MARKET CONDITIONS

For the 12-month period ended September 30, 2006, U.S. equity markets posted
broadly positive returns. The S&P 500(R) returned 10.79 percent, including
dividends. After many years of outperformance, small- and mid-cap equity indexes
lagged their large-cap counterparts. The technology-sensitive Nasdaq-100 Index
lagged other broad equity market measures, with a modestly positive return over
the period.

Although all S&P 500 sectors posted positive returns over the 12-month period,
telecommunication services was by far the strongest large-cap sector, gaining
26.05 percent. Despite rising interest rates, financial services also posted
strong returns, advancing 20.53 percent. The sector's strength can largely be
attributed to phenomenal performance by both the real estate and diversified
financials sub-sectors. Information technology produced the weakest sector
returns over the period. Dragged down by semiconductors, technology hardware and
equipment, and software and services, the sector returned a modest 3.26 percent.

After several years of outperformance, the energy sector struggled over the
period. The price of crude oil surged to a new all-time high of $77.23 per
barrel in the second week of July, ahead of the hurricane season. As storm
season passed with relatively little incident, oil prices fell precipitously
through the balance of the period. Energy stocks struggled against falling oil
prices through the last quarter of the period, and the sector advanced only 3.51
percent over the 12-month period.

In response to strong economic fundamentals, the Federal Open Market Committee
(the "Fed") raised rates six times over the period. Cooling commodity prices and
moderating economic growth in the last quarter of the period led the Fed to
pause its monetary tightening over the final two meetings of the period. As of
September 30, 2006, the target federal funds rate was 5.25 percent.

PERFORMANCE ANALYSIS

Morgan Stanley Multi-Asset Class Fund underperformed the S&P 500(R) and the
Lipper Flexible Portfolio Funds Index for the 12 months ended September 30,
2006, assuming no deduction of applicable sales charges.

Although the Fund made several tactical moves, it nonetheless retained a high
allocation to the information technology sector over the period through
positions in both the Technology Fund and the Nasdaq-100 Index Fund. As
technology stocks struggled throughout the period, the Fund's performance was
adversely affected


                                        2

<Page>

by these allocations. A relative underweight in the financial services sector to
the S&P 500, contributed to underperformance. Partly based on management's
belief that rising interest rates would create a difficult environment for
financial services, the Fund maintained small allocations to both the Financial
Services Trust and the Real Estate Fund.

Entering into the early summer equity market correction, the Fund significantly
reduced its allocation to high beta and small-cap sensitive funds. (Beta is a
measure of price volatility relative to the broad market's movements. The higher
the beta, the more volatile a stock's or fund's price movement.) Specifically,
the Fund reduced its allocation to technology-oriented funds such as the
Nasdaq-100 Index Fund and the small-cap Special Growth Fund. The proceeds from
the sales of market-sensitive funds were held in cash for the duration of the
volatile summer period. As markets began to recover, the Fund reinvested its
cash across a wide range of underlying funds.

Over the latter half of the period, the Fund began to assume a less aggressive
market posture and reallocated to more defensive sectors and funds. Although the
Fund maintained a clear bias toward equities over the period, the Fund began
gradually to increase its investments in both the Convertible Securities Trust
and the U.S. Government Securities Trust. Based on the belief that the
seven-year period of small- and mid-cap outperformance was approaching an end,
the Fund gradually reduced its exposure to small- and mid-cap funds during the
year. Specifically, the Fund reduced its allocation to the Special Value Fund,
the Special Growth Fund, and the Equally-Weighted S&P 500 Fund.

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 NORMALLY INVESTS AT LEAST 80 PERCENT OF ITS ASSETS IN SHARES OF
AFFILIATED MUTUAL FUNDS ("UNDERLYING FUNDS"). IN DECIDING HOW TO ALLOCATE FUND
ASSETS AMONG UNDERLYING FUNDS, THE FUND'S "INVESTMENT ADVISER," MORGAN STANLEY
INVESTMENT ADVISORS INC., CONSIDERS ITS OUTLOOK FOR THE U.S. AND GLOBAL
ECONOMIES AND FINANCIAL MARKETS AND THE RELATIVE MARKET VALUATIONS OF THE
UNDERLYING FUNDS. THE FUND NORMALLY EXPECTS TO INVEST BETWEEN 50 PERCENT AND 100
PERCENT OF ITS NET ASSETS IN UNDERLYING FUNDS WHICH INVEST PRIMARILY IN U.S.
EQUITY SECURITIES, BETWEEN 0 PERCENT AND 50 PERCENT OF ITS NET ASSETS IN
UNDERLYING FUNDS WHICH INVEST PRIMARILY IN NON-U.S. EQUITY SECURITIES AND
BETWEEN 0 PERCENT AND 50 PERCENT OF ITS NET ASSETS IN UNDERLYING FUNDS WHICH
INVEST PRIMARILY IN FIXED INCOME SECURITIES. THE INVESTMENT ADVISER THEN
DETERMINES THE COMBINATION OF UNDERLYING FUNDS THAT IT BELIEVES BEST REPRESENTS
THE SELECTED ASSET ALLOCATION STRATEGY. THE INVESTMENT ADVISER CONTINUOUSLY
MONITORS THE FUND'S ASSET ALLOCATION STRATEGY AND THE SELECTION OF INDIVIDUAL
UNDERLYING FUNDS AND MAY MAKE ADJUSTMENTS TO BOTH AS MARKET CHANGES WARRANT. THE
FUND GENERALLY SELLS THE SECURITIES OF AN UNDERLYING FUND WHEN SUCH UNDERLYING
FUND IS NO LONGER REPRESENTATIVE OF THE SELECTED ASSET ALLOCATION STRATEGY.
THERE ARE NO MINIMUM OR MAXIMUM PERCENTAGES IN WHICH THE FUND MUST INVEST IN ANY
UNDERLYING FUND. THE INVESTMENT ADVISER FOR EACH UNDERLYING FUND IS RESPONSIBLE
FOR DECIDING WHICH SECURITIES TO PURCHASE AND SELL FOR EACH RESPECTIVE
UNDERLYING FUND. FOR MORE INFORMATION ABOUT THE UNDERLYING FUNDS, SEE "FUND
MANAGEMENT --MANAGEMENT OF THE UNDERLYING FUNDS" IN THE FUND'S PROSPECTUS. IN
ADDITION, THE FUND MAY INVEST UP TO 20 PERCENT OF ITS ASSETS DIRECTLY IN
GOVERNMENT SECURITIES AND CASH EQUIVALENTS WHEN THE INVESTMENT ADVISER BELIEVES
MARKET CONDITIONS SO WARRANT.

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 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 04/01/06 - 09/30/06.

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.

INVESTMENT ADVISORY AGREEMENT APPROVAL

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 noted that the Adviser did not manage any other proprietary funds with
investment strategies comparable to those of the Fund.

FEES AND EXPENSES RELATIVE TO COMPARABLE FUNDS MANAGED BY OTHER ADVISERS

The Board reviewed the advisory and administrative fee (together, the
"management fee") rate paid by the Fund under the Management Agreement and the
total expense ratio of the Fund. The Board noted that the Fund was not


                                        9

<Page>

paying any management fee and did not incur expenses, other than brokerage and
12b-1 fees, during the periods measured in the Lipper Report since the Adviser
had agreed to waive all fees and assume all expenses, excluding brokerage and
12b-1 fees, until April 30, 2007. The Board concluded that the management fee
rate and total expense ratio were satisfactory at the present time.

BREAKPOINTS AND ECONOMIES OF SCALE

The Board noted that the Adviser does not receive a management fee from the
Fund.

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 "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
concluded that the float benefits were relatively small and the 12b-1 fees were
competitive with those of other broker-dealers.

SOFT DOLLAR BENEFITS

The Board considered whether the Adviser realizes any benefits from commissions
paid to brokers who execute securities transactions for the Fund ("soft
dollars"). The Board noted that the Fund invests only in other Morgan Stanley
funds and fixed income securities, which do not generate soft dollars.

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.


                                       10

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 Multi-Asset Class Fund
NOTES TO FINANCIAL STATEMENTS - SEPTEMBER 30, 2006

1. Organization and Accounting Policies

Morgan Stanley Multi-Asset Class Fund (the "Fund") is registered under the
Investment Company Act of 1940, as amended (the "Act"), as a non-diversified,
open-end management investment company. The Fund will invest in Class D shares
of other open-end management investment companies that are either members of the
Morgan Stanley Family of Funds or managed by an investment advisor that is an
affiliate of Morgan Stanley Investment Advisors, Inc. (the "Investment Adviser")
(individually, an "Underlying Fund" and collectively, the "Underlying Funds").
The Fund's investment objective is to maximize total investment return. The Fund
was organized as a Massachusetts business trust on July 3, 1997 and commenced
operations on November 25, 1997.

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.

The following is a summary of significant accounting policies:

A. Valuation of Investments -- (1) Investments are valued at the net asset value
per share of each Underlying Fund determined as of the close of the New York
Stock Exchange on valuation date; and (2) 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.


                                       17

<Page>

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. 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.

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

G. 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 no investment
advisory fee. However, the Fund, through its investments in the Underlying
Funds, will pay its pro rata share of the advisory or sub-advisory fees to the
Investment Adviser and/or Sub-Advisers of the Underlying Funds.

Pursuant to an Administration Agreement with Morgan Stanley Services Company
Inc. (the "Administrator"), an affiliate of the Investment Adviser, the Fund
pays no administration fee. However, the Fund through its investments in the
Underlying Funds, will pay its pro rata share of the administration fee to the
Administrator.

The Investment Adviser agreed to assume all operating expenses (except for
distribution fees) until April 30, 2007. At September 30, 2006, included in the
Statements of Assets and Liabilities are receivables from an affiliate which
represent expense reimbursements due to the Fund.

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 average daily net assets of Class B; and (iii) Class C -- up to
1.0% of the average daily net assets of Class C.


                                       18

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 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 $3,543,551
at September 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 and other authorized
financial representatives at the time of sale may be reimbursed in the
subsequent calendar year. For the year ended September 30, 2006, the
distribution fee was accrued for Class A shares and Class C shares at the annual
rate of 0.24% and 0.97%, respectively.

The Distributor has informed the Fund that for the year ended September 30,
2006, it received contingent deferred sales charges from certain redemptions of
the Fund's Class A shares, Class B shares and Class C shares of $758, $60,247
and $992, respectively and received $16,183 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 September 30, 2006 aggregated
$31,861,144 and $38,441,611, respectively.

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

The Fund began 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 or she receives for serving on the 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.

5. Expense Offset

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

6. 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:

                                    ==========            ========

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

Undistributed ordinary income       $  325,635
Undistributed long-term gains        1,750,578
                                    ----------
Net accumulated earnings             2,076,213
Net unrealized appreciation          1,419,947
                                    ----------
Total accumulated earnings          $3,496,160
                                    ==========

During the year ended September 30, 2006, the Fund utilized its net capital loss
carryforward of $5,710,107.

As of September 30, 2006, the Fund had temporary book/tax differences
attributable to capital loss deferrals on wash sales and permanent book/tax
differences attributable to recharacterization of distributions received from an
Underlying Fund. To reflect reclassifications arising from the permanent
differences, accumulated undistributed net investment income was charged and
accumulated undistributed net realized gain was credited $6,166.

8. 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, were named as
defendants in a consolidated class action. This consolidated action also named
as defendants certain individual Trustees and Directors of the Morgan Stanley
funds. The consolidated amended complaint, filed in the United States District
Court for the Southern District of New York on April 16, 2004, generally alleged
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,


                                       21

<Page>

including the Fund, allegedly paid excessive commissions to brokers in return
for their alleged efforts to recommend these funds to investors. The complaint
sought, among other things, unspecified compensatory damages, rescissionary
damages, fees and costs. On July 2, 2004, defendants moved to dismiss the
action. On March 9, 2005, plaintiffs filed a Motion for Leave to File a
Supplemental Pleading that would, among other things, expand the allegations and
alleged class. On April 14, 2006, the Court granted defendants' motion to
dismiss in its entirety, with prejudice. Additionally, plaintiffs' Motion for
Leave to File a Supplemental Pleading was denied. The time for plaintiffs to
appeal the orders granting defendants' motion to dismiss and denying plaintiffs'
motion for supplemental pleading has expired. This case is now concluded.

9. New Accounting Pronouncements

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 for the fiscal year ending 2008 and the impact to the Fund's
financial statements, if any, is currently being assessed.

In addition, in September 2006, Statement of Financial Accounting Standards No.
157, FAIR VALUE MEASUREMENTS (SFAS 157), was issued and is effective for fiscal
years beginning after November 15, 2007. SFAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the impact the
adoption of SFAS 157 will have on the Fund's financial statement disclosures.

Morgan Stanley Multi-Asset Class Fund
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees of
Morgan Stanley Multi-Asset Class Fund:

We have audited the accompanying statement of assets and liabilities of Morgan
Stanley Multi-Asset Class Fund (the "Fund"), including the portfolio of
investments, as of September 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 September 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 Multi-Asset Class Fund as of September 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.

                                 AUDIT COMMITTEE

                                     OF THE
                  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 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.

- ----------
(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>

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 pre-approval to
Audit-related services. Audit-related services include, among others, accounting
consultations related to accounting, financial reporting or disclosure matters

<Page>

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

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

<Page>

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.

     10.  COVERED ENTITIES

Covered Entities include the Fund's investment adviser(s) and any entity
controlling, controlled by or under common control with the Fund's investment
adviser(s) that provides ongoing services to the Fund(s). Beginning with
non-audit service contracts entered into on or after May 6, 2003, the Fund's
audit committee must pre-approve non-audit services provided not only to the
Fund but also to the Covered Entities if the engagements relate directly to the
operations and financial reporting of the Fund. This list of Covered Entities
would include:
