STEIN ROE INSTITUTIONAL CLIENT HIGH YIELD FUND
Institutional Client High Yield Fund seeks total return by 
investing for a high level of current income and capital growth.  
Institutional Client High Yield Fund seeks to achieve its 
objective by investing all of its net investable assets in SR&F 
High Yield Portfolio, a portfolio of SR&F Base Trust that has the 
same investment objective and substantially the same investment 
policies as Institutional Client High Yield Fund.  High Yield 
Portfolio invests primarily in high-yield, high-risk medium- and 
lower-quality debt securities.  LOWER-QUALITY SECURITIES, COMMONLY 
KNOWN AS "JUNK BONDS," ARE SUBJECT TO A GREATER RISK WITH REGARD 
TO PAYMENT OF INTEREST AND RETURN OF PRINCIPAL THAN HIGHER-RATED 
BONDS.  INVESTORS SHOULD CAREFULLY CONSIDER THE RISKS ASSOCIATED 
WITH JUNK BONDS BEFORE INVESTING.  (SEE INVESTMENT POLICIES, RISKS 
AND INVESTMENT CONSIDERATIONS, SPECIAL CONSIDERATIONS REGARDING 
MASTER FUND/FEEDER FUND STRUCTURE, AND APPENDIX.)

Institutional Client High Yield Fund is a "no-load" fund.  There 
are no sales or redemption charges, and the Fund has no 12b-1 
plan.  Institutional Client High Yield Fund is a series of the 
Stein Roe Trust and High Yield Portfolio is a series of SR&F Base 
Trust.  Each Trust is a diversified open-end management investment 
company.

Shares of Institutional Client High Yield Fund are intended 
primarily for investors who are (or through purchase of Fund 
shares become) clients of the Institutional Asset Management 
Division of Stein Roe & Farnham Incorporated.

                           SUMMARY

Stein Roe Institutional Client High Yield Fund ("Institutional 
Client High Yield Fund") is a series of Stein Roe Trust, an open-
end diversified management investment company organized as a 
Massachusetts business trust.  Institutional Client High Yield 
Fund offers 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 Client High 
Yield Fund are not qualified for sale.

INVESTMENT OBJECTIVES AND POLICIES.  Institutional Client 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 Client 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 Client High Yield Fund and High Yield Portfolio will 
achieve their common investment objective.

INVESTMENT RISKS.  The risks inherent in Institutional Client 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 Client 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 Client High Yield Fund can be assured.  
Institutional Client 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.  For 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 Client High Yield Fund unless you elect to have 
distributions paid 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 
Client 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
                   ------     -------
                    $5          $16

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 Client High Yield Fund.  
Because Institutional Client 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 Client High Yield Fund and the 
Fund's pro rata share of the fees and expenses payable by High 
Yield Portfolio.  The Adviser has agreed to voluntarily waive such 
fees to the extent the ordinary operating expenses of 
Institutional Client High Yield Fund exceed 0.50% of its annual 
average net assets.  This commitment will be reviewed by the 
Adviser on January 31, 2000, at which time the commitment could be 
continued or terminated.  In addition, the commitment is 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, Other Expenses and 
Total Fund Operating Expenses would be 0.65%, 0.35% and 1.00%, 
respectively.  Any such fee waiver will lower Institutional Client 
High Yield Fund's overall expense ratio and increase its overall 
return to investors.  (Also see Management--Fees and Expenses.)

Institutional Client 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 Client High Yield Fund and High Yield 
Portfolio.  Fees and expenses are described under Management.  
Institutional Client High Yield Fund bears its proportionate share 
of Portfolio expenses.  The Trustees of Stein Roe Trust have 
considered whether the annual operating expenses of Institutional 
Client High Yield Fund, including its proportionate share of the 
expenses of High Yield Portfolio, would be more or less than if 
Institutional Client High Yield Fund invested directly in the 
securities held by High Yield Portfolio, and concluded that 
Institutional Client 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 Client 
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 CLIENT HIGH YIELD FUND ("Institutional 
Client High Yield Fund") is a no-load, diversified "mutual fund."  
Institutional Client High Yield Fund does not impose commissions 
or charges when shares are purchased or redeemed.  Institutional 
Client High Yield Fund is a series of Stein Roe 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 Client High Yield Fund 
and High Yield Portfolio. 

Rather than invest in securities directly, Institutional Client 
High Yield Fund seeks to achieve its investment objective by using 
the "master fund/feeder fund" structure.  Under that structure, 
Institutional Client High Yield Fund and other investment 
companies with the same investment objective invest their assets 
in another investment company having the same investment objective 
and substantially the same investment policies as Institutional 
Client High Yield Fund.  The purpose of such an arrangement is to 
achieve greater operational efficiencies and reduce costs.  
Institutional Client High Yield Fund invests all of its net 
investable assets in 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 Client 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 Client 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 Client 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 Client 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 Client 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 Client 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 and Portfolios.  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 Client 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 Client 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 Client 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 Client 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, different 
accounting, auditing and financial reporting standards, different 
settlement practices, 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 Client 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 Client 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

Shares of Institutional Client High Yield Fund are intended 
primarily for investors who are (or through purchase of Fund 
shares become) clients of Stein Roe's Institutional Asset 
Management Division.  Shares may also be available to other 
investors if, in the judgment of the Adviser, the sale of shares 
to such investors would not adversely affect the Fund or its 
shareholders.  The initial purchase minimum is $1,000,000 and the 
minimum subsequent investment is $100,000.  For more information 
on how to purchase Fund shares, please call  Stein Roe Retirement 
Services at 800-322-1130.  Stein Roe Trust reserves the right to 
waive or lower its investment minimums for any reason.

CONDITIONS OF PURCHASE.  Each purchase order for Institutional 
Client High Yield Fund must be accepted by an authorized officer 
of Stein Roe Trust or its authorized agent and is not binding 
until accepted and entered on the books of Institutional Client 
High Yield Fund.  Once your purchase order has been accepted, you 
may not cancel or revoke it;  you may, however, redeem the shares.  
Stein Roe Trust reserves the right not to accept any purchase 
order that it determines not to be in the best interests of Stein 
Roe Trust or of Institutional Client High Yield Fund's 
shareholders.  

PURCHASE PRICE AND EFFECTIVE DATE.  Each purchase of Institutional 
Client High Yield Fund's shares is made at its net asset value 
(see Net Asset Value) next determined after receipt of an order in 
good form, including receipt of payment by Institutional Client 
High Yield Fund.

                    HOW TO REDEEM SHARES

Shares of Institutional Client High Yield Fund may be redeemed any 
day the New York Stock Exchange ("NYSE") is open at the net asset 
value next calculated after a redemption order is received and 
accepted by Stein Roe Trust.  

Redemption instructions may not be cancelled or revoked once they 
have been received and accepted by Stein Roe Trust.  Stein Roe 
Trust cannot accept a redemption request that specifies a 
particular date or price for redemption or any special conditions.  
Because the redemption price you receive depends upon 
Institutional Client High Yield Fund's net asset value per share 
at the time of redemption, it may be more or less than the price 
you originally paid for the shares and may result in a realized 
capital gain or loss.  Stein Roe Trust will generally mail payment 
for shares redeemed within seven days after proper instructions 
are received. 

Stein Roe Trust reserves the right to redeem shares in any account 
and send the proceeds to the owner if the shares in the account do 
not have a value of at least $1,000,000.  A shareholder would be 
notified that his account is below the minimum and would be 
allowed 30 days to increase the account before the redemption is 
processed.

                      NET ASSET VALUE

The purchase and redemption price of Institutional Client High 
Yield Fund's shares is its net asset value per share.  
Institutional Client 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 Client 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 Client 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 
Client 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 Client 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 will be 
reinvested in additional shares unless you elect to have 
distributions paid in cash.  Reinvestment normally occurs on the 
payable date.  Stein Roe Trust reserves the right to reinvest the 
proceeds and future distributions in additional shares of 
Institutional Client High Yield Fund if checks mailed to you for 
distributions are returned as undeliverable or are not presented 
for payment within six months.

INCOME TAXES.  Your distributions will be taxable to you, 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.

You 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.

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

For federal income tax purposes, Institutional Client High Yield 
Fund is treated as a separate taxable entity distinct from any 
other series of the Stein Roe 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 Client 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 Client 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 Client High Yield Fund's yield or 
total return with those of alternative investments should consider 
differences between Institutional Client 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 800-322-1130.

                          MANAGEMENT

TRUSTEES AND INVESTMENT ADVISER.  The Board of Trustees of the 
Stein Roe Trust has overall management responsibility for Stein 
Roe Trust and Institutional Client 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 Stein Roe 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 Client High Yield Fund and High Yield 
Portfolio.

The Adviser, Stein Roe & Farnham Incorporated, One South Wacker 
Drive, Chicago, Illinois 60606, is responsible for managing the 
investment portfolio of High Yield Portfolio and the business

direction of the respective Board.  The Adviser is registered as 
an investment adviser under the Investment Advisers Act of 1940.  
The Adviser was organized in 1986 to succeed to the business of 
Stein Roe & Farnham, a partnership that had advised and managed

of Liberty Financial Companies, Inc. ("Liberty Financial"), which 
in turn is a majority owned indirect subsidiary of Liberty Mutual 
Insurance Company.

January 1994.  As a senior research analyst for the Adviser's 
fixed income department from 1994 to 1997, Mr. Lockman has 
broad expertise in the fixed income markets, with specialties 
in the high yield sector and the aerospace, broadcasting, 
entertainment, insurance, mining/metals, paper/forest 
products, printing, publishing and real estate industries.

FEES AND EXPENSES.  The Adviser is entitled to receive a monthly 
administrative fee from Institutional Client High Yield Fund, 
computed and accrued daily, at an annual rate of .150% of the 
first $500 million of average net assets and .125% thereafter; and 
a monthly management fee from High Yield Portfolio, computed and 
accrued daily, at an annual rate of .500% of the first $500 
million of average net assets and .475% thereafter.  However, as 
noted above under Fee Table, the Adviser may voluntarily waive a 
portion of its fees.

The Adviser provides office space and executive and other 
personnel to Stein Roe Trust and Base Trust and bears any sales or 
promotional expenses.  All expenses of Institutional Client 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 Client High Yield Fund.

Under a separate agreement with each Trust, the Adviser provides 
certain accounting and bookkeeping services to Institutional 
Client 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.  In doing so, the Adviser seeks to obtain the best 
combination of price and execution, which involves a number of 
judgmental factors.

TRANSFER AGENT.  SteinRoe Services Inc. ("SSI"), One South Wacker 
Drive, Chicago, Illinois 60606, a wholly owned subsidiary of 
Liberty Financial, is the agent of Stein Roe Trust for the 
transfer of shares, disbursement of dividends, and maintenance of 
shareholder accounting records.

DISTRIBUTOR.  The shares of Institutional Client High Yield Fund 
are offered for sale through Liberty Securities Corporation 
("Distributor") without any sales commissions or charges to 
Institutional Client High Yield Fund or to its shareholders.  The 
Distributor is a wholly owned indirect subsidiary of Liberty 
Financial.  The business address of the Distributor is 600 
Atlantic Avenue, Boston, Massachusetts 02210; however, all Fund 
correspondence (including purchase and redemption orders) should 
be mailed to SteinRoe Services Inc. at P.O. Box 8900, Boston, 
Massachusetts 02205.  All distribution and promotional expenses

Institutional Client High Yield Fund.  Foreign securities are 
maintained in the custody of foreign banks and trust companies 
that are members of the Bank's Global Custody Network or foreign 
depositories used by such members.  (See Custodian in the 
Statement of Additional Information.)

            ORGANIZATION AND DESCRIPTION OF SHARES

Stein Roe 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 Stein Roe 
Trust's shareholders or its trustees.  Stein Roe Trust may issue 
an unlimited number of shares, in one or more series as the Board 
may authorize.  Currently, Institutional Client High Yield Fund is 
the only series authorized and outstanding.

Under Massachusetts law, shareholders of a Massachusetts business 
trust such as Stein Roe Trust could, in some circumstances, be 
held personally liable for unsatisfied obligations of Stein Roe 
Trust.  The Declaration of Trust provides that persons extending 
credit to, contracting with, or having any claim against, Stein 
Roe Trust or any particular series shall look only to the assets 
of Stein Roe Trust or of the respective series for payment under 
such credit, contract or claim, and that the shareholders, 
trustees and officers of Stein Roe 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 Stein Roe 
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 Stein Roe 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 Stein Roe 
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 Client 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 Client 
High Yield Fund.  The initial shareholder of Institutional Client 
High Yield Fund approved this policy of permitting Institutional 
Client 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 Client High Yield Fund and High 
Yield Portfolio.  The management and expenses of both 
Institutional Client High Yield Fund and High Yield Portfolio are 
described under Fee Table and Management.  Institutional Client 
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 law trust organized under 
an Agreement and Declaration of Trust ("Declaration of Trust") 
dated August 23, 1993.  The Declaration of Trust of Base Trust 
provides that Institutional Client 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 Client 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 Stein Roe Trust believe 
that neither Institutional Client High Yield Fund nor its 
shareholders will be adversely affected by reason of Institutional 
Client 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 Client 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 
Stein Roe Trust may vote Institutional Client High Yield Fund's 
interests in High Yield Portfolio for such continuation without 
approval of Institutional Client High Yield Fund's shareholders.

The common investment objective of Institutional Client 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 Client High 
Yield Fund's shareholders.

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

If Institutional Client 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 
Client 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 Client 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 
Client High Yield Fund, the Board of Trustees of Stein Roe Trust 
would consider what action might be taken, including changes to 
Institutional Client High Yield Fund's fundamental policies, 
withdrawal of Institutional Client 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 Client High Yield Fund's shareholders.  
Institutional Client 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 Client High Yield Fund's assets could 
result in a distribution in kind of portfolio securities (as 
opposed to a cash distribution) to Institutional Client High Yield 
Fund.  Should such a distribution occur, Institutional Client 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 Client High Yield Fund and could 
affect the liquidity of Institutional Client High Yield Fund.

Each investor in High Yield Portfolio, including Institutional 
Client 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 Client High Yield Fund, could incur different 
administrative fees and expenses than Institutional Client 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 two other investment companies invest in High Yield 
Portfolio:  Stein Roe High Yield Fund, a series of Stein Roe 
Income Trust; and Stein Roe Institutional High Yield Fund, a 
series of Stein Roe Institutional Trust.  Information regarding 
any investment company that may invest in High Yield Portfolio in 
the future may be obtained by writing to SR&F Base Trust, Suite 
3200, One South Wacker Drive, Chicago, Illinois 60606 or by 
calling 800-338-2550.  The Adviser may provide administrative or 
other services to one or more of such investors.

                      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.
