        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

        Unaudited - April 30, 2010



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during the reporting period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six-month reporting period, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the reporting period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


Throughout the six-month reporting period, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the six months ended April 30, 2010. Of course, past performance
is no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

1. 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 maximum applicable sales charges explained in this paragraph,
   change in share price, and reinvestment of dividend and capital gain
   distributions. The graphs assume an initial investment of $25,000 for Class A
   shares and $10,000 for all other classes and reflect the deduction of all
   sales charges that would have applied for the period of investment. Class A
   shares generally have a $25,000 minimum initial investment with no minimum
   subsequent purchase amount. For investors that, in the aggregate, have assets
   of $100,000 or more invested in any share classes of any of the MainStay
   Funds, the minimum initial investment is $15,000. Investor Class shares and
   Class A shares are sold with a maximum initial sales charge of 5.50% and an
   annual 12b-1 fee of 0.25%. Class B shares are sold with no initial sales
   charge, are subject to a contingent deferred sales charge ("CDSC") of up to
   5.00% 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 1.00% 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 or individual 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. For information on current fee waivers and/or expense limitations,
   please refer to the notes to the financial statements. Effective October 30,

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY U.S. SMALL CAP FUND
(UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, 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, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). 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 November 1, 2009, to April 30, 2010.

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 April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

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

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

1. Expenses are equal to the Fund's annualized expense ratio of each class
   (1.63% for Investor Class, 1.49% for Class A, 2.38% for Class B and Class C
   and 1.17% for Class I) multiplied by the average account value over the
   period, divided by 365 and multiplied by 181 (to reflect the one-half year
   period). The table above represents the actual expenses incurred during the
   one-half year period.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS

QUESTIONS ANSWERED BY PORTFOLIO MANAGERS DAVID PEARL, WILLIAM PRIEST, CFA, AND
MICHAEL WELHOELTER, CFA, OF EPOCH INVESTMENT PARTNERS, INC. (EPOCH), THE FUND'S
SUBADVISOR.

HOW DID MAINSTAY U.S. SMALL CAP FUND PERFORM RELATIVE TO ITS PEERS AND ITS
BENCHMARK DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay U.S. Small Cap Fund returned 19.41% for
Investor Class shares, 19.50% for Class A shares, 18.97% for Class B shares and
18.98% for Class C shares for the six months ended April 30, 2010. Over the same
period, the Fund's Class I shares returned 19.73%. All share classes
underperformed the 25.42% return of the average Lipper(1) small-cap core fund,
the 27.58% return of the Russell 2500(TM) Index(2) and the 30.66% return of the
Russell 2000(R) Value Index(3) for the six months ended April 30, 2010. The
Russell 2500(TM) Index is the Fund's broad-based securities-market index. See
pages 5 and 6 for Fund returns with sales charges.

WHAT MAJOR FACTORS INFLUENCED THE FUND'S RELATIVE PERFORMANCE DURING THE
REPORTING PERIOD?

Throughout the reporting period, we stayed true to our philosophy and process.
The Fund focused on quality companies that were generating free cash flow and
that were run by management teams with a demonstrated ability to effectively
allocate that cash flow to increase shareholder returns. While the Fund
generated robust absolute gains during the reporting period, investors tended to
prefer lower-quality small-cap companies over stocks that fit the Fund's more
conservative, cash-flow-oriented approach. In light of these market dynamics, we
were not surprised that the Fund lagged the Russell 2500(TM) Index during the
reporting period.

DURING THE REPORTING PERIOD, WHICH SECTORS MADE THE STRONGEST CONTRIBUTIONS TO
THE FUND'S RELATIVE PERFORMANCE AND WHICH SECTORS MADE THE WEAKEST
CONTRIBUTIONS?

Relative to the Russell 2500(TM) Index, the strongest-contributing sectors to
the Fund's performance were consumer staples, industrials and utilities. Strong
stock selection across all three sectors helped relative performance, as did the
Fund's modest underweight position in consumer staples. While the Fund shifted
during the reporting period from an underweight position to a significantly
overweight position in industrials, sector allocation within this sector still
detracted modestly from the Fund's relative performance. The Fund's overweight
position in utilities, which was reduced during the reporting period, also hurt
the Fund's results relative to the Russell 2500(TM) Index.

While all sectors within the Russell 2500(TM) Index generated strong double-
digit absolute returns during the reporting period, the sectors that detracted
the most from the Fund's performance relative to the benchmark were financials
and consumer discretionary. Stock selection in both sectors was weak. During the
reporting period, the Fund reduced its exposure to financials from an overweight
to an underweight position relative to the Russell 2500(TM) Index, but the
allocation to the financials sector still detracted from the Fund's relative
performance. In light of our belief that many small-cap financial companies--and
small-cap banks in particular--faced continuing credit issues, the Fund focused
on companies with transparent and well-capitalized loan portfolios and on asset
managers and reinsurance companies. The Fund's small cash position detracted, as
the Fund was not fully invested in equities during the significant market rally.

WHICH INDIVIDUAL STOCKS WERE THE STRONGEST CONTRIBUTORS TO THE FUND'S ABSOLUTE
PERFORMANCE DURING THE REPORTING PERIOD AND WHICH STOCKS DETRACTED?

The stocks that made the strongest contributions to the Fund's absolute
performance during the reporting period were networking systems maker 3Com
(which was acquired during the reporting period by Hewlett-Packard), mutual fund
company Waddell & Reed Financial and specialty pharmaceutical company Alkeremes.

Among the greatest detractors from the Fund's absolute performance were marine
contractor for the offshore oil & gas industry Cal Dive, enterprise data storage
solutions provider STEC and video game retailer GameStop. We chose to sell the
Fund's position in STEC during the reporting period. We increased the Fund's
exposure to GameStop on the belief that we were at the beginning stages of
seeing a new round of computer games come to the market.

DID THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES DURING THE REPORTING
PERIOD?

We selectively added to the Fund's industrial exposure during the reporting
period with the purchase of a number of new companies, including metal products
fabricator Mueller Industries and building and construction products maker
Simpson Manufacturing.

We believe that both of these companies may benefit from a rebound in the
housing market, as should our purchase of furnishings components manufacturer
Leggett & Platt in the consumer discretionary sector. In financials, we
established a new Fund position in Kansas lender Capitol Federal Financial.

We sold the Fund's position in 3Com when the company was acquired by computer
maker Hewlett-Packard. In financials, we sold a number of Fund positions,
including Bank Mutual and Sterling Bancshares.

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

During the reporting period, the Fund increased its weightings in the
industrials and consumer discretionary sectors. In both cases, the Fund moved
from an underweight to an overweight position relative to the Russell 2500(TM)
Index. We reduced the Fund's exposure to financials, moving to an underweight
position relative to the benchmark.

HOW WAS THE FUND POSITIONED AT THE END OF APRIL 2010?

As of April 30, 2010, the Fund's most substantially overweight sectors relative
to the Russell 2500(TM) Index were industrials and information technology. On
the same date, the Fund's most substantially underweight sector relative to the
Russell 2500(TM) Index was financials.

20    MainStay U.S. Small Cap Fund  The notes to the financial statements are an
integral part of, and should be read in conjunction with, the financial
statements.



NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

Eclipse Funds (the "Trust") was organized on July 30, 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 is comprised of two funds (collectively referred to as the "Funds"). These
financial statements and notes relate only to the MainStay U.S. Small Cap Fund
(the "Fund"), a diversified fund.

The Fund currently offers five classes of shares. Class I shares commenced
operations on January 12, 1987. Class A shares and Class B shares commenced
operations on January 2, 2004. Class C shares commenced operations on December
30, 2002. Investor Class shares commenced operations on February 28, 2008.
Investor Class and Class A shares are offered at net asset value ("NAV") per
share plus an initial sales charge. No sales charge applies on investments of $1
million or more (and certain other qualified purchases) in Investor Class and
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 at NAV without an initial sales charge,
although a declining contingent deferred sales charge may be imposed on
redemptions made within six years of purchase of Class B shares and a 1.00%
contingent deferred sales charge may be imposed on redemptions made within one
year of purchase of Class C shares. Class I shares are offered at NAV and are
not subject to a sales charge. Depending upon eligibility, Class B shares
convert to either Investor Class or Class A shares eight years after the date
they were purchased. Additionally, depending upon eligibility, Investor Class
shares may convert to Class A shares and Class A shares may convert to Investor
Class shares. The five classes of shares have the same voting (except for issues
that relate solely to one class), dividend, liquidation and other rights, and
the same terms and conditions, except that Class B and Class C shares are
subject to higher distribution and/or service fee rates than Investor Class and
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 and/or service fee.

The Fund's investment objective is to seek long-term capital appreciation by
investing primarily in securities of small-cap 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 ("GAAP") 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 regular trading on the New York Stock Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the Fund is open for
business ("valuation date"). Securities that are 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.
Futures contracts are valued at the last posted settlement price on the market
where such futures are primarily traded. Investments in other mutual funds are
valued at their NAVs as of the close of the New York Stock Exchange on the
valuation date.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at 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 the principal amount due at
maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the Fund's Manager or Subadvisor, as defined in Note 3(A),
reflect the security's market value; and (vi) a security where the trading on
that security's principal market is temporarily closed at a time when, under
normal conditions, it would be open. At April 30, 2010, the Fund did not hold
securities that were valued in such a manner.

"Fair value" is defined as the price that the Fund would receive upon selling an
investment in an orderly transaction to an independent buyer in the principal or
most advantageous market of the investment. Fair value measurements are
determined within a framework that has established a three-tier hierarchy which
maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are

                                                   mainstayinvestments.com    21



NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)


inputs that reflect the assumptions market participants would use in pricing the
asset or liability based on market data obtained from sources independent of the
reporting entity. Unobservable inputs are inputs that reflect the reporting
entity's own assumptions about the assumptions market participants would use in
pricing the asset or liability developed based on the information available in
the circumstances. The inputs or methodology used for valuing securities may not
be an indication of the risks associated with investing in those securities. The
three-tier hierarchy of inputs is summarized in the three broad Levels listed
below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
similar investments in active markets, interest rates and yield curves,
prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Fund's own assumptions
about the assumptions that market participants would use in determining the fair
value of investments)

The aggregate value by input level, as of April 30, 2010, for the Fund's
investments is included at the end of the Fund's Portfolio of Investments.

The valuation techniques used by the Fund to measure fair value during the six-
month period ended April 30, 2010 maximized the use of observable inputs and
minimized the use of unobservable inputs. The Fund may have utilized some of the
following fair value techniques: multi-dimensional relational pricing models,
option adjusted spread pricing and estimating the price that would have
prevailed in a liquid market for an international equity security given
information available at the time of evaluation, when there are significant
events after the close of local foreign markets. For the six-month period ended
April 30, 2010, there have been no changes to the fair value methodologies.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code")
applicable to regulated investment companies and to distribute all of the
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income tax provision is required.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the Fund's tax
positions taken on federal income tax returns for all open tax years (current
and prior three tax years), and has concluded that no provision for federal
income tax is required in the Fund's financial statements. The Fund's federal
and state income and federal excise tax returns for tax years for which the
applicable statutes of limitations have not expired are subject to examination
by the Internal Revenue Service and state departments of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund intends to declare and pay
dividends of net investment income and distributions of net realized capital and
currency gains, if any, annually. Unless the shareholder elects otherwise, all
dividends and distributions are reinvested in the same class of shares of the
Fund, at NAV. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method. Dividend income is
recognized on the ex-dividend date and interest income is accrued as earned
using the effective interest rate method. Discounts and premiums on short-term
investments 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 pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by the Fund, including
those of related parties to the Fund, are shown in the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements to
earn income. The Fund may enter into repurchase agreements only with financial
institutions that are deemed by the Manager or Subadvisor to be creditworthy,
pursuant to guidelines established by the

22    MainStay U.S. Small Cap Fund



Fund's Board. Repurchase agreements are considered under the 1940 Act to be
collateralized loans by a Fund to the seller secured by the securities
transferred to the Fund.

When the Fund invests in repurchase agreements, the Fund's custodian takes
possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
Fund has the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings and possible
realized loss to the Fund.

(H) FUTURES CONTRACTS.  A futures contract is an agreement to purchase or sell a
specified quantity of an underlying instrument at a specified future date and
price, or to make or receive a cash payment based on the value of a financial
instrument (e.g., foreign currency, interest rate, security, or securities
index.) The Fund is subject to equity price risk and interest rate risk in the
normal course of investing in these transactions. 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 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 have minimal counterparty risk as they are
conducted through regulated exchanges that guarantee the futures against default
by the counterparty. The Fund invests in futures contracts to provide an
efficient means of maintaining liquidity while being fully invested in the
market. The Fund's investment in futures contracts and other derivatives may
increase the volatility of the Fund's NAV and may result in a loss to the Fund.

(I) SECURITIES LENDING.  In order to realize additional income, the Fund may
engage in securities lending, subject to the limitations set forth in the 1940
Act, and relevant guidance by the staff of the Securities and Exchange
Commission. In the event the Fund does engage in securities lending, the Fund
will lend through its custodian, State Street Bank and Trust Company ("State
Street"). State Street will manage the Fund's cash collateral in accordance with
the Lending Agreement between the Fund and State Street, and indemnify the
Fund's portfolio against counterparty risk. The loans will be collateralized by
cash or securities at least equal at all times to the market value of the
securities loaned. Collateral will consist of U.S. Government securities, cash
equivalents or irrevocable letters of credit. The Fund may bear the risk of
delay in recovery of, or loss of rights in, the securities loaned should the
borrower of the securities experience financial difficulty. The Fund may also
record realized gain or loss on securities deemed sold due to a borrower's
inability to return securities on loan. The Fund will receive compensation for
lending its securities in the form of fees or retain a portion of interest on
the investment of any cash received as collateral. The Fund also will continue
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.

Although the Fund and New York Life Investments (as defined in Note 3(A)) have
temporarily suspended securities lending, the Fund and New York Life Investments
reserve the right to reinstitute lending when deemed appropriate. The Fund had
no portfolio securities on loan as of April 30, 2010.

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

NOTE 3--FEES AND RELATED PARTY TRANSACTIONS:

(A) MANAGER AND SUBADVISOR.  New York Life Investment Management LLC ("New York
Life Investments" or "Manager"), a registered investment adviser and an
indirect, wholly-owned subsidiary of New York Life Insurance Company ("New York

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)


Management Agreement ("Management Agreement"). The Manager provides offices,
conducts clerical, recordkeeping and bookkeeping services, and keeps most of the
financial and accounting records required to be maintained by the Fund. Except
for the portion of salaries and expenses that are the responsibility of the
Fund, the Manager also pays the salaries and expenses of all personnel
affiliated with the Fund and the operational expenses of the Fund. Epoch
Investment Partners, Inc. ("Epoch" or "Subadvisor"), a registered investment
adviser, is responsible for the day-to-day portfolio management of the Fund.
Pursuant to the terms of an Amended and Restated Subadvisory Agreement
("Subadvisory Agreement") between New York Life Investments and the Subadvisor,
New York Life Investments pays for the services of the Subadvisor.

The Fund pays the Manager a monthly fee for services performed and facilities
furnished at an annual rate of the Fund's average daily net assets as follows:
0.85% on assets up to $1 billion and 0.80% on assets in excess of $1 billion.
The effective management fee rate (exclusive of any applicable
waivers/reimbursements) was 0.85% for the six-month period ended April 30, 2010.

Effective August 1, 2009, New York Life Investments entered into a written
expense limitation agreement under which it has agreed to waive a portion of the
Fund's management fee or reimburse the expenses of the appropriate class of the
Fund so that the total ordinary operating expenses of a class (total ordinary
operating expenses excludes taxes, interest, litigation, extraordinary expenses,
brokerage and other transaction expenses relating to the purchase or sale of
portfolio investments and the fees and expenses of any other funds in which the
Fund invests) do not exceed the following percentages of average daily net
assets: Investor Class, 1.63%; Class A, 1.53%; Class B, 2.38%; Class C, 2.38%;
and Class I, 1.17%. This expense limitation expires on February 28, 2011 and is
reviewed annually by the Board in connection with its review of the Fund's
investment advisory agreements. Based on its review, the Board may agree to
maintain, modify or terminate the agreement.

For the six-month period ended April 30, 2010, New York Life Investments earned
fees from the Fund in the amount of $1,558,294 and waived/reimbursed expenses in
the amount of $170,527.

State Street, 1 Lincoln Street, Boston, Massachusetts 02111, provides sub-
administration and sub-accounting services to the Fund pursuant to an agreement
with New York Life Investments. These services include calculating the daily
NAVs of the Fund, maintaining the general ledger and sub-ledger accounts for the
calculation of the Fund's respective NAVs, and assisting New York Life
Investments in conducting various aspects of the Fund's administrative
operations. For providing these services to the Fund, State Street is
compensated by New York Life Investments.

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

Pursuant to the Investor Class and Class A Plans, the Distributor receives a
monthly distribution fee from the Investor Class and Class A shares at an annual
rate of 0.25% of the average daily net assets of the Investor Class and Class A
shares for distribution or service activities as designated by the Distributor.
Pursuant to the Class B and Class C Plans, Class B and Class C shares of the
Fund pay the Distributor a monthly distribution fee at an annual rate of 0.75%
of the average daily net assets of the Fund's Class B and Class C shares, along
with a service fee at an annual rate of 0.25% of the average daily net assets of
the Class B and Class C shares of the Fund for a total 12b-1 fee of 1.00%. 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 Investor Class and Class A shares were
$11,546 and $6,991, respectively for the six-month period ended April 30, 2010.
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 $58,
$32,249, and $961, respectively, for the six-month period ended April 30, 2010.

(D) TRANSFER, DIVIDEND DISBURSING AND SHAREHOLDER SERVICING AGENT.  NYLIM
Service Company LLC, an affiliate of New York Life Investments, is the Fund's
transfer, dividend disbursing and shareholder servicing agent pursuant to an
agreement between NYLIM Service Company LLC and the Trust. NYLIM Service Company
LLC has entered into an agreement with Boston Financial Data Services, Inc.
("BFDS") pursuant to which BFDS performs certain transfer agent services on
behalf of NYLIM Service Company LLC. Transfer agent expenses incurred by the
Fund for the six-month period ended April 30, 2010, were as follows:

cost of providing transfer agency services. In an effort to reduce total
transfer agency expenses, the Fund has implemented a small account fee

24    MainStay U.S. Small Cap Fund



on certain types of accounts. Certain shareholders with an account balance of
less than $1,000 are charged an annual per account fee of $20 (assessed semi-
annually). These fees are included in transfer agent fees shown on the Statement
of Operations.

(F) CAPITAL.  At April 30, 2010, New York Life and its affiliates beneficially

NOTE 4--FEDERAL INCOME TAX:

At October 31, 2009, for federal income tax purposes, capital loss carryforwards
of $254,741,846 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. The Fund acquired $22,808,254 of capital losses in its
reorganization with the MainStay Small Cap Value Fund (See Note 9); use of these
losses may be limited due to the provisions of IRC Section 382. 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. No capital gain distributions shall be made until any capital loss
carryforwards have been fully utilized or expired.

of banks in order to secure a source of funds for temporary purposes to meet
unanticipated or excessive shareholder redemption requests.

The line of credit is in the amount of $125,000,000 and the commitment fee rate
is an annual rate of 0.10% of the average commitment amount, plus a 0.04% up-
front payment payable, regardless of usage, to The Bank of New York Mellon,
which serves as agent to the syndicate. The commitment fee and upfront payment
are allocated among certain MainStay Funds based upon net assets and other
factors. Interest on any revolving credit loan is charged based upon the Federal

(a) In addition to any automatic conversion features described above in Note 1
    with respect to Investor Class, Class A and B shares, you generally may also
    elect to convert your shares on a voluntary basis into another share class
    of the same fund for which you are eligible. However, the following
    limitations apply:

   -  Investor Class and Class A shares that remain subject to a CDSC are
      ineligible for a voluntary conversion; and

   -  All Class B and C shares are ineligible for a voluntary conversion.

These limitations do not impact any automatic conversion features described in
Note 1 with respect to Investor Class, Class A and B shares.

An investor or an investor's financial intermediary may contact the Fund to
request a voluntary conversion between shares classes of the same Fund. You may
be required to provide sufficient information to establish eligibility to
convert to the new share class. All permissible conversions will be made on the
basis of the relevant NAVs of the two classes without the imposition of any
sales load, fee or other charge. If you fail to remain eligible for the new
share class, you may automatically be converted back to your original share
class, or into another share class, if appropriate.

NOTE 9--FUND ACQUISITION:

At a meeting held on September 25, 2008, the Board approved a plan of
reorganization where the Fund would acquire the assets, including the
investments, and assume the identified liabilities of MainStay Small Cap Value
Fund, a series of The MainStay Funds. Shareholders of the MainStay Small Cap
Value Fund approved this reorganization on January 30, 2009, which was then
completed on February 13, 2009. The aggregate net assets of the Fund immediately
before the acquisition were $140,597,322 and the combined net assets after the
acquisition were $169,213,965.

The acquisition was accomplished by a tax-free exchange of the following:

MainStay Small Cap Growth Fund's net assets after adjustments for any permanent

the following amounts of capital stock, unrealized appreciation and accumulated
net realized loss:

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

</Table>


Assuming the acquisition had been completed on November 1, 2010, the beginning
of the annual reporting period of the Fund, the Fund's pro forma results of
operations for the period ended April 30, 2010, are as follows:

<Table>
                                  
Net investment income                $   373,210

Net gain on investments              $67,597,951
- ------------------------------------------------
Net increase in net assets
  resulting from operations          $67,971,161
- ------------------------------------------------

</Table>


Because the combined investment portfolios have been managed as a single
integrated portfolio since the acquisition was completed, it is not practicable
to separate the amounts of revenue and earnings of the MainStay Small Cap Growth
Fund that have been included in the Fund's Statement of Operations since October
31, 2009.

In December 2007, the Financial Accounting Standards Board issued Accounting
Standards Codification (ASC) 805 (formerly FAS 141R Business Combinations),
which requires the following disclosures by the acquirer, among other things,
when a transaction or other event meets the definition of a business
combination:

- - The identification of the acquiree

- - Recognizing and measuring identifiable assets acquired and liabilities
  assumed, at the acquisition date, generally at their fair values

- - Disclosure, by the acquirer, of information that enables users of its
  financial statements to evaluate the nature and financial effect of a business
  combination that occurs during the current reporting period

ASC 805 requires prospective application to business combinations for which the
acquisition date occurs in an annual reporting period beginning on or after
December 15, 2008.

In accordance with ASC 805, for financial reporting purposes, assets received
and shares issued by the Fund were recorded at fair value; however, the cost
basis of the investments received from MainStay Small Cap GrowthFund was carried
forward to align ongoing reporting of the Fund's realized and unrealized gains
and losses with amounts distributable to shareholders for tax purposes.

ASC 805 requires disclosure in this semi-annual report, and in the Fund's annual
report as of October 31, 2010, of the Fund's pro-forma results of operations,
including net investment income, net gain (loss) on investments and net increase
(decrease) in net assets resulting from operations, assuming the acquisition had
been completed on November 1, 2009, the beginning of the annual reporting period
of the Fund, through the end of the applicable reporting period.

ASC 805 also requires the Fund to report, if practicable, the amounts of revenue
and earnings of the acquiree since the acquisition date included in the combined
entity's income statement for the reporting period. Because the combined
investment portfolios have been managed as a single integrated portfolio since
the acquisition was completed, it is not practicable to separate the amounts of
revenue and earnings of the MainStay Small Cap Growth Fund that will be included
in the Fund's Statement of Operations since November 24, 2009.

NOTE 10--NEW ACCOUNTING PRONOUNCEMENT:

In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements". ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value
measurements that fall in either Level 2 or Level 3, and information on
purchased, sales, issuances, and settlements in the roll forward of activity in
Level 3 fair value measures. The new and revised disclosure requirements are
effective for interim and annual reporting periods beginning after December 15,
2009 except for the disclosures about purchased, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures,
which are effective for fiscal years beginning after December 15, 2010. As of
April 30, 2010, the Fund has adopted ASU 2010-06. The adoption of ASU 2010-06
has not impacted the amounts reported in the financial statements; however,
there are additional disclosures in the Portfolio of Investments.

NOTE 11--SUBSEQUENT EVENTS:

In connection with the preparation of the financial statements of the Fund as of
and for the fiscal six-month period ended April 30, 2010, events and
transactions subsequent to April 30, 2010 through the date the financial
statements were issued have been evaluated by the Fund's management for possible
adjustment and/or disclosure. No subsequent events requiring financial statement
adjustment or disclosure have been identified.

        MESSAGE FROM THE PRESIDENT AND SEMIANNUAL REPORT

        Unaudited - April 30, 2010



MESSAGE FROM THE PRESIDENT

During the six months ended April 30, 2010, stock and bond markets generally
advanced, despite some volatility in January and February. Domestic small-cap
stocks were particularly strong, and U.S. stocks at all capitalization levels
provided double digit returns. Value stocks outpaced growth stocks for companies
of all sizes during the reporting period.

International stocks provided positive returns overall, but results varied
widely by country. Concerns about Greece's ability to meet its debt obligations
led many investors to abandon their holdings in Greece and question their
investments in several peripheral European nations where perceived risk had
increased. For the six-month reporting period, equities in the Far East
(including Japan) tended to be stronger than those in Europe.

The economic recovery in the United States continued. Real gross domestic
product advanced in the first quarter of 2010, though at a slower pace than in
the fourth quarter of 2009. The Federal Open Market Committee kept the targeted
federal funds rate at a historically low level throughout the reporting period,
which prompted many investors to leave the safety of U.S. Treasury securities in
search of higher yield.

In the high-yield bond market, lower-rated credits tended to be the strongest
performers. With investment-grade investors crossing into high-yield territory,
however, the highest-rated high-yield credits also saw strong demand. In the
municipal market, new-issue supply was reduced by government incentives that
encouraged municipal issuers to raise funds in the taxable market. In the
leveraged-loan market, new issuance strengthened, but extensive repayments
caused the market as a whole to contract.


Throughout the six-month reporting period, MainStay's portfolio managers sought
to make the most of market conditions within the investment strategies and risk
parameters of their respective Funds. While individual markets and Fund results
may vary, our pursuit of competitive returns over full market cycles has never
changed.

The information that follows provides a closer look
at the securities, strategies and market conditions that affected your MainStay
Fund(s) during the six months ended April 30, 2010. Of course, past performance
is no guarantee of future results. Even in a rising market, we believe that
maintaining a long-term perspective can be valuable. At MainStay, we believe
that in all markets, broad diversification, gradual allocation adjustments and
regular portfolio reviews can help guide you toward your long-range financial
goals.

We thank you for choosing MainStay Funds, and we look forward to serving your
investment needs for many years to come.

Sincerely,

/s/ STEPHEN P. FISHER

Stephen P. Fisher
President

1.  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 maximum applicable sales charges explained in this
    paragraph, change in share price, and reinvestment of dividend and capital
    gain distributions. The graphs assume an initial investment of $25,000 for
    Class A shares and $10,000 for all other classes and reflect the deduction
    of all sales charges that would have applied for the period of investment.
    Class A shares generally have a $25,000 minimum initial investment with no
    minimum subsequent purchase amount. For investors that, in the aggregate,
    have assets of $100,000 or more invested in any share classes of any of the
    MainStay Funds, the minimum initial investment is $15,000. Investor Class
    shares and Class A shares are sold with a maximum initial sales charge of
    5.50% and an annual 12b-1 fee of 0.25%. Class B shares are sold with no
    initial sales charge, are subject to a contingent deferred sales charge
    ("CDSC") of up to 5.00% 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 1.00% 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 or individual
    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 0.25%. Class R1 and R2 shares are available only through

COST IN DOLLARS OF A $1,000 INVESTMENT IN MAINSTAY BALANCED FUND (UNAUDITED)
- --------------------------------------------------------------------------------

The example below is intended to describe the fees and expenses borne by
shareholders during the six-month period from November 1, 2009, to April 30,
2010, 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, exchange fees, and sales charges (loads) on
purchases (as applicable), and (2) ongoing costs, including management fees,
distribution and/or service (12b-1) fees, and other Fund expenses (as
applicable). 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 November 1, 2009, to April 30, 2010.

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 April 30, 2010. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During Period" to estimate the expenses you paid on your account during this
period.

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

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

   (1.45% for Investor Class, 1.27% for Class A, 2.21% for Class B and Class C,
   1.01% for Class I, 1.11% for Class R1, 1.37% for Class R2 and 1.62% for Class
   R3) multiplied by the average account value over the period, divided by 365
   and multiplied by 181 (to reflect the one-half year period). The table above
   represents the actual expenses incurred during the one-half year period.

PORTFOLIO MANAGEMENT DISCUSSION AND ANALYSIS


QUESTIONS ANSWERED BY PORTFOLIO MANAGERS TONY H. ELAVIA OF MADISON SQUARE
INVESTORS LLC, THE FUND'S SUBADVISOR, AND THOMAS J. GIRARD OF NEW YORK LIFE
INVESTMENTS,(1) THE FUND'S MANAGER.


HOW DID MAINSTAY BALANCED FUND PERFORM RELATIVE TO ITS PEERS AND ITS BENCHMARK
DURING THE SIX MONTHS ENDED APRIL 30, 2010?

Excluding all sales charges, MainStay Balanced Fund returned 12.54% for Investor
Class shares, 12.61%
for Class A shares and 12.12% for both Class B and Class C shares for the six
months ended April 30, 2010. Over the same period, Class I shares returned
12.82%, Class R1 shares returned 12.73%, Class R2 shares returned 12.60% and
Class R3 shares returned 12.47%. All share classes outperformed the 11.01%
return of the average Lipper(2) mixed-asset target allocation growth fund. All
share classes underperformed the 26.54% return of the Russell Midcap(R) Value
Index(3) and the 16.46% return of the Fund's Balanced Composite Index(4) for the
six months ended April 30, 2010. The Russell Midcap(R) Value Index is the Fund's
broad-based securities-market index. The Balanced Composite Index is a secondary
benchmark of the Fund. See pages 5 and 6 for Fund returns with sales charges.

WHAT FACTORS WERE RESPONSIBLE FOR THE FUND'S RELATIVE PERFORMANCE DURING THE
REPORTING PERIOD?

The Fund invests in a mix of stocks and bonds, while the Russell Midcap(R) Value
Index consists entirely of mid-cap value stocks. Since the Fund has a
substantial allocation to bonds, which underperformed the Russell Midcap(R)
Value Index, the Fund by its very composition trailed the benchmark index by a
substantial margin. With the Fund's asset-allocation targets taken into account,
however, overall performance was roughly in line with our expectations.

The equity portion of the Fund underperformed the Russell Midcap(R) Value Index
primarily because of its bias toward higher-quality stocks generally associated
with stable, consistent earnings growth. When the equity market turned positive
in the spring of 2009, investors aggressively bought the riskiest, lowest-
quality securities in anticipation that these securities would benefit most from
a recovery. This trend persisted throughout the reporting period, and stocks
with negative earnings and cash flows were among the best performers. This so-
called junk rally served as a significant drag on the relative performance of
the equity portion of the Fund.

The fixed-income portion of the Fund outperformed the 2.34% return of the Bank
of America Merrill Lynch 1-10 Years U.S. Corporate & Government Index(5) for the
six months ended April 30, 2010. An underweight position in Treasury securities
and overweight positions in investment-grade corporate securities and commercial
mortgage-backed securities were the strongest contributors to outperformance in
this portion of the Fund.

Relative to its Lipper peers, the Fund benefited by maintaining a focus on mid-
capitalization stocks. Mid-cap stocks modestly trailed their small-cap
counterparts but significantly outpaced larger-cap stocks during the reporting
period.

DURING THE REPORTING PERIOD, WHICH EQUITY SECTORS WERE THE STRONGEST
CONTRIBUTORS TO THE FUND'S PERFORMANCE AND WHICH EQUITY SECTORS WERE THE
WEAKEST?

The equity portion of the Fund utilizes a proprietary quantitative investment
process that focuses on a combination of valuation, growth and momentum factors.
Sector holdings are a residual of the Fund's investment process and are not a
product of top-down, macroeconomic analysis.

As the largest sector within the Fund (and among mid-cap value stocks),
financials made the most significant contribution to the Fund's absolute
performance, even though the sector's results were unremarkable relative to the
broader equity market. Financials were torn between a strong earnings recovery
on the one hand and continued concerns about loan-loss provisioning on the
other. Consumer discretionary and industrial holdings also made strong
contributions to the Fund's absolute returns. Consumer discretionary stocks
benefited from a rebound in retail sales. Industrials enjoyed a tailwind from
inventory restocking and a jump in global trade.

While all sectors of the Russell Midcap(R) Value Index generated positive
returns during the reporting period, telecommunication services had the smallest
allocation in the Fund and made the smallest contribution to the Fund's absolute
performance. Other sectors that fared comparatively poorly included consumer
staples and utilities, both of which are often viewed as defensive, low-
volatility sectors. Indeed, we believe that these sectors can be expected to lag
a sharply rising market.

DURING THE REPORTING PERIOD, WHICH STOCKS WERE THE STRONGEST CONTRIBUTORS TO THE
FUND'S ABSO-LUTE PERFORMANCE AND WHICH STOCKS DETRACTED THE MOST?

In the equity portion of the Fund, the strongest individual contributors to
absolute performance were bank holding company Regions Financial, chemical
company Ashland and engine manufacturer Cummins.

Very few holdings actually detracted from the Fund's absolute performance during
the reporting period. However, among those that did were offshore driller Ensco,
investment manager BlackRock and mining operator Freeport-McMoRan Copper & Gold.

DID THE EQUITY PORTION OF THE FUND MAKE ANY SIGNIFICANT PURCHASES OR SALES
DURING THE REPORTING PERIOD?

The equity portion of the Fund is broadly diversified, so individual purchases
and sales tend to have little impact on overall results. The Fund selects
securities using a proprietary investment process that seeks stocks with
attractive relative valuations, strong operating results and positive price
trends.

Among the stocks that fit the Fund's purchase criteria during the reporting
period were automobile manufacturer Ford Motor and casino operator Las Vegas
Sands. In our view, these attractively priced but volatile stocks were poised to
do well should risk capital continue to flow back into the equity markets.
Mining operator Freeport-McMoRan Copper & Gold was another significant purchase
during the reporting period. We felt that that the company was likely to benefit
from a global recovery led by commodity-intensive emerging economies.

Stocks sold during the reporting period included global consumer goods company
Colgate-Palmolive, retailer Coach and tobacco producer Lorillard.

HOW DID SECTOR WEIGHTINGS CHANGE IN THE EQUITY PORTION OF THE FUND DURING THE
REPORTING PERIOD?

Weighting changes in the equity portion of the Fund resulted from a combination
of stock performance and the Fund's proprietary quantitative security- selection
process. During the reporting period, we increased the Fund's weightings in the
health care and consumer discretionary sectors. We increased the Fund's health
care weighting on the belief that the passage of health care legislation had
removed much of the uncertainty regarding the sector's prospects. We increased
exposure to the consumer discretionary sector in anticipation of continued
economic recovery and a rebound in retail sales.

Similar expectations led us to reduce the Fund's weighting in the consumer
staples sector. We also reduced the Fund's exposure to the telecommunication
services and financials sectors during the reporting period.

In all cases, sector changes were relatively modest, as managing industry and
sector allocation is not a central element in the Fund's investment process.

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

As of April 30, 2010, the equity portion of the Fund was moderately overweight
relative to the Russell Midcap(R) Value Index in health care and energy. As of
the same date, the equity portion of the Fund was underweight relative to the
benchmark in financials and utilities. To some degree, this positioning is
simply a by-product of the Fund's investment process and does not reflect a
deliberate expression of our opinion regarding the relative outlook for these
sectors.

WHAT FACTORS AFFECTED THE FIXED-INCOME PORTION OF THE FUND DURING THE REPORTING
PERIOD?

The most significant factors that influenced the fixed-income markets during the
reporting period were the economic recovery that appeared to gain momentum as
the period progressed and the continued rebound in the financial markets. While
the equity markets seemed to hit a low point in March 2009, spreads(6) on non-
Treasury bonds appeared to have reached their widest levels at approximately the
same time. Equity markets continued their rebound through much of the reporting
period, and non-Treasury bond spreads tightened significantly. In addition,
assets flowed out of money market funds in search of higher yields, and a
significant portion of that money targeted the broader fixed-income market, and
particularly corporate bonds. Such a widespread trend in fund flows made it
increasingly difficult to ascertain value and find appropriate securities for
the Fund.

With relatively low inflation, the Federal Reserve was able to sit on the
sidelines and exercise patience in its monetary policy decisions. It allowed
most of its emergency programs to expire, with little discernable impact on the
bond market. Federal Reserve forecasts

6. The terms "spread" and "yield spread" may refer to the difference in yield
   between a 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.

include keeping short-term interest rates very low for an extended period of
time.

The economy continued to show modest improvement, but the recovery was subpar
relative to prior recoveries. The most glaring weakness was the labor market,
which has only recently begun to create jobs. Unemployment remained unacceptably
high, and policy makers appeared to be waiting for meaningful improvements
before significantly tightening monetary policy.

Uncertainty about U.S. financial reform legislation and its impact on financial
institutions kept spreads on bank and finance paper wider than normal relative
to spreads on utility or industrial bonds. Concerns surrounding Greek sovereign
debt--and whether there would be a default or a bailout--created volatility in
the U.S. Treasury market and the corporate bond market.

HOW DID THE FIXED-INCOME PORTION OF THE FUND RESPOND TO THESE MARKET FORCES?

In the fixed-income portion of the Fund, we sold Treasury securities and
purchased commercial mortgage-backed securities and investment-grade corporate
bonds early in the reporting period. These trades modestly shortened the Fund's
duration. Each of these strategies helped the fixed-income portion of the Fund
outperform the Bank of America Merrill Lynch Corporate & Government 1-10 Years
Bond Index during the reporting period. Later in the reporting period, we moved
the Fund's duration closer to that of the Bank of America Merrill Lynch 1-10
Years U.S. Corporate & Government Index to help mitigate interest-rate risk.

NOTES TO FINANCIAL STATEMENTS UNAUDITED

NOTE 1--ORGANIZATION AND BUSINESS:

Eclipse Funds (the "Trust") was organized on July 30, 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 is comprised of two funds (collectively referred to as the "Funds"). These
financial statements and notes relate only to the MainStay Balanced Fund (the
"Fund"), a diversified fund.

The Fund currently offers eight classes of shares. Class I shares commenced
operations on May 1, 1989. Class C shares commenced operations on December 30,
2002. Class A shares, Class B shares, Class R1 shares and Class R2 shares
commenced operations on January 2, 2004. Class R3 shares commenced operations on
April 28, 2006. Investor Class shares commenced operations on February 28, 2008.
Investor Class and Class A shares are offered at net asset value ("NAV") per
share plus an initial sales charge. No sales charge applies on investments of $1
million or more (and certain other qualified purchases) in Investor Class and
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 at NAV without an initial sales charge,
although a declining contingent deferred sales charge may be imposed on
redemptions made within six years of purchase of Class B shares and a 1.00%
contingent deferred sales charge may be imposed on redemptions made within one
year of purchase of Class C shares. Class I, Class R1, Class R2 and Class R3
shares are offered at NAV and are not subject to a sales charge. Depending upon
eligibility, Class B shares convert to either Investor Class or Class A shares
eight years after the date they were purchased. Additionally, depending upon
eligibility, Investor Class shares may convert to Class A shares and Class A
shares may convert to Investor Class shares. The eight classes of shares have
the same voting (except for issues that relate solely to one class), dividend,
liquidation and other rights, and the same terms and conditions, except that
Class B and Class C shares are subject to higher distribution and/or service fee
rates than Investor Class, Class A, Class R2 and Class R3 shares under a
distribution plan pursuant to Rule 12b-1 under the 1940 Act. Class I and Class
R1 shares are not subject to a distribution and/or service fee. Class R1, Class
R2 and Class R3 shares are authorized to pay a shareholder service fee to the
Manager, as defined in Note 3(A), its affiliates, or third-party service
providers, as compensation for services rendered to shareholders of Class R1,
Class R2 or Class R3 shares.

The Fund's investment objective is to seek high total return.

NOTE 2--SIGNIFICANT ACCOUNTING POLICIES:

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

(A) SECURITIES VALUATION.  Debt securities are valued at prices supplied by a
pricing agent or broker selected by the Fund's Manager (as defined in Note 3(A))
in consultation with the Fund's Subadvisor, if any (as defined in Note 3(A)),
whose prices reflect broker/dealer supplied valuations and electronic data
processing techniques, if such prices are deemed by the Fund's Manager, in
consultation with the Fund's Subadvisor, if any, to be representative of market
values, at the regular close of trading of the New York Stock Exchange
("Exchange") (generally 4:00 p.m. Eastern time) on each day the Fund is open for
business ("valuation date").

Equity securities are valued at the latest quoted sales prices as of the close
of regular trading on the Exchange on each valuation date. Securities that are
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. Futures contracts are valued at the last posted settlement
price on the market where such futures are primarily traded. Investments in
other mutual funds are valued at their NAVs as of the close of the Exchange on
the valuation date.

Temporary cash investments acquired over 60 days prior to maturity are valued
using the latest bid prices or using valuations based on a matrix system (which
considers such factors as security prices, yields, maturities, and ratings),
both as furnished by independent pricing services. Other temporary cash
investments which mature in 60 days or less ("short-term investments") are
valued at 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 the principal amount due at
maturity and cost.

Securities for which market quotations are not readily available are valued by
methods deemed in good faith by the Fund's Board to represent fair value. Equity
and non-equity securities which may be valued in this manner include, but are
not limited to: (i) a security the trading for which has been halted or
suspended; (ii) a debt security that has recently gone into default and for
which there is not a current market quotation; (iii) a security of an issuer
that has entered into a restructuring; (iv) a security that has been de-listed
from a national exchange; (v) a security the market price of which is not
available from an independent pricing source or, if so provided, does not, in
the opinion of the Fund's Manager or Subadvisor, as defined in Note 3(A),
reflect the security's market value; and (vi) a security where the trading on
that security's principal market is temporarily closed at a time when, under
normal conditions, it would be open. At April 30, 2010, the Fund held securities
with a value of $18 that were valued in such a manner.


30    MainStay Balanced Fund



"Fair value" is defined as the price that the Fund would receive upon selling an
investment in an orderly transaction to an independent buyer in the principal or
most advantageous market of the investment. Fair value measurements are
determined within a framework that has established a three-tier hierarchy which
maximizes the use of observable market data and minimizes the use of
unobservable inputs to establish classification of fair value measurements for
disclosure purposes. "Inputs" refer broadly to the assumptions that market
participants would use in pricing the asset or liability, including assumptions
about risk, such as the risk inherent in a particular valuation technique used
to measure fair value using a pricing model and/or the risk inherent in the
inputs for the valuation technique. Inputs may be observable or unobservable.
Observable inputs are inputs that reflect the assumptions market participants
would use in pricing the asset or liability based on market data obtained from
sources independent of the reporting entity. Unobservable inputs are inputs that
reflect the reporting entity's own assumptions about the assumptions market
participants would use in pricing the asset or liability developed based on the
information available in the circumstances. The inputs or methodology used for
valuing securities may not be an indication of the risks associated with
investing in those securities. The three-tier hierarchy of inputs is summarized
in the three broad Levels listed below.

- - Level 1--quoted prices in active markets for identical investments

- - Level 2--other significant observable inputs (including quoted prices for
  similar investments in active markets, interest rates and yield curves,
  prepayment speeds, credit risks, etc.)

- - Level 3--significant unobservable inputs (including the Fund's own assumptions
  about the assumptions that market participants would use in determining the
  fair value of investments)

The aggregate value by input level, as of April 30, 2010, for the Fund's
investments is included at the end of the Fund's Portfolio of Investments.

The valuation techniques used by the Fund to measure fair value during the six-
month period ended April 30, 2010 maximized the use of observable inputs and
minimized the use of unobservable inputs. The Fund may have utilized some of the
following fair value techniques: multi-dimensional relational pricing models,
option adjusted spread pricing and estimating the price that would have
prevailed in a liquid market for an international equity security given
information available at the time of evaluation, when there are significant
events after the close of local foreign markets. For the six-month period ended
April 30, 2010, there have been no changes to the fair value methodologies.

Generally, a security is considered illiquid if it cannot be sold or disposed of
in the ordinary course of business at approximately the price at which it is
valued. Its illiquidity might prevent the sale of such security at a time when
the Manager or Subadvisor, if any, as defined in Note 3(A) might wish to sell,
and these securities could have the effect of decreasing the overall level of a
Fund's liquidity. Further, the lack of an established secondary market may make
it more difficult to value illiquid securities, requiring the Fund to rely on
judgments that may be somewhat subjective in determining value, which could vary
from the amount that the Fund could realize upon disposition. Difficulty in
selling illiquid securities may result in a loss or may be costly to the Fund.
Under the supervision of the Board, the Manager or Subadvisor, if any,
determines the liquidity of a Fund's investments; in doing so, the Manager or
Subadvisor, if any, may consider various factors, including (1) the frequency of
trades and quotations, (2) the number of dealers and prospective purchasers, (3)
the dealer undertakings to make a market, and (4) the nature of the security and
the market in which it trades (e.g., the time needed to dispose of the security,
the method of soliciting offers and the mechanics of transfer). Illiquid
securities generally will be valued in such manner, as the Board in good faith
deems appropriate to reflect their fair market value.

(B) FEDERAL INCOME TAXES.  The Fund's policy is to comply with the requirements
of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code")
applicable to regulated investment companies and to distribute all of the
taxable income to the shareholders of the Fund within the allowable time limits.
Therefore, no federal income tax provision is required.

Management evaluates its tax positions to determine if the tax positions taken
meet the minimum recognition threshold in connection with accounting for
uncertainties in income tax positions taken or expected to be taken for the
purposes of measuring and recognizing tax liabilities in the financial
statements. Recognition of tax benefits of an uncertain tax position is required
only when the position is "more likely than not" to be sustained assuming
examination by taxing authorities. Management has analyzed the Fund's tax
positions taken on federal income tax returns for all open tax years (current
and prior three tax years), and has concluded that no provision for federal
income tax is required in the Fund's financial statements. The Fund's federal
and state income and federal excise tax returns for tax years for which the
applicable statutes of limitations have not expired are subject to examination
by the Internal Revenue Service and state departments of revenue.

(C) DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS.  Dividends and distributions
are recorded on the ex-dividend date. The Fund intends to declare and pay
dividends of net investment income, if any, quarterly and distributions of net
realized capital and currency gains, if any, annually. Unless the shareholder
elects otherwise, all dividends and distributions are reinvested in the same
class of shares of

                                                   mainstayinvestments.com    31



NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)



the Fund, at NAV. Dividends and distributions to shareholders are determined in
accordance with federal income tax regulations and may differ from GAAP.

(D) SECURITY TRANSACTIONS AND INVESTMENT INCOME.  The Fund records security
transactions on the trade date. Realized gains and losses on security
transactions are determined using the identified cost method and include gains
and losses from repayments of principal on mortgage-backed securities. Dividend
income is recognized on the ex-dividend date and interest income is accrued as
earned using the effective interest rate method. Discounts and premiums on
securities purchased, other than short-term investments, for the Fund are
accreted and amortized, respectively, on the effective interest rate method over
the life of the respective securities or, in the case of a callable security,
over the period to the first date of call. Discounts and premiums on short-term
investments 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 pro rata based upon their
relative net assets on the date the income is earned or realized and unrealized
gains and losses are incurred.

(E) EXPENSES.  Expenses of the Trust are allocated to the individual Funds in
proportion to the net assets of the respective Funds when the expenses are
incurred, except where direct allocations of expenses can be made. Expenses
(other than transfer agent expenses and fees incurred under the shareholder
services plans and the distribution plans further discussed in Note 3(B)) are
allocated to separate classes of shares pro rata based upon their relative NAV
on the date the expenses are incurred. The expenses borne by the Fund, including
those of related parties to the Fund, are shown in the Statement of Operations.

(F) USE OF ESTIMATES.  In preparing financial statements in conformity with
GAAP, management makes estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those estimates.

(G) REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements to
earn income. The Fund may enter into repurchase agreements only with financial
institutions that are deemed by the Manager or Subadvisor to be creditworthy,
pursuant to guidelines established by the Fund's Board. Repurchase agreements
are considered under the 1940 Act to be collateralized loans by a Fund to the
seller secured by the securities transferred to the Fund.

When the Fund invests in repurchase agreements, the Fund's custodian takes
possession of the collateral pledged for investments in such repurchase
agreements. The underlying collateral is valued daily on a mark-to-market basis
to determine that the value, including accrued interest, exceeds the repurchase
price. In the event of the seller's default of the obligation to repurchase, the
Fund has the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Under certain circumstances, in the event of
default or bankruptcy by the other party to the agreement, realization and/or
retention of the collateral may be subject to legal proceedings and possible
realized loss to the Fund.

(H) FUTURES CONTRACTS.  A futures contract is an agreement to purchase or sell a
specified quantity of an underlying instrument at a specified future date and
price, or to make or receive a cash payment based on the value of a financial
instrument (e.g., foreign currency, interest rate, security, or securities
index.) The Fund is subject to equity price risk and interest rate risk in the
normal course of investing in these transactions. 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 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 have minimal counterparty risk as they are
conducted through regulated exchanges that guarantee the futures against default
by the counterparty. The Fund invests in futures contracts to help manage the
duration and yield curve of the portfolio while minimizing the exposure to wider
bid/ask spreads in traditional bonds. The Fund's investment in futures contracts
and other derivatives may increase the volatility of the Fund's NAV and may
result in a loss to the Fund.

(I) SECURITIES LENDING.  In order to realize additional income, the Fund may
engage in securities lending, subject to the limitations set forth in the 1940
Act, and relevant guidance by the staff of the Securities and Exchange
Commission. In the event the Fund does engage in securities lending, the Fund
will lend through its custodian, State Street Bank and Trust Company ("State
Street"). State Street will manage the Fund's cash collateral in accordance with
the Lending Agreement between the Fund and State Street, and indemnify the
Fund's portfolio against counterparty risk. The loans will be collateralized by
cash or securities at

32    MainStay Balanced Fund



least equal at all times to the market value of the securities loaned.
Collateral will consist of U.S. Government securities, cash equivalents or
irrevocable letters of credit. The Fund may bear the risk of delay in recovery
of, or loss of rights in, the securities loaned should the borrower of the
securities experience financial difficulty. The Fund may also record realized
gain or loss on securities deemed sold due to a borrower's inability to return
securities on loan. The Fund will receive compensation for lending its
securities in the form of fees or retain a portion of interest on the investment
of any cash received as collateral. The Fund also will continue 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.

Although the Fund and New York Life Investments (as defined in Note 3(A)) have
temporarily suspended securities lending, the Fund and New York Life Investments
reserve the right to reinstitute lending when deemed appropriate. The Fund had
no portfolio securities on loan as of April 30, 2010.

(J) RESTRICTED SECURITIES.  A restricted security is a security which has been
purchased through a private offering and cannot be resold to the general public
without prior registration under the Securities Act of 1933. The Fund may not
have the right to demand that such securities be registered. Disposal of these
securities may involve time-consuming negotiations and expenses and it may be
difficult to obtain a prompt sale at an acceptable price. (See Note 5.)

(K) CONCENTRATION OF RISK.  The ability of issuers of debt securities held by
the Fund to meet their obligations may be affected by economic or political
developments in a specific country, industry or region.

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

(M) QUANTITATIVE DISCLOSURE OF DERIVATIVE HOLDINGS.  The following tables show
additional disclosures about the Fund's derivative and hedging activities,
including how such activities are accounted for and their effect on the Fund's
financial positions, performance and cash flows. These derivatives are not
accounted for as hedging instruments.

month period ended April 30, 2010.

reimbursements) was 0.70% for the six-month period ended April 30, 2010.

Effective August 1, 2009, New York Life Investments entered into a written
expense limitation agreement under which it has agreed to waive a portion of the
management fee or reimburse expenses to the extent necessary to ensure that the
total ordinary operating expenses (total ordinary operating expenses excludes
taxes, interest, litigation, extraordinary expenses, brokerage, other
transaction expenses relating to the purchase or sale of portfolio investments,
and the fees and expenses of any other funds in which the Fund invests) for the
Fund's Class A shares do not exceed 1.28% of its average net assets. New York
Life Investments will apply an equivalent waiver or reimbursement, in an equal
number of basis points, to the other share classes of the Fund. This agreement
expires on July 31, 2010 and is reviewed annually by the Board in connection
with its review of the Fund's investment advisory agreements. Based on its
review, the Board may agree to maintain, modify or terminate the agreement.

For the six-month period ended April 30, 2010, New York Life Investments earned
fees from the Fund in the amount of $2,311,877.

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.

In accordance with the Shareholder Services Plans for the Class R1, Class R2 and
Class R3 shares, the Manager has agreed to provide, through its affiliates or

(a) In addition to any automatic conversion features described above in Note 1
    with respect to Investor Class, Class A and B shares, you generally may also
    elect to convert your shares on a voluntary basis into another share class
    of the same fund for which you are eligible. However, the following
    limitations apply:

   - Investor Class and Class A shares that remain subject to a CDSC are
     ineligible for a voluntary conversion; and

   - All Class B and C shares are ineligible for a voluntary conversion.

These limitations do not impact any automatic conversion features described in
Note 1 with respect to Investor Class, Class A and B shares.

NOTES TO FINANCIAL STATEMENTS UNAUDITED (CONTINUED)


An investor or an investor's financial intermediary may contact the Fund to
request a voluntary conversion between shares classes of the same Fund. You may
be required to provide sufficient information to establish eligibility to
convert to the new share class. All permissible conversions will be made on the
basis of the relevant NAVs of the two classes without the imposition of any
sales load, fee or other charge. If you fail to remain eligible for the new
share class, you may automatically be converted back to your original share
class, or into another share class, if appropriate.

NOTE 10--NEW ACCOUNTING PRONOUNCEMENT:

In January 2010, the Financial Accounting Standards Board ("FASB") issued
Accounting Standards Update ("ASU") No. 2010-06 "Improving Disclosures about
Fair Value Measurements". ASU 2010-06 requires reporting entities to make new
disclosures about amount and reasons for significant transfers in and out of
Level 1 and Level 2 fair value measurements and input and valuation techniques
used to measure fair value for both recurring and nonrecurring fair value
measurements that fall in either Level 2 or Level 3, and information on
purchased, sales, issuances, and settlements in the roll forward of activity in
Level 3 fair value measures. The new and revised disclosure requirements are
effective for interim and annual reporting periods beginning after December 15,
2009 except for the disclosures about purchased, sales, issuances, and
settlements in the roll forward of activity in Level 3 fair value measures,
which are effective for fiscal years beginning after December 15, 2010. As of
April 30, 2010, the Fund has adopted ASU 2010-06. The adoption of ASU 2010-06
has not impacted the amounts reported in the financial statements; however,
there are additional disclosures in the Portfolio of Investments.

NOTE 11--SUBSEQUENT EVENTS:

In connection with the preparation of the financial statements of the Fund as of
and for the fiscal six-month period ended April 30, 2010, events and
transactions subsequent to April 30, 2010 through the date the financial
statements were issued have been evaluated by the Fund's management for possible
adjustment and/or disclosure. No subsequent events requiring financial statement
adjustment or disclosure have been identified.
