market values
at the close of the period. The realized and unrealized changes in net assets
arising from fluctuations in exchange rates and market prices of securities are
not separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and

                                                    www.MAINSTAYfunds.com     21

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

withholding taxes as recorded on the Fund's books, and the U.S. dollar
equivalent amount actually received or paid. Net currency gains or losses from
valuing such foreign currency denominated assets and liabilities, other than
investments, are reflected in unrealized foreign exchange gains or losses at
period end exchange rates.

(H) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(I) REDEMPTION FEE.  The Fund imposes a 2.00% redemption fee on redemptions
(including exchanges) of Fund shares made within 60 days of their date of
purchase for Class A, Class B, Class C and Class I shares. The redemption fee is
designed to offset brokerage commissions and other costs associated with
short-term trading and is not assessed on the shares acquired through the
reinvestment of dividends or distributions paid by the Fund. The redemption fees
are included in the Statement of Changes in Net Assets' shares redeemed amount
and retained by the Fund.

(J) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(K) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and facilities furnished at an annual percentage of the Fund's average
daily net assets as follows: 0.90% on assets up to $500 million and 0.85% on
assets in excess of $500 million. Effective August 1, 2005, the Manager has
entered into a written expense limitation agreement, under which the Manager has
agreed to reimburse the expenses of the Fund so that the total operating
expenses (excluding taxes, interest, litigation, extraordinary expenses, and
brokerage and other transaction expenses relating to the purchase or sale of
portfolio investments) do not exceed, on an annualized basis, 1.75% of the
average daily net assets of the Class A shares. An equivalent reimbursement, in
an equal amount of basis points, will be applied to the other share classes. The
Manager, within three years of incurring such expenses, may recoup the amount of
any management fee waiver or expense reimbursement from the Fund pursuant to
this agreement if such recoupment does not cause the Fund to exceed the expense
limitations. At October 31, 2005, the Fund had $33,294 of recoupment available.
This amount is available until October 31, 2008. This expense limitation may be
modified or terminated only with the approval of the Board of Trustees. Prior to
August 1, 2005 and after December 1, 2004, NYLIM agreed to voluntarily reimburse
the expenses of the Fund so that the total operating expenses would not exceed
on an annualized basis 1.95% of the average daily net assets of the Class A
shares, and such that there would be an equivalent reduction for the other
classes of shares. For the year ended October 31, 2005, the Manager earned fees
from the Fund in the amount of $2,301,353 and waived its fee and/or reimbursed
expenses in the amount of $39,296.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager pays the Subadvisor a monthly fee of 0.60% of the Fund's
average daily net assets of the Fund. To the extent the Manager has agreed to
reimburse expenses of the Fund, the Subadvisor has voluntarily agreed to do so
proportionately.

(B) DISTRIBUTION, SERVICE AND SHAREHOLDER SERVICE FEES.  The Trust, on behalf of
the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund,
with respect to Class A, Class B, Class C, and Class R2

 22   MainStay International Equity Fund


shares, has adopted distribution plans (the "Plans") in accordance with the
provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A and Class
R2 Plan, the Distributor receives a monthly fee from the Fund at an annual rate
of 0.25% of the average daily net assets of the Fund's Class A and Class R2
shares, which is an expense of the Class A and Class R2 shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The Plans provide that the Class B and Class C shares of the Fund also
incur a service fee at the annual rate of 0.25% of the average daily net asset
value of the Class B or Class C shares of the Fund. Class I shares are not
subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

The Fund has adopted a shareholder services plan with respect to Class R1 and
Class R2 shares. Under the terms of this plan, Class R1 and Class R2 shares are
authorized to pay to NYLIM, its affiliates, or independent third-party
providers, as compensation for services rendered, a shareholder services fee at
the rate of 0.10% of the average daily net assets of the Fund's Class R1 and R2
shares.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $462,015 for the year
ended October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $5,705, $63,443 and $1,830, respectively, for the year ended October
31, 2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund for the year ended
October 31, 2005, amounted to $820,548.
(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus the Fund only pays a
portion of the fees identified above.

(F) CAPITAL.  At October 31, 2005, New York Life held shares of Class A with a
net value of $11,218,391. This represents 12.6% of Class A shares net assets and
3.4% of the Funds total net assets at period end.

(G) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$7,051 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $52,237 for the year ended
October 31, 2005.

NOTE 4--CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, The Bank of New York acted as custodian for the Fund.

NOTE 10--OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those arrangements and certain other levels of trading
by fund shareholders over the period from 1999 to 2003 may have had on the
funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.9 million to nine MainStay funds. The amount paid to the MainStay
International Equity Fund was $772,000. NYLIM has also agreed to reimburse or
pay all expenses relating to the Board of Trustees' review of this matter and
has paid substantially all of the costs associated with the other regulatory
matters described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay International Equity Fund ("the
Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2005, and the related statement of operations for the year then ended, and the
statements of changes in net assets and financial highlights for each of the
years in the two-year period then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The financial highlights for the
periods presented through October 31, 2003, were audited by other auditors,
whose report dated December 18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay International Equity Fund of The MainStay Funds as of October 31, 2005,
the results of its operations for the year then ended, and the changes in its
net assets and financial highlights for each of the years in the two-year period
then ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreement, the Board of Trustees requested and received from the
Manager and Subadvisor, and reviewed, a wide variety of information. The
Trustees also requested and received information from outside data providers and
information and analysis from a third party consultant. The Trustees considered
various industry and regulatory trends in their deliberations. In considering
approval of these Agreements, and in evaluating the fairness of the compensation
to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and Subadvisor have provided historically to the Fund, and also
generally to other series of the Trust. The Manager's services to the Trust have
included investment management services, including the selection and supervision
of portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the
day-to-day management of the portfolio, providing reports to the Manager, and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. In considering the Manager's
and Subadvisor's practices relating to best execution of portfolio trades, the
Board reviewed reports of the Fund's Brokerage Committee including with respect
to analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager, the Subadvisor and certain other service
providers, as well as the Subadvisor's attention to its compliance program. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager and Subadvisor were such that, in the context of the Board's overall
review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's top quartile performance over
longer time periods when compared with funds concluded by Trustees to be peers
of the Fund and its shorter term mid-range performance compared with those
funds.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees noted the Manager's
agreement to limit the Fund's net expenses to a certain level with respect to
the Fund, with the expectation that the Manager intended, over time, to
implement measures designed to reduce the Trust's transfer agency fees. The
Trustees considered certain benefits expected for, and risks borne by, the
Manager and its affiliates, including benefits from soft dollar arrangements.
The Trustees considered the services provided to the Fund by affiliates of the
Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the
benefits to the Manager and its affiliates from those relationships. The
information provided to the Trustees indicated that the profitability to the
Manager and its affiliates arising directly from those other agreements was not
excessive. The Trustees acknowledged certain benefits to the reputation of the
Manager and its affiliates, as well to that of the Trust, from their association
with each other.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund grows, or as the Trust grows overall,
noting in particular the Manager's plans for marketing and distributing shares
of various series of the Trust. They noted the

 30   MainStay International Equity Fund


Manager's willingness to implement contractual breakpoints, and that the
contractual breakpoints in place for the management fee were intended to provide
that the Fund's shareholders would share in benefits from economies of scale
arising from the growth of Fund assets. The Trustees acknowledged that the Fund
had not yet reached the asset level at which breakpoints would reduce the
contractual management fee to which the Fund is subject. Acknowledging the
difficulty of forecasting economies of scale, the Trustees generally expressed
an intention to monitor the Manager's profitability and consider the application
of fee breakpoints or other appropriate measures as the Board may determine from
time to time. The Trustees reviewed historical information about changes in the
Fund's expense and asset levels over time, as well as information about certain
Fund expenses that would remain fixed even as Fund assets increase and,
therefore, provide the Fund with benefits from economies of scale as the Fund
grows. The Trustees noted that, to the extent the Fund's gross expenses
currently are higher than its net expenses, economies of scale achieved through
an increase in the Fund's assets might not directly benefit the Fund through
lower net expenses. The Trustees considered various information about transfer
agency expenses, including information showing that transfer agency fees of a
significant number of series of the Trust (although not every such series or
with respect to every share class of each series) tended to be high, when
aggregated and expressed as a percentage of the assets of certain series,
compared to the mutual fund industry average according to certain studies
reviewed by the Board and, therefore, adversely affected gross expense ratios.
The Board received information about potential effects on the Manager were it to
subsidize certain portions of the Trust's transfer agency fees. The Trustees
noted that a significant number of shareholders of the Trust's series had small
amounts invested in the series, and have considered measures intended to
increase average shareholder account size and/or otherwise reduce the Trust's
transfer agency fees and expenses, including steps that the Manager has taken to
encourage shareholders to consolidate or close small accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts, that had investment objectives similar to
that of the Fund. The Trustees took into account information provided by the
Manager or Subadvisor about the relative scope of services provided to the Fund
and to those accounts or explanations about the accounts' histories. In
considering the extent of the fees received by the Manager and Subadvisor for
providing services to the Fund, the Trustees evaluated factors such as the fees
and expenses borne by other registered funds in the market pursuing strategies
generally similar to those followed by the Fund. The Trustees considered the
Fund's historical and proposed contractual and net management fees, its
anticipated gross and net expense ratios, and various components of that expense
ratio, in comparison to other funds in comparison groupings prepared by outside
data providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

 2   MainStay Mid Cap Growth Fund


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.
At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/s/ Christopher O. Blunt


Christopher O. Blunt
President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Performance figures reflect certain fee waivers and/or expense limitations,
without which total returns may have been lower. The fee waivers and/or expense
limitations are contractual and may be modified or terminated only with the
approval of the Board of Trustees. Class I shares are sold with no initial sales
charge or CDSC, have no annual 12b-1 fee, and are generally available to
corporate and institutional investors with a minimum initial investment of $5
million. From inception through 3/28/05 performance of Class I shares (first
offered 3/29/05) includes the historical performance of Class A shares adjusted
to reflect the applicable sales charge (or CDSC) and fees and expenses for Class
I shares.

1. The Russell Midcap(R) Growth Index is an unmanaged index that measures the
   performance of those Russell Midcap(R) companies with higher price-to-book
   ratios and higher forecasted growth values. The Russell Midcap(R) Index is an
   un-managed 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 companies based on total market
   cap-italization. Results assume reinvestment of all income and capital gains.
   The Russell Midcap(R) Growth Index is considered to be the Fund's broad-based
   securities-market index for comparison purposes. An investment cannot be made
   directly into an index.
2. The Russell 2500(TM) Growth Index is an unmanaged index that measures the
   performance of those Russell 2500(TM) companies with higher price-to-book

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY MID CAP GROWTH FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Rudolph C. Carryl and Edmund C. Spelman
of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 80% of its assets in companies with market
capitalizations that, at the time of investment, are similar to the market
capitalizations of companies in the Russell Midcap(R) Growth Index(1) and
invests primarily in U.S. common stocks and securities related to U.S. common
stocks. The Fund seeks to participate primarily in the expanding markets of
technology, health care, communications, and other dynamic high-growth
industries. We also seek stocks with above-average growth in earnings. We select
investments according to the economic environment and the attractiveness of
particular markets, as well as the financial condition and competitiveness of
individual companies. In implementing this strategy, we use a flexible approach
and may invest in various types of companies and securities. We look for
securities that we believe may be poised for a rise in price or an acceleration
in earnings growth--possibly because of special factors, such as changes in
management, products, consumer demand, or the economy. We may sell a stock if
its earnings growth rate decelerates, if it appears overvalued in relation to
its growth rate or its peer group, or if the stock no longer appears likely to
help the Fund meet its investment objective.

WHAT MAJOR FACTORS AND RISKS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS
ENDED OCTOBER 31, 2005?

Some of the most significant factors included Federal Reserve interest-rate
hikes, high energy prices, rising inflation, and an apparent slowdown in the
rate of corporate-earnings growth and economic advancement. The potential impact
of hurricanes Katrina and Rita on the overall economy also weighed heavily on
investor sentiment.

WHAT FACTORS HAD THE GREATEST IMPACT ON THE FUND'S RELATIVE PERFORMANCE?

During the reporting period, the Fund's strong performance relative to its peers
and the Russell Midcap(R) Growth Index resulted primarily from effective
individual security selection in the consumer discretionary, energy, health
care, and materials sectors. The Fund's overweighted position in the energy
sector also contributed positively to the Fund's relative results. On the other
hand, adverse stock selection in the financials sector detracted from the Fund's
performance.

WHAT DECISIONS GUIDED THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD?

The most significant positive decision we made during the reporting period was
to overweight the Fund's exposure to the consumer discretionary and energy
sectors. Our decision to maintain the Fund's underweighted position in the
information technology sector during the reporting period also proved
beneficial.

WHICH STOCKS WERE STRONG POSITIVE CONTRIBUTORS TO THE FUND'S PERFORMANCE DURING
THE REPORTING PERIOD?

Peabody Energy and Arch Coal are leading coal producers. Both companies
benefited from robust earnings growth, healthy worldwide demand for coal, and
sharply higher coal prices.

PacifiCare Health Systems and Coventry Health Care are managed-care companies
that benefited from solid enrollment trends, premium increases, and stringent
containment of medical costs. Shares of PacifiCare Health Systems also benefited
from a takeover offer at a substantial premium by UnitedHealth Group.

Chico's FAS is a specialty retailer of exclusively designed, private-label
casual and formal women's apparel. The company's sales and earnings performance
was driven by strong merchandising and marketing strategies and by management's
solid execution of the company's business plan.

KB HOME is one of the nation's leading homebuilders. During the reporting
period, the company's positive financial results were driven by market share
gains, low interest rates, and a residential housing market that remained
relatively healthy.


Mid-capitalization companies are generally less established and their stocks may
be more volatile and less liquid than the securities of larger companies. The
Fund may experience a portfolio turnover rate of over 100% and may generate
short-term capital gains, which are taxable.

 8   MainStay Mid Cap Growth Fund


WHICH STOCKS TOOK THE GREATEST TOLL ON THE FUND'S PERFORMANCE?

First Marblehead is a Boston-based provider of student-loan services. The
company saw its stock price decline sharply after Bank of America, a key client,
rejected the automatic renewal of its contract with First Marblehead for
direct-to-consumer private student loans.

Claire's Stores is a leading international costume-jewelry retailer that
suffered when the company strayed from its core women's accessory business into
catalog sales. Overall corporate results were also hurt by the company's
purchase of the Mr. Rags chain, which caters primarily to teenage boys.

MannKind is a biopharmaceutical company focused on the development and
commercialization of therapeutic products for diabetes, cancer, and inflammatory
and autoimmune diseases. The company's stock price declined on concerns about
additional spending requirements for the development of the company's inhalable
insulin product for diabetics.

Acxiom is a global information-management solutions company that suffered when
revenue growth came under pressure on several fronts. The company saw declining
volume in Europe, customer consolidations, ongoing competition from IBM, and
increasing integration of enterprise software.

Pacific Sunwear of California is a specialty retailer of private-label casual
apparel for young men and women. The company's stock declined following reports
of weaker-than-expected comparable-store sales growth.

Maverick Tube, which manufactures and markets steel tubular products for the oil
services industry, saw its share price decline on competitive concerns.
Specifically, investors worried that pricing pressure from an increase in carbon
grade tubular imports might make it difficult for Maverick Tube to meet its
revenue and earnings goals.

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD?

Yes. In the health care sector, we added Omnicare, Health Net, Health Management
Associates, Invitrogen, and WellChoice to the Fund. Omnicare provides
professional pharmacy and data management services to skilled nursing, assisted
living, and other institutional health care providers. The company's results are
being bolstered by timely acquisitions. Health Net and WellChoice are
managed-care companies that have benefited from strong enrollment and industry
pricing trends. Health Management Associates is a Naples-based hospital-
management company, which stands to benefit from favorable demographic trends in
Florida. Invitrogen is a leading provider of research products and services to
academic, government, biotechnology, and biopharmaceutical clients. The company
is enjoying double-digit bottom-line growth because of robust demand for its
products and services.

In the energy sector, we added Tesoro, Atwood Oceanics, and Massey Energy.
Tesoro is a leading refiner and marketer of petroleum products whose sales and
earnings are benefiting from strong fundamentals in the energy industry. Atwood
Oceanics is an oil and natural gas contract driller. Massey Energy is a
well-positioned coal producer.

In the consumer discretionary sector, we added American Eagle Outfitters and Las
Vegas Sands to the Fund. American Eagle is a mall-based specialty retailer of
men's and women's casual apparel, footwear, and accessories. The company has
enjoyed healthy same-store sales trends nationwide. Las Vegas Sands has
benefited from the growing popularity of Las Vegas as a vacation destination.

WHICH STOCKS DID THE FUND SELL DURING THE REPORTING PERIOD?

We sold the Fund's positions in First Marblehead, Pacific Sunwear of California,
Acxiom, Maverick Tube, and Claire's Stores, all of which detracted from the
Fund's performance. During the reporting period, we also eliminated the Fund's
position in St. Jude Medical, a provider of implantable medical devices, because
the company's shares grew beyond the Fund's capitalization parameters. We sold
the Fund's position in credit-card company First Providian after an offer from
Washington Mutual at a substantial premium caused a surge in First Providian's
share price. We sold Doral Financial and Patterson Companies because of rapidly
deteriorating business fundamentals.

HOW DID THE FUND'S WEIGHTINGS CHANGE DURING THE REPORTING PERIOD?

The Fund increased its exposure to the energy sector during the reporting
period. Over the same period, we increased the Fund's allocation to the
materials sector. During the reporting period, the Fund decreased its weightings
in the consumer discretionary, health care, and information technology sectors.

                                                     www.MAINSTAYfunds.com     9


HOW DO THE FUND'S WEIGHTINGS COMPARE WITH THOSE OF THE RUSSELL MIDCAP(R) GROWTH
INDEX?

As of October 31, 2005, the Fund was overweighted relative to the Russell
Midcap(R) Growth Index in the consumer discretionary, energy, financials, health
care, and materials sectors. At the same time, the Fund was underweighted
relative to the Index in the industrials and information technology sectors. At
the end of the reporting period, the Fund had no holdings in the consumer
staples, telecommunications services, or utilities sectors.

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 Mid Cap
Growth Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Distribution of Class A
shares, Class B shares and Class C shares commenced on January 2, 2001. Class A
shares are offered at net asset value per share plus an initial sales charge. No
sales charge applies on investments of $1 million or more (and certain other
qualified purchases) in Class A shares, but a contingent deferred sales charge
is imposed on certain redemptions of such shares within one year of the date of
purchase. Class B shares and Class C shares are offered without an initial sales
charge, although a declining contingent deferred sales charge may be imposed on
redemptions made within six years of purchase of Class B shares and within one
year of purchase of Class C shares. Distribution of Class I shares commenced on
March 29, 2005. Class I shares are not subject to sales charge. Class A shares,
Class B shares, Class C shares and Class I shares bear the same voting (except
for issues that relate solely to one class), dividend, liquidation and other
rights and conditions. Each class of shares other than Class I shares bears
distribution and/or service fee payments under a distribution plan pursuant to
Rule 12b-1 under the 1940 Act. Class I shares are not subject to a distribution
or service fee.

The Fund's investment objective is to seek long-term growth of capital.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on the valuation date; such securities not
traded on the valuation date are valued at the mean of the latest quoted bid and
asked prices. Prices are normally taken from the principal market in which each
security trades. Temporary cash investments acquired over 60 days to maturity
are valued using the latest bid prices or using valuations based on a matrix
system (which considers such factors as security prices, yields, maturities, and
ratings), both as furnished by independent pricing services. Other temporary
cash investments are valued at amortized cost, which approximates market value.
Securities for which market quotations are not readily available are valued by
methods deemed in good faith by Board of Trustees to represent fair value.
Reasons for which securities may be valued in this manner include, but are not
limited to, trading for a security has been halted or suspended, a security has
been de-listed from a national exchange, or trading on a security's principal
market is temporarily closed at a time when under normal conditions it would be
open. The Fund did not hold securities at October 31, 2005, that were valued in
such manner.

(B) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See Note 7).

(C) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are withheld at the source.

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
quarterly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

 20   MainStay Mid Cap Growth Fund


The following table discloses the current year reclassifications between net
investment loss and additional paid-in-capital arising from permanent
differences; net assets at October 31, 2005, are not affected.

<Table>
<Caption>
                                ADDITIONAL PAID-IN
        NET INVESTMENT LOSS          CAPITAL
                         
             $1,422,180            $(1,422,180)
- ---------------------------------------------------
</Table>

The reclassification for the Fund is due to the fact that net operating losses
cannot be carried forward for federal income tax purposes.

(E) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on short-term securities are accreted and amortized,
respectively, on the straight line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(G) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(H) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.75% on assets up to $500 million and
0.70% on assets in excess of $500 million. Effective August 1, 2005, the Manager
has entered into a written expense limitation agreement, under which the Manager
has agreed to reimburse the expenses of the Fund so that the total operating
expenses (excluding taxes, interest, litigation, extraordinary expenses, and
brokerage and other transaction expenses relating to the purchase or sale of
portfolio investments) do not exceed, on an annualized basis, 1.50% of the
average daily net assets of the Class A shares. An equivalent reimbursement, in
an equal amount of basis points, will be applied to the other share classes. The
Manager, within three years of incurring such expenses, may recoup the amount of
any management fee waiver or expense reimbursement from the Fund pursuant to
this agreement if such recoupment does not cause the Fund to exceed the expense
limitations. At October 31, 2005, the Fund had $64,788 of recoupment available.
This amount is available until October 31, 2008. This expense limitation may be
modified or terminated only with the approval of the Board of Trustees. Prior to
August 1, 2005, the Manager had voluntarily agreed to reimburse the expenses of
the Fund so that total operating expenses would not exceed, on an annualized
basis, 1.50%, of the average daily net assets of the Class A shares, and such
that there would be an equivalent reduction for the other classes of shares. For
the year ended October 31, 2005, the Manager earned fees from the Fund in the
amount of $828,019 and waived its fees and/or reimbursed expenses in the amount
of $144,183.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of
0.375%

                                                    www.MAINSTAYfunds.com     21

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

of the average daily net assets of the Fund. To the extent the manager has
agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed
to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from
the Fund at an annual rate of 0.25% of the average daily net assets of the
Fund's Class A shares, which is an expense of the Class A shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The Plans provide that the Class B and Class C shares of the Fund also
incur a service fee at the annual rate of 0.25% of the average daily net asset
value of the Class B or Class C shares of the Fund. Class I shares are not
subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $74,749 for the year ended
October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $5,797, $58,470 and $2,789, respectively, for the year ended October
31, 2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund, for the year ended
October 31, 2005, amounted to $442,768.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus the Fund only pays a
portion of the fees identified above.

(F) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$3,024 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $37,707 for the year ended
October 31, 2005.

NOTE 4--CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, The Bank of New York acted as custodian for the Fund.

NOTE 5--FEDERAL INCOME TAX:

As of October 31, 2005, the components of accumulated gain/(loss) on a tax basis
were as follows:

<Table>
<Caption>
     ACCUMULATED                      TOTAL
     CAPITAL AND     UNREALIZED    ACCUMULATED
     OTHER LOSSES   APPRECIATION      LOSS
                          
     $(2,604,998)   $32,870,922    $30,265,924
- ----------------------------------------------
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to wash sale loss deferrals.

At October 31, 2005, for federal income tax purposes, capital loss carryforwards
of $2,604,998 were available as shown in the table below, to the extent provided
by the regulations to offset future realized gains of the Fund

 22   MainStay Mid Cap Growth Fund


through the years indicated. To the extent that these loss carryforwards are
used to offset future capital gains, it is probable that the capital gains so
offset will not be distributed to shareholders.

The Fund utilized $7,836,185 of capital loss carryforwards during the year ended
October 31, 2005.

NOTE 6--PURCHASES AND SALES OF SECURITIES (IN 000'S):

During the year ended October 31, 2005, purchases and sales of securities, other
than short-term securities, were $65,773 and $47,319, respectively.

NOTE 7--PORTFOLIO SECURITIES LOANED:

As of October 31, 2005, the Fund had securities on loan with an aggregate market

investments in accordance with the Fund's securities lending procedures.
Pursuant to Rule 2a-7, securities purchased with collateral received are valued
at amortized cost.

NOTE 8--LINE OF CREDIT:

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

NOTE 10--OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those arrangements and certain other levels of trading
by fund shareholders over the period from 1999 to 2003 may have had on the
funds. As a result of this review in December 2005, NYLIM made payments totaling
$5.9 million to nine MainStay funds. No payment was made with respect to the
MainStay Mid Cap Growth Fund. NYLIM has also agreed to reimburse or pay all
expenses relating to the Board of Trustees' review of this matter and has paid
substantially all of the costs associated with the other regulatory matters
described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Mid Cap Growth Fund ("the Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2005, and
the related statement of operations for the year then ended, and the statements
of changes in net assets and financial highlights for each of the years in the
two-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Mid Cap Growth Fund of The MainStay Funds as of October 31, 2005, the
results of its operations for the year then ended, and the changes in its net
assets and financial highlights for each of the years in the two-year period
then ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreement, the Board of Trustees requested and received from the
Manager and Subadvisor, and reviewed, a wide variety of information. The
Trustees also requested and received information from outside data providers and
information and analysis from a third party consultant. The Trustees considered
various industry and regulatory trends in their deliberations. In considering
approval of these Agreements, and in evaluating the fairness of the compensation
to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and Subadvisor have provided historically to the Fund, and also
generally to other series of the Trust. The Manager's services to the Trust have
included investment management services, including the selection and supervision
of portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the
day-to-day management of the portfolio, providing reports to the Manager, and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. In considering the Manager's
and Subadvisor's practices relating to best execution of portfolio trades, the
Board reviewed reports of the Fund's Brokerage Committee including with respect
to analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager, the Subadvisor and certain other service
providers, as well as the Subadvisor's attention to its compliance program. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager and Subadvisor were such that, in the context of the Board's overall
review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's top decile performance over
recent time periods and its top quartile performance since inception when
compared with funds concluded by Trustees to be peers of the Fund.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees noted the Manager's
agreement to limit the Fund's net expenses to a certain level with respect to
the Fund, with the expectation that the Manager intended, over time, to
implement measures designed to reduce the Trust's transfer agency fees. The
Trustees considered certain benefits expected for, and risks borne by, the
Manager and its affiliates, including benefits from soft dollar arrangements.
The Trustees considered the services provided to the Fund by affiliates of the
Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the
benefits to the Manager and its affiliates from those relationships. The
information provided to the Trustees indicated that the profitability to the
Manager and its affiliates arising directly from those other agreements was not
excessive. The Trustees acknowledged certain benefits to the reputation of the
Manager and its affiliates, as well to that of the Trust, from their association
with each other.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund grows, or as the Trust grows overall,
noting in particular the Manager's plans for marketing and distributing shares
of various series of the Trust. They noted the Manager's willingness to
implement contractual

 28   MainStay Mid Cap Growth Fund


breakpoints, and that the contractual breakpoints in place for the management
fee were intended to provide that the Fund's shareholders would share in
benefits from economies of scale arising from the growth of Fund assets. The
Trustees acknowledged that the Fund had not yet reached the asset level at which
breakpoints would reduce the contractual management fee to which the Fund is
subject. Acknowledging the difficulty of forecasting economies of scale, the
Trustees generally expressed an intention to monitor the Manager's profitability
and consider the application of fee breakpoints or other appropriate measures as
the Board may determine from time to time. The Trustees reviewed historical
information about changes in the Fund's expense and asset levels over time, as
well as information about certain Fund expenses that would remain fixed even as
Fund assets increase and, therefore, provide the Fund with benefits from
economies of scale as the Fund grows. The Trustees noted that, to the extent the
Fund's gross expenses currently are higher than its net expenses, economies of
scale achieved through an increase in the Fund's assets might not directly
benefit the Fund through lower net expenses. The Trustees considered various
information about transfer agency expenses, including information showing that
transfer agency fees of the Fund were among the highest of The MainStay Funds,
and that transfer agency fees of a significant number of series of the Trust
(although not every such series or with respect to every share class of each
series) tended to be high, when aggregated and expressed as a percentage of the
assets of certain series, compared to the mutual fund industry average according
to certain studies reviewed by the Board and, therefore, adversely affected
gross expense ratios. The Board received information about potential effects on
the Manager were it to subsidize certain portions of the Trust's transfer agency
fees. The Trustees noted that a significant number of shareholders of the
Trust's series had small amounts invested in the series, and have considered
measures intended to increase average shareholder account size and/or otherwise
reduce the Trust's transfer agency fees and expenses, including steps that the
Manager has taken to encourage shareholders to consolidate or close small
accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts, that had investment objectives similar to
that of the Fund. The Trustees took into account information provided by the
Manager or Subadvisor about the relative scope of services provided to the Fund
and to those accounts or explanations about the accounts' histories. In
considering the extent of the fees received by the Manager and Subadvisor for
providing services to the Fund, the Trustees evaluated factors such as the fees
and expenses borne by other registered funds in the market pursuing strategies
generally similar to those followed by the Fund. The Trustees considered the
Fund's historical and proposed contractual and net management fees, its
anticipated expense ratios, and various components of that expense ratio, in
comparison to other funds in comparison groupings prepared by outside data
providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.

At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/s/ Christopher O. Blunt


Christopher O. Blunt

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

   total returns with all dividend and capital-gain distributions reinvested.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY MONEY MARKET FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1,
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Claude Athaide, Ph.D., CFA, and
Christopher Harms of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund invests in high-quality, short-term securities that are denominated in
U.S. dollars and mature in 13 months or less. The dollar-weighted average
maturity of the Fund's investment portfolio will not exceed 90 days. The Fund's
portfolio may include obligations issued or guaranteed by the U.S. government or
any of its agencies or instrumentalities. The Fund may also invest in bank and
bank holding company obligations, such as CDs and bankers' acceptances. The Fund
may own commercial paper, which consists of short-term, unsecured loans to
corporations; corporate debt securities; loans to U.S. and foreign issuers and
securities of foreign branches of U.S. and foreign banks, such as negotiable
CDs, also known as Eurodollars; time deposits; and repurchase agreements. We may
sell a security if changes in the economy, the financial situation of the
issuer, the condition and outlook of the issuer's industry, or other factors
lead us to believe that the security will not contribute to meeting the Fund's
investment objective.

WHAT WAS THE ECONOMIC AND INTEREST-RATE ENVIRONMENT DURING THE REPORTING PERIOD?

According to recent data, the U.S. economy grew at an average rate of 3.7%
during the four quarters ended September 30, 2005. Despite damage to the Gulf
Coast states from hurricanes Katrina and Rita in the late summer and early
autumn, the economy managed to grow at a seasonally adjusted annual rate of 4.3%
during the third calendar quarter of 2005, according to preliminary estimates
from the Bureau of Economic Analysis.

The Federal Open Market Committee met eight times during the 12 months ended
October 31, 2005, and raised the targeted federal funds rate 25 basis points at
each meeting. (A basis point is one-hundredth of a percentage point.) These
eight rate hikes brought the targeted federal funds rate to 3.75% at the end of
October 2005. From October 29, 2004, to October 31, 2005, three-month
Treasury-bill yields rose from 1.89% to 3.89%, while three-month LIBOR increased
from 2.17% to 4.26%.(1)

HOW DID THE FUND INVEST DURING THE REPORTING PERIOD?

The Fund performed well relative to its peers for the 12 months ended October
31, 2005. Details of the Fund's performance and appropriate disclosure can be
found on page 4 of this report.

The Fund's portfolio contained securities issued by the U.S. Treasury and
government-sponsored agencies. The Fund also held securities issued by finance,
insurance, brokerage, and industrial companies, as well as banks and bank
holding companies. These were first-tier securities, or generally those money
market instruments in the highest-rated category. As of October 31, 2005, the
average maturity of the Fund was approximately 54 days.


AN INVESTMENT IN THE FUND IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT
INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH THE FUND SEEKS TO
PRESERVE THE VALUE OF YOUR INVESTMENT AT $1.00 PER SHARE, IT IS POSSIBLE TO LOSE
MONEY BY INVESTING IN THE FUND.

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 Money
Market Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares. Class A shares, Class B
shares and Class C shares whose distributions commenced on January 3, 1995, May
1, 1986 and September 1, 1998, respectively. The shares bear the same voting
(except for issues that relate solely to one class), dividend, liquidation and
other rights and conditions.

The Fund's investment objective is to seek as high a level of current income as
is considered consistent with the preservation of capital and liquidity.

The Fund's principal investments include derivatives such as variable rate
master demand notes, "floating-rate notes" and mortgage-related and asset-backed
securities. If expectations about change in interest rates, or assessments of an
issuer's credit worthiness or market conditions are wrong, the use of
derivatives or other investments could result in a loss.

The Fund also invests in foreign securities which carry certain risks in
addition to the usual risks inherent in domestic instruments. These risks
include those resulting from future adverse political and economic developments
and possible imposition of currency exchange blockages or other foreign
governmental laws and restrictions.

The ability of issuers of debt securities held by the Fund to meet their
obligations may be affected by economic and political developments in a specific
country, industry or region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) VALUATION OF FUND SHARES.  The Fund seeks to maintain a net asset value of
$1.00 per share, although there is no assurance that it will be able to do so on
a continuous basis, and it has adopted certain investment, portfolio and
dividend and distribution policies designed to enable it to do so. An investment
in the Fund is not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.

(B) SECURITIES VALUATION.  Pursuant to Rule 2a-7 securities are valued at their
amortized cost. The amortized cost method involves valuing a security at its
cost on the date of purchase and thereafter assuming a constant amortization to
maturity of the difference between such cost and the value on maturity date.

(C) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. Dividends are declared daily and paid monthly
and capital gain distributions, if any, annually. Income dividends and capital
gain distributions are determined in accordance with federal income tax
regulations, which may differ from generally accepted accounting principles.

(E) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Interest income is
accrued daily and discounts and premiums on securities purchased for the Fund
are accreted and amortized, respectively, on the straight line method.

Investment income and realized and unrealized gains and losses on investments
are allocated to separate classes of shares based upon their relative net assets
on the date the income is earned or realized and unrealized gains and losses are
incurred.

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(G) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(H) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred.

Based on experience, management is of the view that the risk of loss in
connection with these potential indemnification obligations is remote; however,
there can be no assurance that material liabilities related to such obligations
will not arise in the future that could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.50% on assets up to $300 million, 0.45%
on assets from $300 million to $700 million, 0.40% on assets from $700 million
to $1.0 billion and 0.35% on assets in excess of $1.0 billion. Effective August
1, 2005, the Manager has entered into a written expense limitation agreement,
under which the Manager has agreed to reimburse the expenses of the Fund so that
the total operating expenses (excluding taxes, interest, litigation,
extraordinary expenses, and brokerage and other transaction expenses relating to
the purchase or sale of portfolio investments) do not exceed, on an annualized
basis, 0.70% of the average daily net assets of the Class A shares. An
equivalent reimbursement, in an equal amount of basis points, will be applied to
the other share classes. The Manager, within three years of incurring such
expenses, may recoup the amount of any management fee waiver or expense
reimbursement from the Fund pursuant to this agreement if such recoupment does
not cause the Fund to exceed the expense limitations. At October 31, 2005, the
Fund had $232,330 of recoupment available. This amount is available until
October 31, 2008. This expense limitation may be modified or terminated only
with the approval of the Board of Trustees. Prior to August 1, 2005, the Manager
had agreed to voluntarily reimburse the expenses of the Fund so that total
annual fund operating expenses do not exceed on an annualized basis 0.70% of the
average daily net assets of each class of shares of the Fund. For the year ended
October 31, 2005, the Manager earned from the Fund $2,328,595, and waived its
fees and/or reimbursed expenses in the amount of $1,379,735.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of the
Fund's average daily net assets of 0.25% on assets up to $300 million, 0.225% on
assets from $300 million to $700 million, 0.20% on assets from $700 million to
$1 billion and 0.175% on assets in excess of $1 billion. To the extent the
Manager has agreed to reimburse expenses of the Fund, the Subadvisor has
voluntarily agreed to do so proportionately.

(B) CONTINGENT DEFERRED SALES CHARGE.  Although the Fund does not assess a
contingent deferred sales charge upon redemption of Class B or Class C shares of
the Fund, the applicable contingent deferred sales charge will be assessed when
shares were redeemed from the Fund if the shareholder previously exchanged his
or her investment into the Fund from another Fund in the Trust. The Fund was
advised that NYLIFE Distributors LLC (the "Distributor"), an indirect wholly
owned subsidiary of New York Life, received from shareholders the proceeds from
contingent deferred sales charges for the year ended October 31, 2005, in the
amount of $1,340,992.

(C) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses for the year ended October 31, 2005,
amounted to $1,924,785.

(D) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus the Fund only pays a
portion of the fees identified above.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

(E) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$12,749 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $75,081 for the year ended
October 31, 2005.

NOTE 4--CUSTODIAN:
Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, State Street Bank and Trust Company acted as custodian for
the Fund.

NOTE 5--FEDERAL INCOME TAX:

At October 31, 2005, the components of accumulated gain/(loss) on a tax basis
were as follows:

At October 31, 2005, for federal income tax purposes capital loss carryforwards
of $5,053 were available as shown in the table below, to the extent provided by
the regulations to offset future realized gains through the years indicated. To
the extent that these loss carryforwards are used to offset future capital
gains, it is probable that the capital gains so offset will not be distributed
to shareholders.

NOTE 7--OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to agreements with certain registered
representatives of broker-dealers relating to the level of trading by clients of
those registered representatives in shares of certain funds of the Trust. All
such arrangements were terminated by the fourth quarter of 2003. NYLIM and the
Trustees of the Trust have reviewed the possible dilutive effects that
transactions under those arrangements and certain other levels of trading by
fund shareholders over the period from 1999 to 2003 may have had on the funds.
As a result of this review, in December 2005, NYLIM made payments totaling $5.9
million to nine MainStay funds. No payment was made with respect to the MainStay
Money Market Fund. NYLIM has also agreed to reimburse or pay all expenses
relating to the Board of Trustees' review of this matter, and has paid
substantially all of the costs associated with the other regulatory matters
described in this note.

 18   MainStay Money Market Fund


In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Money Market Fund ("the Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2005, and
the related statement of operations for the year then ended, and the statements
of changes in net assets and financial highlights for each of the years in the
two-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Money Market Fund of The MainStay Funds as of October 31, 2005, the
results of its operations for the year then ended, and the changes in its net
assets and financial highlights for each of the years in the two-year period
then ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreement, the Board of Trustees requested and received from the
Manager and Subadvisor, and reviewed, a wide variety of information. The
Trustees also requested and received information from outside data providers and
information and analysis from a third party consultant. The Trustees considered
various industry and regulatory trends in their deliberations. In considering
approval of these Agreements, and in evaluating the fairness of the compensation
to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and Subadvisor have provided historically to the Fund, and also
generally to other series of the Trust. The Manager's services to the Trust have
included investment management services, including the selection and supervision
of portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the
day-to-day management of the portfolio, providing reports to the Manager, and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. In considering the Manager's
and Subadvisor's practices relating to best execution of portfolio trades, the
Board reviewed reports of the Fund's Brokerage Committee including with respect
to analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager, the Subadvisor and certain other service
providers, as well as the Subadvisor's attention to its compliance program. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager and Subadvisor were such that, in the context of the Board's overall
review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's mid-range performance over
various periods of time relative to funds concluded by Trustees to be peers of
the Fund.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees noted the Manager's
agreement to limit the Fund's net expenses to a certain level with respect to
the Fund, with the expectation that the Manager intended, over time, to
implement measures designed to reduce the Trust's transfer agency fees, with the
expectation that the Manager intended, over time, to implement measures designed
to reduce the Trust's transfer agency fees. The Trustees considered certain
benefits expected for, and risks borne by, the Manager and its affiliates,
including benefits from soft dollar arrangements. The Trustees considered the
services provided to the Fund by affiliates of the Manager, NYLIFE Distributors
and NYLIM Service, under other agreements, and the benefits to the Manager and
its affiliates from those relationships. The information provided to the
Trustees indicated that the profitability to the Manager and its affiliates
arising directly from those other agreements was not excessive. The Trustees
acknowledged certain benefits to the reputation of the Manager and its
affiliates, as well to that of the Trust, from their association with each
other.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund grows, or as the Trust grows overall,
noting in particular the Manager's plans for marketing and distributing shares
of various series of the Trust. They noted the

 24   MainStay Money Market Fund


Manager's willingness to implement contractual breakpoints, and that the
contractual breakpoints in place for the management fee were intended to provide
that the Fund's shareholders would share in benefits from economies of scale
arising from the growth of Fund assets. The Trustees noted that the Fund's
contractual management fee had been reduced in accordance with the terms of the
breakpoint schedule applicable to the Fund. Acknowledging the difficulty of
forecasting economies of scale, the Trustees generally expressed an intention to
monitor the Manager's profitability and consider the application of fee
breakpoints or other appropriate measures as the Board may determine from time
to time. The Trustees reviewed historical information about changes in the
Fund's expense and asset levels over time, as well as information about certain
Fund expenses that would remain fixed even as Fund assets increase and,
therefore, provide the Fund with benefits from economies of scale as the Fund
grows. The Trustees noted that, to the extent the Fund's gross expenses
currently are higher than its net expenses, economies of scale achieved through
an increase in the Fund's assets might not directly benefit the Fund through
lower net expenses. The Trustees considered various information about transfer
agency expenses, including information showing that transfer agency fees of the
Fund and a significant number of series of the Trust (although not every such
series or with respect to every share class of each series) tended to be high,
when aggregated and expressed as a percentage of the assets of certain series,
compared to the mutual fund industry average according to certain studies
reviewed by the Board and, therefore, adversely affected gross expense ratios.
The Board received information about potential effects on the Manager were it to
subsidize certain portions of the Trust's transfer agency fees. The Trustees
noted that a significant number of shareholders of the Trust's series had small
amounts invested in the series, and have considered measures intended to
increase average shareholder account size and/or otherwise reduce the Trust's
transfer agency fees and expenses, including steps that the Manager has taken to
encourage shareholders to consolidate or close small accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts, that had investment objectives similar to
that of the Fund. The Trustees took into account information provided by the
Manager or Subadvisor about the relative scope of services provided to the Fund
and to those accounts or explanations about the accounts' histories. In
considering the extent of the fees received by the Manager and Subadvisor for
providing services to the Fund, the Trustees evaluated factors such as the fees
and expenses borne by other registered funds in the market pursuing strategies
generally similar to those followed by the Fund. The Trustees considered the
Fund's historical and proposed contractual and net management fees, its
anticipated gross and net expense ratios, and various components of that expense
ratio, in comparison to other funds in comparison groupings prepared by outside
data providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.

At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/s/ Christopher O. Blunt


Christopher O. Blunt
President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 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. The fee waivers and/or expense
limitations are contractual and may be modified or terminated only with the
approval of the Board of Trustees. From inception (5/1/86) through 12/31/94 (for
Class A, first offered 1/3/95) and 8/31/98 (for Class C, first offered 9/1/98),
performance of Class A and C shares includes the historical performance of Class
B shares adjusted to reflect the applicable sales charge (or CDSC) and fees and
expenses for Class A and C shares.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY TAX FREE BOND FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers John Fitzgerald and Laurie Walters of
MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests in U.S. tax-exempt securities of any maturity that
are, at the time of purchase, rated in one of the top four categories (or in
short-term tax-exempt securities rated in one of the top three categories) by
Moody's or S&P. Not more than 20% of the Fund's net assets may be invested in
unrated tax-exempt securities that we deem to be of comparable quality. The Fund
normally invests at least 80% of its net assets in municipal bonds. In
implementing this strategy, we use a combined approach to investing that
analyzes economic trends and factors pertinent to particular issuers and
securities.

WHAT ECONOMIC FORCES AFFECTED THE BOND MARKET DURING THE 12 MONTHS ENDED OCTOBER
31, 2005?

Throughout the reporting period, the bond market was torn on the question of how
higher energy costs would affect the economy as a whole. Either high energy
costs would raise inflation expectations or such costs would tend to reduce
aggregate demand. Toward the end of the reporting period, the consensus appeared
to shift toward the former opinion. In mid-September, the Federal Open Market
Committee's commentary crystallized this view. At the same time, the FOMC raised
the targeted federal funds rate to 3.75% in its eighth 25-basis-point move
during the reporting period. (A basis point is one-hundredth of a percentage
point.)

Despite widespread concern that hurricanes Katrina and Rita might derail trend
growth in the economy, the Federal Reserve saw rebuilding activity as
potentially stimulative. As a result, we anticipate additional interest-rate
hikes from the Federal Open Market Committee through the first quarter of 2006.
At the end of October, the Eurodollar futures market was evenly split,
anticipating either a 4.25% or a 4.50% targeted federal funds rate by March 31,
2006.

HOW DID THESE FACTORS AFFECT MUNICIPAL BONDS?

Inflation is the bane of the bond market, so not surprisingly, municipal yields
rose during the 12-month reporting period. Two-year municipal yields rose from
2.7% to 3.1%, five-year municipals advanced from 3.1% to 3.4%, 10-year
municipals climbed from 3.6% to 3.9%, and 30-year municipal yields rose from
4.4% to 4.6%. Federal Reserve policy directives hastened this fairly substantial
move.

As these changes imply, the municipal yield curve did not shift uniformly.
Instead, the yield curve flattened as the spread(1) between two-year and 30-
year municipal bond yields narrowed 20 basis points.

WHAT WAS THE FUND'S DURATION STRATEGY DURING THE REPORTING PERIOD?

From November 2004 through July 2005, we kept the Fund's duration shorter than
that of the Lehman Brothers(R) Municipal Bond Index.(2) Our positioning
expressed our bearish interest-rate outlook amid firm economic data and the
Federal Open Market Committee's resolve to steadily move targeted federal funds
rate higher. In August 2005, we lengthened the Fund's duration to a neutral
position relative to the benchmark as yields rose to more attractive levels.

WHAT POSITIONING DECISIONS SIGNIFICANTLY AFFECTED THE FUND'S PERFORMANCE?

An overweighted position in the housing sector helped the Fund's performance
during the reporting period as yield-starved investors gravitated toward sectors
that offered attractive yields relative to high-grade municipal bonds. The
housing-revenue-bond component of the Lehman Brothers(R) Municipal Bond Index
outperformed the Index as a whole by 91 basis points.

On the other hand, the Fund's underweighted exposure to the
tobacco-settlement-bond component of the Lehman Brothers(R) Municipal Bond Index
detracted from performance because the tobacco-settlement-bond component of the
Lehman Brothers(R) Municipal Bond Index outperformed the Index by 1,778 basis
points (or 17.78 percentage points). The Fund's tobacco-sector weighting at the
start of the reporting period was 1.0%, which we reduced to 0% in February 2005.
Two-percent of the Lehman Brothers(R) Municipal Bond Index is made up of
tobacco-sector bonds. Relative to high-grade municipals, tobacco spreads
tightened to their narrowest risk premiums in two years. We expect this trend to
reverse, since several issuers want to take advantage


Funds that invest in bonds are subject to interest rate, credit, and inflation
risk and can lose principal value when interest rates rise. A portion of income
may be subject to state and local taxes or the alternative minimum tax. The Fund
may invest in derivatives, which may increase the volatility of the Fund's net
asset value and may result in a loss to the Fund.

1. The terms "spread" and "yield spread" may refer to the difference in yield
   between a specific security or type of security and comparable U.S. Treasury
   issues. The terms may also refer to the difference in yield between two
   specific securities or types of securities at a given time.

   Municipal Bond Index.

of the narrow risk spreads and have announced plans to market new issues.

During the reporting period, several of the Fund's holdings were prerefunded in
Treasury securities. Such transactions may allow issuers to reduce overall
borrowing costs by issuing new securities at current market rates and retiring
old, higher-coupon issues.(3) These refundings helped the Fund's performance.
While many of the Fund's eligible securities have already been refunded, we have
maintained the Fund's positions in several other issues that could also be
refunded if municipal yields were to revisit the low levels seen in February or
June of 2005.

ARE STATE BUDGET DEFICITS STILL AN ISSUE FOR THE MUNICIPAL MARKET?

An improving economy has continued to strengthen state finances. According to
the Rockefeller Institute of Government, state tax revenue grew 13.3% in the
second calendar quarter of 2005 compared to the first calendar quarter--the
fastest growth since the Institute began tracking revenues in 1991. This
broad-based increase was seen across all three major sources of revenue:
personal income tax, corporate income tax, and general sales tax.

The opinions expressed are those of the portfolio managers as of the date of
this report and are subject to change. There is no guarantee that any forecasts
made will come to pass. This material does not constitute investment advice and
is not intended as an endorsement of any specific investment.

3. Advance refunding allows a bond issuer to float a second bond at a lower
   interest rate and to invest the proceeds from the sale of the second bond
   safely (usually in Treasury securities) to collateralize the first bond.
   Since advance-refunded bonds become the equivalent of fully tax-exempt U.S.
   Treasury securities and no longer represent the credit risk profile of the
   original borrower, they often increase in value--sometimes significantly.

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 Tax Free
Bond Fund (the "Fund"), a diversified fund.

The Fund currently offers three classes of shares.  Class A shares, whose
distribution commenced on January 3, 1995, are offered at net asset value per
share plus an initial sales charge. No sales charge applies on investments of $1
million or more (and certain other qualified purchases) in Class A shares, but a
contingent deferred sales charge is imposed on certain redemptions of such
shares within one year of the date of purchase. Class B shares and Class C
shares are offered without an initial sales charge, although a declining
contingent deferred sales charge may be imposed on redemptions made within six
years of purchase of Class B shares and within one year of purchase of Class C
shares. Distribution of Class B shares and Class C shares commenced on May 1,
1986 and September 1, 1998, respectively. Class A shares, Class B and Class C
shares bear the same voting (except for issues that relate solely to one class),
dividend, liquidation and other rights and conditions except that the Class B
shares and Class C shares are subject to higher distribution fee rates. Each
class of shares bears distribution and/or service fee payments under a
distribution plan pursuant to Rule 12b-1 under the 1940 Act.

The Fund's investment objective is to provide a high level of current income
free from regular federal income tax, consistent with the preservation of
capital.

The ability of issuers of debt securities held by the Fund to meet their
obligations may be affected by economic developments in a specific industry or
region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or brokers selected by the Fund's Manager, whose prices reflect
broker/dealer supplied valuations and electronic data processing techniques, if
such prices are deemed by the Fund's Manager to be representative of market
values, at the regular close of business of the New York Stock Exchange. Futures
contracts are valued at the last posted settlement price on the market where
such futures are principally traded. Temporary cash investments acquired over 60
days to maturity are valued using the latest bid prices or using valuations
based on a matrix system (which considers such factors as security prices,
yields, maturities, and ratings), both as furnished by independent pricing
services. Other temporary cash investments are valued at amortized cost, which
approximates market value. Securities for which market quotations are not
readily available are valued by methods deemed in good faith by Board of
Trustees to represent fair value. Reasons for which securities may be valued in
this manner include, but are not limited to, trading for a security has been
halted or suspended, a security has been de-listed from a national exchange, or
trading on a security's principal market is temporarily closed at a time when
under normal conditions it would be open. At October 31, 2005, the Fund did not
hold securities that were valued in such a manner.

(B) FUTURES CONTRACTS.  A futures contract is an agreement to purchase or sell a
specified quantity of an underlying instrument at a specified future date and
price, or to make or receive a cash payment based on the value of a securities
index. During the period the futures contract is open, changes in the value of
the contract are recognized as unrealized gains or losses by "marking to market"
such contract on a daily basis to reflect the market value of the contract at
the end of each day's trading. The Fund agrees to receive from or pay to the
broker an amount of cash equal to the daily fluctuation in the value of the
contract. Such receipts or payments are known as "variation margin". When the
futures contract is closed, the Fund records a realized gain or loss equal to
the difference between the proceeds from (or cost of) the closing transaction
and the Fund's basis in the contract. The Fund may enter into contracts for the
future delivery of debt securities in order to attempt to protect against the
effect of adverse changes in interest rates, to lengthen or shorten the average
maturity or duration of the Fund's portfolio or to try to enhance the Fund's
returns.

The use of futures contracts involves, to varying degrees, elements of market
risk in excess of the amount recognized in the Statement of Assets and
Liabilities. The contract or notional amounts and variation margin reflect the
extent of the Fund's involvement in open futures positions. Risks arise from the
possible imperfect correlation in movements in the price of futures contracts,
interest rates and the underlying hedged assets, and the possible inability of
counterparties to meet the terms of their contracts. However, the Fund's
activities in futures contracts are conducted through regulated exchanges which
minimize counterparty credit risks.

(C) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its portfolio securities or foreign currencies. Premiums are received
and are recorded as liabilities. The liabilities are subsequently adjusted and
unrealized appreciation or depreciation is recorded to reflect the current value
of the options written. Premiums received from writing options which expire are

 20   MainStay Tax Free Bond Fund


treated as realized gains. Premiums received from writing options which are
exercised or are cancelled in closing purchase transactions are added to the
proceeds or netted against the amount paid on the transaction to determine the
realized gain or loss. By writing a covered call option, in exchange for the
premium, the Fund foregoes the opportunity for capital appreciation above the
exercise price should the market price of the underlying security or foreign
currency increase but, as long as the obligation as a writer continues, have
retained the risk of loss should the price of the underlying security decline.
By writing a covered put option, the Fund, in exchange for the premium, accepts
the risk of decline in the market value of the underlying security or foreign
currency below the exercise price. After writing a put option, the Fund may
incur a loss equal to the difference between the exercise price of the option
and the sum of the market value of the underlying security plus the premium
received from the sale of the option. A call option may be covered by the call
writer's owning the underlying security throughout the option period. A call
option may also be covered by the call writer's maintaining liquid assets valued
at greater than the exercise price of the call written, in a segregated account
with its custodian.

The Fund may purchase call and put options on its portfolio securities. The Fund
may purchase call options to protect against an increase in the price of the
security it anticipates purchasing. The Fund may purchase put options on its
securities to protect against a decline in the value of the security or to close
out covered written put positions. The Fund may also purchase options to seek to
enhance returns. Risks may arise from an imperfect correlation between the
change in market value of the securities held by the Fund and the prices of
options relating to the securities purchased or sold by the Fund and from the
possible lack of a liquid secondary market for an option. The maximum exposure
to loss for any purchased option is limited to the premium initially paid for
the option.

(D) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable and non-taxable income to the shareholders of the
Fund within the allowable time limits. Therefore, no federal income or excise
tax provision is required.

(E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
monthly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

(F) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Interest income is
accrued as earned. Discounts and premiums on securities, other than short-term
securities, purchased for the Fund are accreted and amortized, respectively, on
the constant yield method over the life of the respective securities or, in the
case of a callable security, over the period to the first date of call.
Discounts and premiums on short-term securities are accreted and amortized,
respectively, on the straight line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(G) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(H) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(I) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.60% on assets up to $1.0 billion and
0.55% on assets in excess of $1.0 billion. NYLIM has agreed to waive its
management fee by 0.15% to 0.45% (effective August 1, 2004). Effective August 1,
2005, the Manager has entered into a written expense limitation agreement, under
which the Manager has agreed to reimburse the expenses of the Fund so that the
total operating expenses (excluding taxes, interest, litigation, extraordinary
expenses, and brokerage and other transaction expenses relating to the purchase
or sale of portfolio investments) do not exceed, on an annualized basis, 0.89%
of the average daily net assets of the Class A shares. An equivalent
reimbursement, in an equal amount of basis points, will be applied to the other
share classes. The Manager, within three years of incurring such expenses, may
recoup the amount of any management fee waiver or expense reimbursement from the
Fund pursuant to this agreement if such recoupment does not cause the Fund to
exceed the expense limitations. At October 31, 2005, the Fund had $30,280 of
recoupment available. This amount is available until October 31, 2008. This
expense limitation may be modified or terminated only with the approval of the
Board of Trustees. Prior to August 1, 2005 and after December 1, 2004, NYLIM
agreed to voluntarily reimburse the expenses of the Fund so that total annual
fund operating expenses would not exceed on an annualized basis 0.89% of the
average daily net assets of the Class A shares, and such that there would be an
equivalent reduction for the other classes of shares. For the year ended October
31, 2005, the Manager earned fees from the Fund in the amount of $1,740,637 and
waived its fee and/or reimbursed expenses in the amount of $504,934.

Pursuant to the terms of a Sub-Advisory Agreement between the NYLIM and MacKay
Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of
0.30% of the average daily net assets of the Fund. To the extent the Manager has
agreed to reimburse expenses of the Fund, the Subadvisor has voluntarily agreed
to do so proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, has adopted distribution plans (the "Plans") in accordance
with the provisions of Rule 12b-1 under the 1940 Act. Pursuant to the Class A
Plan, the Distributor receives a monthly fee from the Fund at an annual rate of
0.25% of the average daily net assets of the Fund's Class A shares, which is an
expense of the Class A shares of the Fund for distribution or service activities
as designated by the Distributor. Pursuant to the Class B and Class C Plans, the
Fund pays the Distributor a monthly fee, which is an expense of the Class B and
Class C shares of the Fund, at the annual rate of 0.25% of the average daily net
assets of the Fund's Class B and Class C shares. The Plans provide that the
Class B and Class C shares of the Fund also incur a service fee at the annual
rate of 0.25% of the average daily net asset value of the Class B or Class C
shares of the Fund.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $32,113 for the year ended
October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $423, $72,168 and $1,263, respectively, for the year ended October 31,
2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund for the year ended
October 31, 2005, amounted to $289,465.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage

 22   MainStay Tax Free Bond Fund


and Expense Committee, Operations Committee and Performance Committee each
receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus the Fund only pays a
portion of the fees identified above.

(F) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$7,443 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $55,677 for the year ended
October 31, 2005.

NOTE 4--CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, State Street Bank and Trust Company acted as custodian for
the Fund.

NOTE 5--FEDERAL INCOME TAX:

The Fund has maintained a year end of December 31 for federal income tax
purposes.

At October 31, 2005, the components of accumulated gain/(loss) on a tax basis
were as follows:

<Table>
<Caption>

 -------------------------------------------------------------------------
</Table>

The difference between book-basis and tax-basis unrealized appreciation is
primarily due to the tax treatment of futures transactions.

At October 31, 2005, for federal income tax purposes, capital loss carryforwards
of $32,045,133 were available, as shown in the table below, to the extent
provided by the regulations, to offset future realized gains through the years
indicated. To the extent that these loss carryforwards are used to offset future
capital gains, it is probable that the capital gains so offset will not be
distributed to shareholders.

NOTE 6--PURCHASES AND SALES OF SECURITIES (IN 000'S):

During the year ended October 31, 2005, purchases and sales of securities, other
than short-term securities, were $73,754 and $90,910, respectively.

NOTE 7 -- LINE OF CREDIT:

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

NOTE 8--CAPITAL SHARE TRANSACTIONS (IN 000'S):

NOTE 9--OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those arrangements and certain other levels of trading
by fund shareholders over the period from 1999 to 2003 may have had on the
funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.9 million to nine MainStay funds. The amount paid to the MainStay
Tax Free Bond Fund was $50,000. NYLIM has also agreed to reimburse or pay all
expenses relating to the Board of Trustees' review of this matter and has paid
substantially all of the costs associated with the other regulatory matters
described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance at this time as to the
outcome of these efforts.

 24   MainStay Tax Free Bond Fund


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Tax Free Bond Fund ("the Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2005, and
the related statement of operations for the year then ended, and the statements
of changes in net assets and financial highlights for each of the years in the
two-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Tax Free Bond Fund of The MainStay Funds as of October 31, 2005, the
results of its operations for the year then ended, and the changes in its net
assets and financial highlights for each of the years in the two-year period
then ended, in conformity with U.S. generally accepted accounting principles.

 28   MainStay Tax Free Bond Fund


BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreement, the Board of Trustees requested and received from the
Manager and Subadvisor, and reviewed, a wide variety of information. The
Trustees also requested and received information from outside data providers and
information and analysis from a third party consultant. The Trustees considered
various industry and regulatory trends in their deliberations. In considering
approval of these Agreements, and in evaluating the fairness of the compensation
to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and Subadvisor have provided historically to the Fund, and also
generally to other series of the Trust. The Manager's services to the Trust have
included investment management services, including the selection and supervision
of portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the
day-to-day management of the portfolio, providing reports to the Manager, and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. In considering the Manager's
and Subadvisor's practices relating to best execution of portfolio trades, the
Board reviewed reports of the Fund's Brokerage Committee including with respect
to analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager, the Subadvisor and certain other service
providers, as well as the Subadvisor's attention to its compliance program. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager and Subadvisor were such that, in the context of the Board's overall
review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's underperformance when compared
over several time periods with funds concluded by Trustees to be peers of the
Fund, and the Manager's and Subadvisor's agreement to monitor performance
closely in consultation with the Board.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees noted the Manager's
agreement to limit the Fund's net expenses to a certain level with respect to
the Fund. The Trustees considered certain benefits expected for, and risks borne
by, the Manager and its affiliates, including benefits from soft dollar
arrangements. The Trustees considered the services provided to the Fund by
affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under other
agreements, and the benefits to the Manager and its affiliates from those
relationships. The information provided to the Trustees indicated that the
profitability to the Manager and its affiliates arising directly from those
other agreements was not excessive. The Trustees acknowledged certain benefits
to the reputation of the Manager and its affiliates, as well to that of the
Trust, from their association with each other.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund grows, or as the Trust grows overall,
noting in particular the Manager's plans for marketing and distributing shares
of various series of the Trust. They noted the Manager's willingness to
implement contractual breakpoints, and that the contractual breakpoints in place
for the management fee were intended to provide that the Fund's shareholders
would share in benefits from econo-

                                                    www.MAINSTAYfunds.com     29


mies of scale arising from the growth of Fund assets. The Trustees acknowledged
that the Fund had not yet reached the asset level at which breakpoints would
reduce the contractual management fee to which the Fund is subject.
Acknowledging the difficulty of forecasting economies of scale, the Trustees
generally expressed an intention to monitor the Manager's profitability and
consider the application of fee breakpoints or other appropriate measures as the
Board may determine from time to time. The Trustees reviewed historical
information about changes in the Fund's expense and asset levels over time, as
well as information about certain Fund expenses that would remain fixed even as
Fund assets increase and, therefore, provide the Fund with benefits from
economies of scale as the Fund grows. The Trustees noted that, to the extent the
Fund's gross expenses currently are higher than its net expenses, economies of
scale achieved through an increase in the Fund's assets might not directly
benefit the Fund through lower net expenses. The Trustees considered various
information about transfer agency expenses and received information about
potential effects on the Manager were it to subsidize certain portions of the
transfer agency fees of the other series of the Trust.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts, that had investment objectives similar to
that of the Fund. The Trustees took into account information provided by the
Manager or Subadvisor about the relative scope of services provided to the Fund
and to those accounts or explanations about the accounts' histories. In
considering the extent of the fees received by the Manager and Subadvisor for
providing services to the Fund, the Trustees evaluated factors such as the fees
and expenses borne by other registered funds in the market pursuing strategies
generally similar to those followed by the Fund. The Trustees considered the
Fund's historical and proposed contractual and net management fees, its
anticipated gross and net expense ratios, and various components of that expense
ratio, in comparison to other funds in comparison groupings prepared by outside
data providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.

At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/s/ Christopher O. Blunt


Christopher O. Blunt
President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee, and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Performance figures reflect
certain fee waivers and/or expense limitations, without which total returns may
have been lower. The fee waivers and/or expense limitations are contractual and
may be modified or terminated only with the approval of the Board of Trustees.
From inception (12/19/97) through 12/31/94 (for Class A, first offered 1/3/95),
8/31/98 (for Class C, first offered 9/1/98), and 12/31/03 (for Class I, first
offered 1/2/04), performance of Class A, 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 A, C and I shares.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY TOTAL RETURN FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balance or
expenses you paid for the period. The hypothetical account values and expenses
may not be used to estimate the actual ending account balances or expenses you
paid for the six-month period shown. To do so, compare this 5% hypothetical
example with the 5% hypothetical examples that appear in the shareholder reports
of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

   (1.19% for Class A and 1.94%, for Class B and Class C, and 0.86% for Class I)
   multiplied by the average account value over the period, divided by 365,
   multiplied by 184 (to reflect the one-half year period).

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Rudolph C. Carryl, Edmund C. Spelman,
Richard A. Rosen, Gary Goodenough, and Christopher Harms of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests a minimum of 30% of its assets in U.S. equity
securities and a minimum of 30% in U.S. debt securities. In implementing this
investment strategy, about half of the equity portion of the Fund's portfolio is
invested in growth-oriented stocks and about half in stocks that the Fund
believes to be undervalued. In addition to holding investment-grade bonds, the
bond portion of the Fund's portfolio may purchase high-yield bonds and other
debt securities rated below investment grade that we believe may provide capital
appreciation in addition to income. The stock and bond portions of the Fund's
portfolio may both take a flexible approach by investing in a variety of
securities, industries, and issues.

WHAT MAJOR FACTORS AFFECTED THE STOCK MARKET DURING THE 12 MONTHS ENDED OCTOBER
31, 2005?

During the 12 months ended October 31, 2005, stocks generally advanced, with
value stocks outperforming growth stocks at all capitalization levels. Arguably
the biggest factor influencing the equity market during the reporting period was
the substantial rise in the price of crude oil, which continued an upward trend
that began in the previous year. Major hurricanes affected supply-and-demand
dynamics by damaging oil rigs and petrochemical plants. The price of gasoline
rose to more than $3 a gallon, which threatened to slow consumer spending.
Despite these setbacks, recent gross-domestic-product data suggest that the
overall economy has remained resilient. On the geopolitical front, negative
headlines about progress in Iraq also weighed heavily on investors' minds
throughout the reporting period.

WHAT MAJOR DECISIONS AFFECTED PERFORMANCE IN THE EQUITY PORTION OF THE FUND'S
PORTFOLIO?

The Fund invests in growth and value stocks. The growth-equity component of the
Fund's portfolio benefited from effective health care stock selection and from
overweighted positions in energy and consumer discretionary stocks. Energy
stocks also made positive contributions in value-equity component of the Fund's
portfolio. Value-oriented financial holdings showed strength, while
growth-oriented financial stocks were neutral. In the growth-equity component,
industrial stocks detracted from performance. And while the Fund owned no
telecommunication services growth stocks, the equity portion of the Fund's
portfolio did well with its value holdings in the sector.

WHICH INDIVIDUAL STOCKS PROVIDED STRONG PERFORMANCE DURING THE REPORTING PERIOD?

Among the Fund's growth equities, strong performers included coal provider
Peabody Energy, which rose on strong demand; Apple Computer, which advanced on
the popularity of the iPod; pharmacy benefit manager Caremark Rx, which
generated higher earnings; UnitedHealth Group, which saw strong demand and
pricing power in the health services sector; and biotechnology company
Genentech, which advanced on strong earnings and a dynamic new product pipeline.

Among the Fund's value stocks, energy-related holdings Transocean, Pride
International, ENSCO International, and Rowan all advanced on higher energy
prices and strong demand. We trimmed several of these positions as the stocks
approached our price targets. Among value-oriented financial stocks, operating
improvements at Prudential Financial led to excellent returns, and the Fund saw
strong results from Hartford Financial Securities Group, St. Paul Travelers, and
AFLAC. During the reporting period Motorola, Texas Instruments, Kroger, and
Cadbury Schweppes were among the Fund's other strong value holdings.

WHICH STOCKS DETRACTED FROM THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD?

In the Fund's growth-equity component, Maxim Integrated Products, an
integrated-circuit manufacturer, declined on heightened competition and a shift
in the company's product focus. Internet-auction giant eBay fell on slowing
growth in European markets and softening volume in the United States. Shares of
Brunswick, known for its boats, marine engines, and equipment for fitness,
billiards, and bowling, fell when the company lowered earnings estimates. Harman
International Industries, whose audio product sales are tied to automotive
markets, provided disappointing earnings guidance and faced competitive
challenges. Motorcycle manufacturer Harley-Davidson lowered production guidance
for the first time in the company's history. Sales, earnings, and profit
projections were also adjusted, which took a toll on the company's shares.


High-yield securities ("junk bonds") are generally considered speculative
because they present a greater risk of loss than higher-quality debt securities
and may be subject to greater price volatility. The Fund may invest in
derivatives, which may increase the volatility of the Fund's net asset value and
may result in a loss to the Fund.

 8   MainStay Total Return Fund


Among the Fund's value stocks, The Gap's shares declined when the fall season
got off to a slower-than-expected start. Pharmaceutical giant Pfizer suffered
from pending generic-drug litigation and weaker-than-expected guidance for 2006.
Nevertheless, we like the stock and have hedged nearly all of the Fund's
position using protective put contracts to limit downside exposure. Aluminum
manufacturer Alcoa faced contracting margins, and glass manufacturer
Owens-Illinois was hurt by higher costs. We sold the Fund's entire positions in
these stocks. Verizon Communications faced stronger competition but continued to
provide a high dividend yield. We used the stock's lower valuation to add to the
Fund's position late in the reporting period.

WERE THERE ANY OTHER SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING PERIOD?

In the spring of 2005, we sold the Fund's entire positions in several
growth-oriented technology stocks, including Applied Materials, KLA Tencor,
Cisco Systems, and Hewlett-Packard, and we redeployed the proceeds in other
information technology names, including Corning, EMC, Apple Computer, Intel, and
Texas Instruments.

In the value-equity component, we purchased Molson Coors Brewing but later sold
the position when the company was unable to overcome merger-integration
difficulties and the price continued to decline. Although we bought shares of
printer manufacturer Lexmark at a price that we felt was low, operating problems
and inventory issues led us to sell the Fund's position at a loss in late
October.

WHAT ECONOMIC FORCES AFFECTED THE BOND MARKET DURING THE REPORTING PERIOD?

Debate over the lasting effects of higher energy costs continued, with aggregate
demand and inflation among the key concerns. Noting that "higher energy and
other costs have the potential to add to inflation pressures," the Federal Open
Market Committee raised the targeted federal funds rate to 3.75% on September
20, 2005. The move was the FOMC's eighth 25-basis-point increase during the
12-month reporting period. (A basis point is one-hundredth of a percentage
point.)

HOW DID THE TREASURY YIELD CURVE CHANGE DURING THE REPORTING PERIOD?

From October 29, 2004, to October 31, 2005, the two-year Treasury yield advanced
from 2.56% to 4.38%. Over the same period, five-year Treasury yields increased
from 3.29% to 4.45% and 10-year Treasury yields rose from 4.03% to 4.56%. On the
other hand, 30-year Treasury yields, declined from 4.79% to 4.75%.(1) Strong
inflows from Asian central banks helped support prices among longer-dated
Treasurys and resulted in a substantial flattening of the yield curve during the
reporting period. We have positioned the bond portion of the Fund to take
advantage of this flattening trend.

WHAT ELSE DID YOU DO TO POSITION THE BOND PORTION OF THE FUND IN THIS
ENVIRONMENT?

During the 12-month reporting period, the bond portion of the Fund sought to
benefit from the yield advantages of positions in moderate- and lower-quality
securities. Specifically, we sought exposure to issuers in oil-rich emerging
economies. We also used rigorous credit analysis to help reduce the chances that
the bond portion of the Fund's portfolio would fall prey to negative credit
events.

We positioned the bond portion of the Fund's portfolio quite differently than we
did a year ago, when we were seeking credit risk to increase incremental
returns. The new positioning sought a better balance between interest-rate risk
and credit risk, particularly since compensation for taking on additional credit
risk remained modest.

HOW HAS THE MAKEUP OF THE BOND PORTION OF THE FUND'S PORTFOLIO CHANGED DURING
THE REPORTING PERIOD?

During the reporting period, the bond portion of the Fund reduced its allocation
to investment-grade and high-yield corporate bonds to acknowledge their
relatively low yields. The proceeds were split among Treasurys, agency
debentures, mortgage-backed securities, and cash equivalents.

HOW WAS THE BOND PORTION OF THE FUND INVESTED AT THE END OF THE REPORTING
PERIOD?

As of October 31, 2005, we positioned the bond portion of the Fund's portfolio
with a larger-than-usual cash position. The cash was needed to balance the
Fund's longer-duration securities, which reflected our yield-curve flattening
bias. In addition, the duration of the bond portion of the Fund's portfolio was
close to--but slightly shorter than--the duration of the Lehman Brothers(R)
Aggregate Bond Index. With a shorter duration, the Fund should be less sensitive
than the Index to changes in interest rates. (The Lehman Brothers(R) Aggregate
Bond Index is the bond component of the Fund's custom benchmark.)

At the end of October, the bond portion of the Fund's portfolio was overweighted
relative to the Lehman Brothers Aggregate Bond Index in high-yield corporate
bonds, asset-backed securities, mortgage-backed securities, and cash
equivalents. The bond portion of the Fund was underweighted relative to the
Index in Treasurys, investment-grade corporate bonds, and agency debentures.

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 Total
Return Fund (the "Fund"), a diversified fund.

The Fund currently offers four classes of shares. Class A shares, whose
distribution commenced on January 3, 1995, are offered at net asset value per
share plus an initial sales charge. No sales charge applies on investments of $1
million or more (and certain other qualified purchases) in Class A shares, but a
contingent deferred sales charge is imposed on certain redemptions of such
shares within one year of the date of purchase. Class B shares and Class C
shares are offered without an initial sales charge, although a declining
contingent deferred sales charge may be imposed on redemptions made within six
years of purchase of Class B shares and within one year of purchase of Class C
shares. Distribution of Class B shares and Class C shares commenced on December
29, 1987 and September 1, 1998, respectively. Class I shares are not subject to
a sales charge. Distribution of Class I shares commenced on January 2, 2004.
Class A shares, Class B shares, Class C shares and Class I shares bear the same
voting (except for issues that relate solely to one class), dividend,
liquidation and other rights and conditions. Each class of shares, other than
Class I shares, bears distribution and/or service fee payments under a
distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I shares are
not subject to a distribution or service fee.

The Fund's investment objective is to realize current income consistent with
reasonable opportunity for future growth of capital and income.

The Fund also invests in foreign securities which carry certain risks that are
in addition to the usual risks inherent in domestic instruments. These risks
include those resulting from currency fluctuations, future adverse political and
economic developments and possible imposition of currency exchange blockages or
other foreign governmental laws or restrictions. These risks are likely to be
greater in emerging markets than in developed markets. The ability of issuers of
debt securities held by the Fund to meet their obligations may be affected by
economic and political developments in a specific country, industry or region.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or brokers selected by the Fund's Manager, whose prices reflect
broker/dealer supplied valuations and electronic data processing techniques, if
such prices are deemed by the Fund's Manager to be representative of market
values, at the regular close of business of the New York Stock Exchange. Equity
securities are valued at the latest quoted sales prices as of the close of
trading on the New York Stock Exchange (generally 4:00 p.m. Eastern time) on the
valuation date; such securities not traded on the valuation date are valued at
the mean of the latest quoted bid and asked prices. Prices normally are taken
from the principal market in which each security trades. Temporary cash
investments acquired over 60 days to maturity are valued using the latest bid
prices or using valuations based on a matrix system (which considers such
factors as security prices, yields, maturities, and ratings), both as furnished
by independent pricing services. Other temporary cash investments are valued at
amortized cost, which approximates market value. Securities for which market
quotations are not readily available are valued by methods deemed in good faith
by Board of Trustees to represent fair value. Reasons for which securities may
be valued in this manner include, but are not limited to, trading for a security
has been halted or suspended, a security has been de-listed from a national
exchange, or trading on a security's principal market is temporarily closed at a
time when under normal conditions it would be open. The Fund did not hold
securities at October 31, 2005, that were valued in such manner.

Certain events may occur between the time that foreign markets close, on which
securities held by the Fund principally trade, and the time at which the Fund's
NAV is calculated. These events may include, but are not limited to, situations
relating to a single issue in a market sector, significant fluctuations in U.S.
or foreign markets, natural disasters, armed conflicts, governmental actions or
other developments not tied directly to the securities markets. Should the
Manager or Subadvisor conclude that such events may have effected the accuracy
of the last price reported on the local foreign market, the Manager or
Subadvisor may, pursuant to procedures adopted by the Fund, adjust the value of
the local price to reflect the impact on the price of such securities as a
result of such events.

(B) MORTGAGE DOLLAR ROLLS.  The Fund enters into mortgage dollar roll ("MDR")
transactions in which it sells mortgage-backed securities ("MBS") from its
portfolio to a counterparty from whom it simultaneously agrees to buy a similar
security on a delayed delivery basis. The MDR transactions of the Fund are
classified as purchase and sale transactions. The securities sold in connection
with the MDRs are removed from the portfolio and a realized gain or loss is
recognized. The securities the Fund has agreed to

 26   MainStay Total Return Fund


acquire are included at market value in the portfolio of investments and
liabilities for such purchase commitments are included as payables for
investments purchased. During the roll period, a Fund forgoes principal and
interest on the securities. A Fund is compensated by the difference between the
current sales price and the forward price for the future purpose as well as by
the earnings on the cash proceeds of the initial sale. MDRs may be renewed
without physical delivery of the securities subject to the contract. The Fund
maintains a segregated account with its custodian containing securities from its
portfolio having a value not less than the repurchase price, including accrued
interest. MDR transactions involve certain risks, including the risk that the
MBS returned to the Fund at the end of the roll, while substantially similar,
could be inferior to what was initially sold to the counterparty.

(C) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See Note 7.)

(D) RESTRICTED SECURITIES.  A restricted security is a security which has been
purchased through a private offering and cannot be resold to the general public
without prior registration under the Securities Act of 1933 (the "1933 Act").
The Fund does not have the right to demand that such securities be registered.
Disposal of these securities may involve time-consuming negotiations and expense
and prompt sale at an acceptable price may be difficult. (See Note 7.)

(E) LOAN ASSIGNMENTS, PARTICIPATIONS AND COMMITMENTS.  The Fund invests in loan
assignments and loan participations. Loan assignments and participations are
agreements to make money available (a "commitment") to a borrower in a specified
amount, at a specified rate and within a specified time. Such loan assignments
and participations are typically senior, secured and collateralized in nature.
The Fund records an investment when the borrower withdraws money and records
interest as earned. These loans pay interest at rates which are periodically
reset by reference to a base lending rate plus a spread. These base lending
rates are generally the prime rate offered by a designated U.S. bank or London
InterBank Offered Rate (LIBOR).

The loans in which the Fund invests are generally readily marketable, but may be
subject to some restrictions on resale. The Fund may be contractually obligated
to receive approval from the agent bank and/or borrower prior to the sale of
these investments.

The Fund assumes the credit risk of the Borrower, the Selling Participant and
any other persons interpositioned between the Fund and the Borrower
("Intermediate Participants"). In the event that the Borrower, Selling
Participant or Intermediate Participants becomes insolvent or enters into
bankruptcy, the Fund may incur certain costs and delays in realizing payment, or
may suffer a loss of principal and/or interest.

Unfunded commitments represent the remaining obligation of the Fund to the
Borrower. At any point in time, up to the maturity date of the issue, the
Borrower may demand the unfunded portion. These unfunded amounts are recorded in
memorandum accounts.

(F) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are withheld at the source.

(G) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
quarterly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

The following table discloses the current year reclassification between
accumulated undistributed net investment income, accumulated net realized gain
and additional paid-in-capital, arising from permanent differences; net assets
at October 31, 2005 are not affected.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

The reclassifications for the Fund are primarily due to real estate investment
trust investments, paydowns and foreign currency gain (loss).

(H) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method and include gains
and losses from repayments of principal on mortgage-backed securities. Dividend
income is recognized on the ex-dividend date and interest income is accrued as
earned. Discounts and premiums on securities purchased, other than short-term
securities, for the Fund are accreted and amortized, respectively, on the
constant yield method over the life of the respective securities or, in the case
of a callable security, over the period to the first date of call. Discounts and
premiums on short-term securities are accreted and amortized, respectively, on
the straight line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(I) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its portfolio securities or foreign currencies. Premiums are received
and are recorded as liabilities. The liabilities are subsequently adjusted and
unrealized appreciation or depreciation is recorded to reflect the current value
of the options written. Premiums received from writing options which expire are
treated as realized gains. Premiums received from writing options which are
exercised or are cancelled in closing purchase transactions are added to the
proceeds or netted against the amount paid on the transaction to determine the
realized gain or loss. By writing a covered call option, in exchange for the
premium, the Fund foregoes the opportunity for capital appreciation above the
exercise price should the market price of the underlying security or foreign
currency increase but, as long as the obligation as a writer continues, have
retained the risk of loss should the price of the underlying security decline.
By writing a covered put option, the Fund, in exchange for the premium, accepts
the risk of decline in the market value of the underlying security or foreign
currency below the exercise price. After writing a put option, the Fund may
incur a loss equal to the difference between the exercise price of the option
and the sum of the market value of the underlying security plus the premium
received from the sale of the option. A call option may be covered by the call
writer's owning the underlying security throughout the option period. A call
option may also be covered by the call writer's maintaining liquid assets valued
at greater than the exercise price of the call written, in a segregated account
with its custodian.

The Fund may purchase call and put options on its portfolio securities. The Fund
may purchase call options to protect against an increase in the price of the
security it anticipates purchasing. The Fund may purchase put options on its
securities to protect against a decline in the value of the security or to close
out covered written put positions. The Fund may also purchase options to seek to
enhance returns. Risks may arise from an imperfect correlation between the
change in market value of the securities held by the Fund and the prices of
options relating to the securities purchased or sold by the Fund and from the
possible lack of a liquid secondary market for an option. The maximum exposure
to loss for any purchased option is limited to the premium initially paid for
the option.

(J) FOREIGN CURRENCY TRANSACTIONS.  The books and records of the Fund are kept
in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at
the mean between the buying and selling rates last quoted by any major U.S. bank
at the following dates:


(i)  market value of investment securities, other assets and liabilities--at the
     valuation date,

(ii) purchases and sales of investment securities, income and expenses--at the
     date of such transactions.

The assets and liabilities are presented at the exchange rates and market values
at the close of the period. The realized and unrealized changes in net assets
arising from fluctuations in exchange rates and market prices of securities are
not separately presented. The unrealized changes in net assets arising from
fluctuations in exchange rates and market prices of securities are not
separately presented.

Net realized gain (loss) on foreign currency transactions represents net gains
and losses on foreign currency forward contracts, net currency gains or losses
realized as a result of differences between the amounts of securities sale
proceeds or purchase cost, dividends, interest and withholding taxes as recorded
on the Fund's books, and the U.S. dollar equivalent amount actually received or
paid. Net currency gains or losses from valuing such foreign currency
denominated assets and liabilities, other than investments, are reflected in
unrealized foreign exchange gains or losses at period end exchange rates.

(K) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(L) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

 28   MainStay Total Return Fund


(M) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.64% on assets up to $500 million and
0.60% on assets in excess of $500 million. Effective August 1, 2005, the Manager
has entered into a written expense limitation agreement, under which the Manager
has agreed to reimburse the expenses of the Fund so that the total operating
expenses (excluding taxes, interest, litigation, extraordinary expenses, and
brokerage and other transaction expenses relating to the purchase or sale of
portfolio investments) do not exceed, on an annualized basis, 1.19% of the
average daily net assets of the Class A shares. An equivalent reimbursement, in
an equal amount of basis points, will be applied to the other share classes. The
Manager, within three years of incurring such expenses, may recoup the amount of
any management fee waiver or expense reimbursement from the Fund pursuant to
this agreement if such recoupment does not cause the Fund to exceed the expense
limitations. At October 31, 2005, the Fund had $177,401 of recoupment available.
This amount is available until October 31, 2008. This expense limitation may be
modified or terminated only with the approval of the Board of Trustees. Prior to
August 1, 2005 and after December 1, 2004, NYLIM agreed to voluntarily reimburse
the expenses of the Fund so that total annual fund operating expenses would not
exceed on an annualized basis 1.19% of the average daily net assets of the Class
A and such that there would be an equivalent reduction for the other classes of
shares. For the year ended October 31, 2005, the Manager earned fees from the
Fund in the amount of $5,168,565 and waived its fees and/or reimbursed expenses
in the amount of $975,313.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager pays the Subadvisor a monthly fee of 0.32% of the average
daily net assets of the Fund on assets up to $500 million and 0.30% on assets in
excess of $500 million. To the extent the Manager has agreed to reimburse
expenses of the Fund, the Subadvisor has voluntarily agreed to do so
proportionately.

(B) DISTRIBUTION AND SERVICE FEES.  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC (the "Distributor"), an
indirect wholly-owned subsidiary of New York Life. The Fund, with respect to
each class of shares, other than Class I shares, has adopted distribution plans
(the "Plans") in accordance with the provisions of Rule 12b-1 under the 1940
Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee from
the Fund at an annual rate of 0.25% of the average daily net assets of the
Fund's Class A shares, which is an expense of the Class A shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The Plans provide that the Class B and Class C shares of the Fund also
incur a service fee at the annual rate of 0.25% of the average daily net asset
value of the Class B or Class C shares of the Fund. Class I shares are not
subject to a distribution or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $306,171 for the year
ended October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $4,835, $363,647 and $370, respectively, for the year ended October
31, 2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is
responsible. Transfer agent expenses incurred by the Fund for the year ended
October 31, 2005, amounted to $2,805,362.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000

                                                    www.MAINSTAYfunds.com     29

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

for each Board meeting, $1,000 for each Committee meeting and $500 for each
Valuation Subcommittee telephonic meeting attended plus reimbursement for travel
and out-of-pocket expenses. The Lead Non-Interested Trustee is also paid an
annual retainer fee of $20,000. The Audit and Compliance Committee Chairman
receives an additional $2,000 for each meeting of the Audit and Compliance
Committee attended and the Chairpersons of the Brokerage and Expense Committee,
Operations Committee and Performance Committee each receive an additional $1,000
for each meeting of the Brokerage and Expense Committee, Operations Committee
and Performance Committee attended, respectively. In addition, each
Non-Interested Trustee is paid $1,000 for attending meetings of the Non-
Interested Trustees held in advance of or in connection with Board/Committee
meetings. The Trust allocates trustees fees in proportion to the net assets of
the respective Funds. Thus the Fund only pays a portion of the fees identified
above.
(F) CAPITAL.  At October 31, 2005 New York Life held shares of Class A and Class
I with net values of $5,360,090 and $1,090, respectively. This represents 5.5%
and 14.6% of Class A and Class I net assets, respectively and 0.7% of the Fund's
total net assets at October 31, 2005.

(G) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$21,316 for the year ended October 31, 2005.

The Fund pays the Manager a monthly fee for certain pricing and recordkeeping
services provided under the Accounting Agreement at the annual rate of 1/20 of
1% for the first $20 million of average monthly net assets, 1/30 of 1% of the
next $80 million of average monthly net assets and 1/100 of 1% of any amount in
excess of $100 million of average monthly net assets. Fees for these services
provided to the Fund by the Manager amounted to $109,476 for the year ended
October 31, 2005.

NOTE 4--CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, State Street Bank and Trust Company acted as custodian for
the Fund.

NOTE 5--FEDERAL INCOME TAX:

The Fund and certain affiliated funds maintain a line of credit of $160,000,000

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

NOTE 10--OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those arrangements and certain other levels of trading
by fund shareholders over the period from 1999 to 2003 may have had on the
funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.9 million to nine MainStay funds. The amount paid to the MainStay
Total Return Fund was $102,000. NYLIM has also agreed to reimburse or pay all
expenses relating to the Board of Trustees' review of this matter and has paid
substantially all of the costs associated with the other regulatory matters
described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Total Return Fund ("the Fund"),
one of the funds constituting The MainStay Funds, as of October 31, 2005, and
the related statement of operations for the year then ended, and the statements
of changes in net assets and financial highlights for each of the years in the
two-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Total Return Fund of The MainStay Funds as of October 31, 2005, the
results of its operations for the year then ended, and the changes in its net
assets and financial highlights for each of the years in the two-year period
then ended, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreement, the Board of Trustees requested and received from the
Manager and Subadvisor, and reviewed, a wide variety of information. The
Trustees also requested and received information from outside data providers and
information and analysis from a third party consultant. The Trustees considered
various industry and regulatory trends in their deliberations. In considering
approval of these Agreements, and in evaluating the fairness of the compensation
to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and Subadvisor have provided historically to the Fund, and also
generally to other series of the Trust. The Manager's services to the Trust have
included investment management services, including the selection and supervision
of portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the
day-to-day management of the portfolio, providing reports to the Manager, and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. In considering the Manager's
and Subadvisor's practices relating to best execution of portfolio trades, the
Board reviewed reports of the Fund's Brokerage Committee including with respect
to analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager, the Subadvisor and certain other service
providers, as well as the Subadvisor's attention to its compliance program. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager and Subadvisor were such that, in the context of the Board's overall
review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's underperformance when compared
over several time periods with funds concluded by Trustees to be peers of the
Fund, as well as changes to the Fund's investment process and its improving
investment performance relative to those funds.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees noted the Manager's
agreement to limit the Fund's net expenses to a certain level with respect to
the Fund, with the expectation that the Manager intended, over time, to
implement measures designed to reduce the Trust's transfer agency fees. The
Trustees considered certain benefits expected for, and risks borne by, the
Manager and its affiliates, including benefits from soft dollar arrangements.
The Trustees considered the services provided to the Fund by affiliates of the
Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the
benefits to the Manager and its affiliates from those relationships. The
information provided to the Trustees indicated that the profitability to the
Manager and its affiliates arising directly from those other agreements was not
excessive. The Trustees acknowledged certain benefits to the reputation of the
Manager and its affiliates, as well to that of the Trust, from their association
with each other.

The Trustees, in considering economies of scale, reviewed information showing
that the asset size of the Fund had decreased in size over the past five years.
The Trustees discussed the extent to which economies of scale were

 36   MainStay Total Return Fund


projected by the Manager to be realized were the Fund to grow, or as the Trust
grows overall, noting in particular the Manager's plans for marketing and
distributing shares of various series of the Trust. They noted the Manager's
willingness to implement contractual breakpoints, and that the contractual
breakpoints in place for the management fee were intended to provide that the
Fund's shareholders would share in benefits from economies of scale arising from
the growth of Fund assets. The Trustees noted that the Fund's contractual
management fee had been reduced in accordance with the terms of the breakpoint
schedule applicable to the Fund. Acknowledging the difficulty of forecasting
economies of scale, the Trustees generally expressed an intention to monitor the
Manager's profitability and consider the application of fee breakpoints or other
appropriate measures as the Board may determine from time to time. The Trustees
reviewed historical information about changes in the Fund's expense and asset
levels over time, as well as information about certain Fund expenses that would
remain fixed even as Fund assets increase and, therefore, provide the Fund with
benefits from economies of scale as the Fund grows. The Trustees noted that, to
the extent the Fund's gross expenses currently are higher than its net expenses,
economies of scale achieved through an increase in the Fund's assets might not
directly benefit the Fund through lower net expenses. The Trustees considered
various information about transfer agency expenses, including information
showing that transfer agency fees of the Fund and a significant number of series
of the Trust (although not every such series or with respect to every share
class of each series) tended to be high, when aggregated and expressed as a
percentage of the assets of certain series, compared to the mutual fund industry
average according to certain studies reviewed by the Board and, therefore,
adversely affected gross expense ratios. The Board received information about
potential effects on the Manager were it to subsidize certain portions of the
Trust's transfer agency fees. The Trustees noted that a significant number of
shareholders of the Trust's series had small amounts invested in the series, and
have considered measures intended to increase average shareholder account size
and/or otherwise reduce the Trust's transfer agency fees and expenses, including
steps that the Manager has taken to encourage shareholders to consolidate or
close small accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts, that had investment objectives similar to
that of the Fund. The Trustees took into account information provided by the
Manager or Subadvisor about the relative scope of services provided to the Fund
and to those accounts or explanations about the accounts' histories. In
considering the extent of the fees received by the Manager and Subadvisor for
providing services to the Fund, the Trustees evaluated factors such as the fees
and expenses borne by other registered funds in the market pursuing strategies
generally similar to those followed by the Fund. The Trustees considered the
Fund's historical and proposed contractual and net management fees, its
anticipated gross and net expense ratios, and various components of that expense
ratio, in comparison to other funds in comparison groupings prepared by outside
data providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
Manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

 2   MainStay Value Fund


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.

At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay
introduced four new Asset Allocation Funds, each with a distinct risk/reward
profile.

The report that follows takes a closer look at the specific securities and
decisions that affected your MainStay Fund investment during the 12 months ended
October 31, 2005. We hope that you will review the report carefully to gain
greater insight into your Fund's performance, holdings, and management style.

Sincerely,


/S/ CHRISTOPHER O. BLUNT


Christopher O. Blunt
President

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee, and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Class R1 shares are sold with
no initial sales charge or CDSC and have no annual 12b-1 fee. Class R2 shares
are sold with no initial sales charge or CDSC and have an annual 12b-1 fee of
..25%. Class R1 and Class R2 shares are available only through
corporate-sponsored retirement programs, which include certain minimum program
requirements. Performance figures reflect certain fee waivers and/or expense
limitations, without which total returns may have been lower. The fee waivers
and/or expense limitations are contractual and may be modified or terminated
only with the approval of the Board of Trustees. From inception (5/1/86) through
12/31/94 (for Class A, first offered 1/3/95), 8/31/98 (for Class C, first

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY VALUE FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

- - ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31, 2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

- - HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio manager Richard A. Rosen of MacKay Shields LLC

CAN YOU BRIEFLY DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund normally invests at least 65% of its total assets in equity securities
and is not managed primarily to produce current income. In implementing this
strategy, the Fund normally invests in U.S. common stocks that we believe to be
"undervalued," or selling below their value when purchased. The stocks in which
the Fund invests typically pay dividends, but the Fund may invest in
non-dividend-paying stocks if they meet the "undervalued" criterion. Normally,
the Fund invests in stocks that are listed on a national securities exchange or
are traded in the over-the-counter market. When assessing whether a stock is
undervalued, we compare the stock's market price to the company's cash flow and
interest coverage ratios, the company's book value, the estimated value of the
company's assets, the company's growth rates, and its future earnings. We may
sell stocks if we no longer believe they will contribute to meeting the
investment objective of the Fund.

During the 12-month reporting period, all of the assets and liabilities of
MainStay Research Value Fund were transferred to MainStay Value Fund in exchange
for shares of MainStay Value Fund.

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED
OCTOBER 31, 2005?

During the 12-month reporting period, stocks generally advanced, despite
political events and energy price fluctuations. Value stocks outperformed growth
stocks at all capitalization levels. Crude-oil prices rallied to $69.81 per
barrel and natural-gas prices broke $14 per million Btu before backing off
somewhat. Major hurricanes affected supply-and-demand dynamics by damaging oil
rigs and petrochemical plants. The price of gasoline rose to more than $3 a
gallon, which threatened to slow consumer spending. Although hurricane-related
stocks--including retailers, insurers, and companies on the Gulf Coast--were
weakened, the long-term economic impact appeared to be manageable.

The Federal Open Market Committee raised the targeted federal funds rate eight
times during the 12-month reporting period, with a 25-basis-point increase on
each occasion. (A basis point is one-hundredth of a percentage point.) On
October 31, 2005, the federal funds target rate stood at 3.75%. During the
reporting period, the yield curve flattened to reflect concern over a potential
recession. Yet the most recent gross domestic product data suggests that the
overall economy has remained resilient.

WHICH FUND HOLDINGS WERE PARTICULARLY STRONG DURING THE REPORTING PERIOD?

We saw strong results from energy-related holdings Transocean, Pride
International, ENSCO International, and Rowen. Higher energy prices,
hurricane-related supply pressures, and higher day rates benefited these stocks.
We trimmed the Fund's positions in Transocean, ENSCO International, and Rowen as
the stocks approached our price targets.

HOW DID THE FUND'S FINANCIAL STOCKS PERFORM?

We saw positive results from our stock selection in the financials sector.
Operating improvements at Prudential Financial helped the company post strong
earnings gains. The company shed noncore insurance operations and made
cost-effective Asian acquisitions to help improve its return on equity. The
Hartford Financial Services Group, St. Paul Travelers, and AFLAC were other
insurance companies that showed strong results. The Goldman Sachs Group and
State Street are two capital markets stocks that helped the Fund's performance.

WERE THERE OTHER SUCCESS STORIES?

Motorola benefited from good handset sales, in-creased market share, and
excitement over a new product line-up. The company strengthened its balance
sheet under the leadership of a new CEO. We pared back the Fund's position as
the stock approached our price target. In the information technology sector,
Texas Instruments showed strength from the Fund's initial purchase in January
through the end of October. Wireless semiconductor sales and a share buyback
program accelerated during the reporting period. Among consumer-related stocks,
supermarket Kroger and food manufacturer Cadbury Schwepps were both strong.

WHICH STOCKS DETRACTED FROM THE FUND'S PERFORMANCE DURING THE REPORTING PERIOD?

Clothing retailer The Gap clearly hit a weak spot in its sales recovery when the
fall season got off to a slower-than-expected start. Higher gasoline prices and
slipping consumer confidence also hurt the stock. We are optimistic about better
sales trends during the holiday season, and we believe that low valuations, a
share repurchase program, and a strong balance sheet make the stock attractive.
Shares of Molson Coors Brewing fell from our initial purchase in March until our
sale later in the reporting period. When sales slowed and the company showed
evidence of merger-integration difficulties, we sold the Fund's entire position
in the stock.

 8   MainStay Value Fund


Pending generic-drug litigation and weaker-than-expected guidance for 2006 took
a toll on Pfizer. Nevertheless, we like the stock for its upside potential,
all-time low valuation, strong free cash flow, and 3% yield. We have hedged
nearly all of the Fund's position using protective put contracts to limit
downside exposure.

Although we purchased the stock at what looked like a low price, printer
manufacturer Lexmark continued to report operating problems and inventory
issues. We concluded that the company's downside risk outweighed its upside
potential, and we sold the Fund's entire position in late October 2005.

Alcoa faced contracting margins because of higher energy prices and weakness in
some end markets. Glass manufacturer Owens-Illinois was also hurt by higher
costs. We sold the Fund's entire position in both of these stocks. Verizon
Communications faced stronger competition in its wireline business, but
continued to provide a high dividend yield. We used lower valuations to add to
the Fund's position late in the reporting period.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?

After selling many energy stocks that had reached our price targets, by October
31, 2005, the Fund was only slightly overweighted relative to the Russell
1000(R) Index in the energy sector. The Fund was overweighted in consumer
staples and information technology, where we continue to find select value
opportunities. At the end of the reporting period, the Fund was also
overweighted in telecommunications services, where we judge asset value to be a
near-term catalyst in a number of portfolio holdings. Our belief that some major
drug companies have favorable risk/reward characteristics has supported our
decision to overweight health care stocks.

With gasoline prices finally having an impact on consumer spending, the Fund
closed the reporting period underweighted in consumer discretionary stocks. We
have, however, begun to find select opportunities in the sector. Since we have
yet to find much value in utilities, the Fund remained underweighted relative to
the Index in the sector. At the end of October 2005, the Fund was cautiously
underweighted among interest-rate sensitive financials and REITS. The Fund was
also underweighted relative to the Russell 1000(R) Index in industrials and
materials.

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 Value
Fund (the "Fund"), a diversified fund.

The Fund currently offers six classes of shares. Class A shares, Class B shares,
Class C shares, Class I shares, Class R1 shares and Class R2 shares. Class A
shares, whose distribution commenced on January 3, 1995, are offered at net
asset value per share plus an initial sales charge. No sales charge applies on
investments of $1 million or more (and certain other qualified purchases) in
Class A shares, but a contingent deferred sales charge is imposed on certain
redemptions of such shares within one year of the date of purchase. Class B
shares and Class C shares are offered without an initial sales charge, although
a declining contingent deferred sales charge may be imposed on redemptions made
within six years of purchase of Class B shares and within one year of purchase
of Class C shares. Class I, Class R1 and Class R2 shares are not subject to a
sales charge. Distribution of Class B shares and Class C shares commenced on May
1, 1986 and September 1, 1998, respectively. Distribution of Class I shares,
Class R1 shares and R2 shares commenced on January 2, 2004. The six classes of
shares bear the same voting (except for issues that relate solely to one class),
dividend, liquidation, and other rights and conditions except that Class B
shares and Class C shares are subject to higher distribution fee rates than
Class A shares and Class R2 shares under a distribution plan pursuant to Rule
12b-1 under the 1940 Act. Class I shares and Class R1 shares are not subject to
a distribution or service fee. Class R1 and Class R2 shares are authorized to
pay to New York Life Investment Management LLC, its affiliates, or third-party
service providers, as compensation for services rendered to shareholders of
Class R1 or Class R2 shares, a shareholder service fee.

The Fund's investment objective is to realize maximum long-term total return
from a combination of capital growth and income.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on the valuation date; such securities not
traded on the valuation date are valued at the mean of the latest quoted bid and
asked prices. Prices normally are taken from the principal market in which each
security trades. Temporary cash investments acquired over 60 days to maturity
are valued using the latest bid prices or using valuations based on a matrix
system (which considers such factors as security prices, yields, maturities, and
ratings), both as furnished by independent pricing services. Other temporary
cash investments are valued at amortized cost, which approximates market value.
Securities for which market quotations are not readily available are valued by
methods deemed in good faith by Board of Trustees to represent fair value.
Reasons for which securities may be valued in this manner include, but are not
limited to, trading for a security has been halted or suspended, a security has
been de-listed from a national exchange, or trading on a security's principal
market is temporarily closed at a time when under normal conditions it would be
open. The Fund did not hold securities at October 31, 2005, that were valued in
such manner.

(B) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (See Note 6.)

(C) PURCHASED AND WRITTEN OPTIONS.  The Fund may write covered call and put
options on its portfolio securities or foreign currencies. Premiums are received
and are recorded as liabilities. The liabilities are subsequently adjusted and
unrealized appreciation or depreciation is recorded to reflect the current value
of the options written. Premiums received from writing options which expire are
treated as realized gains. Premiums received from writing options which are
exercised or are cancelled in closing purchase transactions are added to the
proceeds or netted against the amount paid on the transaction to determine the
realized gain or loss. By writing a covered call option, in exchange for the
premium, the Fund foregoes the opportunity for capital appreciation above the
exercise price should the market price of the underlying security or foreign
currency increase but, as long as the obligation as a writer continues, have
retained the risk of loss should the price of the underlying security decline.
By writing a covered put option, the Fund, in exchange for the premium, accepts
the risk of decline in the market value of the underlying security or foreign
currency below the exercise price. After writing a put option, the Fund may

 18   MainStay Value Fund


incur a loss equal to the difference between the exercise price of the option
and the sum of the market value of the underlying security plus the premium
received from the sale of the option. A call option may be covered by the call
writer's owning the underlying security throughout the option period. A call
option may also be covered by the call writer's maintaining liquid assets valued
at greater than the exercise price of the call written, in a segregated account
with its custodian.

The Fund may purchase call and put options on its portfolio securities. The Fund
may purchase call options to protect against an increase in the price of the
security it anticipates purchasing. The Fund may purchase put options on its
securities to protect against a decline in the value of the security or to close
out covered written put positions. The Fund may also purchase options to seek to
enhance returns. Risks may arise from an imperfect correlation between the
change in market value of the securities held by the Fund and the prices of
options relating to the securities purchased or sold by the Fund and from the
possible lack of a liquid secondary market for an option. The maximum exposure
to loss for any purchased option is limited to the premium initially paid for
the option.

(D) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are withheld at the source.

(E) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
quarterly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

(F) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on short-term securities are accreted and amortized,
respectively, on the straight line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(G) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(H) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(I) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would
involve future claims that may be made against the Fund that have not yet
occurred. Based on experience, management is of the view that the risk of loss
in connection with these potential indemnification obligations is remote;
however, there can be no assurance that material liabilities related to such
obligations will not arise in the future that could adversely impact the Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. MacKay
Shields LLC (the "Subadvisor"), a registered investment advisor and indirect
wholly-owned subsidiary of New York Life, is responsible for the day-to-day
portfolio management of the Fund.

                                                    www.MAINSTAYfunds.com     19

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.72% on assets up to $200 million, 0.65%
on assets from $200 million to $500 million and 0.50% on assets in excess of
$500 million. Effective August 1, 2005, the Manager has entered into a written
expense limitation agreement, under which the Manager has agreed to reimburse
the expenses of the Fund so that the total operating expenses (excluding taxes,
interest, litigation, extraordinary expenses, and brokerage and other
transaction expenses relating to the purchase or sale of portfolio investments)
do not exceed, on an annualized basis, 1.17% of the average daily net assets of
the Class A shares. An equivalent reimbursement, in an equal amount of basis
points, will be applied to the other share classes. The Manager, within three
years of incurring such expenses, may recoup the amount of any management fee
waiver or expense reimbursement from the Fund pursuant to this agreement if such
recoupment does not cause the Fund to exceed the expense limitations. At October
31, 2005, the Fund had $235,721 of recoupment available. This amount is
available until October 31, 2008. This expense limitation may be modified or
terminated only with the approval of the Board of Trustees. Prior to August 1,
2005 and effective December 1, 2004, NYLIM agreed to voluntarily reimburse the
expenses of the Fund so that the total operating expenses for Class A shares
would not exceed on an annualized basis 1.22% of the average daily net assets of
the Class A shares, and such that there would be an equivalent reduction for the
other classes of shares. For the year ended October 31, 2005, the Manager earned
fees from the Fund in the amount of $4,582,549 and waived its fee and/or
reimbursed expenses in the amount of $476,057.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and MacKay
Shields, the Manager pays the Subadvisor a monthly fee at an annual rate of
0.36% of the Fund's average daily net assets on assets up to $200 million,
0.325% on assets from $200 million to $500 million and 0.25% on assets in excess
of $500 million. To the extent the Manager has agreed to reimburse expenses of
the Fund, the Subadvisor has voluntarily agreed to do so proportionately.

(B) DISTRIBUTION, SERVICE AND SHAREHOLDER SERVICE FEES.  The Trust, on behalf of
the Fund, has a Distribution Agreement with NYLIFE Distributors LLC (the
"Distributor"), an indirect wholly-owned subsidiary of New York Life. The Fund,
with respect to Class A, Class B, Class C, and Class R2 shares, has adopted
distribution plans (the "Plans") in accordance with the provisions of Rule 12b-1
under the 1940 Act. Pursuant to the Class A and Class R2 Plan, the Distributor
receives a monthly fee from the Fund at an annual rate of 0.25% of the average
daily net assets of the Fund's Class A and Class R2 shares, which is an expense
of the Class A and Class R2 shares of the Fund for distribution or service
activities as designated by the Distributor. Pursuant to the Class B and Class C
Plans, the Fund pays the Distributor a monthly fee, which is an expense of the
Class B and Class C shares of the Fund, at the annual rate of 0.75% of the
average daily net assets of the Fund's Class B and Class C shares. The Plans
provide that the Class B and Class C shares of the Fund also incur a service fee
at the annual rate of 0.25% of the average daily net asset value of the Class B
or Class C shares of the Fund. Class I shares are not subject to a distribution
or service fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

The Fund has adopted a shareholder services plan with respect to Class R1 and
Class R2 shares. Under the terms of this plan, Class R1 and Class R2 shares are
authorized to pay to NYLIM, its affiliates, or independent third-party
providers, as compensation for services rendered, a shareholder services fee at
the rate of 0.10% of the average daily net assets of the Fund's Class R1 and R2
shares.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $59,894 for the year ended
October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $6,542, $302,656 and $1,323, respectively, for the year ended October
31, 2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC ("NYLIM Service"), an affiliate of NYLIM, is the Fund's
transfer, dividend disbursing and shareholder servicing agent. NYLIM Service has
entered into an agreement with Boston Financial Data Services ("BFDS") pursuant
to which BFDS will perform certain of the services for which NYLIM Service is

NOTE 11--OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those arrangements and certain other levels of trading
by fund shareholders over the period from 1999 to 2003 may have had on the
funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.9 million to nine MainStay funds. The amount paid to the MainStay
Value Fund was $374,000. NYLIM has also agreed to reimburse or pay all expenses
relating to the Board of Trustees' review of this matter and has paid
substantially all of the costs associated with the other regulatory matters
described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Value Fund ("the Fund"), one of
the funds constituting The MainStay Funds, as of October 31, 2005, and the
related statement of operations for the year then ended, and the statements of
changes in net assets and financial highlights for each of the years in the
two-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The financial highlights for the periods presented through
October 31, 2003, were audited by other auditors, whose report dated December
18, 2003, expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Value Fund of The MainStay Funds as of October 31, 2005, the results of
its operations for the year then ended, and the changes in its net assets and
financial highlights for each of the years in the two-year period then ended, in
conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreement, the Board of Trustees requested and received from the
Manager and Subadvisor, and reviewed, a wide variety of information. The
Trustees also requested and received information from outside data providers and
information and analysis from a third party consultant. The Trustees considered
various industry and regulatory trends in their deliberations. In considering
approval of these Agreements, and in evaluating the fairness of the compensation
to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager and Subadvisor have provided historically to the Fund, and also
generally to other series of the Trust. The Manager's services to the Trust have
included investment management services, including the selection and supervision
of portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the
day-to-day management of the portfolio, providing reports to the Manager, and
reviewing certain aspects of Fund filings. The Trustees considered, among other
things, the Manager's and Subadvisor's management, personnel, resources,
operations and portfolio management capabilities. In considering the Manager's
and Subadvisor's practices relating to best execution of portfolio trades, the
Board reviewed reports of the Fund's Brokerage Committee including with respect
to analysis prepared by Plexus Group. The Trustees considered the Manager's
supervision of the Fund's service providers and its attention to the compliance
program of the Trust, the Manager, the Subadvisor and certain other service
providers, as well as the Subadvisor's attention to its compliance program. The
Trustees noted the generally favorable conclusions of financial services
research firm DALBAR Inc. of the services, investor complaint levels, and
communications that NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
the Manager, has provided to Trust shareholders. A majority of the Trustees,
including a majority of the Non-Interested Trustees, concluded that, overall,
the nature, extent and quality of the services expected to be provided by the
Manager and Subadvisor were such that, in the context of the Board's overall
review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Trustees also
considered information contained in management presentations to the Board's
Performance Committee over the course of the past year. The Board's decision
took account of, among other things, the Fund's underperformance when compared
over several time periods with funds concluded by Trustees to be peers of the
Fund, as well as steps the Subadvisor had taken to improve performance.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees reviewed information about the compensation structure
for portfolio managers employed by the Manager and assessed whether that
structure appears to align portfolio manager compensation with the long-term
objectives of the Fund's shareholders. The Trustees noted the Manager's
agreement to limit the Fund's net expenses to a certain level with respect to
the Fund, with the expectation that the Manager intended, over time, to
implement measures designed to reduce the Trust's transfer agency fees. The
Trustees considered certain benefits expected for, and risks borne by, the
Manager and its affiliates, including benefits from soft dollar arrangements.
The Trustees considered the services provided to the Fund by affiliates of the
Manager, NYLIFE Distributors and NYLIM Service, under other agreements, and the
benefits to the Manager and its affiliates from those relationships. The
information provided to the Trustees indicated that the profitability to the
Manager and its affiliates arising directly from those other agreements was not
excessive. The Trustees acknowledged certain benefits to the reputation of the
Manager and its affiliates, as well to that of the Trust, from their association
with each other.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund grows, or as the Trust grows overall,
noting in particular the Manager's plans for marketing and distributing shares
of various series of the Trust. They noted the Manager's willingness to
implement contractual breakpoints, and that the contractual breakpoints in place
for the management fee were intended to provide that the

 28   MainStay Value Fund


Fund's shareholders would share in benefits from economies of scale arising from
the growth of Fund assets. The Trustees noted that the Fund's contractual
management fee had been reduced in accordance with the terms of the breakpoint
schedule applicable to the Fund. Acknowledging the difficulty of forecasting
economies of scale, the Trustees generally expressed an intention to monitor the
Manager's profitability and consider the application of fee breakpoints or other
appropriate measures as the Board may determine from time to time. The Trustees
reviewed historical information about changes in the Fund's expense and asset
levels over time, as well as information about certain Fund expenses that would
remain fixed even as Fund assets increase and, therefore, provide the Fund with
benefits from economies of scale as the Fund grows. The Trustees noted that, to
the extent the Fund's gross expenses currently are higher than its net expenses,
economies of scale achieved through an increase in the Fund's assets might not
directly benefit the Fund through lower net expenses. The Trustees considered
various information about transfer agency expenses, including information
showing that transfer agency fees of the Fund and a significant number of series
of the Trust (although not every such series or with respect to every share
class of each series) tended to be high, when aggregated and expressed as a
percentage of the assets of certain series, compared to the mutual fund industry
average according to certain studies reviewed by the Board and, therefore,
adversely affected gross expense ratios. The Board received information about
potential effects on the Manager were it to subsidize certain portions of the
Trust's transfer agency fees. The Trustees noted that a significant number of
shareholders of the Trust's series had small amounts invested in the series, and
have considered measures intended to increase average shareholder account size
and/or otherwise reduce the Trust's transfer agency fees and expenses, including
steps that the Manager has taken to encourage shareholders to consolidate or
close small accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager and Subadvisor, including other registered funds
and separate institutional accounts, that had investment objectives similar to
that of the Fund. The Trustees took into account information provided by the
Manager or Subadvisor about the relative scope of services provided to the Fund
and to those accounts or explanations about the accounts' histories. In
considering the extent of the fees received by the Manager and Subadvisor for
providing services to the Fund, the Trustees evaluated factors such as the fees
and expenses borne by other registered funds in the market pursuing strategies
generally similar to those followed by the Fund. The Trustees considered the
Fund's historical and proposed contractual and net management fees, its gross
and net expense ratio, and various components of that expense ratio, in
comparison to other funds in comparison groupings prepared by outside data
providers using objective methodologies.

The Trustees acknowledged the historical relationships among the Manager, the
Subadvisor and the Trust and the likely difficulties in implementing an
alternative to the investment management arrangement between the Trust and the
manager. The Trustees also took account of the results of their various
discussions with the Manager concerning the levels of the Fund's contractual and
net management fees and the Fund's anticipated net expense level.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees did not identify any
particular information or any single factor that was controlling, or the
particular weight any Trustee placed on any one factor for purposes of
determining whether to vote in approval of the Agreements. The summary set out
above describes the most important factors, but not all of the matters
considered by the Trustees in coming to their decision regarding the Agreements.
On the basis of their review, a majority of the Trustees and a majority of the
Non-Interested Trustees concluded that each factor they considered, in the
context of all of the other factors they considered, favored renewal of the
Agreements, and it was the judgment of a majority of the Trustees and a majority
of the Non-Interested Trustees that approval of these Agreements was in the best
interests of the Fund and its shareholders.

 2   MainStay Large Cap Growth Fund


MESSAGE FROM
THE PRESIDENT

During the 12 months ended October 31, 2005, most domestic and international
stock markets provided positive overall returns. In the United States, mid-
capitalization stocks outperformed small- and large-cap issues, and investors
tended to prefer value stocks over growth stocks at all capitalization levels.

The U.S. economy continued to advance throughout the reporting period, with
positive growth in gross domestic product and gradually improving labor-market
conditions. In August and September 2005, devastating hurricanes pummeled the
Gulf region, destroying homes, flooding coastal cities, and taking hundreds of
lives. At MainStay, we wish to express our heartfelt concern for the millions of
people who were adversely affected by these natural disasters.

At the end of August, crude-oil prices rose to record levels when rigs and
refineries in the Gulf region faced hurricane-related setbacks. Higher oil and
natural gas prices benefited stocks in the energy sector, but raised concerns
about inflation. To keep the economy on track and inflation at bay, the Federal
Open Market Committee raised the targeted federal funds rate eight times during
the reporting period, with a 25-basis-point increase on each occasion. At the
end of October 2005, the federal funds target rate stood at 3.75%, its highest
level in more than four years.

Since the economy and the markets are constantly changing, managing investments
is a complex task. Fortunately, each MainStay Fund pursues its objective with
the help of a well-defined investment approach that the portfolio managers seek
to apply with discipline, care, and consistency.

At MainStay, we take pride in offering a wide range of Funds suited to the needs
of different types of investors. During the reporting period, MainStay

INVESTMENT AND PERFORMANCE COMPARISON (UNAUDITED)

PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE. PAST PERFORMANCE IS NO
GUARANTEE OF FUTURE RESULTS. BECAUSE OF MARKET VOLATILITY, CURRENT PERFORMANCE
MAY BE LOWER OR HIGHER THAN THE FIGURES SHOWN. INVESTMENT RETURN AND PRINCIPAL
VALUE WILL FLUCTUATE SO THAT UPON REDEMPTION, SHARES MAY BE WORTH MORE OR LESS
THAN THEIR ORIGINAL COST. FOR CURRENT TO THE MOST RECENT MONTH-END PERFORMANCE
INFORMATION, PLEASE CALL 1-800-MAINSTAY (1-800-624-6782) OR VISIT
WWW.MAINSTAYFUNDS.COM. PERFORMANCE DATA SHOWN EXCLUDING SALES CHARGES DOES NOT
REFLECT THE DEDUCTION OF ANY SALES LOAD, WHICH, IF REFLECTED, WOULD REDUCE
PERFORMANCE QUOTED.

Performance tables and graphs do not reflect the deduction of taxes that a
shareholder would pay on distributions or Fund-share redemptions. Total returns
reflect change in share price, reinvestment of dividend and capital-gain
distributions, and maximum applicable sales charges explained in this paragraph.
The graphs assume an initial investment of $10,000 and reflect the deduction of
all sales charges that would have applied for the period of investment. Class A
shares are sold with a maximum initial sales charge of 5.5% and an annual 12b-1
fee of .25%. Class B shares are sold with no initial sales charge, are subject
to a contingent deferred sales charge (CDSC) of up to 5% if redeemed within the
first six years of purchase, and have an annual 12b-1 fee of 1.00%. Class C
shares are sold with no initial sales charge, are subject to a CDSC of 1% if
redeemed within one year of purchase, and have an annual 12b-1 fee of 1.00%.
Class I shares are sold with no initial sales charge or CDSC, have no annual
12b-1 fee, and are generally available to corporate and institutional investors
with a minimum initial investment of $5 million. Class R1 shares are sold with
no initial sales charge or CDSC and have no annual 12b-1 fee.

Class R2 shares are sold with no initial sales charge or CDSC and have an annual
12b-1 fee of .25%. Class R1 and Class R2 shares are only available through
corporate-sponsored retirement programs, which include certain minimum program
requirements. Performance figures reflect certain fee waivers and/or expense
limitations, without which total returns may have been lower. The fee waivers
and/or expense limitations are contractual and may be modified or terminated
only with the approval of the Board of Trustees. On 4/1/05, FMI Winslow Growth
Fund was reorganized as MainStay Large Cap Growth Fund Class A shares. From
inception (7/1/95) through 3/31/05, performance for MainStay Large Cap Growth
Fund Class A shares (first offered 4/1/05) includes the historical performance
of FMI Winslow Growth Fund adjusted to reflect the applicable sales charge and
fees and expenses for Class A shares. From inception (7/1/95) through 3/31/05,
performance for Class B, C, and I shares (first offered 4/1/05), includes the
performance of Class A shares adjusted to reflect the applicable sales charge
(or CDSC) and fees and expenses for Class B, C, and I shares.

Prior to the reorganization, FMI Winslow Growth Fund had no sales charge and its
total net expenses were capped at 1.30%. The total expenses of MainStay Large
Cap Growth Fund are currently capped at 1.40%. Fund performance for all shares
classes prior to 4/1/05 has not been adjusted to reflect the current expense
cap; had it been, the performance shown would have been lower.

On 4/1/05, FMI Winslow Growth Fund was reorganized as MainStay Large Cap Growth
Fund Class A shares. 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.

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY LARGE CAP GROWTH FUND

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from May 1, 2005, to October 31, 2005,
and the impact of those costs on your investment.

EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including redemption fees, if applicable, exchange fees, and sales
charges (loads) on purchases, and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses. This example
is intended to help you understand your ongoing costs (in dollars) of investing
in the Fund and to compare these costs with the ongoing costs of investing in
other mutual funds. The example is based on an investment of $1,000 made at the
beginning of the six-month period and held for the entire period from May 1
through October 31, 2005.

This example illustrates your Fund's ongoing costs in two ways:

ACTUAL EXPENSES
The second and third data columns in the table below provide information about
actual account values and actual expenses. You may use the information in these
columns, together with the amount you invested to estimate the expenses that you
paid during the six months ended October 31,2005. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The fourth and fifth data columns in the table below provide information about
hypothetical account values and hypothetical expenses based on the Fund's actual
expense ratio and an assumed rate of return of 5% per year before expenses,
which is not the Fund's actual return. The hypothetical account values and
expenses may not be used to estimate the actual ending account balances or
expenses you paid for the six-month period shown. You may use this information
to compare the ongoing costs of investing in the Fund and other funds. To do so,
compare this 5% hypothetical example with the 5% hypothetical examples that
appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as
redemption fees, if applicable, exchange fees, or sales charges (loads).
Therefore, the fourth and fifth data columns of the table are useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

Questions answered by portfolio managers Clark J. Winslow, Justin H. Kelly, CFA,
and R. Bart Wear, CFA, of Winslow Capital Management, Inc.

CAN YOU DESCRIBE THE FUND'S INVESTMENT APPROACH?

The Fund invests in companies that have the potential for above-average future
earnings growth. Under normal circumstances, the Fund invests at least 80% of
its total assets in large-capitalization companies. These companies have a
market capitalization in excess of $4.0 billion at the time of purchase and
generally have improving financial returns. In implementing this strategy, we
look for companies that we believe have attractive attributes, such as
consistent and sustainable future growth of revenue and earnings, low financial
leverage with strong cash flow, high return on equity and a low
debt-to-total-capital ratio, management focused on shareholder value, and market
dominance. We use a "bottom-up" investment approach, basing investment decisions
on company specific factors, not general economic conditions. We also employ
strict sell disciplines.

On April 1, 2005, FMI Winslow Growth Fund was reorganized as MainStay Large Cap
Growth Fund Class A shares. Class B, C, I, R1, and R2 shares were subsequently
added. Effective June 29, 2005, MainStay Blue Chip Growth Fund merged into
MainStay Large Cap Growth Fund. The Fund is subadvised by Winslow Capital
Management.

WHAT MAJOR FACTORS INFLUENCED THE STOCK MARKET DURING THE 12 MONTHS ENDED
OCTOBER 31, 2005?

The market rose during the last two months of 2004, as investors' summer worries
about macro factors such as economic growth, corporate earnings, inflation, and
interest rates lessened. During the first quarter of 2005, however, investor
confidence waned amid growing concerns about climbing energy prices, rising
inflation, higher interest rates, and slowing growth in corporate profits. This
led to a pullback in stock prices and weak performance for the first three
months of the year. In late spring 2005, investor sentiment improved when these
worries began to seem excessive and stocks began to rise. This momentum carried
over into the third calendar quarter, although stock prices took a step backward
in October.

WHICH SECTORS AND INDIVIDUAL STOCKS WERE AMONG THE FUND'S STRONG PERFORMERS FOR
THE YEAR ENDED OCTOBER 31, 2005?

We emphasize internal research and employ a bottom-up(1) stock-selection process
to construct the Fund's portfolio. Since the Fund's sector weightings are
primarily a residual of our individual stock deci-
sions, sector results are less important to us than the performance of
individual securities.

The Fund's best individual performers during the reporting period came from the
health care, information technology, and energy sectors. New drug offerings and
a favorable outlook helped Genentech advance strongly during the reporting
period. The Fund's long-held position in pharmacy benefit manager Caremark Rx
also showed excellent performance. In information technology, Google saw its
earnings soar and the stock advanced on the continuing shift to online
advertising. Another important contributor to Fund performance was Corning,
which benefited from a strong position in flat-panel glass displays used in TVs
and computer monitors. In the energy sector, XTO Energy continued to benefit
from favorable growth in natural gas reserves and production and a sharp rise in
the price of natural gas during the reporting period.

WHICH STOCKS DETRACTED FROM THE FUND'S PERFORMANCE?

In a surprise announcement in late February 2005, Biogen Idec withdrew a new
drug that had carried high expectations. The withdrawal caused the company's
share price to decline sharply. Since the withdrawal had removed the company's
major source of growth potential, we sold the Fund's position in the stock.

Shares of Internet-auction giant eBay had an excellent run in calendar year 2004
and we reduced the Fund's position in mid-December 2004 on concerns about the
stock's high valuation. When eBay announced a slightly below-consensus earnings
outlook for 2005, the stock price weakened and we reduced the Fund's position to
control risk.


Typically, the subadvisor intends to invest substantially all of the Fund's
investable assets in domestic securities. However, the Fund is permitted to
invest up to 20% of its net assets in foreign securities. Foreign securities may
be subject to greater risks than U.S. investments, including currency
fluctuations, less-liquid trading markets, greater price volatility, political
and economic instability, less publicly available information, and changes in
tax or currency laws or monetary policy.
1. With bottom-up stock selection, securities are evaluated on their individual
   merits, which may include fundamental characteristics, quantitative measures,
   or both. The process differs from top-down stock selection, which uses broad
   economic, market, or industry considerations to narrow a portfolio's focus to
   specific areas or securities.

                                                     www.MAINSTAYfunds.com     9


Our confidence in Mercury Interactive, a software and services provider to the
business technology-optimization marketplace, waned over the course of the
reporting period, and we eliminated the holding from the Fund.

Zimmer Holdings, which designs and manufactures reconstructive orthopedic
products, suffered from concerns about somewhat slower revenue growth. Although
we have a positive long-term outlook for the company, we reduced the Fund's
position to help control risk should the company's results fall short of our
expectations.

WERE THERE ANY SIGNIFICANT PURCHASES DURING THE REPORTING PERIOD?

We increased the Fund's energy weighting over the course of the reporting
period. This occurred, in part, by adding to the Fund's position in
Schlumberger, an international leader in oil services. When Proctor & Gamble
proposed the acquisition of Gillette, we saw potential in the merger and took
advantage of a price dip to add to the Fund's position in Procter & Gamble.

Since we believe that the managed-care industry has a favorable outlook, we
purchased shares of WellPoint for the Fund. We also expect WellPoint to benefit
from its recent merger with Anthem. In the telecommunication services sector,
the Fund initiated a position in Mexico-based America Movil. The company is the
fastest growing significant cell-phone operator in Latin America, where
penetration levels remain relatively low. Another important purchase in health
care was Alcon, a medical specialty company focused on eye care. The shares
performed well from the time they were purchased through the end of the
reporting period.

WHICH STOCKS DID THE FUND SELL DURING THE REPORTING PERIOD?

In addition to the sales we previously mentioned, we eliminated American
International Group because of legal and accounting uncertainties that developed
during the reporting period. We also sold Royal Caribbean Cruises because rising
oil costs were having a negative effect on the company's earnings growth. We
eliminated the Fund's positions in Teva Pharmaceutical Industries and Manpower
because of questions regarding earnings growth, and we sold the Fund's position
in Univision when television-advertising sales showed less strength than we had
expected.

WERE ANY ADJUSTMENTS MADE TO THE FUND'S SECTOR WEIGHTINGS?

Although sector weightings are primarily a residual of our bottom-up
stock-selection process, we did make a few notable weighting changes during the
reporting period. In information technology, the Fund increased its
underweighted position relative to the Russell 1000(R) Growth Index to an
overweighted position by the end of June. We took profits in several issues,
which reduced the Fund's information technology weighting by the end of October.

The other notable change in the Fund's sector weightings occurred in the energy
sector. The Fund increased its energy weighting to well above that of the
Russell 1000(R) Growth Index in March. Although the size of the Fund's position
was relatively modest during reporting period, strong stock selection helped the
Fund's energy sector holdings outperform related stocks in the Index by a
substantial margin.

The Fund's health care sector weighting remained essentially unchanged during
the reporting period and was similar to the health care sector weighting in the
Index. Even so, the Fund benefited from excellent stock selection. We continued
to underweight major pharmaceutical companies because of slowing earnings
growth. We overweighted the managed care industry (UnitedHealth Group and Well-
Point), pharmacy benefit management (Caremark Rx), and device companies (St.
Jude Medical and Medtronic). These decisions produced a sector total return for
the Fund that was more than twice that of health care stocks in the Index.

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 Large Cap
Growth Fund (the "Fund"), a diversified fund. The Fund commenced operations on
April 1, 2005.

On March 31, 2005 the fund acquired all the net assets of the FMI Winslow Growth
Fund (the "Winslow Fund"), a series of the FMI Mutual Funds, Inc., pursuant to
an Agreement and Plan of Reorganization approved by the shareholders of the
Winslow Fund on March 28, 2005. The acquisition was accomplished by the transfer
of all the assets and liabilities of the Winslow Fund (valued at $5,417,292), to
the Fund. Following the transfer, 1,122,224 shares of the Fund were distributed
to shareholders in liquidation of the Winslow Fund in a tax free exchange for
1,122,224 shares of the Winslow Fund. The reorganization qualifies as a tax-free
reorganization for federal income tax purposes with no gain or loss recognized
by the portfolios or their shareholders. The Fund constitutes the surviving
entity for financial reporting purposes; therefore, it is deemed the "accounting
survivor" for the merger. The financial statements of the Fund (fiscal year end
of October 31) reflect the historical financial highlights of the Winslow Fund
(fiscal year end of June 30) prior to the reorganization.

On June 29, 2005, the Fund acquired substantially all the net assets of the
MainStay Blue Chip Growth Fund, a series of the Trust, pursuant to an Agreement
and Plan of Reorganization approved by the shareholders on June 27, 2005. The
acquisition was accomplished by a transfer of all the assets and liabilities of
the MainStay Blue Chip Growth Fund (valued at $234,008,138), to the Fund.
Following the transfer, 45,899,942 shares of the Fund were distributed to
shareholders in liquidation of the MainStay Blue Chip Growth Fund in a tax free
exchange for 24,366,396 shares of the MainStay Blue Chip Growth Fund. The
reorganization qualified as a tax-free reorganization for federal income tax
purposes with no gain or loss recognized by the portfolios or their
shareholders. The MainStay Blue Chip Growth Fund's net assets at the date of
acquisition, including $15,306,040 and ($1,310,067) of unrealized appreciation
(depreciation), respectively, ($168,915,585) of accumulated net realized loss
and ($1,052,103) of undistributed net investment loss and ($846,002) of
liabilities were combined with those of the MainStay Large Cap Growth Fund. The
Fund constitutes the surviving entity for financial reporting purposes;
therefore it is deemed the "accounting survivor" for the merger. Effective June
29, 2005, the Fund's operations are combined with that of the Mainstay Blue Chip
Growth Fund in the accompanying Statement of Operations, Statements of Changes
in Net Assets, and Financial Highlights.

The Fund currently offers six classes of shares, Class A, Class B, Class C
shares, Class I shares, Class R1 shares and Class R2 shares, whose distribution
commenced on March 31, 2005. Class A shares are offered at net asset value per
share plus an initial sales charge. No sales charge applies on investments of $1
million or more (and certain other qualified purchases) in Class A shares, but a
contingent deferred sales charge is imposed on certain redemptions of such
shares within one year of the date of purchase. Class B shares and Class C
shares are offered without an initial sales charge, although a declining
contingent deferred sales charge may be imposed on redemptions made within six
years of purchase of Class B shares and within one year of purchase of Class C
shares. Class I, Class R1 and Class R2 shares are not subject to sales charge.
The six classes of shares bear the same voting (except for issues that relate
solely to one class), dividend, liquidation and other rights and conditions
except that Class B shares and Class C shares are subject to higher distribution
fee rates than Class A shares and Class R2 shares under a distribution plan
pursuant to Rule 12b-1 under the 1940 Act. Class I shares and Class R1 shares
are not subject to a distribution or service fee. Class R1 and Class R2 shares
are authorized to pay to New York Life Investment Management LLC, its
affiliates, or independent third-party service providers, as compensation for
services rendered to shareholders of Class R1 or Class R2 shares, a shareholder
service fee.

The Fund's investment objective is to seek long-term growth of capital.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

The Fund prepares its financial statements in accordance with accounting
principles generally accepted in the United States of America and follows the
significant accounting policies described below.

(A) SECURITIES VALUATION.  Equity securities are valued at the latest quoted
sales prices as of the close of trading on the New York Stock Exchange
(generally 4:00 p.m. Eastern time) on the valuation date; such securities not
traded on the valuation date are valued at the mean of the latest quoted bid and
asked prices. Prices normally are taken from the principal market in which each
security trades. Temporary cash investments acquired over 60 days to maturity
are valued using the latest bid prices or using valuations based on a matrix
system (which considers such factors as security prices, yields, maturities, and
ratings), both as furnished by independent pricing services. Other temporary
cash investments are valued at amortized cost, which approximates market value.
Securities for which market quotations are not readily available are valued by
methods deemed in good faith by Board of Trustees to

 18   MainStay Large Cap Growth Fund


represent fair value. Reasons for which securities may be valued in this manner
include, but are not limited to, trading for a security has been halted or
suspended, a security has been de-listed from a national exchange, or trading on
a security's principal market is temporarily closed at a time when under normal
conditions it would be open. The Fund did not hold securities at October 31,
2005, that were valued in such manner.

(B) SECURITIES LENDING.  The Fund may lend its securities to broker-dealers and
financial institutions. The loans are collateralized by cash or securities at
least equal at all times to the market value of the securities loaned. The Fund
may bear the risk of delay in recovery of, or loss of rights in, the securities
loaned should the borrower of the securities experience financial difficulty.
The Fund receives compensation for lending its securities in the form of fees or
it retains a portion of interest on the investment of any cash received as
collateral. The Fund also continues to receive interest and dividends on the
securities loaned and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan will be for the account of the
Fund. (see Note 7.)

(C) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to the shareholders of the Fund within the
allowable time limits. Therefore, no federal income or excise tax provision is
required.

Investment income received by the Fund from foreign sources may be subject to
foreign income taxes. These foreign income taxes are withheld at the source.

(D) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions are
recorded on the ex-dividend date. The Fund intends to declare and pay dividends
quarterly and capital gain distributions, if any, annually. Income dividends and
capital gain distributions are determined in accordance with federal income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These "book/tax differences" are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax basis treatment; temporary differences do not require
reclassification.

The following table discloses the current year reclassifications between net
investment loss, accumulated net realized loss on investments and additional
paid-in-capital arising from permanent differences; net assets at October 31,
2005, are not affected.

<Table>
<Caption>
    NET       ACCUMULATED NET   ADDITIONAL
 INVESTMENT    REALIZED LOSS      PAID-IN
    LOSS      ON INVESTMENTS      CAPITAL
                          
 $1,086,262      $(35,290)      $(1,050,972)
 ------------------------------------------
</Table>

The reclassification for the Fund is due to the reclassification of net
operating losses that cannot be utilized for tax purposes.

(E) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned.
Discounts and premiums on securities, other than short-term securities,
purchased for the Fund are accreted and amortized, respectively, on the constant
yield method over the life of the respective securities or, in the case of a
callable security, over the period to the first date of call. Discounts and
premiums on short-term securities are accreted and amortized, respectively, on
the straight line method.

Investment income and realized and unrealized gains and losses on investments of
the Fund are allocated to separate classes of shares based upon their relative
net assets on the date the income is earned or realized and unrealized gains and
losses are incurred.

(F) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and expenses incurred under the distribution
plans) are allocated to separate classes of shares based upon their relative net
asset value on the date the expenses are incurred. The expenses borne by the
Fund, including those of related parties to the Fund, are shown in the Statement
of Operations.

(G) USE OF ESTIMATES.  The preparation of financial statements in accordance
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(H) INDEMNIFICATIONS.  In the normal course of business the Fund enters into
contracts with third party service providers that contain a variety of
representations and warranties and which provide general indemnifications. The
Fund's maximum exposure under these arrangements is unknown, as this would

risk of loss in connection with these potential indemnification obligations is
remote; however, there can be no assurance that material liabilities related to
such obligations will not arise in the future that could adversely impact the
Fund.

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("NYLIM" or
the "Manager"), an indirect wholly-owned subsidiary of New York Life Insurance
Company ("New York Life"), serves as the Fund's manager. The Manager provides
offices, conducts clerical, recordkeeping and bookkeeping services, and keeps
the financial and accounting records required for the Fund. The Manager also
pays the salaries and expenses of all personnel affiliated with the Fund and all
the operational expenses that are not the responsibility of the Fund. Winslow
Capital Management, Inc. (the "Subadvisor"), is responsible for the day-to-day
portfolio management of the Fund.

Prior to March 31, 2005, the Fund was advised by Fiduciary Management, Inc.
("FMI") and subadvised by the subadvisor.

The Trust, on behalf of the Fund, pays the Manager a monthly fee for services
performed and the facilities furnished at an annual percentage of the Fund's
average daily net assets as follows: 0.80% on assets up to $250 million, 0.75%
on assets from $250 million up to $500 million, 0.725% on assets from $500
million up to $750 million, 0.70% on assets from $750 million up to $2.0
billion, 0.65% on assets from $2.0 billion up to $3.0 billion, and 0.60% on
assets in excess of $3.0 billion. The Manager has also voluntarily agreed to
waive a portion of its management fee so that the management fee does not exceed
0.75% on assets up to $250 million. Effective August 1, 2005, the Manager has
entered into a written expense limitation agreement, under which the Manager has
agreed to reimburse the expenses of the Fund so that the total operating
expenses (excluding taxes, interest, litigation, extraordinary expenses, and
brokerage and other transaction expenses relating to the purchase or sale of
portfolio investments) do not exceed, on an annualized basis, 1.40% of the
average daily net assets of the Class A shares. An equivalent reimbursement, in
an equal amount of basis points, will be applied to the other share classes. The
Manager, within three years of incurring such expenses, may recoup the amount of
any management fee waiver or expense reimbursement from the Fund pursuant to
this agreement if such recoupment does not cause the Fund to exceed the expense
limitations. This expense limitation may be modified or terminated only with the
approval of the Board of Trustees. Prior to August 1, 2005, the Manager
voluntarily agreed to waive other fees and/or reimburse the Fund so that total
annual fund operating expenses would not exceed on an annualized basis 1.40% of
the average daily net assets of the Class A shares, and such that there would be
an equivalent reduction for the other classes of shares. For the period ended
October 31, 2005, the manager earned from the Fund $838,898 and waived its fee
and/or reimbursement expense in the amount of $397,089. For the period from
March 31, 2005 through June 30, 2005, the Manager earned from the Fund $31,005
and waived its fee and/or reimbursed expenses in the amount of $82,942.

Prior to March 31, 2005, the Winslow Fund paid FMI a monthly fee for services
performed at an annual percentage of 1% of the Fund's average daily net assets.
FMI was contractually obligated to reimburse the Winslow Fund for expenses over
2.00% of the daily net assets of the Winslow Fund. In addition to the
reimbursement required under the management agreement, FMI voluntarily
reimbursed the Winslow Fund for expenses over 1.30% of the daily net assets of
the Fund. For the period from July 1, 2004 through March 31, 2005, FMI earned
from the Fund $37,572 and waived its fee and/or reimbursement expense in the
amount of $53,796.

Pursuant to the terms of a Sub-Advisory Agreement between NYLIM and the
Subadvisor, dated April 1, 2005, the Manager paid the Subadvisor a monthly fee
at an annual rate of the average daily net assets of all Winslow-serviced
investment company assets managed by NYLIM, including the Fund as follows: 0.40%
up to $250 million, 0.35% on assets from $250 million up to $500 million, 0.30%
on assets from $500 million up to $750 million, 0.25% on assets from $750
million up to $1.0 billion, and 0.20% on assets in excess of $1.0 billion.

Prior to March 31, 2005, Winslow Capital Management, Inc., ("Winslow") served as
sub-advisor to the Winslow Fund. FMI paid Winslow a fee of 0.75% of the Winslow
Fund's management fee.

In addition, prior to March 31, 2005, pursuant to the terms of an administrative
agreement with FMI, the Winslow Fund paid FMI a monthly administrative fee at
the annual rate of 0.20% on the first $25.0 million of the Winslow Fund's daily
net assets, 0.10% on the next $20.0 million of the Winslow Fund's daily net
assets, and 0.05% over $45.0 million of the Winslow Fund's daily net assets,
subject to a fiscal year minimum of $20,000. FMI voluntarily waived this
minimum. For the year ended June 30, 2005, Administration fees of $7,514 are
included in Management Fees in the accompanying Statement of Operations.

(B) DISTRIBUTION AND SERVICE FEES  The Trust, on behalf of the Fund, has a
Distribution Agreement with NYLIFE Distributors LLC ("the Distributor"), an
indirect wholly-owned subsidiary of New York Life. Effective March 31, 2005, the
Fund, with respect to each class of shares other than Class I shares, has
adopted distribution

 20   MainStay Large Cap Growth Fund


plans (the "Plans") in accordance with the provisions of Rule 12b-1 under the
1940 Act. Pursuant to the Class A Plan, the Distributor receives a monthly fee
from the Fund at an annual rate of 0.25% of the average daily net assets of the
Fund's Class A shares, which is an expense of the Class A shares of the Fund for
distribution or service activities as designated by the Distributor. Pursuant to
the Class B and Class C Plans, the Fund pays the Distributor a monthly fee,
which is an expense of the Class B and Class C shares of the Fund, at the annual
rate of 0.75% of the average daily net assets of the Fund's Class B and Class C
shares. The Distribution Plans provide that the Class B, Class C and Class R2
shares of the Fund also incur a service fee at the annual rate of 0.25% of the
average daily net asset value of the Class B or Class C shares of the Fund.
Class I shares and Class R1 shares are not subject to a distribution or service
fee.

The Plans provide that the distribution and service fees are payable to the
Distributor regardless of the amounts actually expended by the Distributor for
distribution of the Fund's shares and service activities.

The Fund has adopted a shareholder services plan with respect to Class R1 and R2
shares. Under the terms of this plan, Class R1 and Class R2 shares are
authorized to pay to NYLIM, its affiliates, or independent third-party
providers, as compensation for services rendered, a shareholder service fee at
the rate of 0.10% of the average daily net assets of the Fund's Class R1 and R2
shares.

Prior to March 31, 2005, the Winslow Fund had entered into a Distribution Plan
pursuant to Rule 12b-1 under the Investment Company Act of 1940. The Plan
provided that the Fund may incur certain costs which may not exceed the lesser
of a monthly amount equal to 0.25% of the Fund's daily net assets or the actual
distribution cost incurred during the year.

(C) SALES CHARGES.  The Fund was advised by the Distributor that the amount of
sales charges retained on sales of Class A shares was $14,810 for the period
ended October 31, 2005. The Fund was also advised that the Distributor retained
contingent deferred sales charges on redemptions of Class A, Class B and Class C
shares of $1,334, $89,100 and $741, respectively, for the period ended October
31, 2005.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  Effective
March 31, 2005, NYLIM Service Company LLC ("NYLIM Service"), an affiliate of
NYLIM, is the Fund's transfer, dividend disbursing and shareholder servicing
agent. NYLIM Service has entered into an agreement with Boston Financial Data
Services ("BFDS") pursuant to which BFDS will perform certain of the services
for which NYLIM Service is responsible. Transfer agent expenses paid to NYLIM
for the period ended October 31, 2005 and the period from March 31, 2005 through
June 30, 2005 were $463,984 and $4,189, respectively.

Prior to March 31, 2005, Transfer Agent expenses paid to U.S. Bancorp Fund
Services, LLC for the period July 1, 2004 through March 31, 2005 were $11,600.

(E) NON-INTERESTED TRUSTEES FEES.  Non-Interested Trustees are paid an annual
retainer fee of $45,000, $2,000 for each Board meeting, $1,000 for each
Committee meeting and $500 for each Valuation Subcommittee telephonic meeting
attended plus reimbursement for travel and out-of-pocket expenses. The Lead
Non-Interested Trustee is also paid an annual retainer fee of $20,000. The Audit
and Compliance Committee Chairman receives an additional $2,000 for each meeting
of the Audit and Compliance Committee attended and the Chairpersons of the
Brokerage and Expense Committee, Operations Committee and Performance Committee
each receive an additional $1,000 for each meeting of the Brokerage and Expense
Committee, Operations Committee and Performance Committee attended,
respectively. In addition, each Non-Interested Trustee is paid $1,000 for
attending meetings of the Non-Interested Trustees held in advance of or in
connection with Board/Committee meetings. The Trust allocates trustees fees in
proportion to the net assets of the respective Funds. Thus, effective March 31,
2005, the Fund only pays a portion of the fees identified above.

(F) OTHER.  Pursuant to the Management Agreement, fees for the cost of legal
services, included in Professional fees as shown on the Statement of Operations,
provided to the Fund by the Office of the General Counsel of NYLIM amounted to
$6,032 for the period ended October 31, 2005. Legal fees paid for the period
March 31, 2005 through June 30, 2005 and the period July 1, 2004 through March
31, 2005 were $5,814 and $15,881, respectively.

Effective March 31, 2005, the Fund pays the Manager a monthly fee for certain
pricing and recordkeeping services provided under the Accounting Agreement at
the annual rate of 1/20 of 1% for the first $20 million of average monthly net
assets, 1/30 of 1% of the next $80 million of average monthly net assets and
1/100 of 1% of any amount in excess of $100 million of average monthly net
assets. Fees for these services provided to the Fund by the Manager amounted to
$19,610 for the period ended October, 2005 and $3,033 for the period from March
31, 2005 through June 30, 2005.

NOTE 4--CUSTODIAN:

Investors Bank & Trust Company is the custodian of cash and securities of the
Fund. Custodial fees are charged to the Fund based on the market value of
securities in the Fund and the number of certain cash transactions incurred by
the Fund. Formerly, The Bank of New York acted as custodian for the Fund.

of $168,901,948 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

NOTE 10--OTHER MATTERS:

NYLIM and mutual funds that NYLIM advises have received requests for information
from various government authorities and regulatory bodies regarding market
timing, late trading, operations, fees, expenses, and other matters. NYLIM and
the funds it advises have cooperated fully and completed responding to these
requests. As previously reported in response to those requests for information
and, as noted in the notes to the year-end 2004 financial statements of each
fund of the Trust, NYLIM had been a party to arrangements with certain
registered representatives of broker-dealers relating to the level of trading by
clients of those registered representatives in shares of certain funds of the
Trust. All such arrangements were terminated by the fourth quarter of 2003.
NYLIM and the Trustees of the Trust have reviewed the possible dilutive effects
that transactions under those arrangements and certain other levels of trading
by fund shareholders over the period from 1999 to 2003 may have had on the
funds. As a result of this review, in December 2005, NYLIM made payments
totaling $5.9 million to nine MainStay funds. No payment was made with respect
to the MainStay Large Cap Growth Fund. NYLIM has also agreed to reimburse or pay
all expenses relating to the Board of Trustees' review of this matter and has
paid substantially all of the costs associated with the other regulatory matters
described in this note.

In a separate matter, the SEC has raised concerns relating to a guarantee
provided to shareholders of the MainStay Equity Index Fund and the fees and
expenses of that fund as well as the related guarantee disclosure to fund
shareholders. Discussions have been held with the SEC concerning a possible
resolution of this matter. There can be no assurance of the outcome of these
efforts.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Trustees and Shareholders of
The MainStay Funds:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of the MainStay Large Cap Growth Fund (the
"Fund"), one of the funds constituting The MainStay Funds, as of October 31,
2005, and the related statements of operations and changes in net assets and the
financial highlights for the four-month period ended October 31, 2005 and the
year ended June 30, 2005. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits. The statement of changes in net assets for the year ended June
30, 2004, and the financial highlights for the years presented through June 30,
2004, were audited by other auditors, whose report dated August 4, 2004,
expressed an unqualified opinion thereon.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
MainStay Large Cap Growth Fund of The MainStay Funds as of October 31, 2005, and
the results of its operations, the changes in its net assets and financial
highlights for the four-month period ended October 31, 2005 and the year ended
June 30, 2005, in conformity with U.S. generally accepted accounting principles.

BOARD CONSIDERATION AND APPROVAL OF MANAGEMENT AND SUBADVISORY AGREEMENTS

In connection with the renewal of the Fund's Management Agreement and
Subadvisory Agreement, the Board of Trustees requested and received from the
Manager and Subadvisor, and reviewed, a wide variety of information. The
Trustees also requested and received information from outside data providers and
information and analysis from a third party consultant. The Trustees considered
various industry and regulatory trends in their deliberations. In considering
approval of these Agreements, and in evaluating the fairness of the compensation
to be paid by the Fund, the Trustees met a number of times as a full Board and
in executive sessions of only the Non-Interested Trustees to discuss the Board's
consideration of the approval of the Agreements, and took into account a number
of factors, as discussed below.

The Trustees considered the nature, extent and quality of the services to be
provided by the Manager and the Subadvisor. The Trustees reviewed the services
that the Manager has provided historically to the Fund, and also generally to
other series of the Trust, and the services provided over a shorter term by the
Subadvisor to the Fund. The Manager's services to the Trust have included
investment management services, including the selection and supervision of
portfolio managers or subadvisers, and administrative services, including
interacting with other service providers to the Trust, maintaining certain Fund
records, providing office space, performing clerical and bookkeeping services
for the Fund, preparing Fund filings, and other administrative services. The
Subadvisor's services have included, among other things, providing the day-to-
day management of the portfolio, providing reports to the Manager, and reviewing
certain aspects of Fund filings. The Trustees considered, among other things,
the Manager's and Subadvisor's management, personnel, resources, operations and
portfolio management capabilities. In considering the Manager's and Subadvisor's
practices relating to best execution of portfolio trades, the Board reviewed
reports of the Fund's Brokerage Committee including with respect to analysis
prepared by Plexus Group. The Trustees noted that the Fund's assets represented
a significant portion of the Subadvisor's assets under management. The Trustees
considered the Manager's supervision of the Fund's service providers and its
attention to the compliance program of the Trust, the Manager, the Subadvisor
and certain other service providers, as well as the Subadvisor's attention to
its compliance program. The Trustees noted the generally favorable conclusions
of financial services research firm DALBAR Inc. of the services, investor
complaint levels, and communications that NYLIM Service Company LLC ("NYLIM
Service"), an affiliate of the Manager, has provided to Trust shareholders. A
majority of the Trustees, including a majority of the Non-Interested Trustees,
concluded that, overall, the nature, extent and quality of the services expected
to be provided by the Manager and Subadvisor were such that, in the context of
the Board's overall review of various factors, the Agreements should be renewed.

The Trustees reviewed the investment performance of the Fund over various time
periods and compared that performance to that of multiple groups of funds the
Trustees concluded were comparable to the Fund. In conducting this review, the
Trustees relied in part on information provided by outside data providers and
were assisted in their analysis by a third party consultant. The Board's
decision took account of, among other things, the Fund's favorable recent
performance, and noted the Subadvisor's favorable performance as manager of FMI
Winslow Growth Fund before it was reorganized with and into the Fund.

The Trustees considered the cost to the Manager of the Agreements and the
profitability to the Manager and its affiliates of the relationship with the
Fund over various time periods; in assessing the cost the Trustees used the
services of a third party consultant, which, among other things, reviewed
allocations of various costs made by the Manager among the Fund and other
clients of the Manager. The information reviewed by the Board included
information about the general costs to the Manager and its affiliates of
subsidizing expenses for some smaller series of the Trust pending the growth of
their assets. The Trustees noted the Manager's agreement to limit the Fund's net
expenses to a certain level with respect to the Fund, with the expectation that
the Manager intended, over time, to implement measures designed to reduce the
Trust's transfer agency fees. The Trustees considered certain benefits expected
for, and risks borne by, the Manager and its affiliates, including benefits from
soft dollar arrangements. The Trustees considered the services provided to the
Fund by affiliates of the Manager, NYLIFE Distributors and NYLIM Service, under
other agreements, and the benefits to the Manager and its affiliates from those
relationships. The information provided to the Trustees indicated that the
profitability to the Manager and its affiliates arising directly from those
other agreements was not excessive. The Trustees acknowledged certain benefits
to the reputation of the Manager and its affiliates, as well to that of the
Trust, from their association with each other.

The Trustees discussed the extent to which economies of scale were projected by
the Manager to be realized as the Fund grows, or as the Trust grows overall,
noting in particular the Manager's plans for marketing and distributing shares
of various series of the Trust. They noted the Manager's willingness to
implement contractual breakpoints, and that the contractual breakpoints in place
for the management fee were intended to provide that the Fund's shareholders
would share in benefits from economies of scale arising from the growth of Fund
assets. The Trustees noted that the Fund's contractual management fee

 28   MainStay Large Cap Growth Fund


had been reduced in accordance with the terms of the breakpoint schedule
applicable to the Fund. Acknowledging the difficulty of forecasting economies of
scale, the Trustees generally expressed an intention to monitor the Manager's
profitability and consider the application of fee breakpoints or other
appropriate measures as the Board may determine from time to time. The Trustees
reviewed historical information about changes in the Fund's expense and asset
levels over time, as well as information about certain Fund expenses that would
remain fixed even as Fund assets increase and, therefore, provide the Fund with
benefits from economies of scale as the Fund grows. The Trustees noted that, to
the extent the Fund's gross expenses currently are higher than its net expenses,
economies of scale achieved through an increase in the Fund's assets might not
directly benefit the Fund through lower net expenses. The Trustees considered
various information about transfer agency expenses, including information
showing that transfer agency fees of a significant number of series of the Trust
(although not every such series or with respect to every share class of each
series) tended to be high, when aggregated and expressed as a percentage of the
assets of certain series, compared to the mutual fund industry average according
to certain studies reviewed by the Board and, therefore, adversely affected
gross expense ratios. The Board received information about potential effects on
the Manager were it to subsidize certain portions of the Trust's transfer agency
fees. The Trustees noted that a significant number of shareholders of the
Trust's series had small amounts invested in the series, and have considered
measures intended to increase average shareholder account size and/or otherwise
reduce the Trust's transfer agency fees and expenses, including steps that the
Manager has taken to encourage shareholders to consolidate or close small
accounts.

The Trustees considered services provided by other advisers to funds having
investment objectives and policies similar to those of the Fund. The Board
received, among other things, comparative data with respect to various types of
fund expenses that third party data providers compiled using objective
methodologies and provided for use by the Trustees. The Trustees received
information regarding the combined advisory and administrative fees paid by
other clients of the Manager, including other registered funds and separate
institutional accounts, that had investment objectives similar to that of the
Fund. The Trustees took into account information provided by the Manager about
the relative scope of services provided to the Fund and to those accounts or
explanations about the accounts' histories. In considering the extent of the
fees received by the Manager for providing services to the Fund, the Trustees
evaluated factors such as the fees and expenses borne by other registered funds
in the market pursuing strategies generally similar to those followed by the
Fund. The Trustees considered the Fund's current and proposed contractual and
net management fees, its anticipated gross and net expense ratios, and various
components of that expense ratio, in comparison to other funds in comparison
groupings prepared by outside data providers using objective methodologies.

The Trustees acknowledged the historical relationship between the Manager and
the Trust and the likely difficulties in implementing an alternative to the
investment management arrangement between them. The Trustees also took account
of the results of their various discussions with the Manager concerning the
levels of the Fund's contractual and net management fees, the Fund's anticipated
net expense level, and the level of the subadvisory fee.

The materials and other information described above were considered by the
Trustees throughout the past year during in-person and telephonic meetings with
personnel of the Manager, fund counsel, third party consultants, and independent
counsel, and also were considered by the Non-Interested Trustees meeting
separately and with independent counsel. The Trustees considered these factors
in light of the recent reorganization of FMI Winslow Growth Fund, an
unaffiliated fund, with and into the Fund and the separate reorganization of the
Fund with the Blue Chip Growth Fund, another series of the Trust. The Trustees
did not identify any particular information or any single factor that was
controlling, or the particular weight any Trustee placed on any one factor for
purposes of determining whether to vote in approval of the Agreements. The
summary set out above describes the most important factors, but not all of the
matters considered by the Trustees in coming to their decision regarding the
Agreements. On the basis of their review, a majority of the Trustees and a
majority of the Non-Interested Trustees concluded that each factor they
considered, in the context of all of the other factors they considered, favored
renewal of the Agreements, and it was the judgment of a majority of the Trustees
and a majority of the Non-Interested Trustees that approval of these Agreements
was in the best interests of the Fund and its shareholders.

ITEM 2. CODE OF ETHICS.

As of the end of the period covered by this report, the Registrant has adopted a
code of ethics (the "Code") that applies to the Registrant's principal executive
officer ("PEO") and principal financial officer ("PFO"). The Code was amended
during the period covered by the report to designate new individuals as the PEO
and PFO; a copy of the amended Code is filed herewith. The Registrant did not
grant any waivers, including implicit waivers, from any provisions of the Code
to the PEO or PFO during the period covered by this report.

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The Board of Trustees has determined that its Audit and Compliance Committee
does not currently have any member that qualifies as an "audit committee
financial expert" as defined under rules adopted by the Securities and Exchange
Commission. In accordance the authority granted under the Registrant's Audit and
Compliance Committee Charter, the Audit and Compliance Committee has retained a
third party consultant to provide the Committee and the Registrant with the
financial expertise, knowledge and skills similar to those of an audit committee
financial expert.

year ended October 31, 2004.

(e) Pre-Approval Policies and Procedures

     (1) The Registrant's Audit and Compliance Committee has adopted
     pre-approval policies and procedures (the "Procedures") to govern the
     Committee's pre-approval of (i) all audit services and permissible
     non-audit services to be provided to the Registrant by its independent
     accountant, and (ii) all permissible non-audit services to be provided by
     such independent accountant to the Registrant's investment adviser and to
     any entity controlling, controlled by or under common control with the
     investment adviser that provides ongoing services to the Registrant
     (collectively, the "Service Affiliates") if the services directly relate to
     the Registrant's operations and financial reporting. In accordance with the
     Procedures, the Audit and Compliance Committee is responsible for the
     engagement of the independent accountant to certify the Registrant's
     financial statements for each fiscal year. With respect to the pre-approval
     of non-audit services provided to the Registrant and its Service
     Affiliates, the Procedures provide that the Audit and Compliance Committee
     may annually pre-approve a list of the types of services that may be
     provided to the Registrant or its Service Affiliates, or the Audit and
     Compliance Committee may pre-approve such services on a project-by-project
     basis as they arise. Unless a type of service has received general
     pre-approval, it will require specific pre-approval by the Audit and
     Compliance Committee if it is to be provided by the independent accountant.
     The Procedures also permit the Audit and Compliance Committee to delegate
     authority to one or more of its members to pre-approve any proposed
     non-audit services that have not been previously pre-approved by the Audit
     and Compliance Committee, subject to the ratification by the full Audit and
     Compliance Committee no later than its next scheduled meeting. To date, the
     Audit and Compliance Committee has not delegated such authority.


                                        3



     (2) With respect to the services described in paragraphs (b) through (d) of
     this Item 4, no amount was approved by the Audit and Compliance Committee
     pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) There were no hours expended on KPMG's engagement to audit the Registrant's
financial statements for the most recent fiscal year attributable to work
performed by persons other than KPMG's full-time, permanent employees.

(g) All non-audit fees billed by KPMG for services rendered to the Registrant
for the fiscal years ended October 31, 2005 and October 31, 2004 are disclosed
in 4(b)-(d) above.

The aggregate non-audit fees billed by KPMG for services rendered to the
Registrant's investment adviser (not including any sub-adviser whose role is
primarily portfolio management and is subcontracted with or overseen by another
investment adviser), and any entity controlling, controlled by, or under common
control with the adviser that provides ongoing services to the Registrant were
approximately: (i) $15,000, for the year ended October 31, 2005, and (ii) $0,
for the fiscal year ended October 31, 2004.

(h) The Registrant's Audit and Compliance Committee has determined that the
non-audit services rendered by KPMG for the fiscal year ended October 31, 2005
to the Registrant's investment adviser and any entity controlling, controlled
by, or under common control with the Registrant's investment adviser that
provides ongoing services to the Registrant that were not required to be
pre-approved by the Audit and Compliance Committee because they did not relate
directly to the operations and financial reporting of the registrant were
compatible with maintaining the respective independence of KPMG during the
relevant time period.

management, including the Registrant's principal executive officer and principal
financial officer, as appropriate to allow timely decisions regarding required
disclosure.

reporting (as defined in Rule 30a-3(d)) under the Investment Company Act of 1940

affect, the Registrant's internal control over financial reporting.
