PROSPECTUS                                                     Dated May 1, 1996

                     THE DIVERSIFIED INVESTORS FUNDS GROUP
 
   
     The Diversified Investors Funds Group (the "Trust") is an open-end
management investment company that seeks to provide investors with a broad range
of investment alternatives through its thirteen separate funds (the "Funds").
Each Fund is a separate mutual fund issuing its own shares. Diversified
Investment Advisors, Inc. ("Diversified") is the investment adviser (the
"Adviser") to each Fund and selects, subject to shareholder approval, separate
investment subadvisers (the "Subadvisers") that provide investment advice for
the Funds. The Trust seeks to achieve each Fund's investment objective by
investing all of the investable assets ("Assets") of that Fund in a
corresponding series of Diversified Investors Portfolios (the "Portfolio
Series"). The Portfolio Series (like the Trust) is a diversified, open-end
management investment company with separate series (the "Portfolios") which have
the same investment objectives as the Funds. The thirteen Funds offered for sale
by this Prospectus are as follows:
    
 
        Diversified Investors Money Market Fund
        Diversified Investors High Quality Bond Fund
        Diversified Investors Intermediate Government Bond Fund
        Diversified Investors Government/Corporate Bond Fund
        Diversified Investors High-Yield Bond Fund
        Diversified Investors Balanced Fund
        Diversified Investors Equity Income Fund
   
        Diversified Investors Equity Value Fund
    
        Diversified Investors Growth & Income Fund
        Diversified Investors Equity Growth Fund
        Diversified Investors Special Equity Fund
   
        Diversified Investors Aggressive Equity Fund
    
        Diversified Investors International Equity Fund
 
     UNLIKE OTHER MUTUAL FUNDS WHICH DIRECTLY ACQUIRE AND MANAGE THEIR OWN
PORTFOLIOS OF SECURITIES, THE TRUST SEEKS TO ACHIEVE EACH FUND'S INVESTMENT
OBJECTIVES BY INVESTING ALL OF THAT FUND'S ASSETS IN A CORRESPONDING PORTFOLIO.
SEE "HUB AND SPOKE(R) STRUCTURE" ON PAGE   HEREIN. HUB AND SPOKE(R) IS A
REGISTERED SERVICE MARK OF SIGNATURE FINANCIAL GROUP, INC.
 
     The Trust is designed to meet the long-term investment needs of, and will
be available only as a funding vehicle to, (i) certain employee retirement plans
of for-profit and not-for-profit entities including those having cash or
deferred arrangements and those covering self-employed individuals and
owner-employees (such as 401(k) Plans, 403(b) Plans, 457 Plans, Money Purchase
Plans, Profit Sharing Plans, Simplified Employee Pension Plans and Keogh Plans),
and (ii) qualified personal retirement plans such as IRAs and rollover IRAs
(collectively, "Qualified Investors").
 
     This Prospectus sets forth information about the Trust and the Funds that a
prospective investor should consider before investing. Investors should read
this Prospectus and retain it for future reference. Additional information,
contained in a "Statement of Additional Information," has been filed with the
Securities and Exchange Commission and is available upon request without charge
by calling the Trust at (914) 697-8000. The Statement of Additional Information,
which has the same date as this Prospectus, is incorporated by reference into
this Prospectus.

     THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED
UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE
CONTRARY IS A CRIMINAL OFFENSE.
 
- --------------------------------------------------------------------------------
 
     The Money Market Fund's net asset value per share will fluctuate. Many
money market funds declare a dividend of all investment income each day in order
to maintain a stable net asset value of $1.00 per share. The Money Market Fund
intends to declare dividends of all investment income and to distribute all net
realized capital gains or losses only once a year in December. Undeclared
investment income may cause the Money Market Fund's net asset value per share to
fluctuate. INVESTMENTS IN THE MONEY MARKET FUND ARE NEITHER INSURED NOR
GUARANTEED BY THE U.S. GOVERNMENT.
 
     In pursuing its investment objective, the High-Yield Bond Fund may invest
significantly in lower rated bonds, commonly referred to as "junk bonds". Bonds
of this type are considered to be speculative with regard to the payment of
interest and return of principal. Investments in these types of securities have
special risks and therefore may not be suitable for all investors. Investors
should carefully assess the risks associated with an investment in this Fund.

(1) "Miscellaneous Expenses" have been estimated for the Intermediate Government
    Bond Fund, High-Yield Bond Fund, Equity Value Fund, Aggressive Equity Fund
    and International Equity Fund based on a projected level of average daily
    net assets of $50,000,000 per Fund. There can be no assurance that this
    level of average daily net assets will be achieved for each such Fund. If
    average daily net assets are lower than $50,000,000 for any such Fund,
    "Miscellaneous Expenses" may be a higher percentage of that Fund's average
    daily net assets. "Miscellaneous Expenses" for the Money Market Fund, High
    Quality Bond Fund, Government/Corporate Bond Fund, Balanced Fund, Equity
    Income Fund, Growth & Income Fund, Equity Growth Fund and Special Equity
    Fund are actual for the year ended December 31, 1995 and reflect a voluntary
    reimbursement by Diversified of certain expenses.

(2) Without the voluntary reimbursements and waivers reflected in the table, the
    Total Operating Expenses for the year ended December 31, 1995 would have
    been      % for the Money Market Fund,      % for the High Quality Bond
    Fund,      % for the Government/Corporate Bond Fund,      % for the Balanced
    Fund,      % for the Equity Income Fund,      % for the Growth & Income
    Fund,      % for the Equity Growth Fund and      % for the Special Equity
    Fund.
    
 
(3) The International Equity Fund's total operating expenses may be higher than
    those of many other mutual funds that invest exclusively in U.S. securities,
    since certain costs of operation, such as advisory fees and custodian costs,
    are expected to be higher for a fund investing in foreign securities.
 
                                    EXAMPLE
 
     A shareholder in a Fund would pay the following expenses on a $1,000
investment assuming (i) a 5% annual return on assets and (ii) redemption at the
end of each time period.

     The purpose of the table is to assist investors in understanding the
various costs and expenses that shareholders will bear directly and indirectly.
The expense table and example reflect a voluntary undertaking by Diversified to
waive a portion of the investment advisory fees and administrative services
fees. Without such waiver, the annual administrative services fee would be .30%
for each Fund and the annual investment advisory fee would be .25% for the Money
Market Fund, .35% for the High Quality Bond Fund, .35% for the Intermediate
Government Bond Fund, .35% for the Government/Corporate Bond Fund, .55% for the
High-Yield Bond Fund, .45% for the Balanced Fund, .45% for the Equity Income
Fund, .57% for the Equity Value Fund, .60% for the Growth & Income Fund, .70%
for the Equity Growth Fund, .80% for the Special Equity Fund, .97% for the
Aggressive Equity Fund and .75% for the International Equity Fund.
    
 
     The Trust has adopted a distribution plan (the "Distribution Plan")
pursuant to Rule 12b-1 under the Investment Company Act of 1940, as amended (the
"1940 Act"). Under the Distribution Plan, the Trust may pay the Distributor in
anticipation of, or as reimbursement for, expenses incurred by the Distributor
in connection with the sale of shares of the Funds, a fee not to exceed on an
annual basis 0.25% of the average daily net assets of each Fund. Long term
shareholders may pay more than the economic equivalent of the maximum charges
permitted by the National Association of Securities Dealers, Inc.
 
     For more information on the expenses of the Trust and the Portfolio Series,
see "Management of the Trust and Portfolio Series" herein.
 
     The Trustees of the Trust believe that the aggregate per share expenses of
each Fund and its corresponding Portfolio will be less than or approximately
equal to the expenses which such Fund would incur if the Trust retained the
services of an investment adviser and the assets of such Fund were invested
directly in the types of securities being held by its corresponding Portfolio.

                INVESTMENT OBJECTIVES AND POLICIES OF THE FUNDS
 
     As noted above, the Funds seek to achieve their investment objectives by
investing all of their Assets in Portfolios with investment objectives that
correspond with their own. Each Fund has a different investment objective which
it pursues through the investment policies described below. Since each Fund has
a different investment objective, each can be expected to have different
investment results and to be subject to different market and financial risks.
 
     Diversified has contracted with one or more Subadvisers for each Portfolio
for certain investment advisory services. Diversified and the Subadviser or
Subadvisers for a particular Portfolio are referred to herein collectively as
the "Advisers".
 
     The investment objectives of a Fund or a Portfolio may be changed without
the vote of the holders of the outstanding voting securities of such Fund or
Portfolio. Shareholders of a Fund will receive 30 days' prior written notice of
any change in the investment objective of that Fund or its corre-
 
                                        6
<PAGE>   10
 
sponding Portfolio. There can be no assurance that any of the investment
objectives of the Funds or the Portfolios will be met.
 
   
     MONEY MARKET FUND.  The investment objective of the Money Market Fund and
the Money Market Portfolio is to provide liquidity and as high a level of
current income as is consistent with the preservation of capital. The Money
Market Fund seeks to achieve its investment objective by investing all of its
Assets in the Money Market Portfolio.
    
 
     The Money Market Portfolio invests in high quality short-term money market
instruments. Securities in which the Money Market Portfolio invests may not earn
as high a level of current income as long-term or lower quality securities,
which generally have less liquidity, greater market risk and more fluctuation in
market value.
 
   
     To achieve its investment objective, the Money Market Portfolio invests in
U.S. dollar-denominated short-term money market obligations, including 
securities issued or guaranteed by the U.S. Government or its agencies or 
instrumentalities, certificates of deposit, time deposits, bankers' 
acceptances and other short-term obligations issued by domestic banks and 
foreign banks, and high quality commercial paper and other short-term corporate
obligations, including those with floating or variable rates of interest. In 
addition, the Money Market Portfolio may lend its portfolio securities, enter 
into repurchase agreements and reverse repurchase agreements, and invest in 
securities issued by foreign banks and corporations outside the United States.
The Money Market Portfolio reserves the right to concentrate 25% or more of its
total assets in obligations of domestic banks.
    

     In accordance with Rule 2a-7 under the 1940 Act, the Money Market Portfolio
will maintain a dollar-weighted average portfolio maturity of 90 days or less,
purchase only instruments having remaining maturities of 397 days or less and
invest only in U.S. dollar-denominated securities determined in accordance with
procedures established by the Board of Trustees of the Portfolio Series (the
"Board of Trustees") to present minimal credit risks and which are rated in one
of the two highest rating categories for debt obligations by at least two
nationally recognized statistical rating organizations (an "NRSRO") (or one
NRSRO if the instrument was rated by only one such organization) or, if unrated,
are of comparable quality as determined in accordance with procedures
established by the Board of Trustees (collectively, "Eligible Securities").
 
     Eligible Securities include "First Tier Securities" and "Second Tier
Securities". First Tier Securities include those that possess a rating in the
highest category in the case of a single-rated security or at least two ratings
in the highest rating category in the case of multiple-rated securities or, if
the securities do not possess a rating, are determined to be of comparable
quality by the Advisers pursuant to the guidelines adopted by the Board of
Trustees. All other Eligible Securities are Second Tier Securities. The Money
Market Portfolio will invest at least 95% of its total assets in First Tier
Securities.
 
   
     The NRSROs currently rating instruments of the type the Portfolio may
purchase are Moody's Investors Service, Inc., Standard & Poor's Ratings Group,
Duff & Phelps, Inc., Fitch Investors Service, Inc., IBCA Limited and IBCA Inc.
and Thomson BankWatch, Inc., and their rating criteria are described in the
Appendix to the Statement of Additional Information. The Statement of Additional
Information contains further information concerning the rating criteria and
other requirements governing the Portfolio's investments, including information
relating to the treatment of securities subject to a tender or demand feature
and securities deemed to possess a rating based on comparable rated securities
of the same issuer.
    
 
     In addition, the Portfolio will not invest more than 5% of its total assets
in the securities (including the securities collateralizing a repurchase
agreement) of, or subject to puts (including letters of credit, guaranties or
other credit support) issued by, a single issuer, except that (i) the Portfolio
may invest more than 5% of its total assets in a single issuer for a period of
up to three business days in certain limited circumstances, (ii) the Portfolio
may invest in obligations issued or guaranteed by the U.S. Government without
any such limitation, and (iii) the limitation with respect to puts does not
apply to unconditional puts if no more than 10% of the Portfolio's total assets
is invested in securities
 
                                        7
<PAGE>   11
 
issued or guaranteed by the issuer of the unconditional put. Investments in
Second Tier Securities will be limited to 5% of the Portfolio's total assets,
with the investment in any one such issuer being limited to no more than the
greater of 1% of the Portfolio's total assets or $1,000,000. As to each
security, these percentages are measured at the time the Portfolio purchases the
security.
 
     The Money Market Portfolio seeks to achieve its investment objective
through investments in the following types of U.S. dollar-denominated money
market instruments.
 
          BANK OBLIGATIONS.  The Portfolio may invest in U.S. dollar-denominated
     certificates of deposit, time deposits, bankers' acceptances and other
     short-term obligations issued by domestic banks and domestic branches and
     subsidiaries of foreign banks. Certificates of deposit are certificates
     evidencing the obligation of a bank to repay funds deposited with it for a
     specified period of time. Such instruments include Yankee Certificates of
     Deposit, which are certificates of deposit denominated in U.S. dollars and
     issued in the United States by the domestic branch of a foreign bank. Time
     deposits are non-negotiable deposits maintained in a banking institution
     for a specified period of time at a stated interest rate. Time deposits
     which may be held by the Portfolio are not insured by the Federal Deposit
     Insurance Corporation or any other agency of the U.S. Government. The
     Portfolio will not invest more than 10% of the value of its net assets in
     time deposits maturing in longer than seven days and other instruments
     which are illiquid or not readily marketable. The Portfolio may also invest
     in certificates of deposit and time deposits issued by foreign banks
     outside the United States.
 
          The Portfolio may also invest in bankers' acceptances and other
     short-term obligations. Bankers' acceptances are credit instruments
     evidencing the obligation of a bank to pay a draft drawn on it by a
     customer. These instruments reflect the obligation both of the bank and of
     the drawer to pay the face amount of the instrument upon maturity. The
     other short-term obligations may include uninsured, direct obligations
     which have either fixed, floating or variable interest rates.
 
          To the extent the Portfolio's investments are concentrated in the
     banking industry, the Portfolio will have correspondingly greater exposure
     to the risk factors which are characteristic of such investments. Sustained
     increases in interest rates can adversely affect the availability or
     liquidity and cost of capital funds for a bank's lending activities, and a
     deterioration in general economic conditions could increase the exposure to
     credit losses. In addition, the value of and the investment return on the
     Fund's shares could be affected by economic or regulatory developments in
     or related to the banking industry, which industry also is subject to the
     effects of the concentration of loan portfolios in leveraged transactions
     and in particular businesses, and competition within the banking industry,
     as well as with other types of financial institutions. The Portfolio,
     however, will seek to minimize its exposure to such risks by investing only
     in debt securities which are determined to be of high quality.
 
          U.S. GOVERNMENT AND AGENCY SECURITIES.  Securities issued or
     guaranteed by the U.S. Government or its agencies or instrumentalities
     include U.S. Treasury securities, which differ only in their interest
     rates, maturities and times of issuance. Treasury Bills have initial
     maturities of one year or less; Treasury Notes have initial maturities of
     one to ten years; and Treasury Bonds generally have initial maturities of
     greater than ten years. Some obligations issued or guaranteed by U.S.
     Government agencies and instrumentalities, for example, Government National
     Mortgage Association pass-through certificates, are supported by the full
     faith and credit of the U.S. Treasury; others, such as those of the Federal
     Home Loan Banks, by the right of the issuer to borrow from the Treasury;
     others, such as those issued by the Federal National Mortgage Association,
     by discretionary authority of the U.S. Government to purchase certain
     obligations of the agency or instrumentality; and others, such as those
     issued by the Student Loan Marketing Association, only by the credit of the
     agency or instrumentality. While the U.S. Government provides financial
     support to such U.S. Government-sponsored agencies or instrumentalities, no
     assurance can be given that it will always do so, since it is not so
     obligated by law. The Portfolio
 
                                        8
<PAGE>   12
 
     will invest in such securities only when the Advisers are satisfied that
     the credit risk with respect to the issuer is minimal.
 
          COMMERCIAL PAPER.  Commercial paper consists of short-term, unsecured
     promissory notes issued to finance short-term credit needs. The commercial
     paper purchased by the Portfolio will consist only of U.S.
     dollar-denominated direct obligations issued by domestic and foreign
     entities. The other corporate obligations in which the Portfolio may invest
     consist of high quality, U.S. dollar-denominated short-term bonds and notes
     issued by domestic corporations.
 
          The Portfolio may invest in commercial paper issued by major
     corporations in reliance on the exemption from registration afforded by
     Section 3(a)(3) of the Securities Act of 1933, as amended (the "1933 Act").
     Such commercial paper may be issued only to finance current transactions
     and must mature in nine months or less. Trading of such commercial paper is
     conducted primarily by institutional investors through investment dealers,
     and individual investor participation in the commercial paper market is
     very limited.
 
          UNSECURED PROMISSORY NOTES.  The Portfolio also may purchase unsecured
     promissory notes ("Notes") which are not readily marketable and have not
     been registered under the 1933 Act, provided such investments are
     consistent with the Portfolio's investment objective. The Notes purchased
     by the Portfolio will have remaining maturities of 13 months or less and
     will be deemed by the Board of Trustees, or by the Advisers on behalf of
     the Board, to present minimal credit risks and will meet the quality
     criteria set forth above. The Portfolio will invest no more than 10% of its
     net assets in such Notes and in other securities that are not readily
     marketable (which securities would include floating and variable rate
     demand obligations as to which the Portfolio cannot exercise the demand
     feature described in the Statement of Additional Information and as to
     which there is no secondary market).
 
          RESTRICTED SECURITIES.  The Portfolio may invest in securities that
     are subject to legal or contractual restrictions on resale. These
     securities may be illiquid and, thus, the Portfolio may not purchase them
     to the extent that more than 10% of the value of its net assets would be
     invested in illiquid securities. However, if a substantial market of
     qualified institutional buyers develops pursuant to Rule 144A under the
     1933 Act for such securities held by the Portfolio, the Portfolio intends
     to treat such securities as liquid securities in accordance with procedures
     approved by the Board of Trustees. To the extent that for a period of time
     qualified institutional buyers cease purchasing such restricted securities
     pursuant to Rule 144A, the Portfolio's investing in such securities may
     have the effect of increasing the level of illiquidity in the Portfolio
     during such period.
 
          REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS.  Repurchase
     agreements involve the acquisition by the Portfolio of an underlying debt
     instrument subject to an obligation of the seller to repurchase, and the
     Portfolio to resell, the instrument at a fixed price usually not more than
     one week after its purchase. The Portfolio's custodian or a sub-custodian
     will have custody of securities acquired by the Portfolio under a
     repurchase agreement.
 
          Repurchase agreements may be entered into for the Portfolio with
     sellers, which are usually member banks of the Federal Reserve System or
     member firms of the New York Stock Exchange (or a subsidiary thereof). Such
     transactions afford an opportunity for the Portfolio to earn a return on
     available cash with minimal market risk. Certain costs may be incurred by
     the Portfolio in connection with the sale of the securities if the seller
     does not repurchase them in accordance with the repurchase agreement. In
     addition, if bankruptcy proceedings are commenced with respect to the
     seller of the securities, realization on the securities by the Portfolio
     may be delayed or limited. Repurchase agreements are considered
     collateralized loans under the 1940 Act.
 
          The Portfolio may borrow funds for temporary or emergency purposes,
     such as meeting larger than anticipated redemption requests, and not for
     leverage, and by agreeing to sell portfolio securities to financial
     institutions such as banks and broker-dealers and to repurchase them at a
 
                                        9
<PAGE>   13
 
     mutually agreed date and price (a "reverse repurchase agreement"). At the
     time the Portfolio enters into a reverse repurchase agreement it will place
     in a segregated custodial account cash, U.S. Government securities or
     high-grade debt obligations having a value equal to the repurchase price,
     including accrued interest. Reverse repurchase agreements involve the risk
     that the market value of the securities sold by the Portfolio may decline
     below the repurchase price of those securities. Reverse repurchase
     agreements are considered to be borrowings by the Portfolio.
 
   
          FOREIGN SECURITIES.  The Portfolio may invest in U.S.
     dollar-denominated foreign securities issued outside the United States,
     such as obligations of foreign branches and subsidiaries of domestic banks
     and foreign banks, including Eurodollar certificates of deposit, Eurodollar
     time deposits and Canadian time deposits, commercial paper of Canadian and
     other foreign issuers, and U.S. dollar-denominated obligations issued or
     guaranteed by one or more foreign governments or any of their agencies or
     instrumentalities. Foreign securities may represent a greater degree of
     risk than do securities of domestic issuers due to possible exchange rate
     fluctuations, possible exchange controls, less publicly available
     information, more volatile markets, less securities regulation, less
     favorable tax provisions (including possible withholding taxes), changes in
     governmental administration or economic or monetary policy (in the United
     States or abroad), war or expropriation. For a complete description of
     foreign securities the Portfolio may purchase, see "Investment Policies" in
     the Statement of Additional Information.
 
          CERTAIN OTHER OBLIGATIONS.  In order to allow for investments in new
     instruments that may be created in the future, upon the Trust supplementing
     this Prospectus, the Portfolio may invest in obligations other than those
     listed previously, provided such investments are consistent with the
     Portfolio's investment objective, policies and restrictions.
    
 
          The Statement of Additional Information includes a discussion of
     additional investment techniques such as zero coupon obligations, variable
     rate and floating rate securities, participation interests, guaranteed
     investment contracts and when-issued and forward commitment securities. The
     Statement of Additional Information also includes a discussion of
     nonfundamental investment policies, as well as a listing of specific
     investment restrictions which constitute fundamental policies of the Fund
     or the Portfolio and cannot be changed without the approval of the holders
     of a "majority of the outstanding voting securities" (as defined in the
     1940 Act) of the Fund or the Portfolio, respectively. See "Investment
     Restrictions" in the Statement of Additional Information.
 
   
     HIGH QUALITY BOND FUND.  The investment objective of the High Quality Bond
Fund and the High Quality Bond Portfolio is to provide as high a level of
current income as is consistent with the preservation of capital. The yield of
the High Quality Bond Fund normally is expected to be higher than a money market
fund but lower than a longer-term or lower quality bond fund. Unlike a money
market fund, the Fund does not seek to maintain a stable net asset value and may
not be able to return dollar-for-dollar the money invested. The High Quality
Bond Fund seeks to achieve its investment objective by investing all of its
Assets in the High Quality Bond Portfolio.
    
 
     The High Quality Bond Portfolio pursues its investment objective by
investing at least 65% of its assets under normal circumstances in high quality
debt securities with short and intermediate maturities (including repurchase
agreements and reverse repurchase agreements).
 
     The Advisers attempt to maintain the Portfolio's "duration" between one and
four years, which means that the Portfolio's overall sensitivity to interest
rates should be slightly more than that of bonds and notes with remaining
average maturities from one to four years. The Portfolio's dollar-weighted
average maturity (or dollar-weighted average life in the case of asset-backed
and mortgage-backed securities) may be longer than four years from time to time,
but will not exceed five years under normal conditions. The Portfolio may hold
individual securities with remaining maturities of up to thirty years.
 
     The Portfolio seeks consistency of return with minimal exposure to negative
total returns on an annual basis. The Advisers' strategy is to position the
Portfolio in those high quality sectors of the fixed income market that offer
the most attractive yields on a risk-adjusted basis. The duration of the
 
                                       10
<PAGE>   14
 
Portfolio will be a function of the security and sector selection process and
market conditions in general. Since the value of fixed income securities
generally fluctuates inversely with changes in interest rates, the value of
securities held by the Fund will tend to decline during periods of rising
interest rates.
 
   
     The Advisers normally will select only securities having a minimum
long-term quality rating of A-by Standard & Poor's Ratings Group ("S&P") or A3
by Moody's Investors Service, Inc. ("Moody's") will at the time of purchase, or,
in the case of instruments that are not rated or are rated by other agencies
(i.e., Fitch Investors Service, Inc., Duff & Phelps, Inc., etc.) are deemed by
the Advisers to be of similar quality. Money market securities will have a
minimum short-term rating of at least A-1 or P-1 by S&P or Moody's,
respectively, or an equivalent rating by other agencies. The Portfolio may
continue to hold such securities if their ratings are reduced after purchase.
    
 
     The High Quality Bond Portfolio seeks to achieve its investment objective
through investments in the following types of instruments.
 
   
          U.S. GOVERNMENT AND AGENCY SECURITIES.  The Portfolio may invest in
     U.S. Government securities and securities issued or guaranteed by its
     agencies or instrumentalities. These securities have varying degrees of
     government backing. They may be backed by the credit of the government as a
     whole or only by the issuing agency. For example, securities issued by the
     Federal Home Loan Mortgage Corporation and the Federal National Mortgage
     Association are supported by the agency's right to borrow money from the
     U.S. Treasury under certain circumstances. U.S. Treasury bonds, notes and
     bills, and some agency securities, such as those issued by the Government
     National Mortgage Association, are backed by the full faith and credit of
     the U.S. Government as to payment of principal and interest and are the
     highest quality government securities. There is no assurance that the U.S.
     Government will support obligations of its agencies unless it is required
     to do so by law. The Fund itself, and its share price and yield, are not
     guaranteed by the U.S. Government. For additional information on U.S.
     Government securities, see the Statement of Additional Information.
    
 
          The Portfolio may invest a portion of its assets in short-term U.S.
     Government securities with remaining maturities of one year or less and
     repurchase agreements relating thereto. When the Advisers believe market
     conditions warrant a temporary defensive position, the Portfolio may invest
     up to 100% of its assets in these instruments.
 
   
          CORPORATE BONDS.  The Portfolio may purchase public or private
     corporate bonds, issued by domestic or foreign issuers, that meet the
     Portfolio's minimum credit quality criteria at the time of purchase. The
     corporate bond market is customarily subdivided into several segments,
     which include industrial, public utility, rail and transportation bonds,
     and bonds issued by banks and other financial institutions.
 
          YANKEE BONDS AND EURODOLLAR BONDS.  The Portfolio may purchase Yankee
     and Eurodollar issues that meet its minimum credit quality standards.
     Yankee issues are dollar denominated bonds issued in the United States
     market by foreign issuers and are, therefore, subject to SEC regulations.
     Issuers of yankee bonds include, among others, foreign corporations,
     foreign governments and agencies, and multilateral lending institutions.
     Eurodollar bonds are fixed income securities that are denominated in
     dollars, are underwritten by an international syndicate, and are sold upon
     issuance to non-U.S. investors. U.S.-based investors may purchase
     eurodollar bonds in the secondary market after a seasoning period.
     Eurodollar bonds are not subject to SEC regulations.
 
          MORTGAGE PASS-THROUGHS AND COLLATERALIZED MORTGAGE OBLIGATIONS.  The
     Portfolio may purchase mortgage and mortgage-related securities such as
     pass-throughs, collateralized mortgage obligations, and mortgage
     derivatives that meet the Portfolio's minimum credit quality criteria
     (collectively, "Mortgage Securities"). Mortgage pass-throughs are
     securities that pass through to investors an undivided interest in a pool
     of underlying mortgages. These may be issued or
    
 
                                       11
<PAGE>   15
 
     guaranteed by U.S. government agencies, or may consist of whole loans
     originated and issued by private limited purpose corporations or conduits.
 
          Collateralized mortgage obligation bonds and mortgage derivatives are
     obligations of special purpose corporations that are collateralized or
     supported by mortgages or mortgage securities such as pass throughs.
     Principal prepayments on the underlying mortgages or loans may cause the
     Mortgage Securities to be retired substantially earlier than their stated
     maturities or final distribution dates, resulting in a loss to the
     Portfolio of all or part of the premium, if any, which the Portfolio may
     pay when investing in Mortgage Securities.
 
   
          ASSET-BACKED SECURITIES.  The Portfolio may purchase public or private
     asset-backed securities of various types, which are fixed income securities
     that are collateralized or "backed" by installment receivables (usually
     consumer loans) for which some type of credit enhancement is provided.
     Asset-backed securities that are eligible for purchase by the Portfolio
     include securities backed by automobile receivables, credit card
     receivables, home equity loans, manufactured housing loans, business and
     recreational vehicle loans, computer leases, and agricultural equipment
     loans.
 
          SHORT-TERM INSTRUMENTS.  Cash, commercial paper, short-term
     obligations, repurchase agreements or other forms of debt securities may be
     held to provide a reserve for future purchases of securities during periods
     of unusual market conditions or in order to reduce volatility, or as a
     temporary defensive measure when the Advisers determine securities markets
     to be overvalued. The Portfolio limits its short-term investments to those
     U.S. dollar-denominated instruments which are determined by or on behalf of
     the Board of Trustees to present minimal credit risks and which are of
     "high quality" as determined by a major rating service (i.e., rated P-1 by
     Moody's or A-1 by S&P) or, in the case of instruments which are not rated,
     are of comparable quality pursuant to procedures established by the Board
     of Trustees. Investments in high quality short-term instruments may, in
     many circumstances, result in a lower yield than would be available from
     investments in instruments with a lower quality or longer term.
 
          REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS.  The High
     Quality Bond Portfolio may enter into repurchase agreements and reverse
     repurchase agreements. See "Repurchase Agreements and Reverse Repurchase
     Agreements" under Money Market Fund. The Portfolio may borrow funds for
     temporary or emergency purposes, such as meeting larger than anticipated
     redemption requests, and not for leverage.
 
          RESTRICTED SECURITIES.  The Portfolio may purchase securities in the
     United States that are not registered for sale under federal securities
     laws but which can be resold to institutions under SEC Rule 144A. Provided
     that a dealer or institutional trading market in such securities exists,
     these restricted securities are treated as exempt from the Portfolio's 15%
     limit on illiquid securities. Under the supervision of the Board of
     Trustees, the Advisers determine the liquidity of restricted securities
     and, through reports from the Advisers, the Board of Trustees will monitor
     trading activity in restricted securities. Because Rule 144A is relatively
     new, it is not possible to predict how these markets will develop. If
     institutional trading in restricted securities were to decline, the
     liquidity of the Portfolio could be adversely affected.
 
          OPTIONS AND FUTURES CONTRACTS.  The Portfolio may buy and sell options
     and futures contracts to manage its exposure to changing interest rates and
     securities prices. Some options and futures strategies, including selling
     futures, buying puts, and writing calls, hedge the Portfolio's investments
     against price fluctuations. Other strategies, including buying futures,
     writing puts and buying calls, tend to increase market exposure. The
     Portfolio may invest in options (including over-the-counter options) and
     futures contracts based on any type of security or index related to its
     investments.
    
 
          Options and futures can be volatile investments, and involve certain
     risks. If the Advisers apply a hedge at an inappropriate time or judge
     interest rates incorrectly, options and futures
 
                                       12
<PAGE>   16
 
     strategies may lower the Fund's return. The costs of hedging are not
     reflected in the Fund's yield but are reflected in the Fund's total return.
     The Fund could also experience losses if the Portfolio's options and
     futures positions were poorly correlated with its other investments, or if
     it could not close out its positions because of an illiquid secondary
     market.
 
          The Portfolio currently does not intend to engage in the writing of
     options, except for the purpose of terminating an existing position or
     under the limited circumstances described in the Statement of Additional
     Information. Nevertheless, the Portfolio has the authority to write options
     and may do so in the future if the Advisers determine that such
     transactions are in the best interests of the Portfolio.
 
          DELAYED DELIVERY TRANSACTIONS.  In order to help ensure the
     availability of suitable securities for the Portfolio, the Advisers may
     purchase securities for the Portfolio on a "when-issued" or on a "forward
     delivery" basis, which means that the obligations would be delivered to the
     Portfolio at a future date beyond customary settlement time. Under normal
     circumstances, the Portfolio would take delivery of such securities. In
     general, the Portfolio would not pay for the securities until they are
     received, and would not start earning interest on the obligations until the
     contractual settlement date. While awaiting delivery of the obligations
     purchased on such basis, the Portfolio would establish a segregated account
     consisting of cash, cash equivalents or high grade liquid debt securities
     equal to the amount of its commitments to purchase "when-issued"
     securities. An increase in the percentage of the Portfolio's assets
     committed to the purchase of securities on a "when-issued" basis may
     increase the volatility of the Fund's net asset value.
 
          OTHER INVESTMENTS AND INVESTMENT TECHNIQUES.  The Portfolio may also
     utilize the following investments and investment techniques and practices:
     investments in foreign securities, investments in securities denominated in
     foreign currencies, options on futures contracts, foreign currency exchange
     transactions and options on foreign currencies. The Portfolio does not
     intend to utilize any of these investments or practices to the extent of
     more than 5% of its assets. See the Statement of Additional Information for
     further information.
 
     INTERMEDIATE GOVERNMENT BOND FUND.  The investment objective of the
Intermediate Government Bond Fund is to provide as high a level of current
income as is consistent with the preservation of capital. The yield of the
Intermediate Government Bond Fund normally is expected to be higher than a money
market fund but lower than a longer-term or lower quality bond fund. The
Intermediate Government Bond Fund pursues its investment objective by investing
all of its Assets in the Intermediate Government Bond Portfolio.
 
     The Intermediate Government Bond Portfolio pursues its investment objective
by investing in high quality U.S. Government obligations and high quality
short-term obligations (including repurchase agreements and reverse repurchase
agreements). The Intermediate Government Bond Portfolio normally will invest at
least 65% of its assets in U.S. Government obligations. The Advisers attempt to
maintain the Intermediate Government Bond Portfolio's "duration" between one and
five years, which means that the Intermediate Government Bond Portfolio's
overall sensitivity to interest rates should be similar to that of bonds and
notes with remaining average maturities from one to five years. The Intermediate
Government Bond Portfolio's dollar-weighted average maturity (or dollar-weighted
average life in the case of mortgage-backed securities) may be longer than five
years from time to time, but will not exceed ten years or be less than 3 years
under normal conditions. The Intermediate Government Bond Portfolio may hold
individual securities with remaining maturities of up to thirty years.
 
     Since the value of fixed-income securities generally fluctuates inversely
with changes in interest rates, the duration of the Intermediate Government Bond
Portfolio will vary to reflect the Advisers' assessments of prospective changes
in interest rates. The Advisers' strategy will be to adjust the duration of the
Intermediate Government Bond Portfolio so that the Intermediate Government Bond
Portfolio may benefit from relative price appreciation when interest rates
decline and may protect capital value when interest rates rise. The success of
this strategy will depend on the Advisers' ability to
 
                                       13
<PAGE>   17
 
manage the Intermediate Government Bond Portfolio through changes in interest
rates, and there is a risk that the value of the securities held by the
Intermediate Government Bond Portfolio will decline.
 
     The following is a discussion of the various investments of and techniques
employed by the Intermediate Government Bond Portfolio. Additional information
about the investment policies of the Intermediate Government Bond Portfolio
appears under "Diversified Investors Portfolios" in the Statement of Additional
Information.
 
   
          U.S. GOVERNMENT AND AGENCY SECURITIES.  The Intermediate Government
     Bond Portfolio may invest in U.S. Government securities. See "U.S.
     Government and Agency Securities" above under Money Market Fund. The
     Intermediate Government Bond Portfolio may invest a portion of its assets
     in short-term U.S. Government securities with remaining maturities of one
     year or less and repurchase agreements relating thereto. When the Advisers
     believe market conditions warrant a temporary defensive position, the
     Portfolio may invest up to 100% of its assets in these instruments.
 
          SHORT-TERM INSTRUMENTS.  Cash, commercial paper, short-term
     obligations, repurchase agreements or other forms of debt securities may be
     held to provide a reserve for future purchases of securities during periods
     of unusual market conditions or in order to reduce volatility, or as a
     temporary defensive measure when the Advisers determine securities markets
     to be overvalued. See "Short Term Instruments" above under High Quality
     Bond Fund.
 
          REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS.  Repurchase
     agreements and reverse repurchase agreements may be entered into by the
     Intermediate Government Bond Portfolio. See "Repurchase Agreements and
     Reverse Repurchase Agreements" under Money Market Fund. The Intermediate
     Government Bond Portfolio may borrow funds for temporary or emergency
     purposes, such as meeting larger than anticipated redemption requests, and
     not for leverage.
 
          RESTRICTED SECURITIES.  The Intermediate Government Bond Portfolio may
     invest not more than 15% of its net assets in securities that are subject
     to legal or contractual restrictions on resale. See "Restricted Securities"
     above under Money Market Fund.
 
          OPTIONS AND FUTURES CONTRACTS.  The Intermediate Government Bond
     Portfolio may buy and sell options and futures contracts to manage its
     exposure to changing interest rates and securities prices. See "Options and
     Futures Contracts" above under High Quality Bond Fund.
 
          The Intermediate Government Bond Portfolio currently does not intend
     to engage in the writing of options, except for the purpose of terminating
     an existing position or under the limited circumstances described under
     "Diversified Investors Portfolios" in the Statement of Additional
     Information. Nevertheless, the Intermediate Government Bond Portfolio has
     the authority to write options and may do so in the future if the Advisers
     determine that such transactions are in the best interests of the
     Intermediate Government Bond Portfolio.
 
          DELAYED DELIVERY TRANSACTIONS.  In order to help ensure the
     availability of suitable securities for the Intermediate Government Bond
     Portfolio, the Advisers may purchase securities for the Intermediate
     Government Bond Portfolio on a "when-issued" or on a "forward delivery"
     basis, which means that the obligations would be delivered to the
     Intermediate Government Bond Portfolio at a future date beyond customary
     settlement time. See "Delayed Delivery Transactions" above under the High
     Quality Bond Fund.
 
          OTHER INVESTMENT AND INVESTMENT TECHNIQUES.  The Intermediate
     Government Bond Portfolio may, in each case up to 5% of the Portfolio's
     assets, also utilize the following investments and investment techniques
     and practices: investments in foreign securities, options on futures
     contracts, foreign currency exchange transactions and options on foreign
     currencies. See "Diversified Investors Portfolios" in the Statement of
     Additional Information for further information.

<PAGE>   18
 
     GOVERNMENT/CORPORATE BOND FUND.  The investment objective of the
Government/Corporate Bond Fund and the Government/Corporate Bond Portfolio is to
achieve the maximum total return. The Government/Corporate Bond Fund yield
normally is expected to be higher than a money market fund but lower than a
longer-term or lower quality bond fund. The Government/Corporate Bond Fund seeks
to achieve its investment objective by investing all of its Assets in the
Government/Corporate Bond Portfolio.
 
     The Government/Corporate Bond Portfolio pursues its investment objective by
investing in investment grade debt securities, U.S. Government obligations,
including U.S. Government agency and instrumentality obligations and
collateralized mortgage obligations guaranteed by these agencies and
instrumentalities, and high quality short-term obligations (including repurchase
agreements and reverse repurchase agreements). At least 65% of the Portfolio's
assets is invested in U.S. Government securities, corporate bonds and short-term
instruments.
 
     The Advisers attempt to maintain the Government/Corporate Bond Portfolio's
"duration" between three and ten years, which means that the Portfolio's overall
sensitivity to interest rates should be slightly more than that of bonds and
notes with remaining average maturities from three to fifteen years. The
Government/Corporate Bond Portfolio's dollar-weighted average maturity (or
dollar-weighted average life in the case of mortgage-backed securities) may be
longer than fifteen years from time to time, but will not exceed thirty years
under normal conditions. The Government/Corporate Bond Portfolio may hold
individual securities with remaining maturities of up to thirty years.
 
     Since the value of fixed income securities generally fluctuates inversely
with changes in interest rates, the duration of the Portfolio will vary to
reflect the Advisers' assessments of prospective changes in interest rates. The
Advisers' strategy will be to adjust the duration of the Portfolio so that the
Government/Corporate Bond Portfolio may benefit from relative price appreciation
when interest rates decline and may protect capital value when interest rates
rise. The success of this strategy will depend on the Advisers' ability to
manage the Portfolio through changes in interest rates, and there is a risk that
the value of the securities held by the Portfolio will decline.
 
     The Government/Corporate Bond Portfolio seeks to achieve its investment
objective through investments in the following types of instruments.
 
   
          U.S. GOVERNMENT AND AGENCY SECURITIES.  The Government/Corporate Bond
     Portfolio may invest in U.S. Government securities. See "U.S. Government
     and Agency Securities" above under Money Market Fund. The Portfolio may
     invest a portion of its assets in short-term U.S. Government securities
     with remaining maturities of one year or less and repurchase agreements
     relating thereto. When the Advisers believe market conditions warrant a
     temporary defensive position, the Portfolio may invest up to 100% of its
     assets in these instruments.
 
          CORPORATE BONDS.  The Government/Corporate Bond Portfolio may purchase
     debt securities of United States corporations only if they carry a rating
     of at least Baa from Moody's or BBB from S&P or which, if not rated by
     these rating agencies, are judged by the Advisers to be of comparable
     quality. Securities rated Baa by Moody's or BBB by S&P may have speculative
     characteristics. Changes in economic condition or other circumstances are
     more likely to lead to a weakened capacity to make principal and interest
     payments than is the case for higher grade securities. See the Appendix to
     the Statement of Additional Information for an explanation of these
     ratings.
 
          FOREIGN SECURITIES.  The Government/Corporate Bond Portfolio may
     invest in securities of foreign issuers. The Fund's investments in unlisted
     foreign securities are subject to the overall restrictions applicable to
     investments in illiquid securities. The Advisers do not intend to
     concentrate more than 25% of such foreign investments in any one type of
     instrument or in any foreign country. Foreign securities may represent a
     greater degree of risk than do securities of domestic issuers due to
     possible exchange rate fluctuations, possible exchange controls, less
     publicly available information, more volatile markets, less securities
     regulation, less favorable tax provisions (including possible withholding
     taxes), changes in governmental administration or
    
 
                                       15

     economic or monetary policy (in the United States or abroad), war or
     expropriation. Forward foreign currency exchange contracts may also be
     entered into for the purchase or sale of foreign currency solely for
     hedging purposes against adverse rate changes. A currency exchange contract
     allows a definite price in dollars to be fixed for foreign securities that
     have been purchased or sold (but not settled) for the Portfolio. Entering
     into such exchange contracts may result in the loss of all or a portion of
     the benefits which otherwise could have been obtained from favorable
     movements in exchange rates. In addition, entering into such contracts
     means incurring certain transaction costs and bearing the risks of
     incurring losses if rates do not move in the direct anticipated.
 
   
          SHORT-TERM INSTRUMENTS.  Cash, commercial paper, short-term
     obligations, repurchase agreements, bank certificates of deposit or other
     forms of debt securities may be held to provide a reserve for future
     purchases of securities, during periods of unusual market conditions or in
     order to reduce volatility, or as a temporary defensive measure when the
     Advisers determine securities markets to be overvalued. See "Short Term
     Instruments" above under High Quality Bond Fund.
 
        REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS.  The
     Government/Corporate Bond Portfolio may enter into repurchase agreements
     and reverse repurchase agreements. See "Repurchase Agreements and Reverse
     Repurchase Agreements" under Money Market Fund. The Portfolio may borrow
     funds for temporary or emergency purposes, such as meeting larger than
     anticipated redemption requests, and not for leverage.
 
          RESTRICTED SECURITIES.  The Government/Corporate Bond Portfolio may
     invest not more than 15% of its net assets in securities that are subject
     to legal or contractual restrictions on resale. See "Restricted Securities"
     above under High Quality Bond Fund.
 
          OPTIONS AND FUTURES CONTRACTS.  The Government/Corporate Bond Series
     may buy and sell options and futures contracts to manage its exposure to
     changing interest rates and securities prices. See "Options and Futures
     Contracts" above under High Quality Bond Fund.
    
 
          The Portfolio currently does not intend to engage in the writing of
     options, except for the purpose of terminating an existing position or
     under the limited circumstances described in the Statement of Additional
     Information.
 
          Nevertheless, the Portfolio has the authority to write options and may
     do so in the future if the Advisers determine that such transactions are in
     the best interests of the Portfolio.
 
   
          DELAYED DELIVERY TRANSACTIONS.  In order to help ensure the
     availability of suitable securities for the Government/Corporate Bond
     Portfolio, the Advisers may purchase securities for the Portfolio on a
     "when-issued" or on a "forward delivery" basis which means that the
     securities would be delivered to the Portfolio at a future date beyond
     customary settlement times. See "Delayed Delivery Transactions" above under
     High Quality Bond Fund.
 
          OTHER INVESTMENTS AND INVESTMENT TECHNIQUES.  The Government/Corporate
     Bond Portfolio may also utilize the following investments and investment
     techniques and practices: options on futures contracts and options on
     foreign currencies. The Portfolio does not intend to utilize any of these
     investments or techniques to the extent of more than 5% of its assets. See
     the Statement of Additional Information for further information.
 
     HIGH-YIELD BOND FUND.  The investment objective of the High-Yield Bond Fund
is to seek a high level of current income. The High Yield Bond Fund seeks to
achieve its investment objective by investing all of its Assets in the
High-Yield Bond Portfolio.
    
 
     The High-Yield Bond Portfolio pursues its investment objective by investing
in a diversified portfolio consisting primarily of high-yielding, fixed-income
and zero coupon securities, such as bonds, debentures and notes, convertible
securities and preferred stocks. The Portfolio may invest all or a substantial
portion of its assets in lower-rated debt securities, commonly referred to as
"junk bonds". Such investments may include foreign securities and obligations
issued or guaranteed by the
 
                                       16
<PAGE>   20
   
U.S. government, any of its states or territories, any foreign government or any
of their respective subdivisions, agencies or instrumentalities.
    
 
     The High-Yield Bond Portfolio normally will invest at least 65% of its
assets in high-yielding, income producing debt securities and preferred stocks,
including convertible and zero coupon securities. Zero coupon securities are
debt securities that pay no cash income but are sold at substantial discounts
from their fact value. Certain zero coupon securities also are sold at
substantial discounts but provide for the commencement of regular interest
payments at a deferred date. The Portfolio may invest up to 35% of its assets in
equity securities, including common stocks, warrants and rights.
 
   
     Lower-rated debt securities usually are defined as securities rated Ba or
lower by Moody's or BB or lower by S&P. Lower-rated debt securities are
considered speculative and involve greater risk of default or price changes due
to changes in the issuer's creditworthiness than higher-rated securities and are
more sensitive to changes in the issuer's capacity to pay. This is an aggressive
approach to income investing. The 1980s saw a dramatic increase in the use of
lower-rated debt securities to finance highly leveraged corporate acquisitions
and restructurings. Past experience may not provide an accurate indication of
future performance of lower-rated debt securities, especially during period of
economic recession. In fact, from 1989 to 1991, the percentage of lower-rated
debt securities that defaulted rose significantly above prior levels.
    
 
     Lower-rated debt securities may be thinly traded, which can adversely
affect the prices at which they can be sold and can result in high transaction
costs. If market quotations are not available, these lower-rated debt securities
will be valued in accordance with standards set by the Board of Trustees,
including the use of outside pricing services. Judgment plays a greater role in
valuing lower-rated debt securities than securities for which more extensive
quotations and last-sale information are available. Adverse publicity and
changing investor perceptions may affect the ability of outside pricing services
used by the Portfolio to value its portfolio securities, and the Portfolio's
ability to dispose of the lower-rated bonds. The market prices of lower-rated
debt securities may decline significantly in periods of general economic
difficulty, which may follow periods of rising interest rates. During an
economic downturn or a prolonged period of rising interest rates, the ability of
issuers of lower-rated debt to service their payment obligations, meet projected
goals, or obtain additional financing may be impaired. The Portfolio may choose,
at its own expense or in conjunction with others, to pursue litigation or
otherwise exercise its rights as a security holder to seek to protect the
interests of security holders if it determines this to be in the interest of
Portfolio investors.
 
     The considerations discussed above for lower-rated debt securities also are
applicable to lower quality unrated debt instruments of all types, including
loans and other direct indebtedness of businesses with poor credit standing.
Unrated debt instruments are not necessarily of lower quality than rated
securities but they may not be attractive to as many buyers.
 
     The High-Yield Bond Portfolio may also seek to achieve its investment
objective through investments in the following types of instruments.
 
   
          SHORT-TERM INSTRUMENTS.  Cash, commercial paper, short-term
     obligations, repurchase agreements, bank certificates of deposit or other
     forms of debt securities may be held to provide a reserve for future
     purchases of securities, during periods of unusual market conditions or in
     order to reduce volatility, or as a temporary defensive measure when the
     Advisers determine securities markets to be overvalued. See "Short Term
     Instruments" above under High Quality Bond Fund.
 
          REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS.  The
     High-Yield Bond Portfolio may enter into repurchase agreements and reverse
     repurchase agreements. See "Repurchase Agreements and Reverse Repurchase
     Agreements" under Money Market Fund. The Portfolio may borrow funds for
     temporary or emergency purposes, such as meeting larger than anticipated
     redemption requests, and not for leverage.

          RESTRICTED SECURITIES.  The High-Yield Bond Portfolio may not invest
     more than 15% of its net assets in securities that are subject to legal or
     contractual restrictions on resale. See "Restricted Securities" above under
     High Quality Bond Fund.
 
          OPTIONS AND FUTURES CONTRACTS.  The High-Yield Bond Portfolio may buy
     and sell options and futures contracts to manage its exposure to changing
     interest rates and securities prices. See "Options and Futures Contracts"
     above under High Quality Bond Fund.
    
 
          The Portfolio currently does not intend to engage in the writing of
     options, except under the limited circumstances described in the Statement
     of Additional Information. Nevertheless, the Portfolio has the authority to
     write options and may do so in the future if the Advisers determine that
     such transactions are in the best interests of the Portfolio.
 
   
          DELAYED DELIVERY TRANSACTIONS.  In order to help ensure the
     availability of suitable securities for the High-Yield Bond Portfolio, the
     Advisers may purchase securities for the Portfolio on a "when-issued" or on
     a "forward delivery" basis which means that the securities would be
     delivered to the Portfolio at a future date beyond customary settlement
     times. See "Delayed Delivery Transactions" above under High Quality Bond
     Fund.
 
          OTHER INVESTMENTS AND INVESTMENT TECHNIQUES.  The High-Yield Bond
     Portfolio may also utilize the following investments and investment
     techniques and practices: options on futures contracts and options on
     foreign currencies. The Portfolio does not intend to utilize any of these
     investments or techniques to the extent of more than 5% of its assets. See
     the Statement of Additional Information for further information.
 
     BALANCED FUND.  The investment objective of the Balanced Fund and the
Balanced Portfolio is to provide a high total investment return consistent with
a broad mix of stocks, bonds and money market instruments. The Balanced Fund
seeks to achieve its investment objective by investing all of its Assets in the
Balanced Portfolio.
 
     The Balanced Portfolio pursues its investment objective by investing in a
managed mix of common stocks (and/or equivalents including American Depository
Receipts), preferred stocks, debt securities of U.S. domiciled corporations,
U.S. government securities, commercial paper of U.S. corporations, and bank
obligations. The Advisers will determine the proportions of each type of
investment to achieve an asset mix they believe appropriate for an investor who
desires diversification of investment. The Balanced Portfolio will vary the
proportion of each type of asset purchased according to the Advisers'
interpretations of changes in economic conditions and the sensitivity of each
type of investment to those changes. The Advisers seek to shift emphasis among
stocks, bonds and short-term instruments to maximize participation in positive
markets and preservation of capital in negative markets and otherwise in
response to market conditions.
    
 
     The Balanced Portfolio's policy is to invest its assets in a broad list of
equity and fixed-income securities, such as common stocks, preferred stocks and
bonds, including short-term obligations. The list may be diversified not only by
companies and industries, but also by type of security. Some fixed-income
securities may also have a right to purchase common stock by means of a
conversion privilege or attached warrants. The Balanced Portfolio may vary the
percentage of assets invested in any one type of security in accordance with the
Advisers' interpretation of economic and market conditions, fiscal and monetary
policy, and underlying securities values. However, at least 25% of the total
assets of the Balanced Portfolio are always invested in fixed-income senior
securities including debt securities and preferred stock. In selecting common
stocks, emphasis is placed on investing in established companies with market
capitalizations of $100,000,000 or more and seasoned management teams. Most of
the Balanced Portfolio's non-convertible long-term debt investments consist of
"investment grade" securities (rated Baa or better by Moody's or BBB or better
by S&P), although unrated debt securities may be purchased and held if they are
judged by the Advisers to be of equivalent quality. Securities rated Baa by
Moody's or BBB by S&P may have speculative characteristics. Changes in economic
conditions or other circumstances may weaken more severely the capacity of
issuers of Baa or BBB
 
                                       18
<PAGE>   22
 
securities to make principal and interest payments than is the case for issuers
of higher grade bonds. Less than 5% of the Balanced Portfolio's investments
consist of securities rated Baa by Moody's or BBB by S&P. For a description of
these ratings, see the Appendix to the Statement of Additional Information.
 
     The Balanced Portfolio may invest a portion of its assets in short-term
U.S. Government securities with remaining maturities of one year or less and
repurchase agreements relating thereto. When the Advisers believe market
conditions warrant a temporary defensive position, the Portfolio may invest up
to 100% of its assets in these instruments or other money market instruments.
 
     EQUITY INCOME FUND.  The investment objective of the Equity Income Fund and
the Equity Income Portfolio is to provide a high level of current income through
investment in a diversified portfolio of common stocks with relatively high
current yields; capital appreciation is a secondary objective. The Equity Income
Fund seeks to achieve its investment objective by investing all of its Assets in
the Equity Income Portfolio.
 
     The Equity Income Portfolio seeks to achieve its investment objective by
investing primarily in a diversified portfolio of stocks of companies which, in
the opinion of the Advisers, are fundamentally sound financially and which pay
relatively high dividends on a consistent basis. The Advisers attempt to manage
the Portfolio so that it will outperform other equity income funds in negative
markets. As a result of this objective, the Portfolio may underperform relative
to other equity income funds in positive markets. The Portfolio invests
primarily in common stocks and preferred stocks listed on the New York Stock
Exchange and on other national securities exchanges and, to a lesser extent, in
stocks that are traded over-the-counter. The Portfolio also invests in bonds and
short-term obligations as well as securities convertible into common stocks,
preferred stocks, debt securities and short-term obligations. The Portfolio
allocates its investments among different industries and companies, and changes
its portfolio securities for investment considerations and not for trading
purposes.
 
   
     The Equity Income Portfolio's policy is to invest in a broad list of equity
and fixed-income securities, including short-term obligations. The list may be
diversified not only by companies and industries, but also by type of security.
Some fixed-income securities may also have a call on common stock by means of a
conversion privilege or attached warrants. The Portfolio may vary the percentage
of assets invested in any one type of security in accordance with the Advisers'
interpretation of economic and market conditions, fiscal and monetary policy,
and underlying security values.
    
 
   
     EQUITY VALUE FUND.  The investment objective of the Equity Value Fund and
the Equity Value Portfolio is to provide a high total investment return through
investment in a diversified portfolio of common stocks. The Equity Value Fund
seeks to achieve its investment objective by investing all of its Assets in the
Equity Value Portfolio.
    
 
   
     The Equity Value Portfolio seeks to achieve its investment objective by
investing primarily in a diversified portfolio of stocks of companies which, in
the opinion of the Advisers, are trading at low valuations relative to market
and/or historical levels. These stocks tend to have relatively low
price/earnings ratios and/or relatively low price/book value ratios. Low
price/earnings ratios or price/book value ratios means that the stock is less
expensive than average relative to the company's earnings or book value,
respectively. The Portfolio invests primarily in common stocks listed on the New
York Stock Exchange and on other national securities exchanges and, to a lesser
extent, in stocks that are traded over-the-counter. The Portfolio may also
invest in bonds and short-term obligations as well as securities convertible
into common stocks, preferred stocks, debt securities and short-term
obligations. The Portfolio allocates its investments among different industries
and companies, and changes its portfolio securities for investment
considerations and not for trading purposes.
    
 
     The Equity Value Portfolio's policy is to invest in a broad list of equity
and fixed-income securities, including short-term obligations. The list may be
diversified not only by companies and industries, but also by type of security.
Some fixed-income securities may also have a call on common stock by means of a
conversion privilege or attached warrants. The Portfolio may vary the percentage
of assets invested
 
                                       19
<PAGE>   23
 
in any one type of security in accordance with the Advisers' interpretation of
economic and market conditions, fiscal and monetary policy, and underlying
security values.
 
     GROWTH & INCOME FUND.  The investment objective of the Growth & Income Fund
and the Growth & Income Portfolio is to provide current income and capital
appreciation. The Growth & Income Fund seeks to achieve its investment objective
by investing all of its Assets in the Growth & Income Portfolio.
 
     The Growth & Income Portfolio seeks to achieve its investment objective by
investing primarily in a diversified portfolio of securities selected for their
potential to generate current income or long term capital appreciation. In
general, the objective of the Portfolio is to achieve greater potential for
capital appreciation than an income fund and less price volatility than a growth
fund. The Growth & Income Portfolio invests primarily in common stocks and
preferred stocks listed on the New York Stock Exchange and on other national
securities exchanges and, to a lesser extent, in stocks that are traded
over-the-counter. The Portfolio also invests in bonds and short-term obligations
as well as securities convertible into common stocks, preferred stocks, debt
securities and short-term obligations. The Portfolio allocates its investments
among different industries and companies and changes its portfolio securities
for investment considerations and not for trading purposes. In general, the
Portfolio seeks to invest in growing, financially stable and undervalued
companies.
 
   
     The Growth & Income Portfolio's policy is to invest in a broad list of
equity and fixed income securities, including short-term obligations. The list
may be diversified not only by companies and industries, but also by type of
security. Some fixed income securities may also have a call on common stock by
means of a conversion privilege or attached warrants. The Portfolio may vary the
percentage of assets invested in any one type of security in accordance with the
Advisers' interpretation of economic and market conditions, fiscal and monetary
policy, and underlying securities values.
    
 
     EQUITY GROWTH FUND.  The investment objective of the Equity Growth Fund and
the Equity Growth Portfolio is to provide a high level of capital appreciation
through investment in a diversified portfolio of common stocks with potential
for above average growth in earnings and dividends; current income is a
secondary objective. The Equity Growth Fund seeks to achieve its investment
objective by investing all of its Assets in the Equity Growth Portfolio.
 
     The Equity Growth Portfolio seeks to achieve its investment objective by
investing primarily in a diversified portfolio of common stocks, but may also
invest in other types of securities such as preferred stocks, convertible and
non-convertible bonds, warrants and foreign securities including American
Depository Receipts ("ADRs"). Under normal circumstances, at least 65% of the
assets of the Portfolio are invested in equity securities. This is a fundamental
investment policy and may not be changed without investor approval. The Equity
Growth Portfolio invests primarily in stocks of companies that have a market
value of all their issued and outstanding common stock of $10 to $15 billion and
preferred stocks listed on the New York Stock Exchange and on other national
securities exchanges and, to a lesser extent, in stocks that are traded
over-the-counter. The Portfolio also invests in bonds and short-term obligations
as well as securities convertible into common stocks, preferred stocks, debt
securities and short-term obligations. The Portfolio allocates its investments
among different industries and companies, and changes its portfolio securities
for investment considerations and not for trading purposes.
 
   
     The Equity Growth Portfolio's policy is to invest in a broad list of equity
and fixed-income securities, including short-term obligations. The list may be
diversified not only by companies and industries, but also by type of security.
Some fixed-income securities may also have a call on common stock by means of a
conversion privilege or attached warrants. The Portfolio may vary the percentage
of assets invested in any one type of security in accordance with the Adviser's
interpretation of economic and market conditions, fiscal and monetary policy,
and underlying security values.
    
 
     SPECIAL EQUITY FUND.  The investment objective of the Special Equity Fund
and the Special Equity Portfolio is to provide a high level of capital
appreciation through investment in a diversified
 
                                       20
<PAGE>   24
 
portfolio of common stocks of small to medium size companies. The Special Equity
Fund is designed for investors in search of substantial long-term growth who can
accept above-average stock market risk and little or no current income. The
Special Equity Fund seeks to achieve its investment objective by investing all
of its Assets in the Special Equity Portfolio.
 
     The Special Equity Portfolio seeks to achieve its investment objective by
investing primarily in a diversified portfolio of stocks of small to medium size
companies which, in the opinion of the Advisers, will present an opportunity for
significant increases in earnings and/or value, without consideration for
current income. The Portfolio's primary equity investments will be common stocks
of small and medium sized U.S. companies with market capitalizations of less
than $2 billion. Multiple managers are used to control the volatility often
associated with investments in small to medium size companies and to maximize
opportunities in positive markets. The Portfolio may also invest in bonds and
short-term obligations as well as securities convertible into common stocks,
preferred stocks, debt securities and short-term obligations. The Special Equity
Portfolio allocates its investments among different industries and companies,
and changes its portfolio securities for investment considerations and not for
trading purposes.
 
   
     While the Special Equity Portfolio's policy is to invest its assets
primarily in common stocks with potential for above average growth in earnings,
appreciation may be sought in other types of securities such as preferred
stocks, convertible and non-convertible bonds, warrants and foreign securities
including American Depository Receipts. The Special Equity Portfolio may vary
the percentage of assets invested in any one type of security in accordance with
the Advisers' interpretation of economic and market conditions, fiscal and
monetary policy, and underlying securities values. In selecting stocks, emphasis
is placed on investing in companies with small to medium market capitalizations,
i.e., the market value of all issued and outstanding common stock of the company
will be less than $2 billion. Investing in equity securities of small to medium
companies involves risks not typically associated with investment in comparable
securities of large companies. Such smaller and medium companies may have narrow
product lines and limited financial and managerial resources. Since the market
for the equity securities of small and medium companies is often characterized
by less information and liquidity than that for the equity securities of large
companies, securities of such small and medium companies may be subject to more
abrupt or erratic market movements than securities of large companies or market
averages in general. Therefore, an investment in the Special Equity Fund may be
subject to greater declines in value than an investment in an equity fund
investing in the equity securities of large companies.
    
 
   
     AGGRESSIVE EQUITY FUND.  The investment objective of the Aggressive Equity
Fund and the Aggressive Equity Portfolio is to provide a high level of capital
appreciation through investment in a diversified portfolio of common stocks of
small to medium size companies. The Aggressive Equity Fund is designed for
investors in search of substantial long-term growth who can accept above-average
stock market risk and little or no current income. The Aggressive Equity Fund
seeks to achieve its investment objective by investing all of its Assets in the
Aggressive Equity Portfolio.
    
 
   
     The Aggressive Equity Portfolio seeks to achieve its investment objective
by investing primarily in a diversified portfolio of stocks of small to medium
size companies which, in the opinion of the Advisers, will present an
opportunity for significant increases in earnings, revenue and/or value, without
consideration for current income. The Portfolio's primary equity investments are
common stocks of small and medium sized U.S. companies with market
capitalizations between $750 million and $2.5 billion. The Portfolio may also
invest in bonds and short-term obligations as well as securities convertible
into common stocks, preferred stocks, debt securities and short-term
obligations. The Aggressive Equity Portfolio allocates its investments among
different industries and companies, and changes its portfolio securities for
investment considerations and not for trading purposes.
    
 
     While the Aggressive Equity Portfolio's policy is to invest its assets
primarily in common stocks with potential for above average growth in earnings
and/or revenue, appreciation may be sought in other types of securities such as
preferred stocks, convertible and non-convertible bonds, warrants and
 
                                       21
<PAGE>   25
 
foreign securities including American Depository Receipts. The Aggressive Equity
Portfolio may vary the percentage of assets invested in any one type of security
in accordance with the Advisers' interpretation of economic and market
conditions, fiscal and monetary policy, and underlying securities values.
 
     In selecting stocks, emphasis is placed on investing in companies with
consistent, above-average and accelerating profitability and growth. These
companies tend to have higher price/earnings ratios which means that the stock
is more expensive than average relative to the company's earnings. Investing in
equity securities of small to medium companies involves risks not typically
associated with investment in comparable securities of large companies. Such
smaller and medium companies may have narrow product lines and limited financial
and managerial resources. Since the market for the equity securities of small
and medium companies is often characterized by less information and liquidity
than that for the equity securities of large companies, securities of such small
and medium companies may be subject to more abrupt or erratic market movements
than securities of large companies or market averages in general. Therefore, an
investment in the Aggressive Equity Fund may be subject to greater declines in
value than an investment in an equity fund investing in the equity securities of
large companies.
 
   
     INTERNATIONAL EQUITY FUND.  The investment objective of the International
Equity Fund is to provide a high level of long-term capital appreciation through
investment in a diversified portfolio of securities of foreign issuers. The
International Equity Fund seeks to achieve its investment objective by investing
all of its Assets in the International Equity Portfolio.
 
     The International Equity Portfolio seeks to achieve its investment
objective by investing primarily in foreign securities. Foreign securities are
defined as securities of issuers, wherever organized, which trade solely on a
foreign exchange or over-the-counter market, or, in the judgment of the
Advisers, have their principal activities outside of the United States. In
determining whether an issuer's principal activities and interests are outside
the United States, the Advisers will look at such factors as the location of its
assets, operations, facilities, personnel, sales and earnings. Under normal
circumstances, at least 65% of the assets of the Portfolio are invested in
foreign equity securities. The Advisers will purchase securities of companies in
a minimum of 3 countries outside the United States.
    
 
     The Advisers use an approach to investing looking to identify fundamental
values in stocks its selects; further, when allocating the Portfolio's
investments among geographic regions and individual countries, the Advisers
consider various criteria, such as prospects for relative economic growth among
countries, expected levels of inflation, government policies influencing
business conditions, and the outlook for currency relationships. The Portfolio
expects to invest most of its assets in securities of issuers located in
developed countries in these geographic areas: Canada, the Far East, Australia
and Europe.
 
   
     The International Equity Portfolio may invest up to 10% of its assets in
securities of issuers in the world's emerging markets. Countries with emerging
markets include those that have an emerging stock market as defined by the
International Finance Corporation, those with low- to middle-income economies
according to the World Bank, and those listed in World Bank publications as
developing. While the Advisers believe that these investments present the
possibility for significant growth over the long-term, they also entail
significant risks. Many investments in emerging markets can be considered
speculative, and their prices can be much more volatile than those in the more
developed nations of the world. This difference reflects the greater
uncertainties of investing in less established markets and economies.
    
 
     The International Equity Portfolio may invest in all types of securities,
most of which are denominated in foreign currencies. While the Advisers expect
that opportunities for long term capital appreciation will come primarily from
common stocks, securities convertible into common stock, non-convertible
preferred stocks and depository receipts for these securities, the Portfolio may
also invest in any type or quality of debt securities if the Advisers believe
that doing so may result in long term growth. In addition, the Portfolio may
invest in high-yielding, lower rated debt securities. See the
 
                                       22
<PAGE>   26
 
discussion of lower rated debt securities under "High-Yield Bond Fund" above.
Forward foreign currency exchange contracts may also be entered into for the
purchase or sale of foreign currency solely for hedging purposes against adverse
rate changes on both a long and short term basis. A currency exchange contract
allows a definite price in dollars to be fixed for foreign securities that have
been purchased or sold (but not settled) for the Portfolio. Entering into such
exchange contracts may result in the loss of all or a portion of the benefits
which otherwise could have been obtained from favorable movements in exchange
rates. In addition, entering into such contracts means incurring certain
transaction costs and bearing the risk of incurring losses if rates do not move
in the direction anticipated.
 
     Investments in foreign equity and debt securities involve increased or
additional risks from those encountered when investing in securities of domestic
issuers. The Advisers evaluate the risks and opportunities when investing in
particular foreign securities. Such risks include (1) currency fluctuations; (2)
restrictions on, and costs associated with, the exchange of currencies; (3) the
difficulty in obtaining or enforcing a court judgment abroad; (4) reduced levels
of publicly available information concerning issuers; (5) restrictions on
foreign investment in other jurisdictions; (6) reduced levels of governmental
regulation of foreign securities markets; (7) difficulties in effecting the
repatriation of capital invested abroad; (8) difficulties in transaction
settlements and the effect of this delay on shareholder equity; (9) foreign
withholding taxes; (10) political, economic, and similar risks, including
expropriation and nationalization; (11) different accounting, auditing, and
financial standards; (12) price volatility; and (13) the diverse structure and
liquidity of various countries and regions.
 
                 CERTAIN INVESTMENT TECHNIQUES AND RESTRICTIONS
 
   
     Balanced Fund, Equity Income Fund, Equity Value Fund, Growth & Income Fund,
Equity Growth Fund, Special Equity Fund, Aggressive Equity Fund and
International Equity Fund. Following is a description of certain investment
techniques employed by the Balanced Portfolio, Equity Income Portfolio, Equity
Value Portfolio, Growth & Income Portfolio, Equity Growth Portfolio, Special
Equity Portfolio, Aggressive Equity Portfolio and International Equity Portfolio
and certain types of securities invested in by those Portfolios and associated
risks For information relating to certain of these techniques and restrictions
and how they relate to the Money Market Fund, High Quality Bond Fund,
Intermediate Government Bond Fund and Government/Corporate Bond Fund, see
"Investment Objectives and Policies of the Funds" above.
    
 
     OPTIONS AND FUTURES CONTRACTS.  Each Portfolio may enter into transactions
in futures contracts, options on futures contracts, options on securities
indexes and options on securities, for the purpose of hedging each Portfolio's
securities, which would have the effect of reducing the volatility of its net
asset value. In general, each such transaction involves the establishment of a
position which is expected to move in a direction opposite to that of the
security or securities being hedged.
 
     For example, each Portfolio may sell futures contracts, or purchase put
options on futures contracts, securities indexes or securities for the purpose
of protecting against an anticipated decline in the value of securities held by
that Portfolio. In the event that such decline occurs, and the hedging
transaction is successful, the reduced value of portfolio securities will be
offset, in whole or in part, by a corresponding gain on the futures or option
position. Conversely, when the Portfolio is not fully invested in the securities
market, and it expects a significant market advance, it may purchase futures
contracts or call options on futures contracts, securities indexes or securities
in order to gain rapid market exposure that may in part or entirely offset
increases in the cost of securities that that Portfolio intends to purchase.
 
     The Statement of Additional Information includes further information about
the transactions in futures and option contracts that may be entered into by
each Portfolio.
 
     Gain or loss to each Portfolio on transactions in security index futures or
options will depend on price movements in the stock market generally (or in a
particular industry or segment of the market),
 
                                       23
<PAGE>   27
 
rather than price movements of individual securities. A securities index assigns
relative values to the securities included in the index and the index fluctuates
with changes in the market values of the securities so included. Some securities
index futures or options are based on broad market indexes, such as the Standard
& Poor's 500 or the New York Stock Exchange Composite Index. In contrast,
certain exchanges offer futures or options on narrower market indexes, such as
the Standard & Poor's 100 or indexes based on an industry or market segment,
such as oil and gas stocks. Options on indexes and options on securities are
traded on securities exchanges regulated by the SEC. Futures contracts and
options on futures contracts are traded only on designated contract markets
regulated by the Commodity Futures Trading Commission and through a registered
futures commission merchant which is a member of such contract market. A
commission must be paid on each completed purchase and sale transaction.
Transactions on such exchanges are cleared through a clearing corporation, which
guarantees performance between the clearing members which are parties to each
contract.
 
     Each Portfolio currently does not intend to engage in the writing of
options, except for the purpose of terminating an existing position or under the
limited circumstances described in the Statement of Additional Information.
Nevertheless, each Portfolio has the authority to write options and may do so in
the future if the Advisers determine that such transactions are in the best
interests of the Fund.
 
   
     SHORT-TERM INSTRUMENTS.  Each of the Balanced Portfolio, Equity Income
Portfolio, Equity Value Portfolio, Growth & Income Portfolio, Equity Growth
Portfolio, Special Equity Portfolio, Aggressive Equity Portfolio and
International Equity Portfolio may invest in cash, commercial paper, short-term
obligations, repurchase agreements or other forms of debt securities (including,
without limitation, a short-term investment fund investing in any of such
securities). See "Short-Term Instruments" above under High Quality Bond Fund.
    
 
   
     REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS.  Each of the
Balanced Portfolio, Equity Income Portfolio, Equity Value Portfolio, Growth &
Income Portfolio, Equity Growth Portfolio, Special Equity Portfolio, Aggressive
Equity Portfolio and International Equity Portfolio may enter into repurchase
agreements and reverse repurchase agreements and may borrow funds for temporary
or emergency purposes, such as meeting larger than anticipated redemption
requests, and not for leverage. See "Repurchase Agreements and Reverse
Repurchase Agreements" above under Money Market Fund.
    
 
   
     RESTRICTED SECURITIES.  Each of the Balanced Portfolio, Equity Income
Portfolio, Equity Value Portfolio, Growth & Income Portfolio, Equity Growth
Portfolio, Special Equity Portfolio, Aggressive Equity Portfolio and
International Equity Portfolio may not invest more than 15% of its net assets in
securities that are subject to legal or contractual restrictions on resale. See
"Restricted Securities" above under High Quality Bond Fund.
    
 
   
     DELAYED DELIVERY TRANSACTIONS.  In order to help insure the availability of
suitable securities for each of the Balanced Portfolio, Equity Income Portfolio,
Equity Value Portfolio, Growth & Income Portfolio, Equity Growth Portfolio,
Special Equity Portfolio, Aggressive Equity Portfolio and International Equity
Portfolio, the Advisers may purchase securities for each such Portfolio on a
"when-issued" or on a "forward delivery" basis. See "Delayed Delivery
Transactions" above under High Quality Bond Fund.
    
 
     Changes to the securities of each Portfolio are generally made without
regard to the length of time a security has been held, or whether a sale would
result in the recognition of a profit or loss. Therefore, the rate of portfolio
turnover is not a limiting factor to trading when such trading is deemed
appropriate. Each Portfolio engages in trading if it believes a transaction net
of costs (including custodian charges) will help it achieve its investment
objective. The portfolio turnover rate for each Portfolio in 1995 is set forth
above under "Condensed Financial Information". The amount of brokerage
commissions and realized capital gains will tend to increase as the level of
portfolio activity increases. The primary consideration in placing portfolio
security transactions with broker-dealers for execution is to obtain, and
maintain the availability of, execution at the most favorable prices and in the
most
 
                                       24
<PAGE>   28
 
effective manner possible. See "Portfolio Transactions and Brokerage
Commissions" in the Statement of Additional Information.
 
   
     Balanced Fund, Equity Income Fund, Equity Value Fund, Growth & Income Fund,
Equity Growth Fund, Special Equity Fund and Aggressive Equity Fund.  Each such
Portfolio's current policy is not to invest more than 25% of its assets in
securities of foreign issuers, including investments in sponsored American
Depository Receipts ("ADRs"). ADRs are receipts typically issued by an American
Bank or trust company evidencing ownership of the underlying foreign securities.
The Advisers do not intend to concentrate more than 25% of such foreign
investments in any one type of instrument or in any foreign country. Each
Portfolio's investments in unlisted foreign securities, not including ADRs, are
subject to the overall restrictions applicable to investments in illiquid
securities. Foreign securities, including ADRs, may represent a greater degree
of risk than do securities of domestic issuers due to possible exchange rate
fluctuations, possible exchange controls, less publicly available information,
more volatile markets, less securities regulation, less favorable tax provisions
(including possible withholding taxes), changes in governmental administration
or economic or monetary policy (in the United States or abroad), war or
expropriation. Each Portfolio may invest up to 5% of its assets in closed-end
investment companies which primarily hold foreign securities. Forward foreign
currency exchange contracts may also be entered into for the purchase or sale of
foreign currency solely for hedging purposes against adverse rate changes. A
currency exchange contract allows a definite price in dollars to be fixed for
foreign securities that have been purchased or sold (but not settled) for each
Portfolio. Entering into such exchange contracts may result in the loss of all
or a portion of the benefits which otherwise could have been obtained from
favorable movements in exchange rates. In addition, entering into such contracts
means incurring certain transaction costs and bearing the risk of incurring
losses if rates do not move in the direction anticipated.
    
 
     All Funds.  As "diversified" funds, no more than 5% of the assets of any
Portfolio may be invested in the securities of one issuer (other than U.S.
Government securities), except that up to 25% of each Portfolio's assets may be
invested without regard to this limitation. No Portfolio will invest more than
25% of its assets in the securities of issuers in any one industry. These are
fundamental investment policies which may not be changed without investor
approval. As a non-fundamental operating policy, no more than 15% (10% in the
case of the Money Market Portfolio) of the net assets of any Portfolio may be
invested in (i) securities the resale of which are subject to legal or
contractual restrictions is restricted under federal securities laws and (ii)
illiquid or not readily marketable securities (including repurchase agreements
maturing in more than seven days). Additional fundamental investment and
operating policies of the Portfolios are contained in the Statement of
Additional Information.
 
     LENDING OF PORTFOLIO SECURITIES.  The Portfolios may lend their portfolio
securities to brokers, dealers and other financial organizations. By lending its
securities, a Portfolio can increase its income by continuing to receive
interest on the loaned securities as well as by either investing the cash
collateral in short-term securities or obtaining yield in the form of interest
paid when U.S. Government obligations are used as collateral. There may be risks
of delay in receiving additional collateral or risks of delay in recovery of the
securities or even loss of rights in the collateral should the borrower of the
securities fail financially. A Portfolio will adhere to the following conditions
whenever its securities are loaned: (i) the Portfolio must receive at least 100%
cash collateral or equivalent securities from the borrower; (ii) the borrower
must increase this collateral whenever the market value of the loaned securities
including accrued interest exceeds the level of the collateral; (iii) the
Portfolio must be able to terminate the loan at any time; (iv) the Portfolio
must receive reasonable interest on the loan, as well as any dividends, interest
or other distributions on the loaned securities, and any increase in market
value; (v) the Portfolio may pay only reasonable custodian fees in connection
with the loan; and (vi) voting rights on the loaned securities may pass to the
borrower. However, if a material event adversely affecting the loaned securities
were to occur, the Portfolio would terminate the loan and regain the right to
vote the securities.
 
                                       25
<PAGE>   29
 
                            HUB & SPOKE(R) STRUCTURE
 
   
     The Trust and the Portfolio Series have licensed certain proprietary
rights, know-how and financial services referred to as Hub and Spoke(R) from
Signature Financial Group, Inc. ("Signature"). The Trust invests in the
Portfolio Series through Signature's Hub and Spoke(R) mutual fund method. Hub
and Spoke(R) employs a two-tier, master/feeder fund structure. Hub and Spoke(R)
is a registered service mark of Signature.
    
 
     In addition to selling beneficial interests to the Trust, the Portfolio
Series may sell beneficial interests of its Portfolios to other mutual funds,
insurance company separate accounts, collective investment vehicles or
institutional investors. Such investors will invest in the Portfolios on the
same terms and conditions as the Funds and will pay a proportionate share of the
Portfolios' expenses. However, the other investors investing in such Portfolios
are not required to sell their shares at the same public offering price as the
Funds due to variations in sales commissions and other operating expenses.
Therefore, all investors should be aware that these differences may result in
differences in returns experienced by investors in the different entities that
invest in each Portfolio. Information concerning other holders of interests in
the Portfolios is available from Diversified at (914) 697-8000.
 
     The investment objective of a Fund may be changed without the approval of
the Fund's shareholders, but not without written notice thereof to shareholders
thirty days prior to implementing the change. If there were a change in a Fund's
investment objective, shareholders should consider whether that Fund remains an
appropriate investment in light of their then-current financial positions and
needs. The investment objective of a Portfolio may also be changed without the
approval of the investors in that Portfolio, but not without written notice
thereof to the investors in that Portfolio (and notice by the Trust to
shareholders of the Fund invested in that Portfolio) thirty days prior to
implementing the change. There can, of course, be no assurance that the
investment objective of either a Fund or a Portfolio will be achieved. See
"Investment Restrictions" herein and in the Statement of Additional Information
for a description of the fundamental policies of the Funds and the Portfolios
that cannot be changed without approval by the holders of a "majority of the
outstanding voting securities" (as defined in the 1940 Act) of the Funds or
Portfolios, respectively. Except as stated otherwise, all investment guidelines,
policies and restrictions described herein and in the Statement of Additional
Information are nonfundamental.
 
     Smaller entities investing in a Portfolio may be materially affected by the
actions of larger entities investing in that Portfolio. For example, if a large
fund withdraws from a Portfolio, the remaining investors may experience higher
pro rata operating expenses, thereby producing lower returns. Additionally, the
affected Portfolio may become less diverse, resulting in increased portfolio
risk. (However, this possibility also exists for any type of collective
investment vehicle which has institutional or other large investors.) Also,
investors with a greater pro rata ownership in a Portfolio could have effective
voting control of the operations of that Portfolio. Whenever the Trust is
requested to vote on matters pertaining to a Portfolio (other than a vote to
continue a Portfolio upon the withdrawal of an investor in the Portfolio), the
Trust will hold a meeting of shareholders of the affected Funds and will cast
all of its votes in the same proportion as the votes of the Fund's shareholders.
Fund shareholders who do not vote will not affect the Trust's votes at the
Portfolio meeting. The percentage of the Trust's votes representing Fund
shareholders not voting will be voted by the Trustees of the Trust in the same
proportion as the Fund shareholders who do, in fact, vote. Certain changes in
the investment objectives, policies or restrictions of a Portfolio may require
that the Trust withdraw a Fund's interest in that Portfolio. Any such withdrawal
could result in a distribution "in kind" of portfolio securities (as opposed to
a cash distribution from the series). If securities are distributed, a Fund
could incur brokerage or other charges in converting the securities to cash. In
addition, the distribution in kind may result in a less diversified portfolio of
investments or adversely affect the liquidity of a Fund. Notwithstanding the
above, there are other means for meeting shareholders redemption requests such
as temporary borrowings.
 
                                       26
<PAGE>   30
 
     The Trust may withdraw the investment of a Fund from its corresponding
Portfolio at any time, if the Board of Trustees of the Trust determines that it
is in the best interests of the Fund to do so. Upon any such withdrawal, the
Board of Trustees of the Trust would consider what action might be taken,
including the investment of all the Assets of a Fund in another pooled
investment entity having the same investment objective as the Fund or the
retention of an investment adviser to manage the Fund's assets in accordance
with the investment policies described herein. In the event the event the
Trustees of the Trust were unable to find a substitute investment company in
which to invest the Fund's assets and were unable to secure directly the
services of an investment adviser and investment manager, the Trustees would
determine the best course of action.
 
                  MANAGEMENT OF THE TRUST AND PORTFOLIO SERIES
 
     The Trust has not retained the services of an investment adviser since the
Trust seeks to achieve the investment objective of each Fund by investing all of
the Assets of each Fund in a corresponding Portfolio. The respective Boards of
Trustees of the Trust and of the Portfolio Series provide broad supervision over
the affairs of the Trust and of the Portfolio Series, respectively. The Trustees
of the Trust who are not "interested persons" of the Trust are separate from and
independent from the Trustees of the Portfolio Series who are not "interested
persons" of the Portfolio Series. For further information about the Trustees and
officers of the Trust and the Portfolio Series see "Management of the Trust and
Portfolio Series" in the Statement of Additional Information. A majority of each
of the Trust's and the Portfolio Series' Trustees are not affiliated with the
Advisers.
 
INVESTMENT ADVISORY SERVICES
 
     Subject to such policies as the Board of Trustees of the Portfolio Series
may determine and pursuant to Investment Advisory Agreements (the "Advisory
Agreements") with the Portfolio Series with respect to each Portfolio,
Diversified manages the assets of each Portfolio in accordance with the
investment policies approved by the Board of Trustees. Subject to such policies,
Diversified provides general investment advice to each Portfolio. For its
services under the Advisory Agreements, Diversified receives from each Portfolio
fees accrued daily and paid monthly at an annual rate equal to the percentages
specified in the table below of the average daily net assets. Diversified is
currently waiving a portion of its investment advisory fee. Investment
management decisions are taken by a committee of Diversified's personnel and not
by a particular individual.
 
   
     Management's discussion of the Funds' performance for the fiscal year ended
December 31, 1995 is included in the Funds' Annual Report to Shareholders,
copies of which may be obtained free of charge from the Funds' Distributor.
    
 
     For each Portfolio, Diversified has entered into an Investment Subadvisory
Agreement (each a "Subadvisory Agreement") with the Subadvisers listed in the
table below (each a "Subadviser", and collectively the "Subadvisers"). For its
services under each Subadvisory Agreement, the Subadvisers receive a fee from
Diversified at an annual rate equal to the percentages specified in the table
below of the corresponding Portfolio's average net assets. Each fee will be
accrued monthly by multiplying the arithmetic average of the beginning and
ending monthly net assets in the Portfolio by the fee schedule and dividing by
12. Each fee will be paid on a quarterly basis.

Diversified and the Board of Trustees of the Portfolio Series. Each Subadviser
furnishes at its own expense all services, facilities and personnel necessary in

DISTRIBUTION PLAN AND AGREEMENT
 
   
     The Trustees of the Trust have adopted a Distribution Plan in accordance
with Rule 12b-1 under the 1940 Act after having concluded that there is a
reasonable likelihood that the Distribution Plan will benefit the Funds and
their shareholders. As contemplated by the Distribution Plan, the Distributor
acts as the agent of the Funds in connection with the offering of shares of the
Funds pursuant to a Distribution Agreement.
    
 
     Under the Distribution Plan, the Distributor may receive a fee from each
Fund at an annual rate not to exceed 0.25% of the Fund's average daily net
assets in anticipation of, or as reimbursement for, expenses incurred in
connection with the sale of shares of the Fund, such as (i) payments of
quarterly trail or maintenance commissions to registered representatives of the
Distributor or other broker-dealers in an amount not to exceed on an annual
basis 0.25% of the average daily net assets maintained in the Fund by their
customers, (ii) reimbursements of sales commissions advanced by the Distributor
to sales brokers, and (iii) advertising expenses and the expenses of printing
(excluding typesetting) and distributing prospectuses and reports used for sales
purposes, expenses of preparing and printing sales literature and other
distribution-related expenses. The Distributor provides to the Trustees of the
Trust a quarterly written report of amounts expended by it and the purposes for
which such expenditures were made.
 
ADMINISTRATOR
 
   
     Pursuant to an Administrative and Transfer Agency Services Agreement with
the Trust and under the Advisory Agreement with the Portfolio Series,
Diversified, as Administrator, provides the Trust and the Portfolio Series with
general office facilities and supervises the overall administration of the Trust
and the Portfolio Series, including, among other responsibilities, the
negotiation of contracts and fees with, and the monitoring of performance and
billings of, the independent contractors and agents of the Trust or the
Portfolio Series; the preparation and filing of all documents required for
compliance by the Trust or the Portfolio Series with applicable laws and
regulations; providing equipment and clerical personnel necessary for
maintaining the organization of the Trust or the Portfolio Series; preparation
of certain documents in connection with meetings of Trustees and shareholders of
the Trust and investors in the Portfolio Series; and the maintenance of books
and records of the Trust and the Portfolio Series. Diversified provides persons
satisfactory to the Board of Trustees of each of the Trust and the Portfolio
Series to serve as officers of the Trust or the Portfolio Series, as the case
may be. Such officers, as well as certain other employees and Trustees of the
Trust or the Portfolio Series, may be directors, officers or employees of
Diversified or its affiliates. In addition, Diversified provides transfer agency
services to the Trust. For providing these services and facilities and for
bearing the related expenses, Diversified, as Administrator, receives a fee from
each Fund accrued daily and paid monthly at an annual rate equal to 0.30% of the
average daily net assets of the Fund. The Administrator is currently waiving a
portion of its administrative services fee. Diversified acts as Administrator to
the Portfolios pursuant to the Advisory Agreement and receives no additional
compensation for providing such administrative services.
    
 
SERVICE AGENTS
 
     All shareholders must be represented by Diversified or another Service
Agent that has entered into a Service Agreement with Diversified. Diversified
acts as a Service Agent pursuant to its Administrative Services Agreement with
the Trust and receives no additional compensation from the Funds for such
shareholder services. The service fees of any other Service Agents will be paid
by Diversified from its administrative services fees. The services provided by a
Service Agent may include establishing and maintaining shareholder accounts,
processing purchase and redemption transactions, arranging for bank wires,
answering client inquiries regarding the Trust, assisting clients in changing
account designations and addresses, providing periodic statements showing the
client's account balance,
 
                                       31
<PAGE>   35
 
transmitting proxy statements, periodic reports, updated Prospectuses and other
communications to shareholders and, with respect to meetings of shareholders,
collecting, tabulating and forwarding to the Trust executed proxies and
obtaining such other information and performing such other services as
Diversified or the Service Agent's clients may reasonably request and agree upon
with the Service Agent. Service Agents may separately charge their clients
additional fees only to cover provision of additional or more comprehensive
services not already provided under the Administrative Services Agreement with
Diversified, or of the type or scope not generally offered by a mutual fund,
such as enhanced retirement or trust reporting. Any Service Agent must agree to
transmit to shareholders who are its customers appropriate disclosures of any
fees that it may charge them directly.
 
                      PURCHASES AND REDEMPTIONS OF SHARES
 
PURCHASES
 
     The Trust is designed to meet the long-term investment needs of, and will
be available only as a funding vehicle to, Qualified Investors (as defined on
the cover page of this Prospectus). The retirement plans which may invest in the
Funds are hereinafter referred to as "Plans" and the employees, self-employed
persons or individuals participating in such Plans are hereinafter referred to
as "Plan Participants". With respect to these Plans, the employer and/or the
Plan Participants will make contributions which may be invested in shares of the
Funds pursuant to the terms and conditions of the underlying Plan.
 
     Shares of the Funds may be purchased without a sales charge on any day on
which the Adviser and applicable Subadviser or Subadvisers are open for business
("Fund Business Day") at the net asset value next determined after an order in
proper form is transmitted to and accepted by the Distributor. The procedure
through which a Qualified Investor or Plan Participant may transmit an order to
the Distributor will be set forth in the documents relating to the underlying
Plan. Plan Participants should contact their Plan administrator, if appropriate,
for further information on how to purchase shares of the Funds. In addition,
Qualified Investors and Plan Participants may call the Distributor at
914-697-8000 for information with respect to the proper procedure to transmit an
order; however, except for purchase orders in connection with exchanges from
other funds as described below under "Exchange Privileges", purchases may not be
effected through telephone orders. The minimum initial investment is $5,000 (the
Trust is currently waiving its minimum initial investment requirement) and there
is no minimum for subsequent investments. However, a particular Plan may impose
different minimum initial and minimum subsequent investment requirements.
Purchases will be effected on the same day the purchase order is received by the
Distributor provided such order is received prior to 4:00 p.m. New York time on
any day on which the New York Stock Exchange ("NYSE") is open for trading.
Shares earn dividends from and including the day the purchase is effected, but
not on the day of redemption.
 
   
     Checks received from a Qualified Investor are invested in full and
fractional shares. If shares are purchased with a check that does not clear, the
purchase will be cancelled and any losses or fees incurred in the transaction
will be the responsibility of such Qualified Investor. Checks must be drawn on
or payable through a U.S. bank and be in U.S. dollars. If shares are purchased
by check and a redemption request relating to such shares is received within 15
days of a purchase, the Trust will release such redemption proceeds when the
check clears. It is possible, although unlikely, that this could take up to 15
days.
    
 
     Underlying Plans which include fixed investment options issued by insurance
companies may restrict or prohibit the purchase of shares of certain of the
Funds with monies withdrawn from any such fixed interest investment option.
 
     Each Fund reserves the right to cease offering its shares for sale at any
time or to reject any order for the purchase of its shares.
 
                                       32
<PAGE>   36
 
REDEMPTIONS
 
     A Qualified Investor or Plan Participant may redeem all or any portion of
the shares in its account at any time at the net asset value next determined
after a redemption request in proper form is received and accepted by the
Distributor. The proper form for a redemption request may vary in accordance
with the terms of the underlying Plan through which a Qualified Investor or Plan
Participant invests in a Fund. Plan Participants should contact their Plan
administrator, if appropriate, for further information on how to redeem shares
of a Fund. In addition, Qualified Investors and Plan Participants may call the
Distributor at 914-697-8000 for information with respect to the proper procedure
to transmit a redemption request; however, except for redemption requests in
connection with loans under certain Plans and exchanges into other funds as
described below under "Exchange Privileges", redemptions may not be effected
through telephone requests.
 
     Investment return and principal value of an investment in the Funds will
fluctuate, so that the value of shares redeemed may be more or less than the
Qualified Investor's cost. Redemptions of shares may be taxable events to
Qualified Investors otherwise subject to tax on which a Qualified Investor may
realize a gain or a loss. No Fund will make redemptions in kind.
 
     Redemption proceeds normally will be paid or mailed within seven days
following receipt of a redemption request in good order; however, when the NYSE
is closed, when trading on the NYSE is restricted, or when the Securities and
Exchange Commission determines that an emergency exists to warrant such an
action, the Funds may suspend redemption rights or postpone the date of payment.
 
   
     The Trust reserves the right to redeem shares in the account of any
Qualified Investor if at any time the total value of such account falls below
$1,000 for any reason other than a decrease in the net asset value of its
shares. A Qualified Investor will be notified that the value of its account is
less than the minimum amount and allowed 15 days to make an additional
investment before the redemption is processed. Shares will be redeemed at the
net asset value on the date of redemption.
 
     SIGNATURE GUARANTEES.  To protect Qualified Investors and the Trust from
fraud, signature guarantees are required for certain redemptions. Signature
guarantees enable the Trust to be sure that the entity requesting redemption is
the entity that is authorized to request redemption from that account. Signature
guarantees are required for: (1) any redemptions by mail if the proceeds are to
be paid to someone else or are to be sent to an address other than an investor's
address as shown on the Trust's records; (2) any redemptions by mail which
request that the proceeds be wired to a bank, (3) redemption requests for more
than $50,000; and (4) requests to transfer the registration of shares to another
owner. These requirements may be waived in certain instances.
    
 
     The Trust will accept signature guarantees from all institutions which are
eligible to provide them under federal or state law, provided the individual
giving the signature guarantee is authorized to do so. Institutions which
typically are eligible to provide signature guarantees include commercial banks,
trust companies, brokers, dealers, national securities exchanges, savings and
loan associations and credit unions. A signature guarantee is not the same as a
notarized signature.
 
EXCHANGE PRIVILEGES
 
     Subject to applicable legal constraints, Qualified Investors may exchange
their shares in a Fund for shares of other series of the Trust. In addition,
some underlying Plans may provide for exchange privileges with other investment
options available under such Plans. Underlying Plans which include fixed
investment options issued by insurance companies may restrict or prohibit
exchanges of shares of certain of the Funds for shares of other series of the
Trust if the shares of the Fund to be exchanged have been purchased with monies
withdrawn from any such fixed interest investment option.
 
     There are no charges for exchanges. However, Plan Participants should
contact their Plan administrator, if appropriate, for further information
regarding exchanges. In addition, Qualified Investors and Plan Participants may
call the Distributor at 914-697-8000 for information with respect to the proper
procedures to effect such exchanges, including, when appropriate, the procedure
for
 
                                       33
<PAGE>   37
 
effecting such exchanges by telephone. Some Plans may impose charges and
additional restrictions. An exchange order is treated the same as a redemption
followed by a purchase and will be effected at the respective net asset values
of the shares involved.
 
     All Qualified Investors and Plan Participants should be aware that an
exchange transaction authorized by telephone and reasonably believed to be
genuine by the Trust or the Distributor may subject the Qualified Investor or
Plan Participant to risk of loss if such instruction is subsequently found not
to be genuine. The Trust and the Distributor will employ reasonable procedures,
including requiring investors to give certain identification information and
tape recording of telephone instructions, to confirm that instructions
communicated by telephone are genuine. To the extent that the Trust or the
Distributor fail to use reasonable procedures to verify the genuineness of
telephone instructions, they may be liable for any losses due to telephone
instructions that prove to be fraudulent or unauthorized.
 
     The Trust reserves the right to terminate or modify the exchange privilege
in the future.
 
PERFORMANCE INFORMATION
 
     From time to time, the Trust may provide yield and/or total return
quotations for any of the Funds and may also quote fund rankings in the relevant
fund category from various sources, such as Russell Data Services (a division of
Frank Russell Company), Lipper Analytical Services, Inc., Weisenberger
Investment Company Service, Morningstar, Inc. and CDA. The current yield for a
Fund will be calculated by dividing net investment income per share during a
recent 30-day period by the net asset value per share on the last day of the
period and annualizing the resulting quotient. Total return quotations will
reflect the annual percentage change over stated periods in the value of an
investment in a Fund. Yield reflects only net income as of a stated time, while
total return reflects all components of investment return over a stated period
of time. A Fund's quotations may from time to time be used in advertisements,
shareholder reports or other communications to shareholders. For a discussion of
the manner in which a Fund will calculate its yield and total return, see the
Statement of Additional Information.
 
     Investors should note that the investment results of a Fund will fluctuate
over time, and any presentation of a Fund's current yield or total return for
any prior period should not be considered a representation of what an investment
may earn or what an investor's yield or total return may be in any future
period.
 
                               OTHER INFORMATION
 
NET ASSET VALUE
 
   
     The net asset value of shares of the Funds is determined each Fund Business
Day. This determination is made once each day as of the close of regular trading
on the NYSE, currently 4:00 p.m., New York time, by dividing the value of a
Fund's net assets (i.e., the value of its investment in its Portfolio and other
assets less its liabilities, including expenses payable or accrued) by the
number of shares of the Fund outstanding at the time the determination is made.
 
     Each Portfolio values its assets based on their current market value when
market quotations are available. Where market quotations are not available,
assets are valued at fair value as determined in good faith under the direction
of the Portfolio Series' Board of Trustees. Debt obligations with 60 days or
less remaining to maturity may be valued by the amortized cost method which the
Portfolio Series' Trustees have determined to constitute fair value for such
securities.
    
 
                                       34
<PAGE>   38
 
DISTRIBUTIONS
 
     The Funds intend to distribute all net investment income and net capital
gains (i.e., the excess of net long-term capital gains over net short-term
capital losses) to shareholders. Dividends from net investment income (which may
include net short-term capital gains) and distributions from net capital gains,
if any, are normally declared and paid once a year in December. "Net investment
income" includes all dividends, interest and other income earned by a Fund, net
of a Fund's expenses.
 
     All dividends and distributions declared by a Fund will be reinvested in
additional shares of that Fund at net asset value determined on the business day
immediately following the record date of the distribution. A Fund may make
additional distributions if necessary to avoid a 4% federal excise tax on
certain undistributed income and capital gain.
 
TAX MATTERS
 
     The following discussion is for general information only and, specifically,
does not purport to address the taxation of Qualified Investors in all
circumstances or of contributors to, participants in, and beneficiaries under
any Qualified Investor. A prospective investor should consult with its own
adviser as to the tax consequences of an investment in the Trust, including the
state and local tax treatment of distributions from a Fund.
 
   
     Each Fund intends to elect to be, and to qualify to be treated as, a
separate "regulated investment company" under Subchapter M of the Internal
Revenue Code of 1986, as amended (the "Code"). To so qualify, the Funds (through
their interest in the Portfolios) must meet certain income, distribution and
diversification requirements. Provided a Fund meets all such requirements, no
federal income or excise taxes will be required to be paid by that Fund on that
part of its investment company taxable income (consisting generally of net
income and net short-term capital gain, if any) and net capital gain that is
distributed to shareholders. A Fund's foreign source income may, however, be
subject to foreign taxes withheld at the source. The Trust is organized as a
Massachusetts business trust, and under current law the Funds will not be liable
for any income or franchise tax in the Commonwealth of Massachusetts as long as
the Funds qualify as a regulated investment companies under the Code. The
Portfolios will also not be required to pay any federal income or excise taxes.
    
 
     Retirement plans satisfying all conditions applicable to them under the
Code which invest in the Fund generally will not be subject to federal tax
liability on either distributions from the Funds or redemptions of shares of the
Funds. Rather, participants in such Plans will be taxed when they begin taking
distributions from the investing Plan in accordance with the rules under the
Code governing the taxation of such distributions. Qualified Investors otherwise
generally exempt from federal taxation of their income might nevertheless be
taxed on distributions of the Funds, and on any gain realized on redemption of
Fund shares, where the Qualified Investor is subject to the unrelated business
taxable income provisions of the Code with respect to its investment in the
Funds because, e.g., its acquisition of shares in a Fund was financed with debt.
 
   
     If, for any reason, a Qualified Investor is not exempt from income taxation
such Qualified Investor will be subject to tax on distributions received from
the Funds irrespective of the fact that such distributions are reinvested in
additional shares. Distributions to such Investors, other than of net capital
gains, will be taxable as ordinary income; distributions of net capital gains
would be taxable to such Investors as long-term capital gain without regard to
the length of time they have held shares in a Fund. Certain dividends declared
in October, November or December of a calendar year and paid to a Qualified
Investor which is subject to tax on the distribution in January of the
succeeding calendar year are taxable to such Investor as if paid on December 31
of the year in which they were declared.
    
 
     The foregoing is only a summary of some of the important federal tax
considerations generally affecting the Trust and its shareholders. Please refer
to the Statement of Additional Information for a more extensive discussion. In
addition, there may be other federal, state or local tax considerations
 
                                       35
<PAGE>   39
 
applicable to a particular investor. Prospective shareholders are urged to
consult their own tax advisers concerning the tax consequences of an investment
in the Trust.
 
EXPENSES
 
     The respective expenses of the Trust and the Portfolio Series include the
compensation of their respective Trustees who are not affiliated with the
Adviser or any Subadviser; governmental fees; interest charges; taxes; fees and
expenses of independent auditors, of legal counsel and of any transfer agent,
custodian, registrar or dividend disbursing agent of the Trust or the Portfolio
Series; insurance premiums; and expenses of calculating the net asset value of,
and the net income on, interests in the Portfolios and shares of the Funds.
 
     Expenses of the Trust also include all fees under its Administrative
Services Agreement; expenses of distributing and redeeming shares and servicing
shareholder accounts; expenses of preparing, printing and mailing prospectuses,
reports, notices, proxy statements and reports to shareholders and to
governmental officers and commissions; expenses of shareholder and Trustee
meetings; expenses relating to the issuance, registration and qualification of
shares of the Funds and the preparation, printing and mailing of prospectuses
for such purposes; and membership dues in the Investment Company Institute
allocable to the Trust.
 
     Expenses of the Portfolio Series also include expenses connected with the
execution, recording and settlement of security transactions; fees and expenses
of the Portfolio Series' custodian for all services to the Portfolios, including
safekeeping of funds and securities and maintaining required books and accounts;
expenses of preparing and mailing reports to investors and to governmental
officers and commissions; expenses of meetings of investors and Trustees; and
the advisory fees payable to the Adviser under the Advisory Agreements.
 
DESCRIPTION OF SHARES, VOTING RIGHTS AND LIABILITIES
 
     The Trust's Declaration of Trust permits the Trustees to issue an unlimited
number of full and fractional Shares of Beneficial Interest (par value $0.00001
per share) and to divide or combine the shares into a greater or lesser number
of shares without thereby changing the proportionate beneficial interests in the
Trust. The Trust reserves the right to create and issue additional series of
shares, in which case the shares of each series would participate equally in the
earnings, dividends and assets of the particular series.
 
   
     Each share of a Fund represents an equal proportionate interest in that
Fund with each other share. Shares have no preference, preemptive, conversion or
similar rights. Shares when issued are fully paid and nonassessable, except as
set forth below. Shareholders are entitled to one vote for each share held on
matters on which they are entitled to vote. The Trust is not required to and has
no current intention to hold annual meetings of shareholders although the Trust
will hold special meetings of Fund shareholders when in the judgment of the
Trustees of the Trust it is necessary or desirable to submit matters for a
shareholder vote. Shares of each Fund are entitled to vote separately to approve
amendments to the Trust's distribution plan or changes in fundamental investment
policies or restrictions for that Fund, but shares of all Funds will vote
together in the election or selection of Trustees and independent accountants
for the Trust. If requested to do so by 10% of the Trust's outstanding shares, a
meeting of Trust shareholders will be called for the purpose of voting on the
removal of a Trustee or Trustees. The Trust will assist in shareholder
communications as required by Section 16(c) of the 1940 Act.
    
 
     The Trust is an entity of the type commonly known as a "Massachusetts
business trust". Under Massachusetts law, shareholders of such a business trust
may, under certain circumstances, be held personally liable as partners for its
obligations. However, the Trustees of the Trust believe that the risk of a
shareholder incurring financial loss on account of shareholder liability is
limited to circumstances in which both inadequate insurance existed and a Fund
itself was unable to meet its obligations.
 
                                       36
<PAGE>   40
 
     The Portfolio Series is organized as a trust under the laws of the State of
New York. The Portfolio Series' Declaration of Trust provides that each Fund and
other entities investing in a Portfolio (e.g., other investment companies,
insurance company separate accounts and common and commingled trust funds) will
each be liable for all obligations of that Portfolio. However, the Trustees of
the Trust believe that the risk of the Funds incurring financial loss on account
of such liability is limited to circumstances in which both inadequate insurance
existed and the Portfolio itself was unable to meet its obligations. For more
information regarding the Trustees of the Trust and the Portfolio Series, see
"Management of the Trust and Portfolio Series" in the Statement of Additional
Information. The interests in the Portfolio Series are divided into the separate
Portfolios. Investors in each Portfolio will vote separately or together in the
same manner as shareholders of the Funds will vote with respect to the Trust.
 
     Each investor in a Portfolio, including the Trust, may add to or reduce its
investment in a Portfolio on each day the Adviser and applicable Subadviser or
Subadvisers are open for business ("Portfolio Business Day"). As of the close of
regular trading on the NYSE, currently 4:00 p.m., New York time, on each such
day, the value of each investor's beneficial interest in a Portfolio will be
determined by multiplying the net asset value of the Portfolio by the
percentage, effective for that day, which represents that investor's share of
the aggregate beneficial interests in the Portfolio. Any additions or
reductions, which are to be effected as of 4:00 p.m., New York time, on such
day, will then be effected. The investor's percentage of the aggregate
beneficial interests in the Portfolio will then be recomputed as the percentage
equal to the fraction (i) the numerator of which is the value of such investor's
investment in the Portfolio as of 4:00 p.m., New York time, on such day plus or
minus, as the case may be, the amount of net additions to or reductions in the
investor's investment in the Portfolio effected as of 4:00 p.m., New York time,
on such day, and (ii) the denominator of which is the aggregate net asset value
of the Portfolio as of 4:00 p.m., New York time, on such day, plus or minus, as
the case may be, the amount of net additions to or reductions in the aggregate
investments in the Portfolio by all investors in the Portfolio. The percentage
so determined will then be applied to determine the value of the investor's
interest in the Portfolio as of 4:00 p.m., New York time, on the following

                       INVESTMENT OBJECTIVE, POLICIES AND
                            ASSOCIATED RISK FACTORS
 
                             INVESTMENT OBJECTIVES
 
     The investment objective of each Fund and Portfolio is described in the
Funds' Prospectus. There can, of course, be no assurance that a Fund or its
corresponding Portfolio will achieve their investment objective.
 
                              INVESTMENT POLICIES
 
     Each Fund seeks to achieve its investment objective by investing all of its
Assets in its corresponding Portfolio, as shown above. The Trust may withdraw a
Fund's investment from its Portfolio at any time if the Board of Trustees of the
Trust determines that it is in the best interests of the Fund to do so.
 
     Since the investment characteristics of each Fund correspond directly to
those of its corresponding Portfolio, the following supplements the discussions
of the various investments of and techniques employed by the Portfolios set
forth in the Prospectus of the Funds.
 
BANK OBLIGATIONS
 
     Domestic commercial banks organized under federal law are supervised and
examined by the Comptroller of the Currency and are required to be members of
the Federal Reserve System. Domestic banks organized under state law are
supervised and examined by state banking authorities but are members of the
Federal Reserve System only if they elect to join. In addition, state banks are
subject to federal examination and to a substantial body of federal law and
regulation. As a result of federal or state laws and regulations, domestic
banks, among other things, generally are required to maintain specified levels
of reserves, are limited in the amounts which they can loan to a single
borrower, and are subject to other regulations designed to promote financial
soundness. However, not all of such laws and regulations apply to the foreign
branches of domestic banks.
 
     Obligations of foreign branches and subsidiaries of domestic banks and
domestic and foreign branches of foreign banks, such as certificates of deposit
("CDs") and time deposits ("TDs"), may be general obligations of the parent
banks in addition to the issuing branch, or may be limited by the terms of a
specific obligation and governmental regulation. Such obligations are subject to
different risks than are those of domestic banks. These risks include foreign
economic and political developments, foreign governmental restrictions that may
adversely affect payment of principal and interest on the obligations, foreign
exchange controls and foreign withholding and other taxes on interest income.
These foreign branches and subsidiaries are not necessarily subject to the same
or similar regulatory requirements that apply to domestic banks, such as
mandatory reserve requirements, loan limitations, and accounting, auditing and
financial record keeping requirements. In addition, less information may be
publicly available about a foreign branch of a domestic bank or about a foreign
bank than about a domestic bank.
 
     Obligations of United States branches of foreign banks may be general
obligations of the parent bank in addition to the issuing branch, or may be
limited by the terms of a specific obligation and by federal or state regulation
as well as governmental action in the country in which the foreign bank has its
head office. A domestic branch of a foreign bank with assets in excess of $1
billion may be subject to reserve requirements imposed by the Federal Reserve
System or by the state in which the branch is located if the branch is licensed
in that state.
 
     In addition, branches licensed by the Comptroller of the Currency and
branches licensed by certain states may be required to: (1) pledge to the
regulator, by depositing assets with a designated bank within the state, a
certain percentage of their assets as fixed from time to time by the appropriate
regulatory authority; and
 
                                        4
<PAGE>   46
 
(2) maintain assets within the state in an amount equal to a specified
percentage of the aggregate amount of liabilities of the foreign bank payable at
or through all of its agencies or branches within the state.
 
     In view of the foregoing factors associated with the purchase of CDs and
TDs issued by foreign branches of domestic banks, by foreign subsidiaries of
domestic banks, by foreign branches of foreign banks or by domestic branches of
foreign banks, the Advisers carefully evaluate such investments on a
case-by-case basis.
 
U.S. GOVERNMENT AND AGENCY SECURITIES
 
     Securities issued or guaranteed by the U.S. Government or its agencies or
instrumentalities include U.S. Treasury securities, which differ only in their
interest rates, maturities and times of issuance. Treasury Bills have initial
maturities of one year or less; Treasury Notes have initial maturities of one to
ten years; and Treasury Bonds generally have initial maturities of greater than
ten years. Some obligations issued or guaranteed by U.S. Government agencies and
instrumentalities, for example, Government National Mortgage Association
pass-through certificates, are supported by the full faith and credit of the
U.S. Treasury; others, such as those of the Federal Home Loan Banks, by the
right of the issuer to borrow from the Treasury; others, such as those issued by
the Federal National Mortgage Association, by discretionary authority of the
U.S. Government to purchase certain obligations of the agency or
instrumentality; and others, such as those issued by the Student Loan Marketing
Association, only by the credit of the agency or instrumentality. While the U.S.
Government provides financial support to such U.S. Government-sponsored agencies
or instrumentalities, no assurance can be given that it will always do so, since
it is not so obligated by law. A Portfolio will invest in such securities only
when the Advisers are satisfied that the credit risk with respect to the issuer
is minimal.
 
COMMERCIAL PAPER
 
     Commercial paper consists of short-term (usually from 1 to 270 days)
unsecured promissory notes issued by corporations in order to finance their
current operations. A variable amount master demand note (which is a type of
commercial paper) represents a direct borrowing arrangement involving
periodically fluctuating rates of interest under an agreement between a
commercial paper issuer and an institutional lender pursuant to which the lender
may determine to invest varying amounts.
 
     The Portfolios may purchase three types of commercial paper, as classified
by exemption from registration under the Securities Act of 1933, as amended (the
"1933 Act"). The three types include open market, privately placed, and letter
of credit commercial paper. Trading of such commercial paper is conducted
primarily by institutional investors through investment dealers or directly
through the issuers. Individual investor participation in the commercial paper
market is very limited.
 
     OPEN MARKET.  "Open market" commercial paper refers to the commercial paper
of any industrial, commercial, or financial institution which is openly traded,
including directly issued paper. "Open market" paper's 1933 Act exemption is
under Section 3(a)(3) which limits the use of proceeds to current transactions,
limits maturities to 270 days and requires that the paper contain no provision
for automatic rollovers.
 
     PRIVATELY PLACED.  "Privately placed" commercial paper relies on the
exemption from registration provided by Section 4(2), which exempts transactions
by an issuer not involving any public offering. The commercial paper may only be
offered to a limited number of accredited investors. "Privately placed"
commercial paper has no maturity restriction.
 
     LETTER OF CREDIT.  "Letter of credit" commercial paper is exempt from
registration under Section 3(a)(2) of the 1933 Act. It is backed by an
irrevocable or unconditional commitment by a bank to provide funds for repayment
of the notes. Unlike "open market" and "privately placed" commercial paper,
"letter of credit" paper has no limitations on purchases.
 
VARIABLE RATE AND FLOATING RATE SECURITIES
 
     The Portfolios may purchase floating and variable rate demand notes and
bonds, which are obligations ordinarily having stated maturities in excess of
397 days, but which permit the holder to demand payment of
 
                                        5
<PAGE>   47
 
principal at any time, or at specified intervals not exceeding 397 days, in each
case upon not more than 30 days' notice. Variable rate demand notes include
master demand notes which are obligations that permit a Portfolio to invest
fluctuating amounts, which may change daily without penalty, pursuant to direct
arrangements between the Portfolio, as lender, and the borrower. The interest
rates on these notes fluctuate from time to time. The issuer of such obligations
normally has a corresponding right, after a given period, to prepay in its
discretion the outstanding principal amount of the obligations plus accrued
interest upon a specified number of days' notice to the holders of such
obligations. The interest rate on a floating rate demand obligation is based on
a known lending rate, such as a bank's prime rate, and is adjusted automatically
each time such rate is adjusted. The interest rate on a variable rate demand
obligation is adjusted automatically at specified intervals. Frequently, such
obligations are collateralized by letters of credit or other credit support
arrangements provided by banks. Because these obligations are direct lending
arrangements between the lender and borrower, it is not contemplated that such
instruments generally will be traded, and there generally is no established
secondary market for these obligations, although they are redeemable at face
value. Accordingly, where these obligations are not secured by letters of credit
or other credit support arrangements, a Portfolio's right to redeem is dependent
on the ability of the borrower to pay principal and interest on demand. Such
obligations frequently are not rated by credit rating agencies and a Portfolio
may invest in obligations which are not so rated only if the Advisers determine
that at the time of investment the obligations are of comparable quality to the
other obligations in which the Portfolio may invest. The Advisers, on behalf of
a Portfolio, will consider on an ongoing basis the creditworthiness of the
issuers of the floating and variable rate demand obligations held by the
Portfolio. The Portfolios will not invest more than 15% (10% in the case of the
Money Market Portfolio) of the value of their net assets in floating or variable
rate demand obligations as to which they cannot exercise the demand feature on
not more than seven days' notice if there is no secondary market available for
these obligations, and in other securities that are not readily marketable. See
"Investment Restrictions" below.
 
PARTICIPATION INTERESTS
 
     A Portfolio may purchase from financial institutions participation
interests in securities in which such Portfolio may invest. A participation
interest gives a Portfolio an undivided interest in the security in the
proportion that the Portfolio's participation interest bears to the total
principal amount of the security. These instruments may have fixed, floating or
variable rates of interest, with remaining maturities of 13 months or less. If
the participation interest is unrated, or has been given a rating below that
which is permissible for purchase by the Portfolio, the participation interest
will be backed by an irrevocable letter of credit or guarantee of a bank, or the
payment obligation otherwise will be collateralized by U.S. Government
securities, or, in the case of unrated participation interests, the Advisers
must have determined that the instrument is of comparable quality to those
instruments in which a Portfolio may invest. For certain participation
interests, a Portfolio will have the right to demand payment, on not more than
seven days' notice, for all or any part of the Portfolio's participation
interest in the security, plus accrued interest. As to these instruments, a
Portfolio intends to exercise its right to demand payment only upon a default
under the terms of the security, as needed to provide liquidity to meet
redemptions, or to maintain or improve the quality of its investment portfolio.
A Portfolio will not invest more than 15% (10% in the case of the Money Market
Portfolio) of its net assets in participation interests that do not have this
demand feature, and in other securities that are not readily marketable. See
"Investment Restrictions" below.
 
ILLIQUID SECURITIES
 
     Historically, illiquid securities have included securities subject to
contractual or legal restrictions on resale because they have not been
registered under the 1933 Act, securities which are otherwise not readily
marketable and repurchase agreements having a maturity of longer than seven
days. Securities which have not been registered under the 1933 Act are referred
to as private placements or restricted securities and are purchased directly
from the issuer or in the secondary market. Mutual funds do not typically hold a
significant amount of these restricted or other illiquid securities because of
the potential for delays on resale and uncertainty in valuation. Limitations on
resale may have an adverse effect on the marketability of portfolio securities
and a mutual fund might be unable to dispose of restricted or other illiquid
securities promptly or at
 
                                        6
<PAGE>   48
 
reasonable prices and might thereby experience difficulty satisfying redemptions
within seven days. A mutual fund might also have to register such restricted
securities in order to dispose of them which, if possible at all, would result
in additional expense and delay. Adverse market conditions could impede such a
public offering of securities.
 
     In recent years, however, a large institutional market has developed for
certain securities that are not registered under the 1933 Act, including
repurchase agreements, commercial paper, foreign securities, municipal
securities and corporate bonds and notes. Institutional investors depend on an
efficient institutional market in which the unregistered security can be readily
resold or on an issuer's ability to honor a demand for repayment. The fact that
there are contractual or legal restrictions on resale of such investments to the
general public or to certain institutions may not be indicative of their
liquidity.
 
     The Securities and Exchange Commission (the "SEC") has recently adopted
Rule 144A, which allows a broader institutional trading market for securities
otherwise subject to restriction on their resale to the general public. Rule
144A establishes a "safe harbor" from the registration requirements of the 1933
Act for resales of certain securities to qualified institutional buyers.
 
     The Advisers will monitor the liquidity of Rule 144A securities for each
Portfolio under the supervision of the Portfolio's Board of Trustees. In
reaching liquidity decisions, the Advisers will consider, among other things,
the following factors: (1) the frequency of trades and quotes for the security,
(2) the number of dealers and other potential purchasers wishing to purchase or
sell the security, (3) dealer undertakings to make a market in the security and
(4) the nature of the security and of the marketplace trades (e.g., the time
needed to dispose of the security, the method of soliciting offers and the
mechanics of the transfer).
 
UNSECURED PROMISSORY NOTES
 
     A Portfolio also may purchase unsecured promissory notes ("Notes") which
are not readily marketable and have not been registered under the 1933 Act,
provided such investments are consistent with the Portfolio's investment
objective. The Notes purchased by the Portfolio will have remaining maturities
of 13 months or less and will be deemed by the Board of Trustees of the
Portfolio to present minimal credit risks and will meet the quality criteria set
forth above under "Investment Policies." The Portfolio will invest no more than
15% (10% in the case of the Money Market Portfolio) of its net assets in such
Notes and in other securities that are not readily marketable (which securities
would include floating and variable rate demand obligations as to which the
Portfolio cannot exercise the demand feature described above and as to which
there is no secondary market). See "Investment Restrictions" below.
 
REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS
 
     Repurchase agreements are agreements by which a person purchases a security
and simultaneously commits to resell that security to the seller (which is
usually a member bank of the Federal Reserve System or a member firm of the New
York Stock Exchange (or a subsidiary thereof)) at an agreed-upon date within a
number of days (usually not more than seven) from the date of purchase. The
resale price reflects the purchase price plus an agreed-upon market rate of
interest which is unrelated to the coupon rate or maturity of the purchased
security. A repurchase agreement involves the obligation of the seller to pay
the agreed-upon price, which obligation is in effect secured by the value of the
underlying security, usually U.S. Government or government agency issues. Under
the Investment Company Act of 1940, as amended (the "1940 Act"), repurchase
agreements may be considered to be loans by the buyer. A Portfolio's risk is
limited to the ability of the seller to pay the agreed upon amount on the
delivery date. If the seller defaults, the underlying security constitutes
collateral for the seller's obligation to pay although a Portfolio may incur
certain costs in liquidating this collateral and in certain cases may not be
permitted to liquidate this collateral. All repurchase agreements entered into
by the Portfolios are fully collateralized, with such collateral being marked to
market daily.
 
     The Portfolios may borrow funds for temporary or emergency purposes, such
as meeting larger than anticipated redemption requests, and not for leverage.
One means of borrowing is by agreeing to sell portfolio securities to financial
institutions such as banks and broker-dealers and to repurchase them at a
mutually
 
                                        7
<PAGE>   49
 
agreed date and price (a "reverse repurchase agreement"). At the time a
Portfolio enters into a reverse repurchase agreement it will place in a
segregated custodial account cash, U.S. Government securities or high-grade debt
obligations having a value equal to the repurchase price, including accrued
interest. Reverse repurchase agreements involve the risk that the market value
of the securities sold by the Portfolio may decline below the repurchase price
of those securities.
 
FOREIGN SECURITIES -- ALL PORTFOLIOS
 
     The Portfolios may invest their assets in securities of foreign issuers.
Investing in securities issued by companies whose principal business activities
are outside the United States may involve significant risks not present in
domestic investments. For example, there is generally less publicly available
information about foreign companies, particularly those not subject to the
disclosure and reporting requirements of the U.S. securities laws. Foreign
issuers are generally not bound by uniform accounting, auditing and financial
reporting requirements comparable to those applicable to domestic issuers.
Investments in foreign securities also involve the risk of possible adverse
changes in investment or exchange control regulations, expropriation or
confiscatory taxation, brokerage or other taxation, limitation on the removal of
funds or other assets of a Portfolio, political or financial instability or
diplomatic and other developments which would affect such investments. Further,
economies of particular countries or areas of the world may differ favorably or
unfavorably from the economy of the United States.
 
     It is anticipated that in most cases the best available market for foreign
securities would be on exchanges or in over-the-counter markets located outside
the United States. Foreign stock markets, while growing in volume and
sophistication, are generally not as developed as those in the United States,
and securities of some foreign issuers (particularly those located in developing
countries) may be less liquid and more volatile than securities of comparable
United States companies. Foreign security trading practices, including those
involving securities settlement where a Portfolio's assets may be released prior
to receipt of payment, may expose a Portfolio to increased risk in the event of
a failed trade or the insolvency of a foreign broker-dealer. In addition,
foreign brokerage commissions are generally higher than commissions on
securities traded in the United States and may be non-negotiable. In general,
there is less overall governmental supervision and regulation of foreign
securities exchanges, brokers and listed companies than in the United States.
 
FOREIGN SECURITIES -- MONEY MARKET PORTFOLIO
 
     The Money Market Portfolio may invest in the following foreign securities:
(i) U.S. dollar-denominated obligations of foreign branches and subsidiaries of
domestic banks and foreign banks (such as Eurodollar CDs, which are U.S.
dollar-denominated CDs issued by branches of foreign and domestic banks located
outside the United States; Eurodollar TDs ("ETDs"), which are U.S.
dollar-denominated deposits in a foreign branch of a foreign or domestic bank;
and Canadian TDs, which are essentially the same as ETDs except they are issued
by branches of major Canadian banks), (ii) high quality, U.S. dollar-denominated
short-term bonds and notes (including variable amount master demand notes)
issued by foreign corporations, (including Canadian commercial paper, which is
commercial paper issued by a Canadian corporation or a Canadian counterpart of a
U.S. corporation, and Europaper, which is U.S. dollar-denominated commercial
paper of a foreign issuer) and (iii) U.S. dollar-denominated obligations issued
or guaranteed by one or more foreign governments or any of their political
subdivisions, agencies or instrumentalities that are determined by the Adviser
to be of comparable quality to the other obligations in which the Money Market
Portfolio may invest. Such securities also include debt obligations of
supranational entities. Supranational entities include international
organizations designated or supported by governmental entities to promote
economic reconstruction or development and international banking institutions
and related government agencies. Examples include the International Bank for
Reconstruction and Development (the World Bank), the European Coal and Steel
Community, the Asian Development Bank and the InterAmerican Development Bank.
 
FOREIGN SECURITIES -- PORTFOLIOS OTHER THAN MONEY MARKET PORTFOLIO
 
     Not more than 5% of a Portfolio's assets may be invested in closed-end
investment companies which primarily hold foreign securities. Investments in
such companies may entail the risk that the market value of
 
                                        8
<PAGE>   50
 
such investments may be substantially less than their net asset value and that
there would be duplication of investment management and other fees and expenses.
Securities of foreign issuers include investments in sponsored American
Depository Receipts ("ADRs"). ADRs are depository receipts for securities of
foreign issuers and provide an alternative method for a Portfolio to make
foreign investments. These securities will not be denominated in the same
currency as the securities into which they may be converted. Generally, ADRs, in
registered form, are designed for use in U.S. securities markets. ADRs are
receipts typically issued by a U.S. bank or trust company evidencing ownership
of the underlying securities.
 
     The Portfolios may invest in foreign securities that impose restrictions on
transfer within the United States or to United States persons. Although
securities subject to such transfer restrictions may be marketable abroad, they
may be less liquid than foreign securities of the same class that are not
subject to such restrictions.
 
FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS
 
     Because some Portfolios may buy and sell securities denominated in
currencies other than the U.S. dollar and receive interest, dividends and sale
proceeds in currencies other than the U.S. dollar, the Portfolios from time to
time may enter into foreign currency exchange transactions to convert to and
from different foreign currencies and to convert foreign currencies to and from
the U.S. dollar. The Portfolios either enter into these transactions on a spot
(i.e., cash) basis at the spot rate prevailing in the foreign currency exchange
market or use forward contracts to purchase or sell foreign currencies.
 
     A forward foreign currency exchange contract is an obligation by a
Portfolio to purchase or sell a specific currency at a future date, which may be
any fixed number of days from the date of the contract. Forward foreign currency
exchange contracts establish an exchange rate at a future date. These contracts
are transferable in the interbank market conducted directly between currency
traders (usually large commercial banks) and their customers. A forward foreign
currency exchange contract generally has no deposit requirement and is traded at
a net price without commission. A Portfolio maintains with its custodian a
segregated account of high grade liquid assets in an amount at least equal to
its obligations under each forward foreign currency exchange contract. Neither
spot transactions nor forward foreign currency exchange contracts eliminate
fluctuations in the prices of the Portfolio's securities or in foreign exchange
rates, or prevent loss if the prices of these securities should decline.
 
     The Portfolios may enter into foreign currency hedging transactions in an
attempt to protect against changes in foreign currency exchange rates between
the trade and settlement dates of specific securities transactions or changes in
foreign currency exchange rates that would adversely affect a portfolio position
or an anticipated investment position. With respect to Portfolios other than the
International Equity Portfolios consideration of the prospect for currency
parities will be incorporated into the Advisers' long-term investment decisions,
therefore these Portfolios will not routinely enter into foreign currency
hedging transactions with respect to security transactions; however, the
Advisers believe that it is important to have the flexibility to enter into
foreign currency hedging transactions when they determine that the transactions
would be in a Portfolio's best interest. Although these transactions tend to
minimize the risk of loss due to a decline in the value of the hedged currency,
at the same time they tend to limit any potential gain that might be realized
should the value of the hedged currency increase. The precise matching of the
forward contract amounts and the value of the securities involved will not
generally be possible because the future value of such securities in foreign
currencies will change as a consequence of market movements in the value of such
securities between the date the forward contract is entered into and the date it
matures. The projection of currency market movements is extremely difficult, and
the successful execution of a hedging strategy is highly uncertain.
 
     While these contracts are not presently regulated by the Commodity Futures
Trading Commission ("CFTC"), the CFTC may in the future assert authority to
regulate forward contracts. In such event a Portfolio's ability to utilize
forward contracts in the manner set forth in the Prospectus may be restricted.
Forward contracts may reduce the potential gain from a positive change in the
relationship between the U.S. dollar and foreign currencies. Unanticipated
changes in currency prices may result in poorer overall performance for a
Portfolio than if it had not entered into such contracts. The use of foreign
currency forward
 
                                        9
<PAGE>   51
 
contracts may not eliminate fluctuations in the underlying U.S. dollar
equivalent value of the prices of or rates of return on a Portfolio's foreign
currency denominated portfolio securities and the use of such techniques will
subject the Portfolio to certain risks.
 
     The matching of the increase in value of a forward contract and the decline
in the U.S. dollar equivalent value of the foreign currency denominated asset
that is the subject of the hedge generally will not be precise. In addition, a
Portfolio may not always be able to enter into foreign currency forward
contracts at attractive prices and this will limit a Portfolio's ability to use
such contract to hedge or cross-hedge its assets. Also, with regard to a
Portfolio's use of cross-hedges, there can be no assurance that historical
correlations between the movement of certain foreign currencies relative to the
U.S. dollar will continue. Thus, at any time poor correlation may exist between
movements in the exchange rates of the foreign currencies underlying a
Portfolio's crosshedges and the movements in the exchange rates of the foreign
currencies in which the Portfolio's assets that are the subject of such
cross-hedges are denominated.
 
GUARANTEED INVESTMENT CONTRACTS
 
     The Portfolios may invest in guaranteed investment contracts ("GICs")
issued by insurance companies. Pursuant to such contracts, a Portfolio makes
cash contributions to a deposit fund of the insurance company's general account.
The insurance company then credits to the fund guaranteed interest. The GICs
provide that this guaranteed interest will not be less than a certain minimum
rate. The insurance company may assess periodic charges against a GIC for
expenses and service costs allocable to it, and the charges will be deducted
from the value of the deposit fund. Because a Portfolio may not receive the
principal amount of a GIC from the insurance company on seven days' notice or
less, the GIC is considered an illiquid investment and, together with other
instruments in a Portfolio which are not readily marketable, will not exceed 15%
(10% in the case of the Money Market Portfolio) of the Portfolio's net assets.
The term of a GIC will be 13 months or less. In determining average weighted
portfolio maturity, a GIC will be deemed to have a maturity equal to the longer
of the period of time remaining until the next readjustment of the guaranteed
interest rate or the period of time remaining until the principal amount can be
recovered from the issuer through demand.
 
WHEN-ISSUED SECURITIES
 
     The Portfolios may purchase securities on a "when-issued" or on a "forward
delivery" basis. It is expected that, under normal circumstances, the Portfolios
would take delivery of such securities. When a Portfolio commits to purchase a
security on a "when-issued" or on a "forward delivery" basis, the Portfolio
establishes procedures consistent with the relevant policies of the SEC. Since
those policies currently recommend that an amount of a Portfolio's assets equal
to the amount of the purchase be held aside or segregated to be used to pay for
the commitment, the Portfolio expects always to have cash, cash equivalents, or
high quality debt securities sufficient to cover any commitments or to limit any
potential risk. However, although a Portfolio does not intend to make such
purchases for speculative purposes and intends to adhere to the provisions of
SEC policies, purchases of securities on such bases may involve more risk than
other types of purchases. For example, a Portfolio may have to sell assets which
have been set aside in order to meet redemptions. Also, if a Portfolio
determines it is advisable as a matter of investment strategy to sell the "when-
issued" or "forward delivery" securities, a Portfolio would be required to meet
its obligations from the then available cash flow or the sale of securities, or,
although it would not normally expect to do so, from the sale of the
"when-issued" or "forward delivery" securities themselves (which may have a
value greater or less than the Portfolio's payment obligation).
 
ZERO COUPON OBLIGATIONS
 
     A Portfolio may acquire zero coupon obligations when consistent with its
investment objective and policies. Such obligations have greater price
volatility than coupon obligations and will not result in payment of interest
until maturity. Since dividend income is accrued throughout the term of the zero
coupon obligation but is not actually received until maturity, a Portfolio may
have to sell other securities to pay said accrued dividends prior to maturity of
the zero coupon obligation.
 
                                       10

FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS --
  PORTFOLIOS OTHER THAN MONEY MARKET PORTFOLIO
 
     General.  The successful use of such instruments draws upon the Advisers'
skill and experience with respect to such instruments. Should interest or
exchange rates move in an unexpected manner, a Portfolio may not achieve the
anticipated benefits of futures contracts or options on futures contracts or may
realize losses and thus will be in a worse position than if such strategies had
not been used. In addition, the correlation between movements in the price of
futures contracts or options on futures contracts and movements in the price of
the securities and currencies hedged or used for cover will not be perfect and
could produce unanticipated losses.
 
     Futures Contracts.  A Portfolio may enter into contracts for the purchase
or sale for future delivery of fixed-income securities or foreign currencies, or
contracts based on financial indices including any index of U.S. Government
securities, foreign government securities or corporate debt securities. U.S.
futures contracts have been designed by exchanges which have been designated
"contracts markets" by the CFTC, and must be executed through a futures
commission merchant, or brokerage firm, which is a member of the relevant
contract market. Futures contracts trade on a number of exchange markets, and,
through their clearing corporations, the exchanges guarantee performance of the
contracts as between the clearing members of the exchange. A Portfolio may enter
into futures contracts which are based on debt securities that are backed by the
full faith and credit of the U.S. Government, such as long-term U.S. Treasury
Bonds, Treasury Notes, Government National Mortgage Association modified
pass-through mortgage-backed securities and three-month U.S. Treasury Bills. A
Portfolio may also enter into futures contracts which are based on bonds issued
by entities other than the U.S. Government.
 
     Purchases or sales of stock index futures contracts are used to attempt to
protect the Portfolio's current or intended stock investments from broad
fluctuations in stock prices. For example, the Portfolio may sell stock index
futures contracts in anticipation of or during a decline in the market value of
the Portfolio's securities. If such decline occurs, the loss in value of
portfolio securities may be offset, in whole or part, by gains on the futures
position. When a Portfolio is not fully invested in the securities market and
anticipates a significant market advance, it may purchase stock index futures
contracts in order to gain rapid market exposure that may, in part or entirely,
offset increases in the cost of securities that the Portfolio intends to
purchase. As such purchases are made, the corresponding positions in stock index
futures contracts will be closed out. In a substantial majority of these
transactions, the Portfolio will purchase such securities upon termination of
the futures position, but under unusual market conditions, a long futures
position may be terminated without a related purchase of securities.
 
     At the same time a futures contract is purchased or sold, the Portfolio
must allocate cash or securities as a deposit payment ("initial deposit"). It is
expected that the initial deposit would be approximately 1/2% to 5% of a
contract's face value. Daily thereafter, the futures contract is valued and the
payment of "variation margin" may be required, since each day the Portfolio
would provide or receive cash that reflects any decline or increase in the
contract's value.
 
     At the time of delivery of securities pursuant to such a contract,
adjustments are made to recognize differences in value arising from the delivery
of securities with a different interest rate from that specified in the
contract. In some (but not many) cases, securities called for by a futures
contract may not have been issued when the contract was written.
 
     Although futures contracts by their terms call for the actual delivery or
acquisition of securities, in most cases the contractual obligation is fulfilled
before the date of the contract without having to make or take delivery of the
securities. The offsetting of a contractual obligation is accomplished by buying
(or selling, as the case may be) on a commodities exchange an identical futures
contract calling for delivery in the same month. Such a transaction, which is
effected through a member of an exchange, cancels the obligation to make or take
delivery of the securities. Since all transactions in the futures market are
made, offset or fulfilled through a clearinghouse associated with the exchange
on which the contracts are traded, a Portfolio will incur brokerage fees when it
purchases or sells futures contracts.
 
                                       11
<PAGE>   53
 
     The purpose of the acquisition or sale of a futures contract, in the case
of a Portfolio which holds or intends to acquire fixed-income securities, is to
attempt to protect the Portfolio from fluctuations in interest or foreign
exchange rates without actually buying or selling fixed-income securities or
foreign currencies. For example, if interest rates were expected to increase, a
Portfolio might enter into futures contracts for the sale of debt securities.
Such a sale would have much the same effect as selling an equivalent value of
the debt securities owned by the Portfolio. If interest rates did increase, the
value of the debt security in a Portfolio would decline, but the value of the
futures contracts to the Portfolio would increase at approximately the same
rate, thereby keeping the net asset value of the Portfolio from declining as
much as it otherwise would have. The Portfolio could accomplish similar results
by selling debt securities and investing in bonds with short maturities when
interest rates are expected to increase. However, since the futures market is
more liquid than the cash market, the use of futures contracts as an investment
technique allows a Portfolio to maintain a defensive position without having to
sell its portfolio securities.
 
     Similarly, when it is expected that interest rates may decline, futures
contracts may be purchased to attempt to hedge against anticipated purchases of
debt securities at higher prices. Since the fluctuations in the value of futures
contracts should be similar to those of debt securities, a Portfolio could take
advantage of the anticipated rise in the value of debt securities without
actually buying them until the market had stabilized. At that time, the futures
contracts could be liquidated and the Portfolio could then buy debt securities
on the cash market. To the extent a Portfolio enters into futures contracts for
this purpose, the assets in the segregated asset account maintained to cover the
Portfolio's obligations with respect to such futures contracts will consist of
cash, cash equivalents or high quality liquid debt securities from its portfolio
in an amount equal to the difference between the fluctuating market value of
such futures contracts and the aggregate value of the initial and variation
margin payments made by the Portfolio with respect to such futures contracts.
 
     The ordinary spreads between prices in the cash and futures market, due to
differences in the nature of those markets, are subject to distortions. First,
all participants in the futures market are subject to initial deposit and
variation margin requirements. Rather than meeting additional variation margin
requirements, investors may close futures contracts through offsetting
transactions which could distort the normal relationship between the cash and
futures markets. Second, the liquidity of the futures market depends on
participants entering into offsetting transactions rather than making or taking
delivery. To the extent participants decide to make or take delivery, liquidity
in the futures market could be reduced, thus producing distortion. Third, from
the point of view of speculators, the margin deposit requirements in the futures
market are less onerous than margin requirements in the securities market.
Therefore, increased participation by speculators in the futures market may
cause temporary price distortions. Due to the possibility of distortion, a
correct forecast of general interest rate trends by the Advisers may still not
result in a successful transaction.
 
     In addition, futures contracts entail risks. Although the Advisers believe
that use of such contracts will benefit the Portfolios, if the Advisers'
investment judgment about the general direction of interest rates is incorrect,
a Portfolio's overall performance would be poorer than if it had not entered
into any such contract. For example, if a Portfolio has hedged against the
possibility of an increase in interest rates which would adversely affect the
price of debt securities held by it and interest rates decrease instead, the
Portfolio will lose part or all of the benefit of the increased value of its
debt securities which it has hedged because it will have offsetting losses in
its futures positions. In addition, in such situations, if a Portfolio has
insufficient cash, it may have to sell debt securities to meet daily variation
margin requirements. Such sales of bonds may be, but will not necessarily be, at
increased prices which reflect the rising market. A Portfolio may have to sell
securities at a time when it may be disadvantageous to do so.
 
     Options on Futures Contracts.  The Portfolios intend to purchase and write
options on futures contracts for hedging purposes. The purchase of a call option
on a futures contract is similar in some respects to the purchase of a call
option on an individual security. Depending on the pricing of the option
compared to either the price of the futures contract upon which it is based or
the price of the underlying debt securities, it may or may not be less risky
than ownership of the futures contract or underlying debt securities. As with
the purchase of futures contracts, when a Portfolio is not fully invested it may
purchase a call option on a futures contract to hedge against a market advance
due to declining interest rates.
 
                                       12
<PAGE>   54
 
     The writing of a call option on a futures contract constitutes a partial
hedge against declining prices of the security or foreign currency which is
deliverable upon exercise of the futures contract. If the futures price at
expiration of the option is below the exercise price, a Portfolio will retain
the full amount of the option premium which provides a partial hedge against any
decline that may have occurred in the Portfolio's portfolio holdings. The
writing of a put option on a futures contract constitutes a partial hedge
against increasing prices of the security or foreign currency which is
deliverable upon exercise of the futures contract. If the futures price at
expiration of the option is higher than the exercise price, the Portfolio will
retain the full amount of the option premium which provides a partial hedge
against any increase in the price of securities which the Portfolio intends to
purchase. If a put or call option the Portfolio has written is exercised, the
Portfolio will incur a loss which will be reduced by the amount of the premium
it receives. Depending on the degree of correlation between changes in the value
of its portfolio securities and changes in the value of its futures positions,
the Portfolio's losses from existing options on futures may to some extent be
reduced or increased by changes in the value of portfolio securities.
 
     The purchase of a put option on a futures contract is similar in some
respects to the purchase of protective put options on portfolio securities. For
example, a Portfolio may purchase a put option on a futures contract to hedge
its portfolio against the risk of rising interest rates.
 
     The amount of risk a Portfolio assumes when it purchases an option on a
futures contract is the premium paid for the option plus related transaction
costs. In addition to the correlation risks discussed above, the purchase of an
option also entails the risk that changes in the value of the underlying futures
contract will not be fully reflected in the value of the option purchased.
 
     The Board of Trustees of the Portfolio has adopted the requirement that
futures contracts and options on futures contracts be used either (i) as a hedge
without regard to any quantitative limitation, or (ii) for other purposes to the
extent that immediately thereafter the aggregate amount of margin deposits on
all (non-hedge) futures contracts of the Portfolio and premiums paid on
outstanding (non-hedge) options on futures contracts owned by the Portfolio does
not exceed 5% of the market value of the total assets of the Portfolio. In
addition, the aggregate market value of the outstanding futures contracts
purchased by the Portfolio may not exceed 50% of the market value of the total
assets of the Portfolio. Neither of these restrictions will be changed by the
Portfolio's Board of Trustees without considering the policies and concerns of
the various applicable federal and state regulatory agencies.
 
     Options on Foreign Currencies.  A Portfolio may purchase and write options
on foreign currencies for hedging purposes in a manner similar to that in which
futures contracts on foreign currencies, or forward contracts, will be utilized.
For example, a decline in the dollar value of a foreign currency in which
portfolio securities are denominated will reduce the dollar value of such
securities, even if their value in the foreign currency remains constant. In
order to protect against such diminutions in the value of portfolio securities,
the Portfolio may purchase put options on the foreign currency. If the value of
the currency does decline, a Portfolio will have the right to sell such currency
for a fixed amount in dollars and will thereby offset, in whole or in part, the
adverse effect on its portfolio which otherwise would have resulted.
 
     Conversely, where a rise in the dollar value of a currency in which
securities to be acquired are denominated is projected, thereby increasing the
cost of such securities, the Portfolio may purchase call options thereon. The
purchase of such options could offset, at least partially, the effects of the
adverse movements in exchange rates. As in the case of other types of options,
however, the benefit to the Portfolio deriving from purchases of foreign
currency options will be reduced by the amount of the premium and related
transaction costs. In addition, where currency exchange rates do not move in the
direction or to the extent anticipated, the Portfolio could sustain losses on
transactions in foreign currency options which would require it to forego a
portion or all of the benefits of advantageous changes in such rates.
 
     A Portfolio may write options on foreign currencies for the same types of
hedging purposes. For example, where a Portfolio anticipates a decline in the
dollar value of foreign currency denominated securities due to adverse
fluctuations in exchange rates it could, instead of purchasing a put option,
write a call option on the relevant currency. If the expected decline occurs,
the options will most likely not be exercised, and the diminution in value of
portfolio securities will be offset by the amount of the premium received.
 
                                       13
<PAGE>   55
 
     Similarly, instead of purchasing a call option to hedge against an
anticipated increase in the dollar cost of securities to be acquired, the
Portfolio could write a put option on the relevant currency which, if rates move
in the manner projected, will expire unexercised and allow the Portfolio to
hedge such increased cost up to the amount of the premium. As in the case of
other types of options, however, the writing of a foreign currency option will
constitute only a partial hedge up to the amount of the premium, and only if
rates move in the expected direction. If this does not occur, the option may be
exercised and the Portfolio would be required to purchase or sell the underlying
currency at a loss which may not be offset by the amount of the premium. Through
the writing of options on foreign currencies, the Portfolio also may be required
to forego all or a portion of the benefits which might otherwise have been
obtained from favorable movements in exchange rates.
 
     The Portfolios intend to write covered call options on foreign currencies.
A call option written on a foreign currency by a Portfolio is "covered" if the
Portfolio owns the underlying foreign currency covered by the call or has an
absolute and immediate right to acquire that foreign currency without additional
cash consideration (or for additional cash consideration held in a segregated
account by its custodian) upon conversion or exchange of other foreign currency
held in its portfolio. A call option is also covered if the Portfolio has a call
on the same foreign currency and in the same principal amount as the call
written where the exercise price of the call held (a) is equal to or less than
the exercise price of the call written or (b) is greater than the exercise price
of the call written if the difference is maintained by the Portfolio in cash,
U.S. Government securities and other high quality liquid debt securities in a
segregated account with its custodian.
 
     The Portfolios also intend to write call options on foreign currencies that
are not covered for cross-hedging purposes. A call option on a foreign currency
is for cross-hedging purposes if it is not covered, but is designed to provide a
hedge against a decline in the U.S. dollar value of a security which the
Portfolio owns or has the right to acquire and which is denominated in the
currency underlying the option due to an adverse change in the exchange rate. In
such circumstances, the Portfolio collateralizes the option by maintaining in a
segregated account with its custodian, cash or U.S. Government securities or
other high quality liquid debt securities in an amount not less than the value
of the underlying foreign currency in U.S. dollars marked to market daily.
 
     Additional Risks of Options on Futures Contracts, Forward Contracts and
Options on Foreign Currencies. Unlike transactions entered into by a Portfolio
in futures contracts, options on foreign currencies and forward contracts are
not traded on contract markets regulated by the CFTC or (with the exception of
certain foreign currency options) by the SEC. To the contrary, such instruments
are traded through financial institutions acting as market-makers, although
foreign currency options are also traded on certain national securities
exchanges, such as the Philadelphia Stock Exchange and the Chicago Board Options
Exchange, subject to SEC regulation. Similarly, options on currencies may be
traded over-the-counter. In an over-the-counter trading environment, many of the
protections afforded to exchange participants will not be available. For
example, there are no daily price fluctuation limits, and adverse market
movements could therefore continue to an unlimited extent over a period of time.
Although the purchaser of an option cannot lose more than the amount of the
premium plus related transaction costs, this entire amount could be lost.
Moreover, the option writer and a trader of forward contracts could lose amounts
substantially in excess of their initial investments, due to the margin and
collateral requirements associated with such positions.
 
     Options on foreign currencies traded on national securities exchanges are
within the jurisdiction of the SEC, as are other securities traded on such
exchanges. As a result, many of the protections provided to traders on organized
exchanges will be available with respect to such transactions. In particular,
all foreign currency option positions entered into on a national securities
exchange are cleared and guaranteed by the Options Clearing Corporation ("OCC"),
thereby reducing the risk of counterparty default. Further, a liquid secondary
market in options traded on a national securities exchange may be more readily
available than in the over-the-counter market, potentially permitting a
Portfolio to liquidate open positions at a profit prior to exercise or
expiration, or to limit losses in the event of adverse market movements.
 
     The purchase and sale of exchange-traded foreign currency options, however,
is subject to the risks of the availability of a liquid secondary market
described above, as well as the risks regarding adverse market
 
                                       14
<PAGE>   56
 
movements, margining of options written, the nature of the foreign currency
market, possible intervention by governmental authorities and the effects of
other political and economic events. In addition, exchange-traded options on
foreign currencies involve certain risks not presented by the over-the-counter
market. For example, exercise and settlement of such options must be made
exclusively through the OCC, which has established banking relationships in
applicable foreign countries for this purpose. As a result, the OCC may, if it
determines that foreign governmental restrictions or taxes would prevent the
orderly settlement of foreign currency option exercises, or would result in
undue burdens on the OCC or its clearing member, impose special procedures on
exercise and settlement, such as technical changes in the mechanics of delivery
of currency, the fixing of dollar settlement prices or prohibitions on exercise.
 
     As in the case of forward contracts, certain options on foreign currencies
are traded over-the-counter and involve liquidity and credit risks which may not
be present in the case of exchange-traded currency options. A Portfolio's
ability to terminate over-the-counter options will be more limited than with
exchange-traded options. It is also possible that broker-dealers participating
in over-the-counter options transactions will not fulfill their obligations.
Until such time as the staff of the SEC changes its position, each Portfolio
will treat purchased over-the-counter options and assets used to cover written
over-the-counter options as illiquid securities. With respect to options written
with primary dealers in U.S. Government securities pursuant to an agreement
requiring a closing purchase transaction at a formula price, the amount of
illiquid securities may be calculated with reference to the repurchase formula.
 
     In addition, futures contracts, options on futures contracts, forward
contracts and options on foreign currencies may be traded on foreign exchanges.
Such transactions are subject to the risk of governmental actions affecting
trading in or the prices of foreign currencies or securities. The value of such
positions also could be adversely affected by (i) other complex foreign
political and economic factors, (ii) lesser availability than in the United
States of data on which to make trading decisions, (iii) delays in the
Portfolio's ability to act upon economic events occurring in foreign markets
during nonbusiness hours in the United States, (iv) the imposition of different
exercise and settlement terms and procedures and margin requirements than in the
United States, and (v) lesser trading volume.
 
OPTIONS ON SECURITIES -- PORTFOLIOS OTHER THAN MONEY MARKET PORTFOLIO
 
     The Portfolios may write (sell) covered call and put options to a limited
extent on its portfolio securities ("covered options"). However, a Portfolio may
forego the benefits of appreciation on securities sold or may pay more than the
market price on securities acquired pursuant to call and put options written by
the Portfolio.
 
     When a Portfolio writes a covered call option, it gives the purchaser of
the option the right to buy the underlying security at the price specified in
the option (the "exercise price") by exercising the option at any time during
the option period. If the option expires unexercised, the Portfolio will realize
income in an amount equal to the premium received for writing the option. If the
option is exercised, a decision over which a Portfolio has no control, the
Portfolio must sell the underlying security to the option holder at the exercise
price. By writing a covered call option, a Portfolio forgoes, in exchange for
the premium less the commission ("net premium"), the opportunity to profit
during the option period from an increase in the market value of the underlying
security above the exercise price.
 
     When a Portfolio writes a covered put option, it gives the purchaser of the
option the right to sell the underlying security to the Portfolio at the
specified exercise price at any time during the option period. If the option
expires unexercised, the Portfolio will realize income in the amount of the
premium received for writing the option. If the put option is exercised, a
decision over which a Portfolio has no control, the Portfolio must purchase the
underlying security from the option holder at the exercise price. By writing a
covered put option, a Portfolio, in exchange for the net premium received,
accepts the risk of a decline in the market value of the underlying security
below the exercise price. A Portfolio will only write put options involving
securities for which a determination is made at the time the option is written
that the Portfolio wishes to acquire the securities at the exercise price.
 
     A Portfolio may terminate its obligation as the writer of a call or put
option by purchasing an option with the same exercise price and expiration date
as the option previously written. This transaction is called a
 
                                       15
<PAGE>   57
 
"closing purchase transaction." Where a Portfolio cannot effect a closing
purchase transaction, it may be forced to incur brokerage commissions or dealer
spreads in selling securities it receives or it may be forced to hold underlying
securities until an option is exercised or expires.
 
     When a Portfolio writes an option, an amount equal to the net premium
received by the Portfolio is included in the liability section of the
Portfolio's Statement of Assets and Liabilities as a deferred credit. The amount
of the deferred credit will be subsequently marked to market to reflect the
current market value of the option written. The current market value of a traded
option is the last sale price or, in the absence of a sale, the mean between the
closing bid and asked price. If an option expires on its stipulated expiration
date or if the Portfolio enters into a closing purchase transaction, the
Portfolio will realize a gain (or loss if the cost of a closing purchase
transaction exceeds the premium received when the option was sold), and the
deferred credit related to such option will be eliminated. If a call option is
exercised, the Portfolio will realize a gain or loss from the sale of the
underlying security and the proceeds of the sale will be increased by the
premium originally received. The writing of covered call options may be deemed
to involve the pledge of the securities against which the option is being
written. Securities against which call options are written will be segregated on
the books of the custodian for the Portfolio.
 
     A Portfolio may purchase call and put options on any securities in which it
may invest. A Portfolio would normally purchase a call option in anticipation of
an increase in the market value of such securities. The purchase of a call
option would entitle the Portfolio, in exchange for the premium paid, to
purchase a security at a specified price during the option period. A Portfolio
would ordinarily have a gain if the value of the securities increased above the
exercise price sufficiently to cover the premium and would have a loss if the
value of the securities remained at or below the exercise price during the
option period.
 
     A Portfolio would normally purchase put options in anticipation of a
decline in the market value of securities in its portfolio ("protective puts")
or securities of the type in which it is permitted to invest. The purchase of a
put option would entitle a Portfolio, in exchange for the premium paid, to sell
a security, which may or may not be held in the Portfolio's portfolio, at a
specified price during the option period. The purchase of protective puts is
designed merely to offset or hedge against a decline in the market value of the
Portfolio's portfolio securities. Put options also may be purchased by a
Portfolio for the purpose of affirmatively benefiting from a decline in the
price of securities which the Portfolio does not own. A Portfolio would
ordinarily recognize a gain if the value of the securities decreased below the
exercise price sufficiently to cover the premium and would recognize a loss if
the value of the securities remained at or above the exercise price. Gains and
losses on the purchase of protective put options would tend to be offset by
countervailing changes in the value of underlying portfolio securities.
 
     The Portfolios have adopted certain other nonfundamental policies
concerning option transactions which are discussed below. A Portfolio's
activities in options may also be restricted by the requirements of the Internal
Revenue Code of 1986, as amended (the "Code"), for qualification as a regulated
investment company.
 
     The hours of trading for options on securities may not conform to the hours
during which the underlying securities are traded. To the extent that the option
markets close before the markets for the underlying securities, significant
price and rate movements can take place in the underlying securities markets
that cannot be reflected in the option markets. It is impossible to predict the
volume of trading that may exist in such options, and there can be no assurance
that viable exchange markets will develop or continue.
 
     The Portfolios may engage in over-the-counter options transactions with
broker-dealers who make markets in these options. At present, approximately ten
broker-dealers, including several of the largest primary dealers in U.S.
Government securities, make these markets. The ability to terminate
over-the-counter option positions is more limited than with exchange-traded
option positions because the predominant market is the issuing broker rather
than an exchange, and may involve the risk that broker-dealers participating in
such transactions will not fulfill their obligations. To reduce this risk, the
Portfolios will purchase such options only from broker-dealers who are primary
government securities dealers recognized by the Federal Reserve Bank of New York
and who agree to (and are expected to be capable of) entering into closing
transactions, although there can be no guarantee that any such option will be
liquidated at a favorable price prior to expiration. The
 
                                       16
<PAGE>   58
 
Advisers will monitor the creditworthiness of dealers with whom a Portfolio
enters into such options transactions under the general supervision of the
Portfolios' Trustees.
 
OPTIONS ON SECURITIES INDICES -- PORTFOLIOS OTHER THAN MONEY MARKET PORTFOLIO
 
     In addition to options on securities, the Portfolios may also purchase and
write (sell) call and put options on securities indices. Such options give the
holder the right to receive a cash settlement during the term of the option
based upon the difference between the exercise price and the value of the index.
Such options will be used for the purposes described above under "Options on
Securities."
 
     Options on securities indices entail risks in addition to the risks of
options on securities. The absence of a liquid secondary market to close out
options positions on securities indices is more likely to occur, although the
Portfolios generally will only purchase or write such an option if the Advisers
believe the option can be closed out.
 
     Use of options on securities indices also entails the risk that trading in
such options may be interrupted if trading in certain securities included in the
index is interrupted. The Portfolios will not purchase such options unless the
Advisers believe the market is sufficiently developed such that the risk of
trading in such options is no greater than the risk of trading in options on
securities.
 
     Price movements in the Portfolios' securities may not correlate precisely
with movements in the level of an index and, therefore, the use of options on
indices cannot serve as a complete hedge. Because options on securities indices
require settlement in cash, the Advisers may be forced to liquidate portfolio
securities to meet settlement obligations.
 
SHORT SALES "AGAINST THE BOX" -- PORTFOLIOS OTHER THAN MONEY MARKET PORTFOLIO
 
     In a short sale, a fund sells a borrowed security and has a corresponding
obligation to the lender to return the identical security. A Portfolio may
engage in short sales only if at the time of the short sale it owns or has the
right to obtain, at no additional cost, an equal amount of the security being
sold short. This investment technique is known as a short sale "against the
box".
 
     In a short sale, the seller does not immediately deliver the securities
sold and is said to have a short position in those securities until delivery
occurs. If a Portfolio engages in a short sale, the collateral for the short
position will be maintained by its custodian or qualified sub-custodian. While
the short sale is open, a Portfolio maintains in a segregated account an amount
of securities equal in kind and amount to the securities sold short or
securities convertible into or exchangeable for such equivalent securities.
These securities constitute the Portfolio's long position.
 
     The Portfolios will not engage in short sales against the box for
investment purposes. A Portfolio may, however, make a short sale as a hedge,
when it believes that the price of a security may decline, causing a decline in
the value of a security (or a security convertible or exchangeable for such
security), or when a Portfolio wants to sell the security at an attractive
current price, but also wishes to defer recognition of gain or loss for federal
income tax purposes or for purposes of satisfying certain tests applicable to
regulated investment companies under the Code. In such case, any future losses
in a Portfolio's long position should be reduced by a gain in the short
position. Conversely, any gain in the long position should be reduced by a loss
in the short position. The extent to which such gains or losses are reduced
depends upon the amount of the security sold short relative to the amount a
Portfolio owns. There are certain additional transaction costs associated with
short sales against the box, but the Portfolios endeavor to offset these costs
with the income from the investment of the cash proceeds of short sales.
 
     As a nonfundamental operating policy, the Advisers do not expect that more
than 40% of a Portfolio's total assets would be involved in short sales against
the box. The Advisers do not currently intend to engage in such sales.

CERTAIN OTHER OBLIGATIONS
 
     In order to allow for investments in new instruments that may be created in
the future, upon the Trust supplementing the Prospectus, a Portfolio or
Portfolios may invest in obligations other than those listed previously,
provided such investments are consistent with a Fund's and its corresponding
Portfolio's investment objective, policies and restrictions.
 
RATING SERVICES
 
     The ratings of rating services represent their opinions as to the quality
of the securities that they undertake to rate. It should be emphasized, however,
that ratings are relative and subjective and are not absolute standards of
quality. Although these ratings are an initial criterion for selection of
portfolio investments, the Advisers also make their own evaluations of these
securities, subject to review by the Board of Trustees. After purchase by a
Portfolio, an obligation may cease to be rated or its rating may be reduced
below the minimum required for purchase by the Portfolio. Neither event would
require a Portfolio to dispose of the obligation, but the Advisers will consider
such an event in their determination of whether a Portfolio should continue to
hold the obligation. A description of the ratings used herein and in the Funds'
Prospectus is set forth in the Appendix to this Statement of Additional
Information.
 
     Except as stated otherwise, all investment policies and restrictions
described herein are nonfundamental, and may be changed without prior
shareholder approval.
 
                            INVESTMENT RESTRICTIONS
 
     The following investment restrictions are "fundamental policies" of each
Fund and each Portfolio and may not be changed with respect to the Fund or the
Portfolio without the approval of a "majority of the outstanding voting
securities" of the Fund or the Portfolio, as the case may be. "Majority of the
outstanding voting securities" under the 1940 Act and as used in this Statement
of Additional Information and the Prospectus means, with respect to the Fund (or
the Portfolio), the lesser of (i) 67% or more of the outstanding voting
securities of the Fund (or of the total beneficial interests of the Portfolio)
present at a meeting, if the holders of more than 50% of the outstanding voting
securities of the Fund (or of the total beneficial interests of the Portfolio)
are present or represented by proxy, or (ii) more than 50% of the outstanding
voting securities of the Fund (or of the total beneficial interests of the
Portfolio). Whenever the Trust is requested to vote on a fundamental policy of a
Portfolio, the Trust will hold a meeting of the corresponding Fund's
shareholders and will cast its vote as instructed by that Fund's shareholders.
If a percentage or a rating restriction on investment or utilization of assets
is adhered to at the time an investment is made or assets are so utilized, a
later change in such percentage resulting from changes in a Portfolio's total
assets or the value of a Portfolio's securities, or a later change in the rating
of a portfolio security, will not be considered a violation of the relevant
policy.
 
     As a matter of fundamental policy, no Portfolio (or Fund) may (except that
no investment restriction of a Fund shall prevent a Fund from investing all of
its assets in an open-end investment company with substantially the same
investment objectives as that Fund):
 
          (1) borrow money or mortgage or hypothecate assets of the Portfolio
     (Fund), except that in an amount not to exceed 1/3 of the current value of
     the Portfolio's (Fund's) assets (including such borrowing) less liabilities
     (not including such borrowing), it may borrow money and enter into reverse
     repurchase agreements, and except that it may pledge, mortgage or
     hypothecate not more than 1/3 of such assets to secure such borrowings or
     reverse repurchase agreements, provided that collateral arrangements with
     respect to options and futures, including deposits of initial deposit and
     variation margin, are not considered a pledge of assets for purposes of
     this restriction and except that assets may be pledged to secure letters of
     credit solely for the purpose of participating in a captive insurance
     company sponsored by the Investment Company Institute;
 
          (2) underwrite securities issued by other persons except insofar as
     the Portfolio Series or the Portfolio (the Trust or the Fund) may
     technically be deemed an underwriter under the 1933 Act in selling a
     portfolio security;
 
                                       18
<PAGE>   60
 
          (3) make loans to other persons except (a) through the lending of the
     Portfolio's (Fund's) portfolio securities and provided that any such loans
     not exceed 30% of the Portfolio's (Fund's) total assets (taken at market
     value), (b) through the use of repurchase agreements or the purchase of
     short-term obligations or (c) by purchasing debt securities of types
     distributed publicly or privately;
 
          (4) purchase or sell real estate (including limited partnership
     interests but excluding securities secured by real estate or interests
     therein), interests in oil, gas or mineral leases, commodities or commodity
     contracts (except futures and option contracts) in the ordinary course of
     business (the Portfolio Series (Trust) may hold and sell, for the
     Portfolio's (Fund's) portfolio, real estate acquired as a result of the
     Portfolio's (Fund's) ownership of securities);
 
          (5) concentrate its investments in any particular industry (excluding
     U.S. Government securities), but if it is deemed appropriate for the
     achievement of the Portfolio's (Fund's) investment objective(s), up to 25%
     of its total assets may be invested in any one industry (except that the
     Money Market Portfolio (Money Market Fund) reserves the freedom of action
     to concentrate 25% or more of its assets in obligations of domestic
     branches of domestic banks);
 
          (6) issue any senior security (as that term is defined in the 1940
     Act) if such issuance is specifically prohibited by the 1940 Act or the
     rules and regulations promulgated thereunder, provided that collateral
     arrangements with respect to options and futures, including deposits of
     initial deposit and variation margin, are not considered to be the issuance
     of a senior security for purposes of this restriction.
 
     State and Federal Restrictions.  In order to comply with certain state and
federal statutes and policies each Portfolio (or the Trust, on behalf of each
Fund) will not as a matter of operating policy (except that no operating policy
shall prevent a Fund from investing all of its assets in an open-end investment
company with substantially the same investment objective as that Fund):
 
          (i)   borrow money for any purpose in excess of 10% of the Portfolio's
                (Fund's) total assets (taken at cost), except that the Portfolio
                (Fund) may borrow for temporary or emergency purposes up to 1/3
                of its assets;
 
          (ii)  pledge, mortgage or hypothecate for any purpose in excess of 10%
                of the Portfolio's (Fund's) net assets (taken at market value),
                provided that collateral arrangements with respect to options
                and futures, including deposits of initial deposit and variation
                margin, reverse repurchase agreements, when-issued securities
                and other similar investment techniques are not considered a
                pledge of assets for purposes of this restriction;
 
          (iii)  purchase any security or evidence of interest therein on
                 margin, except that such short-term credit as may be necessary
                 for the clearance of purchases and sales of securities may be
                 obtained and except that deposits of initial deposit and
                 variation margin may be made in connection with the purchase,
                 ownership, holding or sale of futures;
 
          (iv) invest for the purpose of exercising control or management;
 
          (v)   purchase securities issued by any other investment company
                except by purchase in the open market where no commission or
                profit to a sponsor or dealer results from such purchase other
                than the customary broker's commission, or except when such
                purchase, though not made in the open market, is part of a plan
                of merger or consolidation; provided, however, that securities
                of any investment company will not be purchased for the
                Portfolio (Fund) if such purchase at the time thereof would
                cause (a) more than 10% of the Portfolio's (Fund's) total assets
                (taken at the greater of cost or market value) to be invested in
                the securities of such issuers; (b) more that 5% of the
                Portfolio's (Fund's) total assets (taken at the greater of cost
                or market value) to be invested in any one investment company;
                or (c) more than 3% of the outstanding voting securities of any
                such issuer to be held for the Portfolio (Fund); and provided
                further that the Portfolio (Fund) may not purchase any security
                from any open-end investment company;
 
                                       19
<PAGE>   61
 
          (vi)  purchase securities of any issuer if such purchase at the time
                thereof would cause the Portfolio (Fund) to hold more than 10%
                of any class of securities of such issuer, for which purposes
                all indebtedness of an issuer shall be deemed a single class and
                all preferred stock of an issuer shall be deemed a single class,
                except that futures or option contracts shall not be subject to
                this restriction;
 
          (vii)  purchase or retain in the Portfolio's (Fund's) portfolio any
                 securities issued by an issuer any of whose officers,
                 directors, trustees or security holders is an officer or
                 Trustee of the Portfolio (Trust), or is an officer or partner
                 of the Adviser or Subadviser, if after the purchase of the
                 securities of such issuer for the Portfolio (Fund) one or more
                 of such persons owns beneficially more than 1/2 of 1% of the
                 shares or securities, or both, all taken at market value, of
                 such issuer, and such persons owning more than 1/2 of 1% of
                 such shares or securities together own beneficially more than
                 5% of such shares or securities, or both, all taken at market
                 value;
 
          (viii) invest more than 5% of the Portfolio's (Fund's) net assets in
                 warrants or rights (valued at the lower of cost or market), but
                 not more than 2% of the Portfolio's (Fund's) net assets may be
                 invested in warrants not listed on the New York Stock Exchange
                 or the American Stock Exchange; and
 
          (ix)  make short sales of securities or maintain a short position
                (excluding short sales if the Portfolio (Fund) owns an equal
                amount of such securities or securities convertible into or
                exchangeable for, without payment of any further consideration,
                securities of equivalent kind and amount) if such short sales
                represent more than 25% of the Portfolio's (Fund's) net assets
                (taken at market value); provided, however, that the value of
                the Portfolio's (Fund's) short sales of securities (excluding
                U.S. Government securities) of any one issuer may not be greater
                than 2% of the value (taken at market value) of the Portfolio's
                (Fund's) net assets or more than 2% of the securities of any
                class of any issuer.
 
          (x)   enter into repurchase agreements providing for settlement in
                more than seven days after notice or purchase securities which
                are not readily marketable (which securities would include
                participation interests that are not subject to the demand
                feature described in the Fund's then-current Prospectus and
                floating and variable rate demand obligations as to which no
                secondary market exists and the Portfolio cannot exercise the
                demand feature described in the Fund's then-current Prospectus
                on not more than seven days' notice), if, in the aggregate, more
                than 15% (10% in the case of the Money Market Portfolio(Fund))
                of its net assets would be so invested. A Portfolio (Fund) may
                not invest in TDs maturing in more than seven days.
 
     Policies (i) through (x) may be changed by the Board of Trustees of the
Portfolio or the Trust.
 
                PORTFOLIO TRANSACTIONS AND BROKERAGE COMMISSIONS
 
     Except as may be required to ensure satisfaction of certain tests
applicable to regulated investment companies under the Code, portfolio changes
are made without regard to the length of time a security has been held, or
whether a sale would result in the recognition of a profit or loss. Therefore,
the rate of portfolio turnover is not a limiting factor when changes are
appropriate. Portfolio trading is engaged in for a Portfolio if the Advisers
believe that a transaction net of costs (including custodian charges) will help
achieve the Portfolio's investment objective.
 
     A Portfolio's purchase and sales of securities may be principal
transactions, that is, securities may be purchased directly from the issuer or
from an underwriter or market maker for the securities. There usually are no
brokerage commissions paid for such purchases and, therefore, the Portfolios do
not anticipate paying brokerage commissions in such transactions. Any
transactions for which a Portfolio pays a brokerage commission will be effected
at the best price and execution available. Purchases from underwriters of
securities include a commission or concession paid by the issuer to the
underwriter, and purchases from dealers serving as market makers include the
spread between the bid and the asked price.
 
                                       20
<PAGE>   62
 
     Allocations of transactions, including their frequency, to various dealers
is determined by the Subadvisers in their best judgement and in a manner deemed
to be in the best interest of the investors in a Portfolio rather than by any
formula. The primary consideration is prompt execution of orders in an effective
manner at the most favorable price.
 
     Investment decisions for a Portfolio will be made independently from those
for any other account or investment company that is or may in the future become
managed by the Advisers or their affiliates. If, however, a Portfolio and other
investment companies or accounts managed by the Subadvisers are
contemporaneously engaged in the purchase or sale of the same security, the
transactions may be averaged as to price and allocated equitably to each
account. In some cases, this policy might adversely affect the price paid or
received by a Portfolio or the size of the position obtainable for the
Portfolio. In addition, when purchases or sales of the same security for a
Portfolio and for other investment companies managed by the Subadvisers occur
contemporaneously, the purchase or sale orders may be aggregated in order to
obtain any price advantages available to large denomination purchases or sales.
Furthermore, in certain circumstances affiliates of the Subadvisers whose
investment portfolios are managed internally, rather than by the Subadvisers,
might seek to purchase or sell the same type of investments at the same time as
a Portfolio. Such an event might also adversely affect that Portfolio.
 
                            PERFORMANCE INFORMATION
 
MONEY MARKET FUND
 
     For the Money Market Fund, yield is computed in accordance with a
standardized method which involves determining the net change in the value of a
hypothetical pre-existing Money Market Fund account having a balance of one
share at the beginning of a seven calendar day period for which yield is to be
quoted, dividing the net change by the value of the account at the beginning of
the period to obtain the base period return, and annualizing the results (i.e.,
multiplying the base period return by 365/7). The net change in the value of the
account reflects the value of additional shares purchased with dividends
declared on the original share and any such additional shares and fees that may
be charged to shareholder accounts, in proportion to the length of the base
period and the Money Market Fund's average account size, but does not include
realized gains and losses or unrealized appreciation and depreciation. Effective
annualized yield is computed by adding 1 to the base period return (calculated
as described above), raising that sum to a power equal to 365 divided by 7, and
subtracting 1 from the result.
 
     Yields will fluctuate and are not necessarily representative of future
results. The investor should remember that yield is a function of the type and
quality of the instruments held by the Money Market Portfolio, portfolio
maturity and operating expenses. An investor's principal in the Money Market
Fund is not guaranteed. See "Determination of Net Asset Value" for a discussion
of the manner in which the Money Market Fund's price per share is determined.
 
     From time to time, the Money Market Fund in its advertising and sales
literature may refer to the growth of assets managed or administered by the

ALL FUNDS
 
                        STANDARD PERFORMANCE INFORMATION
 
     From time to time, quotations of a Fund's performance may be included in
advertisements, sales literature or shareholder reports. These performance
figures are calculated in the following manner for each Fund:
 
          TOTAL RETURN: The Fund's total return will be calculated for certain
     periods by determining the average annual compounded rates of return over
     those periods that would cause an investment of $1,000 (with all
     distributions reinvested) to reach the value of that investment at the end
     of the periods. The Fund may also calculate (i) a total return assuming an
     initial account value of $1,000 and/or (ii) total rates of return which
     represent aggregate performance over a period of year-by-year performance.
 
          YIELD: The Fund's yield quotation will be based on the annualized net
     investment income per share of the Fund over a 30-day period. The current
     yield for the Fund is calculated by dividing the net investment income per
     share of the Fund earned during the period by the net asset value per share
     of the Fund on the last day of that period. The resulting figure is then
     annualized. Net investment income per share is determined by dividing (i)
     the dividends and interest earned during the period, minus accrued expenses
     for the period, by (ii) the average number of Fund shares entitled to
     receive dividends during the period multiplied by the net asset value per
     share on the last day of the period.
 
     Total returns calculated for any of the Funds for any period which includes
a period prior to the reorganization date will reflect the performance of the
corresponding Pooled Separate Account. The reorganization date is the date on
which the corresponding Pooled Separate Account of The Mutual Life Insurance
Company of New York ("MONY") set forth below contributed all of its assets to
the corresponding Portfolio of Diversified Investors Portfolios in which the
corresponding Fund invests its assets:

</TABLE>
 
     Such total returns calculated for each of the Funds will reflect the
performance of the corresponding Pooled Separate Account only from the date that
such corresponding Pooled Separate Account adopted investment objectives,
policies and practices substantially similar to those of the corresponding
Portfolio of Diversified Investors Portfolios invested in by the Fund. All total
return percentages for such periods will reflect the historical rates of return
of the corresponding Pooled Separate Account for such period adjusted to assume
that all charges, expenses and fees of the applicable Fund which are presently
in effect were deducted during such period. The corresponding Pooled Separate
Accounts were not registered under the Investment Company Act of 1940 and,
therefore, were not subject to certain investment restrictions imposed by that
Act. If the corresponding Pooled Separate Accounts had been registered under
that Act, investment performance might have been adversely affected.

     The average annual total returns for the High-Yield Bond Fund reflect
annualized returns for all private accounts and collective investment vehicles
managed by Delaware Investment Advisers during the periods indicated with
investment objectives, policies and restrictions substantially similar to the
High-Yield Bond Fund, and which have been managed as the High-Yield Bond Fund is
expected to be managed. These returns are adjusted to assume that all charges,
expenses and fees of the High-Yield Bond which are presently in effect were
deducted during such periods. At December 31, 1995, the annualized total returns
for the High-Yield Bond Fund were as follows: Since Inception --       %; 1
Year --       %; 3 Years --       %; 5 Years --       %; and 10
Years --       %.
    
 
   
     The average annual total returns for the Equity Value Fund reflect
annualized returns for all private accounts and collective investment vehicles
managed by Ark Asset Management Co., Inc. during the periods indicated with
investment objectives, policies and restrictions substantially similar to the
Equity Value Fund, and which have been managed as the Equity Value Fund is
expected to be managed. These returns are adjusted to assume that all charges,
expenses and fees of the Equity Value Fund which are presently in effect were
deducted during such periods. At December 31, 1995, the annualized total returns
for the High-Yield Bond Fund were as follows: Since Inception --       %; 1
Year --       %; 3 Years --       %; 5 Years --       %; and 10
Years --       %.
    
 
   
     The average annual total returns for the Aggressive Equity Fund reflect
annualized returns for all private accounts and collective investment vehicles
managed by McKinley Capital Management, Inc. during the periods indicated with
investment objectives, policies and restrictions substantially similar to the
Aggressive Equity Fund, and which have been managed as the Aggressive Equity
Fund is expected to be managed. These returns are adjusted to assume that all
charges, expenses and fees of the Aggressive Equity Fund which are presently in
effect were deducted during such periods. At December 31, 1995, the annualized
total returns for the High-Yield Bond Fund were as follows: Since
Inception --       %; 1 Year --       %; 3 Years --       %; 5 Years --       %;
and 10 Years --       %.
    
 
     Effective November 14, 1995, Putnam Advisory Company, Inc. ("Putnam")
became the subadvisor to the Growth & Income Fund. The average annual total
returns at June 30, 1995 for all private accounts and collective investment
vehicles managed by Putnam with investment objectives, policies and restrictions
substantially similar to the Growth & Income Fund, adjusted to assume that all
charges, expenses and fees of the Growth & Income Fund presently in effect were
deducted, are as follows: Since Inception -- %; 1 Year --       %; 3
Years --       %; and 5 Years --       %.
 
     Any yield or total return quotation provided for the Fund should not be
considered as representative of the performance of the Fund in the future since
the net asset value of shares of the Fund will vary based not only on the type,
quality and maturities of the securities held in the Portfolio, but also on
changes in the current value of such securities and on changes in the expenses
of the Fund and the Portfolio. These factors
 
                                       23
<PAGE>   65
 
and possible differences in the methods used to calculate yields and total
return should be considered when comparing the yield and total return of the
Fund to yields and total rates of return published for other investment
companies or other investment vehicles. Total return reflects the performance of
both principal and income.
 
                         COMPARISON OF FUND PERFORMANCE
 
     Comparison of the quoted non-standardized performance of various
investments is valid only if performance is calculated in the same manner. Since
there are different methods of calculating performance, investors should
consider the effect of the methods used to calculate performance when comparing
performance of a Fund with performance quoted with respect to other investment
companies or types of investments.
 
     In connection with communicating its performance to current or prospective
shareholders, a Fund also may compare these figures to the performance of other
mutual funds tracked by mutual fund rating services or to unmanaged indices
which may assume reinvestment of dividends but generally do not reflect
deductions for administrative and management costs. A Portfolio may invest in
some instruments not eligible for inclusion in such an index, and may be
prohibited from investing in some instruments included in this index.

           DETERMINATION OF NET ASSET VALUE; VALUATION OF SECURITIES
 
     The Trust determines the net asset value of the shares of each Fund each
day that the Advisers of the corresponding Portfolio are open for business. (As
a result, a Fund will normally determine its net asset value every weekday
except for the following holidays: New Year's Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas.) This
daily determination of net asset value is made as of the close of regular
trading on the New York Stock Exchange, currently 4:00 p.m., New York time, by
dividing the total assets of a Fund less all of its liabilities, by the total
number of shares of a Fund outstanding at the time the determination is made.
Purchases and redemptions will be effected at the time of determination of net
asset value next following the receipt of any purchase or redemption order
deemed to be in good order. (See "Purchases and Redemptions of Shares" in the
Prospectus.)
 
     Trading in securities on most non-U.S. exchanges and over-the-counter
markets is normally completed before the close of regular trading on the New
York Stock Exchange and may also take place on days on which the New York Stock
Exchange is closed. If events materially affecting the value of non-U.S.
securities occur between the time when the exchange on which they are traded
closes and the time when a Fund's net asset value is calculated, such securities
will be valued at fair value in accordance with procedures established by and
under the general supervision of the Board of Trustees of the Trust.
 
     Equity securities are valued at the last sale price on the exchange on
which they are primarily traded or at the ask price on the NASDAQ system for
unlisted national market issues, or at the last quoted bid price for securities
in which there were no sales during the day or for unlisted securities not
reported on the NASDAQ system. Bonds and other fixed income securities (other
than short-term obligations, but including listed issues) are valued on the
basis of valuations furnished by a pricing service, the use of which has been
approved by the Board of Trustees. In making such valuations, the pricing
service utilizes both dealer-supplied valuations and electronic data processing
techniques that take into account appropriate factors such as institutional-size
trading in similar groups of securities, yield, quality, coupon rate, maturity,
type of issue, trading characteristics and other market data, without exclusive
reliance upon quoted prices or exchange or over-the-counter prices, since such
valuations are believed to reflect more accurately the fair value of such
securities. Short-term obligations which mature in 60 days or less are valued at
amortized cost, which approximates fair value as determined by the Board of
Trustees. Futures and option contracts that are traded
 
                                       25
<PAGE>   67
 
on commodities or securities exchanges are normally valued at the settlement
price on the exchange on which they are traded. Portfolio securities (other than
short-term obligations) for which there are no such quotations or valuations are
valued at fair value as determined in good faith by or at the direction of the
Board of Trustees.
 
     Interest income on long-term obligations is determined on the basis of
interest accrued plus amortization of discount (generally, the difference
between issue price and stated redemption price at maturity) and premiums
(generally, the excess of purchase price over stated redemption price at
maturity). Interest income on short-term obligations is determined on the basis
of interest and discount accrued less amortization of premium.
 
     Any assets or liabilities initially denominated in terms of foreign
currencies are translated into U.S. dollars at the official exchange rate or,
alternatively, at the mean of the current bid and asked prices of such
currencies against the U.S. dollar last quoted by a major bank that is a regular
participant in the foreign exchange market or on the basis of a pricing service
that takes into account the quotes provided by a number of such major banks. If
neither of these alternatives is available or both are deemed not to provide a
suitable methodology for converting a foreign currency into U.S. dollars, the
Board of Trustees, in good faith, will establish a conversion rate for such
currency.
 
     A determination of value used in calculating net asset value must be a fair
value determination made in good faith utilizing procedures approved by the
Portfolio Series' Board of Trustees. While no single standard for determining
fair value exists, as a general rule, the current fair value of a security would
appear to be the amount which a Portfolio could expect to receive upon its
current sale. Some, but not necessarily all, of the general factors which may be
considered in determining fair value include: (i) the fundamental analytical
data relating to the investment; (ii) the nature and duration of restrictions on
disposition of the securities; and (iii) an evaluation of the forces which
influence the market in which these securities are purchased and sold. Without
limiting or including all of the specific factors which may be considered in
determining fair value, some of the specific factors include: type of security,
financial statements of the issuer, cost at date of purchase, size of holding,
discount from market value, value of unrestricted securities of the same class
at the time of purchase, special reports prepared by analysts, information as to
any transactions or offers with respect to the security, existence of merger
proposals or tender offers affecting the securities, price and extent of public
trading in similar securities of the issuer or comparable companies, and other
relevant matters.
 
     Each investor in each Portfolio, including the corresponding Fund, may add
to or reduce its investment in the Portfolio on each day that the Adviser and
the Subadviser of the Portfolio are open for business. As of 4:00 p.m. (New York
time) on each such day, the value of each investor's interest in a Portfolio
will be determined by multiplying the net asset value of the Portfolio by the
percentage representing that investor's share of the aggregate beneficial
interests in the Portfolio. Any additions or reductions which are to be effected
on that day will then be effected. The investor's percentage of the aggregate
beneficial interests in the Portfolio will then be recomputed as the percentage
equal to the fraction (i) the numerator of which is the value of such investor's
investment in the Portfolio as of 4:00 p.m. on such day plus or minus, as the
case may be, the amount of net additions to or reductions in the investor's
investment in the Portfolio effected on such day, and (ii) the denominator of
which is the aggregate net asset value of the Portfolio as of 4:00 p.m. on such
day plus or minus, as the case may be, the amount of the net additions to or
reductions in the aggregate investments in the Portfolio by all investors in the
Portfolio. The percentage so determined will then be applied to determine the
value of the investor's interest in a Portfolio as of 4:00 p.m. on the following
day the New York Stock Exchange is open for trading.

                          INVESTMENT ADVISORY SERVICES
 
     The Adviser manages the assets of each Portfolio pursuant to an Investment
Advisory Agreement (the "Advisory Agreement") with the Portfolio Series with
respect to that Portfolio and the investment policies described herein and in
the Prospectus for the corresponding Fund. Subject to such further policies as
the Portfolio Series's Board of Trustees may determine, the Adviser provides
general investment advice to each Portfolio. For its services under each
Advisory Agreement, Diversified receives from each Portfolio fees accrued daily
and paid monthly at an annual rate equal to the percentages specified in the
table below of the corresponding Portfolio's average daily net assets.
 
     For each Portfolio, the Adviser has entered into an Investment Subadvisory
Agreement (each a "Subadvisory Agreement") with each Subadviser.
 
     Each Advisory Agreement provides that the Adviser or a Subadviser, as the
case may be, may render services to others. Each agreement is terminable without
penalty on not more than 60 days' nor less than 30 days' written notice by a
Portfolio when authorized either by majority vote of the investors in the
Portfolio (with the vote of each being in proportion to the amount of its
investment) or by a vote of a majority of the Board of Trustees of the Portfolio
Series, or by the Adviser or a Subadviser on not more than 60 days' nor less
than 30 days' written notice, as the case may be, and will automatically
terminate in the event of its assignment. Each agreement provides that neither
the Adviser nor Subadviser nor their personnel shall be liable for any error of
judgment or mistake of law or for any loss arising out of any investment or for
any act or omission in the execution of security transactions for the
corresponding Portfolio, except for willful misfeasance, bad faith, gross
negligence or reckless disregard of its or their obligations and duties under
the Advisory Agreement and the Subadvisory Agreement, as the case may be.
 
     The Adviser's and Subadviser's fees are described in the Funds' Prospectus.
The Adviser, if required by applicable state law, shall reimburse a Fund or
waive all or part of its fees up to, but not exceeding, its investment advisory
fees from the corresponding Portfolio. Such reimbursement, if required, will be
equal to the combined aggregate annual expenses of the appropriate Fund and its
corresponding Portfolio which exceed that expense limitation with the lowest
threshold prescribed by any state in which such Fund is qualified for offer or
sale. Management of each of the Trust and the Portfolios has been advised that
the lowest such threshold currently in effect is 2 1/2% of net assets up to
$30,000,000, 2% of the next $70,000,000 of net assets and 1 1/2% of net assets
in excess of that amount.
 
     Diversified is an investment firm dedicated to meeting the complete needs
of retirement plan sponsors and participants from pre- through post-retirement.
Diversified provides flexible, high-quality services coupled with the employment
of independent investment managers in an innovative investment structure.
 
     Diversified services over $8 billion in retirement plan assets and has
offices in Boston, Charlotte, Chicago, Cincinnati, Dallas, Houston, New Orleans,
New York, Philadelphia, Portland and San Francisco. It maintains recordkeeping
for 300,000 participants and has 490 employees dedicated to retirement plan
investment and administration. Its employees average more than seven years of
retirement plan experience.
 
     As experts in customizing retirement solutions, Diversified offers
comprehensive programs of high-quality investments and administrative services
to defined benefit, defined contribution and not-for-profit pension plan
sponsors. Diversified forms a partnership with its clients to provide
exceptional plan design, participant communication programs, recordkeeping
services and technical guidance.
 
     Diversified's investment structure provides access to an array of
complementary investment alternatives representing the major asset classes along
the risk/reward spectrum. Subadvisers are selected from more than 2,000 highly
accomplished independent firms. Each subadviser's performance is carefully
monitored by Diversified taking into consideration fund performance in light of
investment objectives and policies and level of risk.
 
     Through a rigorous portfolio manager selection process which includes
researching each subadviser's asset class, track record, organizational
structure, management team, consistency of performance and assets under
management, five to ten subadvisers are chosen. Out of that group, Diversified
then carefully chooses
 
                                       30
<PAGE>   72
 
the three most qualified subadvisers based on performance evaluation, ownership
structure, personnel and philosophy to return for an on-site visit and a
quantitative and qualitative analysis by the investment committee. Out of those
three subadvisers, Diversified then hires the most qualified, independent
subadviser for each Portfolio, subject to approval by the Portfolio Series'
Board of Trustees including a majority of the Trustees who are not "interested
persons" of the Portfolio Series.
 
     Diversified brings comprehensive monitoring and control to the investment
management process. It seeks superior portfolio management and moves
purposefully in replacing managers when warranted. From a plan sponsor's
perspective, replacing a manager, and not the investment fund, is a key
advantage in avoiding the expense and difficulty of re-enrolling participants or
disrupting established plan administration. Replacing a Subadviser, however,
will necessitate a shareholder proxy solicitation which involves other expenses
to a Fund.
 
     Highly disciplined manager evaluation on both a quantitative and
qualitative basis, is an ongoing process. Diversified's Manager Monitoring Group
gathers and analyzes performance and Diversified's Investment Committee reviews
it. Performance attribution, risk/return ratios and purchase/sale assessments
are prepared monthly and, each quarter, a more comprehensive review is completed
which consists of manager visits, fundamental analysis and statistical analysis.
Extensive quarterly analysis is conducted to ensure that the investment fund is
being managed in line with the stated objectives. Semiannually, the Investment
Committee reviews the back-up manager selection, regression analysis and
universe comparisons.
 
     A number of "red flags" signal a more extensive and frequent manager
review. These flags consist of a return inconsistent with the investment
objective, changes in subadviser leadership, ownership or portfolio managers,
large changes in assets under management and changes in philosophy or
discipline. The immediate response to any red flag is to assess the potential
impact on the manager's ability to meet investment objectives. Diversified
monitors "back-up" additional independent managers for each investment so that,
should a manager change be warranted, the transition can be effected on a timely
basis.
 
                                 ADMINISTRATOR
 
     The Administrative Services Agreements between Diversified, as
Administrator, and each of the Portfolio Series and the Trust are described in
the Prospectus. Each agreement provides that Diversified may render services to
others as administrator. In addition, each agreement terminates automatically if
it is assigned and may be terminated without penalty, in the case of the
Portfolio Series, by majority vote of the Funds and of the other investors in
the Portfolio Series (with the vote of each being in proportion to the amount of
its investment) or, in the case of the Trust, by majority vote of the Trust's
shareholders, or by either party on not more than 60 days' nor less than 30
days' written notice. Each Administrative Services Agreement also provides that
neither Diversified nor its personnel shall be liable for any error of judgment
or mistake of law or for any act or omission in connection with any Fund or
Portfolio, except for willful misfeasance, bad faith or gross negligence in the
performance of its or their duties or by reason of reckless disregard of its or
their duties or obligations under said agreements.
 
                          CUSTODIAN AND TRANSFER AGENT
 
     Pursuant to the Administrative and Transfer Agency Services Agreement,
Diversified acts as transfer agent for each of the Funds (the "Transfer Agent").
The Transfer Agent maintains an account for each shareholder of a Fund, performs
other transfer agency functions, and acts as dividend disbursing agent for each
Fund.
 
     Pursuant to two Custodian Agreements, Investors Bank & Trust Company acts
as the custodian of each Fund's assets, i.e., each Fund's interest in its
corresponding Portfolio, and as the custodian of each Portfolio's assets (the
"Custodian"). The Custodian's responsibilities include safeguarding and
controlling the Portfolios' cash and securities, handling the receipt and
delivery of securities, determining income and collecting interest on the
Portfolios' investments, maintaining books of original entry for portfolio
accounting and other required books and accounts, and calculating the daily net
asset value of beneficial interests in each Portfolio. Securities held by the
Portfolios may be deposited into the Federal Reserve-Treasury Department Book
Entry System or
 
                                       31
<PAGE>   73
 
the Depository Trust Company and may be held by a subcustodian bank if such
arrangements are reviewed and approved by the Trustees of the Portfolio Series.
The Custodian does not determine the investment policies of the Portfolios or
decide which securities the Portfolios will buy or sell. A Portfolio may,
however, invest in securities of the Custodian and may deal with the Custodian
as principal in securities and foreign exchange transactions. For its services,
the Custodian will receive such compensation as may from time to time be agreed
upon by it and the Trust and the Portfolio Series.
 
                                    TAXATION
 
                             TAXATION OF THE FUNDS
 
     Each Fund intends to qualify as a regulated investment company ("RIC") for
federal income tax purposes by meeting all applicable requirements of Subchapter
M of the Code, including requirements as to the nature of the Fund's gross
income, the amount of Fund distributions and the composition and holding period
of the Fund's portfolio assets. Because each Fund intends to distribute all of
its net investment income and net realized capital gains to its shareholders in
accordance with the timing requirements imposed by the Code, it is expected that
no Fund will be required to pay any federal income or excise taxes, although
foreign-source income may be subject to foreign withholding taxes. If a Fund
should fail to qualify as a "regulated investment company" in any year, the Fund
will incur a regular corporate federal income tax upon its taxable income
(thereby reducing the return realized by Fund shareholders) and Fund
distributions would constitute ordinary corporate dividends when issued to the
Qualified Investors. However, such Investors would not, in that event, incur any
income tax liability on such distributions provided they remain exempt from
federal income tax.
 
     Under interpretations of the Internal Revenue Service (1) each Portfolio
will be treated for federal income tax purposes as a partnership which is not a
publicly traded partnership and (2) for purposes of determining whether a Fund
satisfies requirements of Subchapter M of the Code, the Fund, as an investor in
its corresponding Portfolio, will be deemed to own a proportionate share of that
Portfolio's assets and will be deemed to be entitled to the Portfolio's income
attributable to that share. The Portfolio Series has advised the Funds that it
intends to conduct the Portfolios' operations so as to enable investors,
including the Funds, to satisfy those requirements.
 
     As RICs, the Funds will not be subject to federal income tax on their
investment company taxable income and net capital gain (the excess of net
longterm capital gain over net short-term capital loss), if any, that it
distributes to its shareholders. Thus, each Fund intends to distribute to its
shareholders, at least annually, substantially all of its investment company
taxable income and net capital gain.
 
     Amounts not distributed on a timely basis in accordance with a calendar
year distribution requirement are subject to a nondeductible 4% excise tax. To
prevent imposition of the excise tax, each Fund must, and intends to, distribute
during each calendar year substantially all of its ordinary income for that year
and of its capital gain in excess of its capital losses for the one-year period
ending on October 31 of that year, plus any undistributed ordinary income and
capital gains from previous years. For this and other purposes, a distribution
will be treated as paid on December 31 if it is declared by a Fund in October,
November or December with a record date in such a month and paid by the Fund
during January of the following calendar year. Accordingly, those distributions
will be taxable to shareholders for the taxable year in which that December 31
falls.
 
     Each Fund is designed to meet the long-term investment needs of, and will
be available only to, certain individual and group retirement plans which,
subject to specific requirements, may qualify for tax-exempt status under the
Code. Each Fund has been designed and will be managed with the assumption that
all shareholders are such tax-qualified individual or group plans. Accordingly,
Fund shares are not appropriate investments for individuals or participants in
group plans which would be subject to tax liability upon the occurrence of
distributions from a Fund, including redemptions of shares and exchanges between
Funds. Potential shareholders should consult their tax advisors prior to
purchasing Fund shares to ensure that any such purchase will be carried out
through an appropriate individual or group retirement plan and will be
 
                                       32
<PAGE>   74
 
consistent with the terms and restrictions of such plan. Where applicable,
participants in group retirement plans should consult their plan administrator
for additional information about restrictions on investments and other terms of
an underlying plan.
 
                                 DISTRIBUTIONS
 
     Tax-qualified retirement plans which invest in any Fund generally will not
be subject to tax liability on either distributions from a Fund or redemptions
of shares of a Fund. Rather, participants are taxed when they take distributions
from the underlying plan in accordance with the rules under the Code governing
the taxation of such distributions. Qualified Investors otherwise generally
exempt from federal taxation of their income might nevertheless be taxed on
distributions of the Fund, and any gain realized on redemption of Fund shares,
where the Investor is subject to the unrelated business taxable income
provisions of the Code with respect to its investment in the Fund because, e.g.,
its acquisition of shares in the Fund was financed with debt.
 
     If, for any reason, a Qualified Investor is not exempt from income taxation
such Qualified Investor will be subject to tax on distributions received from
the Fund irrespective of the fact that such distributions are reinvested in
additional shares. Distributions to such Investors, other than of net capital
gains, will be taxable as ordinary income; distributions of net capital gains
would be taxable to such Investors as long-term capital gain without regard to
the length of time they have held in shares in the Fund. Certain dividends
declared in October, November or December of a calendar year and paid to a
Qualified Investor which is subject to tax on the distribution in January of the
succeeding calendar year are taxable to such Investor as if paid on December 31
of the year in which they were declared.
 
                                 SALE OF SHARES
 
     Any gain or loss realized by a shareholder subject to federal income tax
upon the sale or other disposition of shares of a Fund, or upon receipt of a
distribution in complete liquidation of a Fund, generally will be a capital gain
or loss that will be long-term or short-term depending upon the shareholder's
holding period for the shares. Any loss realized on a sale or exchange of a
Fund's shares by such a shareholder will be disallowed to the extent the shares
disposed of are replaced (including by shares acquired pursuant to reinvested
distribution) within a period of 61 days beginning 30 days before and ending 30
days after the disposition. In such a case, the basis of the shares acquired
will be adjusted to reflect the disallowed loss. Any loss realized by such a
shareholder on a disposition of a Fund's shares held for six months or less will
be treated as a long-term capital loss to the extent of any distributions of net
capital gain received by the shareholder with respect to such shares.
 
                              FOREIGN SHAREHOLDERS
 
     The tax consequences to a foreign shareholder of an investment in a Fund
may be different from those described herein. Foreign shareholders are advised
to consult their own tax advisers with respect to the particular tax
consequences to them of an investment in a Fund.
 
                        TAXATION OF THE PORTFOLIO SERIES
 
     The Portfolio Series, if treated for tax purposes as a partnership, would
not be subject to federal income taxation. Instead, a Fund would take into
account, in computing its federal income tax liability, its share of the
Portfolio Series's income, gains, losses, deductions, credits and tax preference
items, without regard to whether it has received any cash distributions from the
Portfolio Series.
 
     Withdrawals by a Fund from its corresponding Portfolio generally will not
result in such Fund recognizing any gain or loss for federal income tax
purposes, except that (1) gain will be recognized to the extent that any cash
distributed exceeds the basis of a Fund's interest in its Portfolio prior to the
distribution, (2) income or gain will be realized if the withdrawal is in
liquidation of a Fund's entire interest in the Portfolio Series and includes a
disproportionate share of any unrealized receivables held by the Portfolio
Series, and (3) loss will
 
                                       33
<PAGE>   75
 
be recognized if the distribution is in liquidation of that entire interest and
consists solely of cash and/or unrealized receivables. The basis of a Fund's
interest in the Portfolio Series generally equals the amount of cash and the
basis of any property that the Fund invests in its corresponding Portfolio,
increased by the Fund's share of income from that Portfolio and decreased by the
amount of any cash distributions and the basis of any property distributed from
its corresponding Portfolio.
 
                           FOREIGN WITHHOLDING TAXES
 
     Income received by a Portfolio from sources within foreign countries may be
subject to withholding and other taxes imposed by such countries; it is not
expected that the Portfolios or the Funds will be able to "pass through" to the
Fund shareholders subject to tax any foreign tax credits with respect to these
taxes.
 
     Tax conventions between certain countries and the United States may reduce
or eliminate such taxes. It is impossible to determine the effective rate of
foreign tax in advance since the amount of assets to be invested in various
countries will vary.
 
                               HEDGING STRATEGIES
 
     The use of hedging strategies, such as a Portfolio's entry into interest
rate futures contracts and purchasing options thereon, involves complex rules
that will determine for income tax purposes the character and timing of
recognition of the income received in connection therewith.
 
     The Portfolios will limit their activities in options, futures contracts
and forward contracts to the extent necessary to allow the Funds to qualify as
RICs. As a result, however, a Portfolio may be forced to defer the closing out
of certain options and futures contracts beyond the time when it otherwise would
be advantageous to do so.
 
                                 OTHER TAXATION
 
     The Trust is organized as a Massachusetts business trust and, under current
law, neither the Trust nor any Fund is liable for any income or franchise tax in
the Commonwealth of Massachusetts, provided that each Fund continues to qualify
as a RIC for federal income tax purposes. The investment by each Fund in its
corresponding Portfolio does not cause a Fund to be liable for any income or
franchise tax in the State of New York.
 
     The Portfolio Series is organized as a New York trust. The Portfolio Series
is not subject to any income or franchise tax in the State of New York or, so
long as it is treated as a partnership (not taxable as a publicly traded
partnership) for federal income tax purposes, the Commonwealth of Massachusetts.
 
     Shareholders of the Funds may be subject to state and local taxes on a
Fund's distributions to them. Shareholders are advised to consult their own tax
advisers with respect to the particular tax consequences to them of an
investment in a Fund.
 
                               DISTRIBUTION PLAN
 
     The Trust has adopted a Distribution Plan (the "Distribution Plan") in
accordance with Rule 12b-1 under the 1940 Act after having concluded that there
is a reasonable likelihood that the Distribution Plan will benefit the Funds and
their shareholders. The Distribution Plan provides that the Distributor may
receive a fee from each Fund at an annual rate not to exceed 0.25% of that
Fund's average daily net assets in anticipation of, or as reimbursement for,
expenses incurred in connection with the sale of shares of the Fund, such as
advertising expenses and the expenses of printing (excluding typesetting) and
distributing Prospectuses and reports used for sales purposes, expenses of
preparing and printing of sales literature and other distribution-related
expenses.
 
                                       34
<PAGE>   76
 
     The Distribution Plan will continue in effect if such continuance is
specifically approved at least annually by a vote of both a majority of the
Trust's Trustees and a majority of the Trust's Trustees who are not "interested
persons" of the Trust and who have no direct or indirect financial interest in
the operation of the Distribution Plan or in any agreement related to such Plan
("Qualified Trustees"). The Distribution Plan requires that at least quarterly
the Trust and the Distributor shall provide to the Board of Trustees and the
Board of Trustees shall review a written report of the amounts expended (and the
purposes therefor) under the Distribution Plan. The Distribution Plan further
provides that the selection and nomination of the Trust's disinterested Trustees
shall be committed to the discretion of the Trust's disinterested Trustees then
in office. The Distribution Plan may be terminated with respect to a Fund at any
time by a vote of a majority of the Trust's Qualified Trustees or by vote of a
majority of the outstanding voting securities of that Fund. The Distribution
Plan may not be amended to increase materially the amount of permitted expenses
thereunder without the approval of a majority of the outstanding voting
securities of the Fund and may not be materially amended in any case without a
vote of the majority of both the Trust's Trustees and the Trust's Qualified
Trustees. The Distributor will preserve copies of any plan, agreement or report
made pursuant to the Distribution Plan for a period of not less than six years
from the date of the Distribution Plan, and for the first two years the
Distributor will preserve such copies in an easily accessible place.
 
     As contemplated by the Distribution Plan, Diversified Investors Securities
Corp. acts as the agent of the Funds in connection with the offering of shares
of the Funds pursuant to a Distribution Agreement (the "Distribution
Agreement"). After the Prospectuses and periodic reports have been prepared, set
in type and mailed to existing shareholders, the Distributor pays for the
printing and distribution of copies of the Prospectuses and periodic reports
which are used in connection with the offering of shares of the Funds to
prospective investors. The Prospectus contains a description of fees payable to
the Distributor under the Distribution Agreement.
 
                            INDEPENDENT ACCOUNTANTS
 
     Coopers & Lybrand L.L.P. serves as the Funds' and the Portfolios'
independent accountants providing audit and accounting services including (i)
audit of the annual financial statements, (ii) assistance and consultation with
respect to the preparation of filings with the SEC and (iii) preparation of
annual income tax returns.
 
                     DESCRIPTION OF THE TRUST; FUND SHARES
 
   
     The Trust is a Massachusetts business trust established under a Declaration
of Trust dated as of April 23, 1993. Its authorized capital consists of an
unlimited number of shares of beneficial interest of $0.00001 par value which
may be issued in separate series. Currently, the Trust has thirteen active
series, although additional series may be established from time to time. If
additional series are established, each share of a series will represent an
equal proportionate interest in that series with each other share of the series.
    
 
     The assets of the Trust received for the issue or sale of the shares of
each series and all income, earnings, profits and proceeds thereof, subject only
to the rights of creditors, are specifically allocated to such series and
constitute the underlying assets of such series. The underlying assets of each
series are segregated on the books of account, and are to be charged with the
liabilities in respect to such series and with such a share of the general
liabilities of the Trust. Expenses with respect to any two or more series are to
be allocated in proportion to the asset value of the respective series except
where allocations of direct expenses can otherwise be fairly made. The officers
of the Trust, subject to the general supervision of the Trustees, have the power
to determine which liabilities are allocable to a given series, or which are
general or allocable to two or more series. In the event of the dissolution or
liquidation of the Trust or any series, the holders of the shares of any series
are entitled to receive as a class the value of the underlying assets of such
shares available for distribution to shareholders.
 
     Shares of the Trust entitle their holder to one vote per share; however,
separate votes are taken by each series on matters affecting an individual
series. For example, a change in investment policy for a series would be voted
upon only by shareholders of the series involved.
 
                                       35
<PAGE>   77
 
     The Declaration of Trust provides that obligations of the Trust are not
binding upon the Trustees individually but only upon the property of the Trust,
that the Trustees and officers will not be liable for errors of judgment or
mistakes of fact or law, and that the Trust will indemnify its Trustees and
officers against liabilities and expenses incurred in connection with litigation
in which they may be involved because of their offices with the Trust unless, as
to liability to the Trust or its shareholders, it is finally adjudicated that
they engaged in willful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in their offices, or unless with respect to any
other matter it is finally adjudicated that they did not act in good faith in
the reasonable belief that their actions were in the best interests of the
Trust. In the case of settlement, such indemnification will not be provided
unless it has been determined by a court or other body approving the settlement
or other disposition, or by a reasonable determination, based upon a review of
readily available facts, by vote of a majority of disinterested Trustees or in a
written opinion of independent counsel, that such officers or Trustees have not
engaged in willful misfeasance, bad faith, gross negligence or reckless
disregard of their duties.
 
     Under Massachusetts law, shareholders of a Massachusetts business trust
may, under certain circumstances, be held personally liable as partners for its
obligations and liabilities. However, the Declaration of Trust contains an
express disclaimer of shareholder liability for acts or obligations of each Fund
and provides for indemnification and reimbursement of expenses out of Fund
property for any shareholder held personally liable for the obligations of a
particular Fund. The Declaration of Trust also provides for the maintenance, by
or on behalf of the Trust and the Funds, of appropriate insurance (for example,
fidelity bonding and errors and omissions insurance) for the protection of the
Funds, their shareholders, Trustees, officers, employees and agents covering
possible tort and other liabilities. Thus, the risk of a shareholder incurring
financial loss on account of shareholder liability is limited to circumstances
in which both inadequate insurance existed and a Fund itself was unable to meet
its obligations.

                                   APPENDIX A
 
                        DESCRIPTION OF SECURITY RATINGS
 
STANDARD & POOR'S
 
  Corporate and Municipal Bonds
 
     AAA -- Debt rated AAA have the highest rating assigned by Standard & Poor's
to a debt obligation. Capacity to pay interest and repay principal is extremely
strong.
 
     AA -- Debt rated AA have a very strong capacity to pay interest and repay
principal and differ from the highest rated issues only in a small degree.
 
     A -- Debt rated A have a strong capacity to pay interest and repay
principal although they are somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions than debts in higher rated
categories.
 
     BBB -- Debt rated BBB are regarded as having an adequate capacity to pay
interest and repay principal. Whereas they normally exhibit adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debts in this category than for debts in higher rated categories.
 
     BB -- Debt rated BB is regarded as having less near-term vulnerability to
default than other speculative issues. However, it faces major ongoing
uncertainties or exposure to adverse business, financial or economic conditions
which could lead to inadequate capacity to meet timely interest and principal
payments.
 
  Commercial Paper, including Tax Exempt
 
     A -- Issues assigned this highest rating are regarded as having the
greatest capacity for timely payment. Issues in this category are further
refined with the designations 1, 2, and 3 to indicate the relative degree of
safety.
 
     A-1 -- This designation indicates that the degree of safety regarding
timely payment is very strong.
 
MOODY'S
 
  Corporate and Municipal Bonds
 
     AAA -- Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edge". Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.
 
     AA -- Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long term risks appear somewhat larger than in Aaa securities.
 
     A -- Bonds which are rated A possess many favorable investment attributes
and are to be considered as upper medium grade obligations. Factors giving
security to principal and interest are considered adequate but elements may be
present which suggest a susceptibility to impairment sometime in the future.
 
     BAA -- Bonds which are rated Baa are considered as medium grade
obligations, i.e., they are neither highly protected nor poorly secured.
Interest payments and principal security appear adequate for the present but
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.
 
                                       37
<PAGE>   79
 
     BA -- Bonds which are rated Ba are judged to have speculative elements;
their future cannot be considered as well-assured. Often the protection of
interest and principal payments may be very moderate, and thereby not well
safeguarded during both good and bad times over the future. Uncertainty of
position characterizes bonds in this class.
 
  Commercial Paper
 
     PRIME-1 -- Issuers rated P-1 (or related supporting institutions) have a
superior capacity for repayment of short-term promissory obligations. Prime-1
repayment capacity will normally be evidenced by the following characteristics:
 
          -- Leading market positions in well established industries.
          -- High rates of return on funds employed.
          -- Conservative capitalization structures with moderate reliance on
     debt and ample asset protection.
          -- Broad margins in earnings coverage of fixed financial charges and
     high internal cash generation.
          -- Well established access to a range of financial markets and assured
     sources of alternate liquidity.

ITEM 27.  INDEMNIFICATION.
 
     Reference is made to Article V of the Registrant's Declaration of Trust,
filed as Exhibit 1 to Pre-Effective Amendment No. 1 dated April 29, 1993 to
Registration Statement -- Registration No. 33-61810 under the Securities Act of

     Insofar as indemnification for liability arising under the Securities Act
of 1933, as amended (the "1933 Act"), may be permitted to Trustees, officers and
controlling persons of the Trust pursuant to the Trust's Declaration of Trust,
or otherwise, the Trust has been advised that in the opinion of the SEC such
indemnification is against public policy as expressed in the 1933 Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Trust of expenses incurred or
paid by a Trustee, officer or controlling person of the Trust in the successful
defense of any action, suit or proceeding) is asserted by such Trustee, officer
or controlling person in connection with the securities being registered, the
Trust will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the 1933 Act and will be governed by the final adjudication of such
issue.

     Not applicable.

     (c) Insofar as indemnification for liability arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
