                           SUMMARY

Stein Roe Institutional High Yield Fund ("Institutional High 
Yield Fund") is a series of the Stein Roe Institutional Trust, 
an open-end diversified management investment company organized 
as a Massachusetts business trust.  Institutional High Yield 
Fund offers institutional investors the advantage of a "no-load" 
fund, with Stein Roe & Farnham Incorporated and its affiliates 
providing customized services as investment adviser, 
administrator, transfer agent, and distributor.  (See The Fund 
and Organization and Description of Shares.)  This prospectus is 
not a solicitation in any jurisdiction in which shares of 
Institutional High Yield Fund are not qualified for sale.

INVESTMENT OBJECTIVES AND POLICIES.  Institutional High Yield 
Fund invests all of its net investable assets in SR&F High Yield 
Portfolio ("High Yield Portfolio").  High Yield Portfolio 
invests in a diversified portfolio of securities in accordance 
with the identical investment objective and substantially the 
same investment policies as those of Institutional High Yield 
Fund.  High Yield Portfolio seeks total return by investing for 
a high level of current income and capital growth.  High Yield 
Portfolio invests primarily in high-yield, high-risk medium- and 
lower-quality debt securities.  Medium-quality debt securities, 
although considered investment grade, may have some speculative 
characteristics.  Lower-quality debt securities are obligations 
of issuers that are considered predominantly speculative with 
respect to the issuer's capacity to pay interest and repay 
principal according to the terms of the obligation and, 
therefore, carry greater investment risk, including the 
possibility of issuer default and bankruptcy, and are commonly 
referred to as "junk bonds." 

For a more detailed discussion of the investment objectives and 
policies, please see Investment Policies and Portfolio 
Investments and Strategies.  There is, of course, no assurance 
that Institutional High Yield Fund will achieve its investment 
objective.

INVESTMENT RISKS.  The risks inherent in Institutional High 
Yield Fund depend primarily upon the term and quality of the 
obligations in the investment portfolio of High Yield Portfolio, 
as well as on market conditions.  Interest rate fluctuations 
will affect the Fund's net asset value and, therefore, the total 
return from an investment in Institutional High Yield Fund.  
Interest rate fluctuations will affect income on variable rate 
securities and on securities purchased as other portfolio 
securities mature.  Since yields on debt securities available 
for purchase vary over time, no specific yield on shares of 
Institutional High Yield Fund can be assured.  Institutional 
High Yield Fund is designed for investors who can accept the 
heightened level of risk and principal fluctuation inherent in a 
portfolio that invests at least 65% of its assets in medium- and 
lower-quality debt securities.  High Yield Portfolio may invest 
in foreign securities, which may entail a greater degree of risk 
than investing in securities of domestic issuers.  Please see 
Investment Restrictions and Risks and Investment Considerations 
for further information.

PURCHASES AND REDEMPTIONS.  Fund shares are available primarily 
through pension plan administrators, broker-dealers, or other 
intermediaries (each an "Intermediary"), who provide accounting, 
recordkeeping, and other services to investors and who hold Fund 
shares in omnibus accounts for their clients.  For additional 
information on purchasing (buying) and redeeming (selling) 
shares, see How to Purchase Shares and How to Redeem Shares.

DISTRIBUTIONS.  Dividends are declared each business day and are 
paid monthly.  Dividends will be reinvested in additional shares 
of Institutional High Yield Fund unless the Intermediary holding 
the omnibus account elects to receive them in cash.  (See 
Distributions and Income Taxes.)

MANAGEMENT AND FEES.  Stein Roe & Farnham Incorporated (the 
"Adviser") is investment adviser to High Yield Portfolio.  In 
addition, it provides administrative services to Institutional 
High Yield Fund and High Yield Portfolio.  For a description of 
the Adviser and its fees, see Management.

EXAMPLE.
You would pay the following expenses on a $1,000 investment 
assuming (1) 5% annual return; and (2) redemption at the end of 
each time period:

                      1 year       3 years
                      ------       --------
                       $8            $24

The purpose of the Fee Table is to assist you in understanding 
the various costs and expenses that you will bear directly or 
indirectly as an investor in Institutional High Yield Fund.  
Because Institutional High Yield Fund has no operating history, 
the information in the table is based upon an estimate of 
expenses, assuming net assets of $50 million.  The figures 
assume that the percentage amounts listed under Annual Fund 
Operating Expenses remain the same during each of the periods 
and that all income dividends and capital gain distributions are 
reinvested in additional Fund shares.

   
From time to time, the Adviser may voluntarily waive a portion 
of its fees payable by Institutional High Yield Fund and the 
Fund's pro rata share of the fees payable by High Yield 
Portfolio.  The Adviser has agreed to voluntarily waive such 
fees to the extent the ordinary operating expenses of 
Institutional High Yield Fund exceed 0.75% of its annual average 
net assets.  This commitment expires on October 31, 1999, 
subject to earlier review and possible termination by the 
Adviser on 30 days' notice to the Fund.  Absent such expense 
undertaking, the estimated Management and Administrative Fees 
and Total Fund Operating Expenses would be 0.65% and 1.03%, 
respectively.  Any such reimbursement will lower Institutional 
High Yield Fund's overall expense ratio and increase its 
overall return to investors.  (Also see Management--Fees and 
Expenses.)
    

Institutional High Yield Fund pays the Adviser an administrative 
fee based on its average daily net assets and High Yield 
Portfolio pays the Adviser a management fee based on its average 
daily net assets.  The Fee Table summarizes the expenses of both 
Institutional High Yield Fund and High Yield Portfolio.  Fees 
and expenses are described under Management.  Institutional High 
Yield Fund bears its proportionate share of Portfolio expenses.  
The Trustees of Institutional Trust have considered whether the 
annual operating expenses of Institutional High Yield Fund, 
including its proportionate share of the expenses of High Yield 
Portfolio, would be more or less than if Institutional High 
Yield Fund invested directly in the securities held by High 
Yield Portfolio, and concluded that Institutional High Yield 
Fund's expenses would not be materially greater in such case.

The figures in the Example are not necessarily indicative of 
past or future expenses, and actual expenses may be greater or 
less than those shown.  Although information such as that shown 
in the Example and Fee Table is useful in reviewing 
Institutional High Yield Fund's expenses and in providing a 
basis for comparison with other mutual funds, it should not be 
used for comparison with other investments using different 
assumptions or time periods.

                          THE FUND

STEIN ROE INSTITUTIONAL HIGH YIELD FUND ("Institutional High 
Yield Fund") is a no-load, diversified "mutual fund."  
Institutional High Yield Fund does not impose commissions or 
charges when shares are purchased or redeemed.  Institutional 
High Yield Fund is a series of the Stein Roe Institutional Trust 
("Institutional Trust"), an open-end management investment 
company, which is authorized to issue shares of beneficial 
interest in separate series.  

Stein Roe & Farnham Incorporated (the "Adviser") provides 
portfolio management services to High Yield Portfolio and 
administrative services to Institutional High Yield Fund and 
High Yield Portfolio. 

Rather than invest in securities directly, Institutional High 
Yield Fund seeks to achieve its investment objective by using 
the "master fund/feeder fund" structure.  Under that structure, 
Institutional High Yield Fund and other investment companies 
and/or institutional investors with the same investment 
objective invest their assets in another investment company 
having the same investment objective and substantially the same 
investment policies and restrictions as Institutional High Yield 
Fund.  The purpose of such an arrangement is to achieve greater 
operational efficiencies and reduce costs.  Institutional High 
Yield Fund invests all of its net investable assets in shares of 
SR&F High Yield Portfolio ("High Yield Portfolio"), which is a 
series of SR&F Base Trust ("Base Trust").  (See Special 
Considerations Regarding Master Fund/Feeder Fund Structure.)  

                     INVESTMENT POLICIES

Institutional High Yield Fund and High Yield Portfolio each seek 
total return by investing for a high level of current income and 
capital growth.  Further information on portfolio investments 
and strategies may be found under Portfolio Investments and 
Strategies in this prospectus and in the Statement of Additional 
Information.  Institutional High Yield Fund seeks to achieve its 
objective by investing all of its assets in High Yield 
Portfolio.  The investment policies of High Yield Portfolio are 
substantially identical to those of Institutional High Yield 
Fund. 

High Yield Portfolio invests principally in high-yield, high-
risk medium- and lower-quality debt securities.  The medium- and 
lower-quality debt securities in which High Yield Portfolio will 
invest normally offer a current yield or yield to maturity that 
is significantly higher than the yield from securities rated in 
the three highest categories assigned by rating services such as  
Standard & Poor's Corporation ("S&P") and by Moody's Investors 
Service, Inc. ("Moody's").  

Under normal circumstances, at least 65% of High Yield 
Portfolio's assets will be invested in high-yield, high-risk 
medium- and lower-quality debt securities rated lower than Baa 
by Moody's or lower than BBB by S&P, or equivalent ratings as 
determined by other rating agencies, or unrated securities that 
the Adviser determines to be of comparable quality.  Medium-
quality debt securities, although considered investment grade, 
have some speculative characteristics.  Lower-quality debt 
securities are obligations of issuers that are considered 
predominantly speculative with respect to the issuer's capacity 
to pay interest and repay principal according to the terms of 
the obligation and, therefore, carry greater investment risk, 
including the possibility of issuer default and bankruptcy, and 
are commonly referred to as "junk bonds." Some issuers of debt 
securities choose not to have their securities rated by a rating 
service, and High Yield Portfolio may invest in unrated 
securities that the Adviser has researched thoroughly and 
believes are suitable for investment.  High Yield Portfolio may 
invest in debt obligations that are in default, but such 
obligations are not expected to exceed 10% of High Yield 
Portfolio's assets.  

High Yield Portfolio may invest up to 35% of its total assets in 
other securities including, but not limited to, pay-in-kind 
bonds, securities issued in private placements, bank loans, zero 
coupon bonds, foreign securities, convertible securities, 
futures, and options.  High Yield Portfolio may also invest in 
higher-quality debt securities.  Under normal market conditions, 
however, High Yield Portfolio is unlikely to emphasize higher-
quality debt securities since generally they offer lower yields 
than medium- and lower-quality debt securities with similar 
maturities.  High Yield Portfolio may also invest in common 
stocks and securities that are convertible into common stocks, 
such as warrants.

Investment in medium- or lower-quality debt securities involves 
greater investment risk, including the possibility of issuer 
default or bankruptcy.  High Yield Portfolio seeks to reduce 
investment risk through diversification, credit analysis, and 
evaluation of developments in both the economy and financial 
markets.  

An economic downturn could severely disrupt the high-yield 
market and adversely affect the value of outstanding bonds and 
the ability of the issuers to repay principal and interest.  In 
addition, lower-quality bonds are less sensitive to interest 
rate changes than higher-quality instruments (see Risks and 
Investment Considerations) and generally are more sensitive to 
adverse economic changes or individual corporate developments.  
During a period of adverse economic changes, including a period 
of rising interest rates, issuers of such bonds may experience 
difficulty in servicing their principal and interest payment 
obligations.

Achievement of the investment objective will be more dependent 
on the Adviser's credit analysis than would be the case if High 
Yield Portfolio were investing in higher-quality debt 
securities.  Since the ratings of rating services (which 
evaluate the safety of principal and interest payments, not 
market risks) are used only as preliminary indicators of 
investment quality, the Adviser employs its own credit research 
and analysis, from which it has developed a proprietary credit 
rating system based upon comparative credit analyses of issuers 
within the same industry.  These analyses may take into 
consideration such quantitative factors as an issuer's present 
and potential liquidity, profitability, internal capability to 
generate funds, debt/equity ratio and debt servicing 
capabilities, and such qualitative factors as an assessment of 
management, industry characteristics, accounting methodology, 
and foreign business exposure.

Lower-quality debt securities are obligations of issuers that 
are considered predominantly speculative with respect to the 
issuer's capacity to pay interest and repay principal according 
to the terms of the obligation and, therefore, carry greater 
investment risk, including the possibility of issuer default and 
bankruptcy, and are commonly referred to as "junk bonds."  The 
lowest rating assigned by Moody's is for bonds that can be 
regarded as having extremely poor prospects of ever attaining 
any real investment standing.  

Medium- and lower-quality debt securities tend to be less 
marketable than higher-quality debt securities because the 
market for them is less broad.  The market for unrated debt 
securities is even narrower.  During periods of thin trading in 
these markets, the spread between bid and asked prices is likely 
to increase significantly, and High Yield Portfolio may have 
greater difficulty selling its portfolio securities.  (See Net 
Asset Value.)  The market value of these securities and their 
liquidity may be affected by adverse publicity and investor 
perceptions.

           PORTFOLIO INVESTMENTS AND STRATEGIES


FOREIGN SECURITIES.  High Yield Portfolio may invest in foreign 
securities, but will not invest in a foreign security if, as a 
result of such investment, more than 25% of its total assets 
would be invested in foreign securities.  For purposes of this 
restriction, foreign debt securities do not include securities 
represented by American Depositary Receipts ("ADRs"), foreign 
debt securities denominated in U.S. dollars, or securities 
guaranteed by a U.S. person such as a corporation domiciled in 
the United States that is a parent or affiliate of the issuer of 
the securities being guaranteed.  High Yield Portfolio may 
invest in sponsored or unsponsored ADRs.  In addition to, or in 
lieu of, such direct investment, High Yield Portfolio may 
construct a synthetic foreign position by (a) purchasing a debt 
instrument denominated in one currency, generally U.S. dollars; 
and (b) concurrently entering into a forward contract to deliver 
a corresponding amount of that currency in exchange for a 
different currency on a future date and at a specified rate of 
exchange.  Because of the availability of a variety of highly 
liquid U.S. dollar debt instruments, a synthetic foreign 
position utilizing such U.S. dollar instruments may offer 
greater liquidity than direct investment in foreign currency 
debt instruments.  In connection with the purchase of foreign 
securities, High Yield Portfolio may contract to purchase an 
amount of foreign currency sufficient to pay the purchase price 
of the securities at the settlement date.  (See Risks and 
Investment Considerations.)

DERIVATIVES.  Consistent with its objective, High Yield 
Portfolio may invest in a broad array of financial instruments 
and securities, including conventional exchange-traded and non-
exchange traded options, futures contracts, futures options, 
securities collateralized by underlying pools of mortgages or 
other receivables, and other instruments, the value of which is 
"derived" from the performance of an underlying asset or a 
"benchmark" such as a security index, an interest rate, or a 
currency ("Derivatives").  High Yield Portfolio does not expect 
to invest more than 5% of its net assets in any type of 
Derivative except: options, futures contracts, and futures 
options.

Derivatives are most often used to manage investment risk or to 
create an investment position indirectly because they are more 
efficient or less costly than direct investment.  They also may 
be used in an effort to enhance portfolio returns.

The successful use of Derivatives depends on the Adviser's 
ability to correctly predict changes in the levels and 
directions of movements in security prices, interest rates and 
other market factors affecting the Derivative itself or the 
value of the underlying asset or benchmark.  In addition, 
correlations in the performance of an underlying asset to a 
Derivative may not be well established.  Finally, privately 
negotiated and over-the-counter Derivatives may not be as well 
regulated and may be less marketable than exchange-traded 
Derivatives.  For additional information on Derivatives, please 
refer to the Statement of Additional Information.

MORTGAGE AND OTHER ASSET-BACKED DEBT SECURITIES.  High Yield 
Portfolio may invest in securities secured by mortgages or other 
assets such as automobile or home improvement loans and credit 
card receivables.  These instruments may be issued or guaranteed 
by the U.S. Government or by its agencies or instrumentalities 
or by private entities such as commercial, mortgage and 
investment banks and financial companies or financial 
subsidiaries of industrial companies.

Securities issued by GNMA represent an interest in a pool of 
mortgages insured by the Federal Housing Administration or the 
Farmers Home Administration, or guaranteed by the Veterans 
Administration.  Securities issued by FNMA and FHLMC, U.S. 
Government-sponsored corporations, also represent an interest in 
a pool of mortgages.

The timely payment of principal and interest on GNMA securities 
is guaranteed by GNMA and backed by the full faith and credit of 
the U.S. Treasury.  FNMA guarantees full and timely payment of 
interest and principal on FNMA securities.  FHLMC guarantees 
timely payment of interest and ultimate collection of principal 
on FHLMC securities.  FNMA and FHLMC securities are not backed 
by the full faith and credit of the U.S. Treasury.

Mortgage-backed debt securities, such as those issued by GNMA, 
FNMA, and FHLMC, are of the "modified pass-through type," which 
means the interest and principal payments on mortgages in the 
pool are "passed through" to investors.  During periods of 
declining interest rates, there is increased likelihood that 
mortgages will be prepaid, with a resulting loss of the full-
term benefit of any premium paid by High Yield Portfolio on 
purchase of such securities; in addition, the proceeds of 
prepayment would likely be invested at lower interest rates.

Mortgage-backed securities provide either a pro rata interest in 
underlying mortgages or an interest in collateralized mortgage 
obligations ("CMOs"), which represent a right to interest and/or 
principal payments from an underlying mortgage pool.  CMOs are 
not guaranteed by either the U.S. Government or by its agencies 
or instrumentalities and are usually issued in multiple classes, 
each of which has different payment rights, pre-payment risks, 
and yield characteristics.  Mortgage-backed securities involve 
the risk of pre-payment of the underlying mortgages at a faster 
or slower rate than the established schedule.  Pre-payments 
generally increase with falling interest rates and decrease with 
rising rates, but they also are influenced by economic, social, 
and market factors.  If mortgages are pre-paid during periods of 
declining interest rates, there would be a resulting loss of the 
full-term benefit of any premium paid by High Yield Portfolio on 
purchase of the CMO, and the proceeds of pre-payment would 
likely be invested at lower interest rates.  High Yield 
Portfolio tends to invest in CMOs of classes known as planned 
amortization classes ("PACs") which have pre-payment protection 
features tending to make them less susceptible to price 
volatility.

Non-mortgage asset-backed securities usually have less pre-
payment risk than mortgage-backed securities, but have the risk 
that the collateral will not be available to support payments on 
the underlying loans which finance payments on the securities 
themselves.  Therefore, greater emphasis is placed on the credit 
quality of the security issuer and the guarantor, if any.

Asset-backed securities tend to experience greater price 
volatility than straight debt securities.

FLOATING RATE INSTRUMENTS.  High Yield Portfolio may also invest 
in floating rate instruments which provide for periodic 
adjustments in coupon interest rates that are automatically 
reset based on changes in amount and direction of specified 
market interest rates.  In addition, the adjusted duration of 
some of these instruments may be materially shorter than their 
stated maturities.  To the extent such instruments are subject 
to lifetime or periodic interest rate caps or floors, such 
instruments may experience greater price volatility than debt 
instruments without such features.  Adjusted duration is an 
inverse relationship between market price and interest rates and 
refers to the approximate percentage change in price for a 100 
basis point change in yield.  For example, if interest rates 
decrease by 100 basis points, a market price of a security with 
an adjusted duration of 2 would increase by approximately 2%.  
High Yield Portfolio does not intend to invest more than 5% of 
its net assets in floating rate instruments.

FUTURES AND OPTIONS.  High Yield Portfolio may purchase and 
write both call options and put options on securities, indexes 
and foreign currencies, and enter into interest rate, index and 
foreign currency futures contracts.  High Yield Portfolio may 
also write options on such futures contracts and purchase other 
types of forward or investment contracts linked to individual 
securities, indexes or other benchmarks, consistent with its 
investment objective,  in order to provide additional revenue, 
or to hedge against changes in security prices, interest rates, 
or currency fluctuations.  High Yield Portfolio may write a call 
or put option only if the option is covered.  As the writer of a 
covered call option, High Yield Portfolio foregoes, during the 
option's life, the opportunity to profit from increases in 
market value of the security covering the call option above the 
sum of the premium and the exercise price of the call.  There 
can be no assurance that a liquid market will exist when High 
Yield Portfolio seeks to close out a position.  Because of low 
margin deposits required, the use of futures contracts involves 
a high degree of leverage, and may result in losses in excess of 
the amount of the margin deposit.

LENDING OF PORTFOLIO SECURITIES.  Subject to certain 
restrictions, High Yield Portfolio may lend portfolio securities 
to broker-dealers and banks.  Any such loan must be continuously 
secured by collateral in cash or cash equivalents maintained on 
a current basis in an amount at least equal to the market value 
of the securities loaned by High Yield Portfolio.  High Yield 
Portfolio would continue to receive the equivalent of the 
interest or dividends paid by the issuer on the securities 
loaned, and would also receive an additional return that may be 
in the form of a fixed fee or a percentage of the collateral.  
High Yield Portfolio would have the right to call the loan and 
obtain the securities loaned at any time on notice of not more 
than five business days.  In the event of bankruptcy or other 
default of the borrower, High Yield Portfolio could experience 
both delays in liquidating the loan collateral or recovering the 
loaned securities and losses including (a) possible decline in 
the value of the collateral or in the value of the securities 
loaned during the period while the Portfolio seeks to enforce 
its rights thereto; (b) possible subnormal levels of income and 
lack of access to income during this period; and (c) expenses of 
enforcing its rights.

WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES; STANDBY 
COMMITMENTS.  High Yield Portfolio's assets may include 
securities purchased on a when-issued or delayed-delivery basis.  
Although the payment and interest terms of these securities are 
established at the time the purchaser enters into the 
commitment, the securities may be delivered and paid for a month 
or more after the date of purchase, when their value may have 
changed.  High Yield Portfolio makes such commitments only with 
the intention of actually acquiring the securities, but may sell 
the securities before settlement date if the Adviser deems it 
advisable for investment reasons.  Securities purchased in this 
manner involve a risk of loss if the value of the security 
purchased declines before the settlement date.

When-issued or delayed-delivery securities may sometimes be 
purchased on a "dollar roll" basis, meaning that High Yield 
Portfolio will sell securities with a commitment to purchase 
similar, but not identical, securities at a future date.  
Generally, the securities are repurchased at a price lower than 
the sales price.  Dollar roll transactions involve the risk of 
restrictions on the Portfolio's ability to repurchase the 
security if the counterparty becomes insolvent; an adverse 
change in the price of the security during the period of the 
roll or that the value of the security repurchased will be less 
than the security sold; and transaction costs exceeding the 
return earned by High Yield Portfolio on the sales proceeds of 
the dollar roll. 

High Yield Portfolio may also invest in securities purchased on 
a standby commitment basis, which is a delayed-delivery 
agreement in which High Yield Portfolio binds itself to accept 
delivery of a security at the option of the other party to the 
agreement.

PIK AND ZERO COUPON BONDS.  High Yield Portfolio may invest up 
to 20% of its total assets in zero coupon bonds and bonds the 
interest on which is payable in kind ("PIK bonds").  A zero 
coupon bond is a bond that does not pay interest for its entire 
life.  A PIK bond pays interest in the form of additional 
securities.  The market prices of both zero coupon and PIK bonds 
are affected to a greater extent by changes in prevailing levels 
of interest rates and thereby tend to be more volatile in price 
than securities that pay interest periodically and in cash.  In 
addition, because High Yield Portfolio accrues income with 
respect to these securities prior to the receipt of such 
interest in cash, it may have to dispose of portfolio securities 
under disadvantageous circumstances in order to obtain cash 
needed to pay income dividends in amounts necessary to avoid 
unfavorable tax consequences.  

SHORT SALES AGAINST THE BOX.  The Fund may sell short securities 
it owns or has the right to acquire without further 
consideration, a technique called selling short "against the 
box."  Short sales against the box may protect the Fund against 
the risk of losses in the value of its portfolio securities 
because any unrealized losses with respect to such securities 
should be wholly or partly offset by a corresponding gain in the 
short position.  However, any potential gains in such securities 
should be wholly or partially offset by a corresponding loss in 
the short position.  Short sales against the box may be used to 
lock in a profit on a security when, for tax reasons or 
otherwise, the Adviser does not want to sell the security.  For 
a more complete explanation, please refer to the Statement of 
Additional Information.

PORTFOLIO TURNOVER.  In attempting to attain its objective, High 
Yield Portfolio may sell portfolio securities without regard to 
the period of time they have been held.  Further, the Adviser 
may purchase and sell securities for the investment portfolio 
with a view to maximizing current return, even if portfolio 
changes would cause the realization of capital gains.  Although 
the average stated maturity of High Yield Portfolio will be from 
five to ten years, the Adviser may adjust the average effective 
maturity of High Yield Portfolio's portfolio from time to time, 
depending on its assessment of the relative yields available on 
securities of different maturities and its expectations of 
future changes in interest rates.  As a result, the turnover 
rate of High Yield Portfolio may vary from year to year.  The 
turnover rate for High Yield Portfolio may exceed 100%, but is 
not expected to exceed 200% under normal market conditions.  A 
high rate of portfolio turnover may result in increased 
transaction expenses and the realization of capital gains (which 
may be taxable) or losses.  (See Distributions and Income 
Taxes.)

                 INVESTMENT RESTRICTIONS

Neither Institutional High Yield Fund nor High Yield Portfolio 
may invest in a security if, as a result of such investment: (1) 
with respect to 75% of its assets, more than 5% of its total 
assets would be invested in the securities of any one issuer, 
except for U.S. Government Securities or repurchase agreements 
/1/; for such securities; or (2) 25% or more of its total assets 
would be invested in the securities of a group of issuers in the 
same industry, except that this restriction does not apply to 
U.S. Government Securities.  Notwithstanding these limitations, 
Institutional High Yield Fund, but not High Yield Portfolio, may 
invest all of its assets in another registered investment 
company having the same investment objective and substantially 
similar investment policies as the Fund.
- --------------
/1/ A repurchase agreement involves a sale of securities to High 
Yield Portfolio with the concurrent agreement of the seller 
(bank or securities dealer) to repurchase the securities at the 
same price plus an amount equal to an agreed-upon interest rate 
within a specified time.  In the event of a bankruptcy or other 
default of a seller of a repurchase agreement, the Portfolio 
could experience both delays in liquidating the underlying 
securities and losses.  The Portfolio may not invest more than 
10% of its net assets in repurchase agreements maturing in more 
than seven days and other illiquid securities.
- -------------

Neither Institutional High Yield Fund nor High Yield Portfolio 
may make loans except that it may (1) purchase money market 
instruments and enter into repurchase agreements; (2) acquire 
publicly-distributed or privately-placed debt securities; (3) 
lend its portfolio securities under certain conditions; and (4) 
participate in an interfund lending program with other Stein Roe 
Funds.  Neither may borrow money, except for non-leveraging, 
temporary, or emergency purposes or in connection with 
participation in the interfund lending program.  Neither the 
aggregate borrowings (including reverse repurchase agreements) 
nor the aggregate loans at any one time may exceed 33 1/3% of 
the value of total assets.  Additional securities may not be 
purchased when borrowings, less proceeds receivable from sales 
of portfolio securities, exceed 5% of total assets.

The policies set forth in the first two paragraphs under 
Investment Restrictions (but not the footnote) are fundamental 
policies of Institutional High Yield Fund and High Yield 
Portfolio. /2/  The Statement of Additional Information contains 
all of the investment restrictions.
- ---------------
/2/A fundamental policy may be changed only with the approval of 
a "majority of the outstanding voting securities" as defined in 
the Investment Company Act.

            RISKS AND INVESTMENT CONSIDERATIONS

The risks inherent in Institutional High Yield Fund depend 
primarily upon the term and quality of the obligations in High 
Yield Portfolio's investment portfolio, as well as on market 
conditions.  Although High Yield Portfolio seeks to reduce risk 
by investing in a diversified portfolio, this does not eliminate 
all risk.  Institutional High Yield Fund is designed for 
investors who can accept the heightened level of risk and 
principal fluctuation which might result from a portfolio that 
invests at least 65% of its assets in medium- and lower-quality 
debt securities.  

The market value of securities in the investment portfolio tends 
to vary inversely with the level of interest rates.  As a 
result, interest rate fluctuations may affect net asset value.  
(Because yields on debt securities available for purchase by 
High Yield Portfolio vary over time, no specific yield on shares 
of Institutional High Yield Fund can be assured.)  In addition, 
if the bonds in the investment portfolio contain call, 
prepayment or redemption provisions, during a period of 
declining interest rates, these securities are likely to be 
redeemed, and High Yield Portfolio may have to replace the 
security with a lower yielding security, resulting in a 
decreased return for investors.

Investments in foreign securities, including ADRs, represent 
both risks and opportunities not typically associated with 
investments in domestic issuers.  Risks of foreign investing 
include currency risk, less complete financial information on 
issuers, less market liquidity, more market volatility, less 
well-developed and regulated markets, and greater political 
instability.  In addition, various restrictions by foreign 
governments on investments by non-residents may apply, including 
imposition of exchange controls and withholding taxes on 
dividends, and seizure or nationalization of investments owned 
by non-residents.  Foreign investments also tend to involve 
higher transaction and custody costs.

High Yield Portfolio may enter into foreign currency forward 
contracts and use options and futures contracts, as described 
elsewhere in this prospectus, to limit or reduce foreign 
currency risk.

There can be no assurance that Institutional High Yield Fund or 
High Yield Portfolio will achieve its objective, nor can High 
Yield Portfolio assure that payments of interest and principal 
on portfolio securities will be made when due.  If, after 
purchase by High Yield Portfolio, the rating of a portfolio 
security is lost or reduced, High Yield Portfolio would not be 
required to sell the security, but the Adviser would consider 
such a change in deciding whether High Yield Portfolio should 
retain the security in its investment portfolio.

The investment objective of Institutional High Yield Fund and 
High Yield Portfolio is not fundamental and may be changed by 
the respective Board of Trustees without a vote of shareholders.

                  HOW TO PURCHASE SHARES

   
Fund shares are available primarily through pension plan 
administrators, broker-dealers, or other intermediaries (each an 
"Intermediary") who provide accounting, recordkeeping, and 
other services to investors and who hold Fund shares in omnibus 
accounts for their clients.  Shares may also be available to 
clients of the Adviser if, in the judgment of the Adviser, the 
sale of shares to such clients would not adversely affect the 
Fund or its shareholders.  The initial purchase minimum is 
$250,000 and the minimum subsequent investment is $10,000.  
Institutional Trust reserves the right to waive or lower its 
investment minimum for any reason.  Investors may be charged a 
fee if they effect transactions in Fund shares through a broker 
or agent.  The Adviser and Institutional High Yield Fund do not 
recommend, endorse, or receive compensation from any 
Intermediary.  
    

Each Intermediary will establish its own procedures applicable 
to its clients for the purchase of Institutional High Yield Fund 
shares in its account, including minimum initial and additional 
investments and the acceptable methods of payment for shares.  
Shares are purchased at the net asset value next determined 
after receipt of your order by the Fund's transfer agent.  Net 
asset value is calculated as of the close of the New York Stock 
Exchange ("NYSE"), generally 3:00 p.m., central time.  Your 
Intermediary may be closed on days when the NYSE is open.  
As a result, prices for Fund shares may be significantly 
affected on days when you have no access to your Intermediary 
to buy shares.  Institutional High Yield Fund will not issue 
a certificate for your shares.

   
Any purchase of shares must be paid for in U.S. dollars.  
Institutional High Yield Fund has the right to suspend the 
offering of its shares for a period of time.  Institutional High 
Yield Fund also has the right to accept or reject a purchase 
order in its sole discretion, including certain purchase orders 
using an exchange of shares.  
    

                     HOW TO REDEEM SHARES

If you purchased shares through an Intermediary, you can redeem 
(sell) all or some of your Fund shares only through an account 
with that Intermediary and in accordance with procedures 
established by the Intermediary applicable to its clients for 
the redemption of Fund shares.  Shares are redeemed at the net 
asset value next calculated after a redemption order is received 
and accepted by the Fund's transfer agent.  Your Intermediary may be 
closed on days when the NYSE is open.  As a result, prices for 
Institutional High Yield Fund shares may be significantly 
affected on days when you have no access to your Intermediary to 
redeem shares.

Redemption proceeds will be paid to Intermediaries as agreed 
with Institutional High Yield Fund, but in any case within seven 
calendar days.  Institutional High Yield Fund may suspend 
redemptions or postpone payments on days when the NYSE is closed 
(other than weekends and holidays), when trading on the NYSE is 
restricted, or as permitted by the Securities and Exchange 
Commission.

Institutional Trust reserves the right to redeem shares in any 
account and send the proceeds to the appropriate Intermediary if 
shares in that account do not have a value of at least $250,000.  
An Intermediary would be notified that its account is below the 
minimum and would be allowed 30 days to increase the account 
before the redemption is processed.

For information regarding exchanging shares of Institutional 
High Yield Fund for shares of another Stein Roe Fund, please see 
the Statement of Additional Information.

                      NET ASSET VALUE

   
The purchase and redemption price of Institutional High Yield 
Fund's shares is its net asset value per share.  Institutional 
High Yield Fund determines the net asset value of its shares as 
of the close of trading on the NYSE (currently 3:00 p.m., central 
time) by dividing the difference between the values of its assets 
and liabilities by the number of shares outstanding.  High Yield 
Portfolio allocates net asset value, income, and expenses to 
Institutional High Yield Fund and any other of its feeder funds 
in proportion to their respective interests in High Yield Portfolio.
    

Net asset value will not be determined on days when the NYSE is 
closed unless, in the judgment of the Board of Trustees, the net 
asset value of Institutional High Yield Fund should be 
determined on any such day, in which case the determination will 
be made at 3:00 p.m., central time.

Securities for which market quotations are readily available at 
the time of valuation are valued on that basis.  Long-term 
straight-debt securities for which market quotations are not 
readily available are valued at a fair value based on valuations 
provided by pricing services approved by the Board, which may 
employ electronic data processing techniques, including a matrix 
system, to determine valuations.  Short-term debt securities 
with remaining maturities of 60 days or less are valued at their 
amortized cost, which does not take into account unrealized 
gains or losses.  The Board believes that the amortized cost 
represents a fair value for such securities.  Short-term debt 
securities with remaining maturities of more than 60 days for 
which market quotations are not readily available are valued by 
use of a matrix prepared by the Adviser based on quotations for 
comparable securities.  Other assets and securities held by High 
Yield Portfolio for which these valuation methods do not produce 
a fair value are valued by a method that the Board believes will 
determine a fair value.

               DISTRIBUTIONS AND INCOME TAXES

DISTRIBUTIONS.  Income dividends are declared each business day, 
paid monthly, and confirmed at least quarterly.  Institutional 
High Yield Fund intends to distribute by the end of each 
calendar year at least 98% of any net capital gains realized 
from the sale of securities during the twelve-month period ended 
October 31 in that year.  Institutional High Yield Fund intends 
to distribute any undistributed net investment income and net 
realized capital gains in the following year.

All income dividends and capital gain distributions paid on 
shares in an account will be reinvested in additional shares 
unless the Intermediary or other account holder elects to have 
distributions paid in cash.  Reinvestment normally occurs on the 
payable date.  Institutional Trust reserves the right to 
reinvest the proceeds and future distributions in additional 
shares of Institutional High Yield Fund if checks for 
distributions mailed to the account holder are returned as 
undeliverable or are not presented for payment within six 
months.

INCOME TAXES.  Distributions to shareholders will be taxable, 
under income tax law, whether received in cash or reinvested in 
additional shares.  For federal income tax purposes, any 
distribution that is paid in January but was declared in the 
prior calendar year is deemed paid in the prior calendar year.

Shareholders will be subject to federal income tax at ordinary 
rates on income dividends and distributions of net short-term 
capital gain.  Distributions of net long-term capital gain will 
be taxable to you as long-term capital gain regardless of the 
length of time you have held your shares.

Shareholders will be advised annually as to the source of 
distributions.  If you are not subject to tax on your income, 
you will not be required to pay tax on these amounts.

If a shareholder realizes a loss on the sale or exchange of Fund 
shares held for six months or less, the short-term loss is 
recharacterized as long-term to the extent of any long-term 
capital gain distributions received with respect to those 
shares.

For federal income tax purposes, Institutional High Yield Fund 
is treated as a separate taxable entity distinct from any other 
series of the Institutional Trust.  High Yield Portfolio intends 
to qualify for the special tax treatment afforded regulated 
investment companies under Subchapter M of the Internal Revenue 
Code, so that it will be relieved of federal income tax on that 
part of its net investment income and net capital gain that is 
distributed to shareholders.

This section is not intended to be a full discussion of income 
tax laws and their effect on shareholders.  You may wish to 
consult your own tax advisor.

                    INVESTMENT RETURN

The total return from an investment in Institutional High Yield 
Fund is measured by the distributions received (assuming 
reinvestment) plus or minus the change in the net asset value 
per share for a given period.  A total return percentage may be 
calculated by dividing the value of a share at the end of the 
period (including reinvestment of distributions) by the value of 
the share at the beginning of the period and subtracting one.  
For a given period, an average annual total return may be 
calculated by finding the average annual compounded rate that 
would equate a hypothetical $1,000 investment to the ending 
redeemable value.

The yield of Institutional High Yield Fund is calculated by 
dividing its net investment income per share (a hypothetical 
figure as defined in the SEC rules) during a 30-day period by 
the net asset value per share on the last day of the period.  
The yield formula provides for semiannual compounding, which 
assumes that net investment income is earned and reinvested at a 
constant rate and annualized at the end of a six-month period.

Comparison of Institutional High Yield Fund's yield or total 
return with those of alternative investments should consider 
differences between Institutional High Yield Fund and the 
alternative investments, the periods and methods used in 
calculation of the return being compared, and the impact of 
taxes on alternative investments.  Yield figures are not based 
on actual dividends paid.  Past performance is not necessarily 
indicative of future results.  To obtain current yield or total 
return information, you may call 800-322-0593.

                         MANAGEMENT

   
TRUSTEES AND INVESTMENT ADVISER.  The Board of Trustees of the

Institutional Trust and Institutional High Yield Fund; the Board 
of Base Trust has overall management responsibility for 
High Yield Portfolio.  See Management in the Statement of 
Additional Information for the names of and other information 
about the trustees and officers.  Since Institutional Trust and 
Base Trust have the same trustees, the trustees have adopted 
conflict of interest procedures to monitor and address potential 
conflicts between the interests of Institutional High Yield Fund 
and High Yield Portfolio.

portion of its fees.

The Adviser provides office space and executive and other 
personnel to Institutional Trust and Base Trust and bears any 
sales or promotional expenses.  All expenses of Institutional 
High Yield Fund (other than those paid by the Adviser) 
including, but not limited to, printing and postage charges, 
securities registration fees, custodian and transfer agency 
fees, legal and auditing fees, compensation of trustees not 
affiliated with the Adviser, and expenses incidental to its 
organization are paid out of the assets of Institutional High 
Yield Fund.

Under a separate agreement with each Trust, the Adviser provides 
certain accounting and bookkeeping services to Institutional 
High Yield Fund and High Yield Portfolio including computation 
of net asset value and calculation of net income and capital 
gains and losses on disposition of assets.

PORTFOLIO TRANSACTIONS.  The Adviser places the orders for the 
purchase and sale of portfolio securities and options and 
futures contracts for Institutional High Yield Fund and High 
Yield Portfolio.  In doing so, the Adviser seeks to obtain the

            ORGANIZATION AND DESCRIPTION OF SHARES

Institutional Trust is a Massachusetts business trust organized 
under an Agreement and Declaration of Trust ("Declaration of 
Trust") dated July 31, 1996, which provides that each 
shareholder shall be deemed to have agreed to be bound by the 
terms thereof.  The Declaration of Trust may be amended by a 
vote of either Institutional Trust's shareholders or its 
trustees.  Institutional Trust may issue an unlimited number of 
shares, in one or more series as the Board may authorize.  
Currently, Institutional High Yield Fund is the only series 
authorized and outstanding.

Under Massachusetts law, shareholders of a Massachusetts 
business trust such as Institutional Trust could, in some 
circumstances, be held personally liable for unsatisfied 
obligations of Institutional Trust.  The Declaration of Trust 
provides that persons extending credit to, contracting with, or 
having any claim against, Institutional Trust or any particular 
series shall look only to the assets of Institutional Trust or 
of the respective series for payment under such credit, contract 
or claim, and that the shareholders, trustees and officers of 
Institutional Trust shall have no personal liability therefor.  
The Declaration of Trust requires that notice of such disclaimer 
of liability be given in each contract, instrument or 
undertaking executed or made on behalf of Institutional Trust.  
The Declaration of Trust provides for indemnification of any 
shareholder against any loss and expense arising from personal 
liability solely by reason of being or having been a 
shareholder.  Thus, the risk of a shareholder incurring 
financial loss on account of shareholder liability is believed 
to be remote, because it would be limited to circumstances in 
which the disclaimer was inoperative and Institutional Trust was 
unable to meet its obligations.

The risk of a particular series incurring financial loss on 
account of unsatisfied liability of another series of 
Institutional Trust is also believed to be remote, because it 
would be limited to claims to which the disclaimer did not apply 
and to circumstances in which the other Fund was unable to meet 
its obligations.

           SPECIAL CONSIDERATIONS REGARDING THE 
            MASTER FUND/FEEDER FUND STRUCTURE

Institutional High Yield Fund, an open-end management investment 
company, seeks to achieve its objective by investing all of its 
assets in shares of another mutual fund having an investment 
objective identical to that of Institutional High Yield Fund.  
The initial shareholder of Institutional High Yield Fund 
approved this policy of permitting Institutional High Yield Fund 
to act as a feeder fund by investing in High Yield Portfolio.  
Please refer to the Investment Policies, Portfolio Investments 
and Strategies, and Investment Restrictions for a description of 
the investment objectives, policies, and restrictions of 
Institutional High Yield Fund and High Yield Portfolio.  The 
management and expenses of both Institutional High Yield Fund 
and High Yield Portfolio are described under the Fee Table and 
Management.  Institutional High Yield Fund bears its 
proportionate share of Portfolio expenses.

The Adviser has provided investment management services in 
connection with other mutual funds employing the master 
fund/feeder fund structure since 1991.

SR&F High Yield Portfolio is a separate series of SR&F Base 
Trust ("Base Trust"), a Massachusetts common trust organized 
under an Agreement and Declaration of Trust ("Declaration of 
Trust") dated August 23, 1993.  The Declaration of Trust of the 
Base Trust provides that Institutional High Yield Fund and other 
investors in High Yield Portfolio will each be liable for all 
obligations of High Yield Portfolio that are not satisfied by 
High Yield Portfolio.  However, the risk of Institutional High 
Yield Fund incurring financial loss on account of such liability 
is limited to circumstances in which both inadequate insurance 
existed and High Yield Portfolio itself were unable to meet its 
obligations.  Accordingly, the Trustees of Institutional Trust 
believe that neither Institutional High Yield Fund nor its 
shareholders will be adversely affected by reason of 
Institutional High Yield Fund's investing in High Yield 
Portfolio.  

The Declaration of Trust of Base Trust provides that High Yield 
Portfolio will terminate 120 days after the withdrawal of 
Institutional High Yield Fund or any other investor in High 
Yield Portfolio, unless the remaining investors vote to agree to 
continue the business of High Yield Portfolio.  The Trustees of 
Institutional Trust may vote Institutional High Yield Fund's 
interests in High Yield Portfolio for such continuation without 
approval of Institutional High Yield Fund's shareholders.

The common investment objective of Institutional High Yield Fund 
and High Yield Portfolio is non-fundamental and may be changed 
without shareholder approval, subject, however, to at least 30 
days' advance written notice to Institutional High Yield Fund's 
shareholders.

The fundamental policies of Institutional High Yield Fund and 
the corresponding fundamental policies of the Portfolio can be 
changed only with shareholder approval.

If Institutional High Yield Fund, as a Portfolio investor, is 
requested to vote on a proposed change in fundamental policy of 
High Yield Portfolio or any other matter pertaining to High 
Yield Portfolio (other than continuation of the business of High 
Yield Portfolio after withdrawal of another investor), 
Institutional High Yield Fund will solicit proxies from its 
shareholders and vote its interest in High Yield Portfolio for 
and against such matters proportionately to the instructions to 
vote for and against such matters received from Fund 
shareholders.  Institutional High Yield Fund will vote shares 
for which it receives no voting instructions in the same 
proportion as the shares for which it receives voting 
instructions.  If there are other investors in High Yield 
Portfolio, there can be no assurance that any matter receiving a 
majority of votes cast by Fund shareholders will receive a 
majority of votes cast by all High Yield Portfolio investors.  
If other investors hold a majority interest in High Yield 
Portfolio, they could have voting control over High Yield 
Portfolio.  

In the event that High Yield Portfolio's fundamental policies 
were changed so as to be inconsistent with those of 
Institutional High Yield Fund, the Board of Trustees of 
Institutional Trust would consider what action might be taken, 
including changes to Institutional High Yield Fund's fundamental 
policies, withdrawal of Institutional High Yield Fund's assets 
from High Yield Portfolio and investment of such assets in 
another pooled investment entity, or the retention of another 
investment adviser.  Any of these actions would require the 
approval of Institutional High Yield Fund's shareholders.  
Institutional High Yield Fund's inability to find a substitute 
master fund or comparable investment management could have a 
significant impact upon its shareholders' investments.  Any 
withdrawal of Institutional High Yield Fund's assets could 
result in a distribution in kind of portfolio securities (as 
opposed to a cash distribution) to Institutional High Yield 
Fund.  Should such a distribution occur, Institutional High 
Yield Fund would incur brokerage fees or other transaction costs 
in converting such securities to cash.  In addition, a 
distribution in kind could result in a less diversified 
portfolio of investments for Institutional High Yield Fund and 
could affect the liquidity of Institutional High Yield Fund.

Each investor in High Yield Portfolio, including Institutional 
High Yield Fund, may add to or reduce its investment in High 
Yield Portfolio on each day the NYSE is open for business.  The 
investor's percentage of the aggregate interests in High Yield 
Portfolio will be computed as the percentage equal to the 
fraction (i) the numerator of which is the beginning of the day 
value of such investor's investment in High Yield Portfolio on 
such day plus or minus, as the case may be, the amount of any 
additions to or withdrawals from the investor's investment in 
High Yield Portfolio effected on such day; and (ii) the 
denominator of which is the aggregate beginning of the day net 
asset value of High Yield Portfolio on such day plus or minus, 
as the case may be, the amount of the net additions to or 
withdrawals from the aggregate investments in High Yield 
Portfolio by all investors in High Yield Portfolio.  The 
percentage so determined will then be applied to determine the 
value of the investor's interest in High Yield Portfolio as of 
the close of business.

Base Trust may permit other investment companies and/or other 
institutional investors to invest in High Yield Portfolio, but 
members of the general public may not invest directly in High 
Yield Portfolio.  Other investors in High Yield Portfolio are 
not required to sell their shares at the same public offering 
price as Institutional High Yield Fund, could incur different 
administrative fees and expenses than Institutional High Yield 
Fund, and their shares might be sold with a sales commission.  
Therefore, Fund shareholders might have different investment 
returns than shareholders in another investment company that 
invests exclusively in High Yield Portfolio.  Investment by such 
other investors in High Yield Portfolio would provide funds for 
the purchase of additional portfolio securities and would tend 
to reduce the Portfolio's operating expenses as a percentage of 
its net assets.  Conversely, large-scale redemptions by any such 
other investors in High Yield Portfolio could result in untimely 
liquidations of High Yield Portfolio's security holdings, loss 
of investment flexibility, and increases in the operating 
expenses of High Yield Portfolio as a percentage of its net 
assets.  As a result, High Yield Portfolio's security holdings 
may become less diverse, resulting in increased risk.

Currently one other investment company invests in High Yield 
Portfolio, and that is Stein Roe High Yield Fund, a series of 
Stein Roe Income Trust.  Information regarding any investment

                    APPENDIX--RATINGS

RATINGS IN GENERAL

A rating of a rating service represents the service's opinion as 
to the credit quality of the security being rated.  However, the 
ratings are general and are not absolute standards of quality or 
guarantees as to the creditworthiness of an issuer.  
Consequently, the Adviser believes that the quality of debt 
securities in which High Yield Portfolio invests should be 
continuously reviewed and that individual analysts give 
different weightings to the various factors involved in credit 
analysis.  A rating is not a recommendation to purchase, sell or 
hold a security because it does not take into account market 
value or suitability for a particular investor.  When a security 
has received a rating from more than one service, each rating 
should be evaluated independently.  Ratings are based on current 
information furnished by the issuer or obtained by the rating 
services from other sources that they consider reliable.  
Ratings may be changed, suspended or withdrawn as a result of 
changes in or unavailability of such information, or for other 
reasons.

The following is a description of the characteristics of ratings 
used by Moody's Investors Service, Inc. ("Moody's") and Standard 
& Poor's Corporation ("S&P").

CORPORATE BOND RATINGS

   
RATINGS BY MOODY'S
Aaa.   Bonds rated Aaa are judged to be 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 an exceptionally stable margin and principal is 
secure.  Although the various protective elements are likely to 
change, such changes as can be visualized are more unlikely to 
impair the fundamentally strong position of such bonds.
    

Aa.  Bonds 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 bonds or fluctuation of protective elements may be of 
greater amplitude or there may be other elements present which 
make the long-term risks appear somewhat larger than in Aaa 
bonds.

A.  Bonds rated A possess many favorable investment attributes 
and are to be considered as upper medium grade obligations.  
Factors giving security to principal and interest are considered 
adequate, but elements may be present which suggest a 
susceptibility to impairment sometime in the future.

Baa.  Bonds rated Baa are considered as medium grade 
obligations; i.e., they are neither highly protected nor poorly 
secured.  Interest payments and principal security appear 
adequate for the present but certain protective elements may be 
lacking or may be characteristically unreliable over any great 
length of time.  Such bonds lack outstanding investment 
characteristics and in fact have speculative characteristics as 
well.

Ba.  Bonds which are rated Ba are judged to have speculative 
elements; their future cannot be considered as well assured.  
Often the protection of interest and principal payments may be 
very moderate and thereby not well safeguarded during both good 
and bad times over the future.  Uncertainty of position 
characterizes bonds in this class.

B.  Bonds which are rated B generally lack characteristics of 
the desirable investment.  Assurance of interest and principal 
payments or of maintenance of other terms of the contract over 
any long period of time may be small.

Caa.  Bonds which are rated Caa are of poor standing.  Such 
issues may be in default or there may be present elements of 
danger with respect to principal or interest.

Ca.  Bonds which are rated Ca represent obligations which are 
speculative in a high degree.  Such issues are often in default 
or have other marked shortcomings.

C.  Bonds which are rated C are the lowest rated class of bonds 
and issues so rated can be regarded as having extremely poor 
prospects of ever attaining any real investment standing.

NOTE:  Moody's applies numerical modifiers 1, 2, and 3 in each 
generic rating classification from Aa through B in its corporate 
bond rating system.  The modifier 1 indicates that the security 
ranks in the higher end of its generic rating category; the 
modifier 2 indicates a mid-range ranking; and the modifier 3 
indicates that the issue ranks in the lower end of its generic 
rating category.

RATINGS BY S&P
AAA.  Debt rated AAA has the highest rating.  Capacity to pay 
interest and repay principal is extremely strong.

AA.  Debt rated AA has a very strong capacity to pay interest 
and repay principal and differs from the highest rated issues 
only in small degree.

A.  Debt rated A has a strong capacity to pay interest and repay 
principal although it is somewhat more susceptible to the 
adverse effects of changes in circumstances and economic 
conditions than debt in higher rated categories.

BBB.  Debt rated BBB is regarded as having an adequate capacity 
to pay interest and repay principal.  Whereas it normally 
exhibits adequate protection parameters, adverse economic 
conditions or changing circumstances are more likely to lead to 
a weakened capacity to pay interest and repay principal for debt 
in this category than for debt in higher rated categories.

BB, B, CCC, CC, and C.  Debt rated BB, B, CCC, CC, or C is 
regarded, on balance, as predominantly speculative with respect 
to capacity to pay interest and repay principal in accordance 
with the terms of the obligation.  BB indicates the lowest 
degree of speculation and C the highest degree of speculation.  
While such debt will likely have some quality and protective 
characteristics, these are outweighed by large uncertainties or 
major risk exposures to adverse conditions.

C1.  This rating is reserved for income bonds on which no 
interest is being paid.

D.  Debt rated D is in default, and payment of interest and/or 
repayment of principal is in arrears.  The D rating is also used 
upon the filing of a bankruptcy petition if debt service 
payments are jeopardized.

NOTES:  The ratings from AA to CCC may be modified by the 
addition of a plus (+) or minus (-) sign to show relative 
standing within the major rating categories.  Foreign debt is 
rated on the same basis as domestic debt measuring the 
creditworthiness of the issuer; ratings of foreign debt do not 
take into account currency exchange and related uncertainties.

The "r" is attached to highlight derivative, hybrid, and certain 
other obligations that S&P believes may experience high 
volatility or high variability in expected returns due to non-
credit risks.  Examples of such obligations are: securities 
whose principal or interest return is indexed to equities, 
commodities, or currencies; certain swaps and options; and 
interest only and principal only mortgage securities.  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.

COMMERCIAL PAPER RATINGS
RATINGS BY MOODY'S
Moody's employs the following three designations, all judged to 
be investment grade, to indicate the relative repayment capacity 
of rated issuers:

           Prime-1      Highest Quality
           Prime-2      Higher Quality
           Prime-3      High Quality

If an issuer represents to Moody's that its commercial paper 
obligations are supported by the credit of another entity or 
entities, Moody's, in assigning ratings to such issuers, 
evaluates the financial strength of the indicated affiliated 
corporations, commercial banks, insurance companies, foreign 
governments or other entities, but only as one factor in the 
total rating assessment.

RATINGS BY S&P
A brief description of the applicable rating symbols and their 
meaning follows:

A.  Issues assigned this highest rating are regarded as having 
the greatest capacity for timely payment.  Issues in this 
category are further refined with the designations 1, 2, and 3 
to indicate the relative degree of safety.

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

                GENERAL INFORMATION AND HISTORY

     Stein Roe Institutional High Yield Fund ("Institutional 
High Yield Fund") is a series of the Stein Roe Institutional 
Trust ("Institutional Trust").  Institutional High Yield Fund 
invests all of its net investable assets in shares of SR&F High 
Yield Portfolio ("High Yield Portfolio"), which is a series of 
shares of SR&F Base Trust ("Base Trust").

     Currently Institutional High Yield Fund is the only series 
of Institutional Trust authorized and outstanding.  Each share 
of a series is entitled to participate pro rata in any dividends 
and other distributions declared by the Board on shares of that 
series, and all shares of a series have equal rights in the 
event of liquidation of that series.  Each whole share (or 
fractional share) outstanding on the record date established in 
accordance with the By-Laws shall be entitled to a number of 
votes on any matter on which it is entitled to vote equal to the 
net asset value of the share (or fractional share) in United 
States dollars determined at the close of business on the record 
date (for example, a share having a net asset value of $10.50 
would be entitled to 10.5 votes).  As a business trust, 
Institutional Trust is not required to hold annual shareholder 
meetings.  However, special meetings may be called for purposes 
such as electing or removing trustees, changing fundamental 
policies, or approving an investment advisory contract.  If 
requested to do so by the holders of at least 10% of 
Institutional Trust's outstanding shares, Institutional Trust 
will call a special meeting for the purpose of voting upon the 
question of removal of a trustee or trustees and will assist in 
the communications with other shareholders as required by 
Section 16(c) of the Investment Company Act of 1940.  All shares 
of Institutional Trust are voted together in the election of 
trustees.  On any other matter submitted to a vote of 
shareholders, shares are voted by individual series and not in 
the aggregate, except that shares are voted in the aggregate 
when required by the Investment Company Act of 1940 or other 
applicable law.  When the Board of Trustees determines that the 
matter affects only the interests of one or more series, 
shareholders of the unaffected series are not entitled to vote 
on such matters.

     Stein Roe & Farnham Incorporated (the "Adviser") provides 
administrative and accounting and recordkeeping services to 
Institutional High Yield Fund and High Yield Portfolio and 
provides investment advisory services to High Yield Portfolio.

SPECIAL CONSIDERATIONS REGARDING MASTER FUND/FEEDER FUND 
STRUCTURE

     Rather than invest in securities directly, Institutional 
High Yield Fund seeks to achieve its objective by pooling its 
assets with assets of other investment companies and/or 
institutional investors for investment in another mutual fund 
having the same investment objective and substantially the same 
investment policies and restrictions.  The purpose of such an 
arrangement is to achieve greater operational efficiencies and 
reduce costs.  For more information, please refer to the 
Prospectus under the caption Special Considerations Regarding 
the Master Fund/Feeder Fund Structure.

                     INVESTMENT POLICIES

     The following information supplements the discussion of the 
investment objective and policies of Institutional High Yield 
Fund and High Yield Portfolio described in the Prospectus.  In 
pursuing its objective, High Yield Portfolio will invest as 
described below and may employ the investment techniques 
described in the Prospectus and in this Statement of Additional 
Information under Portfolio Investments and Strategies.  The 
investment objective is a non-fundamental policy and may be 
changed by the Board of Trustees without the approval of a 
"majority of the outstanding voting securities" /1/ of 
Institutional High Yield Fund or  High Yield Portfolio.
- -------------
/1/ A "majority of the outstanding voting securities" means the 
approval of the lesser of (i) 67% or more of the shares at a 
meeting if the holders of more than 50% of the outstanding 
shares are present or represented by proxy or (ii) more than 50% 
of the outstanding shares.
- ------------

     Institutional High Yield Fund seeks to achieve its 
objective by investing all of its assets in High Yield 
Portfolio.  The investment policies of Institutional High Yield 
Fund and High Yield Portfolio are substantially identical.  High 
Yield Portfolio seeks total return by investing for a high level 
of current income and capital growth.  

     High Yield Portfolio invests principally in high-yield, 
high-risk medium- and lower-quality debt securities.  The 
medium- and lower-quality debt securities in which High Yield 
Portfolio will invest normally offer a current yield or yield to 
maturity that is significantly higher than the yield from 
securities rated in the three highest categories assigned by 
rating services such as Standard & Poor's Corporation ("S&P") 
and by Moody's Investors Service, Inc. ("Moody's").

     Under normal circumstances, at least 65% of High Yield 
Portfolio's assets will be invested in high-yield, high-risk 
medium- and lower-quality debt securities rated lower than Baa 
by Moody's or lower than BBB by S&P, or equivalent ratings as 
determined by other rating agencies, or unrated securities that 
the Adviser determines to be of comparable quality.  Medium-
quality debt securities, although considered investment grade, 
have some speculative characteristics.  Lower-quality debt 
securities are obligations of issuers that are considered 
predominantly speculative with respect to the issuer's capacity 
to pay interest and repay principal according to the terms of 
the obligation and, therefore, carry greater investment risk, 
including the possibility of issuer default and bankruptcy, and 
are commonly referred to as "junk bonds." Some issuers of debt 
securities choose not to have their securities rated by a rating 
service, and High Yield Portfolio may invest in unrated 
securities that the Adviser has researched thoroughly and 
believes are suitable for investment.  High Yield Portfolio may 
invest in debt obligations that are in default, but such 
obligations are not expected to exceed 10% of High Yield 
Portfolio's assets.  

     High Yield Portfolio may invest up to 35% of its total 
assets in other securities including, but not limited to, pay-
in-kind bonds, securities issued in private placements, bank 
loans, zero coupon bonds, foreign securities, convertible 
securities, futures, and options.  High Yield Portfolio may also 
invest in higher-quality debt securities.  Under normal market 
conditions, however, High Yield Portfolio is unlikely to 
emphasize higher-quality debt securities since generally they 
offer lower yields than medium- and lower-quality debt 
securities with similar maturities.  High Yield Portfolio may 
also invest in common stocks and securities that are convertible 
into common stocks, such as warrants.

     Investment in medium- or lower-quality debt securities 
involves greater investment risk, including the possibility of 
issuer default or bankruptcy.  High Yield Portfolio seeks to 
reduce investment risk through diversification, credit analysis, 
and evaluation of developments in both the economy and financial 
markets.  

     An economic downturn could severely disrupt the high-yield 
market and adversely affect the value of outstanding bonds and 
the ability of the issuers to repay principal and interest.  In 
addition, lower-quality bonds are less sensitive to interest 
rate changes than higher-quality instruments (see Risks and 
Investment Considerations) and generally are more sensitive to 
adverse economic changes or individual corporate developments.  
During a period of adverse economic changes, including a period 
of rising interest rates, issuers of such bonds may experience 
difficulty in servicing their principal and interest payment 
obligations.

Achievement of the investment objective will be more dependent 
on the Adviser's credit analysis than would be the case if High 
Yield Portfolio were investing in higher-quality debt 
securities.  Since the ratings of rating services (which 
evaluate the safety of principal and interest payments, not 
market risks) are used only as preliminary indicators of 
investment quality, the Adviser employs its own credit research 
and analysis, from which it has developed a proprietary credit 
rating system based upon comparative credit analyses of issuers 
within the same industry.  These analyses may take into 
consideration such quantitative factors as an issuer's present 
and potential liquidity, profitability, internal capability to 
generate funds, debt/equity ratio and debt servicing 
capabilities, and such qualitative factors as an assessment of 
management, industry characteristics, accounting methodology, 
and foreign business exposure.

     Lower-quality debt securities are obligations of issuers 
that are considered predominantly speculative with respect to 
the issuer's capacity to pay interest and repay principal 
according to the terms of the obligation and, therefore, carry 
greater investment risk, including the possibility of issuer 
default and bankruptcy, and are commonly referred to as "junk 
bonds."  The lowest rating assigned by Moody's is for bonds that 
can be regarded as having extremely poor prospects of ever 
attaining any real investment standing.  

     Medium- and lower-quality debt securities tend to be less 
marketable than higher-quality debt securities because the 
market for them is less broad.  The market for unrated debt 
securities is even narrower.  During periods of thin trading in 
these markets, the spread between bid and asked prices is likely 
to increase significantly, and High Yield Portfolio may have 
greater difficulty selling its portfolio securities.  The market 
value of these securities and their liquidity may be affected by 
adverse publicity and investor perceptions.

              PORTFOLIO INVESTMENTS AND STRATEGIES

DERIVATIVES

     Consistent with its objective, High Yield Portfolio may 
invest in a broad array of financial instruments and securities, 
including conventional exchange-traded and non-exchange traded 
options, futures contracts, futures options, securities 
collateralized by underlying pools of mortgages or other 
receivables, and other instruments the value of which is 
"derived" from the performance of an underlying asset or a 
"benchmark" such as a security index, an interest rate, or a 
currency ("Derivatives").

     Derivatives are most often used to manage investment risk 
or to create an investment position indirectly because it is 
more efficient or less costly than direct investment that cannot 
be readily established directly due to portfolio size, cash 
availability, or other factors.  They also may be used in an 
effort to enhance portfolio returns.

     The successful use of Derivatives depends on the Adviser's 
ability to correctly predict changes in the levels and 
directions of movements in security prices, interest rates and 
other market factors affecting the Derivative itself or the 
value of the underlying asset or benchmark.  In addition, 
correlations in the performance of an underlying asset to a 
Derivative may not be well established.  Finally, privately 
negotiated and over-the-counter Derivatives may not be as well 
regulated and may be less marketable than exchange-traded 
Derivatives.

     High Yield Portfolio does not intend to invest more than 5% 
of its assets in any type of Derivative except for options, 
futures contracts, and futures options.

MORTGAGE AND OTHER ASSET-BACKED SECURITIES

     High Yield Portfolio may invest in securities secured by 
mortgages or other assets such as automobile or home improvement 
loans and credit card receivables.  These instruments may be 
issued or guaranteed by the U.S. Government or by its agencies 
or instrumentalities or by private entities such as commercial, 
mortgage and investment banks and financial companies or 
financial subsidiaries of industrial companies.

     Mortgage-backed securities provide either a pro rata 
interest in underlying mortgages or an interest in 
collateralized mortgage obligations ("CMOs") which represent a 
right to interest and/or principal payments from an underlying 
mortgage pool.  CMOs are not guaranteed by either the U.S. 
Government or by its agencies or instrumentalities, and are 
usually issued in multiple classes each of which has different 
payment rights, pre-payment risks and yield characteristics.  
Mortgage-backed securities involve the risk of pre-payment on 
the underlying mortgages at a faster or slower rate than the 
established schedule.  Pre-payments generally increase with 
falling interest rates and decrease with rising rates but they 
also are influenced by economic, social and market factors.  If 
mortgages are pre-paid during periods of declining interest 
rates, there would be a resulting loss of the full-term benefit 
of any premium paid by High Yield Portfolio on purchase of the 
CMO, and the proceeds of pre-payment would likely be invested at 
lower interest rates.  High Yield Portfolio intends to invest in 
CMOs of classes known as planned amortization classes ("PACs") 
which have pre-payment protection features tending to make them 
less susceptible to price volatility.

     Non-mortgage asset-backed securities usually have less pre-
payment risk than mortgage-backed securities, but have the risk 
that the collateral will not be available to support payments on 
the underlying loans which finance payments on the securities 
themselves.  Therefore, greater emphasis is placed on the credit 
quality of the security issuer and the guarantor, if any.

FLOATING RATE INSTRUMENTS

     High Yield Portfolio may also invest in floating rate 
instruments which provide for periodic adjustments in coupon 
interest rates that are automatically reset based on changes in 
amount and direction of specified market interest rates.  In 
addition, the adjusted duration of some of these instruments may 
be materially shorter than their stated maturities.  To the 
extent such instruments are subject to lifetime or periodic 
interest rate caps or floors, such instruments may experience 
greater price volatility than debt instruments without such 
features.  Adjusted duration is an inverse relationship between 
market price and interest rates and refers to the approximate 
percentage change in price for a 100 basis point change in 
yield.  For example, if interest rates decrease by 100 basis 
points, a market price of a security with an adjusted duration 
of 2 would increase by approximately 2%.  High Yield Portfolio 
does not intend to invest more than 5% of its net assets in 
floating rate instruments.

LENDING OF PORTFOLIO SECURITIES

     Subject to restriction (7) under Investment Restrictions, 
High Yield Portfolio may lend its portfolio securities to 
broker-dealers and banks.  Any such loan must be continuously 
secured by collateral in cash or cash equivalents maintained on 
a current basis in an amount at least equal to the market value 
of the securities loaned by High Yield Portfolio.  High Yield 
Portfolio would continue to receive the equivalent of the 
interest or dividends paid by the issuer on the securities 
loaned, and would also receive an additional return that may be 
in the form of a fixed fee or a percentage of the collateral.  
High Yield Portfolio would have the right to call the loan and 
obtain the securities loaned at any time on notice of not more 
than five business days.  In the event of bankruptcy or other 
default of the borrower, High Yield Portfolio could experience 
both delays in liquidating the loan collateral or recovering the 
loaned securities and losses including (a) possible decline in 
the value of the collateral or in the value of the securities 
loaned during the period while High Yield Portfolio seeks to 
enforce its rights thereto, (b) possible subnormal levels of 
income and lack of access to income during this period, and (c) 
expenses of enforcing its rights.

WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES; REVERSE REPURCHASE 
AGREEMENTS; STANDBY COMMITMENTS

     High Yield Portfolio may purchase instruments on a when-
issued or delayed-delivery basis.  Although payment terms are 
established at the time High Yield Portfolio enters into the 
commitment, the instruments may be delivered and paid for some 
time after the date of purchase, when their value may have 
changed and the yields available in the market may be greater.  
High Yield Portfolio will make such commitments only with the 
intention of actually acquiring the instruments, but may sell 
them before settlement date if it is deemed advisable for 
investment reasons.  Securities purchased in this manner involve 
risk of loss if the value of the security purchased declines 
before settlement date.

     High Yield Portfolio may purchase securities on a when-
issued or delayed-delivery basis, as described in the 
Prospectus.  High Yield Portfolio makes such commitments only 
with the intention of actually acquiring the securities, but may 
sell the securities before settlement date if the Adviser deems 
it advisable for investment reasons.  Securities purchased on a 
when-issued or delayed-delivery basis are sometimes done on a 
"dollar roll" basis.  Dollar roll transactions consist of the 
sale by High Yield Portfolio of securities with a commitment to 
purchase similar but not identical securities, generally at a 
lower price at a future date.  A dollar roll may be renewed 
after cash settlement and initially may involve only a firm 
commitment agreement by High Yield Portfolio to buy a security.  
A dollar roll transaction involves the following risks: if the 
broker-dealer to whom High Yield Portfolio sells the security 
becomes insolvent, High Yield Portfolio's right to purchase or 
repurchase the security may be restricted; the value of the 
security may change adversely over the term of the dollar roll; 
the security which High Yield Portfolio is required to 
repurchase may be worth less than a security which High Yield 
Portfolio originally held; and the return earned by High Yield 
Portfolio with the proceeds of a dollar roll may not exceed 
transaction costs.

     High Yield Portfolio may enter into reverse repurchase 
agreements with banks and securities dealers.  A reverse 
repurchase agreement is a repurchase agreement in which High 
Yield Portfolio is the seller of, rather than the investor in, 
securities and agrees to repurchase them at an agreed-upon time 
and price.  Use of a reverse repurchase agreement may be 
preferable to a regular sale and later repurchase of securities 
because it avoids certain market risks and transaction costs.

     At the time High Yield Portfolio enters into a binding 
obligation to purchase securities on a when-issued basis or 
enters into a reverse repurchase agreement, liquid assets (cash, 
U.S. Government or other "high grade" debt obligations) of High 
Yield Portfolio having a value at least as great as the purchase 
price of the securities to be purchased will be segregated on 
the books of High Yield Portfolio and held by the custodian 
throughout the period of the obligation.  The use of these 
investment strategies, as well as borrowing under a line of 
credit as described below, may increase net asset value 
fluctuation.

     Standby commitment agreements create an additional risk for 
High Yield Portfolio because the other party to the standby 
agreement generally will not be obligated to deliver the 
security, but High Yield Portfolio will be obligated to accept 
it if delivered.  Depending on market conditions, High Yield 
Portfolio may receive a commitment fee for assuming this 
obligation.  If prevailing market interest rates increase during 
the period between the date of the agreement and the settlement 
date, the other party can be expected to deliver the security 
and, in effect, pass any decline in value to High Yield 
Portfolio.  If the value of the security increases after the 
agreement is made, however, the other party is unlikely to 
deliver the security.  In other words, a decrease in the value 
of the securities to be purchased under the terms of a standby 
commitment agreement will likely result in the delivery of the 
security, and, therefore, such decrease will be reflected in 
High Yield Portfolio's net asset value.  However, any increase 
in the value of the securities to be purchased will likely 
result in the non-delivery of the security and, therefore, such 
increase will not affect the net asset value unless and until 
High Yield Portfolio actually obtains the security.

SHORT SALES AGAINST THE BOX

     High Yield Portfolio may sell securities short against the 
box; that is, enter into short sales of securities that it 
currently owns or has the right to acquire through the 
conversion or exchange of other securities that it owns at no 
additional cost.  High Yield Portfolio may make short sales of 
securities only if at all times when a short position is open 
High Yield Portfolio owns at least an equal amount of such 
securities or securities convertible into or exchangeable for 
securities of the same issue as, and equal in amount to, the 
securities sold short, at no additional cost.

     In a short sale against the box, High Yield Portfolio does 
not deliver from its portfolio the securities sold.   Instead, 
High Yield Portfolio borrows the securities sold short from a 
broker-dealer through which the short sale is executed, and the 
broker-dealer delivers such securities, on behalf of High Yield 
Portfolio, to the purchaser of such securities.  High Yield 
Portfolio is required to pay to the broker-dealer the amount of 
any dividends paid on shares sold short.  Finally, to secure its 
obligation to deliver to such broker-dealer the securities sold 
short, High Yield Portfolio must deposit and continuously 
maintain in a separate account with High Yield Portfolio's 
custodian an equivalent amount of the securities sold short or 
securities convertible into or exchangeable for such securities 
at no additional cost.  High Yield Portfolio is said to have a 
short position in the securities sold until it delivers to the 
broker-dealer the securities sold.  High Yield Portfolio may 
close out a short position by purchasing on the open market and 
delivering to the broker-dealer an equal amount of the 
securities sold short, rather than by delivering portfolio 
securities.

     Short sales may protect High Yield Portfolio against the 
risk of losses in the value of its portfolio securities because 
any unrealized losses with respect to such portfolio securities 
should be wholly or partially offset by a corresponding gain in 
the short position.  However, any potential gains in such 
portfolio securities should be wholly or partially offset by a 
corresponding loss in the short position.  The extent to which 
such gains or losses are offset will depend upon the amount of 
securities sold short relative to the amount High Yield 
Portfolio owns, either directly or indirectly, and, in the case 
where High Yield Portfolio owns convertible securities, changes 
in the conversion premium.

     Short sale transactions involve certain risks.  If the 
price of the security sold short increases between the time of 
the short sale and the time High Yield Portfolio replaces the 
borrowed security, High Yield Portfolio will incur a loss and if 
the price declines during this period, High Yield Portfolio will 
realize a short-term capital gain.  Any realized short-term 
capital gain will be decreased, and any incurred loss increased, 
by the amount of transaction costs and any premium, dividend or 
interest which High Yield Portfolio may have to pay in 
connection with such short sale.  Certain provisions of the 
Internal Revenue Code may limit the degree to which High Yield 
Portfolio is able to enter into short sales.  There is no 
limitation on the amount of High Yield Portfolio's assets that, 
in the aggregate, may be deposited as collateral for the 
obligation to replace securities borrowed to effect short sales 
and allocated to segregated accounts in connection with short 
sales.  High Yield Portfolio currently expects that no more than 
5% of its total assets would be involved in short sales against 
the box.

LINE OF CREDIT

     Subject to restriction (8) under Investment Restrictions, 
High Yield Portfolio may establish and maintain a line of credit 
with a major bank in order to permit borrowing on a temporary 
basis to meet share redemption requests in circumstances in 
which temporary borrowing may be preferable to liquidation of 
portfolio securities.

INTERFUND BORROWING AND LENDING PROGRAM

     Pursuant to an exemptive order issued by the Securities and 
Exchange Commission, Institutional High Yield Fund has received 
permission to lend money to, and borrow money from, other mutual 
funds advised by the Adviser.  Institutional High Yield Fund 
will borrow through the program when the costs are equal to or 
lower than the costs of bank loans.

PIK AND ZERO COUPON BONDS

     High Yield Portfolio may invest up to 20% of its assets in 
zero coupon bonds and bonds the interest on which is payable in 
kind ("PIK bonds").  A zero coupon bond is a bond that does not 
pay interest for its entire life.  A PIK bond pays interest in 
the form of additional securities.  The market prices of both 
zero coupon and PIK bonds are affected to a greater extent by 
changes in prevailing levels of interest rates and thereby tend 
to be more volatile in price than securities that pay interest 
periodically and in cash.  In addition, because High Yield 
Portfolio accrues income with respect to these securities prior 
to the receipt of such interest in cash, it may have to dispose 
of portfolio securities under disadvantageous circumstances in 
order to obtain cash needed to pay income dividends in amounts 
necessary to avoid unfavorable tax consequences.  

RATED SECURITIES

     For a description of the ratings applied by rating services 
to debt securities, please refer to the Appendix.  The rated 
debt securities described under Investment Policies above for 
High Yield Portfolio include securities given a rating 
conditionally by Moody's or provisionally by S&P.  If the rating 
of a security held by High Yield Portfolio is withdrawn or 
reduced, High Yield Portfolio is not required to sell the 
security, but the Adviser will consider such fact in determining 
whether High Yield Portfolio should continue to hold the 
security.  To the extent that the ratings accorded by Moody's or 
S&P for debt securities may change as a result of changes in 
such organizations, or changes in their rating systems, High 
Yield Portfolio will attempt to use comparable ratings as 
standards for its investments in debt securities in accordance 
with its investment policies.

FOREIGN SECURITIES

     High Yield Portfolio may invest up to 25% of total assets 
(taken at market value at the time of investment) in securities 
of foreign issuers that are not publicly traded in the United 
States ("foreign securities").  For purposes of these limits, 
foreign securities do not include securities represented by 
American Depositary Receipts ("ADRs"), securities denominated in 
U.S. dollars, or securities guaranteed by U.S. persons.  
Investment in foreign securities may involve a greater degree of 
risk (including risks relating to exchange fluctuations, tax 
provisions, or expropriation of assets) than does investment in 
securities of domestic issuers.

     High Yield Portfolio may invest in both "sponsored" and 
"unsponsored" ADRs.  In a sponsored ADR, the issuer typically 
pays some or all of the expenses of the depositary and agrees to 
provide its regular shareholder communications to ADR holders.  
An unsponsored ADR is created independently of the issuer of the 
underlying security.  The ADR holders generally pay the expenses 
of the depositary and do not have an undertaking from the issuer 
of the underlying security to furnish shareholder 
communications.  High Yield Portfolio does not expects to invest 
as much as 5% of its total assets in unsponsored ADRs.

     With respect to portfolio securities that are issued by 
foreign issuers or denominated in foreign currencies, High Yield 
Portfolio's investment performance is affected by the strength 
or weakness of the U.S. dollar against these currencies.  For 
example, if the dollar falls in value relative to the Japanese 
yen, the dollar value of a yen-denominated stock held in the 
investment portfolio will rise even though the price of the 
stock remains unchanged.  Conversely, if the dollar rises in 
value relative to the yen, the dollar value of the yen-
denominated stock will fall.  (See discussion of transaction 
hedging and portfolio hedging under Currency Exchange 
Transactions.)

     Investors should understand and consider carefully the 
risks involved in foreign investing.  Investing in foreign 
securities, positions in which are generally denominated in 
foreign currencies, and utilization of forward foreign currency 
exchange contracts involve certain considerations comprising 
both risks and opportunities not typically associated with 
investing in U.S. securities.  These considerations include:  
fluctuations in exchange rates of foreign currencies; possible 
imposition of exchange control regulation or currency 
restrictions that would prevent cash from being brought back to 
the United States; less public information with respect to 
issuers of securities; less governmental supervision of stock 
exchanges, securities brokers, and issuers of securities; lack 
of uniform accounting, auditing, and financial reporting 
standards; lack of uniform settlement periods and trading 
practices; less liquidity and frequently greater price 
volatility in foreign markets than in the United States; 
possible imposition of foreign taxes; possible investment in 
securities of companies in developing as well as developed 
countries; and sometimes less advantageous legal, operational, 
and financial protections applicable to foreign sub-custodial 
arrangements.

     Although High Yield Portfolio will try to invest in 
companies and governments of countries having stable political 
environments, there is the possibility of expropriation or 
confiscatory taxation, seizure or nationalization of foreign 
bank deposits or other assets, establishment of exchange 
controls, the adoption of foreign government restrictions, or 
other adverse political, social or diplomatic developments that 
could affect investment in these nations.

     Currency Exchange Transactions.  Currency exchange 
transactions may be conducted either on a spot (i.e., cash) 
basis at the spot rate for purchasing or selling currency 
prevailing in the foreign exchange market or through forward 
currency exchange contracts ("forward contracts").  Forward 
contracts are contractual agreements to purchase or sell a 
specified currency at a specified future date (or within a 
specified time period) and price set at the time of the 
contract.  Forward contracts are usually entered into with banks 
and broker-dealers, are not exchange traded, and are usually for 
less than one year, but may be renewed.

     High Yield Portfolio's foreign currency exchange 
transactions are limited to transaction and portfolio hedging 
involving either specific transactions or portfolio positions, 
except to the extent described below under Synthetic Foreign 
Positions.  Transaction hedging is the purchase or sale of 
forward contracts with respect to specific receivables or 
payables of High Yield Portfolio arising in connection with the 
purchase and sale of its portfolio securities.  Portfolio 
hedging is the use of forward contracts with respect to 
portfolio security positions denominated or quoted in a 
particular foreign currency.  Portfolio hedging allows High 
Yield Portfolio to limit or reduce its exposure in a foreign 
currency by entering into a forward contract to sell such 
foreign currency (or another foreign currency that acts as a 
proxy for that currency) at a future date for a price payable in 
U.S. dollars so that the value of the foreign-denominated 
portfolio securities can be approximately matched by a foreign-
denominated liability.  High Yield Portfolio may not engage in 
portfolio hedging with respect to the currency of a particular 
country to an extent greater than the aggregate market value (at 
the time of making such sale) of the securities held in its 
portfolio denominated or quoted in that particular currency, 
except that High Yield Portfolio may hedge all or part of its 
foreign currency exposure through the use of a basket of 
currencies or a proxy currency where such currencies or currency 
act as an effective proxy for other currencies.  In such a case, 
High Yield Portfolio may enter into a forward contract where the 
amount of the foreign currency to be sold exceeds the value of 
the securities denominated in such currency.  The use of this 
basket hedging technique may be more efficient and economical 
than entering into separate forward contracts for each currency 
held in High Yield Portfolio.  High Yield Portfolio may not 
engage in "speculative" currency exchange transactions.

     At the maturity of a forward contract to deliver a 
particular currency, High Yield Portfolio may either sell the 
portfolio security related to such contract and make delivery of 
the currency, or it may retain the security and either acquire 
the currency on the spot market or terminate its contractual 
obligation to deliver the currency by purchasing an offsetting 
contract with the same currency trader obligating it to purchase 
on the same maturity date the same amount of the currency.

     It is impossible to forecast with absolute precision the 
market value of portfolio securities at the expiration of a 
forward contract.  Accordingly, it may be necessary for High 
Yield Portfolio to purchase additional currency on the spot 
market (and bear the expense of such purchase) if the market 
value of the security is less than the amount of currency High 
Yield Portfolio is obligated to deliver and if a decision is 
made to sell the security and make delivery of the currency.  
Conversely, it may be necessary to sell on the spot market some 
of the currency received upon the sale of the portfolio security 
if its market value exceeds the amount of currency High Yield 
Portfolio is obligated to deliver.

     If High Yield Portfolio retains the portfolio security and 
engages in an offsetting transaction, High Yield Portfolio will 
incur a gain or a loss to the extent that there has been 
movement in forward contract prices.  If High Yield Portfolio 
engages in an offsetting transaction, it may subsequently enter 
into a new forward contract to sell the currency.  Should 
forward prices decline during the period between High Yield 
Portfolio's entering into a forward contract for the sale of a 
currency and the date it enters into an offsetting contract for 
the purchase of the currency, High Yield Portfolio will realize 
a gain to the extent the price of the currency it has agreed to 
sell exceeds the price of the currency it has agreed to 
purchase.  Should forward prices increase, High Yield Portfolio 
will suffer a loss to the extent the price of the currency it 
has agreed to purchase exceeds the price of the currency it has 
agreed to sell.  A default on the contract would deprive High 
Yield Portfolio of unrealized profits or force High Yield 
Portfolio to cover its commitments for purchase or sale of 
currency, if any, at the current market price.

     Hedging against a decline in the value of a currency does 
not eliminate fluctuations in the prices of portfolio securities 
or prevent losses if the prices of such securities decline.  
Such transactions also preclude the opportunity for gain if the 
value of the hedged currency should rise.  Moreover, it may not 
be possible for High Yield Portfolio to hedge against a 
devaluation that is so generally anticipated that High Yield 
Portfolio is not able to contract to sell the currency at a 
price above the devaluation level it anticipates.  The cost to 
High Yield Portfolio of engaging in currency exchange 
transactions varies with such factors as the currency involved, 
the length of the contract period, and prevailing market 
conditions.  Since currency exchange transactions are usually 
conducted on a principal basis, no fees or commissions are 
involved.

     Synthetic Foreign Positions.  High Yield Portfolio may 
invest in debt instruments denominated in foreign currencies.  
In addition to, or in lieu of, such direct investment, High 
Yield Portfolio may construct a synthetic foreign position by 
(a) purchasing a debt instrument denominated in one currency, 
generally U.S. dollars, and (b) concurrently entering into a 
forward contract to deliver a corresponding amount of that 
currency in exchange for a different currency on a future date 
and at a specified rate of exchange.  Because of the 
availability of a variety of highly liquid U.S. dollar debt 
instruments, a synthetic foreign position utilizing such U.S. 
dollar instruments may offer greater liquidity than direct 
investment in foreign currency debt instruments.  The results of 
a direct investment in a foreign currency and a concurrent 
construction of a synthetic position in such foreign currency, 
in terms of both income yield and gain or loss from changes in 
currency exchange rates, in general should be similar, but would 
not be identical because the components of the alternative 
investments would not be identical.

     High Yield Portfolio may also construct a synthetic foreign 
position by entering into a swap arrangement.  A swap is a 
contractual agreement between two parties to exchange cash 
flows--at the time of the swap agreement and again at maturity, 
and, with some swaps, at various intervals through the period of 
the agreement.  The use of swaps to construct a synthetic 
foreign position would generally entail the swap of interest 
rates and currencies.  A currency swap is a contractual 
arrangement between two parties to exchange principal amounts in 
different currencies at a predetermined foreign exchange rate.  
An interest rate swap is a contractual agreement between two 
parties to exchange interest payments on identical principal 
amounts.  An interest rate swap may be between a floating and a 
fixed rate instrument, a domestic and a foreign instrument, or 
any other type of cash flow exchange.  A currency swap generally 
has the same risk characteristics as a forward currency 
contract, and all types of swaps have counter-party risk.  
Depending on the facts and circumstances, swaps may be 
considered illiquid.  Illiquid securities usually have greater 
investment risk and are subject to greater price volatility.  
The net amount of the excess, if any, of High Yield Portfolio's 
obligations over which it is entitled to receive with respect to 
an interest rate or currency swap will be accrued daily and 
liquid assets (cash, U.S. Government securities, or other "high 
grade" debt obligations) of High Yield Portfolio having a value 
at least equal to such accrued excess will be segregated on the 
books of High Yield Portfolio and held by the Custodian for the 
duration of the swap.

     High Yield Portfolio may also construct a synthetic foreign 
position by purchasing an instrument whose return is tied to the 
return of the desired foreign position.  An investment in these 
"principal exchange rate linked securities" (often called PERLS) 
can produce a similar return to a direct investment in a foreign 
security.

RULE 144A SECURITIES

     High Yield Portfolio may purchase securities that have been 
privately placed but that are eligible for purchase and sale 
under Rule 144A under the 1933 Act.  That Rule permits certain 
qualified institutional buyers, such as High Yield Portfolio, to 
trade in privately placed securities that have not been 
registered for sale under the 1933 Act.  The Adviser, under the 
supervision of the Board of Trustees, will consider whether 
securities purchased under Rule 144A are illiquid and thus 
subject to High Yield Portfolio's restriction of investing no 
more than 10% of its net assets in illiquid securities.  A 
determination of whether a Rule 144A security is liquid or not 
is a question of fact.  In making this determination, the 
Adviser will consider the trading markets for the specific 
security, taking into account the unregistered nature of a Rule 
144A security.  In addition, the Adviser could consider the (1) 
frequency of trades and quotes, (2) number of dealers and 
potential purchasers, (3) dealer undertakings to make a market, 
and (4) nature of the security and of marketplace trades (e.g., 
the time needed to dispose of the security, the method of 
soliciting offers, and the mechanics of transfer).  The 
liquidity of Rule 144A securities would be monitored and, if as 
a result of changed conditions, it is determined that a Rule 
144A security is no longer liquid, High Yield Portfolio's 
holdings of illiquid securities would be reviewed to determine 
what, if any, steps are required to assure that High Yield 
Portfolio does not invest more than 10% of its assets in 
illiquid securities.  Investing in Rule 144A securities could 
have the effect of increasing the amount of High Yield 
Portfolio's assets invested in illiquid securities if qualified 
institutional buyers are unwilling to purchase such securities.  
High Yield Portfolio does not expect to invest as much as 5% of 
its total assets in Rule 144A securities that have not been 
deemed to be liquid by the Adviser.

PORTFOLIO TURNOVER

     The turnover rate for High Yield Portfolio in the future 
may vary greatly from year to year, and when portfolio changes 
are deemed appropriate due to market or other conditions, such 
turnover rate may be greater than might otherwise be 
anticipated.  A high rate of portfolio turnover may result in 
increased transaction expenses and the realization of capital 
gains or losses.  Distributions of any net realized gains are 
subject to federal income tax.  (See Risks and Investment 
Considerations and Distributions and Income Taxes in the 
Prospectus, and Additional Income Tax Considerations in this 
Statement of Additional Information.)

OPTIONS ON SECURITIES AND INDEXES

     High Yield Portfolio may purchase and may sell both put 
options and call options on debt or other securities or indexes 
in standardized contracts traded on national securities 
exchanges, boards of trade, or similar entities, or quoted on 
NASDAQ, and agreements, sometimes called cash puts, that may 
accompany the purchase of a new issue of bonds from a dealer.

     An option on a security (or index) is a contract that gives 
the purchaser (holder) of the option, in return for a premium, 
the right to buy from (call) or sell to (put) the seller 
(writer) of the option the security underlying the option (or 
the cash value of the index) at a specified exercise price at 
any time during the term of the option.  The writer of an option 
on an individual security has the obligation upon exercise of 
the option to deliver the underlying security upon payment of 
the exercise price or to pay the exercise price upon delivery of 
the underlying security.  Upon exercise, the writer of an option 
on an index is obligated to pay the difference between the cash 
value of the index and the exercise price multiplied by the 
specified multiplier for the index option.  (An index is 
designed to reflect specified facets of a particular financial 
or securities market, a specific group of financial instruments 
or securities, or certain economic indicators.)

     High Yield Portfolio will write call options and put 
options only if they are "covered."  In the case of a call 
option on a security, the option is "covered" if High Yield 
Portfolio owns the security underlying the call or has an 
absolute and immediate right to acquire that security without 
additional cash consideration (or, if additional cash 
consideration is required, cash or cash equivalents in such 
amount are held in a segregated account by its custodian) upon 
conversion or exchange of other securities held in its 
portfolio.

     If an option written by High Yield Portfolio expires, High 
Yield Portfolio realizes a capital gain equal to the premium 
received at the time the option was written.  If an option 
purchased by High Yield Portfolio expires, High Yield Portfolio 
realizes a capital loss equal to the premium paid.

     Prior to the earlier of exercise or expiration, an option 
may be closed out by an offsetting purchase or sale of an option 
of the same series (type, exchange, underlying security or 
index, exercise price, and expiration).  There can be no 
assurance, however, that a closing purchase or sale transaction 
can be effected when High Yield Portfolio desires.

     High Yield Portfolio will realize a capital gain from a 
closing purchase transaction if the cost of the closing option 
is less than the premium received from writing the option, or, 
if it is more, High Yield Portfolio will realize a capital loss.  
If the premium received from a closing sale transaction is more 
than the premium paid to purchase the option, High Yield 
Portfolio will realize a capital gain or, if it is less, High 
Yield Portfolio will realize a capital loss.  The principal 
factors affecting the market value of a put or a call option 
include supply and demand, interest rates, the current market 
price of the underlying security or index in relation to the 
exercise price of the option, the volatility of the underlying 
security or index, and the time remaining until the expiration 
date.

     A put or call option purchased by High Yield Portfolio is 
an asset of High Yield Portfolio, valued initially at the 
premium paid for the option.  The premium received for an option 
written by High Yield Portfolio is recorded as a deferred 
credit.  The value of an option purchased or written is marked-
to-market daily and is valued at the closing price on the 
exchange on which it is traded or, if not traded on an exchange 
or no closing price is available, at the mean between the last 
bid and asked prices.

     Risks Associated with Options on Securities and Indexes.  
There are several risks associated with transactions in options 
on securities and on indexes.  For example, there are 
significant differences between the securities markets and 
options markets that could result in an imperfect correlation 
between these markets, causing a given transaction not to 
achieve its objectives.  A decision as to whether, when and how 
to use options involves the exercise of skill and judgment, and 
even a well-conceived transaction may be unsuccessful to some 
degree because of market behavior or unexpected events.

     There can be no assurance that a liquid market will exist 
when High Yield Portfolio seeks to close out an option position.  
If High Yield Portfolio were unable to close out an option that 
it had purchased on a security, it would have to exercise the 
option in order to realize any profit or the option would expire 
and become worthless.  If High Yield Portfolio were unable to 
close out a covered call option that it had written on a 
security, it would not be able to sell the underlying security 
until the option expired.  As the writer of a covered call 
option, High Yield Portfolio foregoes, during the option's life, 
the opportunity to profit from increases in the market value of 
the security covering the call option above the sum of the 
premium and the exercise price of the call.

     If trading were suspended in an option purchased by High 
Yield Portfolio, High Yield Portfolio would not be able to close 
out the option.  If restrictions on exercise were imposed, High 
Yield Portfolio might be unable to exercise an option it has 
purchased.  

FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

     High Yield Portfolio may use interest rate futures 
contracts and index futures contracts.  An interest rate or 
index futures contract provides for the future sale by one party 
and purchase by another party of a specified quantity of a 
financial instrument or the cash value of an index /2/ at a 
specified price and time.  A public market exists in futures 
contracts covering a number of indexes as well as the following 
financial instruments: U.S. Treasury bonds; U.S. Treasury notes; 
GNMA Certificates; three-month U.S. Treasury bills; 90-day 
commercial paper; bank certificates of deposit; Eurodollar 
certificates of deposit; and foreign currencies.  It is expected 
that other futures contracts will be developed and traded.
- --------------
/2/A futures contract on an index is an agreement pursuant to 
which two parties agree to take or make delivery of an amount of 
cash equal to the difference between the value of the index at 
the close of the last trading day of the contract and the price 
at which the index contract was originally written.  Although 
the value of a securities index is a function of the value of 
certain specified securities, no physical delivery of those 
securities is made.

- --------------

     High Yield Portfolio may purchase and write call and put 
futures options.  Futures options possess many of the same 
characteristics as options on securities and indexes (discussed 
above).  A futures option gives the holder the right, in return 
for the premium paid, to assume a long position (call) or short 
position (put) in a futures contract at a specified exercise 
price at any time during the period of the option.  Upon 
exercise of a call option, the holder acquires a long position 
in the futures contract and the writer is assigned the opposite 
short position.  In the case of a put option, the opposite is 
true.  High Yield Portfolio might, for example, use futures 
contracts to hedge against or gain exposure to fluctuations in 
the general level of security prices, anticipated changes in 
interest rates or currency fluctuations that might adversely 
affect either the value of High Yield Portfolio's securities or 
the price of the securities that High Yield Portfolio intends to 
purchase.  Although other techniques could be used to reduce 
High Yield Portfolio's exposure to security price, interest rate 
and currency fluctuations, High Yield Portfolio may be able to 
achieve its exposure more effectively and perhaps at a lower 
cost by using futures contracts and futures options.

     High Yield Portfolio will only enter into futures contracts 
and futures options that are standardized and traded on an 
exchange, board of trade, or similar entity, or quoted on an 
automated quotation system.

     The success of any futures transaction depends on the 
Adviser correctly predicting changes in the level and direction 
of security prices, interest rates, currency exchange rates and 
other factors.  Should those predictions be incorrect, High 
Yield Portfolio's return might have been better had the 
transaction not been attempted; however, in the absence of the 
ability to use futures contracts, the Adviser might have taken 
portfolio actions in anticipation of the same market movements 
with similar investment results but, presumably, at greater 
transaction costs.

     When a purchase or sale of a futures contract is made by 
High Yield Portfolio, High Yield Portfolio is required to 
deposit with its custodian (or broker, if legally permitted) a 
specified amount of cash or U.S. Government securities or other 
securities acceptable to the broker ("initial margin").  The 
margin required for a futures contract is set by the exchange on 
which the contract is traded and may be modified during the term 
of the contract.  The initial margin is in the nature of a 
performance bond or good faith deposit on the futures contract 
that is returned to High Yield Portfolio upon termination of the 
contract, assuming all contractual obligations have been 
satisfied.  High Yield Portfolio expects to earn interest income 
on its initial margin deposits.  A futures contract held by High 
Yield Portfolio is valued daily at the official settlement price 
of the exchange on which it is traded.  Each day High Yield 
Portfolio pays or receives cash, called "variation margin," 
equal to the daily change in value of the futures contract.  
This process is known as "marking-to-market."  Variation margin 
paid or received by High Yield Portfolio does not represent a 
borrowing or loan by High Yield Portfolio but is instead 
settlement between High Yield Portfolio and the broker of the 
amount one would owe the other if the futures contract had 
expired at the close of the previous trading day.  In computing 
daily net asset value, High Yield Portfolio will mark-to-market 
its open futures positions.

     High Yield Portfolio is also required to deposit and 
maintain margin with respect to put and call options on futures 
contracts written by it.  Such margin deposits will vary 
depending on the nature of the underlying futures contract (and 
the related initial margin requirements), the current market 
value of the option, and other futures positions held by High 
Yield Portfolio.

     Although some futures contracts call for making or taking 
delivery of the underlying securities, usually these obligations 
are closed out prior to delivery by offsetting purchases or 
sales of matching futures contracts (same exchange, underlying 
security or index, and delivery month).  If an offsetting 
purchase price is less than the original sale price, High Yield 
Portfolio realizes a capital gain, or if it is more, High Yield 
Portfolio realizes a capital loss.  Conversely, if an offsetting 
sale price is more than the original purchase price, High Yield 
Portfolio realizes a capital gain, or if it is less, High Yield 
Portfolio realizes a capital loss.  The transaction costs must 
also be included in these calculations.

RISKS ASSOCIATED WITH FUTURES

     There are several risks associated with the use of futures 
contracts and futures options as hedging techniques.  A purchase 
or sale of a futures contract may result in losses in excess of 
the amount invested in the futures contract.  In trying to 
increase or reduce market exposure, there can be no guarantee 
that there will be a correlation between price movements in the 
futures contract and in the portfolio exposure sought.  In 
addition, there are significant differences between the 
securities and futures markets that could result in an imperfect 
correlation between the markets, causing a given transaction not 
to achieve its objectives.  The degree of imperfection of 
correlation depends on circumstances such as: variations in 
speculative market demand for futures, futures options and debt 
securities, including technical influences in futures trading 
and futures options and differences between the financial 
instruments and the instruments underlying the standard 
contracts available for trading in such respects as interest 
rate levels, maturities, and creditworthiness of issuers.  A 
decision as to whether, when and how to hedge involves the 
exercise of skill and judgment, and even a well-conceived 
transaction may be unsuccessful to some degree because of market 
behavior or unexpected interest rate trends.

     Futures exchanges may limit the amount of fluctuation 
permitted in certain futures contract prices during a single 
trading day.  The daily limit establishes the maximum amount 
that the price of a futures contract may vary either up or down 
from the previous day's settlement price at the end of the 
current trading session.  Once the daily limit has been reached 
in a futures contract subject to the limit, no more trades may 
be made on that day at a price beyond that limit.  The daily 
limit governs only price movements during a particular trading 
day and therefore does not limit potential losses because the 
limit may work to prevent the liquidation of unfavorable 
positions.  For example, futures prices have occasionally moved 
to the daily limit for several consecutive trading days with 
little or no trading, thereby preventing prompt liquidation of 
positions and subjecting some holders of futures contracts to 
substantial losses.

     There can be no assurance that a liquid market will exist 
at a time when High Yield Portfolio seeks to close out a futures 
or a futures option position.  High Yield Portfolio would be 
exposed to possible loss on the position during the interval of 
inability to close and would continue to be required to meet 
margin requirements until the position is closed.  In addition, 
many of the contracts discussed above are relatively new 
instruments without a significant trading history.  As a result, 
there can be no assurance that an active secondary market will 
develop or continue to exist.

LIMITATIONS ON OPTIONS AND FUTURES

     If other options, futures contracts, or futures options of 
types other than those described herein are traded in the 
future, High Yield Portfolio may also use those investment 
vehicles, provided the Board of Trustees determines that their 
use is consistent with High Yield Portfolio's investment 
objective.

     High Yield Portfolio will not enter into a futures contract 
or purchase an option thereon if, immediately thereafter, the 
initial margin deposits for futures contracts held by High Yield 
Portfolio plus premiums paid by it for open futures option 
positions, less the amount by which any such positions are "in-
the-money," /3/ would exceed 5% of High Yield Portfolio's total 
assets.
- -------------
/3/ A call option is "in-the-money" if the value of the futures 
contract that is the subject of the option exceeds the exercise 
price.  A put option is "in-the-money" if the exercise price 
exceeds the value of the futures contract that is the subject of 
the option.
- -------------

     When purchasing a futures contract or writing a put on a 
futures contract, High Yield Portfolio must maintain with its 
custodian (or broker, if legally permitted) cash or cash 
equivalents (including any margin) equal to the market value of 
such contract.  When writing a call option on a futures 
contract, High Yield Portfolio similarly will maintain with its 
custodian cash or cash equivalents (including any margin) equal 
to the amount by which such option is in-the-money until the 
option expires or is closed out by High Yield Portfolio.

     High Yield Portfolio may not maintain open short positions 
in futures contracts, call options written on futures contracts 
or call options written on indexes if, in the aggregate, the 
market value of all such open positions exceeds the current 
value of the securities in its portfolio, plus or minus 
unrealized gains and losses on the open positions, adjusted for 
the historical relative volatility of the relationship between 
the portfolio and the positions.  For this purpose, to the 
extent High Yield Portfolio has written call options on specific 
securities in its portfolio, the value of those securities will 
be deducted from the current market value of the securities 
portfolio.

     In order to comply with Commodity Futures Trading 
Commission Regulation 4.5 and thereby avoid being deemed a 
"commodity pool operator," High Yield Portfolio will use 
commodity futures or commodity options contracts solely for bona 
fide hedging purposes within the meaning and intent of 
Regulation 1.3(z), or, with respect to positions in commodity 
futures and commodity options contracts that do not come within 
the meaning and intent of 1.3(z), the aggregate initial margin 
and premiums required to establish such positions will not 
exceed 5% of the fair market value of the assets of High Yield 
Portfolio, after taking into account unrealized profits and 
unrealized losses on any such contracts it has entered into [in 
the case of an option that is in-the-money at the time of 
purchase, the in-the-money amount (as defined in Section 
190.01(x) of the Commission Regulations) may be excluded in 
computing such 5%].

     As long as Institutional High Yield Fund continues to sell 
its shares in certain states, High Yield Portfolio's options 
transactions will also be subject to certain non-fundamental 
investment restrictions set forth under Investment Restrictions 
in this Statement of Additional Information.

TAXATION OF OPTIONS AND FUTURES

     If High Yield Portfolio exercises a call or put option that 
it holds, the premium paid for the option is added to the cost 
basis of the security purchased (call) or deducted from the 
proceeds of the security sold (put).  For cash settlement 
options and futures options exercised by High Yield Portfolio, 
the difference between the cash received at exercise and the 
premium paid is a capital gain or loss.

     If a call or put option written by High Yield Portfolio is 
exercised, the premium is included in the proceeds of the sale 
of the underlying security (call) or reduces the cost basis of 
the security purchased (put).  For cash settlement options and 
futures options written by High Yield Portfolio, the difference 
between the cash paid at exercise and the premium received is a 
capital gain or loss.

     Entry into a closing purchase transaction will result in 
capital gain or loss.  If an option written by High Yield 
Portfolio was in-the-money at the time it was written and the 
security covering the option was held for more than the long-
term holding period prior to the writing of the option, any loss 
realized as a result of a closing purchase transaction will be 
long-term.  The holding period of the securities covering an in-
the-money option will not include the period of time the option 
is outstanding.

     A futures contract held until delivery results in capital 
gain or loss equal to the difference between the price at which 
the futures contract was entered into and the settlement price 
on the earlier of delivery notice date or expiration date.  If 
High Yield Portfolio delivers securities under a futures 
contract, High Yield Portfolio also realizes a capital gain or 
loss on those securities.

     For federal income tax purposes, High Yield Portfolio 
generally is required to recognize as income for each taxable 
year its net unrealized gains and losses as of the end of the 
year on options, futures and futures options positions ("year-
end mark-to-market").  Generally, any gain or loss recognized 
with respect to such positions (either by year-end mark-to-
market or by actual closing of the positions) is considered to 
be 60% long-term and 40% short-term, without regard to the 
holding periods of the contracts.  However, in the case of 
positions classified as part of a "mixed straddle," the 
recognition of losses on certain positions (including options, 
futures and futures options positions, the related securities 
and certain successor positions thereto) may be deferred to a 
later taxable year.  Sale of futures contracts or writing of 
call options (or futures call options) or buying put options (or 
futures put options) that are intended to hedge against a change 
in the value of securities held by High Yield Portfolio: (1) 
will affect the holding period of the hedged securities; and (2) 
may cause unrealized gain or loss on such securities to be 
recognized upon entry into the hedge.

     In order for High Yield Portfolio to continue to qualify 
for federal income tax treatment as a regulated investment 
company, at least 90% of its gross income for a taxable year 
must be derived from qualifying income; i.e., dividends, 
interest, income derived from loans of securities, and gains 
from the sale of securities or foreign currencies or other 
income (including but not limited to gains from options, 
futures, and forward contracts).  In addition, gains realized on 
the sale or other disposition of securities held for less than 
three months must be limited to less than 30% of High Yield 
Portfolio's annual gross income.  Any net gain realized from 
futures (or futures options) contracts will be considered gain 
from the sale of securities and therefore be qualifying income 
for purposes of the 90% requirement.  In order to avoid 
realizing excessive gains on securities held less than three 
months, High Yield Portfolio may be required to defer the 
closing out of certain positions beyond the time when it would 
otherwise be advantageous to do so.

     Institutional High Yield Fund distributes to shareholders 
annually any net capital gains that have been recognized for 
federal income tax purposes (including year-end mark-to-market 
gains) on options and futures transactions.  Such distributions 
are combined with distributions of capital gains realized on the 
other investments and shareholders are advised of the nature of 
the payments.

                  INVESTMENT RESTRICTIONS

     Institutional High Yield Fund and High Yield Portfolio 
operate under the following investment restrictions.  
Institutional High Yield Fund and High Yield Portfolio may not:

     (1)  invest in a security if, as a result of such 
investment, more than 25% of its total assets (taken at market 
value at the time of such investment) would be invested in the 
securities of issuers in any particular industry, except that 
this restriction does not apply to U.S. Government Securities,  
and [Institutional High Yield Fund only] except that all or 
substantially all of the assets of the Fund may be invested in 
another registered investment company having the same investment 
objective and substantially similar investment policies as the 
Fund;

     (2)  invest in a security if, with respect to 75% of its 
assets, as a result of such investment, more than 5% of its 
total assets (taken at market value at the time of such 
investment) would be invested in the securities of any one 
issuer, except that this restriction does not apply to U.S. 
Government Securities or repurchase agreements for such 
securities and [Institutional High Yield Fund only] except that 
all or substantially all of the assets of the Fund may be 
invested in another registered investment company having the 
same investment objective and substantially similar investment 
policies as the Fund;

     (3)  invest in a security if, as a result of such 
investment, it would hold more than 10% (taken at the time of 
such investment) of the outstanding voting securities of any one 
issuer, [Institutional High Yield Fund only] except that all or 
substantially all of the assets of the Fund may be invested in 
another registered investment company having the same investment 
objective and substantially similar investment policies as the 
Fund;

     (4)  purchase or sell real estate (although it may purchase 
securities secured by real estate or interests therein, or 
securities issued by companies which invest in real estate, or 
interests therein);

     (5) purchase or sell commodities or commodities contracts 
or oil, gas or mineral programs, except that it may enter into 
(i) futures and options on futures and (ii) forward contracts;

     (6)  purchase securities on margin, except for use of 
short-term credit necessary for clearance of purchases and sales 
of portfolio securities, but it may make margin deposits in 
connection with transactions in options, futures, and options on 
futures;

     (7)  make loans, although it may (a) lend portfolio 
securities and participate in an interfund lending program with 
other Stein Roe Funds and Portfolios provided that no such loan 
may be made if, as a result, the aggregate of such loans would 
exceed 33 1/3% of the value of its total assets (taken at market 
value at the time of such loans); (b) purchase money market 
instruments and enter into repurchase agreements; and (c) 
acquire publicly-distributed or privately-placed debt 
securities;

     (8)  borrow except that it may (a) borrow for non-
leveraging, temporary or emergency purposes, (b) engage in 
reverse repurchase agreements and make other borrowings, 
provided that the combination of (a) and (b) shall not exceed 33 
1/3% of the value of its total assets (including the amount 
borrowed) less liabilities (other than borrowings) or such other 
percentage permitted by law, and (c) enter into futures and 
options transactions; it may borrow from banks, other Stein Roe 
Funds and Portfolios, and other persons to the extent permitted 
by applicable law;

     (9)  act as an underwriter of securities, except insofar as 
it may be deemed to be an "underwriter" for purposes of the 
Securities Act of 1933 on disposition of securities acquired 
subject to legal or contractual restrictions on resale, 
[Institutional High Yield Fund only] except that all or 
substantially all of the assets of the Fund may be invested in 
another registered investment company having the same investment 
objective and substantially similar investment policies as the 
Fund; or

     (10)  issue any senior security except to the extent 
permitted under the Investment Company Act of 1940.

     The above restrictions are fundamental policies and may not 
be changed without the approval of a "majority of the 
outstanding voting securities" of the Fund or High Yield 
Portfolio, as previously defined herein.  The policy on the 
scope of transactions involving lending of portfolio securities 
to broker-dealers and banks (as set forth herein under Portfolio 
Investments and Strategies) is also a fundamental policy.

     Institutional High Yield Fund and High Yield Portfolio are 
also subject to the following restrictions and policies that may 
be changed by the Board of Trustees.  None of the following 
restrictions shall prevent it from investing all or 
substantially all of its assets in another investment company 
having the same investment objective and substantially similar 
investment policies as the Fund.  Unless otherwise indicated, 
Institutional High Yield Fund and High Yield Portfolio may not:

     (A)  invest for the purpose of exercising control or 
management;

     (B)  purchase more than 3% of the stock of another 
investment company or purchase stock of other investment 
companies equal to more than 5% of its total assets (valued at 
time of purchase) in the case of any one other investment 
company and 10% of such assets (valued at time of purchase) in 
the case of all other investment companies in the aggregate; any 
such purchases are to be made in the open market where no profit 
to a sponsor or dealer results from the purchase, other than the 
customary broker's commission, except for securities acquired as 
part of a merger, consolidation or acquisition of assets;/4/
- ------------
/4/Stein Roe Funds have been informed that the staff of the 
Securities and Exchange Commission takes the position that the 
issuers of certain CMOs and certain other collateralized assets 
are investment companies and that subsidiaries of foreign banks 
may be investment companies for purposes of Section 12(d)(1) of 
the Investment Company Act of 1940, which limits the ability of 
one investment company to invest in another investment company.  
Accordingly, High Yield Portfolio intends to operate within the 
applicable limitations under Section 12(d)(1)(A) of that Act.
- ------------
     (C)  mortgage, pledge, hypothecate or in any manner 
transfer, as security for indebtedness, any securities owned or 
held by it, except as may be necessary in connection with (i) 
borrowings permitted in (8) above and (ii) options, futures, and 
options on futures;

     (D)  purchase or retain securities of any issuer if 5% of 
the securities of such issuer are owned by those officers and 
trustees or directors of the Trust or of its investment adviser 
who each own beneficially more than l/2 of 1% of its securities; 

     (E)  purchase portfolio securities from, or sell portfolio 
securities to, any of the officers and directors or trustees of 
the Trust or of its investment adviser;

     (F)  purchase shares of other open-end investment 
companies, except in connection with a merger, consolidation, 
acquisition, or reorganization;

     (G)  invest more than 5% of its net assets (valued at time 
of investment) in warrants, nor more than 2% of its net assets 
in warrants which are not listed on the New York or American 
Stock Exchange;

     (H)  purchase a put or call option if the aggregate 
premiums paid for all put and call options exceed 20% of its net 
assets (less the amount by which any such positions are in-the-
money), excluding put and call options purchased as closing 
transactions;

     (I)  write an option on a security unless the option is 
issued by the Options Clearing Corporation, an exchange, or 
similar entity; 

     (J)   buy or sell an option on a security, a futures 
contract, or an option on a futures contract unless the option, 
the futures contract, or the option on the futures contract is 
offered through the facilities of a national securities 
association or listed on a national exchange or similar entity; 

     (K)  invest in limited partnerships in real estate unless 
they are readily marketable;

     (L)  sell securities short unless (i) it owns or has the 
right to obtain securities equivalent in kind and amount to 
those sold short at no added cost or (ii) the securities sold 
are "when issued" or "when distributed" securities which it 
expects to receive in a recapitalization, reorganization, or 
other exchange for securities it contemporaneously owns or has 
the right to obtain and provided that transactions in options, 
futures, and options on futures are not treated as short sales;

     (M)  invest more than 5% of its total assets (taken at 
market value at the time of a particular investment) in 
securities of issuers (other than issuers of federal agency 
obligations or securities issued or guaranteed by any foreign

predecessors or unconditional guarantors, have been in 
continuous operation for less than three years ("unseasoned 
issuers");

     (N)  invest more than 15% of its total assets (taken at

restricted securities, other than securities eligible for resale 
pursuant to Rule 144A under the Securities Act of 1933;

     (O)  invest more than 15% of its total assets (taken at 
market value at the time of a particular investment) in 
restricted securities and securities of unseasoned issuers; or

     (P)  invest more than 10% of its net assets (taken at 
market value at the time of a particular investment) in illiquid 
securities /5/, including repurchase agreements maturing in more 
than seven days.
- -------------
/5/ In the judgment of the Adviser, Private Placement Notes, 
which are issued pursuant to Section 4(2) of the Securities Act 
of 1933, generally are readily marketable even though they are 
subject to certain legal restrictions on resale.  As such, they 
are not treated as being subject to the limitation on illiquid 
securities.
- -------------

           ADDITIONAL INVESTMENT CONSIDERATIONS

     The Adviser seeks to provide superior long-term investment 
results through a disciplined, research-intensive approach to 
investment selection and prudent risk management.  In working to 
build wealth for generations, it has been guided by three 
primary objectives which it believes are the foundation of a 
successful investment program.  These objectives are 
preservation of capital, limited volatility through managed 
risk, and consistent above-average returns, as appropriate for 
the particular client or managed account.

     Because every investor's needs are different, Stein Roe 
mutual funds are designed to accommodate different investment 
objectives, risk tolerance levels, and time horizons.  In 
selecting a mutual fund, investors should ask the following 
questions:

What are my investment goals?
It is important to a choose a fund that has investment 
objectives compatible with your investment goals.

What is my investment time frame?
If you have a short investment time frame (e.g., less than three 
years), a mutual fund that seeks to provide a stable share 
price, such as a money market fund, or one that seeks capital 
preservation as one of its objectives may be appropriate.  If 
you have a longer investment time frame, you may seek to 
maximize your investment returns by investing in a mutual fund 
that offers greater yield or appreciation potential in exchange 
for greater investment risk.

What is my tolerance for risk?
All investments, including those in mutual funds, have risks 
which will vary depending on investment objective and security 
type.  However, mutual funds seek to reduce risk through 
professional investment management and portfolio 
diversification.

     In general, equity mutual funds emphasize long-term capital 
appreciation and tend to have more volatile net asset values 
than bond or money market mutual funds.  Although there is no 
guarantee that they will be able to maintain a stable net asset 
value of $1.00 per share, money market funds emphasize safety of 
principal and liquidity, but tend to offer lower income 
potential than bond funds.  Bond funds tend to offer higher 
income potential than money market funds but tend to have 
greater risk of principal and yield volatility.  

     In addition, the Adviser believes that investment in a high 
yield fund provides an opportunity to diversify an investment 
portfolio because the economic factors that affect the 
performance of high-yield, high-risk debt securities differ from 
those that affect the performance of high-quality debt 
securities or equity securities.

                  PURCHASES AND REDEMPTIONS

     Purchases and redemptions are discussed in the Prospectus 
under the headings How to Purchase Shares, How to Redeem Shares, 
and Net Asset Value, and that information is incorporated herein 
by reference.  The Prospectus discloses that shares may be 
purchased (or redeemed) through investment dealers, banks, or 
other intermediaries.  It is the responsibility of any such 
intermediary to establish procedures insuring the prompt 
transmission to Institutional Trust of any such purchase order.  
The state of Texas has asked that mutual funds disclose in their 
Statement of Additional Information, as a reminder to any such 
intermediary, that it must be registered as a dealer in Texas.

     Through an account with an Intermediary, a shareholder may 
be able to exchange shares of Institutional High Yield Fund for 
shares of another Stein Roe Fund.  Each Intermediary will 
establish its own exchange policy and procedures for its 
accounts.  Shares are exchanged at the next price calculated on 
a day the NYSE is open, after an exchange order is received and 
accepted by an Intermediary.

- - Shares can be exchanged only between accounts registered in 
  the same name, address, and taxpayer ID number of the 
  Intermediary.
- - An exchange can be made only into a Stein Roe Fund whose 
  shares are eligible for sale in the state where the Intermediary 
  is located.
- - An exchange may have tax consequences.
- - Institutional High Yield Fund may refuse any exchange orders 
  from any Intermediary if for any reason they are not deemed to 
  be in the best interests of the Fund and its shareholders.
- - Institutional High Yield Fund may impose other restrictions on 
  the exchange privilege, or modify or terminate the privilege, 
  but will try to give each Intermediary advance notice whenever 
  it can reasonably do so.

     Institutional High Yield Fund's net asset value is 
determined on days on which the New York Stock Exchange (the 
"NYSE") is open for trading.  The NYSE is regularly closed on 
Saturdays and Sundays and on New Year's Day, the third Monday in 
February, Good Friday, the last Monday in May, Independence Day, 
Labor Day, Thanksgiving, and Christmas.  If one of these 
holidays falls on a Saturday or Sunday, the NYSE will be closed 
on the preceding Friday or the following Monday, respectively.  
Net asset value will not be determined on days when the NYSE is 
closed unless, in the judgment of the Board of Trustees, net 
asset value of Institutional High Yield Fund should be 
determined on any such day, in which case the determination will 
be made at 3:00 p.m., central time.

     Institutional Trust reserves the right to suspend or 
postpone redemptions of shares of its series during any period 
when: (a) trading on the NYSE is restricted, as determined by 
the Securities and Exchange Commission, or the NYSE is closed 
for other than customary weekend and holiday closings; (b) the 
Securities and Exchange Commission has by order permitted such 
suspension; or (c) an emergency, as determined by the Securities 
and Exchange Commission, exists, making disposal of portfolio 
securities or valuation of net assets of a series not reasonably 
practicable.

     Institutional Trust intends to pay all redemptions in cash 
and is obligated to redeem shares of its series solely in cash 
up to the lesser of $250,000 or one percent of the net assets of 
Institutional High Yield Fund during any 90-day period for any 
one shareholder.  However, redemptions in excess of such limit 
may be paid wholly or partly by a distribution in kind of 
securities.  If redemptions were made in kind, the redeeming 
shareholders might incur transaction costs in selling the 
securities received in the redemptions.

     Due to the relatively high cost of maintaining smaller 
accounts, Institutional Trust reserves the right to redeem 
shares in any account for their then-current value (which will 
be promptly paid to the investor) if at any time the shares in 
the account do not have a value of at least $100,000.  An 
investor will be notified that the value of his account is less 
than the minimum and allowed at least 30 days to bring the value 
of the account up to at least $100,000 before the redemption is 
processed.  The Agreement and Declaration of Trust also 
authorizes Institutional Trust to redeem shares under certain 
other circumstances as may be specified by the Board of 
Trustees.

compensation for their services to Institutional Trust, trustees 
who are not "interested persons" of Institutional Trust or the

among the series of Institutional Trust) plus an attendance fee 
from each series for each meeting of the Board or standing 
committee thereof attended at which business for the series is 
conducted.  The attendance fees (other than for a Nominating 
Committee meeting) are based on each series' net assets as of 
the preceding December 31.  For a series with net assets of less 
than $50 million, the fee is $50 per meeting; with $51 to $250 
million, the fee is $200 per meeting; with $251 million to $500 
million, $350; with $501 million to $750 million, $500; with 
$751 million to $1 billion, $650; and with over $1 billion in 
net assets, $800.  For Institutional High Yield Fund and any 
other series of Institutional Trust participating in the master 
fund/feeder fund structure, the trustees' attendance fee is paid 
solely by the master portfolio.  Each non-interested trustee 
also receives $500 from Institutional Trust for attending each 
meeting of the Nominating Committee.  Institutional Trust has no

registration and custodian fees and expenses incidental to its 
organization.

     Institutional High Yield Fund's administrative agreement 
provides that the Adviser shall reimburse the Fund to the extent 
that its total annual expenses (including fees paid to the 
Adviser, but excluding taxes, interest, brokers' commissions and 
other normal charges incident to the purchase and sale of 
portfolio securities, and expenses of litigation to the extent 
permitted under applicable state law) exceed the applicable 
limits prescribed by any state in which shares of Institutional 
High Yield Fund are being offered for sale to the public; 
however, such reimbursement for any fiscal year will not exceed 
the amount of the fees paid by Institutional High Yield Fund 
under that agreement for such year.  In addition, in the 
interest of further limiting Institutional High Yield Fund's 
expenses, the Adviser may voluntarily waive its management fee 
and/or absorb certain its expenses, as described in the 
Prospectus under Fee Table.  Any such reimbursements will 
enhance the yield of the Fund.

     High Yield Portfolio's management agreement provides that 
neither the Adviser nor any of its directors, officers, 
stockholders (or partners of stockholders), agents, or employees 
shall have any liability to Base Trust or any shareholder of 
High Yield Portfolio for any error of judgment, mistake of law 
or any loss arising out of any investment, or for any other act 
or omission in the performance by the Adviser of its duties 
under the agreement, except for liability resulting from willful 
misfeasance, bad faith or gross negligence on the Adviser's part 
in the performance of its duties or from reckless disregard by 
the Adviser of the Adviser's obligations and duties under that 
agreement.

     Any expenses that are attributable solely to the 
organization, operation, or business of Institutional High Yield 
Fund shall be paid solely out of that Fund's assets.  Any 
expenses incurred by Institutional Trust that are not solely 
attributable to a particular Fund are apportioned in such manner 
as the Adviser determines is fair and appropriate, unless 
otherwise specified by the Board of Trustees.

                        DISTRIBUTOR

     Shares of Institutional High Yield Fund are distributed by 
Liberty Securities Corporation ("LSC"), under a Distribution 
Agreement as described under Management in the Prospectus, which 
is incorporated herein by reference.  The Distribution Agreement 
continues in effect from year to year, provided such continuance 
is approved annually (i) by a majority of the trustees or by a 
majority of the outstanding voting securities of Institutional 
Trust, and (ii) by a majority of the trustees who are not 
parties to the Agreement or interested persons of any such 
party.  Institutional Trust has agreed to pay all expenses in 
connection with registration of its shares with the Securities 
and Exchange Commission and auditing and filing fees in 
connection with registration of its shares under the various 
state blue sky laws and assumes the cost of preparation of 
prospectuses and other expenses. 

     As agent, LSC offers shares of Institutional High Yield 
Fund to investors in states where the shares are qualified for 
sale, at net asset value, without sales commissions or other 
sales load to the investor.  No sales commission or "12b-1" 
payment is paid by Institutional High Yield Fund.  LSC offers 
Institutional High Yield Fund's shares only on a best-efforts 
basis.

                     TRANSFER AGENT

     SSI performs certain transfer agency services for 
Institutional Trust, as described under Management in the 
Prospectus.  For performing these services, SSI receives from 
Institutional High Yield Fund a fee based on an annual rate of 
 .05 of 1% of average daily net assets of Institutional High 
Yield Fund.  The Board of Trustees believes the charges by SSI 
are comparable to those of other companies performing similar 
services.  (See Investment Advisory Services.)

                         CUSTODIAN

     State Street Bank and Trust Company (the "Bank"), 225 
Franklin Street, Boston, Massachusetts 02101, is the custodian 
for Institutional Trust and Base Trust.  It is responsible for 
holding all securities and cash, receiving and paying for 
securities purchased, delivering against payment securities 
sold, receiving and collecting income from investments, making 
all payments covering expenses, and performing other 
administrative duties, all as directed by authorized persons.  
The custodian does not exercise any supervisory function in such 
matters as purchase and sale of portfolio securities, payment of 
dividends, or payment of expenses.

     Portfolio securities purchased in the U.S. are maintained 
in the custody of the Bank or of other domestic banks or 
depositories.  Portfolio securities purchased outside of the 
U.S. are maintained in the custody of foreign banks and trust 
companies that are members of the Bank's Global Custody Network, 
and foreign depositories ("foreign sub-custodians").  Each of 
the domestic and foreign custodial institutions holding 
portfolio securities has been approved by the Board of Trustees 
in accordance with regulations under the Investment Company Act 
of 1940.

     Each Board of Trustees reviews, at least annually, whether 
it is in the best interest of Institutional High Yield Fund, 
High Yield Portfolio, and their shareholders to maintain assets 
in each custodial institution.  However, with respect to foreign 
sub-custodians, there can be no assurance that it, and the value 
of its shares, will not be adversely affected by acts of foreign 
governments, financial or operational difficulties of the 
foreign sub-custodians, difficulties and costs of obtaining 
jurisdiction over, or enforcing judgments against, the foreign 
sub-custodians, or application of foreign law to the foreign 
sub-custodial arrangements.  Accordingly, an investor should 
recognize that the non-investment risks involved in holding 
assets abroad are greater than those associated with investing 
in the United States.

     Institutional High Yield Fund and High Yield Portfolio may 
invest in obligations of the custodian and may purchase or sell 
securities from or to the custodian.

                   INDEPENDENT AUDITORS

     The independent auditors for Institutional Trust and High 
Yield Portfolio are Ernst & Young LLP, 233 South Wacker Drive, 
Chicago, Illinois 60606.  The independent auditors audit and 
report on the annual financial statements, review certain 
regulatory reports and the federal income tax returns, and 
perform other professional accounting, auditing, tax and 
advisory services when engaged to do so by the applicable Trust.

                  PORTFOLIO TRANSACTIONS

     The Adviser places the orders for the purchase and sale of 
portfolio securities and options and futures contracts for High 
Yield Portfolio.  Purchases and sales of portfolio securities 
are ordinarily transacted with the issuer or with a primary 
market maker acting as principal or agent for the securities on 
a net basis, with no brokerage commission being paid by High 
Yield Portfolio.  Transactions placed through dealers reflect 
the spread between the bid and asked prices.  Occasionally, High 
Yield Portfolio may make purchases of underwritten issues at 
prices that include underwriting discounts or selling 
concessions.

     The Adviser's overriding objective in effecting portfolio 
transactions is to seek to obtain the best combination of price 
and execution.  The best net price, giving effect to transaction 
charges, if any, and other costs, normally is an important 
factor in this decision, but a number of other judgmental 
factors may also enter into the decision.  These include: the 
Adviser's knowledge of current transaction costs; the nature of 
the security being traded; the size of the transaction; the 
desired timing of the trade; the activity existing and expected 
in the market for the particular security; confidentiality; the 
execution, clearance and settlement capabilities of the broker 
or dealer selected and others that are considered; the Adviser's 
knowledge of the financial stability of the broker or dealer 
selected and such other brokers or dealers; and the Adviser's 
knowledge of actual or apparent operational problems of any 
broker or dealer.  Recognizing the value of these factors, High 
Yield Portfolio may incur a transaction charge in excess of that 
which another broker or dealer may have charged for effecting 
the same transaction.  Evaluations of the reasonableness of the 
costs of portfolio transactions, based on the foregoing factors, 
are made on an ongoing basis by the Adviser's staff and reports 
are made annually to the Board of Trustees.

     With respect to issues of securities involving brokerage 
commissions, when more than one broker or dealer is believed to 
be capable of providing the best combination of price and 
execution with respect to a particular portfolio transaction for 
High Yield Portfolio, the Adviser often selects a broker or 
dealer that has furnished it with research products or services 
such as research reports, subscriptions to financial 
publications and research compilations, compilations of 
securities prices, earnings, dividends and similar data, and 
computer databases, quotation equipment and services, research-
oriented computer software and services, and services of 
economic and other consultants.  Selection of brokers or dealers 
is not made pursuant to an agreement or understanding with any 
of the brokers or dealers; however, the Adviser uses an internal 
allocation procedure to identify those brokers or dealers who 
provide it with research products or services and the amount of 
research products or services they provide, and endeavors to 
direct sufficient commissions generated by its clients' accounts 
in the aggregate, including High Yield Portfolio, to such 
brokers or dealers to ensure the continued receipt of research 
products or services the Adviser feels are useful.  In certain 
instances, the Adviser receives from brokers and dealers 
products or services which are used both as investment research 
and for administrative, marketing, or other non-research 
purposes.  In such instances, the Adviser makes a good faith 
effort to determine the relative proportions of such products or 
services which may be considered as investment research.  The 
portion of the costs of such products or services attributable 
to research usage may be defrayed by the Adviser (without prior 
agreement or understanding, as noted above) through brokerage 
commissions generated by transactions of clients (including High 
Yield Portfolio), while the portion of the costs attributable to 
non-research usage of such products or services is paid by the 
Adviser in cash.  No person acting on behalf of High Yield 
Portfolio is authorized, in recognition of the value of research 
products or services, to pay a price in excess of that which 
another broker or dealer might have charged for effecting the 
same transaction.  Research products or services furnished by 
brokers and dealers through whom transactions are effected may 
be used in servicing any or all of the clients of the Adviser 
and not all such research products or services are used in 
connection with the management of High Yield Portfolio.

     The Board has reviewed the legal developments pertaining to 
and the practicability of attempting to recapture underwriting 
discounts or selling concessions when portfolio securities are 
purchased in underwritten offerings.  The Board has been advised 
by counsel that recapture by a mutual fund currently is not 
permitted under the Rules of Fair Practice of the National 
Association of Securities Dealers ("NASD").

             ADDITIONAL INCOME TAX CONSIDERATIONS

     Institutional High Yield Fund and High Yield Portfolio 
intend to comply with the special provisions of the Internal 
Revenue Code that relieve it of federal income tax to the extent 
of its net investment income and capital gains currently 
distributed to shareholders.

     Because capital gain distributions reduce net asset value, 
if a shareholder purchases shares shortly before a record date, 
he will, in effect, receive a return of a portion of his 
investment in such distribution.  The distribution would 
nonetheless be taxable to him, even if the net asset value of 
shares were reduced below his cost.  However, for federal income 
tax purposes the shareholder's original cost would continue as 
his tax basis.

     Institutional High Yield Fund expects that none of its 
dividends will qualify for the deduction for dividends received 
by corporate shareholders.

               INVESTMENT PERFORMANCE

     Institutional High Yield Fund may quote yield figures from 
time to time.  "Yield" is computed by dividing the net 
investment income per share earned during a 30-day period (using 
the average number of shares entitled to receive dividends) by 
the net asset value per share on the last day of the period.  
The Yield formula provides for semiannual compounding which 
assumes that net investment income is earned and reinvested at a 
constant rate and annualized at the end of a six-month period.  
For a given period, an "Average Annual Total Return" may be 
computed by finding the average annual compounded rate that 
would equate a hypothetical initial amount invested of $1,000 to 
the ending redeemable value.

                                                         6 
The Yield formula is as follows:  YIELD = 2[((a-b/cd) +1)  -1].

 Where:  a  =  dividends and interest earned during the period
            .  (For this purpose, the Fund will recalculate the 
               yield to maturity based on market value of each 
               portfolio security on each business day on which 
               net asset value is calculated.)
         b  =  expenses accrued for the period (net of 
               reimbursements).
         c  =  the average daily number of shares outstanding 
               during the period that were entitled to receive 
               dividends.
         d  =  the ending net asset value of Institutional High 
               Yield Fund for the period.
                  _____________________

      Institutional High Yield Fund may quote total return 
figures from time to time.  A "Total Return" on a per share 
basis is the amount of dividends received per share plus or 
minus the change in the net asset value per share for a period.  
A "Total Return Percentage" may be calculated by dividing the 
value of a share at the end of a period (including reinvestment 
of distributions) by the value of the share at the beginning of 
the period and subtracting one.
                                                                n
Average Annual Total Return is computed as follows: ERV = P(1+T)

 Where:   P  =  a hypothetical initial payment of $1,000
          T  =  average annual total return
          n  =  number of years
        ERV  =  ending redeemable value of a hypothetical $1,000 
                payment made at the beginning of the period at the 
                end of the period (or fractional portion thereof).

     Investment performance figures assume reinvestment of all 
dividends and distributions and do not take into account any 
federal, state, or local income taxes which shareholders must 
pay on a current basis.  They are not necessarily indicative of 
future results.  The performance of Institutional High Yield 
Fund is a result of conditions in the securities markets, 
portfolio management, and operating expenses.  Although 
investment performance information is useful in reviewing 
Institutional High Yield Fund's performance and in providing 
some basis for comparison with other investment alternatives, it 
should not be used for comparison with other investments using 
different reinvestment assumptions or time periods.

     In advertising and sales literature, Institutional High 
Yield Fund may compare its yield and performance with that of 
other mutual funds, indexes or averages of other mutual funds, 
indexes of related financial assets or data, and other competing 
investment and deposit products available from or through other 
financial institutions.  The composition of these indexes or 
averages differs from that of Institutional High Yield.  
Comparison of Institutional High Yield Fund to an alternative 
investment should be made with consideration of differences in 
features and expected performance.

     All of the indexes and averages noted below will be 
obtained from the indicated sources or reporting services, which 
Institutional Trust believes to be generally accurate.  
Institutional High Yield Fund may also note its mention in 
newspapers, magazines, or other media from time to time.  
However, Institutional Trust assumes no responsibility for the 
accuracy of such data.  Newspapers and magazines that might 
mention Institutional High Yield Fund include, but are not 
limited to, the following:

     Institutional High Yield Fund may compare its performance 
to the Consumer Price Index (All Urban), a widely-recognized 
measure of inflation.

     The performance of Institutional High Yield Fund may be 
compared to the following as indicated below:

          CS First Boston High Yield Index
          ICD High Yield Index
          Lehman High Yield Bond Index
          Lehman High Yield Corporate Bond Index
          Merrill Lynch High-Yield Master Index
          Morningstar Corporate Bond (General) Average
          Salomon Brothers Extended High Yield Market Index
          Salomon Brothers High Yield Market Index

     The Lipper and Morningstar averages are unweighted averages 
of total return performance of mutual funds as classified, 
calculated, and published by these independent services that 
monitor the performance of mutual funds.  Institutional High 
Yield Fund may also use comparative performance as computed in a 
ranking by these services or category averages and rankings 
provided by another independent service.  Should these services 
reclassify Institutional High Yield Fund to a different category 
or develop (and place it into) a new category, it may compare 
its performance or rank against other funds in the newly-
assigned category (or the average of such category) as published 
by the service.

     In advertising and sales literature, Institutional High 
Yield Fund may also cite its rating, recognition, or other 
mention by Morningstar or any other entity.  Morningstar's 
rating system is based on risk-adjusted total return performance 
and is expressed in a star-rating format.  The risk-adjusted 
number is computed by subtracting Institutional High Yield 
Fund's risk score (which is a function of the Fund's monthly 
returns less the 3-month T-bill return) from its load-adjusted 
total return score.  This numerical score is then translated 
into rating categories, with the top 10% labeled five star, the 
next 22.5% labeled four star, the next 35% labeled three star, 
the next 22.5% labeled two star, and the bottom 10% one star.  A 
high rating reflects either above-average returns or below-
average risk, or both.

     Of course, past performance is not indicative of future 
results.
                      ____________________

     To illustrate the historical returns on various types of 
financial assets, Institutional High Yield Fund may use 
historical data provided by Ibbotson Associates, Inc. 
("Ibbotson"), a Chicago-based investment firm.  Ibbotson 
constructs (or obtains) very long-term (since 1926) total return 
data (including, for example, total return indexes, total return 
percentages, average annual total returns and standard 
deviations of such returns) for the following asset types:

            Common stocks
            Small company stocks
            Long-term corporate bonds
            Long-term government bonds

     Institutional High Yield Fund may also use hypothetical 
returns to be used as an example in a mix of asset allocation 
strategies.  One such example is reflected in the chart below, 
which shows the effect of tax deferral on a hypothetical 
investment.  This chart assumes that an investor invested $2,000 
a year on January 1, for any specified period, in both a Tax-
Deferred Investment and a Taxable Investment, that both 
investments earn either 6%, 8% or 10% compounded annually, and 
that the investor withdrew the entire amount at the end of the 
period.  (A tax rate of 39.6% is applied annually to the Taxable 
Investment and on the withdrawal of earnings on the Tax-Deferred 
Investment.)

     Average Life Calculations.  From time to time, 
Institutional High Yield Fund may quote an average life figure 
for its portfolio.  Average life is the weighted average period 
over which the Adviser expects the principal to be paid, and 
differs from stated maturity in that it estimates the effect of 
expected principal prepayments and call provisions.  With 
respect to GNMA securities and other mortgage-backed securities, 
average life is likely to be substantially less than the stated 
maturity of the mortgages in the underlying pools.  With respect 
to obligations with call provisions, average life is typically 
the next call date on which the obligation reasonably may be 
expected to be called.  Securities without prepayment or call 
provisions generally have an average life equal to their stated 
maturity.

     Dollar Cost Averaging.  Dollar cost averaging is an 
investment strategy that requires investing a fixed amount of 
money in Fund shares at set intervals.  This allows you to 
purchase more shares when prices are low and fewer shares when 
prices are high.  Over time, this tends to lower your average 
cost per share.

     Like any investment strategy, dollar cost averaging can't 
guarantee a profit or protect against losses in a steadily 
declining market.  Dollar cost averaging involves uninterrupted 
investing regardless of share price and therefore may not be 
appropriate for every investor.

              REPORT OF INDEPENDENT AUDITORS


The Board of Trustees
Stein Roe Institutional Trust


We have audited the accompanying statement of net assets of 
Stein Roe Institutional High Yield Fund, a series of Stein 
Roe Institutional Trust, as of December 12, 1996.  This 
statement of net assets is the responsibility of the Fund's 
management. Our responsibility is to express an opinion on 
this statement of net assets based on our audit.

We conducted our audit in accordance with generally accepted 
auditing standards.  Those standards require that we plan and 
perform the audit to obtain reasonable assurance about 
whether the statement of net assets is free of material 
misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the 
statement of net assets.  An audit also includes assessing 
the accounting principles used and significant estimates made 
by management, as well as evaluating the overall statement of 
net assets presentation.  We believe that our audit of the 
statement of net assets provides a reasonable basis for our 
opinion.

In our opinion, the statement of net assets referred to above 
presents fairly, in all material respects, the financial 
position of Stein Roe Institutional High Yield Fund at
