INVESTMENT OBJECTIVE
AND POLICIES
         _______________________________________________________________________
 
GOVERNMENT PORTFOLIO
                     The Government Portfolio seeks to preserve principal value
                     and maintain a high degree of liquidity while providing
                     current income. Under normal market conditions, the
                     Portfolio invests exclusively in (i) U.S. Treasury
                     obligations; (ii) obligations issued or guaranteed as to
                     principal and interest by the agencies or instrumentalities
                     of the U.S. Government; and (iii) repurchase agreements
                     involving such obligations.
 
                           There can be no assurance that the Portfolio will
                     achieve its investment objective.
 
GENERAL INVESTMENT
POLICIES
     ___________________________________________________________________________
 
                     In purchasing obligations, the Portfolio complies with the
                     requirements of Rule 2a-7 under the Investment Company Act
                     of 1940 (the "1940 Act"), as that Rule may be amended from
                     time to time. These requirements currently provide that the
                     Portfolio must limit its investments to securities with
                     remaining maturities of 397 days or less, and must maintain
                     a dollar-weighted average maturity of 90 days or less. In
                     addition, under Rule 2a-7, the Portfolio may only invest in
                     securities (other than U.S. Government Securities) rated in
                     one of the two highest categories for short-term securities
                     by at least two nationally recognized statistical rating
                     organizations ("NRSROs") (or by one NRSRO if only one NRSRO
                     has rated the security), or, if unrated, determined by the
                     Adviser (in accordance with procedures adopted by the
                     Trust's Board of Trustees) to be of equivalent quality to
                     rated securities in which the Portfolio may invest.
                     Purchases by the Portfolio of unrated securities and
                     securities rated by only one NRSRO must be ratified by the
                     Trust's Board of Trustees.
 
                           Securities rated in the highest rating category by at
                     least two NRSROs (or, if unrated, determined by the Adviser
                     to be of comparable quality) are "first tier" securities.
                     Non-first tier securities rated in the second highest
                     rating category by at least one NRSRO (or, if unrated,
                     determined by the Adviser to be of comparable quality) are
                     considered to be "second tier" securities. The Portfolio
                     may invest, in the aggregate, no more than 5% of its assets
                     in second tier securities, and an investment in any one
                     second tier security is limited to the greater of 1% of the
                     Portfolio's total assets or $1 million. A taxable money
 
                                                                               4
<PAGE>
                     market fund may also hold more than 5% of its total assets
                     in the first tier securities of a single issuer for three
                     business days.
 
                           Although the Portfolio is governed by Rule 2a-7, its
                     investment policies are, in certain respects, more
                     restrictive than those imposed by that Rule.
 
                           The Portfolio may invest up to 10% of its net assets
                     in illiquid securities. However, restricted securities,
                     including Rule 144A securities and Section 4(2) commercial
                     paper, that meet the criteria established by the Board of
                     Trustees of the Trust will be considered liquid. In
                     addition, the Portfolio may invest in U.S. Treasury STRIPS
                     (as defined in the "Description of Permitted Investments
                     and Risk Factors").
 
                           The Portfolio may purchase securities on a
                     when-issued basis.
 
                           For a description of the permitted investments and
                     the above ratings see "Description of Permitted Investments
                     and Risk Factors" and the Statement of Additional
                     Information.
 
INVESTMENT LIMITATIONS
        ________________________________________________________________________
 
                     The investment objectives and certain of the investment
                     limitations are fundamental policies of the Portfolio. It
                     is a fundamental policy of the Portfolio to use its best
                     efforts to maintain a constant net asset value of $1.00 per
                     share. There can be no assurance that the Portfolio will
                     achieve its investment objective, or that the Portfolio
                     will be able to maintain a net asset value of $1.00 per
                     share on a continuing basis.
 
                           Fundamental policies cannot be changed with respect
                     to the Trust or the Portfolio without the consent of the
                     holders of a majority of the Trust or the Portfolio's
                     outstanding shares.
 
                     THE PORTFOLIO MAY NOT:
 
                     1. Purchase securities of any issuer (except securities
                       issued or guaranteed by the U.S. Government, its agencies
                       or instrumentalities), if as a result, more than 5% of
                       the total assets of the Portfolio would be invested in
                       the securities of such issuer; provided, however, that
                       the Portfolio may invest up to 25% of its total assets
                       without regard to this restriction as permitted by Rule
                       2a-7 under the 1940 Act.
 
                     2. Purchase any securities which would cause more than 25%
                       of the total assets of the Portfolio to be invested in
                       the securities of one or more issuers conducting their
                       principal business activities in the same industry,
                       provided that this limitation does not apply to
                       investments in (a) domestic banks and (b) obligations
                       issued or guaranteed by the U.S. Government or its
                       agencies and instrumentalities.
 
                     3. Borrow money except for temporary or emergency purposes
                       and then only in an amount not exceeding 10% of the value
                       of the total assets of the Portfolio. This borrowing
                       provision is included solely to facilitate the orderly
                       sale of portfolio securities to accommodate substantial
                       redemption requests if they should occur and is not for
                       investment purposes. All borrowings will be repaid before
                       making additional investments
 
                                                                               5
<PAGE>
                       for the Portfolio and any interest paid on such
                       borrowings will reduce the income of the Portfolio.
 
                     The foregoing percentage limitations (except the limitation
                     on borrowing) will apply at the time of the purchase of a
                     security. Additional fundamental and non-fundamental
                     investment limitations are set forth in the Statement of
                     Additional Information.
THE MANAGER
          ______________________________________________________________________
 
                     SEI Fund Management (the "Manager" or the "Transfer
                     Agent"), a wholly-owned subsidiary of SEI Investments
                     Company ("SEI"), and the Trust are parties to a management
                     agreement (the "Management Agreement"). Under the terms of
                     the Management Agreement, the Manager is responsible for
                     (i) providing the Trust with overall management services,
                     regulatory reporting, all necessary office space,
                     equipment, personnel and facilities and (ii) acting as
                     transfer agent, dividend disbursing agent, and shareholder
                     servicing agent.
 
                           For these services, the Manager is entitled to a fee,
                     which is calculated daily and paid monthly, at an annual
                     rate of the Portfolio's average daily net assets as
                     follows: Government Portfolio--.24%. The Manager has
                     contractually agreed to waive up to all of its fee and, if
                     necessary, pay other operating expenses in order to limit
                     the total operating expenses to not more than .75% of the
                     Class C shares of the Government Portfolio on an annualized
                     basis. The Manager has voluntarily agreed to waive up to
                     all of its fee in order to limit total operating expenses
                     to not more than .70% of the daily net assets of Class C
                     shares of the Government Portfolio on an annualized basis.
                     The Manager reserves the right, in its sole discretion, to
                     terminate these voluntary waivers at any time. For the
                     fiscal year ended January 31, 1996, Government Portfolio
                     paid management fees, after waivers, of .12% of its average
                     daily net assets.
THE ADVISER
         _______________________________________________________________________
 
                     Wellington Management Company, LLP (the "Adviser" or "WMC")
                     serves as the investment adviser for the Portfolio under an
                     advisory agreement with the Trust. The Adviser is a
                     professional investment counseling firm which provides
                     investment services to investment companies, employee
                     benefit plans, endowments, foundations, and other
                     institutions and individuals. Under the advisory agreement,
                     the Adviser invests the assets of the Portfolio and
                     continuously reviews, supervises and administers the
                     Portfolio's investment program. The Adviser is independent
                     of the Manager and SEI and discharges its responsibilities
                     subject to the supervision of, and policies set by, the
                     Trustees of the Trust.
 
                           The Adviser's predecessor organizations have provided
                     investment advisory services to investment companies since
                     1933 and to investment counseling clients since 1960. As of
                     March 31, 1996, the Adviser had discretionary management
                     authority with respect to approximately $114.1 billion of
                     assets, including the assets of the Trust and SEI Liquid
 
                                                                               6

                           The Adviser is entitled to a fee, which is calculated
                     daily and paid monthly, at an annual rate of .075% of the
                     combined average daily net assets of the Portfolios of the
                     Trust up to $500 million and .02% of such combined average
                     daily net assets in excess of $500 million. Such fees are
                     allocated daily among the Portfolios on the basis of their
                     relative net assets. For the fiscal year ended January 31,
                     1996, the Government Portfolio paid the Adviser advisory
                     fees, after fee waivers, of .01% of its relative net
                     assets.
 
DISTRIBUTION AND
SHAREHOLDER
SERVICING
      __________________________________________________________________________
 
                     SEI Financial Services Company (the "Distributor"), a
                     wholly-owned subsidiary of SEI, serves as each Portfolio's
                     distributor pursuant to a distribution agreement (the
                     "Distribution Agreement") with the Trust.
 
                           The Portfolio has adopted plans under which firms,
                     including the Distributor, that provide shareholder and
                     administrative services may receive compensation therefor.
                     The Class A, B and C plans differ in a number of ways,
                     including the amounts that may be paid. Under each plan,
                     the Distributor may provide those services itself or may
                     enter into arrangements under which third parties provide
                     such services and are compensated by the Distributor. Under
                     such arrangements the Distributor may retain as a profit
                     any difference between the fee it receives and the amount
                     it pays such third party. In addition, the Portfolios may
                     enter into such arrangements directly.
 
                           Under the Class C shareholder service plan, the
                     Portfolio will pay shareholder service fees at an annual
                     rate of up to .25% of its average daily net assets in
                     return for the Distributor's (or its agent's) efforts in
                     maintaining client accounts; arranging for bank wires;
                     responding to client inquiries concerning services provided
                     or investments; and assisting clients in changing dividend
                     options, account designations and addresses. In addition,
                     the Class C shares may pay administrative services fees at
                     specified percentages of the average daily net assets of
                     the shares of the Class (up to .25%). Administrative
                     services include providing sub-accounting; providing
                     information on share positions to clients; forwarding
                     shareholder communications to clients; processing purchase,
                     exchange and redemption orders; and processing dividend
                     payments.
 
                           It is possible that an institution may offer
                     different classes of shares to its customers and thus
                     receive compensation with respect to different classes.
                     These financial institutions may also charge separate fees
                     to their customers. Certain financial institutions
 
                                                                               7

                     offering shares to their customers may be required to
                     register as dealers pursuant to state laws.
 
                           The Distributor may, from time to time in its sole
                     discretion, institute one or more promotional incentive
                     programs, which will be paid by the Distributor from its
                     own resources. Under any such program, the Distributor will
                     provide promotional incentives, in the form of cash or
                     other compensation, including merchandise, airline
                     vouchers, trips and vacation packages, to all dealers
                     selling shares of the Portfolio. Such promotional
                     incentives will be offered uniformly to all dealers and
                     predicated upon the amount of shares of the Portfolios sold
                     by the dealer.
 
PURCHASE AND
REDEMPTION OF SHARES
    ____________________________________________________________________________
 
                     Financial institutions may acquire shares of the Portfolio
                     for their own accounts, or as a record owner on behalf of
                     fiduciary, agency or custody accounts, by placing orders
                     with the Transfer Agent. Institutions that use certain SEI
                     proprietary systems may place orders electronically through
                     those systems. Financial institutions may impose an earlier
                     cut-off time for receipt of purchase orders directed
                     through them to allow for processing and transmittal of
                     these orders to the Transfer Agent for effectiveness on the
                     same day. Financial institutions that purchase shares for
                     the accounts of their customers may impose separate charges
                     on these customers for account services.
 
                           Shares of the Portfolio may be purchased or redeemed
                     on days on which the New York Stock Exchange is open for
                     business ("Business Days"). However, money market fund
                     shares cannot be purchased by Federal Reserve wire on
                     Federal holidays restricting wire transfers.
 
                           Shareholders who desire to purchase shares with cash
                     must place their orders with the Transfer Agent (or its
                     authorized agent) prior to the determination of net asset
                     value for the order to be accepted on that Business Day.
                     Cash investments must be transmitted or delivered in
                     federal funds to the wire agent by the close of business on
                     the same day the order is placed. The Trust reserves the
                     right to reject a purchase order when the Distributor
                     determines that it is not in the best interest of the Trust
                     or shareholders to accept such purchase order.
 
                           The Trust will send shareholders a statement of
                     shares owned after each transaction. The purchase price of
                     shares is the net asset value next determined after a
                     purchase order is received and accepted by the Trust, which
                     is expected to remain constant at $1.00. The net asset
                     value per share of the Portfolio is determined by dividing
                     the total value of its investments and other assets, less
                     any liabilities, by the total number of outstanding shares
                     of the Portfolio. The Portfolio's investments will be
                     valued by the amortized cost method described in the
                     Statement of Additional Information. Net asset value per
                     share is determined daily as of 4:30 p.m. Eastern time on
                     each Business Day.
 
                                                                               8
<PAGE>
                     Financial institutions which purchase and redeem shares for
                     the accounts of their customers may impose their own
                     cut-off times for receipt of purchase and redemption
                     requests directed through them.
 
                           Shareholders who desire to redeem shares of a
                     Portfolio must place their redemption orders with the
                     Transfer Agent (or its authorized agent) prior to the
                     determination of net asset value on any Business Day. The
                     redemption price is the net asset value per share of the
                     Portfolio next determined after receipt by the Transfer
                     Agent of the redemption order. Payment on redemptions will
                     be made as promptly as possible and, in any event, within
                     seven days after the redemption order is received.
 
                           Shareholders who desire to purchase or redeem shares
                     of the Portfolio after 2:00 p.m. Eastern time must contact
                     the Transfer Agent one week in advance to establish the
                     requisite operational requirements for late day trading.
                     Even after these procedures are in place, investors are
                     encouraged to execute as many trades as possible prior to
                     2:00 p.m. Eastern time.
 
                           Shareholders who wish to receive same-day acceptance
                     of investment in the Portfolio after 2:00 p.m. Eastern time
                     must contact the Transfer Agent before 4:30 p.m. Eastern
                     time to place the trade and must obtain a security code
                     number for each trade. It is necessary to obtain a new
                     security code number for each purchase placed in the
                     Portfolio after 2:00 p.m. Eastern time. Security code
                     numbers are assigned exclusively by means of telephone
                     communications and are effective for one transaction only
                     and may not be used more than once.
 
                           Purchase and redemption orders may be placed by
                     telephone. Neither the Trust nor the Trust's Transfer Agent
                     will be responsible for any loss, liability, cost or
                     expense for acting upon wire instructions or upon telephone
                     instructions that it reasonably believes to be genuine. The
                     Trust and the Trust's Transfer Agent will each employ
                     reasonable procedures to confirm that instructions
                     communicated by telephone are genuine, including requiring
                     a form of personal identification prior to acting upon
                     instructions received by telephone and recording telephone
                     instructions.
 
                           If market conditions are extraordinarily active, or
                     other extraordinary circumstances exist, shareholders may
                     experience difficulties placing redemption orders by
                     telephone, and may wish to consider placing orders by other
                     means.
PERFORMANCE
          ______________________________________________________________________
 
                     For the Portfolio, the performance of Class A shares will
                     normally be higher than that of Class B shares because of
                     the additional shareholder servicing expenses charged Class
                     B shares. Likewise, the performance on Class B shares will
                     normally be higher than that of Class C or Class G shares
                     because of the additional administrative services expenses
                     charged to Class C shares and the additional distribution
                     and shareholder servicing expenses charged to Class G
                     shares.
 
                                                                               9
<PAGE>
                           From time to time, the Portfolio may advertise the
                     "current yield" and "effective yield" (also called
                     "effective compound yield"). These figures are based on
                     historical earnings and are not intended to indicate future
                     performance. No representation can be made concerning
                     actual future yields or returns. The "current yield" of the
                     Portfolio refers to the income generated by a hypothetical
                     investment in the Portfolio over a seven-day period (which
                     period will be stated in the advertisement). This income is
                     then "annualized," i.e., the income generated during that
                     week is assumed to be generated each week over a 52-week
                     period and is shown as a percentage of the investment. The
                     "effective yield" (also called "effective compound yield")
                     is calculated similarly but, when annualized, the income
                     earned by an investment in the Portfolio is assumed to be
                     reinvested. The "effective yield" will be slightly higher
                     than the "current yield" because of the compounding effect
                     of this assumed reinvestment.
 
                           The Portfolio may periodically compare its
                     performance to that of: (i) other mutual funds tracked by
                     mutual fund rating services (such as Lipper Analytical) or
                     financial and business publications and periodicals; (ii)
                     broad groups of comparable mutual funds; (iii) unmanaged
                     indices which may assume investment of dividends but
                     generally do not reflect deductions for administrative and
                     management costs; or (iv) to other investment alternatives.
                     The Portfolio may also quote financial and business
                     publications and periodicals as they relate to fund

TAXES
  ______________________________________________________________________________
 
                     The following summary of federal income tax consequences is
                     based on current tax laws and regulations, which may be
                     changed by legislative, judicial or administrative action.
                     No attempt has been made to present a detailed explanation
                     of the federal, state or local income tax treatment of the
                     Portfolio or its shareholders. Accordingly, shareholders
                     are urged to consult their tax advisers regarding specific
                     questions as to federal, state and local income taxes.
                     State and local tax consequences of an investment in the
                     Portfolio may differ from the federal income tax
                     consequences described below. Additional information
                     concerning taxes is set forth in the Statement of
                     Additional Information.
TAX STATUS
OF THE PORTFOLIO
                     The Portfolio is treated as a separate entity for federal
                     income tax purposes and is not combined with the Trust's
                     other portfolios. The Portfolio intends to qualify or to
                     continue to qualify for the special tax treatment afforded
                     regulated investment companies ("RICs") under Subchapter M
                     of the Internal Revenue Code of 1986, as amended (the
                     "Code"), so as to be relieved of federal income tax on net
                     investment company taxable income and net capital gains
                     (the excess of net long-term capital gains over net
                     short-term capital losses) distributed to shareholders.
TAX STATUS
OF DISTRIBUTIONS
                     The Portfolio distributes substantially all of its net
                     investment income (including net short-term capital gains)
                     to shareholders. Dividends from net investment company
                     taxable income are taxable to its shareholders as ordinary
                     income (whether received in cash or in
 
                                                                              10
<PAGE>
                     additional shares) and will not qualify for the corporate
                     dividends received deduction. Distributions of net capital
                     gains are taxable to shareholders as long-term capital
                     gains. The Portfolio provides annual reports to
                     shareholders of the federal income tax status of all
                     distributions.
 
                           Dividends declared by the Portfolio in October,
                     November or December of any year and payable to
                     shareholders of record on a date in such a month, will be
                     deemed to have been paid by the Portfolio and received by
                     the shareholders on December 31 of the year declared if
                     paid by the Portfolio at any time during the following
                     January.
 
                           Income received on direct U.S. Government obligations
                     is exempt from tax at the state level when received
                     directly and may be exempt, depending on the state, when
                     received by a shareholder from the Portfolio provided
                     certain conditions are satisfied. Interest received on
                     repurchase agreements collateralized by U.S. Government
                     obligations normally is not exempt from state taxation. The
                     Portfolio will inform shareholders annually of the
                     percentage of income and distributions derived from direct
                     U.S. Government obligations. Shareholders should consult
                     their tax advisers to determine whether any portion of the
                     income dividends received from the Portfolio is considered
                     tax exempt in their particular states.
 
                           With respect to investments in U.S. Treasury STRIPS,
                     which are sold at original issue discount and thus do not
                     make periodic cash interest payments, the Portfolio will be
                     required to include as part of its current income the
                     accreted interest on any such obligations even though the
                     Portfolio has not received any interest payments on such
                     obligations during that period. Because the Portfolio
                     distributes all of its net investment income to its
                     shareholders, the Portfolio may have to sell portfolio
                     securities to distribute such imputed income, which may
                     occur at a time when the Adviser would not have chosen to
                     sell such securities, and which may result in a taxable
                     gain or loss.
 
                           The Portfolio intends to make sufficient
                     distributions to avoid liability for the federal excise tax
                     applicable to RICs.
 
                           Each sale, exchange, or redemption of Portfolio
                     shares is a taxable transaction to the shareholder.
GENERAL INFORMATION
                  ______________________________________________________________
THE TRUST
                     The Trust was organized as a Massachusetts business trust
                     under a Declaration of Trust dated March 15, 1982. The
                     Declaration of Trust permits the Trust to offer separate
                     portfolios of shares and different classes of each
                     portfolio. In addition to the Portfolio, the Trust consists
                     of the following portfolios: Short-Duration Government
                     Portfolio (formerly, Short-Term Government Portfolio),
                     Intermediate-Duration Government Portfolio (formerly,
                     Intermediate-Term Government Portfolio), GNMA Portfolio,
                     Short-Duration Mortgage Portfolio (formerly, Short-Term
                     Mortgage Portfolio), Corporate Daily Income Portfolio,
                     Government Securities Daily Income Portfolio, Federal
                     Securities Portfolio, Money Market Portfolio, Prime
                     Obligation Portfolio, Government II Portfolio, Treasury
                     Portfolio and
 
                                                                              11
<PAGE>
                     Treasury II Portfolio. All consideration received by the
                     Trust for shares of any portfolio and all assets of such
                     portfolio belong to that portfolio and would be subject to
                     liabilities related thereto.
 
                           The Trust pays its expenses, including fees of its
                     service providers, audit and legal expenses, expenses of
                     preparing prospectuses, proxy solicitation materials and
                     reports to shareholders, costs of custodial services and
                     registering the shares under state and federal securities
                     laws, pricing, insurance expenses, litigation and other
                     extraordinary expenses, brokerage costs, interest charges,
                     taxes and organization expenses.
TRUSTEES OF THE TRUST
                     The management and affairs of the Trust are supervised by
                     the Trustees under the laws of The Commonwealth of
                     Massachusetts. The Trustees have approved contracts under
                     which, as described above, certain companies provide
                     essential management services to the Trust.
VOTING RIGHTS
                     Each share held entitles the shareholder of record to one
                     vote. The shareholders of each portfolio or class will vote
                     separately on matters relating solely to that Portfolio or
                     class. As a Massachusetts business trust, the Trust is not
                     required to hold annual meetings of shareholders, but
                     approval will be sought for certain changes in the
                     operation of the Trust and for the election of Trustees
                     under certain circumstances. In addition, a Trustee may be
                     removed by the remaining Trustees or by shareholders at a
                     special meeting called upon written request of shareholders
                     owning at least 10% of the outstanding shares of the Trust.
                     In the event that such a meeting is requested, the Trust
                     will provide appropriate assistance and information to the
                     shareholders requesting the meeting.
REPORTING
                     The Trust issues an unaudited report semi-annually and
                     audited financial statements annually. The Trust furnishes
                     proxy statements and other reports to shareholders of
                     record.
SHAREHOLDER INQUIRIES
                     Shareholder inquiries should be directed to the Manager,
                     SEI Fund Management, Oaks, Pennsylvania 19456.
DIVIDENDS
                     Substantially all of the net investment income (exclusive
                     of capital gains) of the Portfolio is distributed in the
                     form of monthly dividends. The dividends are determined and
                     declared as a dividend for shareholders of record on the
                     close of business on that day. Dividends are paid by the
                     Portfolio in federal funds or in additional shares at the
                     discretion of the shareholder on the first Business Day of
                     each month. The dividends on Class A shares are normally
                     higher than those on Class B shares of the Portfolio
                     because of the additional shareholder servicing expenses
                     charged to Class B shares. Likewise, the dividends on Class
                     B shares are normally higher than those on Class C or Class
                     G shares of the Portfolio because of the additional
                     administrative services expenses charged to Class C shares
                     and the additional distribution and shareholder servicing
                     expenses charged to Class G shares.

DESCRIPTION OF
PERMITTED INVESTMENTS
AND RISK FACTORS
    ____________________________________________________________________________
 
                     The following is a description of certain of the permitted
                     investment practices for the Portfolio and the associated
                     risk factors:
DEMAND INSTRUMENTS
                     Certain instruments may entail a demand feature which
                     permits the holder to demand payment of the principal
                     amount of the instrument. Demand instruments may include
                     variable rate master demand notes.
ILLIQUID SECURITIES
                     Illiquid securities are securities which cannot be disposed
                     of within seven business days at approximately the price at
                     which they are being carried on the Portfolio's books.
                     Illiquid securities include demand instruments with a
                     demand notice periods exceeding seven days, securities for
                     which there is no active secondary market, and repurchase
                     agreements with maturities or durations of more than seven
                     days in length.
REPURCHASE AGREEMENTS
                     Repurchase agreements are agreements by which the Portfolio
                     obtains a security and simultaneously commits to return the
                     security to the seller at an agreed upon price on an agreed
                     upon date. The Portfolio will have actual or constructive
                     possession of the security as collateral for the repurchase
                     agreement. The Portfolio bears a risk of loss in the event
                     the other party defaults on its obligations and the
                     Portfolio is delayed or prevented from exercising its right
                     to dispose of the collateral or if the Portfolio realizes a
                     loss on the sale of the collateral. The Portfolio will
                     enter into repurchase agreements only with financial
                     institutions deemed to present minimal risk of bankruptcy
                     during the term of the agreement based on established
                     guidelines. Repurchase agreements are considered loans
                     under the 1940 Act.
U.S. GOVERNMENT AGENCY SECURITIES
                     Obligations issued or guaranteed by agencies of the U.S.
                     Government, including, among others, the Federal Farm
                     Credit Bank, the Federal Housing Administration and the
                     Small Business Administration, and obligations issued or
                     guaranteed by instrumentalities of the U.S. Government,
                     including, among others, the Federal Home Loan Mortgage
                     Corporation, the Federal Land Banks and the U.S. Postal
                     Service. Some of these securities are supported by the full
                     faith and credit of the U.S. Treasury (e.g., Government
                     National Mortgage Association securities), others are
                     supported by the right of the issuer to borrow from the
                     Treasury (e.g., Federal Farm Credit Bank securities), while
                     still others are supported only
 
                                                                              13
<PAGE>
                     by the credit of the instrumentality (e.g., Fannie Mae
                     securities). Guarantees of principal by agencies or
                     instrumentalities of the U.S. Government may be a guarantee
                     of payment at the maturity of the obligation so that in the
                     event of a default prior to maturity there might not be a
                     market and thus no means of realizing on the obligation
                     prior to maturity. Guarantees as to the timely payment of
                     principal and interest do not extend to the value or yield
                     of these securities nor to the value of the Portfolio's
                     shares.
U.S. TREASURY OBLIGATIONS
                     U.S. Treasury obligations consist of bills, notes and bonds
                     issued by the U.S. Treasury, as well as separately traded
                     interest and principal component parts of such obligations
                     known as Separately Traded Registered Interest and
                     Principal Securities ("STRIPS") that are transferable
                     through the federal book-entry system.
U.S. TREASURY STRIPS
                     STRIPS are sold as zero coupon securities which means that
                     they are sold at a substantial discount and redeemed at
                     face value at their maturity date without interim cash
                     payments of interest or principal. This discount is
                     accreted over the life of the security, and such accretion
                     will constitute the income earned on the security for both
                     accounting and tax purposes. Because of these features,
                     such securities may be subject to greater interest rate
                     volatility than interest-paying investments. See also
                     "Taxes."
VARIABLE AND FLOATING RATE INSTRUMENTS
                     Certain obligations may carry variable or floating rates of
                     interest, and may involve a conditional or unconditional
                     demand feature. Such instruments bear interest at rates
                     which are not fixed, but which vary with changes in
                     specified market rates or indices. The interest rates on
                     these securities may be reset daily, weekly, quarterly or
                     some other reset period, and may have a floor or ceiling on
                     interest rate changes. There is a risk that the current
                     interest rate on such obligations may not accurately
                     reflect existing market interest rates. A demand instrument
                     with a demand notice exceeding seven days may be considered
                     illiquid if there is no secondary market for such security.
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES
                     When-issued or delayed delivery transactions involve the
                     purchase of an instrument with payment and delivery taking
                     place in the future. Delivery of and payment for these
                     securities may occur a month or more after the date of the
                     purchase commitment. The Portfolio will maintain with the
                     Custodian a separate account with liquid, high grade debt
                     securities or cash in an amount at least equal to these
                     commitments. The interest rate realized on these securities
                     is fixed as of the purchase date, and no interest accrues
                     to the Portfolio before settlement. These securities are
                     subject to market fluctuation due to changes in market
                     interest rates, and it is possible that the market value at
                     the time of settlement could be higher or lower than the
                     purchase price if the general level of interest rates has
                     changed. Although the Portfolio generally purchases
                     securities on a when-issued or forward commitment basis
                     with the intention of actually acquiring securities, the
                     Portfolio may dispose of a when-issued security or forward
                     commitment prior to settlement if the Adviser deems it
                     appropriate to do so.
