A Letter From the President

Dear Shareholder

Amid what we've coined a "muddle through" year for the financial markets, the
major benchmark indexes managed to post positive results for the current
reporting period:

Since June 2004, the Federal Reserve Board (the Fed) has tirelessly advanced its
interest rate hiking program, raising the federal funds rate 11 times to 3.75%
by period-end. The Fed admittedly remains more concerned about inflation than
slowing economic growth, causing some to worry that the central bank may
overreact to inflation and increase interest rates more than is necessary to
maintain a healthy economic balance. Recent disruptions to production and
spending from Hurricanes Katrina and Rita are likely to distort the economic
data in the short term, muddying the underlying trends. However, any
hurricane-induced slowdown is likely to be short lived, and the fiscal stimulus
associated with reconstruction efforts in the Gulf could add to gross domestic
product growth in 2006.

U.S. equities exhibited resilience over the past several months as investors
generally tended to proceed with caution. After a strong finish to 2004, the S&P
500 Index remained largely range-bound in 2005, with the last three months
representing the best quarter of the year. Up to this point, strong corporate
earnings reports and low long-term bond yields have worked in favor of equities.
Looking ahead, high energy prices, continued interest rate hikes, a potential
consumer slowdown and/or disappointing earnings pose the greatest risks to U.S.
stocks. Internationally, many markets have benefited from strong economic
statistics, trade surpluses and solid finances.

In the bond market, the yield curve continued to flatten as short-term interest
rates moved in concert with the Fed rate hikes and longer-term interest rates
remained more constant or declined. The difference between two-year and 10-year
Treasury yields collapsed from 151 basis points (1.51%) on September 30, 2004 to
70 basis points on March 31, 2005, to just 16 basis points at period-end.

Financial markets are likely to face continued crosscurrents in the months
ahead. Nevertheless, opportunities do exist and we encourage you to work with
your financial advisor to diversify your portfolio among a variety of asset
types. This can help to diffuse risk while also tapping into the potential
benefits of a broader range of investment alternatives. As always, we thank you
for trusting Merrill Lynch Investment Managers with your investment assets, and
we look forward to serving you in the months and years ahead.

                                 Sincerely,


                                 /s/ Robert C. Doll, Jr.

                                 Robert C. Doll, Jr.

                 CMA MONEY FUND           SEPTEMBER 30, 2005                   3


A Discussion With Your Fund's Portfolio Manager

      We maintained a relatively conservative approach for much of the period as
the Fed continued to increase short-term interest rates, but began to see
greater yield and capital appreciation potential in the two-year sector by
period-end.

How did the Fund perform during the period in light of the existing market
conditions?

For the six-month period ended September 30, 2005, CMA Money Fund paid
shareholders a net annualized dividend of 2.66%. The Fund's seven-day yield as
of September 30, 2005 was 3.10%.

The average portfolio maturity of CMA Money Fund at September 30, 2005 was 60
days, unchanged from March 31, 2005. However, the average portfolio maturity
ranged from a high of 68 days to a low of 53 days during the semi-annual period.

During the past six months, economic growth remained solid albeit slightly
slower than that of 2004 and the first quarter of 2005. The economy grew at an
annualized rate of 3.3% in the second quarter, a pace that, according to the
Federal Reserve Board (the Fed), still warranted removal of "accommodative"
monetary policy. Thus, the Fed continued its "measured" series of interest rate
hikes with quarter-point moves at the May, June, August and September Federal
Open Market Committee meetings. This brought the federal funds rate to 3.75% at
period-end.

Oil remained a hot topic throughout the period, although there was often
disagreement among market participants as to whether a $20-per-barrel increase
in the price of oil posed a greater risk of inflation or a greater threat to
consumer spending. Consumer sentiment figures grew weaker as oil prices rose,
but Fed officials consistently warned that higher crude prices were sure to
result in pricing pressures. This supported their rate increases over the past
six months, which were accompanied by clear indications that the Fed intends to
continue raising interest rates through the remainder of 2005. Short-term yields
climbed in accordance with the Fed's moves while long-term yields actually fell.
Over the past six months, the two-year Treasury yield rose from 3.80% to 4.18%
as the 10-year Treasury yield fell from 4.50% to 4.34%. This resulted in a
flattening of the yield curve, a typical phenomenon in rising interest rate
environments.

Despite this dynamic, the steepness of the yield curve in the front end offered
enticing value. The greatest value seemed to be in the six-month, nine-month and
12-month sectors. We were able to add higher yields to the portfolio while still
maintaining a relatively short average duration. This allowed us to be
constructive while minimizing our interest rate exposure, an approach we thought
was prudent given the likelihood of additional rate hikes.

How did you manage the portfolio during the period?

Early in the period, our investment strategy was formulated on the premise that
the federal funds target would ultimately reach 4%. We then searched for sectors
that were attractively priced given that view. The two-year sector was quite
expensive in our estimation, while shorter sectors such as six and 12 months
offered much greater value. At June 30, 2005, the mid-point of the period, the
two-year Treasury yielded 3.66%, while the six-month London InterBank Offered
Rate (LIBOR) was 3.71% and 12-month LIBOR was 3.90%. Given our view that
interest rates were headed higher, being able to capture higher yields in
shorter-dated maturities was a fairly straightforward decision.

Our efforts were concentrated on these sectors for a majority of the time, while
we continued to target an average portfolio duration in the somewhat
conservative 60-day range. In terms of security selection, spreads on variable
rate product were extremely expensive in our judgment. This was a result of
increased demand but, even more so, was due to a slowdown in agency issuance.
New regulations forced the Federal National Mortgage Association (Fannie Mae) to
reduce its balance sheet. The fewer mortgages Fannie was permitted to own, the
less borrowing it needed to do in order to fund its holdings. Thus, discount
notes outstanding, which had been the agencies' primary tool of short-term
issuance, dipped by $125 billion over the past six months. With all of this
supply now missing from the market, spreads on short-term agency debt collapsed.
Notably, variable rate debt, which once had spreads as wide as LIBOR minus four
basis points, were now trading at LIBOR minus 11 basis points. This, in turn,
tightened spreads on bank and corporate names as well, leaving us with little
interest in the variable rate arena. Moreover, our holdings of variable rate
securities dropped from a high of 67% of the portfolio's net assets in late
April, to 38% by the end of September. These assets were reallocated mostly to
short-dated commercial paper and certificates of deposit. This allowed us to
maintain a shorter average duration and sustain ample liquidity. Having
significant overnight positions in a rising rate environment proves beneficial
because it is the most effective way to meet redemptions while also


4                CMA MONEY FUND           SEPTEMBER 30, 2005


allowing us to capitalize immediately when the Fed raises interest rates.

How would you characterize the portfolio's position at the close of the period?

As long as the Fed considers its monetary policy "accommodative," we intend to
proceed as if the central bank will continue to raise the federal funds target
until it reaches a level deemed to be neutral. Although Hurricanes Katrina and
Rita seemed to pose a legitimate threat to economic growth, the fixed income
markets dismissed this as merely a temporary shock. It seems the economy is
strong enough to absorb a brief slowdown, and that lofty oil prices and the
rebuilding efforts in the Gulf may justify even higher rates.

Nonetheless, after 11 interest rate increases over 16 months, we believe that
the tightening cycle may be completed by the first quarter of 2006. Once the Fed
has communicated to the markets that neutral policy has been achieved, we would
expect the spread between the federal funds rate and the two-year Treasury
yield, which is typically positively sloped, to invert. That being said, at this
time, we are beginning to favor the longer sectors of our market. We believe the
two-year sector currently offers the greatest value from both a yield and
capital appreciation perspective. Yields exceeding 4.75% are currently
available, providing substantial protection against several more rate increases.
We recently increased our average duration target modestly to the 65-day range,
believing that home heating costs, when combined with already high gas prices,
may substantially impact consumer spending in the fourth quarter.

The portfolio's composition, as a percent of net assets, at the end of September
and as of our last report to shareholders is detailed below:

Disclosure of Expenses

Shareholders of this Fund may incur the following charges: (a) expenses related
to transactions, including sales charges, redemption fees and exchange fees; and
(b) operating expenses, including advisory fees, distribution fees including
12(b)-1 fees, and other Fund expenses. The following example (which is based on
a hypothetical investment of $1,000 invested on April 1, 2005 and held through
September 30, 2005) is intended to assist shareholders both in calculating
expenses based on an investment in the Fund and in comparing these expenses with
similar costs of investing in other mutual funds.

The first table below provides information about actual account values and
actual expenses. In order to estimate the expenses a shareholder paid during the
period covered by this report, shareholders can divide their account value by
$1,000 and then multiply the result by the number in the first line under the
heading entitled "Expenses Paid During the Period."

The second table below provides 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. In order to assist
shareholders in comparing the ongoing expenses of investing in this Fund and
other funds, compare the 5% hypothetical example with the 5% hypothetical
examples that appear in other funds' shareholder reports.

The expenses shown in the table are intended to highlight shareholders ongoing
costs only and do not reflect any transactional expenses, such as sales charges,
redemption fees, or exchange fees. Therefore, the second table is useful in
comparing ongoing expenses only, and will not help shareholders determine the
relative total expenses of owning different funds. If these transactional
expenses were included, shareholder expenses would have been higher.

*     Expenses are equal to the Fund's annualized expense ratio of .57%,
      multiplied by the average account value over the period, multiplied by
      183/365 (to reflect the one-half year period shown). Because the Fund is a
      feeder fund, the expense table example reflects the expenses of both the
      feeder fund and the master fund in which it invests.
**    Hypothetical 5% annual return before expenses is calculated by pro-rating
      the number of days in the most recent fiscal half-year divided by 365.

Notes to Financial Statements   CMA Money Fund

1. Significant Accounting Policies:

CMA Money Fund (the "Fund") is registered under the Investment Company Act of
1940, as amended, as a no-load, diversified, open-end management investment
company. The Fund seeks to achieve its investment objective by investing all of
its assets in the Master Money Trust (the "Trust"), which has the same
investment objective and strategies as the Fund. The value of the Fund's
investment in the Trust reflects the Fund's proportionate interest in the net
assets of the Trust. The performance of the Fund is directly affected by the
performance of the Trust. The financial statements of the Trust, including the
Schedule of Investments, are included elsewhere in this report and should be
read in conjunction with the Fund's financial statements. The Fund's financial
statements are prepared in conformity with U.S. generally accepted accounting
principles, which may require the use of management accruals and estimates.
Actual results may differ from these estimates. These unaudited financial
statements reflect all adjustments, which are, in the opinion of management,
necessary to present a fair statement of the results for the interim period. All
such adjustments are of a normal, recurring nature. The percentage of the Trust
owned by the Fund at September 30, 2005 was 48.9%. The following is a summary of
significant accounting policies followed by the Fund.

(a) Valuation of investments -- The Fund records its investment in the Trust at
fair value. Valuation of securities held by the Trust is discussed in Note 1(a)
of the Trust's Notes to Financial Statements, which are included elsewhere in
this report.

(b) Investment income and expenses -- The Fund records daily its proportionate
share of the Trust's income, expenses and realized and unrealized gains and
losses. In addition, the Fund accrues its own income and expenses.

(c) Income taxes -- 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.
Therefore, no federal income tax provision is required.

(d) Prepaid registration fees -- Prepaid registration fees are charged to
expense as the related shares are issued.

(e) Dividends and distributions to shareholders -- The Fund declares dividends
daily and reinvests daily such dividends (net of non-resident alien tax and
backup withholding tax withheld) in additional fund shares at net asset value.
Dividends and distributions are declared from the total of net investment income
and net realized gain or loss on investments.

(f) Investment transactions -- Investment transactions in the Trust are
accounted for on a trade date basis.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Administration Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), a wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."),
which is the limited partner. The Fund pays a monthly fee at an annual rate of
..25% of the Fund's average daily net assets for the performance of
administrative services (other than investment advice and related portfolio
activities) necessary for the operation of the Fund.

Pursuant to the Distribution and Shareholder Servicing Plan in compliance with
Rule 12(b)-1 under the Investment Company Act of 1940, Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("MLPF&S"), an affiliate of FAM, receives a
distribution fee from the Fund. The fee is accrued daily and paid monthly at the
annual rate of .125% of average daily net assets of the Fund for shareholders
whose Fund accounts are serviced by MLPF&S financial advisors, whether
maintained through MLPF&S or directly with each Fund's transfer agent. The
distribution fee is to compensate MLPF&S for providing, or arranging for the
provision of, account maintenance and sales and promotional activities and
services with respect to shares of the Fund.

Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co., is
the Fund's transfer agent. Interest is earned by the Fund from FDS based on the
difference, if any, between estimated and actual daily beneficial share
activity, which results in uninvested net proceeds from sales of Fund shares.

Certain officers and/or trustees of the Fund are officers and/or directors of
FAM, PSI, FDS, and/or ML & Co.

3. Transactions in Shares of Beneficial Interest:

The number of shares sold, reinvested and redeemed during the years corresponds
to the amounts included in the Statements of Changes in Net Assets for net
proceeds from sale of shares, value of shares reinvested and cost of shares
redeemed, respectively, since shares are recorded at $1.00 per share.

Notes to Financial Statements                                 Master Money Trust

1. Significant Accounting Policies:

Master Money Trust (the "Trust") is registered under the Investment Company Act
of 1940, as amended, and is organized as a Delaware statutory trust. The
Declaration of Trust permits the Trustees to issue nontransferable interest in
the Trust, subject to certain limitations. The Trust's financial statements are
prepared in conformity with U.S. generally accepted accounting principles, which
may require the use of management accruals and estimates. Actual results may
differ from these estimates. These unaudited financial statements reflect all
adjustments, which are, in the opinion of management, necessary to present a
fair statement of the results for the interim period. All such adjustments are
of a normal, recurring nature. The following is a summary of significant
accounting policies followed by the Trust.

(a) Valuation of investments -- Portfolio securities with remaining maturities
of greater than sixty days, for which market quotations are readily available,
are valued at market value. As securities transition from sixty-one to sixty
days to maturity, the difference between the valuation existing on the
sixty-first day before maturity and maturity value is amortized on a
straight-line basis to maturity. Securities maturing sixty days or less from
their date of acquisition are valued at amortized cost, which approximates
market value. For purposes of valuation, the maturity of a variable rate
security is deemed to be the next coupon date on which the interest rate is to
be adjusted. Other investments and assets for which market value quotations are
not available are valued at fair value as determined in good faith by or under
the direction of the Board of Trustees.

(b) Repurchase agreements -- The Trust may invest in U.S. government securities
pursuant to repurchase agreements. Under such agreements, the counterparty
agrees to repurchase the security at a mutually agreed upon time and price. The
Trust takes possession of the underlying securities, marks-to-market such
securities and, if necessary, receives additional securities daily to ensure
that the contract is fully collateralized. If the counterparty defaults and the
fair value of the collateral declines, liquidation of the collateral by the
Trust may be delayed or limited.

(c) Income taxes -- The Trust is classified as a partnership for federal income
tax purposes. As such, each investor in the Trust is treated as owner of its
proportionate share of the net assets, income, expenses and realized and
unrealized gains and losses of the Trust. Therefore, no federal income tax
provision is required. It is intended that the Trust's assets will be managed so
an investor in the Trust can satisfy the requirements of subchapter M of the
Internal Revenue Code.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Interest income (including amortization of premium and
discount) is recognized on the accrual basis.

(e) Securities lending -- The Trust may lend securities to financial
institutions that provide cash or securities issued or guaranteed by the U.S.
government as collateral, which will be maintained at all times in an amount
equal to at least 100% of the current market value of the loaned securities. The
market value of the loaned securities is determined at the close of business of
the Trust and any additional required collateral is delivered to the Trust on
the next business day. Where the Trust receives securities as collateral for the
loaned securities, it collects a fee from the borrower. The Trust typically
receives the income on the loaned securities but does not receive the income on
the collateral. Where the Trust receives cash collateral, it may invest such
collateral and retain the amount earned on such investment, net of any amount
rebated to the borrower. Loans of securities are terminable at any time and the
borrower, after notice, is required to return borrowed securities within five
business days. The Trust may pay reasonable finder's, lending agent,
administrative and custodial fees in connection with its loans. In the event
that the borrower defaults on its obligation to return borrowed securities
because of insolvency or for any other reason, the Trust could experience delays
and costs in gaining access to the collateral. The Trust also could suffer a
loss where the value of the collateral falls below the market value of the
borrowed securities, in the event of borrower default or in the event of losses
on investments made with cash collateral.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Trust has entered into an Investment Advisory Agree-ment with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML
& Co."), which is the limited partner.

FAM is responsible for the management of the Trust's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Trust. For such services, the Trust pays a monthly fee
based upon the average daily value of the Trust's net assets at the following
annual rates: .25% of the Trust's average daily net assets not exceeding $500
million; .175% of the average daily net assets in excess of $500 million, but
not exceeding $1 billion; and .125% of the average daily net assets in excess of
$1 billion.

The Trust has received an exemptive order from the Securities and Exchange

Activities and Composition of the Board of Trustees

All but one member of the Board of Trustees is an independent trustee whose only
affiliation with Fund Asset Management, L.P. (the "Investment Adviser") or other
Merrill Lynch affiliates is as a trustee of the Master Money Trust (the "Trust")
and the Fund and certain other funds advised by the Investment Adviser or its
affiliates. The Chairman of the Board is also an independent trustee. New
trustee nominees are chosen as nominees by a Nominating Committee comprised of
independent Trustees. All independent Trustees also are members of the Board's
Audit Committee and the independent Trustees meet in executive session at each
in-person Board meeting. The Board and Audit Committee meet in person for at
least two days each quarter and conduct other in-person and telephone meetings
throughout the year, some of which are formal board meetings, and some of which
are informational meetings. The independent counsel to the independent Trustees
attends all in-person Board and Audit Committee meetings and other meetings at
the independent Trustees' request.

Investment Advisory Agreement -- Matters Considered by the Board

Every year, the Board considers approval of the investment advisory agreement
between the Investment Adviser and the Trust (the "Investment Advisory
Agreement"). The Board also reviews and evaluates the performance of and
services provided by the Investment Adviser throughout each year. The Board
assesses the nature, scope and quality of the services provided to the Trust and
the Fund by the personnel of the Investment Adviser and its affiliates,
including administrative services, shareholder services, oversight of fund
accounting, marketing services and assistance in meeting legal and regulatory
requirements. The Board also receives and assesses information regarding the
services provided to the Trust and the Fund by certain unaffiliated service
providers.

At various times throughout the year, the Board also considers a range of
information in connection with its oversight of the services provided by the
Investment Adviser and its affiliates. Among the matters considered are: (a) any
fees (in addition to management fees) paid to the Investment Adviser and its
affiliates by the Trust or by the Fund, such as transfer agency fees and fees
for marketing and distribution; (b) Trust/Fund operating expenses paid to third
parties; (c) the resources devoted to and compliance reports relating to the
Trust's and the Fund's investment objective, policies and restrictions, and its
compliance with its Code of Ethics and the Investment Adviser's compliance
policies and procedures; and (d) the nature, cost and character of
non-investment management services provided by the Investment Adviser and its
affiliates.

The Board believes that the Investment Adviser is one of the most experienced
global asset management firms and considers the overall services provided by the
Investment Adviser to be generally of high quality. The Board also believes that
the Investment Adviser is financially sound and well managed and notes that the
Investment Adviser is affiliated with one of America's largest financial firms.
The Board works closely with the Investment Adviser in overseeing the Investment
Adviser's efforts to achieve good performance. As part of this effort, the Board
discusses portfolio Investment Adviser effectiveness and, when performance is
not satisfactory, discusses with the Investment Adviser taking steps such as
changing investment personnel.

Annual Consideration of Approval by the Board of Trustees

In the period prior to the Board meeting to consider renewal of the Investment
Advisory Agreement, the Board requests and receives materials specifically
relating to the Trust's Investment Advisory Agreement. These materials include
(a) information compiled by Lipper Inc. ("Lipper") on the fees and expenses and
the investment performance of the Trust/Fund or its predecessor (which had the
same investment objective and strategies as the Trust) as compared to a
comparable group of funds as classified by Lipper; (b) a discussion by the
Trust's/Fund's portfolio management team on investment strategies used by the
Trust/Fund during its most recent fiscal year; (c) information on the
profitability to the Investment Adviser and its affiliates of the Investment
Advisory Agreement and other relationships with the Trust and/or Fund; (d)
information on the profitability to the Investment Adviser and its affiliates of
the Investment Advisory Agreements and other relationships with the Trust/Fund;
and (e) information provided by the Investment Adviser concerning investment
advisory fees charged to other clients, such as institutional clients. The Board
also considers other matters it deems important to the approval process such as
payments made to the Investment Adviser or its affiliates relating to the
distribution of Fund shares, services related to the valuation and pricing of
Trust/Fund portfolio holdings, allocation of Trust/Fund brokerage fees, and
direct and indirect benefits to the Investment Adviser and its affiliates from
their relationship with the Trust/Fund.

Certain Specific Renewal Data

In connection with the most recent renewal of the Trust's Investment Advisory
Agreement in August 2005, the independent Trustees' and Board's review included
the following:

Investment Adviser's Services and Fund Performance -- The Board reviewed the
nature, extent and quality of services provided by the Investment Adviser,
including the investment advisory services and the resulting performance of the
Fund. The Board focused primarily on the Investment Adviser's investment
advisory services and the Fund's investment performance, having concluded that
the other services provided to the Trust/Fund by the Investment Adviser were
satisfactory. The Board compared Fund performance -- both including and
excluding the effects of the Trust's/Fund's fees and expenses -- to the
performance of a comparable group of mutual funds, and the performance of a
relevant index or combination of indexes. While the Board reviews performance
data quarterly, consistent with the Investment Adviser's investment goals, the
Board attaches primary importance to performance over relatively long periods of
time, typically three to five years. The Board noted that the performance of the
Trust/Fund or its predecessor (which had the same objective and strategies of
the corresponding Trust) was in the second quintile of its Lipper performance
group for the one-, three- and five-year periods ended May 31, 2005. The Board
concluded that the Trust's/Fund's performance was consistent with the
continuation of the management fee rate at its current level and the renewal of
the applicable Investment Advisory Agreement.

The Investment Adviser's Personnel and Investment Process -- The Board reviewed
the Trust's/Fund's investment objectives and strategies. The Board discussed
with senior management of the Investment Adviser responsible for investment
operations and the senior management of the Investment Adviser's taxable
fixed-income investing group the strategies being used to achieve the stated
objectives. Among other things, the Board considered the size, education and
experience of the Investment Adviser's investment staff, its use of technology,
and the Investment Adviser's approach to training and retaining portfolio
Investment Advisers and other research, advisory and management personnel. The
Board also reviewed the Investment Adviser's compensation policies and practices
with respect to the Trust's/Fund's portfolio manager. The Board also considered
the experience of the Trust's portfolio manager and noted that Mr. Mejzak has
over ten years' experience investing in money market securities. The Board
concluded that the Investment Adviser and its investment staff and the
Trust's/Fund's portfolio manager have extensive experience in analyzing and
managing the types of investments used by the Trust and the Fund and that the
Trust and the Fund benefit from that expertise.

Management Fees and Other Expenses -- The Board reviewed the Trust's/Fund's
contractual management fee rate and actual management fee rate as a percentage
of total assets at common asset levels -- the actual rate includes advisory and
administrative service fees and the effects of any fee waivers -- compared to
the other funds in its Lipper category. It also compares the Trust's/Fund's
total expenses to those of other comparable funds. The Board considered the
services provided to and the fees charged by the Investment Adviser to other
types of clients such as institutional clients. The Board noted that, as a
general matter, fees charged to institutional clients were lower than the fees
charged to the Trust/Fund, but determined that the Investment Adviser provided
less extensive services to such clients, which tended to hold much larger
accounts. The Board noted that the contractual management fee was equal to the
median, and the actual management fee was slightly above the median fee the
comparable funds in the Lipper group. The Board concluded that the management
fee and fee rate and overall expense ratio were reasonable when compared to
those of other comparable funds.

Profitability -- The Board considered the cost of the services provided to the
Trust and Fund by the Investment Adviser and the Investment Adviser's and its
affiliates' profits in relating to the management and distribution of the Trust
and Fund and the MLIM/FAM-advised funds. As part of its analysis, the Board
reviews the Investment Adviser's and its affiliates' methodology in allocating
costs to the management of the Trust/Fund and concluded that there was a
reasonable basis for the allocation. The Board believes the profits of the
Investment Adviser and its affiliates are acceptable in relation to the nature
and quality of services provided and given the level of fees and expenses
overall. The Board also considered the federal court decisions discussing an
investment adviser's

Disclosure of Investment Advisory Agreement (concluded)

profitability, and the profitability levels considered to be reasonable in those
decisions.

Economies of Scale -- The Board considered the extent to which economies of
scale might be realized as the assets of the Trust/Fund increase and whether
there should be changes in the management fee rate or structure in order to
enable a Trust and a Fund to participate in these economies of scale. The Board
noted that the Trust's/Fund's current management fee rate schedule includes
breakpoints that would reduce the Trust's/Fund's management fee rate if its
assets increase above certain levels. The Board determined that no changes were
currently necessary.

Conclusion

After the independent Trustees deliberated in executive session, the Board,
including all of the independent Trustees, approved the renewal of the existing
Investment Advisory Agreement, concluding that the advisory fee was reasonable
in relation to the services provided and that a contract renewal was in the best
interests of the shareholders.
