MAS OVERVIEW
- ---------------------------------------------------------
The Value Portfolio combines Miller Anderson & Sherrerd's disciplined valuation
process with the judgment gained through considerable experience in low P/E
investing, emphasizing large capitalization stocks from all market sectors. MAS
considers a company's intrinsic worth, projected earnings and other measures to
help determine if its current price makes it a strong candidate for value
investing. MAS also employs a formal sell discipline. Individual positions are
sold when price appreciation or earnings-per-share deterioration raises the
current P/E ratio.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
# Represents an investment in the Institutional Class.
 
< Represents an investment in the Investment Class which commenced operations
4/10/96. Total returns for periods beginning prior to this date are based on the
performance of the Institutional Class and do not include the 0.15% Shareholder
Servicing Fee applicable to the Investment Class.
 
@ Represents an investment in the Adviser Class which commenced operations
1/16/98. Total returns for periods beginning prior to this date are based on the
performance of the Institutional Class and do not include the 0.25% 12b-1 Fee
applicable to the Adviser Class. It is expected that, over time, returns for the
Adviser Class will be lower than for the other classes due to the higher
expenses charged.
 
Total returns for the Investment Class of the Portfolio reflect expenses
reimbursed by the Adviser for certain periods. Without such reimbursements,
total returns would have been lower.
 
* Total returns are compared to the S&P 500 Index, an unmanaged market index.
Returns for periods less than one year are cumulative.

The Small Cap Value Portfolio applies Miller Anderson & Sherrerd's value
investing to small-and medium-sized companies, combining MAS's disciplined
valuation process with the judgment gained through considerable experience in
low P/E investing. The Portfolio keeps sector weights within 5% of the sector
weights of the Russell 2000 Index, with strategic over- and under-weightings
assigned to different economic sectors and industries. This portfolio is not
currently open to new investors.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results. Small-capitalization stock prices have
experienced a greater degree of market volatility than those of
large-capitalization companies.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
* Total returns are compared to the Russell 2000 Index, an unmanaged market
index. Returns for periods less than one year are cumulative.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results. Foreign investments are subject to certain
risks such as currency fluctuations, economic instability, and political
developments.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.

MID CAP GROWTH
PORTFOLIO (UNAUDITED)
 
MAS OVERVIEW
- ---------------------------------------------------------
The Mid Cap Growth Portfolio invests in the common stock of small- and
medium-sized companies with superior long-term earnings-growth potential and
rising earnings estimates. MAS's four-part process combines quantitative,
fundamental, and valuation analysis with a strict sell discipline. A
quantitative screen sorts the stocks in each sector based on estimate revision.
MAS then conducts fundamental research on purchase candidates, seeking strong
sales growth, rising profit margins, and high returns on capital. Qualitative
measures, including management quality and strategic positioning, are also
reviewed. This fundamental analysis is coupled with valuation analysis to weed
out the most overvalued securities. Holdings are sold when
earnings-estimate-revisions deteriorate, when our fundamental research uncovers
unfavorable trends, or when their valuations exceed the level that we believe is
reasonable given their growth prospects.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results. Small-capitalization stock prices have
experienced a greater degree of market volatility than those of
large-capitalization companies.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.

MAS OVERVIEW
- ---------------------------------------------------------
The Mid Cap Value Portfolio applies Miller Anderson & Sherrerd's value investing
to medium-sized companies, combining MAS's disciplined valuation process with
the judgment gained through considerable experience in low P/E investing. The
Portfolio keeps sector weights within 5% of the sector weights of the S&P
Mid-Cap 400 Index, with strategic over- and under-weightings assigned to
different economic sectors and industries.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results. Small-capitalization stock prices have
experienced a greater degree of market volatility than those of
large-capitalization companies.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
# Represents an investment in the Institutional Class.
 
< Represents an investment in the Investment Class which commenced operations
5/10/96. Total returns for periods beginning prior to this date are based on the
performance of the Institutional Class and do not include the 0.15% Shareholder
Servicing Fee applicable to the Investment Class.
 
Total returns for the Portfolio reflect expenses waived and/or reimbursed by the
Adviser for certain periods. Without such waivers and/or reimbursements, total
returns would have been lower.
 
* The Mid Cap Value Portfolio commenced operations on 12/30/94. Total returns
are compared to the S&P MidCap 400 Index, an unmanaged market index. Returns for
periods less than one year are cumulative.

EMERGING MARKETS VALUE
PORTFOLIO (UNAUDITED)
 
MAS OVERVIEW
- ---------------------------------------------------------
The Emerging Markets Value Portfolio invests primarily in common stocks of
emerging markets issuers throughout the world, investing in more than 50 stocks
from more than 20 countries. Miller Anderson & Sherrerd evaluates both short-
term and long-term international economic trends and relative attractiveness of
emerging markets and individual emerging market securities to achieve the
Portfolio's objective of long-term capital growth. Valuation techniques and
business dynamics are emphasized in determining country allocation and stock
selection. Foreign currency exposure is actively managed, but is not often
hedged due to the high cost of hedging transactions.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results. Foreign investments are subject to certain
risks such as currency fluctuations, economic instability, and political
developments.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
Total returns for the Portfolio reflect expenses waived and/or reimbursed by the
Adviser for certain periods. Without such waivers and/or reimbursements, total
returns would have been lower.
 
* The Emerging Markets Value Portfolio commenced operations on 2/28/95. Total
returns are compared to the Morgan Stanley Capital International Emerging
Markets Free Index, an unmanaged market index. Returns for periods less than one
year are cumulative.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
# Represents an investment in the Institutional Class.
 
< Represents an investment in the Investment Class which commenced operations
  10/15/96. Total returns for periods beginning prior to this date are based on
  the performance of the Institutional Class and do not include the 0.15%
  Shareholder Servicing Fee applicable to the Investment Class.

@ Represents an investment in the Adviser Class which commenced operations
  11/7/96. Total returns for periods beginning prior to this date are based on
  the performance of the Institutional Class and do not include the 0.25%
  12b-1 Fee applicable to the Adviser Class.
 
  Total returns for the Investment and Adviser Classes of the Portfolio
  reflect expenses reimbursed by the Adviser for certain periods. Without such
  reimbursements, total returns would have been lower.
 
* Total returns are compared to the Salomon Broad Investment Grade Index, an
  unmanaged market index. Returns for periods less than one year are
  cumulative.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
Total returns for the Portfolio reflect expenses waived and/or reimbursed by the
Adviser for certain periods. Without such waivers and/or reimbursements, total
returns would have been lower.
 
* The Domestic Fixed Income Portfolio (formerly known as the Select Fixed Income
Portfolio) commenced operations on 9/30/87. Pursuant to a vote of the
Portfolio's shareholders on December 19, 1994, the Portfolio's investment
policies were changed to emphasize fixed-income securities of domestic issuers
rated A or higher. Shareholders then voted on May 1, 1997, to permit the
Portfolio to invest a limited portion of its assets in fixed-income securities
of domestic issuers rated BBB at the time of purchase. The Portfolio's
performance pattern may have been affected by these changes. Total returns are
compared to the Salomon Broad Investment Grade Index, an unmanaged market index.
Returns for periods less than one year are cumulative.

PORTFOLIO (UNAUDITED)
 
MAS OVERVIEW
- ---------------------------------------------------------
The High Yield Portfolio applies Miller Anderson & Sherrerd's analytical
capabilities to a specialized fixed-income fund, investing primarily in below-
investment-grade corporate bonds selected through study of the credit-worthiness
of the underlying companies. MAS's strategy uses equity and fixed-income
valuation techniques and analyses of economic and industry trends to determine
the Portfolio's structure. Individual securities are selected and monitored by
managers specializing in corporate bonds and using in-depth financial analysis
to uncover opportunities in undervalued issues.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results. High-yield fixed-income securities,
otherwise known as "junk bonds," represent a much greater risk of default and
tend to be more volatile than higher-rated bonds.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
# Represents an investment in the Institutional Class.
 
< Represents an investment in the Investment Class which commenced operations
  5/21/96. Total returns for periods beginning prior to this date are based on
  the performance of the Institutional Class and do not include the 0.15%
  Shareholder Servicing Fee applicable to the Investment Class.
 
@ Represents an investment in the Adviser Class which commenced operations
  1/31/97. Total returns for periods beginning prior to this date are based on
  the performance of the Institutional Class and do not include the 0.25% 12b-1
  Fee applicable to the Adviser Class. It is expected that, over time, returns
  for the Adviser Class will be lower than for the other classes due to the
  higher expenses charged.
 
  Total returns for the Institutional and Investment Classes of the Portfolio
  reflect expenses reimbursed by the Adviser for certain periods. Without such
  reimbursements, total returns would have been lower.
 
* The High Yield Portfolio commenced operations on 2/28/89. Total returns are
  compared to the Salomon High Yield Index, an unmanaged market index. Returns
  for periods less than one year are cumulative. STATEMENT OF NET ASSETS FIXED

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
* The Fixed Income Portfolio II commenced operations on 8/31/90. Pursuant to a
vote of the Portfolio's shareholders on May 12, 1997, the Portfolio's investment
policies were changed to allow the Portfolio to invest in fixed-income
securities of domestic issuers rated BBB or higher at the time of purchase. The
Portfolio's performance pattern may have been affected by this change. Total
returns are compared to the Salomon Broad Investment Grade Index, an unmanaged
market index. Returns for periods less than one year are cumulative.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
Total returns for the Portfolio reflect expenses waived and/or reimbursed by the
Adviser for certain periods. Without such waivers and/or reimbursements, total
returns would have been lower.
 
* The Mortgage-Backed Securities Portfolio commenced operations on 1/31/92.
Total returns are compared to the Lehman Brothers Mortgage Index, an unmanaged
market index. Returns for periods less than one year are cumulative.

LIMITED DURATION
PORTFOLIO (UNAUDITED)
 
MAS OVERVIEW
- ---------------------------------------------------------
The Limited Duration Portfolio has a dual philosophy for achieving its
objective: earn positive real returns and minimize the possibility of a negative
return in a single quarter. Limiting average duration to between one and three
years helps control interest rate risk while allowing for a broad spectrum of
investment opportunities. The Portfolio invests in U.S. Treasury and agency
securities, investment-grade corporate bonds, mortgage-backed securities and
money market instruments, including floating-rate notes.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
Total returns for the Portfolio reflect expenses waived and/or reimbursed by the
Adviser for certain periods. Without such waivers and/or reimbursements, total
returns would have been lower.
 
* The Limited Duration Portfolio commenced operations on 3/31/92. Total returns
are compared to the Salomon 1-3 Year Treasury/Government Sponsored Index, an
unmanaged market index. Returns for periods less than one year are cumulative.

MUNICIPAL
PORTFOLIO (UNAUDITED)
 
MAS OVERVIEW
- ---------------------------------------------------------
The Municipal Portfolio invests in debt obligations issued by state and local
governments or their agencies and in other fixed-income securities. Portfolio
structure reflects three key elements: duration, sector selection and security
selection. Duration varies depending on Miller Anderson & Sherrerd's outlook for
changes in interest rates, becoming longer than the benchmark index in periods
when MAS expects rates to fall and shorter in periods when MAS expects them to
rise. Investments in individual securities and sectors reflect MAS's views on
the risks and rewards available in the various bonds offered in the market.
Normally, at least 80% of the Portfolio will be invested in municipal
securities. Taxable securities are included only in cases where MAS believes
they will improve the fund's risk/reward profile on an after-tax basis.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
Total returns for the Portfolio reflect expenses waived and/or reimbursed by the
Adviser for certain periods. Without such waivers and/or reimbursements, total
returns would have been lower.
 
The Portfolio was initially focused on long-term securities. On April 15, 1996,
the Portfolio's investment policies were changed by shareholder vote to
emphasize fixed-income securities of shorter duration. The Portfolio's
performance pattern may have been affected by this change.
 
* The Municipal Portfolio commenced operations on 10/1/92. Total returns are
compared to the Lehman 5 Year Municipal Index and the Lehman 10 Year Municipal
Index, both unmanaged market indices. Returns for periods less than one year are
cumulative.

PA MUNICIPAL
PORTFOLIO (UNAUDITED)
 
MAS OVERVIEW
- ---------------------------------------------------------
The PA Municipal Portfolio invests in municipal debt securities exempt from
Pennsylvania income tax, and in other fixed-income securities. Portfolio
structure reflects three key elements: duration, sector selection and security
selection. Duration varies depending on Miller Anderson & Sherrerd's outlook for
changes in interest rates, becoming longer than the benchmark index in periods
when MAS expects rates to fall and shorter in periods when MAS expects them to
rise. Investments in individual securities and sectors reflect MAS's views on
the risks and rewards available in the various bonds offered in the market.
Normally, at least 80% of the Portfolio will be invested in municipal
securities, with at least 65% invested in Pennsylvania municipal securities.
Taxable securities are included only in cases where MAS believes they will
improve the fund's risk/reward profile on an after-tax basis.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
Total returns for the Portfolio reflect expenses waived and/or reimbursed by the
Adviser for certain periods. Without such waivers and/or reimbursements, total
returns would have been lower.
 
The Portfolio was initially focused on long-term securities. On April 15, 1996,
the Portfolio's investment policies were changed by shareholder vote to
emphasize fixed-income securities of shorter duration. The Portfolio's
performance pattern may have been affected by this change.
 
* The PA Municipal Portfolio commenced operations on 10/1/92. Total returns are
compared to the Lehman 5 Year Municipal Index and the Lehman 10 Year Municipal
Index, both unmanaged market indices. Returns for periods less than one year are
cumulative.

GLOBAL FIXED INCOME
PORTFOLIO (UNAUDITED)
 
MAS OVERVIEW
- ---------------------------------------------------------
The Global Fixed Income Portfolio invests in high-grade fixed-income securities
around the world, including the United States. Miller Anderson & Sherrerd
manages the duration, country, and currency exposure of the portfolio by
combining research on relative values with analyses of economic, interest rate,
and exchange rate trends. Particular attention is paid to prospective inflation
and real interest rates. The Portfolio will tend to invest in those countries
offering the highest real interest rates and steepest yield curves, after
adjusting for differences in the fiscal soundness of each country. Foreign
currency exposure is handled as a separate management decision and foreign
currencies which MAS judges to be significantly overvalued are hedged.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results. Foreign investments are subject to certain
risks such as currency fluctuations, economic instability, and political
developments.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
Total returns for the Portfolio reflect expenses waived and/or reimbursed by the
Adviser for certain periods. Without such waivers and/or reimbursements, total
returns would have been lower.
 
* The Global Fixed Income Portfolio commenced operations on 4/30/93. Total
returns are compared to the Salomon World Government Bond Index, an unmanaged
market index. Returns for periods less than one year are cumulative.

INTERNATIONAL FIXED
INCOME PORTFOLIO (UNAUDITED)
 
MAS OVERVIEW
- ---------------------------------------------------------
The International Fixed Income Portfolio invests in high-grade foreign
fixed-income securities. Miller Anderson & Sherrerd manages the duration,
country, and currency exposure of the Portfolio by combining research on
relative values with analyses of economic, interest rate, and exchange rate
trends. Particular attention is paid to prospective inflation and real interest
rates. The Portfolio will tend to invest in those countries offering the highest
real interest rates and steepest yield curves, after adjusting for differences
in the fiscal soundness of each country. Foreign currency exposure is handled as
a separate management decision and foreign currencies which MAS judges to be
significantly overvalued are hedged.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results. Foreign investments are subject to certain
risks such as currency fluctuations, economic instability, and political
developments.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
Total returns for the Portfolio reflect expenses waived and/or reimbursed by the
Adviser for certain periods. Without such waivers and/or reimbursements, total
returns would have been lower.
 
* The International Fixed Income Portfolio commenced operations on 4/29/94.
Total returns are compared to the Salomon World Government Bond Ex-U.S. Index,
an unmanaged market index. Returns for periods less than one year are
cumulative.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
Total returns for the Portfolio reflect expenses waived and/or reimbursed by the
Adviser for certain periods. Without such waivers and/or reimbursements, total
returns would have been lower.
 
* The Intermediate Duration Portfolio commenced operations on 10/3/94. Total
returns are compared to the Lehman Brothers Intermediate Government/Corporate
Bond Index, an unmanaged market index. Returns for periods less than one year
are cumulative.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results. Foreign investments are subject to certain
risks such as currency fluctuations, economic instability, and political
developments. High-yield fixed income securities, otherwise known as "junk
bonds," represent a much greater risk of default and tend to be more volatile
than higher-rated bonds.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
Total returns for the Portfolio reflect expenses waived and/or reimbursed by the
Adviser for certain periods. Without such waivers and/or reimbursements, total
returns would have been lower.
 
* The Multi-Market Fixed Income Portfolio commenced operations on 10/1/97. Total
returns are compared to the Salomon Broad Investment Grade Index and the Salomon
World Government Bond Ex-U.S. Index, both unmanaged market indices. Returns for
periods less than one year are cumulative.

The Balanced Portfolio provides ongoing asset allocation management with Miller
Anderson & Sherrerd's core equity and fixed-income management strategies. The
Portfolio considers a 60% equity/40% fixed-income mix as a neutral, or
starting-point investment. As expected future returns increase in one asset
class versus the other, the mix between asset classes will change.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
# Represents an investment in the Institutional Class.
 
< Represents an investment in the Investment Class which commenced operations
4/4/97. Total returns for periods beginning prior to this date are based on the
performance of the Institutional Class and do not include the 0.15% Shareholder
Servicing Fee applicable to the Investment Class.
 
@ Represents an investment in the Adviser Class which commenced operations
11/1/96. Total returns for periods beginning prior to this date are based on the
performance of the Institutional Class and do not include the 0.25% 12b-1 Fee
applicable to the Adviser Class. It is expected that, over time, returns for the
Adviser Class will be lower than for the other classes due to the higher
expenses charged.
 
Total returns for the Adviser Class of the Portfolio reflect expenses reimbursed
by the Adviser for certain periods. Without such reimbursements, total returns
would have been lower.
 
* The Balanced Portfolio commenced operations on 12/31/92. Total returns are
compared to the S&P 500 Index and the Salomon Broad Investment Grade Index, both
unmanaged market indices. Returns for periods less than one year are cumulative.

MULTI-ASSET-CLASS
PORTFOLIO (UNAUDITED)
 
MAS OVERVIEW
- ---------------------------------------------------------
The Multi-Asset-Class Portfolio provides global asset allocation management with
a level of international diversification that is appropriate for U.S.-oriented
investors. Miller Anderson & Sherrerd manages investments in five asset classes,
and considers a benchmark consisting of 50% U.S. equities, 14% foreign equities,
24% U.S. fixed-income, 6% foreign fixed-income and 6% high yield to be a
neutral, or starting-point investment. Allocations are based on a value-driven
approach which favors those equity markets offering the highest risk-adjusted
expected returns and those bond markets offering the highest real interest rates
and steepest yield curves.

Total returns are net of all fees. Total returns represent past performance and
are not indicative of future results. Foreign investments are subject to certain
risks such as currency fluctuations, economic instability, and political
developments. High-yield fixed-income securities, otherwise known as "junk
bonds," represent a much greater risk of default and tend to be more volatile
than higher-rated bonds.
 
The investment return and principal value of an investment will fluctuate so
that an investor's shares, when redeemed, may be worth either more or less than
their original cost.
 
# Represents an investment in the Institutional Class.
 
< Represents an investment in the Investment Class which commenced operations
  6/10/96. Total returns for periods beginning prior to this date are based on
  the performance of the Institutional Class and do not include the 0.15%
  Shareholder Servicing Fee applicable to the Investment Class.
 
Total returns for the Portfolio reflect expenses waived and/or reimbursed by the
Adviser for certain periods. Without such waivers and/or reimbursements, total
returns would have been lower.
 
* The Multi-Asset-Class Portfolio commenced operations on 7/29/94. Total returns
  are compared to the S&P 500 Index, the Salomon Broad Investment Grade Index
  and the Morgan Stanley Capital International EAFE-GDP Weighted Index, all
  unmanaged market indices. Returns for periods less than one year are
  cumulative.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
- --------------------------------------------------------------------------------
 
MAS Funds (the "Fund") is registered under the Investment Company Act of 1940
as an open-end investment company. At March 31, 1998, the Fund was comprised of
twenty-five active portfolios (each referred to as a "Portfolio"). The
Multi-Market Fixed Income Portfolio commenced operations on October 1, 1997.
The Funds may offer up to three different classes of shares for certain
Portfolios -- Institutional Class shares, Investment Class shares and Adviser
Class shares.
 
The Equity Portfolio began offering Adviser Class shares on January 16, 1998.
Each class of shares has identical voting rights (except shareholders of a
Class have exclusive voting rights regarding any matter relating solely to that
Class of shares), dividend, liquidation and other rights, except each class
bears different distribution fees as described in Note D. The financial
statements for the Advisory Foreign Fixed Income and Advisory Mortgage
Portfolios are presented separately.
 
A. SIGNIFICANT ACCOUNTING POLICIES. The following significant accounting
policies are in conformity with generally accepted accounting principles for
investment companies. Such policies are consistently followed by the Fund in
the preparation of its financial statements. Generally accepted accounting
principles may require management to make estimates and assumptions that affect
the reported amounts and disclosures in the financial statements. Actual
results may differ from those estimates.
 
1.  SECURITY VALUATION: Market values for equity securities listed on the New
    York Stock Exchange ("NYSE") or other U.S. exchanges or NASDAQ are based on
    the latest quoted sales prices as of the close of the NYSE (normally 4:00
    p.m. Eastern Time) on the valuation date; securities not traded on the
    valuation date are valued at the mean of the most recent quoted bid and
    asked prices. Equity securities not listed are valued at the mean of the
    most recent bid and asked prices. Securities listed on foreign exchanges
    are valued at the latest quoted sales prices. Bonds, including municipal
    bonds, and other fixed income securities are valued using brokers'
    quotations or on the basis of prices, provided by a pricing service, which
    are based primarily on institutional size trading in similar groups of
    securities. Mortgage-backed securities issued by certain government-related
    organizations are valued using brokers' quotations which are based on a
    matrix system which considers such factors as other security prices, yields
    and maturities. Securities in the Cash Reserves Portfolio, and other
    Portfolios' short term securities, are valued using the amortized cost
    method of valuation, which in the opinion of the Board of Trustees reflects
    fair value. Securities for which no quotations are readily available
    (including restricted securities) are valued at their fair value as
    determined in good faith using methods approved by the Board of Trustees.
 
2.  FEDERAL INCOME TAXES: It is each Portfolio's intention to continue to
    qualify as a regulated investment company and distribute all of its taxable
    and tax-exempt income. Accordingly, no provision for Federal income taxes
    is required in the financial statements.
 
3.  REPURCHASE AGREEMENTS: Securities pledged as collateral for repurchase
    agreements are held by the Portfolios' custodian bank until maturity of the
    repurchase agreements. Provisions of the agreements ensure that the market
    value of the collateral is at least equal to the repurchase value in the
    event of a default; however, in the event of default or bankruptcy by the
    other party to the agreement, realization and/or retention of the
    collateral may be subject to legal proceedings.
 
    Pursuant to an Exemptive Order issued by the Securities and Exchange
    Commission, the Portfolios may transfer their uninvested cash balances into
    a joint trading account with other Portfolios of the Fund which invests in
    one or more repurchase agreement. This joint repurchase agreement is
    covered by the same collateral requirements as discussed above.

- --------------------------------------------------------------------------------
 
4.  FUTURES: Futures contracts (secured by cash and securities deposited with
    brokers as "initial margin") are valued based upon their quoted daily
    settlement prices; changes in initial settlement value (represented by cash
    paid to or received from brokers as "variation margin") are accounted for
    as unrealized appreciation (depreciation). When futures contracts are
    closed, the difference between the opening value at the date of purchase
    and the value at closing is recorded as realized gains or losses in the
    Statement of Operations.
 
    Futures contracts may be used by each Portfolio, except the Cash Reserves
    Portfolio, in order to hedge against unfavorable changes in the value of
    securities or to attempt to realize profits from the value of the
    underlying securities.
 
    Futures contracts involve market risk in excess of the amounts recognized
    in the Statement of Net Assets. Risks arise from the possible movements in
    security values underlying these instruments. The change in value of
    futures contracts primarily corresponds with the value of their underlying
    instruments, which may not correlate with the change in value of the hedged
    investments. In addition, there is the risk that a Portfolio may not be
    able to enter into a closing transaction because of an illiquid secondary
    market.
 
5.  SWAP AGREEMENTS: Each Portfolio, except the Cash Reserves and Mid Cap
    Growth Portfolios, may enter into swap agreements to exchange the return
    generated by one instrument for the return generated by another instrument.
    The following summarizes swaps entered into by the Portfolios:
 
    Interest Rate Swaps: Interest rate swaps involve the exchange of
    commitments to pay and receive interest based on a notional principal
    amount. Net periodic interest payments to be received or paid are accrued
    daily and are recorded in the Statement of Operations as an adjustment to
    interest income. Interest rate swaps are marked-to-market daily based upon
    quotations from market makers and the change, if any, is recorded as
    unrealized appreciation or depreciation in the Statement of Operations.
 
    Total Return Swaps: Total return swaps involve commitments to pay interest
    in exchange for a market-linked return based on a notional amount. To the
    extent the total return of the security or index underlying the transaction
    exceeds or falls short of the offsetting interest rate obligation, the
    Portfolio will receive a payment from or make a payment to the
    counterparty, respectively. Total return swaps are marked-to-market daily
    based upon quotations from market makers and the change, if any, is
    recorded as unrealized gains or losses in the Statement of Operations.
    Periodic payments received or made at the end of each measurement period,
    but prior to termination, are recorded as realized gains or losses in the
    Statement of Operations.
 
    Realized gains or losses on maturity or termination of interest rate and
    total return swaps are presented in the Statement of Operations. Because
    there is no organized market for these swap agreements, the value reported
    in the Statement of Net Assets may differ from that which would be realized
    in the event the Portfolio terminated its position in the agreement. Risks
    may arise upon entering into these agreements from the potential inability
    of the counterparties to meet the terms of the agreements and are generally
    limited to the amount of net interest payments to be received, if any, at
    the date of the default.
 
6.  INTEREST RATE FLOOR AND CAP AGREEMENTS: Each Portfolio, except the Cash
    Reserves Portfolio, may hold or write interest rate floors or caps to
    protect itself against fluctuation in interest rates. When a Portfolio
    writes an interest rate floor, it agrees to make periodic interest payments
    to the holder of the interest rate floor based on a notional principal
    amount to the extent that

                                       169
<PAGE>   172
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
 
    a specified interest index falls below a specified interest rate. When a
    Portfolio writes an interest rate cap, it agrees to make periodic interest
    payments to the holder of the interest rate cap based on a notional
    principal amount to the extent that a specified interest index rises above
    a specified interest rate. Any premium received by a Portfolio is recorded
    as a liability and is amortized to interest income over the term of the
    agreement. Any premium paid by a Portfolio is recorded as an asset and is
    accreted against interest income over the term of the agreement. Interest
    rate caps and floors are marked-to-market daily based on quotations from
    market makers and the change, if any, is recorded as unrealized
    appreciation or depreciation in the Statement of Operations. Periodic
    receipts or payments of interest, if any, are recorded in the interest
    income account on the Statement of Operations. Realized gains or losses
    from these agreements are disclosed in the Statement of Operations.
 
    Because there is no organized market for these agreements, the value
    reported in the Statement of Net Assets may differ from that which would be
    realized in the event the Portfolio terminated its position in the
    agreement. Entering into these agreements involves, to varying degrees,
    elements of interest rate and market risk in excess of the amount
    recognized in the Statement of Net Assets. Such risks involve the
    possibility that there may be no liquid market for these agreements and
    that there may be adverse changes in the interest rates or the index
    underlying these transactions. Risk may arise upon entering into these
    agreements from the potential inability of the counterparties to meet the
    terms of the agreements and are generally limited to the amount of net
    interest payments to be received.
 
7.  STRUCTURED INVESTMENTS: Certain Portfolios may invest in structured
    investments whose values are linked either directly or inversely to changes
    in foreign currencies, interest rates, commodities, indices, or other
    underlying instruments. A Portfolio uses these securities to increase or
    decrease its exposure to different underlying instruments and to gain
    exposure to markets that might be difficult to invest in through
    conventional securities. Structured investments may be more volatile than
    their underlying instruments, but any loss is limited to the amount of the
    original investment.
 
8.  DELAYED DELIVERY COMMITMENTS: Each Portfolio, except the Cash Reserves
    Portfolio, may purchase or sell securities on a when-issued or forward
    commitment basis. Payment and delivery may take place a month or more after
    the date of the transaction. The price of the underlying securities and the
    date when the securities will be delivered and paid for are fixed at the
    time the transaction is negotiated. Collateral consisting of liquid
    securities or cash is maintained in an amount at least equal to these
    commitments.
 
9.  PURCHASED OPTIONS: Certain Portfolios may purchase call and put options on
    their portfolio securities. A call option, upon payment of a premium, gives
    the purchaser of the option the right to buy, and the seller the obligation
    to sell, the underlying instrument at the exercise price. The purchase of a
    call option might be intended to protect the Portfolio against an increase
    in the price of the underlying instrument that it intends to purchase in
    the future by fixing the price at which it may purchase the instrument. A
    put option gives the purchaser of the option, upon payment of a premium,
    the right to sell, and the writer the obligation to buy, the instrument at
    the exercise price. A Portfolio may purchase a put option to protect its
    holdings in the underlying instrument, or a similar instrument, against a
    substantial decline in the market value of such instrument by giving the
    Portfolio the right to sell the instrument at the option exercise price.
    Possible losses from purchased options cannot exceed the total amount
    invested.

10. FOREIGN EXCHANGE AND FORWARD CURRENCY CONTRACTS: The books and records of
    the Fund are maintained in U.S. dollars. Foreign currency amounts are
    translated into U.S. dollars at the bid prices of such currencies against
    U.S. dollars quoted by a bank. Net realized gains (losses) on foreign
    currency transactions represent net foreign exchange gains (losses) from
    forward foreign currency contracts, disposition of foreign currencies,
    currency gains or losses realized between the trade and settlement dates on
    securities transactions, and the difference between the amount of
    investment income and foreign withholding taxes recorded on the Portfolio's
    books and the U.S. dollar equivalent of amounts actually received or paid.
 
    A forward foreign currency contract is an agreement between two parties to
    buy or sell currency at a set price on a future date. Each Portfolio
    (except the Mid Cap Growth, Domestic Fixed Income, Cash Reserves,
    Mortgage-Backed Securities, and Limited Duration Portfolios) may enter into
    forward foreign currency contracts to protect securities and related
    receivables and payables against future changes in foreign exchange rates.
    Fluctuations in the value of such contracts are recorded as unrealized
    appreciation or depreciation; realized gains or losses, which are disclosed
    in the Statement of Operations, include net gains or losses on contracts
    which have been terminated by settlements. Risks may arise upon entering
    into these contracts from the potential inability of counterparties to meet
    the terms of their contracts and are generally limited to the amount of
    unrealized gain on the contract, if any, at the date of default. Risks may
    also arise from unanticipated movements in the value of the foreign
    currency relative to the U.S. dollar.
 
    At March 31, 1998, the net assets of certain Portfolios were substantially
    comprised of foreign denominated securities and currency. The net assets of
    these Portfolios are presented at the foreign exchange rates and market
    values at the close of the period. The Portfolios do not isolate that
    portion of the results of operations arising as a result of changes in the
    foreign exchange rates from the fluctuations arising from changes in the
    market prices of the securities held at period end. Similarly, the
    Portfolios do not isolate the effect of changes in foreign exchange rates
    from the fluctuations arising from changes in the market prices of
    securities sold during the period. Accordingly, realized and unrealized
    foreign currency gains (losses) are included in the reported net realized
    and unrealized gains (losses) on investment transactions and balances.
    Changes in currency exchange rates will affect the value of and investment
    income from such securities and currency.
 
    Foreign security and currency transactions may involve certain
    considerations and risks not typically associated with those of U.S. dollar
    denominated transactions as a result of, among other factors, the
    possibility of lower levels of governmental supervision and regulation of
    foreign securities markets and the possibility of political or economic
    instability.
 
11. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS: Dividends from net investment
    income, if any, are declared and paid quarterly except for the Municipal
    and PA Municipal Portfolios which are declared and paid monthly, Small Cap
    Value, International Equity, Mid Cap Growth, Mid Cap Value, and Emerging
    Markets Value Portfolios which are declared and paid annually, and Cash
    Reserves Portfolio which are declared daily and paid monthly. Net realized
    capital gains are distributed at least annually. The amount and character
    of income and gains to be distributed are determined in accordance with
    income tax regulations which may differ from generally accepted accounting
    principles. These differences are primarily due to differing book and tax
    treatments in the timing of the recognition of gains or
 
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
 
    losses on securities, forwards and futures, including Post October Losses
    and permanent differences such as gain (loss) on in-kind redemptions (Note
    I), foreign currency transactions and gains on certain equity securities
    designated as issued by "passive foreign investment companies".
 
    Permanent book and tax differences relating to shareholder distributions
    may result in reclassifications to undistributed net investment income
    (loss), undistributed realized net gain (loss) and paid in capital.
 
    Permanent book-tax differences, if any, are not included in ending
    undistributed net investment income (loss) for the purpose of calculating
    net investment income (loss) per share in the Financial Highlights.
 
12. OTHER: Security transactions are accounted for on the date the securities
    are purchased or sold. Costs used in determining realized gains and losses
    on the sale of investment securities are those of specific securities sold.
 
    Dividend income and distributions to shareholders are recorded on the
    ex-dividend date. Interest income is recognized on the accrual basis.
    Discounts and premiums on securities purchased are amortized over their
    respective lives. Securities classified as Value and Mid Cap Growth in the
    Equity, Balanced and Multi-Asset-Class Portfolios are those acquired on the
    basis of measures of value and growth, respectively, deemed appropriate by
    the Investment Adviser. Most expenses of the Fund can be directly
    attributed to a particular Portfolio. Expenses which cannot be directly
    attributed are apportioned among the Portfolios on the basis of their
    relative net assets. Income, expenses (other than class specific expenses)
    and realized and unrealized gains or losses are allocated to each class of
    shares based upon their relative net assets.
 
B. INVESTMENT ADVISORY FEE. Under the terms of an Investment Advisory
Agreement, each Portfolio pays Miller Anderson & Sherrerd, LLP ("MAS" or the
"Adviser"), wholly owned by indirect subsidiaries of Morgan Stanley Dean Witter
& Co., for investment advisory services performed at a fee calculated by
applying a quarterly rate based on an annual percentage rate to each
Portfolio's average daily net assets for the quarter. For the six months ended
March 31, 1998 the investment advisory fees of each of the Portfolios were:

The Adviser has voluntarily agreed to reduce the fees payable to it and, if
necessary, reimburse the Portfolios for certain expenses so that annual
operating expenses will not exceed voluntary expense limitations established
for each class of shares as presented in the table above.
 
C. ADMINISTRATION FEE. MAS serves as Administrator to the Fund pursuant to an
Administration Agreement. Under the agreement, MAS receives an annual fee,
accrued daily and payable monthly, of 0.08% of each Portfolio's average daily
net assets. Chase Global Funds Services Company ("CGFSC") serves as Transfer
Agent to the Fund and provides fund accounting and other services pursuant to a
sub-administration agreement with MAS and receives compensation from MAS for
these services.
 
D. DISTRIBUTOR. MAS Funds Distribution, Inc. ("MASDI" or the "Distributor"), a
wholly owned subsidiary of Morgan Stanley Asset Management

Holdings, Inc., is the distributor for the Fund. MASDI is a limited-purpose
broker/dealer whose only function is to distribute open-end mutual fund shares.
The Distributor provides all classes of shares in each Portfolio with
distribution services pursuant to separate Distribution Plans (the "Plans") in
accordance with Rule 12b-1 under the Investment Company Act of 1940.
 
Under the Plans, the Distributor is entitled to distribution fees and
shareholder servicing fees for Adviser Class and Investment Class shares,
respectively. The distribution fee is an asset-based fee to support
distribution efforts and/or servicing accounts. The Adviser Class of shares
pays an annual service and distribution fee of 0.25% of average net assets of
the class for such services under the 12b-1 plan adopted by the Fund. The
Investment Class of shares pays an annual shareholder servicing fee of 0.15% of
average net assets of the class. The shareholder servicing fee is not a
distribution fee and is used to support the expenses associated with servicing
and maintaining accounts. Both fees are paid directly to MASDI. The
distribution fee may be retained by MASDI if an Adviser Class shareholder
invests directly through MASDI. Usually the fees are paid by MASDI to external
organizations such as 401(k) alliance sponsors, discount brokers and bank trust
departments who distribute MAS Funds to the public.

E. CUSTODY. Morgan Stanley Trust Company (NY) ("MSTC"), an affiliate of the
Fund, serves as custodian for certain of the Fund's assets held outside of the
United States in accordance with a custodian agreement. MSTC is a wholly owned
subsidiary of Morgan Stanley Dean Witter & Co.
 
For the six months ended March 31, 1998, the following Portfolios incurred
custody fees and had amounts payable to MSTC at March 31, 1998:

F. TRUSTEES' FEES. The Fund pays each Trustee, who is not also an officer or
affiliated person, an annual fee plus travel and other expenses incurred in
attending Board meetings. Trustees who are also officers or affiliated persons
receive no remuneration for their service as Trustees.
 
Each eligible Trustee of the Fund who is not an officer or affiliated person,
as defined under the Investment Company Act of 1940, as amended, participates
in the Trustees' Deferred Compensation Plan. Under the Trustees' Deferred
Compensation Plan, such Trustees must defer at least 25% of their fees and may
elect to defer payment up to 100% of their total fees earned as a Trustee of
the Fund. These deferred amounts are invested in the Portfolios selected by the
Trustee. Total trustees fees incurred, for the six months ended March 31, 1998
by the Portfolios were $104,000.
 
Expenses for the six months ended March 31, 1998 include legal fees paid to
Morgan, Lewis & Bockius LLP. A partner of that firm is secretary of the Fund.
