OBLIGATIONS OF OR OTHERWISE SUPPORTED BY THE U.S. GOVERNMENT, ANY CREDIT UNION
OR BY THE NATIONAL CREDIT UNION SHARE INSURANCE FUND, THE NATIONAL CREDIT UNION
ADMINISTRATION OR ANY OTHER GOVERNMENT AGENCY.  AN INVESTMENT IN THE PORTFOLIOS
INVOLVES RISK INCLUDING POSSIBLE LOSS OF PRINCIPAL.

                                  INTRODUCTION
    
Each Portfolio is a separate, diversified portfolio of Trust for Credit Unions
(the "Fund"), an open-end, management investment company. 

The Portfolios are designed for state and federally chartered credit unions and
credit union service organizations which seek higher current yields than a
three-year Treasury note from a "high quality" mortgage-related securities
portfolio that will terminate within a prescribed period.  "High quality"
securities are rated, at the time of purchase, in one of the two highest rating
categories by a nationally recognized statistical rating organization ("NRSRO")
and also include securities issued or guaranteed by the U.S. Government, its
agencies, instrumentalities or sponsored enterprises.  Investment in the
Portfolio relieves investors from the administrative and accounting burdens
involved in direct investments, and also provides related benefits as described
below.      

High Current Income.  Each Portfolio seeks to achieve a high level of current
- --------------------                                                         
income.  In considering whether a Portfolio has achieved this objective, the
investment adviser will compare such Portfolio's yield to that of a three-year
Treasury note maturing on or about February 15, 1997 and May 15, 1997, for the
Target Maturity Portfolio (Feb 97) and Target Maturity Portfolio (May 97).
Unlike U.S. Treasury notes, it is expected that most investments made by a
Portfolio will not be backed by the full faith and credit of the U.S.
Government, and many investments will not be insured or guaranteed by any
government agency.

By selecting a term of three years, each Portfolio hopes to take advantage of a
portion of the yield curve that the investment adviser believes to be relatively
undervalued.  In the investment adviser's view, this section of the curve has
historically offered a very attractive risk/return profile.

Preservation of Capital.  Each Portfolio will seek to attain its objective to
- ------------------------                                                     
return $10 per unit by (1) preserving capital through active portfolio
management, including the purchase and sale of securities to change the
Portfolio's option-adjusted duration (see "Description of Investments -- Other
Portfolio Management Policies" in the Prospectus) and (2) reducing, over time,
the price sensitivity of a Portfolio to changes in interest rates in light of
expected cash flows and mortgage prepayments under different interest rate
scenarios.  Duration, which is a measure of the price sensitivity of a
Portfolio, including expected cash flows and mortgage prepayments under a wide
range of interest rate scenarios, is reviewed and recalculated daily.  In
connection with each Portfolio's goal to preserve capital, the investment
adviser will seek to limit a Portfolio's price volatility to that of a three-
year Treasury note maturing on or

                                      B-3
<PAGE>
 
    
about February 15, 1997 and May 15, 1997, respectively.  However, there is no
assurance that the investment adviser's strategies will be successful.  Each
Portfolio's net asset value per unit will fluctuate more than that of a money
market fund. There can be no assurance that Goldman, Sachs & Co.'s estimation of
a Portfolio's duration will be accurate or that the duration of a Portfolio will
always remain within the maximum target duration described above.      

Liquidity.  Because a Portfolio's units may be redeemed, subject to the
- ----------                                                             
redemption fee for early withdrawal, upon request of its unitholder on any
Business Day, a Portfolio offers greater liquidity than many competing
investments such as certificates of deposit and direct investments in certain
mortgage-related securities.
    
Experienced Professional Management.  Successfully creating and managing a
- ------------------------------------                                      
diversified portfolio of mortgage-related securities requires professionals with
extensive experience.  Members of Goldman, Sachs & Co.'s highly skilled
portfolio management team bring together many years of experience in the
analysis, valuation and trading of U.S. fixed income securities.  At November
30, 1996, they were responsible for approximately $23.8 billion in fixed income
assets including approximately $6.9 billion in mortgage-related securities. 
     

A Sophisticated Investment Process.  The Portfolios' investment process starts
- -----------------------------------                                           
with a review of trends for the overall economy as well as for different sectors
of the U.S. mortgage market.   Goldman, Sachs & Co.'s portfolio managers then
analyze yield spreads, implied volatility and the shape of the yield curve.

In planning each Portfolio's strategies, the managers are able to draw upon
certain fundamental analysis and proprietary technical models of Goldman, Sachs
& Co.  Among the quantitative techniques used in the Portfolio's investment
process are:

 .    option-adjusted analytics to make initial strategic asset allocations
     within the mortgage markets and to reevaluate investments as market
     conditions change; and

 .    analytics to estimate mortgage prepayments and cash flows under different
     interest rate scenarios and to maintain an optimal portfolio structure.

The Portfolio managers may use these and other trading and hedging techniques in
response to market and interest rate conditions.  In particular, these and other
evaluative tools help the portfolio managers select securities with investment
characteristics they believe are desirable.

                                      B-4

Convenience of a Fund Structure.  The Portfolios eliminate many of the
- --------------------------------                                      
complications that direct ownership of mortgage securities entail.  For example,
most mortgage-related securities generate monthly payments of both principal and
interest, just as the underlying mortgages do.  To conserve their principal,
investors must make a special effort to segregate and reinvest the principal
portion of each payment on their own.  Each Portfolio relieves investors of this
chore by automatically reinvesting all principal payments within a Portfolio and
distributing only current income each month.

Laddered Maturities Program.  The Fund designed the program specifically for
- ---------------------------                                                
credit unions with the help of a team of CFO's from leading credit unions.  The
Portfolios that comprise the program may assist investors that wish to "ladder"
a portfolio (that is, construct a portfolio of securities with progressive
maturity dates) or match or hedge liabilities.  A laddering strategy can be a
simple, convenient and effective method of establishing a disciplined, long-term
approach to investing.  Specifically, a laddering strategy involves structuring
a portfolio so that a designated amount of money is invested continuously for a
fixed period on an ongoing basis.  Laddering a portion of an investment
portfolio can result in more stable investment income, maturities timed to
coincide with cash flows, and maintenance of a conservative, interest rate
neutral approach to investing.  Credit unions have typically used Treasury
securities, agency securities or certificates of deposit as core investments in
a laddering strategy.  Unlike Treasury notes, investments in units of a
portfolio are not backed by the full faith and credit of the U.S. Government nor
issued or guaranteed by any government agency.  Unlike certificates of deposit,
portfolio units do not provide a fixed yield for a stated period of time, and
return of principal is not assured.

Maturity Portfolio (May 97).  After the initial term for a Portfolio, the
Advisory Agreement will continue from year to year thereafter with respect to a
Portfolio provided such continuance is specifically approved at least annually
(a) by the vote of a majority of the outstanding units of each Portfolio (as
defined under "Investment Restrictions") or by a majority of the Trustees of the
Fund, and (b) by the vote of a majority of the Trustees of the Fund who are not
parties to the advisory agreement or "interested persons" (as such term is
defined in the 1940 Act) of any party thereto, (the "Disinterested Trustees"),

The advisory agreement will terminate automatically if assigned (as defined in
the 1940 Act) and is terminable at any time without penalty with respect to a
Portfolio by the Trustees of the Fund or by vote of a majority of the
outstanding units of the relevant Portfolio (as defined under "Investment
Restrictions") on 60 days' written notice to Goldman, Sachs & Co. and by
Goldman, Sachs & Co. on 60 days' written notice to the Fund.  The advisory
agreement may not be amended with respect to a Portfolio without the vote of a
majority of a Portfolio's outstanding units.
         
Expenses borne by each Portfolio include, without limitation, the fees payable
to Goldman, Sachs & Co. and CUFSLP, the fees and expenses of the Fund's
custodian, filing fees for the registration or qualification of Portfolio units

                            PORTFOLIO TRANSACTIONS

In connection with portfolio transactions for a Portfolio, which are generally
done at a net price without a broker's commission (i.e., a dealer is dealing
with a Portfolio as principal and receives compensation equal to the spread
between the dealer's cost for a given security and the resale price of such
security), the Portfolio's advisory agreement provides that Goldman, Sachs & Co.
shall attempt to obtain the best net price and the most favorable execution.  On
occasions when Goldman, Sachs & Co. deems the purchase or sale of a security to
be in the best interests of a Portfolio as well as its other customers
(including any other portfolio or other investment company or advisory account
for which Goldman, Sachs & Co. acts as investment adviser), the advisory
agreement provides that Goldman, Sachs & Co., to the extent permitted by
applicable laws and regulations, may aggregate the securities to be sold or
purchased for a Portfolio with those to be sold or purchased for such other
customers in order to obtain the best net price and most favorable execution.
In such event, allocation of the securities so purchased or sold, as well as the
expenses incurred in the transaction, will be made by Goldman, Sachs & Co. in
the manner it considers to be most equitable and consistent with its fiduciary
obligations to each Portfolio and such other customers.  In some instances, this
procedure may adversely affect the size of the position obtainable for a
Portfolio.  To the extent that the execution and price offered by more than one
dealer are believed to be comparable, the advisory agreement permits Goldman,
Sachs & Co., in its discretion, to purchase and sell portfolio securities to and
from dealers who provide the Fund with brokerage or research services.

During the fiscal year ended August 31, 1996, the Funds acquired and sold
securities issued by Lehman Brothers, Salomon Brothers Inc., Daiwa Securities
America, Inc., Chase Securities, Bear Stearns Companies, Inc., Morgan Stanley
Group, Inc., Swiss Bank Corp. and Union Bank, Nomura Securities International
and Smith Barney Shearson, Inc. At August 31, 1996, the Target Maturity
Portfolio (Feb 97) held the following amount of securities of its regular
broker/dealers, as defined in Rule 10b-1 under the 1940 Act, or their partners
($ in thousands):  Salomon Brothers Inc. -$4,239; Chase Securities - $2,556;
Bear Stearns Companies, Inc. -$1,200; Nomura Securities International - $5,810;
Smith Barney Shearson, Inc. - $1,200; and Swiss Bank - $4,692. The Target
Maturity Portfolio (May 97) held the following:  Salomon Brothers, Inc. -
$1,625; Chase Securities - $305; Bear Stearns Companies, Inc. - $405; Nomura
Securities International - $1,987; Smith Barney Shearson, Inc. - $405; and Swiss
Bank - $1,598.

ACTIVITIES OF GOLDMAN, SACHS & CO. AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED
- --------------------------------------------------------------------------------
BY GOLDMAN, SACHS & CO.  The involvement of Goldman, Sachs & Co. and its
- -----------------------                                                 
advisory affiliates in the management of, or interest in, other accounts and
other activities of Goldman, Sachs & Co. may present conflicts of interest with
respect to the Portfolios or impede their investment activities.

  Goldman, Sachs & Co. and its advisory affiliates have proprietary interests
in, and manage or advise, accounts or funds (including separate accounts and
other funds and collective investment vehicles) which have investment objectives
similar to those of the Portfolios and/or which engage in transactions in the
same types of securities and instruments as the Portfolios. Goldman, Sachs & Co.
and its affiliates are major participants in the fixed income markets, in each
case on a proprietary basis and for the accounts of customers. As such, Goldman,
Sachs & Co. and its affiliates are actively engaged in transactions in the same
securities and instruments in which the Portfolios invest.  Such activities
could affect the prices and availability of the securities and instruments in
which the Portfolios will invest, which could have an adverse impact on each
Portfolio's performance.  Such transactions, particularly in respect of
proprietary accounts or customer accounts other than those included in Goldman,
Sachs & Co. and its advisory affiliates' asset management activities, will be
executed independently of the Portfolios' transactions and thus at prices or
rates that may be more or less favorable.  When Goldman, Sachs & Co. or an
advisory affiliate seeks to purchase or sell the same assets for its managed
accounts, including a Portfolio, the assets actually purchased or sold may be
allocated among the accounts on a basis determined in its good faith discretion
to be equitable.  In some cases, this system may adversely affect the size or
the price of the assets purchased or sold for the Portfolios.

  From time to time, a Portfolios' activities may be restricted because of
regulatory restrictions applicable to Goldman, Sachs & Co. and its affiliates,
and/or their internal policies designed to comply with such restrictions.  As a
result, there may be periods, for example, when Goldman, Sachs & Co. will not
initiate or recommend certain types of transactions in certain securities or
instruments with respect to which Goldman, Sachs & Co. and/or its affiliates are
performing services or when position limits have been reached.

  In connection with its management of the Portfolios, GSAM may have access to
certain fundamental analysis and proprietary technical models developed by
Goldman, Sachs & Co. and other affiliates.  GSAM will not be under any
obligation, however, to effect transactions on behalf of the Portfolios in
accordance with such analysis and models.  In addition, neither Goldman, Sachs &
Co. nor any of its affiliates will have any obligation to      

                                      B-12
<PAGE>
 
    
make available any information regarding their proprietary activities or
strategies, or the activities or strategies used for other accounts managed by
them, for the benefit of the management of the Portfolios and it is not
anticipated that GSAM will have access to such information for the purpose of
managing the Portfolios.  The proprietary activities or portfolio strategies of
Goldman, Sachs & Co. and its affiliates or the activities or strategies used for
accounts managed by them or other customer accounts could conflict with the
transactions and strategies employed by GSAM in managing the Portfolios.

  The results of each Portfolio's investment activities may differ significantly
from the results achieved by Goldman, Sachs & Co. and its affiliates for their
proprietary accounts or accounts (including investment companies or collective
investment vehicles) managed or advised by them.  It is possible that Goldman,
Sachs & Co. and its affiliates and such other accounts will achieve investment
results which are substantially more or less favorable than the results achieved
by the Portfolios.  Moreover, it is possible that the Portfolios will sustain
losses during periods in which Goldman, Sachs & Co. and its affiliates achieve
significant profits on their trading for proprietary or other accounts.  The
opposite result is also possible.      

  An investment policy committee which may include partners of Goldman, Sachs &
Co. and its affiliates may develop general policies regarding Portfolio
activities, but will not be involved in the day-to-day management of the
Portfolios.  In such instances, those individuals may, as a result, obtain
information regarding the Portfolios' proposed investment activities which is
not generally available to the public.  In addition, by virtue of their
affiliation with Goldman, Sachs & Co., any such member of an investment policy
committee will have direct or indirect interests in the activities of Goldman,
Sachs & Co. and its affiliates in securities and investments similar to those in
which the Portfolios invest.
    
  In addition, certain principals and certain of the employees of GSAM are also
principals or employees of Goldman, Sachs & Co. or its affiliated entities.  As
a result, the performance by these principals and employees of their obligations
to such other entities may be a consideration of which investors in the
Portfolios should be aware.

  GSAM may enter into transactions and invest in instruments on behalf of a
Portfolio in which customers of Goldman, Sachs & Co. serve as the counterparty,
principal or issuer.  In such cases, such party's interests in the transaction
will be adverse to the interests of the Portfolios, and such party may have no
incentive to assure that the Portfolios obtain the best possible prices or terms
in connection with the transactions.  Goldman, Sachs & Co. and its affiliates
may also create, write or issue derivative      

                                      B-13
<PAGE>
 
    
instruments for customers of Goldman, Sachs & Co. or its affiliates, the
underlying securities or instruments of which may be those in which the
Portfolios invest or which may be based on the performance of a Portfolio.  The
Portfolios may, subject to applicable law, purchase investments which are the
subject of an underwriting or other distribution by Goldman, Sachs & Co. or its
affiliates and may also enter into transactions with other clients of Goldman,
Sachs & Co. or its affiliates where such other clients have interests adverse to
those of the Portfolios. At times, these activities may cause departments of the
Firm to give advice to clients that may cause these clients to take actions
adverse to the interests of the client.  To the extent affiliated transactions
are permitted, the Portfolios will deal with Goldman, Sachs & Co. and its
affiliates on an arm's-length basis.      

  Each Portfolio will be required to establish business relationships with its
counterparties based on the Portfolio's own credit standing.  Neither Goldman,
Sachs & Co. nor its affiliates will have any obligation to allow their credit to
be used in connection with a Portfolio's establishment of its business
relationships, nor is it expected that a Portfolio's counterparties will rely on
the credit of Goldman, Sachs & Co. or any of its affiliates in evaluating the
Portfolio's creditworthiness.
    
  It is possible that a Portfolio's holdings will include securities of entities
for which Goldman, Sachs & Co. performs investment banking services as well as
securities of entities in which Goldman, Sachs & Co. makes a market.  From time
to time, Goldman, Sachs & Co.'s activities may limit the Portfolios' flexibility
in purchases and sales of securities.  When Goldman, Sachs & Co. is engaged in
an underwriting or other distribution of securities of an entity, the GSAM may
be prohibited from purchasing or recommending the purchase of certain securities
of that entity for the Portfolios.      

TRANSFER AGENT

Under its transfer agency agreement, Goldman, Sachs & Co. serves as transfer
agent and dividend disbursing agent for each Portfolio.  Goldman, Sachs & Co.
has undertaken to (a) process and provide confirmations for purchase and
redemption transactions, (b) answer customer inquiries regarding the current
yield of, and certain other matters (e.g., account status information)
pertaining to, each Portfolio, (c) establish and maintain separate accounts with
respect to each unitholder, (d) provide periodic statements showing account
balances and (e) provide for the payment of dividends or distributions to
unitholders.

As compensation for the services rendered for a Portfolio as transfer agent,
Goldman, Sachs & Co. is also entitled to a fee of

                                      B-14
<PAGE>
 
$18 per year for each unitholder account plus reimbursement for certain
expenses.

For the periods indicated, the transfer agency fees incurred by each Portfolio
were as follows:

The administration agreement will remain in effect until March 31, 1997, and

CUSTODIAN

State Street Bank and Trust Company ("State Street"), P.O. Box 1713, Boston,
Massachusetts 02105, is the custodian of the Fund's portfolio securities and
cash.  State Street also maintains the Fund's accounting records.  The Northern
Trust Company ("Northern") has been retained by State Street to serve as its
agent in connection with certain wire receipts and transfers of funds.

AUDITORS
    
Arthur Andersen LLP, independent public accountants, One International Place,
Boston, Massachusetts, 02110, have been selected as auditors of the Fund.  In
addition to audit services, Arthur Andersen LLP, prepares the Fund's federal and
state tax returns, and provide consultation and assistance on accounting,
internal control and related matters.  The financial statements of the Target
Maturity Portfolio (Feb 97) and Target Maturity Portfolio (May 97), which are
incorporated by reference into this Additional Statement (under "Financial
Statements") from the Fund's annual report to unitholders for the fiscal year
ended August 31, 1996 (the "Annual Report"), and the data set forth under
"Financial Highlights" in the Prospectus have been audited by Arthur Andersen
LLP, as indicated in their report with respect thereto, which is incorporated by
reference in reliance upon the authority of said firm as experts in giving said
report.      


                              DESCRIPTION OF UNITS

As the Prospectus indicates, the Fund's Trust Agreement permits the Trustees to
issue an unlimited number of full and fractional units of beneficial interest of
one or more separate series representing interests in different investment
portfolios.  Under the terms of the Trust Agreement, each unit of each series
has a par value of $.001, represents an equal proportionate interest in a
particular investment portfolio with each other unit and is entitled to such
dividends out of the income belonging to such investment portfolio as are
declared by the Trustees.  All units of a Portfolio that are outstanding on its
Termination Date will be redeemed by the Fund at their net asset value, and each
Portfolio will be liquidated without further unitholder action.  Units do not
have preemptive or conversion rights.  Units when issued as described in the
Prospectus are fully paid and nonassessable, except as expressly set forth
below.

                                      B-20
<PAGE>
 
Any Trustee may be removed by the Fund's unitholders with or without cause at
any time by vote of those unitholders holding not less than two-thirds of the
units then outstanding, cast in person or by proxy at any meeting called for
that purpose.  The Trustees shall promptly call a meeting of unitholders for the
purpose of voting upon the question of removal of any Trustee when requested in
writing to do so by the holders of record of not less than 10% of the
outstanding units.

Whenever ten or more unitholders of record who have been such for at least six
months preceding the date of application, and who hold in the aggregate either
units having a net asset value of at least $25,000 or at least 1% of the
outstanding units, whichever is less, shall apply to the Trustees in writing
stating that they wish to communicate with other unitholders with a view to
obtaining signatures to a request for a unitholder meeting and include with such
application a form of communication and request which they wish to transmit, the
Trustees shall within five business days after receipt of such application
either (1) afford to such applicants access to a list of the names and addresses
of all unitholders as recorded on the books of the Fund or investment portfolio
involved; or (2) inform such applicants as to the approximate number of
unitholders of record, and the approximate cost of mailing to them the proposed
form of communication and request and, upon receipt of the material and the
expenses of mailing, shall promptly mail such materials to all unitholders
unless a majority of the Trustees believe that either such material contains
untrue statements of fact or omits to state facts necessary to make the
statements contained therein not misleading, or would be in violation of
applicable law.  The Trustees shall thereafter comply with any order entered by
the SEC and the requirements of the 1940 Act and the Securities Exchange Act of
1934.

In addition to Trustee election or removal as described in the Prospectus and as
further described herein, the Trust Agreement provides for unitholder voting
only (a) with respect to any contract as to which unitholder approval is
required by the 1940 Act, (b) with respect to any termination or reorganization
of the Fund or any investment portfolio to the extent and as provided in the
Trust Agreement (the liquidation of a Portfolio at the relevant Termination Date
is not subject to further unitholders action), (c) with respect to any amendment
of the Trust Agreement (other than amendments establishing and designating new
investment portfolios, abolishing investment portfolios, changing the name of
the Fund or the name of any investment portfolio, supplying any omission, curing
any ambiguity or curing, correcting or supplementing any provision thereof which
is internally inconsistent with any other provision thereof or which is
defective or inconsistent with the 1940 Act or with the requirements of the
Internal Revenue Code and applicable regulations for the Fund's obtaining the
most favorable treatment

                                      B-21
<PAGE>
 
thereunder available to regulated investment companies), which amendments
require approval by a majority of the units entitled to vote, (d) to the same
extent as the stockholders of a Massachusetts business corporation as to whether
or not a court action, proceeding or claim should or should not be brought or
maintained derivatively or as a class action on behalf of the Fund or the
unitholders, and (e) with respect to such additional matters relating to the
Fund as may be required by the 1940 Act, the Trust Agreement, the By-Laws of the
Fund, any registration of the Fund with the SEC or any State, or as the Trustees
may consider necessary or desirable.

Under Massachusetts law, there is a possibility that unitholders of a business
trust could, under certain circumstances, be held personally liable as partners
for the obligations of the Trust.  The Trust Agreement contains an express
disclaimer of unitholder liability for acts or obligations of the Fund and
requires that notice of such disclaimer be given in each agreement, obligation
or instrument entered into or executed by the Trustees or any officer.  The
Trust Agreement provides for indemnification out of Fund property of any
unitholder charged or held personally liable for the obligations or liabilities
of the Fund solely by reason of being or having been a unitholder of the Fund
and not because of such unitholder's acts or omissions or for some other reason.
The Trust Agreement also provides that the Fund shall, upon proper and timely
request, assume the defense of any charge made against any unitholder as such
for any obligation or liability of the Fund and satisfy any judgment thereon.
Thus, the risk of a unitholder's incurring financial loss on account of
unitholder liability is limited to circumstances in which the Fund itself would
be unable to meet its obligations.

The Trust Agreement provides that on any matter submitted to a vote of the
unitholders, all units entitled to vote shall be voted in the aggregate and not
by investment portfolio except that (a) as to any matter with respect to which a
separate vote of any investment portfolio is required by the 1940 Act or would
be required under the Massachusetts Business Corporation Law if the Fund were a
Massachusetts business corporation, such requirements as to a separate vote by
the investment portfolio shall apply in lieu of the aggregate voting as
described above, (b) in the event that the separate vote requirements referred
to in (a) above apply with respect to one or more investment portfolios, then
subject to (c) below, the units of all other investment portfolios shall vote as
a single investment portfolio, and (c) as to any matter which does not affect
the interest of a particular investment portfolio, only unitholders of the
affected investment portfolio shall be entitled to vote thereon.

Rule 18f-2 under the 1940 Act provides that any matter required by the
provisions of the 1940 Act or applicable state law, or

                                      B-22

otherwise, to be submitted to the holders of the outstanding voting securities
of an investment company such as the Fund shall not be deemed to have been
effectively acted upon unless approved by the holders of a majority of the
outstanding units of each investment portfolio affected by such matter.  Rule
18f-2 further provides that an investment portfolio shall be deemed to be
affected by a matter unless the interests of each investment portfolio in the
matter are identical or the matter does not affect any interest of the
investment portfolio.  Under the Rule, the approval of an investment advisory
agreement or any change in a fundamental investment policy would be effectively
acted upon with respect to an investment portfolio only if approved by a
majority of the outstanding units of such investment portfolio.  However, the
Rule also provides that the ratification of the appointment of independent
accountants, the approval of principal underwriting contracts and the election
of Trustees may be effectively acted upon by unitholders of the Fund voting
together in the aggregate without regard to a particular investment portfolio.

As of October 18, 1996, the outstanding units of the Target Maturity Portfolio
(Feb 97) and Target Maturity Portfolio (May 97) were 9,809,980.030 and
6,350,000.000, respectively.  To the Fund's knowledge, as of such date, the only

                  ADJUSTABLE AND FIXED RATE MORTGAGE LOANS AND
                          MORTGAGE-RELATED SECURITIES

THE NATURE OF ADJUSTABLE AND FIXED RATE MORTGAGE LOANS

The following is a general description of the adjustable and fixed rate mortgage
loans which may be expected to underlie the mortgage-related securities in which
each Portfolio invests.  The actual mortgage loans underlying any particular
issue of mortgage-related securities may differ materially from those described
below.

Adjustable Rate Mortgage Loans ("ARMs").  ARMs included in a mortgage pool will
generally provide for a fixed initial mortgage interest rate for a specified
period of time.  Thereafter, the interest rates (the "Mortgage Interest Rates")
may be subject to periodic adjustment based on changes in the applicable index
rate (the "Index Rate").  The adjusted rate would be equal to the Index Rate
plus a gross margin, which is a fixed percentage spread over the Index Rate
established for each ARM at the time of its origination.

Adjustable interest rates can cause payment increases that some mortgagors may
find difficult to make.  However, certain ARMs provide that the Mortgage
Interest Rate may not be adjusted to a rate above an applicable lifetime maximum
rate or below an applicable lifetime minimum rate for such ARM.  Certain ARMs
may also be subject to limitations on the maximum amount by which the Mortgage
Interest Rate may adjust for any single adjustment period (the "Maximum
Adjustment").  Other ARMs ("Negatively Amortizing ARMs") may provide instead or
as well for limitations on changes in the monthly payment on such ARMs.
Limitations on monthly payments can result in monthly payments which are more or
less than the amount necessary to amortize a Negatively Amortizing ARM by its
maturity at the Mortgage Interest Rate in effect in any particular month.  In
the event that a monthly payment is insufficient to pay the interest accruing on
a Negatively Amortizing ARM, any such excess interest is added to the principal
balance of the loan, causing negative amortization, and will be repaid through
future monthly payments.  It may take borrowers under Negatively Amortizing ARMs
longer periods of time to accumulate equity and may increase the likelihood of
default by such borrowers.  In the event that a monthly payment exceeds the sum
of the interest accrued at the applicable Mortgage Interest Rate and the
principal payment which would have been necessary to amortize the outstanding
principal balance over the remaining term of the loan, the excess (or
"accelerated amortization") further reduces the principal balance of the ARM.
Negatively Amortizing ARMs do not provide for the extension of their original
maturity to accommodate changes in their Mortgage Interest Rate.  As a result,
unless there is a periodic

                                      B-24
<PAGE>
 
recalculation of the payment amount (which there generally is), the final
payment may be substantially larger than the other payments.  These limitations
on periodic increases in interest rates and on changes in monthly payments
protect borrowers from unlimited interest rate and payment increases, but may
result in increased credit exposure and prepayment risks for lenders.

There are a number of indices which provide the basis for rate adjustments on
ARMs.  Commonly utilized indices include the one-year, three-year and five-year
constant maturity Treasury rates, the three-month Treasury Bill rate, the 180-
day Treasury Bill rate, rates of longer-term Treasury securities, the 11th
District Federal Home Loan Bank Cost of Funds, the National Median Cost of
Funds, the one-month, three-month, six-month, or one-year London Interbank
Offered Rate ("LIBOR"), the prime rate of a specific bank, or commercial paper
rates.  Some indices, such as the one-year constant maturity Treasury rate,
closely mirror changes in market interest rate levels.  Others, such as the 11th
District Federal Home Loan Bank Cost of Funds Index, tend to lag behind changes
in market rate levels and tend to be somewhat less volatile.  The degree of
volatility in the market value of a Portfolio and therefore in the net asset
value of a Portfolio's units will be influenced by the length of the interest
rate reset periods and the degree of volatility in the applicable indices.

Fixed Rate Mortgage Loans.  Generally, fixed rate mortgage loans eligible for
inclusion in a mortgage pool (the "Fixed Rate Mortgage Loans") will bear simple
interest at fixed annual rates and have original terms to maturity ranging from
5 to 40 years.  Fixed Rate Mortgage Loans generally provide for monthly payments
of principal and interest in substantially equal installments for the
contractual term of the mortgage note in sufficient amounts to amortize fully
principal by maturity, although certain Fixed Rate Mortgage Loans provide for a
large final "balloon" payment upon maturity.

Legal Considerations of Mortgage Loans.  The following is a discussion of
certain legal and regulatory aspects of the ARMs and Fixed Rate Mortgage Loans
expected to underlie the mortgage-related securities in which a Portfolio may
invest.  These regulations may impair the ability of a mortgage lender to
enforce its rights under the mortgage documents.  These regulations may
adversely affect a Portfolio's investments in both privately issued mortgage-
related securities and those issued or guaranteed by the U.S. Government, its
agencies or instrumentalities.

  1. Foreclosure.  A foreclosure of a defaulted mortgage loan may be delayed due
  to compliance with statutory notice or service of process provisions,
  difficulties in locating necessary parties or legal challenges to the
  mortgagee's right to foreclose.  Depending upon market conditions, the
  ultimate

                                      B-25
<PAGE>
 
  proceeds of the sale of foreclosed property may not equal the amounts owed on
  the mortgage loan.

  Further, courts in some cases have imposed general equitable principles upon
  foreclosure generally designed to relieve the borrower from the legal effect
  of default and have required lenders to undertake affirmative and expensive
  actions to determine the causes for the default and the likelihood of loan
  reinstatement.

  2. Rights of Redemption.  In some states, after foreclosure of a mortgage
  loan, the borrower and foreclosed junior lienors are given a statutory period
  in which to redeem the property, which right may diminish the mortgagee's
  ability to sell the property.

  3. Legislative Limitations.  In addition to anti-deficiency and related
  legislation, numerous other federal and state statutory provisions, including
  the federal bankruptcy laws and state laws affording relief to debtors, may
  interfere with or affect the ability of a secured mortgage lender to enforce
  its security interest.  For example, a bankruptcy court may grant the debtor a
  reasonable time to cure any default on a mortgage loan, including a payment
  default.  The court, in certain instances, may also reduce the monthly
  payments due under such mortgage loan, change the rate of interest, reduce the
  principal balance of the loan to the then-current appraised value of the
  related mortgage property, alter the mortgage loan repayment schedule, and
  grant priority to certain liens over the lien of the mortgage loan.  If a
  court relieves a borrower's obligation to repay amounts otherwise due on a
  mortgage loan, the mortgage loan servicer will not be required to advance such
  amounts, and any loss may be borne by the holders of securities backed by such
  loans.  In addition, numerous federal and state consumer protection laws
  impose penalties for failure to comply with specific requirements in
  connection with origination and servicing of mortgage loans.

  4. "Due on Sale" Provisions.  Fixed rate mortgage loans may contain a so
  called "due on sale" clause permitting acceleration of the maturity of the
  mortgage loan if the borrower transfers the property.  The Garn St. Germain
  Depository Institutions Act of 1982 sets forth nine specific instances in
  which no mortgage lender covered by that Act may exercise a "due on sale"
  clause upon a transfer of property.  The inability to enforce a "due on sale"
  clause or the lack of such a clause in a mortgage loan documents may result in
  a mortgage loan being assumed by a purchaser of the property that bears an
  interest rate below the current market rate.

  5. Usury Laws.  Some states prohibit charging interest on mortgage loans in
  excess of statutory limits.  If such limits

                                      B-26
<PAGE>
 
  are exceeded, substantial penalties may be incurred and, in some cases,
  enforceability of the obligation to pay principal and interest may be
  affected.


MORTGAGE-RELATED SECURITIES

Mortgage-related securities represent direct or indirect participations in, or
are collateralized by and payable from, mortgage loans secured by real property.

The investment characteristics of adjustable and fixed rate mortgage-related
securities differ from those of traditional fixed income securities.  The major
differences include the payment of interest and principal of mortgage-related
securities on a more frequent (usually monthly) schedule, and the possibility
that principal may be prepaid at any time due to prepayments on the underlying
mortgage loans.  These differences can result in significantly greater price and
yield volatility than is the case with traditional fixed income securities.  In
general, if a Portfolio purchases mortgage-related securities at a premium, a
faster than expected prepayment rate will reduce both the market value and the
yield to maturity from those which were anticipated.  A prepayment rate that is
slower than expected will have the opposite effect of increasing yield to
maturity and market value.  Conversely, if a Portfolio purchases mortgage-
related securities at a discount, faster than expected prepayments will
increase, while slower than expected prepayments will reduce, yield to maturity
and market value.

Prepayments on a pool of mortgage loans are influenced by changes in current
interest rates and a variety of economic, geographic, social and other factors
(such as changes in mortgagors' housing needs, job transfers, unemployment,
mortgagors' equity in the mortgage properties and servicing decisions).  The
timing and level of prepayments cannot be predicted.  Generally, however,
prepayments on mortgage loans will increase during a period of falling mortgage
interest rates and decrease during a period of rising mortgage interest rates.
Accordingly, the amounts of prepayments available for reinvestment by a
Portfolio are likely to be greater during a period of declining mortgage
interest rates.  If general interest rates decline, such prepayments are likely
to be reinvested at lower interest rates than the Portfolio was earning on the
mortgage-related securities that were prepaid.

The rate of interest on mortgage-related securities is normally lower than the
interest rates paid on the mortgages included in the underlying pool due to the
annual fees paid to the servicer of the mortgage pool for passing through
monthly payments to certificateholders and to any guarantor, such as GNMA, and
due to any yield retained by the issuer.  Actual yield to the holder may

                                      B-27
<PAGE>
 
vary from the coupon rate, even if adjustable, if the mortgage-related
securities are purchased or traded in the secondary market at a premium or
discount.  In addition, there is normally some delay between the time the issuer
receives mortgage payments from the servicer and the time the issuer makes the
payments on the mortgage-related securities and this delay reduces the effective
yield to the holder of such securities.

The issuers of certain mortgage-related securities may elect to have the pool of
mortgage loans (or indirect interests in mortgage loans) underlying the
securities treated as a real estate mortgage investment conduit ("REMIC"), which
are subject to special federal income tax rules.  A description of the types of
mortgage-related securities in which a Portfolio may invest is provided below.
The descriptions are general and summary in nature, and do not detail every
possible variation of the types of securities that are permissible for a
Portfolio.

1.  Private Mortgage Pass-Through Securities

General Characteristics.  Privately issued mortgage pass-through securities
("Private Mortgage Pass-Throughs") represent participation interests in pools of
mortgage loans conveyed to the issuing trust and generally serviced for the
trust by the originator.  For federal income tax purposes, such trusts are
generally treated as grantor trusts or REMICs and, in either case, are generally
not subject to any significant amount of federal income tax at the entity level.
Private Mortgage Pass-Throughs (whether fixed or adjustable rate) provide for
monthly payments that are a "pass-through" of the monthly interest and principal
payments (including any prepayments) made by the individual borrowers on the
pooled mortgage loans, net of any fees or other amounts paid to any guarantor,
administrator and/or servicer of the underlying mortgage loans.

Each mortgage pool underlying Private Mortgage Pass-Throughs will consist of
mortgage loans evidenced by promissory notes secured by first mortgages or first
deeds of trust or other similar security instruments creating a first lien on
the mortgaged properties (the "Mortgaged Properties").  The Mortgaged Properties
may consist of residential properties upon which is located detached individual
dwelling units, individual condominium units, townhouses, duplexes, triplexes,
fourplexes, rowhouses, manufactured homes, individual units in planned unit
developments and other attached dwelling units, vacation homes, second homes,
residential investment properties, multi-family units or properties with mixed
residential and commercial uses.  A trust fund with respect to which a REMIC
election has been made may include regular interests in other REMICs which in
turn will ultimately evidence interests in mortgage loans.

                                      B-28
<PAGE>
 
The seller or servicer of the underlying mortgage obligations will generally
make representations and warranties to certificateholders as to certain
characteristics of the mortgage loans and as to the accuracy of certain
information furnished to the trustee in respect of each such mortgage loan.
Upon a breach of any representation or warranty that materially and adversely
affects the interests of the related certificateholders in a mortgage loan, the
seller or servicer generally will be obligated either to cure the breach in all
material respects, to repurchase the mortgage loan or, if the related agreement
so provides, to substitute in its place a mortgage loan pursuant to the
conditions set forth therein.  Such a repurchase or substitution obligation
generally constitutes the sole remedy available to the related
certificateholders or the trustee for a material breach of any such
representation or warranty by the seller or servicer.

Description of Certificates.  Private Mortgage Pass-Throughs may be issued in
one or more classes of senior certificates and one or more classes of
subordinate certificates.  Each such class may bear a different pass-through
rate.  Generally, each certificate will evidence the specified interest of the
holder thereof in the payments of principal or interest or both in respect of
the mortgage pool comprising part of the trust fund for such certificates.

Any class of certificates may also be divided into subclasses entitled to
varying amounts of principal and interest.  If a REMIC election has been made,
certificates of such subclasses may be entitled to payments on the basis of a
stated principal balance and stated interest rate, and payments among different
subclasses may be made on a sequential, concurrent, pro rata or disproportionate
                                                    --------                    
basis, or any combination thereof.  The stated interest rate on any such
subclass of certificates may be a fixed rate or one which varies in direct or
inverse relationship to an objective interest index.  Subclasses of certificates
as to which a REMIC election has been made may have the features and structures
described below under the caption "Multiple Class Pass-Through Securities and
Collateralized Mortgage Obligations."

Generally, each registered holder of a certificate will be entitled to receive
its pro rata share of monthly distributions of all or a portion of principal of
    --------                                                                   
the underlying mortgage loans or of interest on the principal balances thereof,
which accrues at the applicable mortgage pass-through rate, or both.  The
difference between the mortgage interest rate and the related mortgage pass-
through rate (less the amount, if any, of retained yield) with respect to each
mortgage loan will generally be paid to the servicer as a servicing fee. Since
certain adjustable rate mortgage loans included in a mortgage pool may provide
for deferred interest (i.e., negative amortization), the amount of interest
actually paid by a mortgagor in any month may be less than the amount of
interest accrued on the outstanding principal

                                      B-29
<PAGE>
 
balance of the related mortgage loan during the relevant period at the
applicable mortgage interest rate.  In such event, the amount of interest that
is treated as deferred interest will be added to the principal balance of the
related mortgage loan and will be distributed pro rata to certificateholders as
                                              --------                         
principal of such mortgage loan when paid by the mortgagor in subsequent monthly
payments or at maturity.

Ratings.  The ratings assigned by an NRSRO to Private Mortgage Pass-Throughs
address the likelihood of the receipt of all distributions on the underlying
mortgage loans by the related certificateholders under the agreements pursuant
to which such certificates are issued.  A rating agency's ratings take into
consideration the credit quality of the related mortgage pool, including any
credit support providers, structural and legal aspects associated with such
certificates, and the extent to which the payment stream on such mortgage pool
is adequate to make payments required by such certificates.  A rating agency's
ratings on such certificates do not, however, constitute a statement regarding
frequency of prepayments on the related mortgage loans.  In addition, the rating
assigned by a rating agency to a certificate does not address the remote
possibility that, in the event of the insolvency of the issuer of certificates
where a subordinated interest was retained, the issuance and sale of the senior
certificates may be recharacterized as a financing and, as a result of such
recharacterization, payments on such certificates may be affected.

Types of Credit Support.  Mortgage pools created by non-governmental issuers
generally offer a higher yield than government and government-related pools
because of the absence of direct or indirect government or agency payment
guarantees.  To lessen the effect of failures by obligors on underlying assets
to make payments, Private Mortgage Pass-Throughs may contain elements of credit
support.  Such credit support falls into two classes:  liquidity protection and
protection against ultimate default by an obligor on the underlying mortgages.
Liquidity protection refers to the provision of advances, generally by the
entity administering the pools of mortgages, the provision of a reserve fund, or
a combination thereof, to ensure, subject to certain limitations, that scheduled
payments on the underlying pool are made in a timely fashion.  Protection
against ultimate default ensures ultimate payment of the obligations on at least
a portion of the mortgages in the pool.  Such protection may be provided through
guarantees, insurance policies or letters of credit obtained from third parties,
through various means of structuring the transaction or through a combination of
such approaches.

In addition, one or more classes of certificates of Private Mortgage Pass-
Throughs may be subordinate certificates which

                                      B-30
<PAGE>
 
provide that the rights of the subordinate certificateholders to receive any or
a specified portion of distributions with respect to the underlying mortgage
loans may be subordinated to the rights of the senior certificateholders.  If so
structured, the subordination feature may be enhanced by distributing to the
senior certificateholders on certain distribution dates, as payment of
principal, a specified percentage (which generally declines over time) of all
principal prepayments received during the preceding prepayment period ("shifting
interest credit enhancement").  This will have the effect of accelerating the
amortization of the senior certificates while increasing the interest in the
trust fund evidenced by the subordinate certificates.  Increasing the interest
of the subordinate certificates relative to that of the senior certificates is
intended to preserve the availability of the subordination provided by the
subordinate certificates.  In addition, because the senior certificateholders in
a shifting interest credit enhancement structure are entitled to receive a
percentage of principal prepayments which is greater than their proportionate
interest in the trust fund, the rate of principal prepayments on the mortgage
loans will have an even greater effect on the rate of principal payments and the
amount of interest payments on, and the yield to maturity of, the senior
certificates.

In addition to providing for a preferential right of the senior
certificateholders to receive current distributions from the mortgage pool, a
reserve fund may be established relating to such certificates (the "Reserve
Fund").  The Reserve Fund may be created with an initial cash deposit by the
originator or servicer and augmented by the retention of distributions otherwise
available to the subordinate certificateholders or by excess servicing fees
until the Reserve Fund reaches a specified amount.

The subordination feature, and any Reserve Fund, are intended to enhance the
likelihood of timely receipt by senior certificateholders of the full amount of
scheduled monthly payments of principal and interest due them and will protect
the senior certificateholders against certain losses; however, in certain
circumstances the Reserve Fund could be depleted and temporary shortfalls could
result.  In the event the Reserve Fund is depleted before the subordinated
amount is reduced to zero, senior certificateholders will nevertheless have a
preferential right to receive current distributions from the mortgage pool to
the extent of the then outstanding subordinated amount.  Unless otherwise
specified, until the subordinated amount is reduced to zero, on any distribution
date any amount otherwise distributable to the subordinate certificates or, to
the extent specified, in the Reserve Fund will generally be used to offset the
amount of any losses realized with respect to the mortgage loans ("Realized
Losses").  Realized Losses remaining after application of such amounts will
generally be applied to reduce the ownership

                                      B-31
<PAGE>
 
interest of the subordinate certificates in the mortgage pool.  If the
subordinated amount has been reduced to zero, Realized Losses generally will be
allocated pro rata among all certificateholders in proportion to their
          --------                                                    
respective outstanding interests in the mortgage pool.

As an alternative, or in addition to the credit enhancement afforded by
subordination, credit enhancement for Private Mortgage Pass-Throughs may be
provided by mortgage insurance, by the deposit of cash, certificates of deposit,
letters of credit, a limited guaranty or by such other methods as are acceptable
to a rating agency.  In certain circumstances, such as where credit enhancement
is provided by insurance, guarantees or a letter of credit, the security is
subject to credit risk because of its exposure to an external credit enhancement
provider.

Voluntary Advances.  Generally, in the event of delinquencies in payments on the
mortgage loans underlying the Private Mortgage Pass-Throughs, the servicer
agrees to make advances of cash for the benefit of certificateholders, but only
to the extent that it determines such voluntary advances will be recoverable
from future payments and collections on the mortgage loans or otherwise.

Optional Termination.  Generally, the servicer may, at its option with respect
to any certificates, repurchase all of the underlying mortgage loans remaining
outstanding at such time as the aggregate outstanding principal balance of such
mortgage loans is less than a specified percentage (generally 5-10%) of the
aggregate outstanding principal balance of the mortgage loans as of the cut-off
date specified with respect to such series.

2. Government Mortgage-Related Securities

As stated in the Prospectus, certain mortgage-related securities acquired by a
Portfolio will be issued or guaranteed by the U.S. Government or one of its
agencies, instrumentalities or sponsored enterprises, including but not limited
to the Government National Mortgage Association ("GNMA"), the Federal National
Mortgage Association ("FNMA") and the Federal Home Loan Mortgage Corporation
("FHLMC") ("Government Mortgage-Related Securities").  GNMA securities are
backed by the full faith and credit of the U.S. Government, which means that the
U.S. Government guarantees that the interest and principal will be paid when
due.  FNMA securities and FHLMC securities are not backed by the full faith and
credit of the U.S. Government; however, because of their ability to borrow from
the U.S. Treasury, they are generally viewed by the market as high quality
securities with minimal credit risks.  There are several types of these
guaranteed mortgage-related securities currently available, including guaranteed
mortgage pass-through certificates and multiple-class securities, which include
guaranteed REMIC pass-through

                                      B-32
<PAGE>
 
certificates and stripped mortgage-backed securities.  A Portfolio will be
permitted to invest in other types of Government Mortgage-Related Securities
that may be available in the future to the extent such investment is consistent
with its investment policies and objective.

GNMA Certificates.  GNMA is a wholly-owned corporate instrumentality of the
United States.  GNMA is authorized to guarantee the timely payment of the
principal of and interest on certificates that are based on and backed by a pool
of mortgage loans insured by the Federal Housing Administration ("FHA Loans"),
or guaranteed by the Veterans Administration ("VA Loans"), or by pools of other
eligible mortgage loans.  In order to meet its obligations under any guaranty,
GNMA is authorized to borrow from the United States Treasury in an unlimited
amount.

FNMA Certificates.  FNMA is a stockholder-owned corporation chartered under an
act of the United States Congress.  Each FNMA Certificate is issued and
guaranteed by and represents an undivided interest in a pool of mortgage loans
(a "Pool") formed by FNMA.  Each Pool consists of residential mortgage loans
("Mortgage Loans") either previously owned by FNMA or purchased by it in
connection with the formation of the Pool.  The Mortgage Loans may be either
private Mortgage Loans (i.e., not insured or guaranteed by any U.S. Government
agency) or Mortgage Loans that are either insured by the Federal Housing
Administration ("FHA") or guaranteed by the Veterans Administration ("VA").  The
lenders originating and servicing the Mortgage Loans are subject to certain
eligibility requirements established by FNMA.

FNMA has certain contractual responsibilities.  With respect to each Pool, FNMA
is obligated to distribute scheduled monthly installments of principal and
interest after FNMA's servicing and guaranty fee, whether or not received, to
Certificate holders.  FNMA is also obligated to distribute to holders of
Certificates an amount equal to the full principal balance of any foreclosed
Mortgage Loan, whether or not such principal balance is actually recovered.  The
obligations of FNMA under its guaranty of the FNMA Certificates are obligations
solely of FNMA.

FHLMC Certificates.  FHLMC is a corporate instrumentality of the United States.
The principal activity of FHLMC currently is the purchase of first lien,
conventional, residential mortgage loans and participation interests in such
mortgage loans and their resale in the form of mortgage securities, primarily
FHLMC Certificates.  A FHLMC Certificate represents a pro rata interest in a
group of mortgage loans or participations in mortgage loans (a "FHLMC
Certificate group") purchased by FHLMC.

FHLMC guarantees to each registered holder of a FHLMC Certificate the timely
payment of interest at the rate provided for by such Certificate (whether or not
received on the underlying loans).

                                      B-33
<PAGE>
 
FHLMC also guarantees to each registered Certificate holder ultimate collection
of all principal of the related mortgage loans, without any offset or deduction,
but does not, generally, guarantee the timely payment of scheduled principal.
The obligations of FHLMC under its guaranty of FHLMC Certificates are
obligations solely of FHLMC.

The mortgage loans underlying the FHLMC Certificates will consist of adjustable
rate or fixed rate mortgage loans with original terms of maturity of between ten
and thirty years.  Substantially all of these mortgage loans are secured by
first liens on one- to four-family residential properties or multi-family
projects.  Each mortgage loan must meet the applicable standards set forth in
the law creating FHLMC.  A FHLMC Certificate group may include whole loans,
participation interests in whole loans and undivided interests in whole loans
and participations comprising another FHLMC Certificate group.

3.  Multiple Class Pass-Through Securities and
    Collateralized Mortgage Obligations

As stated, a Portfolio may invest in multiple class mortgage-related securities,
including collateralized mortgage obligations and REMIC pass-through or
participation certificates (collectively, "CMOs").  These multiple class
mortgage-related securities may be issued by U.S. Government agencies,
instrumentalities or sponsored enterprises, including FNMA and FHLMC, or by
trusts formed by private originators of, or investors in, mortgage loans.  In
general, CMOs represent direct ownership interests in a pool of mortgage loans
or mortgage pass-through securities (the "Mortgage Assets"), the payments on
which are used to make payments on the CMOs.  Investors may purchase beneficial
interests in CMOs, which are known as "regular" interests or "residual"
interests.  Each Portfolio does not intend to purchase residual interests.

Each class of CMOs, often referred to as a "tranche," is issued at a specific
adjustable or fixed interest rate and is scheduled to be fully retired no later
than its final distribution date.  Principal prepayments on the Mortgage Assets
underlying the CMOs may cause some or all of the classes of CMOs to be retired
substantially earlier than their final distribution dates.  Generally, interest
is paid or accrues on all classes of CMOs on a monthly basis.

The principal of and interest on the Mortgage Assets may be allocated among the
several classes of a CMO in various ways.  In certain structures (known as
"sequential pay" CMOs), payments of principal, including any principal
prepayments, on the Mortgage Assets generally are applied to the classes of CMOs
in the order of their respective final scheduled distribution dates.  Thus, no
payment of principal will be made on any class of sequential pay

                                      B-34
<PAGE>
 
CMOs until all other classes having an earlier final scheduled distribution date
have been paid in full.

Additional structures of CMOs include, among others, "parallel pay" CMOs.
Parallel pay CMOs are those which are structured to apply principal payments and
prepayments of the Mortgage Assets to two or more classes concurrently on a
proportionate or disproportionate basis.  These simultaneous payments are taken
into account in calculating the final scheduled distribution date of each class.

A wide variety of CMOs may be issued in the parallel pay or sequential pay
structures.  These securities include accrual certificates (also known as "Z-
Bonds"), which do not accrue interest at a specified rate until all other
certificates having an earlier final scheduled distribution date have been
retired and such "Z-Bonds" are converted thereafter to an interest-paying
security, and planned amortization class ("PAC") certificates, which are
parallel pay CMOs which generally require that specified amounts of principal be
applied on each payment date to one or more classes of a CMO (the "PAC
Certificates"), even though all other principal payments and prepayments of the
Mortgage Assets are then required to be applied to one or more other classes of
the Certificates.  The scheduled principal payments for the PAC Certificates
generally have the highest priority on each payment date after interest due has
been paid to all classes entitled to receive interest currently.  Shortfalls, if
any, are added to the amount payable on the next payment date.  The PAC
Certificate payment schedule is taken into account in calculating the final
scheduled distribution date of each class of PAC.  In order to create PAC
tranches, one or more tranches generally must be created that absorb most of the
prepayment volatility in the underlying Mortgage Assets.  These tranches tend to
have market prices and yields that are much more volatile than the PAC classes.

FNMA CMOs are issued and guaranteed as to timely distribution of principal and
interest by FNMA.  That is to say, FNMA will be obligated to distribute on a
timely basis to holders of FNMA CMO certificates required installments of
principal and interest and to distribute the principal balance of each class of
a CMO in full, whether or not sufficient funds are otherwise available.
    
For FHLMC CMOs, FHLMC guarantees the timely payment of interest, and also
guarantees the payment of principal as payments are required to be made on the
underlying mortgage participation certificates ("Pcs").  Pcs represent undivided
interests in specified level payment, residential mortgages or participations
therein purchased by FHLMC and placed in a Pc pool.  With respect to principal
payments on Pcs, FHLMC generally guarantees ultimate collection of all principal
of the related mortgage loans without      

                                      B-35
<PAGE>
 
    
offset or deduction.  FHLMC also guarantees timely payment of principal on
certain Pcs, referred to as "Gold Pcs."      


                           OTHER INVESTMENT PRACTICES

LENDING OF PORTFOLIO SECURITIES
    
The Portfolios may seek to increase its income by lending portfolio securities
to institutions, such as banks and broker-dealers. These loans will be
continuously collateralized by cash, cash equivalents of Government Securities
in an amount at least equal to the market value of the securities loaned. Each
Portfolio will have the right to call a loan and obtain the securities loaned at
any time on a five days notice. For the duration of a loan, each Portfolio will
continue to receive the equivalent of the interest paid by the issuer on the
securities loaned and will also receive compensation from investment of the
collateral. Each Portfolio will not have the right to vote any securities having
voting rights during the existence of the loan, but each Portfolio will call the
loan in anticipation of an important vote to be taken among holders of the
securities or the giving or withholding of its consent on a material matter
affecting the investment. As with other extensions of credit, there are risks of
delay in recovering, or even loss of rights in, the collateral should the
borrower of the securities fail financially. However, the loans will be made
only to firms deemed by Goldman, Sachs & Co. to be of good standing, and when,
in its judgment, the consideration which can be earned currently from securities
loans of this type justifies the attendant risk. If Goldman, Sachs & Co.
determines to make securities loans, it is expected that during the current
fiscal year, that such loans will not exceed 5% of a Portfolio's net assets.

INVERSE FLOATING RATE SECURITIES

  The Government Securities Portfolio and the Mortgage Securities Portfolio may,
to the extent permitted by the National Credit Union Administration ("NCUA"), in
leveraged inverse floating rate debt instruments ("inverse floaters"). The
interest rate on an inverse floater resets in the opposite direction from the
market rate of interest to which the inverse floater is indexed. An inverse
floater may be considered to be leveraged to the extent that its interest rate
varies by a magnitude that exceeds the magnitude of the change in the index rate
of interest. The higher degree of leverage inherent in inverse floaters is
associated with greater volatility in their market values. Accordingly, the
duration of an inverse floater may exceed its stated final maturity. Certain
inverse floaters may be deemed to be illiquid securities for purposes of a
Portfolio's 15% limitation on investments in such securities.      

                                      B-36
<PAGE>
 
                            INVESTMENT RESTRICTIONS
    
As the Prospectus states, a Portfolio may only invest in obligations authorized
under the Federal Credit Union Act.  This restriction may not be changed without
the approval of the holders of a majority of the outstanding units of a
Portfolio as described below.  In addition, the Fund has adopted the following
enumerated fundamental investment restrictions, none of which may be changed
without the approval of the holders of a majority of the outstanding units of
the Portfolio as described below.  A Portfolio may not:      

  A. Invest in the instruments of issuers conducting their principal business
  activity in the same industry if immediately after such investment the value
  of the Portfolio's investments in such industry would exceed 25% of the value
  of its total assets; provided that there is no limitation with respect to or
  arising out of investments in obligations issued or guaranteed by the U.S.
  Government or its agencies or instrumentalities or repurchase agreements by
  the Portfolio of securities collateralized by such obligations; and provided
  further that during normal market conditions each Portfolio intends to invest
  at least 25% of the value of its total assets in mortgage-related securities.

  B. Invest in the instruments of any one issuer, other than the U.S.
  Government, its agencies or instrumentalities, if immediately after such
  investment, more than 5% of the value of the Portfolio's total assets would be
  invested in the instruments of such issuer, except that (a) up to 25% of the
  value of the total assets of the Portfolio may be invested without regard to
  such 5% limitation and (b) such 5% limitation shall not apply to repurchase
  agreements collateralized by obligations of the U.S. Government, its agencies
  or instrumentalities.

  C. Make loans, except through (a) the purchase of debt obligations in
  accordance with the Portfolio's investment objective and policies, (b)
  repurchase agreements with banks, brokers, dealers and other financial
  institutions in accordance with the investment objectives of the Portfolio,
  (c) the lending of federal funds to qualified financial institutions in
  accordance with the investment objectives of the Portfolio and (d) the lending
  of securities in accordance with the investment objective of the Portfolio.

  D. Borrow money, except for temporary or short-term purposes, provided that
  the Portfolio maintains asset coverage of 300% for all such borrowing.

  E. Mortgage, pledge or hypothecate any assets except to secure permitted
  borrowings.

                                      B-37
<PAGE>
 
  F. Purchase or sell real estate, but this restriction shall not prevent the
  Portfolio from investing directly or indirectly in portfolio instruments
  secured by real estate or interests therein or issued by companies which
  invest in real estate or interests therein.

  G. Purchase or sell commodities or commodity contracts.

  H. Purchase any voting securities except of investment companies (solely to
  the extent permitted by the 1940 Act) and as otherwise consistent with its
  investment objective and policies, or invest in companies for the purpose of
  exercising control or management.  Subject to certain exceptions, the 1940 Act
  contains a prohibition against each Portfolio investing more than 5% of its
  total assets in the securities of another investment company, investing more
  than 10% of its assets in securities of such investment company and all other
  investment companies or purchasing more than 3% of the total outstanding
  voting stock of another investment company.

  I. Act as an underwriter of securities.

  J. Issue senior securities as defined in the 1940 Act except insofar as the
  Portfolio may be deemed to have issued a senior security by reason of (a)
  borrowing of money to the extent permitted herein, or (b) purchasing
  securities on a when-issued or delayed delivery basis, or (c) entering into a
  mortgage dollar roll.

  K. Purchase any security on margin (except for delayed delivery or when-issued
  transactions or such short-term credits as are necessary for the clearance of
  transactions).

  L. Make short sales of securities or maintain a short position.

  M. Write, purchase or sell puts, calls or combinations thereof.
         
For purposes of the foregoing limitations, any limitation which involves a
maximum percentage shall not be considered violated unless an excess over the
percentage occurs immediately after, and is caused by, an acquisition or
encumbrance of securities or assets of, or borrowings by, a Portfolio.  In
addition, securities held in escrow or separate accounts in connection with a
Portfolio's investment practices are not deemed to be pledged for purposes of
the foregoing limitations.

Borrowings by a Portfolio (if any) are not for investment leverage purposes but
are solely for temporary or short-term purposes or to facilitate management of
the Portfolio by enabling the Fund to meet redemption requests when the
liquidation of

                                      B-38
<PAGE>
 
portfolio instruments is deemed to be disadvantageous or not possible.  If due
to market fluctuations or other reasons the total assets of a Portfolio fall
below 300% of its borrowings, the Fund will promptly reduce the borrowings of
such Portfolio in accordance with the 1940 Act.  No purchases of securities will
be made if such borrowings exceed 5% of the value of a Portfolio's assets.
Mortgage dollar rolls that are not accounted for as financings shall not
constitute borrowings.

The prohibition against short sales and short positions does not include
transactions sometimes referred to as "short sales against the box" where a
Portfolio contemporaneously owns or has the right to obtain at no added cost
securities identical to those sold short.
    
As used in the Prospectus and this Additional Statement with respect to a change
in investment objective or fundamental investment restrictions, the approval of
an investment advisory agreement or the approval of a distribution agreement,
the term "majority of the outstanding units" of either the Fund or a Portfolio
means the vote of the lesser of (i) 67% or more of the units of the Fund or a
Portfolio present at a meeting, if the holders of more than 50% of the
outstanding units of the Fund or Portfolio are present or represented by proxy,
or (ii) more than 50% of the outstanding units of the Fund or a Portfolio.      


                     CALCULATION OF PERFORMANCE QUOTATIONS

From time to time, the yield, the distribution rate and the total return of a
Portfolio may be quoted in advertisements or communications to unitholders.
These advertisements and communications may be part of marketing activities
conducted by either or both of the Fund's co-distributors on behalf of a
Portfolio. Performance figures are calculated in the following manner:

Yield Calculations.  The yield of a Portfolio is calculated by dividing the net
investment income per unit (as described below) earned by a Portfolio during a
30-day period by the maximum offering price per unit on the last day of the
period and annualizing the result on a semi-annual basis by adding one to the
quotient, raising the sum to the power of six, subtracting one from the result
and then doubling the difference.  A Portfolio's net investment income per unit
earned during the period is based on the average daily number of units
outstanding during the period entitled to receive dividends and includes
dividends and interest earned during the period minus expenses accrued for the
period, net of reimbursements.  This calculation can be expressed as follows:

                                      B-39
<PAGE>
 
               Yield = 2[[((a-b)/cd) + 1]to the 6th power) - 1]

Where:

a =  dividends and interest earned during the period.

b =  expenses accrued for the period.

c =  the average daily number of units outstanding during the period that were
     entitled to receive dividends.

d =  maximum offering price per unit on the last day of the period.

Except as noted below, interest earned on debt obligations held by a Portfolio
is calculated by computing the yield to maturity of each obligation held by a
Portfolio based on the market value of the obligation (including actual accrued
interest) at the close of business on the last business day of each month, or,
with respect to obligations purchased during the month, the purchase price (plus
actual accrued interest) and dividing the result by 360 and multiplying the
quotient by the market value of the obligation (including actual accrued
interest) in order to determine the interest income on the obligation for each
day of the subsequent month that the obligation is held by a Portfolio.  The
maturity of an obligation with a call provision is the next call date on which
the obligation reasonably may be expected to be called or, if none, the maturity
date.  With respect to debt obligations purchased at a discount or premium, the
formula generally calls for amortization of the discount or premium.  The
amortization schedule will be adjusted monthly to reflect changes in the market
values of such debt obligations.

With respect to mortgage-related obligations which are expected to be subject to
monthly payments of principal and interest ("pay downs"), (a) gain or loss
attributable to actual monthly pay downs is accounted for as an increase or
decrease to interest income during the period; and (b) a Portfolio may elect
either (i) to amortize the discount and premium on the remaining security, based
on the cost of the security, to the weighted average maturity date, if such
information is available, or to the remaining term of the security, if any, if
the weighted average maturity date is not available, or (ii) not to amortize
discount or premium on the remaining security.

Distribution Rate Calculations.  The distribution rate for a specified period is
calculated by dividing the total distribution per share by the maximum offering
price on the last day of the period and then annualizing such amount.

Total Return Calculations.  A Portfolio computes its average annual total return
by determining the average annual compounded

                                      B-40
<PAGE>
 
rates of return during specified periods that equate the initial amount invested
to the ending redeemable value of such investment.  This is done by dividing the
ending redeemable value of a hypothetical $1,000 initial payment by $1,000 and
raising the quotient to a power equal to one divided by the number of years (or
fractional portion thereof) covered by the computation and subtracting one from
the result.  This calculation can be expressed as follows:


                            T = [ERV to the 1 divided by nth power] - 1
                                 ---
                                 P

Where:

T  =  average annual total return.
 
ERV  =  ending redeemable value at the end of the period
        covered by the computation of a hypothetical $1,000
        payment made at the beginning of the period.
 
P  =  hypothetical initial payment of $1,000.
 
n  =  period covered by the computation, expressed in terms of
      years.

Each Portfolio computes its cumulative total return by determining the
cumulative rate of return during a specified period that likewise equates the
initial amount invested to the ending redeemable value of such investment.  The
formula for calculating cumulative total return is as follows:

                                T = (ERV/P) - 1

Under the methods prescribed by the SEC, standardized calculations of average
annual total return assume the reinvestment of all dividends and capital gain
distributions on the reinvestment dates during the period (although a Portfolio
may also publish non-standardized calculations without this assumption).
Calculations of cumulative total return also assume the reinvestment of all
dividends and capital gains distributions on the reinvestment date during the
period.  The ending redeemable value (variable "ERV" in each formula) is
determined by assuming complete redemption of the hypothetical investment and
the deduction of all nonrecurring charges (such as a Portfolio's redemption fee
for early withdrawal) at the end of the period covered by the computations
(although, again, a Portfolio may also publish non-standardized calculations
without this deduction).  Year-to-year total return is calculated in a similar
manner.

The composition of the securities in such indices and the characteristics of
such benchmark investments are not identical to, and in some cases are very
different from, those of a Portfolio.  These indices and averages are generally
unmanaged and the items included in the calculations of such indices and
averages may not be identical to the formulas used by a Portfolio to calculate
its performance figures.

From time to time advertisements or communications to unitholders may summarize
the substance of information contained in shareholder reports (including the
investment composition of the Portfolios), as well as the views of Goldman,
Sachs & Co. as to current market, economic, trade and interest rate trends,
legislative, regulatory and monetary developments, investment strategies and
related matters believed to be of relevance to the Portfolios (such as the
supply and demand of mortgage-related securities and the relative performance of
different types of mortgage loans and mortgage-related securities as affected by
prepayment rates and other factors).

In addition, from time to time, advertisements or information may include a
discussion of asset allocation models developed by GSAM and/or its affiliates,
certain attributes or benefits to be derived from asset allocation strategies
and the Goldman Sachs mutual funds that may be offered as investment options for
the strategic asset allocations.  Such advertisements and information may also

                      DESCRIPTION OF SECURITIES RATINGS*      

A. LONG-TERM RATINGS

MOODY'S INVESTORS SERVICE, INC.

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 with Aaa securities.

Moody's applies numerical modifiers l, 2, and 3 in the Aa category.  The
modifier 1 indicates that the company ranks in the higher end of the Aa
category; the modifier 2 indicates a mid-range ranking; and the modifier 3
indicates that the issue ranks in the lower end of the Aa category.

STANDARD & POOR'S RATINGS GROUP

AAA:  Bonds rated AAA are highest grade debt obligations.  This rating indicates
an extremely strong capacity to pay interest and repay principal.

AA:  Capacity to pay interest and repay principal is very strong, and differs
from AAA issues only in small degree.

Plus (+) or Minus (-):  The AA rating may be modified by the addition of a plus
or minus sign to show relative standing within the AA category.
________________________
    
*    The ratings systems described herein are believed to be the most recent
ratings systems available from Moody's Investors Service, Inc. and Standard &
Poor's Ratings Group at the date of this Additional Statement for the securities
listed.  Ratings are generally given to securities at the time of issuance.
While the rating agencies may from time to time revise such ratings, they
undertake no obligation to do so, and the ratings indicated do not necessarily
represent ratings which will be given to these securities throughout the period
they are held by a Portfolio.     

                                      B-46
<PAGE>
 
r:   A rating may be modified by the addition of an "r" rating to highlight
derivative, hybrid and certain other obligations that Standard & Poor's believes
may experience high volatility or high variability in expected returns due to
non-credit risks.  The absence of an "r" symbol should not be taken as an
indication that an obligation will exhibit no volatility or variability in total
return.


Duff & Phelps, Inc.

AAA:  Long-term fixed income securities which are rated AAA are judged to be of
the highest credit quality.  The risk factors are negligible, being only
slightly more than for risk-free U.S. Treasury debt.

AA:  Long-term fixed income securities which are rated AA are judged to be of
high credit quality.  Protection factors are strong.  Risk is modest but may
vary slightly from time to time because of economic conditions.

Duff & Phelps applies modifiers AA+, AA, and AA- in the AA category for long-
term fixed income securities.  The modifier AA+ indicates that the security
ranks in the higher end of the AA category; the modifier AA indicates a mid-
range ranking; and the modifier AA-indicates that the issue ranks in the lower
end of the AA category.

FITCH INVESTORS SERVICE INC.

AAA:  Bonds which are rated AAA are considered to be investment grade and of the
highest credit quality.  The obligor has an exceptionally strong ability to pay
interest and repay principal, which is unlikely to be affected by reasonably
foreseeable events.

AA:  Bonds which are rated AA are considered to be investment grade and of very
high credit quality.  The obligor's ability to pay interest and repay principal
is very strong, although not quite as strong as bonds rated AAA.  Bonds rated in
the AAA and AA categories are not significantly vulnerable to foreseeable future
developments; short-term debt of these issuers is generally rated F-1+.

Fitch applies plus (+) and minus (-) modifiers in the AA category to indicate
the relative position of a credit within the rating category.  The modifier AA+
indicates that the security ranks at the higher end of the AA category than a
security rated AA or AA-.

IBCA LIMITED AND IBCA INC.
    
AAA:  Obligations which are rated AAA are considered to have the lowest
expectations of investment risk.  Capacity for timely repayment of principal and
interest is substantial, such that adverse changes in business, economic, or
financial conditions are unlikely to increase investment risk substantially.
     

                                      B-47
<PAGE>
 
AA:  Obligations which are rated AA are considered to have a very low
expectation of investment risk.  Capacity for timely repayment of principal and
interest is substantial.  Adverse changes in business, economic, or financial
conditions may increase investment risk albeit not very significantly.


THOMSON BANKWATCH, INC.

AAA: The highest category; indicates the ability to repay principal and interest
on a timely basis is extremely high.

AA: The second highest category; indicates a very strong ability to repay
principal and interest on a timely basis with limited incremental risk compared
to issues rated in the highest category.

Ratings in the Long-Term Debt categories may include a plus (+) or minus (-)
designation which indicates where within the respective category the issue is
placed.


B.   SHORT-TERM RATINGS

MOODY'S INVESTORS SERVICE, INC.

Moody's commercial paper ratings are opinions of the ability of issuers to repay
punctually promissory obligations not having an original maturity in excess of
nine months.

P-1:  Issuers or related supporting institutions are considered to have a
superior capacity for repayment of short-term promissory obligations.  Prime-1
or P-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.

P-2:  Issuers or related supporting institutions are considered to have a strong
capacity for repayment of short-term promissory obligations.  This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, will be more subject to
variation.

                                      B-48
<PAGE>
 
Capitalization characteristics, while still appropriate, may be more affected by
external conditions.  Ample alternate liquidity is maintained.


STANDARD & POOR'S RATINGS GROUP

Standard & Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt considered short-term in the relevant
market.

A-1:  The A-1 designation indicates the degree of safety regarding timely
payment is strong.  Those issues determined to possess extremely strong safety
characteristics will be denoted with a plus sign (+) designation.

A-2: Capacity for timely payment on issues with this designation is
satisfactory.  However, the relative degree of safety is not as high as for
issues designated A-1.

DUFF & PHELPS, INC.

Duff & Phelps' short-term debt ratings apply to all obligations with maturities
under one year.

Duff 1:  Commercial paper and certificates of deposit rated Duff 1 are
considered to have a very high certainty of timely payment.  Liquidity factors
are considered excellent and are supported by good fundamental protection
factors.  Risk factors are minor.

Duff 2:  Commercial paper and certificates of deposit rated Duff 2 are
considered to have a good certainty of timely payment.  Liquidity factors and
company fundamentals are considered sound.  Although ongoing internal funding
needs may enlarge total financing requirements, access to capital markets is
good and risk factors are small.

Duff & Phelps applies a plus and minus rating scale, Duff 1 plus, Duff 1 and
Duff 1 minus, in the Duff 1 top grade category for commercial paper and
certificates of deposits.  The rating Duff 1 plus indicates that the security
has the highest certainty of timely payment; short-term liquidity is outstanding
and safety is just below risk-free U.S. Treasury short-term obligations. The
rating Duff 1 minus indicates a high certainty of timely payment; liquidity
factors are strong and supported by good fundamental protection factors.  Risk
factors are very small.

FITCH INVESTORS SERVICE INC.

Fitch's short-term ratings apply to debt obligations that are payable on demand
or have original maturities of generally up to three years.

                                      B-49
<PAGE>
 
F-1:  Short-term debt obligations rated F-1 are considered to be of very strong
credit quality.  Those issues determined to possess exceptionally strong credit
quality and having the strongest degree of assurance for timely payment will be
denoted with a plus (+) sign designation.

F-2: Short-term debt obligations rated F-2 are considered to be of good credit
quality.  Issues assigned this rating have a satisfactory degree of assurance
for timely payment, but the margin of safety is not as great as for issues
assigned F-1+ and F-1 ratings.

IBCA LIMITED AND IBCA INC.

A1:  Short-term obligations rated A1 are supported by the capacity for timely
repayment.  A plus (+) sign is added to those issues determined to possess a
particularly strong credit feature.

A2:  Short-term obligations rated A2 are supported by a good capacity for timely
repayment.


THOMSON BANKWATCH, INC.

The TBW short-term ratings apply only to unsecured instrument that have a
maturity of one year or less.

The TBW short-term ratings specifically assess the likelihood of an untimely or
incomplete payment of principal and interest.

TBW-1:  The highest category; indicates a very high degree of likelihood that
principal and interest will be paid on a timely basis.

TBW-2:  The second highest category; while the degree of safety regarding timely
repayment of principal and interest is strong, the relative degree of safety is
not as high a for issues rated "TBW-1".

                                   APPENDIX A

     The Trust may from time to time use comparisons, graphs or charts in
advertisements to depict the following types of information:

          The performance of various types of securities (taxable money market
          funds, U.S. Treasury securities, adjustable rate mortgage securities,
          government securities) over time. However, the characteristics of
          these securities are not identical to, and may be very different from,
          those of a Fund's portfolio;

          Volatility of total return of various market indices (i.e. Lehman
          Government Bond Index, S&P 500, IBC/Donoghue's Money Fund Average/All
          Taxable Index) over varying periods of time.

          Credit Ratings of domestic government bonds in various countries.

          Price volatility comparisons of types of securities over different
          periods of time.

          Price and yield comparisons of a particular security over different
          periods of time.

          In addition, the Trust may from time to time include rankings of
     Goldman, Sachs & Co.'s research department by publications such as the
     Institutional Investor and the Wall Street Journal in advertisements.

                                  INTRODUCTION
    
Trust for Credit Unions (the "Fund") is an open-end, diversified, management
investment company (commonly known as a "mutual fund") offered only to state and
federally chartered credit unions and credit union service organizations.  The
Fund seeks to achieve a high level of income to the extent consistent with the
investment objectives of its investment portfolios:  the Money Market Portfolio,
the Government Securities Portfolio, the Mortgage Securities Portfolio, the
Target Maturity Portfolio (Feb 97) and the Target Maturity Portfolio (May 97).
This Additional Statement relates to the offering of the units of the Money
Market Portfolio, the Government Securities Portfolio and the Mortgage
Securities Portfolio (individually, a "Portfolio" and collectively, the
"Portfolios").     

The Fund was established under Massachusetts law by an Agreement and Declaration
of Trust dated September 24, 1987. The Agreement and Declaration of Trust
permits the Trustees to issue an unlimited number of full and fractional units
of beneficial interest of one or more separate series ("Portfolios")
representing interests in separate investment portfolios. The Trustees have the
right to establish investment portfolios in addition to those heretofore
established. Pursuant thereto, the Trustees have created the Money Market
Portfolio, the Government Securities Portfolio, the Mortgage Securities
Portfolio, the Target Maturity Portfolio (Feb 97) and the Target Maturity
Portfolio (May 97). Additional portfolios may be added in the future from time
to time. See "Additional Information" in the Prospectus. Investment in the
Portfolios relieves investors from the administrative and accounting burdens
involved in direct investments, and also provides related benefits as described
below.

High Current Income.  The Money Market Portfolio seeks to maximize current
- --------------------                                                      
income to the extent consistent with the preservation of capital and the
maintenance of liquidity by investing in high quality money market investments
authorized under the Federal Credit Union Act. The Government Securities and
Mortgage Securities Portfolios seek to achieve a higher current yield than a
money market fund, since they can invest in longer-term, higher yielding
securities, and may utilize certain investment techniques not available to a
money market fund. Similarly, the yields of the Government Securities and
Mortgage Securities Portfolios are expected to exceed that offered by bank
certificates of deposit and money market accounts. However, the Portfolios do
not maintain a constant net asset value per unit and are subject to greater
fluctuation in the value of their units than a money market fund. Unlike bank
certificates of deposit and money market accounts, investments in units of the
Portfolios are not insured or guaranteed by any government agency.

                                      B-3
<PAGE>
 
    
Relative Stability of Principal.  Unlike the Money Market Portfolio which seeks
- --------------------------------                                               
to maintain its net asset value per unit at $1.00 (although there is no
assurance that the Portfolio will be able to do so on a continuous basis), the
Government Securities and Mortgage Securities Portfolios' net asset values per
unit fluctuate.  The Government Securities Portfolio attempts to reduce net
asset value fluctuation by maintaining a maximum duration equal to that of a 2-
year U.S. Treasury security and a target duration no shorter than that of a 6-
month U.S. Treasury security and no longer than that of a one-year U.S. Treasury
security.  Similarly, the Mortgage Securities Portfolio attempts to reduce net
asset value fluctuation by maintaining a maximum duration that will not exceed
that of 3-year U.S. Treasury security and a target duration equal to that of a
2-year U.S. Treasury security and utilizing certain active management techniques
to hedge interest rate risk.  Duration, which is a measure of the price
sensitivity of the Portfolio, including expected cash flows and mortgage
prepayments under a wide range of interest rate scenarios, is reviewed and
recalculated daily. However, there is no assurance that these strategies will be
successful. There can be no assurance that Goldman, Sachs & Co.'s estimation of
a Portfolio's duration will be accurate or that the duration of a Portfolio will
always remain within the maximum target duration described above.     

Liquidity.  Because the Portfolios' units may be redeemed upon request of a
- ----------                                                                 
unitholder on any Business Day at net asset value, the Portfolios offer greater
liquidity than many competing investments such as certificates of deposit and
direct investments in certain mortgage-related securities.

Experienced Professional Management.  Successfully creating and managing a
- ------------------------------------                                      
diversified portfolio of mortgage-related securities requires professionals with
extensive experience.  Members of the Goldman, Sachs & Co.'s highly skilled
portfolio management team bring together many years of experience in the
analysis, valuation and trading of U.S. fixed income securities.  At September
30, 1996, they were responsible for approximately $22.4 billion in fixed income
assets including approximately $7 billion in mortgage-related securities.

A Sophisticated Investment Process.  The Portfolios' investment process starts
- -----------------------------------                                           
with a review of trends for the overall economy as well as for different sectors
of the U.S. mortgage and other markets.  Goldman, Sachs & Co.'s portfolio
managers then analyze yield spreads, implied volatility and the shape of the
yield curve.

In planning each Portfolio's strategy, the managers are able to draw upon the
economic and fixed income research resources of Goldman, Sachs & Co. They also
have access to the firm's proprietary models.  Among the quantitative techniques
used in the

                                      B-4
<PAGE>
 
Government Securities and Mortgage Securities Portfolios' investment process
are:

 .    option-adjusted analytics to make initial strategic asset allocations
     within the mortgage markets and to reevaluate investments as market
     conditions change; and

 .    analytics to estimate mortgage prepayments and cash flows under different
     interest rate scenarios and to maintain an optimal portfolio structure.

The Portfolio managers may use these and other trading and hedging techniques in
response to market and interest rate conditions.  In particular, these and other
evaluative tools help the portfolio managers select securities with investment
characteristics they believe are desirable.

Convenience of a Fund Structure.  The Government Securities and Mortgage
- --------------------------------                                        
Securities Portfolios eliminate many of the complications that direct ownership
of mortgage securities entails.  For example, most mortgage-related securities
generate monthly payments of both principal and interest, just as the underlying
mortgages do.  To conserve their principal, investors must make a special effort
to segregate and reinvest the principal portion of each payment on their own.
The Portfolios relieve investors of this chore by automatically reinvesting all
principal payments within the Portfolio and distributing only current income
each month.

                          ADVISORY AND OTHER SERVICES
INVESTMENT ADVISER

As stated in the Prospectus, Goldman, Sachs & Co., through Goldman Sachs Asset
Management ("GSAM"), One New York Plaza, 41st Floor, New York, New York 10004, a
separate operating division, acts as the Fund's investment adviser.  See
"Management--Investment Adviser and Transfer Agent" in the Prospectus for a
description of the investment advisory duties of Goldman, Sachs & Co. Goldman,
Sachs & Co.'s administrative obligations include, subject to the general
supervision of the Trustees of the Fund, (a) providing supervision of all
aspects of the Fund's non-investment operations not performed by others pursuant
to the Fund's administration agreement or custodian agreement, (b) providing the
Fund, to the extent not provided pursuant to such agreements or the Fund's
transfer agency agreement, with personnel to perform such executive,
administrative and clerical services as are reasonably necessary to provide
effective administration of the Fund, (c) arranging, to the extent not provided
pursuant to such agreements, for the preparation, at the Fund's expense, of its
tax returns, reports to unitholders, periodic updating of the Prospectus and
reports filed with the Securities and Exchange Commission (the "SEC") and other
regulatory authorities, (d) providing the Fund, to the extent not provided
pursuant to such agreements, with adequate office space and necessary office
equipment and services, (e) maintaining all of the Fund's records other than
those maintained pursuant to such agreements, (f) to the extent requested by the
Trustees of the Fund, negotiating changes to the terms and provisions of the
Fund's administration agreement, the custodian agreement and the distribution
agreement with Callahan Financial Services, Inc., and (g) reviewing and paying
(or causing to be paid) all bills or statements for services rendered to the
Fund.

The advisory agreement provides that Goldman, Sachs & Co. may render similar
services to others so long as its services under such agreement are not impaired
thereby.  The advisory agreement also provides that, subject to applicable
provisions of the 1940 Act, Goldman, Sachs & Co. will not be liable for any
error in judgment or mistake of law or for any loss suffered by the Fund except
a loss resulting from willful misfeasance, bad faith or gross negligence in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties, under the advisory agreement or the
transfer agency agreement.  The advisory agreement provides further that the
Fund will indemnify Goldman, Sachs & Co. against certain liabilities, including
liabilities under federal and state securities laws, or, in lieu thereof,
contribute to payment for resulting losses.

                                      B-9
<PAGE>
 
The advisory agreement will remain in effect with respect to a particular
Portfolio until March 31, 1997, and will continue from year to year thereafter

vote of a majority of the outstanding units of such Portfolio (as defined under
"Investment Restrictions") or by a majority of the Trustees of the Fund, and (b)
by the vote of a majority of the Trustees of the Fund who are not parties to the
advisory agreement or "interested persons" (as such term is defined in the 1940
Act) of any party thereto, cast in person at a meeting called for the purpose of
voting on such approval.  The  advisory agreement will terminate automatically
if assigned (as defined in the 1940 Act) and is terminable at any time with
respect to any Portfolio without penalty by the Trustees of the Fund or by vote
of a majority of the outstanding units of the Portfolio (as defined under
"Investment Restrictions") on 60 days' written notice to Goldman, Sachs & Co.
and by Goldman, Sachs & Co. on 60 days' written notice to the Fund.
         
Expenses borne by the Money Market Portfolio, Government Securities Portfolio
and Mortgage Securities Portfolio include, subject to the limitations described
in the Prospectus, the fees payable to Goldman, Sachs & Co. and CUFSLP, the fees
and expenses of the Fund's custodian, filing fees for the registration or
qualification of Portfolio units under federal and state securities laws,

asserted against the Fund for violation of any law, legal, auditing and tax

     Portfolio would have paid advisory fees of $893,178, $520,007 and $789,140,
     respectively, for such periods.  In addition, the expenses of the Money

     $78,198 and $198,584, respectively, by the Adviser for such periods.     

++   Waived additional advisory fees in the amount of $175,010 for such period.
     Without waivers, the Government Securities Portfolio would have paid an
     advisory fee of $1,822,189 for such period.
    
+++  Waived additional advisory fees in the amount of $59,027, $140,912 and
     $19,263, respectively, for such periods. Without waivers, the Mortgage
     Securities Portfolio would have paid advisory fees of $614,735, $529,099
     and $569,424, respectively, for such periods.     

                             PORTFOLIO TRANSACTIONS

In connection with portfolio transactions for the Fund, which are generally done
at a net price without a broker's commission (i.e., a dealer is dealing with the
Fund as principal and receives compensation equal to the spread between the
dealer's cost for a given security and the resale price of such security), the
Fund's advisory agreement provides that Goldman, Sachs & Co. shall attempt to
obtain the best net price and the most favorable execution.  On occasions when
Goldman, Sachs & Co. deems the purchase or sale of a security to be in the best
interests of a Portfolio as well as its other customers (including any other
Portfolio or other investment company or advisory account for

                                      B-11
<PAGE>
 
which Goldman, Sachs & Co. acts as investment adviser), the advisory agreement
provides that Goldman, Sachs & Co., to the extent permitted by applicable laws
and regulations, may aggregate the securities to be sold or purchased for the
Portfolio with those to be sold or purchased for such other customers in order
to obtain the best net price and most favorable execution.  In such event,
allocation of the securities so purchased or sold, as well as the expenses
incurred in the transaction, will be made by Goldman, Sachs & Co. in the manner
it considers to be most equitable and consistent with its fiduciary obligations
to such Portfolio and such other customers.  In some instances, this procedure
may adversely affect the size of the position obtainable for such Portfolio.  To
the extent that the execution and price offered by more than one dealer are
believed to be comparable, the advisory agreement permits Goldman, Sachs & Co.,
in its discretion, to purchase and sell portfolio securities to and from dealers
who provide the Fund with brokerage or research services.
    
     During the fiscal year ended August 31, 1996, the Funds acquired and sold
securities issued by Lehman Brothers, Salomon Brothers, Inc., Daiwa Securities
America, Inc., Chase Securities, Bear Stearns Companies, Inc., Morgan Stanley
Group, Inc., Swiss Bank Corp., Union Bank, Nomura Securities International and
Smith Barney Shearson, Inc. At August 31, 1996, the Money Market Portfolio held
the following amounts of securities of its regular brokers/dealers, as defined
in Rule 10b-1 under the 1940 Act, or their parents ($ in thousands):  Chase
Securities - $42,117; Daiwa Securities America, Inc. - $5,042; Bear Stearns
Companies, Inc. - $72,014; Smith Barney Shearson, Inc. - $2,150; Swiss Bank
Corp. - $8,475; and Nomura Securities International - $10,550. The Government

ACTIVITIES OF GOLDMAN, SACHS & CO. AND ITS AFFILIATES AND OTHER ACCOUNTS MANAGED
- --------------------------------------------------------------------------------
BY GOLDMAN SACHS.  The involvement of Goldman, Sachs & Co. and its advisory
- -----------------                                                          
affiliates in the management of, or interest in, other accounts and other
activities of Goldman, Sachs & Co. may present conflicts of interest with
respect to the Portfolio or impede their investment activities.
    
     Goldman, Sachs & Co. and its advisory affiliates have proprietary interests
in, and manage or advise, accounts or funds (including separate accounts and
other funds and collective investment vehicles) which have investment objectives
similar to those of the Portfolios and/or engage in transactions in the same
types of securities and instruments as the Portfolios. Goldman,     

                                      B-12
<PAGE>
 
    
Sachs & Co. and its affiliates are major participants in the fixed income
markets, in each case on a proprietary basis and for the accounts of customers.
As such, Goldman, Sachs & Co. and its affiliates are actively engaged in
transactions in the same securities and instruments in which the Portfolios
invest.  Such activities could affect the prices and availability of the
securities and instruments in which the Portfolios will invest, which could have
an adverse impact on each Portfolio's performance.  Such transactions,
particularly in respect of proprietary accounts or customer accounts other than
those included in Goldman, Sachs & Co. and its advisory affiliates' asset
management activities, will be executed independently of the Portfolios'
transactions and thus at prices or rates that may be more or less favorable.
When Goldman, Sachs & Co. or an advisory affiliate seeks to purchase or sell the
same assets for its managed accounts, including a Portfolio, the assets actually
purchased or sold may be allocated among the accounts on a basis determined in
its good faith discretion to be equitable.  In some cases, this system may
adversely affect the size or the price of the assets purchased or sold for the
Portfolios.

     From time to time, a Portfolio's activities may be restricted because of
regulatory restrictions applicable to Goldman, Sachs & Co. and its affiliates,
and/or their internal policies designed to comply with such restrictions.  As a
result, there may be periods, for example, when Goldman, Sachs & Co. will not
initiate or recommend certain types of transactions in certain securities or
instruments with respect to which Goldman, Sachs & Co. and/or its affiliates are
performing services or when position limits have been reached.

     In connection with its management of the Portfolios, GSAM may have access
to certain fundamental analysis and proprietary technical models developed by
Goldman, Sachs & Co. and other affiliates.  GSAM will not be under any
obligation, however, to effect transactions on behalf of the Portfolios in
accordance with such analysis and models.  In addition, neither Goldman, Sachs &
Co. nor any of its affiliates will have any obligation to make available any
information regarding their proprietary activities or strategies, or the
activities or strategies used for other accounts managed by them, for the
benefit of the management of the Portfolios and it is not anticipated that GSAM
will have access to such information for the purpose of managing the Portfolios.
The proprietary activities or portfolio strategies of Goldman, Sachs & Co. and
its affiliates or the activities or strategies used for accounts managed by them
or other customer accounts could conflict with the transactions and strategies
employed by GSAM in managing the Portfolios.

     The results of each Portfolio's investment activities may differ
significantly from the results achieved by Goldman, Sachs & Co. and its
affiliates for their proprietary accounts or     

                                      B-13
<PAGE>
 
accounts (including investment companies or collective investment vehicles)
managed or advised by them.  It is possible that Goldman, Sachs & Co. and its
affiliates and such other accounts will achieve investment results which are
substantially more or less favorable than the results achieved by the
Portfolios.  Moreover, it is possible that the Portfolios will sustain losses
during periods in which Goldman, Sachs & Co. and its affiliates achieve
significant profits on their trading for proprietary or other accounts.  The
opposite result is also possible.

     An investment policy committee which may include managing directors of
Goldman, Sachs & Co. and its affiliates may develop general policies regarding
Portfolio activities, but will not be involved in the day-to-day management of
the Portfolios.  In such instances, those individuals may, as a result, obtain
information regarding the Portfolios' proposed investment activities which is
not generally available to the public.  In addition, by virtue of their
affiliation with Goldman, Sachs & Co., any such member of an investment policy
committee will have direct or indirect interests in the activities of Goldman
Sachs and its affiliates in securities and investments similar to those in which
the Portfolios invest.
    
     In addition, certain principals and certain of the employees of GSAM are
also principals or employees of Goldman, Sachs & Co. or their affiliated
entities.  As a result, the performance by these principals and employees of
their obligations to such other entities may be a consideration of which
investors in the Portfolios should be aware.

     GSAM may enter into transactions and invest in instruments on behalf of a
Portfolio in which customers of Goldman, Sachs & Co. serve as the counterparty,
principal or issuer.  In such cases, such party's interests in the transaction
will be adverse to the interests of the Portfolios, and such party may have no
incentive to assure that the Portfolios obtain the best possible prices or terms
in connection with the transactions.  Goldman, Sachs & Co. and its affiliates
may also create, write or issue derivative instruments for customers of Goldman,
Sachs & Co. or its affiliates, the underlying securities or instruments of which
may be those in which the Portfolios invest or which may be based on the
performance of a Portfolio.  The Portfolios may, subject to applicable law,
purchase investments which are the subject of an underwriting or other
distribution by Goldman, Sachs & Co. or its affiliates and may also enter into
transactions with other clients of Goldman, Sachs & Co. or its affiliates where
such other clients have interests adverse to those of the Portfolios.  At times,
these activities may cause departments of the Firm to give advice to clients
that may cause these clients to take actions adverse to the interests of the
client.  To the extent affiliated transactions are permitted, the Portfolios
will deal with Goldman, Sachs & Co. and its affiliates on an arm's-length basis.

     Each Portfolio will be required to establish business relationships with
its counterparties based on the Portfolio's own credit standing.  Neither
Goldman, Sachs & Co. nor its affiliates will have any obligation to allow their
credit to be used in connection with a Portfolio's establishment of its business
relationships, nor is it expected that a Portfolio's counterparties will rely on
the credit of Goldman, Sachs & Co. or any of its affiliates in evaluating the
Fund's creditworthiness.
    
     It is possible that a Portfolio's holdings will include securities of
entities for which Goldman, Sachs & Co. performs investment banking services as
well as securities of entities in which Goldman, Sachs & Co. makes a market.
From time to time, Goldman, Sachs & Co.'s activities may limit the Portfolios'
flexibility in purchases and sales of securities.  When Goldman, Sachs & Co. is
engaged in an underwriting or other distribution of securities of an entity,
GSAM may be prohibited from purchasing or recommending the purchase of certain
securities of that entity for the Portfolios.     

TRANSFER AGENT

Under its transfer agency agreement, Goldman, Sachs & Co. serves as transfer
agent and dividend disbursing agent for the Fund.  Goldman, Sachs & Co. has
undertaken to the Fund to (a) process and provide confirmations for purchase and
redemption transactions, (b) answer customer inquiries regarding the current
yield of, and certain other matters (e.g., account status information)
pertaining to, the Fund, (c) establish and maintain separate accounts with
respect to each unitholder, (d) provide periodic statements showing account
balances and (e) provide for dividends or distributions to unitholders.

                                      B-15
<PAGE>
 
As compensation for the services rendered to the Fund as transfer agent,
Goldman, Sachs & Co. is entitled to a fee of $18 per year for each unitholder
account plus reimbursement for certain expenses.
    
For the last three fiscal years, the transfer agency fees accrued by each
Portfolio were as follows:

+    Waived additional administration fees in the amount of $251,230, $163,831
 and $143,193, respectively.     


The administration agreement will remain in effect until March 31, 1997, and
will continue from year to year thereafter provided such continuance is
specifically approved at least annually (a) by the vote of a majority of the
Trustees and (b) by the vote of a majority of the Trustees of the Fund who are
not parties to the administration agreement or "interested persons" (as such
term is defined in the 1940 Act) of any party thereto (the "Disinterested
Trustees"), cast in person at a meeting called for the purpose of voting on such
approval.  The administration agreement may be terminated with respect to a
Portfolio at any time, without the payment of any penalty, by a vote of a
majority of the Disinterested Trustees or by vote of the majority of the
outstanding units of the Portfolio (as defined under "Investment Restrictions")
on 60 days' written notice to CUFSLP and by CUFSLP on 60 days' written notice to
the Fund.  The administration agreement

                                      B-17
<PAGE>
 
provides that it may be amended by the mutual consent of the Fund and CUFSLP,
but the consent of the Fund must be approved by vote of a majority of the
Disinterested Trustees cast in person at a meeting called for the purpose of
voting on such amendment.  The administration agreement will terminate
automatically if assigned (as defined in the 1940 Act).

The administration agreement provides that CUFSLP will not be liable for any
error in judgment or mistake of law or for any loss suffered by the Fund except
a loss resulting from willful misfeasance, bad faith or gross negligence in the
performance of its obligations and duties, or by reason of its reckless
disregard of its obligations and duties, under the agreement.  The agreement
provides further that the Fund will indemnify CUFSLP against certain
liabilities, including liabilities under the federal and state securities laws
or, in lieu thereof, contribute to payment for resulting losses.

The thirty-nine credit unions listed below are the limited partners of CUFSLP,
which created Trust for Credit Unions in conjunction with Goldman, Sachs & Co.
As of September 30, 1996, these credit unions had total assets of $23.9 billion
from 22 different states.

CUSTODIAN

State Street Bank and Trust Company ("State Street"), P.O. Box 1713, Boston,
Massachusetts 02105, is the custodian of the Fund's portfolio securities and
cash.  State Street also maintains the Fund's accounting records.  The Northern
Trust Company ("Northern") has been retained by State Street to serve as its
agent in connection with certain wire receipts and transfers of funds.

AUDITORS
    
Arthur Andersen LLP, independent public accountants, One International Place,
Boston, Massachusetts 02110, have been selected as auditors of the Fund.  In
addition to audit services, Arthur Andersen LLP prepare the Fund's federal and
state tax returns, and provide consultation and assistance on accounting,
internal control and related matters.  The financial statements of the Money
Market Portfolio, the Government Securities Portfolio and the Mortgage
Securities Portfolio, which are incorporated by reference into this Additional
Statement (under "Financial Statements") from the Fund's annual report to
unitholders for the fiscal year ended August 31, 1996 (the "Annual Report"), and
the data set forth under "Financial Highlights" in the Prospectus have been
audited by Arthur Andersen LLP, as indicated in their report with respect
thereto, which is incorporated by reference in reliance upon the authority of
said firm as experts in giving said report.     


                            AMORTIZED COST VALUATION

As stated in the Prospectus, the Money Market Portfolio seeks to maintain a net
asset value of $1.00 per unit and, in this connection, values its instruments on
the basis of amortized cost pursuant to Rule 2a-7 under the 1940 Act.  The
amortized cost method values a security at its cost on the date of purchase and
thereafter assumes a constant amortization to maturity of any discount or
premium, regardless of the impact of fluctuating interest rates on the market
value of the instrument.  While this method provides certainty in valuation, it
may result in periods during which value, as determined by amortized cost, is
higher or lower than the price the Portfolio would receive if it sold the

                                      B-21
<PAGE>
 
instrument.  During such periods the yield to investors in the Portfolio may
differ somewhat from that obtained in a similar entity which uses available
indications as to market value to value its portfolio instruments.  For example,
if the use of amortized cost resulted in a lower (higher) aggregate Portfolio
value on a particular day, a prospective investor in the Portfolio would be able
to obtain a somewhat higher (lower) yield and ownership interest than would
result from investment in such similar entity and existing investors would
receive less (more) investment income and ownership interest.  In this
connection, the amortized cost method may result in dilution of unitholder
interests.  Similar effects arise out of the rounding of the Portfolio's net
asset value per unit to the nearest one cent.  However, the Fund expects that
the procedures and limitations referred to in the following paragraphs of this
section will tend to minimize the differences referred to above.

Under Rule 2a-7, the Fund's Trustees, in supervising the Fund's operations and
delegating special responsibilities involving portfolio management to Goldman,
Sachs & Co., are obligated, as a particular responsibility within the overall
duty of care owed to the unitholders, to establish procedures reasonably
designed, taking into account current market conditions and the Money Market
Portfolio's investment objective, to stabilize the net asset value of such
Portfolio, as computed for the purposes of purchases and redemptions, at $1.00
per unit.  The Trustees' procedures include periodically monitoring the
difference (the "Market Value Difference") between the amortized cost value per
unit and the net asset value per unit based upon available indications of market
value, considering whether steps should be taken in the event such Market Value
Difference exceeds  1/2 of 1%, and the taking of such steps as they consider
appropriate (e.g., selling portfolio instruments to shorten average portfolio
maturity or to realize capital gains or losses, reducing or suspending
unitholder income accruals, redeeming units in kind, canceling units without
monetary consideration, or utilizing a net asset value per unit based upon
available indications of market value which under such circumstances would vary
from $1.00) to eliminate or reduce to the extent reasonably practicable any
material dilution or other unfair results to investors or existing unitholders
which might arise from Market Value Differences.  Available indications of
market value used by the Fund consist of actual market quotations or appropriate
substitutes which reflect current market conditions and include (a) quotations
or estimates of market value for individual portfolio instruments and/or (b)
values for individual portfolio instruments derived from market quotations
relating to varying maturities of a class of money market instruments.

Rule 2a-7 requires that the Money Market Portfolio limit its investments to
those which Goldman, Sachs & Co., under guidelines established by the Fund's
Board of Trustees, determines to

                                      B-22
<PAGE>
 
present minimal credit risks and which are "Eligible Securities" as defined by
the SEC and described in the Prospectus.  The Rule also calls for the Money
Market Portfolio to maintain a dollar weighted average portfolio maturity (not
more than 90 days) appropriate to its objective of maintaining a stable net
asset value per unit and precludes the purchase of any instrument deemed under
such Rule to have a remaining maturity of more than 397 days.

Generally, the maturity of an instrument held by the Money Market Portfolio
shall be deemed to be the period remaining until the date noted on the face of
the instrument as the date on which the principal amount must be paid or, in the
case of an instrument called for redemption, the date on which the redemption
payment must be made.  However, instruments having variable or floating interest
rates or demand features may be deemed to have remaining maturities as follows:
(a) a government security with a variable rate of interest readjusted no less
frequently than every thirteen months may be deemed to have a maturity equal to
the period remaining until the next readjustment of the interest rate; (b) an
instrument with a variable rate of interest, the principal amount of which is
scheduled on the face of the instrument to be paid in thirteen months or less,
may be deemed to have maturity equal to the period remaining until the next
readjustment of the interest rate; (c) an instrument with a variable rate of
interest that is subject to a demand feature may be deemed to have a maturity
equal to the longer of the period remaining until the next readjustment of the
interest rate or the period remaining until the principal amount can be
recovered through demand; (d) an instrument with a floating rate of interest
that is subject to a demand feature may be deemed to have a maturity equal to
the period remaining until the principal amount can be recovered through demand;
and (e) a repurchase agreement may be deemed to have a maturity equal to the
period remaining until the date on which the repurchase of the underlying
securities is scheduled to occur or, where no date is specified but the
agreement is subject to demand, the notice period applicable to a demand for the
repurchase of the securities.


                              DESCRIPTION OF UNITS

As the Prospectus indicates, the Fund's Trust Agreement permits the Trustees to
issue an unlimited number of full and fractional units of beneficial interest of
one or more separate series representing interests in different investment
portfolios.  Under the terms of the Trust Agreement, each unit of each series
has a par value of $.001, represents an equal proportionate interest in a
particular investment portfolio with each other unit and is entitled to such
dividends out of the income belonging to such investment portfolio as are
declared by the Trustees.  Upon liquidation of an investment portfolio,
unitholders thereof are

                                      B-23
<PAGE>
 
entitled to share pro rata in the net assets belonging to that investment
portfolio available for distribution.  Units do not have preemptive or
conversion rights.  Units when issued as described in the Prospectus are fully
paid and nonassessable, except as expressly set forth below.

Any Trustee may be removed by the unitholders with or without cause at any time
by vote of those unitholders holding not less than two-thirds of the units then
outstanding, cast in person or by proxy at any meeting called for that purpose.
The Trustees shall promptly call a meeting of unitholders for the purpose of
voting upon the question of removal of any Trustee when requested in writing to
do so by the holders of record of not less than 10% of the outstanding units.

Whenever ten or more unitholders of record who have been such for at least six
months preceding the date of application, and who hold in the aggregate either
units having a net asset value of at least $25,000 or at least 1% of the
outstanding units, whichever is less, shall apply to the Trustees in writing,
stating that they wish to communicate with other unitholders with a view to
obtaining signatures to a request for a unitholder meeting and include with such
application a form of communication and request which they wish to transmit, the
Trustees shall within five business days after receipt of such application
either (1) afford to such applicants access to a list of the names and addresses
of all unitholders as recorded on the books of the Fund or investment portfolio
involved; or (2) inform such applicants as to the approximate number of
unitholders of record, and the approximate cost of mailing to them the proposed
form of communication and request and, upon receipt of the material and the
expenses of mailing, shall promptly mail such materials to all unitholders
unless a majority of the Trustees believe that in their opinion either such
material contains untrue statements of fact or omits to state facts necessary to
make the statements contained therein not misleading, or would be in violation
of applicable law.  The Trustees shall thereafter comply with any order entered
by the SEC and the requirements of the 1940 Act and the Securities Exchange Act
of 1934.

In addition to Trustee election or removal as described in the Prospectus and as
further described herein, the Trust Agreement provides for unitholder voting
only (a) with respect to any contract as to which unitholder approval is
required by the 1940 Act, (b) with respect to any termination or reorganization
of the Fund or any Portfolio to the extent and as provided in the Trust
Agreement, (c) with respect to any amendment of the Trust Agreement (other than
amendments establishing and designating new investment portfolios, abolishing
investment portfolios, changing the name of the Fund or the name of any
investment portfolio, supplying any omission, curing any ambiguity or curing,
correcting or supplementing any provision thereof which is internally

                                      B-24
<PAGE>
 
inconsistent with any other provision thereof or which is defective or
inconsistent with the 1940 Act or with the requirements of the Internal Revenue
Code and applicable regulations for the Fund's obtaining the most favorable
treatment thereunder available to regulated investment companies), which
amendments require approval by a majority of the units entitled to vote, (d) to
the same extent as the stockholders of a Massachusetts business corporation as
to whether or not a court action, proceeding or claim should or should not be
brought or maintained derivatively or as a class action on behalf of the Fund or
the unitholders, and (e) with respect to such additional matters relating to the
Fund as may be required by the 1940 Act, the Trust Agreement, the By-Laws of the
Fund, any registration of the Fund with the SEC or any state, or as the Trustees
may consider necessary or desirable.

Under Massachusetts law, there is a possibility that unitholders of a business
trust could, under certain circumstances, be held personally liable as partners
for the obligations of the Trust.  The Trust Agreement contains an express
disclaimer of unitholder liability for acts or obligations of the Fund and
requires that notice of such disclaimer be given in each agreement, obligation
or instrument entered into or executed by the Trustees or any officer.  The
Trust Agreement provides for indemnification out of Fund property of any
unitholder charged or held personally liable for the obligations or liabilities
of the Fund solely by reason of being or having been a unitholder of the Fund
and not because of such unitholder's acts or omissions or for some other reason.
The Trust Agreement also provides that the Fund shall, upon proper and timely
request, assume the defense of any charge made against any unitholder as such
for any obligation or liability of the Fund and satisfy any judgment thereon.
Thus, the risk of a unitholder incurring financial loss on account of unitholder
liability is limited to circumstances in which the Fund itself would be unable
to meet its obligations.

The Trust Agreement provides that on any matter submitted to a vote of the
unitholders, all units entitled to vote, irrespective of investment portfolio,
shall be voted in the aggregate and not by investment portfolio except that (a)
as to any matter with respect to which a separate vote of any investment
portfolio is required by the 1940 Act or would be required under the
Massachusetts Business Corporation Law if the Fund were a Massachusetts business
corporation, such requirements as to a separate vote by the investment portfolio
shall apply in lieu of the aggregate voting as described above, (b) in the event
that the separate vote requirements referred to in (a) above apply with respect
to one or more investment portfolios, then subject to (c) below, the units of
all other investment portfolios shall vote as a single investment portfolio, and
(c) as to any matter which does not affect the interest of a particular
investment portfolio, only

                                      B-25
<PAGE>
 
unitholders of the affected investment portfolio shall be entitled to vote
thereon.

Rule 18f-2 under the 1940 Act provides that any matter required by the
provisions of the 1940 Act or applicable state law, or otherwise, to be
submitted to the holders of the outstanding voting securities of an investment
company such as the Fund shall not be deemed to have been effectively acted upon
unless approved by the holders of a majority of the outstanding units of each
investment portfolio affected by such matter.  Rule 18f-2 further provides that
an investment portfolio shall be deemed to be affected by a matter unless the
interests of each investment portfolio in the matter are identical or the matter
does not affect any interest of the investment portfolio.  Under the Rule, the
approval of an investment advisory agreement or any change in a fundamental
investment policy would be effectively acted upon with respect to an investment
portfolio only if approved by a majority of the outstanding units of such
investment portfolio.  However, the Rule also provides that the ratification of
the appointment of independent accountants, the approval of principal
underwriting contracts and the election of Trustees may be effectively acted
upon by unitholders of the Fund voting together in the aggregate without regard
to a particular investment portfolio.
    
As of October 18, 1996, the outstanding units of the Money Market Portfolio, the
Government Securities Portfolio and the Mortgage Securities Portfolio were
372,834,270.680, 54,121,383.318 and 33,699,607.857, respectively.  To the Fund's
knowledge, as of such date, the only entities which may have owned 5% or more of

                  ADJUSTABLE AND FIXED RATE MORTGAGE LOANS AND
                          MORTGAGE-RELATED SECURITIES

THE NATURE OF ADJUSTABLE AND FIXED RATE MORTGAGE LOANS

The following is a general description of the adjustable and fixed rate mortgage
loans which may be expected to underlie the mortgage-related securities in which
the Government Securities Portfolio, the Mortgage Securities Portfolio and, to a
lesser extent, the Money Market Portfolio invest.  The actual mortgage loans
underlying any particular issue of mortgage-related securities may differ
materially from those described below.

Adjustable Rate Mortgage Loans ("ARMs").  ARMs included in a mortgage pool will
generally provide for a fixed initial mortgage interest rate for a specified
period of time.  Thereafter, the interest rates (the "Mortgage Interest Rates")
may be subject to periodic adjustment based on changes in the applicable index
rate (the "Index Rate").  The adjusted rate would be equal to the Index Rate
plus a gross margin, which is a fixed percentage spread over the Index Rate
established for each ARM at the time of its origination.

Adjustable interest rates can cause payment increases that some mortgagors may
find difficult to make.  However, certain ARMs provide that the Mortgage
Interest Rate may not be adjusted to a rate above an applicable lifetime maximum
rate or below an applicable lifetime minimum rate for such ARM.  Certain ARMs
may also be subject to limitations on the maximum amount by which the Mortgage
Interest Rate may adjust for any single adjustment period (the "Maximum
Adjustment").  Other ARMs ("Negatively Amortizing ARMs") may provide instead or
as well for limitations on changes in the monthly payment on such ARMs.
Limitations on monthly payments can result in monthly payments which are more or
less than the amount necessary to amortize a Negatively Amortizing ARM by its
maturity at the Mortgage Interest Rate in effect in any particular month.  In
the event that a monthly payment is insufficient to pay the interest accruing on
a Negatively Amortizing ARM, any such excess interest is added to the principal
balance of the loan, causing negative amortization, and will be repaid through
future monthly payments.  It may take borrowers under Negatively Amortizing ARMs
longer periods of time to accumulate equity and may increase the likelihood of
default by such borrowers.  In the event that a monthly payment exceeds the

                                      B-27
<PAGE>
 
sum of the interest accrued at the applicable Mortgage Interest Rate and the
principal payment which would have been necessary to amortize the outstanding
principal balance over the remaining term of the loan, the excess (or
"accelerated amortization") further reduces the principal balance of the ARM.
Negatively Amortizing ARMs do not provide for the extension of their original
maturity to accommodate changes in their Mortgage Interest Rate.  As a result,
unless there is a periodic recalculation of the payment amount (which there
generally is), the final payment may be substantially larger than the other
payments.  These limitations on periodic increases in interest rates and on
changes in monthly payments protect borrowers from unlimited interest rate and
payment increase, but may result in increased credit exposure and prepayment
risks for lenders.

There are a number of indices which provide the basis for rate adjustments on
ARMs.  Commonly utilized indices include the one-year, three-year and five-year
constant maturity Treasury rates, the three-month Treasury Bill rate, the 180-
day Treasury Bill rate, rates of longer-term Treasury securities, the 11th
District Federal Home Loan Bank Cost of Funds, the National Median Cost of
Funds, the one-month, three-month, six-month or one year London Interbank
Offered Rate ("LIBOR"), the prime rate of a specific bank, or commercial paper
rates.  Some indices, such as the one-year constant maturity Treasury rate,
closely mirror changes in market interest rate levels.  Others, such as the 11th
District Federal Home Loan Bank Cost of Funds Index, tend to lag behind changes
in market rate levels and tend to be somewhat less volatile.  The degree of
volatility in the market value of the Portfolios will be influenced by the
length of the interest rate reset periods and the degree of volatility in the
applicable indices.

Fixed Rate Mortgage Loans.  Generally, fixed rate mortgage loans eligible for
inclusion in a mortgage pool (the "Fixed Rate Mortgage Loans") will bear simple
interest at fixed annual rates and have original terms to maturity ranging from
5 to 40 years.  Fixed Rate Mortgage Loans generally provide for monthly payments
of principal and interest in substantially equal installments for the
contractual term of the mortgage note in sufficient amounts to amortize fully
principal by maturity, although certain Fixed Rate Mortgage Loans provide for a
large final "balloon" payment upon maturity.

Legal Considerations of Mortgage Loans.  Legal Considerations of Mortgage Loans.
The following is a discussion of certain legal and regulatory aspects of the
ARMs and Fixed Rate Mortgage Loans expected to underlie the mortgage-related
securities in which the Portfolios may invest.  These regulations may impair the
ability of a mortgage lender to enforce its rights under the mortgage documents.
These regulations may adversely affect the Portfolios' investments in both
privately-issued mortgage-related

                                      B-28
<PAGE>
 
securities (in the case of the Mortgage Securities Portfolio) and obligations
issued or guaranteed by the U.S. Government, its agencies or instrumentalities
by delaying the receipt of payments derived from principal or interest on
mortgage loans affected by such regulations.

     1.  Foreclosure.  A foreclosure of a defaulted mortgage loan may be delayed
     due to compliance with statutory notice or service of process provisions,
     difficulties in locating necessary parties or legal challenges to the
     mortgagee's right to foreclose.  Depending upon market conditions, the
     ultimate proceeds of the sale of foreclosed property may not equal the
     amounts owed on the mortgage loan.

     Further, courts in some cases have imposed general equitable principles
     upon foreclosure generally designed to relieve the borrower from the legal
     effect of default and have required lenders to undertake affirmative and
     expensive actions to determine the causes for the default and the
     likelihood of loan reinstatement.

     2.  Rights of Redemption.  In some states, after foreclosure of a mortgage
     loan, the borrower and foreclosed junior lienors are given a statutory
     period in which to redeem the property, which right may diminish the
     mortgagee's ability to sell the property.

     3.   Legislative Limitations. In addition to anti-deficiency and related
     legislation, numerous other federal and state statutory provisions,
     including the federal bankruptcy laws and state laws affording relief to
     debtors, may interfere with or affect the ability of a secured mortgage
     lender to enforce its security interest. For example, a bankruptcy court
     may grant the debtor a reasonable time to cure any default on a mortgage
     loan, including a payment default. The court in certain instances, may also
     reduce the monthly payments due under such mortgage loan, change the rate
     of interest, reduce the principal balance of the loan to the then-current
     appraised value of the related mortgage property and alter the mortgage
     loan repayment schedule and grant priority to certain liens over the lien
     of the mortgage loan. If a court relieves a borrower's obligation to repay
     amounts otherwise due on a mortgage loan, the mortgage loan servicer will
     not be required to advance such amounts, and any loss in respect thereof
     will be borne by the holders of securities backed by such loans. In
     addition, numerous federal and state consumer protection laws impose
     penalties

                                      B-29
<PAGE>
 
     for failure to comply with specific requirements in connection with
     origination and servicing of mortgage loans.

     4.  "Due-on-Sale" Provisions.  Fixed-rate mortgage loans may contain a so-
     called "due-on-sale" clause permitting acceleration of the maturity of the
     mortgage loan if the borrower transfers the property.  The Garn-St. Germain
     Depository Institutions Act of 1982 sets forth nine specific instances in
     which no mortgage lender covered by that Act may exercise a "due-on-sale"
     clause upon a transfer of property.  The inability to enforce a "due-on-
     sale" clause or the lack of such a clause in mortgage loan documents may
     result in a mortgage loan being assumed by a purchaser of the property that
     bears an interest rate below the current market rate.

     5.  Usury Laws.  Some states prohibit charging interest on mortgage loans
     in excess of statutory limits.  If such limits are exceeded, substantial
     penalties may be incurred and, in some cases, enforceability of the
     obligation to pay principal and interest may be affected.

MORTGAGE-RELATED SECURITIES

Mortgage-related securities represent direct or indirect participations in, or
are collateralized by and payable from, mortgage loans secured by real property.

The investment characteristics of adjustable and fixed rate mortgage-related
securities differ from those of traditional fixed income securities.  The major
differences include the payment of interest and principal of mortgage-related
securities on a more frequent (usually monthly) schedule, and the possibility
that principal may be prepaid at any time due to prepayments on the underlying
mortgage loans.  These differences can result in significantly greater price and
yield volatility than is the case with traditional fixed income securities.  In
general, if a Portfolio purchases mortgage-related securities at a premium, a
faster than expected prepayment rate will reduce both the market value and the
yield to maturity from those which were anticipated.  A prepayment rate that is
slower than expected will have the opposite effect of increasing yield to
maturity and market value.  Conversely, if a Portfolio purchases mortgage-
related securities at a discount, faster than expected prepayments will
increase, while slower than expected prepayments will reduce, yield to maturity
and market value.

Prepayments on a pool of mortgage loans are influenced by changes in current
interest rates and a variety of economic, geographic, social and other factors
(such as changes in mortgagors' housing needs, job transfers, unemployment,
mortgagors' equity in the mortgage properties and servicing decisions).  The
timing and level of prepayments cannot be predicted.  Generally, however,

                                      B-30
<PAGE>
 
prepayments on mortgage loans will increase during a period of falling mortgage
interest rates and decrease during a period of rising mortgage interest rates.
Accordingly, the amounts of prepayments available for reinvestment by a
Portfolio are likely to be greater during a period of declining mortgage
interest rates.  If general interest rates decline, such prepayments are likely
to be reinvested at lower interest rates than the Portfolio was earning on the
mortgage-related  securities that were prepaid.

The rate of interest on mortgage-related securities is normally lower than the
interest rates paid on the mortgages included in the underlying pool due to the
annual fees paid to the servicer of the mortgage pool for passing through
monthly payments to certificateholders and to any guarantor, such as GNMA, and
due to any yield retained by the issuer.  Actual yield to the holder may vary
from the coupon rate, even if adjustable, if the mortgage-related securities are
purchased or traded in the secondary market at a premium or discount.  In
addition, there is normally some delay between the time the issuer receives
mortgage payments from the servicer and the time the issuer makes the payments
on the mortgage-related securities and this delay reduced the effective yield to
the holder of such securities.

The issuers of certain mortgage-backed obligations may elect to have the pool of
mortgage loans (or indirect interests in mortgage loans) underlying the
securities treated as a real estate mortgage investment conduit ("REMIC"), which
are subject to special federal income tax rules.  A description of the types of
mortgage-related securities in which the Portfolios may invest is provided
below.  The descriptions are general and summary in nature, and do not detail
every possible variation of the types of securities that are permissible for the
Portfolios.

1. Private Mortgage Pass-Through Securities

General Characteristics.  The Mortgage Securities Portfolio may invest in
privately-issued mortgage pass-through securities ("Mortgage Pass-Throughs")
which represent participation interests in pools of private mortgage loans
conveyed to the issuing trust and generally serviced for the trust by the
originator.  For federal income tax purposes, such trusts are generally treated
as grantor trusts or REMICs and, in either case, are generally not subject to
any significant amount of federal income tax at the entity level.  Mortgage
Pass-Throughs (whether fixed or adjustable rate) provide for monthly payments
that are a "pass-through" of the monthly interest and principal payments
(including any prepayments) made by the individual borrowers on the pooled
mortgage loans, net of any fees or other amounts paid to any guarantor,
administrator and/or servicer of the underlying mortgage loans.

                                      B-31
<PAGE>
 
Each mortgage pool underlying Mortgage Pass-Throughs will consist of mortgage
loans evidenced by promissory notes secured by first mortgages or first deeds of
trust or other similar security instruments creating a first lien on the
mortgaged properties (the "Mortgaged Properties").  The Mortgaged Properties
will consist of residential properties upon which are located detached
individual dwelling units, individual condominiums, townhouses, duplexes,
triplexes, fourplexes, rowhouses, manufactured homes, individual units in
planned unit developments and other attached dwelling units, vacation homes,
second homes, residential investment properties, multi-family units or
properties with mixed residential and commercial uses.  A trust fund with
respect to which a REMIC election has been made may include regular interests in
other REMICs which in turn will ultimately evidence interests in mortgage loans.

The seller or servicer of the underlying mortgage obligations will generally
make representations and warranties to certificateholders as to certain
characteristics of the mortgage loans and as to the accuracy of certain
information furnished to the trustee in respect of each such mortgage loan.
Upon a breach of any representation or warranty that materially and adversely
affects the interests of the related certificateholders in a mortgage loan, the
seller or servicer generally will be obligated either to cure the breach in all
material respects, to repurchase the mortgage loan or, if the related agreement
so provides, to substitute in its place a mortgage loan pursuant to the
conditions set forth therein.  Such a repurchase or substitution obligation
generally constitutes the sole remedy available to the related
certificateholders or the trustee for the material breach of any such
representation or warranty by the seller or servicer.

Description of Certificates.  Mortgage Pass-Throughs may be issued in one or
more classes of senior certificates and one or more classes of subordinate
certificates.  Each such class may bear a different pass-through rate.
Generally, each certificate will evidence the specified interest of the holder
thereof in the payments of principal or interest or both in respect of the
mortgage pool comprising part of the trust fund for such certificates.

Any class of certificates may also be divided into subclasses entitled to
varying amounts of principal and interest.  If a REMIC election has been made,
certificates of such subclasses may be entitled to payments on the basis of a
stated principal balance and stated interest rate, and payments among different
subclasses may be made on a sequential, concurrent, pro rata or disproportionate
basis, or any combination thereof.  The stated interest rate on any such
subclass of certificates may be a fixed rate or one which varies in direct or
inverse relationship to an objective interest index.  Subclasses of certificates
as to which a REMIC election has been made may have the features and struc-

                                      B-32
<PAGE>
 
tures described below under the caption "Multiple Class Pass-Through Securities
and Collateralized Mortgage Obligations."

Generally, each registered holder of a certificate will be entitled to receive
its pro rata share of monthly distributions of all or a portion of principal of
the underlying mortgage loans or of interest on the principal balances thereof,
which accrues at the applicable mortgage pass-through rate, or both.  The
difference between the mortgage interest rate and the related mortgage pass-
through rate (less the amount, if any, of retained yield) with respect to each
mortgage loan will generally be paid to the servicer as a servicing fee.  Since
certain adjustable rate mortgage loans included in a mortgage pool may provide
for deferred interest (i.e., negative amortization), the amount of interest
actually paid by a mortgagor in any month may be less than the amount of
interest accrued on the outstanding principal balance of the related mortgage
loan during the relevant period at the applicable mortgage interest rate.  In
such event, the amount of interest that is treated as deferred interest will be
added to the principal balance of the related mortgage loan and will be
distributed pro rata to certificateholders as principal of such mortgage loan
when paid by the mortgagor in subsequent monthly payments or at maturity.

Ratings.  The ratings assigned by an NRSRO to Mortgage Pass-Throughs address the
likelihood of the receipt of all distributions on the underlying mortgage loans
by the related certificateholders under the agreements pursuant to which such
certificates are issued.  A rating agency's ratings take into consideration the
credit quality of the related mortgage pool, including any credit support
providers, structural and legal aspects associated with such certificates, and
the extent to which the payment stream on such mortgage pool is adequate to make
payments required by such certificates.  A rating agency's ratings on such
certificates do not, however, constitute a statement regarding frequency of
prepayments on the related mortgage loans.  In addition, the rating assigned by
a rating agency to a certificate does not address the remote possibility that,
in the event of the insolvency of the issuer of certificates where a
subordinated interest was retained, the issuance and sale of the senior
certificates may be recharacterized as a financing and, as a result of such
recharacterization, payments on such certificates may be affected.

Types of Credit Support.  Mortgage pools created by non-governmental issuers
generally offer a higher yield than government and government-related pools
because of the absence of direct or indirect government or agency payment
guarantees.  To lessen the effect of failures by obligors on underlying assets
to make payments, Mortgage Pass-Throughs may contain elements of credit support.
Such credit support falls into two classes:  liquidity protection and protection
against ultimate default by an obligor

                                      B-33
<PAGE>
 
on the underlying mortgages.  Liquidity protection refers to the provision of
advances, generally by the entity administering the pools of mortgages, the
provision of a reserve fund, or a combination thereof, to ensure, subject to
certain limitations, that scheduled payments on the underlying pool are made in
a timely fashion.  Protection against ultimate default ensures ultimate payment
of the obligations on at least a portion of the mortgages in the pool.  Such
protection may be provided through guarantees, insurance policies or letters of
credit obtained from third parties, through various means of structuring the
transaction or through a combination of such approaches.

In addition, one or more classes of certificates of Mortgage Pass-Throughs may
be subordinate certificates which provide that the rights of the subordinate
certificateholders to receive any or a specified portion of distributions with
respect to the underlying mortgage loans may be subordinated to the rights of
the senior certificateholders.  If so structured, the subordination feature may
be enhanced by distributing to the senior certificateholders on certain
distribution dates, as payment of principal, a specified percentage (which
generally declines over time) of all principal prepayments received during the
preceding prepayment period ("shifting interest credit enhancement").  This will
have the effect of accelerating the amortization of the senior certificates
while increasing the interest in the trust fund evidenced by the subordinate
certificates.  Increasing the interest of the subordinate certificates relative
to that of the senior certificate is intended to preserve the availability of
the subordination provided by the subordinate certificates.  In addition,
because the senior certificateholders in a shifting interest credit enhancement
structure are entitled to receive a percentage of principal prepayments which is
greater than their proportionate interest in the trust fund, the rate of
principal prepayments on the mortgage loans will have an even greater effect on
the rate of principal payments and the amount of interest payments on, and the
yield to maturity of, the senior certificates.

In addition to providing for a preferential right of the senior
certificateholders to receive current distributions from the mortgage pool, a
reserve fund may be established relating to such certificates (the "Reserve
Fund").  The Reserve Fund may be created with an initial cash deposit by the
originator or servicer and augmented by the retention of distributions otherwise
available to the subordinate certificateholders or by excess servicing fees
until the Reserve Fund reaches a specified amount.

The subordination feature, and any Reserve Fund, is intended to enhance the
likelihood of timely receipt by senior certificateholders of the full amount of
scheduled monthly payments of principal and interest due them and will protect
the senior certificateholders against certain losses; however, in

                                      B-34
<PAGE>
 
certain circumstances the Reserve Fund could be depleted and temporary
shortfalls could result.  In the event the Reserve Fund is depleted before the
subordinated amount is reduced to zero, senior certificateholders will
nevertheless have a preferential right to receive current distributions from the
mortgage pool to the extent of the then outstanding subordinated amount.  Unless
otherwise specified, until the subordinated amount is reduced to zero, on any
distribution date any amount otherwise distributable to the subordinate
certificates or, to the extent specified, in the Reserve Fund will generally be
used to offset the amount of any losses realized with respect to the mortgage
loans ("Realized Losses").  Realized Losses remaining after application of such
amounts will generally be applied to reduce the ownership interest of the
subordinate certificates in the mortgage pool.  If the subordinated amount has
been reduced to zero, Realized Losses generally will be allocated pro rata among
all certificateholders in proportion to their respective outstanding interests
in the mortgage pool.

As an alternative, or in addition to the credit enhancement afforded by
subordination, credit enhancement for Mortgage Pass-Throughs may be provided by
mortgage insurance, hazard insurance, by the deposit of cash, certificates of
deposit, letters of credit, a limited guaranty or by such other methods as are
acceptable to a rating agency.  In certain circumstances, such as where credit
enhancement is provided by guarantees or a letter of credit, the security is
subject to credit risk because of its exposure to an external credit enhancement
provider.

Voluntary Advances.  Generally, in the event of delinquencies in payments on the
mortgage loans underlying the Mortgage Pass-Throughs, the servicer agrees to
make advances of cash for the benefit of certificate-holders, but only to the
extent that it determines such voluntary advances will be recoverable from
future payments and collections on the mortgage loans or otherwise.

Optional Termination.  Generally, the servicer may, at its option with respect
to any certificates, repurchase all of the underlying mortgage loans remaining
outstanding at such time as the aggregate outstanding principal balance of such
mortgage loans is less than a specified percentage (generally 5-10%) of the
aggregate outstanding principal balance of the mortgage loans as of the cut-off
date specified with respect to such series.

2. Government Mortgage-Related Securities

As stated in the Prospectus, certain mortgage-related securities acquired by the
Portfolios will be issued or guaranteed by the U.S. Government or one of its
agencies, instrumentalities or sponsored enterprises including but not limited
to the Government National Mortgage Association ("GNMA"), the Federal National

                                      B-35
<PAGE>
 
Mortgage Association ("FNMA") and the Federal Home Loan Mortgage Corporation
("FHLMC") ("Government Mortgage-Related Securities").  GNMA securities are
backed by the full faith and credit of the U.S. Government, which means that the
U.S. Government guarantees that the interest and principal will be paid when
due.  FNMA securities and FHLMC securities are not backed by the full faith and
credit of the U.S. Government; however, because of their ability to borrow from
the U.S. Treasury, they are generally viewed by the market as high quality
securities with minimal credit risks.  There are several types of guaranteed
mortgage-related securities currently available, including guaranteed mortgage
pass-through certificates and multiple-class securities, which include
guaranteed REMIC pass-through certificates and stripped mortgage-backed
securities.  The Portfolios will be permitted to invest in other types of
Government Mortgage-Related Securities that may be available in the future to
the extent such investment is consistent with their respective investment
policies and objectives.

GNMA Certificates.  GNMA is a wholly-owned corporate instrumentality of the
United States.  GNMA is authorized to guarantee the timely payment of the
principal of and interest on certificates that are based on and backed by a pool
of mortgage loans insured by the Federal Housing Administration ("FHA Loans"),
or guaranteed by the Veterans Administration ("VA Loans"), or by pools of other
eligible mortgage loans.  In order to meet its obligations under any guaranty,
GNMA is authorized to borrow from the United States Treasury in an unlimited
amount.

FNMA Certificates.  FNMA is a stockholder-owned corporation chartered under an
act of the United States Congress.  Each FNMA Certificate is issued and
guaranteed by and represents an undivided interest in a pool of mortgage loans
(a "Pool") formed by FNMA.  Each Pool consists of residential mortgage loans
("Mortgage Loans") either previously owned by FNMA or purchased by it in
connection with the formation of the Pool.  The Mortgage Loans may be either
conventional Mortgage Loans (i.e., not insured or guaranteed by any U.S.
Government agency) or Mortgage Loans that are either insured by the Federal
Housing Administration ("FHA") or guaranteed by the Veterans Administration
("VA").  The lenders originating and servicing the Mortgage Loans are subject to
certain eligibility requirements established by FNMA.

FNMA has certain contractual responsibilities.  With respect to each Pool, FNMA
is obligated to distribute scheduled monthly installments of principal and
interest after FNMA's servicing and guaranty fee, whether or not received, to
certificate holders.  FNMA is also obligated to distribute to holders of
certificates an amount equal to the full principal balance of any foreclosed
Mortgage Loan, whether or not such principal balance is actually recovered.  The
obligations of FNMA under its guaranty of the FNMA Certificates are obligations
solely of FNMA.

                                      B-36
<PAGE>
 
FHLMC Certificates.  FHLMC is a corporate instrumentality of the United
States.  The principal activity of FHLMC currently is the purchase of first
lien, conventional, residential mortgage loans and participation interests in
such mortgage loans and their resale in the form of mortgage securities,
primarily FHLMC Certificates.  A FHLMC Certificate represents a pro rata
interest in a group of mortgage loans or participation in mortgage loans (a
"FHLMC Certificate group") purchased by FHLMC.

FHLMC guarantees to each registered holder of a FHLMC Certificate the timely
payment of interest at the rate provided for by such Certificate (whether or not
received on the underlying loans).  FHLMC also guarantees to each registered
certificate holder ultimate collection of all principal of the related mortgage
loans, without any offset or deduction, but does not, generally, guarantee the
timely payment of scheduled principal.  The obligations of FHLMC under its
guaranty of FHLMC Certificates are obligations solely of FHLMC.

The mortgage loans underlying the FHLMC Certificates will consist of adjustable
rate or fixed rate mortgage loans with original terms of maturity of between ten
and thirty years.  Substantially all of these mortgage loans are secured by
first liens on one- to four-family residential properties or multi-family
projects.  Each mortgage loan must meet the applicable standards set forth in
the law creating FHLMC.  A FHLMC Certificate group may include whole loans,
participation interests in whole loans and undivided interests in whole loans
and participation comprising another FHLMC Certificate group.

3.  Multiple Class Pass-Through Securities and Collateralized Mortgage
Obligations
    
As stated, the Government Securities Portfolio and the Mortgage Securities
Portfolio may also invest in multiple class mortgage-related securities,
including collateralized mortgage obligations and REMIC pass-through or
participation certificates (collectively, "CMOs").  These multiple class
securities may be issued by U.S. Government agencies, instrumentalities or
sponsored enterprises, including FNMA and FHLMC or, in the case of the Mortgage
Securities Portfolio, by trusts formed by private originators of, or investors
in, mortgage loans.  In general, CMOs represent direct ownership interests in, a
pool of residential mortgage loans or mortgage pass-through securities (the
"Mortgage Assets"), the payments on which are used to make payments on the CMOs.
Investors may purchase beneficial interests in CMOs, which are known as
"regular" interests or "residual" interests.  The Portfolios do not intend to
purchase residual interests.     

Each class of CMOs often referred to as a "tranche," is issued at a specific
adjustable or fixed interest rate and must be fully retired no later than its
final distribution date.  Principal

                                      B-37
<PAGE>
 
prepayments on the Mortgage Assets underlying the CMOs may cause some or all of
the classes of CMOs to be retired substantially earlier than their final
distribution dates.

The principal of and interest on the Mortgage Assets may be allocated among the
several classes of CMOs in various ways.  In certain structures (known as
"sequential pay" CMOs), payments of principal, including any principal
prepayments, on the Mortgage Assets generally are applied to the classes of CMOs
in the order of their respective final distribution dates.  Thus, no payment of
principal will be made on any class of sequential pay CMOs until all other
classes having an earlier final scheduled distribution date have been paid in
full.

Additional structures of CMOs include, among others, "parallel pay" CMOs.
Parallel pay CMOs are those which are structured to apply principal payments and
prepayments of the Mortgage Assets to two or more classes concurrently on a
proportionate or disproportionate basis.  These simultaneous payments are taken
into account in calculating the final distribution date of each class.

A wide variety of CMOs may be issued in the parallel pay or sequential pay
structures.  These securities include accrual certificates (also known as "Z-
Bonds"), which do not accrue interest at a specified rate until all other
certificates having an earlier final scheduled distribution date have been
retired and such Z-Bonds are converted thereafter to an interest-paying
security, and planned amortization class ("PAC") certificates, which are
parallel pay CMOs which generally require that specified amounts of principal be
applied on each payment date to one or more classes of a CMO (the "PAC
Certificates"), even though all other principal payments and prepayments of the
Mortgage Assets are then required to be applied to one or more other classes of
the Certificates.  The scheduled principal payments for the PAC Certificates
generally have the highest priority on each payment date after interest due has
been paid to all classes entitled to receive interest currently.  Shortfalls, if
any, are added to the amount payable on the next payment date.  The PAC
Certificate payment schedule is taken into account in calculating the final
distribution date of each class of PAC.  In order to create PAC tranches, one or
more tranches generally must be created that absorb most of the volatility in
the underlying Mortgage Assets.  These tranches tend to have market prices and
yields that are much more volatile than the PAC classes.

FNMA CMOs are issued and guaranteed as to timely distribution of principal and
interest by FNMA.  That is to say, FNMA will be obligated to distribute on a
timely basis to holders of FNMA CMO Certificates required installments of
principal and interest and to distribute the principal balance of each class of
CMO in full, whether or not sufficient funds are otherwise available.

                                      B-38
<PAGE>
 
For FHLMC CMOs, FHLMC guarantees the timely payment of interest, and also
guarantees the payment of principal as payments are required to be made on the
underlying mortgage participation certificates ("Pcs").  Pcs represent undivided
interests in specified level payment, residential mortgages or participation
therein purchased by FHLMC and placed in a Pc pool.  With respect to principal
payments on Pcs, FHLMC generally guarantees ultimate collection of all principal
of the related mortgage loans without offset or deduction.  FHLMC also
guarantees timely payment of principal on certain Pcs, referred to as "Gold
Pcs."
         


                           OTHER INVESTMENT PRACTICES

LENDING OF PORTFOLIO SECURITIES
    
     The Government Securities Portfolio and the Mortgage Securities Portfolio
may seek to increase their income by lending portfolio securities to
institutions, such as banks and broker-dealers. These loans will be continuously
collateralized by cash, cash equivalents or Government Securities in an amount
at least equal to the market value of the securities loaned. Each Portfolio will
have the right to call a loan and obtain the securities loaned at any time on
five days notice. For the duration of a loan, each Portfolio will continue to
receive the equivalent of the interest paid by the issuer on the securities
loaned and will also receive compensation from investment of the collateral.
Each Portfolio will not have the right to vote any securities having voting
rights during the existence of the loan, but each Portfolio will call the loan
in anticipation of an important vote to be taken among holders of the securities
or the giving or withholding of their consent on a material matter affecting the
investment. As with other extensions of credit, there are risks of delay in
recovering, or even loss of rights in, the collateral should the borrower of the
securities fail financially. However, the loans will be made only to firms
deemed by Goldman, Sachs & Co. to be of good standing, and when, in its
judgment, the consideration which can be earned currently from securities loans
of this type justifies the attendant risk. If Goldman, Sachs & Co. determines to
make securities loans, it is expected that during the current fiscal year, that
such loans will not exceed 5% of a Portfolio's total assets.     

INVERSE FLOATING RATE SECURITIES
    
     The Government Securities Portfolio and the Mortgage Securities Portfolio
may, to the extent permitted by the National Credit Union Administration
("NCUA"), invest in leveraged inverse floating rate debt instruments ("inverse
floaters"). The interest rate on an inverse floater resets in the opposite
direction from     

                                      B-39
<PAGE>
 
the market rate of interest to which the inverse floater is indexed. An inverse
floater may be considered to be leveraged to the extent that its interest rate
varies by a magnitude that exceeds the magnitude of the change in the index rate
of interest. The higher degree of leverage inherent in inverse floaters is
associated with greater volatility in their market values. Accordingly, the
duration of an inverse floater may exceed its stated final maturity. Certain
inverse floaters may be deemed to be illiquid securities for purposes of a
Portfolio's 15% limitation on investments in such securities.


                            INVESTMENT RESTRICTIONS
    
As the Prospectus states, the Fund may only invest in obligations authorized
under the Federal Credit Union Act.  This restriction may not be changed without
the approval of the holders of a majority of the outstanding units of each
affected Portfolio as described below.  In addition, the Fund has adopted the
following enumerated fundamental investment restrictions, none of which may be
changed with respect to a Portfolio without the approval of the holders of a
majority of the outstanding units of the Portfolio as described below.  The Fund
may not:

     (1)  Invest any one Portfolio in the instruments of issuers conducting
     their principal business activity in the same industry if immediately after
     such investment the value of such Portfolio's investments in such industry
     would exceed 25% of the value of its total assets; provided that there is
     no limitation with respect to or arising out of (a) in the case of the
     Mortgage Securities Portfolio, investments in obligations issued or
     guaranteed by the U.S. Government or its agencies or instrumentalities or
     repurchase agreements by such Portfolio of securities collateralized by
     such obligations; or (b) in the case of the Government Securities
     Portfolio, investments in obligations issued or guaranteed by the U.S.
     Government or its agencies or instumentalities, repurchase agreements by
     such Portfolio of securities collateralized by such obligations or by cash,
     certificates of deposit, bankers' acceptances and bank repurchase
     agreements; or (c) in the case of the Money Market Portfolio, investments
     in obligations issued or guaranteed by the U.S. Government or its agencies
     or instrumentalities, repurchase agreements by such Portfolio of securities
     collateralized by such obligations or by cash, certificates of deposit,
     bankers' acceptances, bank repurchase agreements and other obligations
     issued or guaranteed by banks (except commercial paper); and provided
     further that during normal market conditions the Mortgage Securities
     Portfolio intends to invest at least 25% of the value of its total assets
     in mortgage-related securities. Note: The current position of the staff of
     the SEC is that only the Money Market Portfolio     

                                      B-40
<PAGE>
 
    
     may reserve freedom of action to concentrate in bank obligations and that
     the exclusion with respect to bank instruments referred to above may only
     be applied to instruments of domestic banks. The Fund intends to consider
     only obligations of domestic banks (as construed to include foreign
     branches of domestic banks to the extent they satisfy the above-referenced
     conditions) to be within this exclusion until such time, if ever, that the
     SEC staff modifies its position.

     (2)  Invest any one Portfolio in the instruments of any one issuer, other
     than the U.S. Government, its agencies or instrumentalities, if immediately
     after such investment, more than 5% of the value of such Portfolio's total
     assets would be invested in the instruments of such issuer, except that (a)
     up to 25% of the value of the total assets of the Money Market Portfolio
     and Government Securities Portfolio may be invested in repurchase
     agreements, certificates of deposit, bankers' acceptances, time deposits
     and federal funds without regard to such 5% limitation; (b) up to 25% of
     the value of the total assets of the Mortgage Securities Portfolio may be
     invested without regard to such 5% limit and (c) such 5% limitation shall
     not apply to repurchase agreements collateralized by obligations of the
     U.S. Government, its agencies or instrumentalities.     

     (3)  Make loans, except through (a) the purchase of debt obligations in
     accordance with each Portfolio's investment objective and policies, (b)
     repurchase agreements with banks, brokers, dealers and other financial
     institutions in accordance with the investment objectives of each
     Portfolio, (c) the lending of federal funds to qualified financial
     institutions in accordance with the investment objectives of each Portfolio
     and (d) the lending of securities in accordance with the investment
     objective of the Government Securities Portfolio and the Mortgage
     Securities Portfolio.

     (4)  Borrow money, except as a temporary measure, and then only in amounts
     not exceeding one third of the value of the Portfolio's net assets.

     (5)  Mortgage, pledge or hypothecate any assets except to secure permitted
     borrowings.

     (6)  Purchase or sell real estate, but this restriction shall not prevent
     the Fund from investing directly or indirectly in portfolio instruments
     secured by real estate or interests therein or issued by companies which
     invest in real estate or interests therein.

     (7)  Purchase or sell commodities or commodity contracts.

                                      B-41
<PAGE>
 
     (8)  Purchase any voting securities except of investment companies (closed-
     end investment companies in the case of the Money Market Portfolio and
     Government Securities Portfolio) solely to the extent permitted by the 1940
     Act, or invest in companies for the purpose of exercising control or
     management.  Subject to certain exceptions, the 1940 Act contains a
     prohibition against the Fund's investing more than 5% of its total assets
     in the securities of another investment company, investing more than 10% of
     its assets in securities of such investment company and all other
     investment companies or purchasing more than 3% of the total outstanding
     voting stock of another investment company.

     (9)  Act as an underwriter of securities.

     (10)  Issue senior securities as defined in the 1940 Act except insofar as
     the Fund may be deemed to have issued a senior security by reason of (a)
     borrowing of money to the extent permitted herein or (b) purchasing
     securities on a when-issued or delayed delivery basis.

     (11)  Purchase any security for the Money Market Portfolio that is
     restricted as to disposition under federal securities laws (foreign
     securities traded only in foreign markets are not regarded as restricted).

     (12)  Purchase any security on margin (except for delayed delivery or when-
     issued transactions or such short-term credits as are necessary for the
     clearance of transactions).

     (13)  Make short sales of securities or maintain a short position.

     (14)  Write, purchase or sell puts, calls or combinations thereof.
         
Pursuant to SEC Rule 2a-7, the Money Market Portfolio currently may not invest
more than 5% of its total assets in the securities of any one issuer (except
U.S. Government securities or repurchase agreements collateralized by such
obligations).  The Portfolio may, however, invest more than 5% of its total
assets in the First Tier Securities of a single issuer for a period of up to
three business days after the purchase thereof, although the Portfolio may not
make more than one such investment at any time. The limitations in this
paragraph are not, however, fundamental, and may be changed in the future
without shareholder vote to the extent permitted by the SEC.

"Value" for the purposes of all investment restrictions shall mean the value
used in determining a Portfolio's net asset value.  "U.S. Government securities"
shall mean securities issued or

                                      B-42
<PAGE>
 
guaranteed by the U.S. Government or any of its agencies, authorities or
instrumentalities.

For purposes of the foregoing limitations, any limitation which involves a
maximum percentage shall not be considered violated unless an excess over the
percentage occurs immediately after, and is caused by, an acquisition or
encumbrance of securities or assets of, or borrowings by, a Portfolio of the
Fund.

Borrowings by the Fund (if any) are not for investment leverage purposes but are
solely for extraordinary or emergency purposes or to facilitate management of
the Portfolios by enabling the Fund to meet redemption requests when the
liquidation of portfolio instruments is deemed to be disadvantageous or not
possible.  If due to market fluctuations or other reasons the total assets of a
Portfolio fall below 300% of its borrowings, the Fund will promptly reduce the
borrowings of such Portfolio in accordance with the 1940 Act.  No purchases of
securities will be made if borrowings exceed 5% of the value of the applicable
Portfolio's assets.  Mortgage dollar rolls that are not accounted for as
financings shall not constitute borrowings.

The prohibition against short sales and short positions does not include
transactions sometimes referred to as "short sales against the box" where the
Fund contemporaneously owns or has the right to obtain at no added cost
securities identical to those sold short.
    
As used in the Prospectus and this Additional Statement with respect to a change
in investment objective or fundamental investment restrictions, the approval of
an investment advisory agreement or the approval of a distribution agreement,
the term "majority of the outstanding units" of either the Fund or a particular
Portfolio of the Fund means the vote of the lesser of (i) 67% or more of the
units of the Fund or such Portfolio present at a meeting, if the holders of more
than 50% of the outstanding units of the Fund or such Portfolio are present or
represented by proxy, or (ii) more than 50% of the outstanding units of the Fund
or such Portfolio.     


                     CALCULATION OF PERFORMANCE QUOTATIONS

From time to time, quotation of the Money Market Portfolio's "yield" and
"effective yield," and the yields and the total return of the Government
Securities Portfolio and the Mortgage Securities Portfolio, may be quoted in
advertisements or communications to unitholders.  These advertisements and
communications may be part of marketing activities conducted by either or both
of the Fund's distributors on behalf of the Portfolios.  These performance
figures are calculated in the following manner.

                                      B-43

MONEY MARKET PORTFOLIO

Yield--the net annualized yield based on a specified 7-calendar day period
- -----                                                                     
calculated at simple interest rates.  Yield is calculated by determining the net
change, exclusive of capital changes, in the value of a hypothetical preexisting
account having a balance of one unit at the beginning of the period and dividing
the difference by the value of the account at the beginning of the base period
to obtain the base period return.  The yield is annualized by multiplying the
base period return by 365/7.  The yield figure is stated to the nearest
hundredth of one percent.
    
Effective Yield--the net annualized yield for a specified 7-calendar day period
- ---------------                                                                
assuming a reinvestment of dividends (compounding).  Effective yield is
calculated by the same method as yield except the yield figure is compounded by
adding 1, raising the sum to a power equal to 365 divided by 7, and subtracting
one from the result, according to the following formula: Effective Yield =
[(Base Period Return + 1) to the power of 365 divided by 7]-1     

For the seven-day period ended August 31, 1996, the yield and the effective
yield for the Money Market Portfolio were:

GOVERNMENT SECURITIES PORTFOLIO AND MORTGAGE SECURITIES PORTFOLIO

Yield--The yield of the Government Securities Portfolio and the Mortgage
- -----                                                                   
Securities Portfolio is calculated by dividing the net investment income per
unit (as described below) earned by such Portfolio during a 30-day period by the
maximum offering price per unit on the last day of the period and annualizing
the result on a semi-annual basis by adding one to the quotient, raising the sum
to the power of six, subtracting one from the result and then doubling the
difference.  The Portfolio's net investment income per unit earned during the
period is based on the average daily number of units outstanding during the
period entitled to receive dividends and includes dividends and interest earned
during the period minus expenses accrued for the period, net of reimbursements.
This calculation can be expressed as follows:

                            a-b
                  Yield =2[(--- + 1) to the 6th power- 1]               
                            cd

                                      B-44
<PAGE>
 
 Where:

     a=   dividends and interest earned during the period.

     b=   expenses accrued for the period (net of fee waivers).

     c=   the average daily number of units outstanding during the period that
          were entitled to receive dividends.

     d=   maximum offering price per unit on the last day of the period.

Except as noted below, interest earned on debt obligations held by the
Government Securities Portfolio and the Mortgage Securities Portfolio is
calculated by computing the yield to maturity of each obligation held by the
Portfolio based on the market value of the obligation (including actual accrued
interest) at the close of business on the last business day of each month, or,
with respect to obligations purchased during the month, the purchase price (plus
actual accrued interest) and dividing the result by 360 and multiplying the
quotient by the market value of the obligation (including actual accrued
interest) in order to determine the interest income on the obligation for each
day of the subsequent month that the obligation is held by the Portfolio.  The
maturity of an obligation with a call provision is the next call date on which
the obligation reasonably may be expected to be called or, if none, the maturity
date.  With respect to debt obligations purchased at a discount or premium, the
formula generally calls for amortization of the discount or premium.  The
amortization schedule will be adjusted monthly to reflect changes in the market
values of such debt obligations.

With respect to mortgage-related obligations which are expected to be subject to
monthly payments of principal and interest ("pay downs"), (a) gain or loss
attributable to actual monthly pay downs are accounted for as an increase or
decrease to interest income during the period; and (b) the Portfolio may elect
either (i) to amortize the discount and premium on the remaining security, based
on the cost of the security, to the weighted average maturity date, if such
information is available, or to the remaining term of the security, if any, if
the weighted average maturity date is not available, or (ii) not to amortize
discount or premium on the remaining security.

Total Return--The Government Securities Portfolio and the Mortgage Securities
- ------------                                                                 
Portfolio compute average annual total return by determining the average annual
compounded rates of return during specified periods that equate the initial
amount invested to the ending redeemable value of such investment.  This is done
by dividing the ending redeemable value of a hypothetical $1,000 initial payment
by $1,000 and raising the quotient to a power equal to one divided by the number
of years (or fractional

                                      B-45
<PAGE>
 
portion thereof) covered by the computation and subtracting one from the result.
This calculation can be expressed as follows:

                                ERV to the 1 divided by nth power
                         T = [(-----)- 1]             
                                P
Where:

     T = average annual total return

     ERV =  ending redeemable value at the end of the period covered by the
            computation of a hypothetical $1,000 payment made at the beginning
            of the period.

     P =  hypothetical initial payment of $1,000.

     n =  period covered by the computation, expressed in terms of years.

The Government Securities Portfolio and the Mortgage Securities Portfolio
compute their cumulative total return by determining the cumulative rate of
return during a specified period that likewise equates the initial amount
invested to the ending redeemable value of such investment.  The formula for
calculating cumulative total return is as follows:

                                ERV
                         T = [(---- - 1)]            
                                P 

Under the methods prescribed by the SEC, standardized calculations of average
annual total return assume the reinvestment of all dividends and capital gains
distributions on the reinvestment dates during the period (although a Portfolio
may also publish non-standardized calculations without this assumption).
Calculations of aggregate total return also assume the reinvestment of all
dividends and capital gains distributions on the reinvestment date during the
period.  The ending redeemable value (variable "ERV" in each formula) is
determined by assuming complete redemption of the hypothetical investment and
the deduction of all nonrecurring charges at the end of the period covered by
the computations.  Year-to-year total return is calculated in a similar manner.

ALL PORTFOLIOS

Each of the Portfolios may also quote from time to time distribution rates in
reports to unitholders and in sales literature. The distribution rate for a
specified period is calculated by dividing the total distribution per share by
the maximum offering price on the last day of the period and then annualizing
such amount.

In addition, from time to time, advertisements or information may include a
discussion of asset allocation models developed by GSAM and/or its affiliates,
certain attributes or benefits to be derived from asset allocation strategies
and the Goldman Sachs mutual funds that may be offered as investment options for

Performance data is based on historical results and is not intended to indicate
future performance.  Yield total return and distribution rates will vary based
on changes in market conditions, the level of interest rates, and Portfolio
expenses.  The value of units of the Government Securities Portfolio and
Mortgage Securities Portfolio will fluctuate, and an investor's units may be
worth more or less than their original cost upon redemption.

                       DESCRIPTION OF SECURITIES RATINGS*


A. LONG-TERM RATINGS

MOODY'S INVESTORS SERVICE, INC.

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 with Aaa securities.

Moody's applies numerical modifiers l, 2, and 3 in the Aa category.  The
modifier 1 indicates that the company ranks in the higher end of the Aa
category; the modifier 2 indicates a mid-range ranking; and the modifier 3
indicates that the issue ranks in the lower end of the Aa category.


STANDARD & POOR'S RATINGS GROUP

AAA:  Bonds rated AAA are highest grade debt obligations.  This rating indicates
an extremely strong capacity to pay interest and repay principal.

AA:  Capacity to pay interest and repay principal is very strong, and differs
from AAA issues only in small degree.

Plus (+) or Minus (-):  The AA rating may be modified by the addition of a plus
or minus sign to show relative standing within the AA category.



__________________________

*  The ratings systems described herein are believed to be the most recent
ratings systems available from Moody's Investors Service, Inc. and Standard &
Poor's Ratings Group at the date of this Additional Statement for the securities
listed.  Ratings are generally given to securities at the time of issuance.
While the rating agencies may from time to time revise such ratings, they
undertake no obligation to do so, and the ratings indicated do not necessarily
represent ratings which will be given to these securities throughout the period
they are held by a Portfolio.

                                      B-51
<PAGE>
 
r:        A rating may be modified by the addition of an "r" rating to highlight
derivative, hybrid and certain other obligations that Standard & Poor's believes
may experience high volatility or high variability in expected returns due to
non-credit risks.  The absence of an "r" symbol should not be taken as an
indication that an obligation will exhibit no volatility or variability in total
return.

DUFF & PHELPS, INC.

AAA:  Long-term fixed income securities which are rated AAA are judged to be of
the highest credit quality.  The risk factors are negligible, being only
slightly more than for risk-free U.S. Treasury debt.

AA:  Long-term fixed income securities which are rated AA are judged to be of
high credit quality.  Protection factors are strong.  Risk is modest but may
vary slightly from time to time because of economic conditions.

Duff & Phelps applies modifiers AA+, AA, and AA- in the AA category for long-
term fixed income securities.  The modifier AA+ indicates that the security
ranks in the higher end of the AA category; the modifier AA indicates a mid-
range ranking; and the modifier AA-indicates that the issue ranks in the lower
end of the AA category.


FITCH INVESTORS SERVICE INC.

AAA:  Bonds which are rated AAA are considered to be investment grade and of the
highest credit quality.  The obligor has an exceptionally strong ability to pay
interest and repay principal, which is unlikely to be affected by reasonably
foreseeable events.

AA:  Bonds which are rated AA are considered to be investment grade and of very
high credit quality.  The obligor's ability to pay interest and repay principal
is very strong, although not quite as strong as bonds rated AAA.  Bonds rated in
the AAA and AA categories are not significantly vulnerable to foreseeable future
developments; short-term debt of these issuers is generally rated F-1+.

Fitch applies plus (+) and minus (-) modifiers in the AA category to indicate
the relative position of a credit within the rating category.  The modifier AA+
indicates that the security ranks at the higher end of the AA category than a
security rated AA or AA-.

interest is substantial, such that adverse changes in business, economic, or
financial conditions are unlikely to increase investment risk substantially.

AA:  Obligations which are rated AA are considered to have a very low
expectation of investment risk.  Capacity for timely repayment of principal and
interest is substantial.  Adverse changes in business, economic, or financial
conditions may increase investment risk albeit not very significantly.

B.        SHORT-TERM RATINGS

MOODY'S INVESTORS SERVICE, INC.

Moody's commercial paper ratings are opinions of the ability of issuers to repay
punctually promissory obligations not having an original maturity in excess of
nine months.

P-1:  Issuers or related supporting institutions are considered to have a
superior capacity for repayment of short-term promissory obligations.  Prime-1
or P-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.

P-2:  Issuers or related supporting institutions are considered to have a strong
capacity for repayment of short-term promissory obligations.  This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, will be more subject to
variation.  Capitalization characteristics, while still appropriate, may be more
affected by external conditions.  Ample alternate liquidity is maintained.

ly strong safety characteristics will be denoted with a plus sign (+)
designation.

satisfactory.  However, the relative degree of safety is not as high as for
issues designated A-1.


DUFF & PHELPS, INC.

Duff & Phelps' short-term debt ratings apply to all obligations with maturities
under one year.

Duff 1:  Commercial paper and certificates of deposit rated Duff 1 are
considered to have a very high certainty of timely payment.  Liquidity factors
are considered excellent and are supported by good fundamental protection
factors.  Risk factors are minor.

Duff 2:  Commercial paper and certificates of deposit rated Duff 2 are
considered to have a good certainty of timely payment.  Liquidity factors and
company fundamentals are considered sound.  Although ongoing internal funding
needs may enlarge total financing requirements, access to capital markets is
good and risk factors are small.

Duff & Phelps applies a plus and minus rating scale, Duff 1 plus, Duff 1 and
Duff 1 minus, in the Duff 1 top grade category for commercial paper and
certificates of deposits.  The rating Duff 1 plus indicates that the security
has the highest certainty of timely payment; short-term liquidity is outstanding
and safety is just below risk-free U.S. Treasury short-term obligations.  The
rating Duff 1 minus indicates a high certainty of timely payment; liquidity
factors are strong and supported by good fundamental protection factors. Risk
factors are very small.

Fitch's short-term ratings apply to debt obligations that are payable on demand
or have original maturities of generally up to three years.

credit quality.  Those issues determined to possess exceptionally strong credit
quality and having the strongest degree of assurance for timely payment will be
denoted with a plus (+) sign designation.

F-2: Short-term debt obligations rated F-2 are considered to be of good credit
quality.  Issues assigned this rating have a satisfactory degree of assurance
for timely payment, but the margin of safety is not as great as for issues
assigned F-1+ and F-1 ratings.

timely repayment.  A plus (+) sign is added to those issues determined to
