MARKET CONDITIONS

The stock market performed reasonably well for the 12-month period. Although a
number of factors contributed to pockets of turbulence, market conditions
remained relatively calm until the final months of the period. Early in the
period, positive economic data, strong consumer confidence and healthy corporate
earnings buoyed investor sentiment. However, in August, the Gulf Coast
hurricanes sent oil prices spiking and consumer data appeared to falter,
increasing anxiety about future economic growth. By October, optimism returned
to the markets as the economy proved more resilient than expected. Although
December's gain was lackluster due to concerns about high gold prices, ongoing
difficulties in the auto industry, additional monetary tightening by the Federal
Open Market Committee (the "Fed") and the flattening yield curve, stocks rallied
strongly in January. The market exhibited a pronounced "January Effect"-a
historical trend wherein the market rallies in the first month of the calendar
year, particularly in higher-volatility segments of the market such as small-cap
and technology stocks. Stocks slowed their pace in February as investors became
apprehensive about employment and payroll data and corporate earnings
announcements. Sentiment brightened again in March and April as strong economic
growth data, high-profile merger-and-acquisition activity and more positive
developments on the corporate earnings front gave a boost to the stock market.

However, the market encountered a steep sell-off in May followed by flat
performance in June. The Fed raised the federal funds target rate in both
months, and its accompanying language did little to soothe investors seeking a
respite from monetary tightening.

PERFORMANCE ANALYSIS

Morgan Stanley Equally-Weighted S&P 500 Fund underperformed the S&P Equal Weight
Index for the 12 months ended June 30, 2006, assuming no deduction of applicable
sales charges. The Fund's Class A shares and Class D shares outperformed the
Lipper Multi-Cap Core Funds Index, and the Fund's Class B shares and Class C
shares underperformed the Lipper Multi-Cap Core Funds Index for the same period,
also assuming no deduction of applicable sales charges.

The financials sector added most to the Fund's overall performance during the
period. The strong performance of financial companies with exposure to capital
markets and merger and acquisition activity offset weakness in the banking
stocks. The industrials sector was another source of gains, as a growing global
economy benefited transportation stocks, in particular. The energy sector


                                       2

<Page>

was also among the Fund's leading contributors as the high price of oil and
natural gas continued to drive earnings growth for many energy companies.

In contrast, the consumer discretionary sector was a significant detractor from
the Fund's return. Within the sector, the beleaguered auto and auto components
industries drew increasingly negative sentiment due to the high profile
financial woes of several companies during the period. Home building stocks also
slowed their advance as the rising interest rate environment began to slow
housing trends. The utilities sector also had a negative influence on
performance. Company-specific events drove the sector lower in the first half of
the period. Moreover, a backdrop of rising interest rates led investors to
rotate out of utilities stocks in favor of fixed income investments with more
attractive yields.

From a market-capitalization perspective, mid-cap stocks contributed the most
relative to small- and large-cap stocks. In terms of style, value stocks bested
their growth counterparts during the period.

THERE IS NO GUARANTEE THAT ANY SECTORS MENTIONED WILL CONTINUE TO PERFORM AS
DISCUSSED HEREIN OR THAT SECURITIES IN SUCH SECTORS WILL BE HELD BY THE FUND IN
THE FUTURE.

INVESTMENT STRATEGY

The Fund invests in a diversified portfolio of common stocks represented in the
Standard & Poor's 500(R) Composite Stock Price Index ("S&P 500"). The S&P 500 is
a well known stock market index that includes common stocks of 500 companies.
The Fund generally invests in each stock included in the S&P 500 in
approximately equal proportions. This approach differs from the S&P 500 because
stocks in the S&P 500 are represented in proportion to their market value or
market-capitalization. For example, the 50 largest companies in the S&P 500
represent approximately 60 percent of the S&P 500's value; however, these same
50 companies represent roughly 10 percent of the Fund's value. The Fund may
invest in foreign securities represented in the S&P 500, including depositary
receipts.

EXPENSE EXAMPLE

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments and redemption fees;
and (2) ongoing costs, including advisory fees; distribution and 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 invested at the beginning of the
period and held for the entire period 01/01/06 - 06/30/06.

ACTUAL EXPENSES

The first line of the table below provides information about actual account
values and actual expenses. You may use the information in this line, together
with the amount you invested, to estimate the expenses that you paid over the
period. 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
in the first line 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 second line of the table below provides information about 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. You may use this
information to compare the ongoing cost 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 sales
charges (loads) and redemption fees. Therefore, the second line of the table is
useful in comparing ongoing costs, and will not help you determine the relative
total cost of owning different funds. In addition, if these transactional costs
were included, your costs would have been higher.

NATURE, EXTENT AND QUALITY OF SERVICES

The Board reviewed and considered the nature and extent of the investment
advisory services provided by the Investment Adviser under the Advisory
Agreement, including portfolio management, investment research and equity and
fixed income securities trading. The Board also reviewed and considered the
nature and extent of the non-advisory, administrative services provided by the
Fund's Administrator under the Administration Agreement, including accounting,
clerical, bookkeeping, compliance, business management and planning, and the
provision of supplies, office space and utilities at the Investment Adviser's
expense. (The Investment Adviser and the Administrator together are referred to
as the "Adviser" and the Advisory and Administration Agreements together are
referred to as the "Management Agreement.") The Board also compared the nature
of the services provided by the Adviser with similar services provided by
non-affiliated advisers as reported to the Board by Lipper Inc. ("Lipper").

The Board reviewed and considered the qualifications of the portfolio managers,
the senior administrative managers and other key personnel of the Adviser who
provide the advisory and administrative services to the Fund. The Board
determined that the Adviser's portfolio managers and key personnel are well
qualified by education and/or training and experience to perform the services in
an efficient and professional manner. The Board concluded that the nature and
extent of the advisory and administrative services provided were necessary and
appropriate for the conduct of the business and investment activities of the
Fund. The Board also concluded that the overall quality of the advisory and
administrative services was satisfactory.

PERFORMANCE RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS

On a regular basis, the Board reviews the performance of all funds in the Morgan
Stanley Fund Complex, including the Fund, compared to their peers, paying
specific attention to the underperforming funds. In addition, the Board
specifically reviewed the Fund's performance for the one-, three- and five-year
periods ended November 30, 2005, as shown in a report provided by Lipper (the
"Lipper Report"), compared to the performance of comparable funds selected by
Lipper (the "performance peer group"). The Board also discussed with the Adviser
the performance goals and the actual results achieved in managing the Fund. The
Board concluded that the Fund's performance was competitive with that of its
performance peer group.

FEES RELATIVE TO OTHER PROPRIETARY FUNDS MANAGED BY THE ADVISER WITH COMPARABLE
INVESTMENT STRATEGIES

The Board reviewed the advisory and administrative fee (together, the
"management fee") rate paid by the Fund under the Management Agreement. The
Board noted that the management fee rate was comparable to the management fee
rates charged by the Adviser to other proprietary funds it manages with
investment strategies comparable to those of the Fund.

FEES AND EXPENSES RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS

The Board reviewed the management fee rate and total expense ratio of the Fund
as compared to the average management fee rate and average total expense ratio
for funds, selected by Lipper (the "expense peer group"), managed by other
advisers with investment strategies comparable to those of the Fund, as shown in
the Lipper Report. The Board concluded that the Fund's management fee rate and
total expense ratio were competitive with those of its expense peer group.

BREAKPOINTS AND ECONOMIES OF SCALE

The Board reviewed the structure of the Fund's management fee schedule under the
Management Agreement and noted that it includes breakpoints. The Board also
reviewed the level of the Fund's management fee and noted that the fee, as a
percentage of the Fund's net assets, would decrease as net assets increase
because the management fee includes breakpoints. The Board concluded that the
Fund's management fee would reflect economies of scale as assets increase.

PROFITABILITY OF THE ADVISER AND AFFILIATES

The Board considered information concerning the costs incurred and profits
realized by the Adviser and affiliates during the last year from their
relationship with the Fund and during the last two years from their relationship
with the Morgan Stanley Fund Complex and reviewed with the Adviser the cost
allocation methodology used to determine the profitability of the Adviser and
affiliates. Based on its review of the information it received, the Board
concluded that the profits earned by the Adviser and affiliates were not
excessive in light of the advisory, administrative and other services provided
to the Fund.

FALL-OUT BENEFITS

The Board considered so-called "fall-out benefits" derived by the Adviser and
affiliates from their relationship with the Fund and the Morgan Stanley Fund
Complex, such as sales charges on sales of Class A shares and "float" benefits
derived from handling of checks for purchases and sales of Fund shares, through
a broker-dealer affiliate of the Adviser. The Board also considered that a
broker-dealer affiliate of the Adviser receives from the Fund 12b-1 fees for
distribution and shareholder services. The Board also considered that an
affiliate of the Adviser sold a joint venture that owned an electronic trading
system network ("ECN"), which may be used by the Adviser for trading on behalf
of the Fund. As part of the sale of the joint venture, the affiliate receives a
10-year payout based on the revenue stream from trading on the ECN. Although the
affiliate disgorges the portion of the payout that is comprised of commissions
received from trades executed by the Adviser on the ECN to a charitable
organization, the Board considered the fact that trades by the Adviser would
increase order flow, and, thus, result in a potential fall-out benefit to the
affiliate. The Board concluded that the float benefits were relatively small,
the sales charges and 12b-1 fees were competitive with those of other
broker-dealers, the affiliate disgorged revenues in connection with the
ECN-related revenue and the potential fall-out benefit from increased order flow
was relatively small.

SOFT DOLLAR BENEFITS

The Board considered whether the Adviser realizes any benefits as a result of
brokerage transactions executed through "soft dollar" arrangements. Under such
arrangements, brokerage commissions paid by the Fund and/or other funds managed
by the Adviser would be used to pay for research that a securities broker
obtains from third parties, or to pay for both research and execution services
from securities brokers who effect transactions for the Fund. The Adviser
informed the Board that the Fund's commissions are used to pay for execution
services only.

ADVISER FINANCIALLY SOUND AND FINANCIALLY CAPABLE OF MEETING THE FUND'S NEEDS

The Board considered whether the Adviser is financially sound and has the
resources necessary to perform its obligations under the Management Agreement.
The Board noted that the Adviser's operations remain profitable, although
increased expenses in recent years have reduced the Adviser's profitability. The
Board concluded that the Adviser has the financial resources necessary to
fulfill its obligations under the Management Agreement.

HISTORICAL RELATIONSHIP BETWEEN THE FUND AND THE ADVISER

The Board also reviewed and considered the historical relationship between the
Fund and the Adviser, including the organizational structure of the Adviser, the
policies and procedures formulated and adopted by the Adviser for managing the
Fund's operations and the Board's confidence in the competence and integrity of
the senior managers and key personnel of the Adviser. The Board concluded that
it is beneficial for the Fund to continue its relationship with the Adviser.

OTHER FACTORS AND CURRENT TRENDS

The Board considered the controls and procedures adopted and implemented by the
Adviser and monitored by the Fund's Chief Compliance Officer and concluded that
the conduct of business by the Adviser indicates a good faith effort on its part
to adhere to high ethical standards in the conduct of the Fund's business.

GENERAL CONCLUSION

After considering and weighing all of the above factors, the Board concluded
that it would be in the best interest of the Fund and its shareholders to
approve renewal of the Management Agreement for another year.

MORGAN STANLEY EQUALLY-WEIGHTED S&P 500 FUND
NOTES TO FINANCIAL STATEMENTS - JUNE 30, 2006

1. ORGANIZATION AND ACCOUNTING POLICIES

Morgan Stanley Equally-Weighted S&P 500 Fund (the "Fund") is registered under
the Investment Company Act of 1940, as amended (the "Act"), as a diversified,
open-end management investment company. The Fund's investment objective is to
achieve a high level of total return on its assets through a combination of
capital appreciation and current income. The Fund was organized as a
Massachusetts business trust on May 27, 1987 and commenced operations on
December 1, 1987. On July 28, 1997, the Fund converted to a multiple class share
structure.

The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase and some
Class A shares, and most Class B shares and Class C shares are subject to a
contingent deferred sales charge imposed on shares redeemed within eighteen
months, six years and one year, respectively. Class D shares are not subject to
a sales charge. Additionally, Class A shares, Class B shares and Class C shares
incur distribution expenses.

Effective August 29, 2005, the Board of Trustees of the Fund approved the
implementation of a 2% redemption fee, on Class A shares, Class B shares, Class
C shares, and Class D shares, which is paid directly to the Fund, for shares
redeemed within seven days of purchase, subject to certain exceptions. The
redemption fee is designed to protect the Fund and its remaining shareholders
from the effects of short-term trading.

The following is a summary of significant accounting policies:

A. Valuation of Investments -- (1) an equity portfolio security listed or traded
on the New York Stock Exchange ("NYSE") or American Stock Exchange or other
exchange is valued at its latest sale price prior to the time when assets are
valued; if there were no sales that day, the security is valued at the mean
between the last reported bid and asked price; (2) an equity portfolio security
listed or traded on the Nasdaq is valued at the Nasdaq Official Closing Price;
if there were no sales that day, the security is valued at the mean between the
last reported bid and asked price; (3) all other portfolio securities for which
over-the-counter market quotations are readily available are valued at the mean
between the last reported bid and asked price. In cases where a security is
traded on more than one exchange, the security is valued on the exchange
designated as the primary market; (4) for equity securities traded on foreign
exchanges, the last reported sale price or the latest bid price may be used if
there were no sales on a particular day; (5) futures are valued at the latest
price published by the commodities exchange on which they trade; (6) when market
quotations are not readily available or Morgan Stanley Investment Advisors Inc.
(the "Investment Adviser") determines that the latest sale price, the bid price
or the mean between the last reported bid and asked price do not reflect a
security's market value, portfolio securities are valued at their fair value as
determined in good faith under procedures established by and under the general
supervision of the Fund's Trustees. Occasionally, developments


                                       29

<Page>

affecting the closing prices of securities and other assets may occur between
the times at which valuations of such securities are determined (that is, close
of the foreign market on which the securities trade) and the close of business
on the NYSE. If developments occur during such periods that are expected to
materially affect the value of such securities, such valuations may be adjusted
to reflect the estimated fair value of such securities as of the close of the
NYSE, as determined in good faith by the Fund's Trustees or by the Investment
Adviser using a pricing service and/or procedures approved by the Trustees of
the Fund; and (7) short-term debt securities having a maturity date of more than
sixty days at time of purchase are valued on a mark-to-market basis until sixty
days prior to maturity and thereafter at amortized cost based on their value on
the 61st day. Short-term debt securities having a maturity date of sixty days or
less at the time of purchase are valued at amortized cost.

B. Accounting for Investments -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Dividend income and other distributions are recorded on the ex-dividend date.
Discounts are accreted and premiums are amortized over the life of the
respective securities. Interest income is accrued daily.

C. Repurchase Agreements -- Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Fund, along with other affiliated
entities managed by the Investment Adviser, may transfer uninvested cash
balances into one or more joint repurchase agreement accounts. These balances
are invested in one or more repurchase agreements and are collateralized by
cash, U.S. Treasury or federal agency obligations. The Fund may also invest
directly with institutions in repurchase agreements. The Fund's custodian
receives the collateral, which is marked-to-market daily to determine that the
value of the collateral does not decrease below the repurchase price plus
accrued interest.

D. Multiple Class Allocations -- Investment income, expenses (other than
distribution fees), and realized and unrealized gains and losses are allocated
to each class of shares based upon the relative net asset value on the date such
items are recognized. Distribution fees are charged directly to the respective
class.

E. Futures Contracts -- A futures contract is an agreement between two parties
to buy and sell financial instruments or contracts based on financial indices at
a set price on a future date. Upon entering into such a contract, the Fund is
required to pledge to the broker cash, U.S. Government securities or other
liquid portfolio securities equal to the minimum initial margin requirements of
the applicable futures exchange. Pursuant to the contract, 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 known as
variation margin are recorded by the Fund as unrealized gains and losses. Upon
closing of the contract, the Fund realizes a gain or loss equal to the
difference between the value of the contract at the time it was opened and the
value at the time it was closed.


                                       30

F. Federal Income Tax Policy -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to its
shareholders. Accordingly, no federal income tax provision is required.

G. Dividends and Distributions to Shareholders -- Dividends and distributions to
shareholders are recorded on the ex-dividend date.

H. Use of Estimates -- The preparation of financial statements in accordance
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts and disclosures.
Actual results could differ from those estimates.

2. INVESTMENT ADVISORY/ADMINISTRATION AGREEMENTS

Pursuant to an Investment Advisory Agreement, the Fund pays the Investment
Adviser an advisory fee, accrued daily and payable monthly, by applying the
following annual rates to the net assets of the Fund determined as of the close
of each business day: 0.12% to the portion of the daily net assets not exceeding
$2 billion and 0.10% to the portion of the daily net assets in excess of $2
billion.

Pursuant to an Administration Agreement with Morgan Stanley Services Company
Inc. (the "Administrator"), an affiliate of the Investment Adviser, the Fund
pays an administration fee, accrued daily and payable monthly, by applying the
annual rate of 0.08% to the Fund's daily net assets.

3. PLAN OF DISTRIBUTION

Shares of the Fund are distributed by Morgan Stanley Distributors Inc. (the
"Distributor"), an affiliate of the Investment Adviser and Administrator. The
Fund has adopted a Plan of Distribution (the "Plan") pursuant to Rule 12b-1
under the Act. The Plan provides that the Fund will pay the Distributor a fee
which is accrued daily and paid monthly at the following annual rates: (i) Class
A -- up to 0.25% of the average daily net assets of Class A; (ii) Class B -- up
to 1.0% of the lesser of: (a) the average daily aggregate gross sales of the
Class B shares since the inception of the Fund (not including reinvestment of
dividend or capital gain distributions) less the average daily aggregate net
asset value of the Class B shares redeemed since the Fund's inception upon which
a contingent deferred sales charge has been imposed or waived; or (b) the
average daily net assets of Class B; and (iii) Class C -- up to 1.0% of the
average daily net assets of Class C.

In the case of Class B shares, provided that the Plan continues in effect, any
cumulative expenses incurred by the Distributor but not yet recovered may be
recovered through the payment of future distribution fees from the Fund pursuant
to the Plan and contingent deferred sales charges paid by investors upon
redemption of Class B shares. Although there is no legal obligation for the Fund
to pay expenses incurred in excess of payments made to the Distributor under the
Plan and the proceeds of


                                       31

<Page>

contingent deferred sales charges paid by investors upon redemption of shares,
if for any reason the Plan is terminated, the Trustees will consider at that
time the manner in which to treat such expenses. The Distributor has advised the
Fund that such excess amounts totaled $43,078,334 at June 30, 2006.

In the case of Class A shares and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 1.0% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales credit to Morgan Stanley Financial Advisors or other selected
broker-dealer representatives may be reimbursed in the subsequent calendar year.
For the year ended June 30, 2006, the distribution fee was accrued for Class A
shares and Class C shares at the annual rate of 0.25% and 0.95%, respectively.

The Distributor has informed the Fund that for the year ended June 30, 2006, it
received contingent deferred sales charges from certain redemptions of the
Fund's Class B shares and Class C shares of $1,237,354 and $23,749, respectively
and received $645,343 in front-end sales charges from sales of the Fund's Class
A shares. The respective shareholders pay such charges which are not an expense
of the Fund.

4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES

The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the year ended June 30, 2006 aggregated $331,305,426
and $416,094,120, respectively. Included in the aforementioned are purchases and
sales of Morgan Stanley common stock, an affiliate of the Investment Adviser,
Administrator and Distributor, of $82,672 and $275,584, respectively, including
a net realized gain of $4,770.

Morgan Stanley Trust, an affiliate of the Investment Adviser, Administrator and
Distributor, is the Fund's transfer agent.

The Fund has an unfunded noncontributory defined benefit pension plan covering
certain independent Trustees of the Fund who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on factors which include years of service and compensation. The
Trustees voted to close the plan to new participants and eliminate the future
benefits growth due to increases to compensation after July 31, 2003. Aggregate
pension costs for the year ended June 30, 2006 included in Trustees' fees and
expenses in the Statement of Operations amounted to $9,256. At June 30, 2006,
the Fund had an accrued pension liability of $74,869 which is included in
accrued expenses in the Statement of Assets and Liabilities.

The Fund has an unfunded Deferred Compensation Plan (the "Compensation Plan")
which allows each independent Trustee to defer payment of all, or a portion, of
the fees he receives for serving on the


                                       32

<Page>

Board of Trustees. Each eligible Trustee generally may elect to have the
deferred amounts credited with a return equal to the total return on one or more
of the Morgan Stanley funds that are offered as investment options under the
Compensation Plan. Appreciation/depreciation and distributions received from
these investments are recorded with an offsetting increase/decrease in the
deferred compensation obligation and do not affect the net asset value of the
Fund.

6. EXPENSE OFFSET

The expense offset represents a reduction of the transfer agent fees and
expenses for earnings on cash balances maintained by the Fund.

7. FEDERAL INCOME TAX STATUS

The amount of dividends and distributions from net investment income and net
realized capital gains are determined in accordance with federal income tax
regulations which may differ from generally accepted accounting principles.
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. Dividends and
distributions which exceed net investment income and net realized capital gains
for tax purposes are reported as distributions of paid-in-capital.

The tax character of distributions paid was as follows:

                                 FOR THE YEAR    FOR THE YEAR
                                    ENDED           ENDED
                                JUNE 30, 2006   JUNE 30, 2005
                                -------------   -------------
Ordinary income                  $28,038,777     $17,307,953
Long-term capital gains           56,901,078      18,331,199
                                 -----------     -----------
Total distributions              $84,939,855     $35,639,152
                                 ===========     ===========

As of June 30, 2006, the tax-basis components of accumulated earnings were as
follows:

Undistributed ordinary income    $ 19,748,731
Undistributed long-term gains      78,023,542
                                 ------------
Net accumulated earnings           97,772,273
Temporary differences                 (78,164)
Net unrealized appreciation       826,838,657
                                 ------------
Total accumulated earnings       $924,532,766
                                 ============

As of June 30, 2006, the Fund had temporary book/tax differences primarily
attributable to capital loss deferrals on wash sales, mark-to-market of open
futures contracts and tax adjustments on real estate investment trusts ("REITs")
held by the Fund and permanent book/tax differences attributable to tax
adjustments on REITs sold by the Fund. To reflect reclassifications arising from
the permanent differences, accumulated undistributed net investment income was
charged and accumulated undistributed net realized gain was credited $713,834.

8. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS

The Fund may purchase and sell stock index futures ("futures contracts") for the
following reasons: to simulate full investment in the S&P 500 Index while
retaining a cash balance for fund management purposes; to facilitate trading; to
reduce transaction costs; or to seek higher investment returns when a futures
contract is priced more attractively than stocks comprising the S&P 500 Index.


                                       34

<Page>

These futures contracts involve elements of market risk in excess of the amount
reflected in the Statement of Assets and Liabilities. The Fund bears the risk of
an unfavorable change in the value of the underlying securities. Risks may also
arise upon entering into these contracts from the potential inability of the
counterparties to meet the terms of their contracts.

9. LEGAL MATTERS

The Investment Adviser, certain affiliates of the Investment Adviser, certain
officers of such affiliates and certain investment companies advised by the
Investment Adviser or its affiliates, including the Fund, are named as
defendants in a consolidated class action. This consolidated action also names
as defendants certain individual Trustees and Directors of the Morgan Stanley
funds. The consolidated amended complaint, filed in the United States District
Court Southern District of New York on April 16, 2004, generally alleges that
defendants, including the Fund, violated their statutory disclosure obligations
and fiduciary duties by failing properly to disclose (i) that the Investment
Adviser and certain affiliates of the Investment Adviser allegedly offered
economic incentives to brokers and others to recommend the funds advised by the
Investment Adviser or its affiliates to investors rather than funds managed by
other companies, and (ii) that the funds advised by the Investment Adviser or
its affiliates, including the Fund, allegedly paid excessive commissions to
brokers in return for their efforts to recommend these funds to investors. The
complaint seeks, among other things, unspecified compensatory damages,
rescissionary damages, fees and costs. The defendants have moved to dismiss the
action. On March 9, 2005, Plaintiffs sought leave to supplement their complaint
to assert claims on behalf of other investors, which motion defendants opposed.
On April 14, 2006, the Court granted defendants' motion to dismiss in its
entirety. Additionally, the Court denied Plaintiff's motion to supplement their
complaint. This matter is now concluded.

10. NEW ACCOUNTING PRONOUNCEMENT

In July 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation 48, Accounting for Uncertainty in Income Taxes -- an
interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting
for income taxes by prescribing the minimum recognition threshold a tax position
must meet before being recognized in the financial statements. FIN 48 is
effective for fiscal years beginning after December 15, 2006. The Fund will
adopt FIN 48 during 2007 and the impact to the Fund's financial statements, if
any, is currently being assessed.

MORGAN STANLEY EQUALLY-WEIGHTED S&P 500 FUND

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees of
Morgan Stanley Equally-Weighted S&P 500 Fund:

We have audited the accompanying statement of assets and liabilities of Morgan
Stanley Equally-Weighted S&P 500 Fund (the "Fund"), including the portfolio of
investments, as of June 30, 2006, and the related statements of operations for
the year then ended and changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

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. The Fund
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of June 30, 2006, by correspondence with the custodian
and brokers. 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 Morgan
Stanley Equally-Weighted S&P 500 Fund as of June 30, 2006, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the five years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

                  MORGAN STANLEY RETAIL AND INSTITUTIONAL FUNDS

                    AS ADOPTED AND AMENDED JULY 23, 2004,(1)

     1. STATEMENT OF PRINCIPLES

The Audit Committee of the Board is required to review and, in its sole
discretion, pre-approve all Covered Services to be provided by the Independent
Auditors to the Fund and Covered Entities in order to assure that services
performed by the Independent Auditors do not impair the auditor's independence
from the Fund.

The SEC has issued rules specifying the types of services that an independent
auditor may not provide to its audit client, as well as the audit committee's
administration of the engagement of the independent auditor. The SEC's rules
establish two different approaches to pre-approving services, which the SEC
considers to be equally valid. Proposed services either: may be pre-approved
without consideration of specific case-by-case services by the Audit Committee
("GENERAL PRE-APPROVAL"); or require the specific pre-approval of the Audit
Committee or its delegate ("SPECIFIC PRE-APPROVAL"). The Audit Committee
believes that the combination of these two approaches in this Policy will result
in an effective and efficient procedure to pre-approve services performed by the
Independent Auditors. As set forth in this Policy, unless a type of service has
received general pre-approval, it will require specific pre-approval by the
Audit Committee (or by any member of the Audit Committee to which pre-approval
authority has been delegated) if it is to be provided by the Independent
Auditors. Any proposed services exceeding pre-approved cost levels or budgeted
amounts will also require specific pre-approval by the Audit Committee.

The appendices to this Policy describe the Audit, Audit-related, Tax and All
Other services that have the general pre-approval of the Audit Committee. The
term of any general pre-approval is 12 months from the date of pre-approval,
unless the Audit Committee considers and provides a different period and states
otherwise. The Audit Committee will annually review and pre-approve the services
that may be provided by the Independent Auditors without obtaining specific
pre-approval from the Audit

- ----------
(1)  This Audit Committee Audit and Non-Audit Services Pre-Approval Policy and
     Procedures (the "POLICY"), adopted as of the date above, supersedes and
     replaces all prior versions that may have been adopted from time to time.

<Page>

Committee. The Audit Committee will add to or subtract from the list of general
pre-approved services from time to time, based on subsequent determinations.

The purpose of this Policy is to set forth the policy and procedures by which
the Audit Committee intends to fulfill its responsibilities. It does not
delegate the Audit Committee's responsibilities to pre-approve services
performed by the Independent Auditors to management.

The Fund's Independent Auditors have reviewed this Policy and believes that
implementation of the Policy will not adversely affect the Independent Auditors'
independence.

     2. DELEGATION

As provided in the Act and the SEC's rules, the Audit Committee may delegate
either type of pre-approval authority to one or more of its members. The member
to whom such authority is delegated must report, for informational purposes
only, any pre-approval decisions to the Audit Committee at its next scheduled
meeting.

     3. AUDIT SERVICES

The annual Audit services engagement terms and fees are subject to the specific
pre-approval of the Audit Committee. Audit services include the annual financial
statement audit and other procedures required to be performed by the Independent
Auditors to be able to form an opinion on the Fund's financial statements. These
other procedures include information systems and procedural reviews and testing
performed in order to understand and place reliance on the systems of internal
control, and consultations relating to the audit. The Audit Committee will
approve, if necessary, any changes in terms, conditions and fees resulting from
changes in audit scope, Fund structure or other items.

In addition to the annual Audit services engagement approved by the Audit
Committee, the Audit Committee may grant general pre-approval to other Audit
services, which are those services that only the Independent Auditors reasonably
can provide. Other Audit services may include statutory audits and services
associated with SEC registration statements (on Forms N-1A, N-2, N-3, N-4,
etc.), periodic reports and other documents filed with the SEC or other
documents issued in connection with securities offerings.

The Audit Committee has pre-approved the Audit services in Appendix B.1. All
other Audit services not listed in Appendix B.1 must be specifically
pre-approved by the Audit Committee (or by any member of the Audit Committee to
which pre-approval has been delegated).

     4. AUDIT-RELATED SERVICES

Audit-related services are assurance and related services that are reasonably
related to the performance of the audit or review of the Fund's financial
statements and, to the extent they are Covered Services, the Covered Entities or
that are traditionally performed by the Independent Auditors. Because the Audit
Committee believes that the provision of Audit-related services does not impair
the independence of the auditor and is consistent with the SEC's rules on
auditor independence, the Audit Committee may grant general

<Page>

pre-approval to Audit-related services. Audit-related services include, among
others, accounting consultations related to accounting, financial reporting or
disclosure matters not classified as "Audit services"; assistance with
understanding and implementing new accounting and financial reporting guidance
from rulemaking authorities; agreed-upon or expanded audit procedures related to
accounting and/or billing records required to respond to or comply with
financial, accounting or regulatory reporting matters; and assistance with
internal control reporting requirements under Forms N-SAR and/or N-CSR.

The Audit Committee has pre-approved the Audit-related services in Appendix B.2.
All other Audit-related services not listed in Appendix B.2 must be specifically
pre-approved by the Audit Committee (or by any member of the Audit Committee to
which pre-approval has been delegated).

     5. TAX SERVICES

The Audit Committee believes that the Independent Auditors can provide Tax
services to the Fund and, to the extent they are Covered Services, the Covered
Entities, such as tax compliance, tax planning and tax advice without impairing
the auditor's independence, and the SEC has stated that the Independent Auditors
may provide such services.

Pursuant to the preceding paragraph, the Audit Committee has pre-approved the
Tax Services in Appendix B.3. All Tax services in Appendix B.3 must be
specifically pre-approved by the Audit Committee (or by any member of the Audit
Committee to which pre-approval has been delegated).

     6. ALL OTHER SERVICES

The Audit Committee believes, based on the SEC's rules prohibiting the
Independent Auditors from providing specific non-audit services, that other
types of non-audit services are permitted. Accordingly, the Audit Committee
believes it may grant general pre-approval to those permissible non-audit
services classified as All Other services that it believes are routine and
recurring services, would not impair the independence of the auditor and are
consistent with the SEC's rules on auditor independence.

The Audit Committee has pre-approved the All Other services in Appendix B.4.
Permissible All Other services not listed in Appendix B.4 must be specifically
pre-approved by the Audit Committee (or by any member of the Audit Committee to
which pre-approval has been delegated).

     7. PRE-APPROVAL FEE LEVELS OR BUDGETED AMOUNTS

Pre-approval fee levels or budgeted amounts for all services to be provided by
the Independent Auditors will be established annually by the Audit Committee.
Any proposed services exceeding these levels or amounts will require specific
pre-approval by the Audit Committee. The Audit Committee is mindful of the
overall relationship of fees for audit and non-audit services in determining
whether to pre-approve any such services.

     8. PROCEDURES

<Page>

All requests or applications for services to be provided by the Independent
Auditors that do not require specific approval by the Audit Committee will be
submitted to the Fund's Chief Financial Officer and must include a detailed
description of the services to be rendered. The Fund's Chief Financial Officer
will determine whether such services are included within the list of services
that have received the general pre-approval of the Audit Committee. The Audit
Committee will be informed on a timely basis of any such services rendered by
the Independent Auditors. Requests or applications to provide services that
require specific approval by the Audit Committee will be submitted to the Audit
Committee by both the Independent Auditors and the Fund's Chief Financial
Officer, and must include a joint statement as to whether, in their view, the
request or application is consistent with the SEC's rules on auditor
independence.

The Audit Committee has designated the Fund's Chief Financial Officer to monitor
the performance of all services provided by the Independent Auditors and to
determine whether such services are in compliance with this Policy. The Fund's
Chief Financial Officer will report to the Audit Committee on a periodic basis
on the results of its monitoring. Both the Fund's Chief Financial Officer and
management will immediately report to the chairman of the Audit Committee any
breach of this Policy that comes to the attention of the Fund's Chief Financial
Officer or any member of management.

     9. ADDITIONAL REQUIREMENTS

The Audit Committee has determined to take additional measures on an annual
basis to meet its responsibility to oversee the work of the Independent Auditors
and to assure the auditor's independence from the Fund, such as reviewing a
formal written statement from the Independent Auditors delineating all
relationships between the Independent Auditors and the Fund, consistent with
Independence Standards Board No. 1, and discussing with the Independent Auditors
its methods and procedures for ensuring independence.
