SUMMARY

Stein Roe Advisor Young Investor Fund ("Advisor Young 
Investor Fund") is a series of Stein Roe Advisor Trust 
("Advisor Trust"), an open-end management investment company 
organized as a Massachusetts business trust.  (See The Fund 
and Organization and Description of Shares.)  This prospectus 
is not a solicitation in any jurisdiction in which shares of 
Advisor Young Investor Fund are not qualified for sale.

Investment Objective and Policies.  The investment objective 
of Advisor Young Investor Fund is to provide long-term 
capital appreciation by investing in common stocks and other 
equity-type securities that the Adviser believes to have 
long-term appreciation potential.  Advisor Young Investor 
Fund invests all of its net investable assets in SR&F Growth 
Investor Portfolio ("Growth Investor Portfolio") which has 
the same investment objective and investment policies 
substantially similar to those of Advisor Young Investor 
Fund.  Growth Investor Portfolio invests primarily in 
securities of companies that are believed to have above-
average growth prospects, many of which affect the lives of 
young people.  

In addition to the investment objective and policies, Advisor 
Young Investor Fund also has an educational objective.  It 
seeks to provide education and insight about mutual funds, 
basic economic principles, and personal finance through a 
variety of educational materials prepared and paid for by 
Advisor Young Investor Fund.

Advisor Young Investor Fund is designed to be appropriate for 
growth-oriented investors of all ages.  Its focus on 
companies that affect the lives of young people and its 
educational objective and materials may make it especially 
appropriate for young people and investors for whom education 
is an important objective.

For a more detailed discussion of the investment objective 
and policies, please see Investment Policies and Portfolio 
Investments and Strategies.  There is, of course, no 
guarantee that Advisor Young Investor Fund or Growth 
Investor Portfolio will achieve their common investment 
objective.

Investment Risks. Advisor Young Investor Fund is designed for 
long-term investors who desire to participate in the stock 
market and places an emphasis on companies that are believed 
to have above-average growth prospects, many of which affect 
the lives of young people.  These investors can accept more 
investment risk and volatility than the stock market in 
general but want less investment risk and volatility than 
aggressive capital appreciation funds.  Growth Investor 
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. Class A shares of Advisor Young 
Investor Fund are available through your full-service 
financial service firm ("FSF").  For information on 
purchasing and redeeming Advisor Young Investor Fund shares, 
please see How to Purchase Shares, How to Sell (Redeem) 
Shares, and Management--Distributor.

Management and Fees.  Stein Roe & Farnham Incorporated (the 
"Adviser") is investment adviser to Growth Investor 
Portfolio.  In addition, it provides administrative services 
to Advisor Young Investor Fund and Growth Investor Portfolio.  
For a description of the Adviser and these service 
arrangements, see Management.

Example.
You would pay the following expenses on a $1,000 investment 
in Class A shares assuming 5% annual return.

Example 1 (assumes redemption at end of period):

            Class A
Period: 
1 Year      $  37
3 Years        72
5 Years        90
10 Years      195

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 Advisor Young 
Investor Fund.  The Fee Table reflects the combined expenses 
of both Advisor Young Investor Fund and Growth Investor 
Portfolio.  Anticipated Total Operating Expenses for Class A 
shares of Advisor Young Investor Fund are annualized 
projections based upon current administrative fees and 
management fees.  Other Expenses are estimated amounts for 
the current fiscal year.  The figures assume that the 
percentage amounts listed under Estimated Annual Fund 
Operating Expenses remain the same during each of the periods 
and that all income dividends and capital gains distributions 
are reinvested in additional shares.

Advisor Young Investor Fund pays the Adviser an 
administrative fee based on its average daily net assets and 
Growth Investor Portfolio pays the Adviser a management fee 
based on its average daily net assets.  The trustees of 
Advisor Trust have considered whether the annual operating 
expenses of Advisor Young Investor Fund, including its share 
of the expenses of Growth Investor Portfolio, would be more 
or less than if Advisor Young Investor Fund invested directly 
in the securities held by Growth Investor Portfolio.  The 
trustees concluded that Advisor Young Investor 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 
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.

Because Advisor Young Investor Fund pays a 12b-1 fee, long-
term investors in Advisor Young Investor Fund may pay more 
over long periods of time in distribution expenses than the 
maximum front-end sales charges permitted by the NASD.  For 
further information on Advisor Young Investor Fund's 12b-1 
fee, see Management--Distributor or call your financial 
representative.


THE FUND

Stein Roe Advisor Young Investor Fund ("Advisor Young 
Investor Fund") is a multi-class series of Advisor Trust, which 
is an open-end management investment company authorized to issue 
shares of beneficial interest in separate series.  

Rather than invest in securities directly, Advisor Young 
Investor Fund seeks to achieve its investment objective by 
using the "master fund/feeder fund structure."  Under that 
structure, a feeder fund and one or more other feeder funds 
pool their assets in a master portfolio that has the same 
investment objective and substantially the same investment 
policies as the feeder funds.  (See Master Fund/Feeder Fund:  
Structure and Risk Factors.)  Advisor Young Investor Fund 
invests all of its net investable assets in SR&F Growth 
Investor Portfolio ("Growth Investor Portfolio"), which is a 
series of SR&F Base Trust ("Base Trust").  

Stein Roe & Farnham Incorporated (the "Adviser") provides 
portfolio management services to Growth Investor Portfolio 
and administrative services to Advisor Young Investor Fund 
and Growth Investor Portfolio. 


INVESTMENT POLICIES

The investment objective of Advisor Young Investor Fund is to 
provide long-term capital appreciation.  Advisor Young 
Investor Fund invests all of its net investable assets in 
Growth Investor Portfolio, which has the same investment 
objective and investment policies substantially similar to 
Advisor Young Investor Fund.  Growth Investor Portfolio seeks 
to achieve this objective by investing primarily in common 
stocks and other equity-type securities that, in the opinion 
of the Adviser, have long-term appreciation potential.

Under normal circumstances, at least 65% of the total assets 
of Growth Investor Portfolio will be invested in securities 
of companies that, in the opinion of the Adviser, directly or 
through one or more subsidiaries, affect the lives of young 
people.  Such companies may include companies that produce 
products or services that young people use, are aware of, or 
could potentially have an interest in.  Although Growth 
Investor Portfolio invests primarily in common stocks and 
other equity-type securities (such as preferred stocks, 
securities convertible into or exchangeable for common 
stocks, and warrants or rights to purchase common stocks), it 
may invest up to 35% of its total assets in debt securities.  

Further information on investment techniques that may be 
employed by Growth Investor Portfolio and the risks 
associated with such techniques may be found under Risks and 
Investment Considerations and Portfolio Investments and 
Strategies in this prospectus and in the Statement of 
Additional Information.  

In addition to the investment objective and policies, Advisor 
Young Investor Fund also has an educational objective.  
Advisor Young Investor Fund seeks to educate its shareholders 
by providing educational materials regarding personal finance 
and investing as well as materials on the Fund and its 
portfolio holdings.


PERFORMANCE INFORMATION

The total return from an investment in a class of shares of 
Advisor Young Investor Fund is measured by the distributions 
received, plus or minus the change in the net asset value per 
share for a given period, assuming reinvestment of all 
distributions on Class A shares and the contingent deferred 
sales charges applicable to the time period quoted.  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.  When the Fund compares the total return of its shares 
to those of other mutual funds or relevant indices, its total 
return may be computed without reflecting any sales charges 
so long as the sales charge is stated separately in 
connection with the comparison.

Comparison of the class's total return with alternative 
investments should consider differences between the class and 
the alternative investments, the periods and methods used in 
calculation of the return being compared including the 
inclusion of initial or contingent deferred sales charges, 
and the impact of taxes on alternative investments. Of 
course, past performance is no guarantee of future results.  
Share prices may vary, and your shares when redeemed may be 
worth more or less than your original purchase price.

The performance of Class A may be compared to various 
indices.  Performance and quotations from various 
publications may be included in sales literature and 
advertisements.

Advisor Young Investor Fund invests all of its net investable 
assets in Growth Investor Portfolio, which has the same 
investment objective and substantially the same investment 
policies as Advisor Young Investor Fund.  Advisor Young 
Investor Fund commenced operations on Feb. 14, 1997, but 
until Jan. 26, 1998, offered only the shares that are now 
designated Class K shares.  The historical performance of 
Class A shares of Advisor Young Investor Fund for all periods 
are based on the performance of Growth Investor Portfolio, 
restated to reflect the sales charges, 12b-1 fees and other 
expenses applicable to the class as set forth in the Fee 
Table, without giving effect to any fee reimbursements 
described therein and assuming reinvestment of dividends and 
capital gains.  Historical performance as restated should not 
be interpreted as indicative of Advisor Young Investor Fund's 
future performance.  Had Class A shares been outstanding, the 
average annual returns for Class A shares as of Sept. 30, 
1997 and Dec. 31, 1997 would have been as follows:

                          Sept. 30     Dec. 31
         1 year            24.00%      23.91%
         3 years           33.26       32.83
         Inception (April
          ( 29, 1994)      29.81       28.85

RISKS AND INVESTMENT CONSIDERATIONS

Advisor Young Investor Fund is designed for long-term 
investors who desire to participate in the stock market and 
places an emphasis on companies that are believed to have 
above-average growth prospects, many of which affect the 
lives of young people.  These investors can accept more 
investment risk and volatility than the stock market in 
general but want less investment risk and volatility than 
aggressive capital appreciation funds.  Growth Investor 
Portfolio usually allocates its investments among a number of 
different industries rather than concentrating in a 
particular industry or group of industries, but this does not 
eliminate all risk.  It will not, however, invest more than 
25% of the total value of its assets (at the time of 
investment) in the securities of companies in any one 
industry.  There can be no guarantee that Advisor Young 
Investor Fund or Growth Investor Portfolio will achieve its 
objective.  Advisor Young Investor Fund also has an 
educational objective.  It seeks to provide education and 
insight about mutual funds, basic economic principles, and 
personal finance through a variety of educational materials 
prepared and paid for by Advisor Young Investor Fund.

Growth Investor Portfolio may invest up to 35% of its total 
assets in debt securities.  Debt securities rated in the 
fourth highest grade may have some speculative 
characteristics, and changes in economic conditions or other 
circumstances may lead to a weakened capacity of the issuers 
of such securities to make principal and interest payments.  
Securities rated below investment grade may possess 
speculative characteristics, and changes in economic 
conditions are more likely to affect the issuer's capacity to 
pay interest or repay principal.

Growth Investor Portfolio may invest in securities of smaller 
emerging companies as well as securities of well-seasoned 
companies of any size.  Smaller companies, however, involve 
higher risks in that they typically have limited product 
lines, markets, and financial or management resources.  In 
addition, the securities of smaller companies may trade less 
frequently and have greater price fluctuation than larger 
companies, particularly those operating in countries with 
developing markets.

Growth Investor Portfolio may invest up to 25% of its total 
assets in foreign securities.  For purposes of this limit, 
foreign securities exclude American Depositary Receipts 
(ADRs), foreign debt securities denominated in U.S. dollars, 
and securities guaranteed by a U.S. person.  Investment in 
foreign securities may represent a greater degree of risk 
(including risk related to exchange rate fluctuations, tax 
provisions, exchange and currency controls, and expropriation 
of assets) than investment in securities of domestic issuers.  
Other risks of foreign investing include less complete 
financial information on issuers, different accounting, 
auditing and financial reporting standards, different 
settlement practices, less market liquidity, more market 
volatility, less developed and regulated markets, and greater 
political instability.  In addition, various restrictions by 
foreign governments on investments by nonresidents may apply, 
including imposition of exchange controls and withholding 
taxes on dividends, and seizure or nationalization of 
investments owned by nonresidents.  Foreign investments also 
tend to involve higher transaction and custody costs.

Further information on investment techniques that may be 
employed by Growth Investor Portfolio may be found under 
Portfolio Investments and Strategies.


INVESTMENT RESTRICTIONS

Each of Advisor Young Investor Fund and Growth Investor 
Portfolio is diversified as that term is defined in the 
Investment Company Act of 1940.  

Neither Advisor Young Investor Fund nor Growth Investor 
Portfolio may invest more than 5% of its assets in the 
securities of any one issuer.  This restriction applies only 
to 75% of the investment portfolio, and does not apply to 
securities of the U.S. Government or repurchase agreements /1/ 
for such securities.  This restriction also does not prevent 
Advisor Young Investor Fund from investing all of its assets 
in shares of another investment company (such as Growth 
Investor Portfolio) having the identical investment objective 
under a master/feeder structure.
- ---------
/1/ A repurchase agreement involves a sale of securities to 
Growth Investor Portfolio in which the seller agrees to 
repurchase the securities at a higher price, which includes 
an amount representing interest on the purchase price, within 
a specified time.  In the event of bankruptcy of the seller, 
Growth Investor Portfolio could experience both losses and 
delays in liquidating its collateral.
- ---------

Neither Advisor Young Investor Fund nor Growth Investor 
Portfolio will acquire more than 10% of the outstanding 
voting securities of any one issuer.  Advisor Young Investor 
Fund may, however, invest all of its assets in shares of 
another investment company having the identical investment 
objective under a master/feeder structure.

While Advisor Young Investor Fund and Growth Investor 
Portfolio may not make loans, each may (1) purchase 
money market instruments and enter into repurchase 
agreements; (2) acquire publicly distributed or privately 
placed debt securities; (3) lend portfolio securities under 
certain conditions; and (4) participate in an interfund 
lending program with other Stein Roe Funds and Portfolios.  
Advisor Young Investor Fund and Growth Investor Portfolio may 
not borrow money, except for nonleveraging, 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.

Growth Investor Portfolio may invest in repurchase 
agreements, provided that it will not invest more than 15% of 
its net assets in illiquid securities, including repurchase 
agreements maturing in more than seven days.

The policies summarized in the second, third, and fourth 
paragraphs under this section and the policy with respect to 
concentration of investments in any one industry described 
under Risks and Investment Considerations are fundamental 
policies of Advisor Young Investor Fund and Growth Investor 
Portfolio and, as such, can be changed only with the approval 
of a "majority of the outstanding voting securities" as 
defined in the Investment Company Act of 1940.  The common 
investment objective of Advisor Young Investor Fund and 
Growth Investor Portfolio is nonfundamental and, as such, may 
be changed by the Board of Trustees without shareholder 
approval.  All of the investment restrictions are set forth 
in the Statement of Additional Information.


PORTFOLIO INVESTMENTS AND STRATEGIES

Debt Securities.  A debt security is an obligation of a 
borrower to make payments of principal and interest to the 
holder of the security.  To the extent Growth Investor 
Portfolio invests in debt securities, such holdings will be 
subject to interest rate risk and credit risk.  Interest rate 
risk is the risk that the value of a portfolio will fluctuate 
in response to changes in interest rates.  Generally, the 
debt component of a portfolio will tend to decrease in value 
when interest rates rise and increase in value when interest 
rates fall.  Credit risk is the risk that an issuer will be 
unable to make principal and interest payments when due.  
Investments in debt securities are limited to those that are 
rated within the four highest grades (generally referred to 
as "investment grade") assigned by a nationally recognized 
statistical rating organization.  Investments in unrated debt 
securities are limited to those deemed to be of comparable 
quality by the Adviser.  Securities rated within the fourth 
highest grade may possess speculative characteristics.  If 
the rating of a security held by Growth Investor Portfolio is 
lost or reduced below investment grade, Growth Investor 
Portfolio is not required to dispose of the security--the 
Adviser will, however, consider that fact in determining 
whether it should continue to hold the security.  When the 
Adviser considers a temporary defensive position advisable, 
Growth Investor Portfolio may invest without limitation in 
high-quality fixed income securities, or hold assets in cash 
or cash equivalents.

Foreign Securities.  Growth Investor Portfolio may invest in 
sponsored or unsponsored ADRs.  In addition to, or in lieu 
of, such direct investment, Growth Investor Portfolio may 
construct a synthetic foreign debt 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 debt 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, Growth 
Investor Portfolio may enter into foreign currency forward 
and futures contracts to hedge the currency risk in 
settlement of a particular security transaction or relative 
to the entire portfolio.  A forward contract to purchase an 
amount of foreign currency sufficient to pay the purchase 
price of securities at settlement date involves the risk that 
the value of the foreign currency may decline relative to the 
value of the dollar prior to the settlement date.  This risk 
is in addition to the risk that the value of the foreign 
security purchased may decline.  Growth Investor Portfolio 
also may enter into foreign currency contracts as a hedging 
technique to limit or reduce exposure of the entire portfolio 
to currency fluctuations.  In addition, Growth Investor 
Portfolio may use options and futures contracts, as described 
below, to limit or reduce exposure to currency fluctuations. 

Convertible Securities.  By investing in convertible 
securities, Growth Investor Portfolio obtains the right to 
benefit from the capital appreciation potential in the 
underlying stock upon exercise of the conversion right, while 
earning higher current income than would be available if the 
stock were purchased directly.  In determining whether to 
purchase a convertible security, the Adviser will consider 
substantially the same criteria that would be considered in 
purchasing the underlying stock.  Although convertible 
securities are frequently rated investment grade, Growth 
Investor Portfolio also may purchase unrated securities or 
securities rated below investment grade if the securities 
meet the Adviser's other investment criteria.  Convertible 
securities rated below investment grade tend to be more 
sensitive to interest rate and economic changes, may be 
obligations of issuers who are less creditworthy than issuers 
of higher-quality convertible securities, and may be more 
thinly traded due to the fact that such securities are less 
well known to investors than either common stock or 
conventional debt securities.  As a result, the Adviser's own 
investment research and analysis tend to be more important 
than other factors in the purchase of convertible securities.

Lending Portfolio Securities; When-Issued and Delayed-
Delivery Securities.  Growth Investor Portfolio may make 
loans of its portfolio securities to broker-dealers and banks 
subject to certain restrictions described in the Statement of 
Additional Information.  Growth Investor Portfolio may 
participate in an interfund lending program, subject to 
certain restrictions described in the Statement of Additional 
Information.  Growth Investor Portfolio may invest in 
securities purchased on a when-issued or delayed-delivery 
basis.  Although the payment terms of these securities are 
established at the time Growth Investor Portfolio 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.  Growth Investor Portfolio will make such 
commitments only with the intention of actually acquiring the 
securities, but may sell the securities before settlement 
date if it is deemed advisable for investment reasons.  

Short Sales Against the Box.  Growth Investor Portfolio may 
sell short securities it owns or has the right to acquire 
without further consideration, using a technique called 
selling short "against the box."  Short sales against the box 
may protect Growth Investor Portfolio 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.  
Growth Investor Portfolio does not expect to commit more than 
5% of its net assets to short sales against the box.  For a 
more complete explanation, please refer to the Statement of 
Additional Information.

Derivatives.  Consistent with its objective, Growth Investor 
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; floating rate 
instruments; and other instruments that securitize assets of 
various types ("Derivatives").  In each case, the value of 
the instrument or security is "derived" from the performance 
of an underlying asset or a "benchmark" such as a security 
index, an interest rate, or a currency.  Growth Investor 
Portfolio does not expect to invest more than 5% of its net 
assets in any type of Derivative except for options, futures 
contracts, and futures options.

In seeking to achieve its desired investment objective, 
provide additional revenue, or hedge against changes in 
security prices, interest rates or currency fluctuations, 
Growth Investor Portfolio may: (1) purchase and write both 
call options and put options on securities, indexes and 
foreign currencies; (2) enter into interest rate, index and 
foreign currency futures contracts; (3) write options on such 
futures contracts; and (4) purchase other types of forward or 
investment contracts linked to individual securities, indexes 
or other benchmarks.  Growth Investor Portfolio may write a 
call or put option only if the option is covered.  As the 
writer of a covered call option, Growth Investor 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 Growth Investor Portfolio seeks to 
close out a position.  In addition, because futures positions 
may require low margin deposits, 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. 

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.

Portfolio Turnover.  Although Growth Investor Portfolio does 
not purchase securities with a view to rapid turnover, there 
are no limitations on the length of time portfolio securities 
must be held.  Accordingly, the portfolio turnover rate may 
vary significantly from year to year, but is not expected to 
exceed 100% under normal market conditions.  A high rate of 
portfolio turnover may result in increased transaction 
expenses and the realization of capital gains and losses.  
(See Distributions and Income Taxes.)


NET ASSET VALUE

Advisor Young Investor Fund determines the net asset value of 
its shares as of the close of regular session trading on the New 
York Stock Exchange ("NYSE") (currently 3:00 p.m., central time 
or 4:00 p.m., eastern time) by dividing the difference between the 
value of its assets and liabilities allocable to that class 
by the number of shares of that class outstanding. Growth Investor 
Portfolio allocates net asset value, income, and expenses to Advisor 
Young Investor Fund and any other of its feeder funds in proportion 
to their respective interests in Growth Investor 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 Advisor Young Investor Fund should be 
determined on any such day, in which case the determination 
will be made at 3:00 p.m., central time or 4:00 p.m., eastern 
time.

Each security traded on a national stock exchange is valued 
at its last sale price on that exchange on the day of 
valuation or, if there are no sales that day, at the latest 
bid quotation.  Each over-the-counter security for which the 
last sale price on the day of valuation is available from 
Nasdaq is valued at that price.  All other over-the-counter 
securities for which reliable quotations are available are 
valued at the latest bid quotation.

Long-term straight-debt obligations and securities 
convertible into stocks are valued at a fair value using a 
procedure determined in good faith by the Board of Trustees.  
Pricing services approved by the Board provide valuations 
(some of which may be "readily available market quotations").  
These valuations are reviewed by the Adviser.  If the Adviser 
believes that a valuation received from the service does not 
represent a fair value, it values the obligation using a 
method that the Board believes represents fair value.  The 
Board may approve the use of other pricing services and any 
pricing service used may employ electronic data processing 
techniques, including a so-called "matrix" system, to 
determine valuations.  Other assets and securities are valued 
by a method that the Board believes represents fair value.


HOW TO PURCHASE SHARES

Shares of each class of Advisor Young Investor Fund are 
offered continuously.  Orders for a class received in good 
order prior to the time at which Advisor Young Investor Fund 
values the shares of that class (or placed with a FSF before 
such time and transmitted by the FSF before Advisor Young 
Investor Fund processes that day's share transactions or at 
such other times as agreed by the parties) will be processed 
based on that day's closing net asset value for the class, 
plus any applicable initial sales charge.

   
With respect to all accounts other than UGMA, UTMA and Education 
IRA accounts, the initial purchase minimum per account is $1,000; 
subsequent investments may be as small as $50.  The minimum 
initial investment for the Fundamatic program (as discussed 
in the Statement of Additional Information) is $50, and the 
minimum initial investment for a retirement account sponsored 
by Liberty Funds Distributor, Inc. (the "Distributor"), an 
affiliate of the Adviser, is $25.  Advisor Young Investor Fund may 
refuse any purchase order for its shares.  See How to Sell (Redeem) 
Shares and the Statement of Additional Information for more 
information.
    

Class A Shares.  Class A shares are offered at net asset 
value.  On purchases of less than $1 million, the Distributor pays 
the FSF a commission of 2.00%.  On purchases of $1 million or more, 
the Distributor pays the FSF a cumulative commission as 
follows:

Amount Purchased   Commission
First $3,000,000     1.00%
Next $2,000,000      0.50
Over $5,000,000      0.251
_______________________
1. Paid over 12 months but only to the extent the shares 
remain outstanding.

In determining the commission applicable to a new purchase 
under the above schedule, the amount of the current purchase 
is added to the current value of shares previously purchased 
and still held by an investor.  If a purchase results in an 
account having a value from $1 million to $5 million, then 
the shares purchased will be subject to a 1.00% contingent 
deferred sales charge payable to the Distributor, if redeemed 
within 18 months from the first day of the month following 
the purchase.  If the purchase results in an account having a 
value in excess of $5 million, the contingent deferred sales 
charge will not apply to the portion of the purchased shares 
comprising such excess amount.

Purchases of $1 million to $5 million are subject to a 1.00% 
contingent deferred sales charge payable to the Distributor 
on redemptions within 18 months from the first day of the 
month following the purchase.  The contingent deferred sales 
charge does not apply to the excess of any purchase over $5 
million. 

Purchases of less than $1 million are subject to a contingent 
deferred sales charge of 2.00% if the shares are redeemed 
within three years from the first day of the month following 
the month in which the purchase was accepted.

General.  All contingent deferred sales charges are deducted 
from the amount redeemed, not the amount remaining in the 
account, and are paid to the Distributor.  Shares issued upon 
distribution reinvestment and amounts representing 
appreciation are not subject to a contingent deferred sales 
charge.  The contingent deferred sales charge is imposed on 
redemptions which result in the account value falling below 
its Base Amount (the total dollar value of purchase payments 
(including initial sales charges, if any) in the account, 
reduced by prior redemptions on which a contingent deferred 
sales charge was paid and any exempt redemptions).  When a 
redemption subject to a contingent deferred sales charge is 
made, generally older shares will be redeemed first.  This may 
mean that the shares redeemed will be those closest to being 
outside the period in which the contingent deferred sales charge 
is in effect.  See the Statement of Additional Information for 
more information.

FSFs may receive different compensation rates for selling 
different classes of shares.  The Distributor may pay 
additional compensation for FSFs which have made or may make 
significant sales.  See the Statement of Additional 
Information for more information.

Special Purchase Programs.  Advisor Young Investor Fund 
allows certain investors or groups of investors to purchase 
shares with reduced or without initial or contingent deferred 
sales charges.  The programs are described in the Statement 
of Additional Information under Purchases and Redemptions--
Special Purchase Programs/Investor Services.  

Conditions of Purchase.  Each purchase order for Advisor 
Young Investor Fund must be accepted by an authorized officer 
of the Distributor or its authorized agent and is not binding 
until accepted and entered on the books of Advisor Young 
Investor Fund.  Advisor Trust reserves the right not to 
accept any purchase order that it determines not to be in the 
best interests of Advisor Trust or of Advisor Young Investor 
Fund's shareholders.  

To reduce the volume of mail you receive, only one copy of certain 
Materials, such as prospectuses and shareholder reports, will be 
mailed to your household (same address).  Please call 800-322-0593 if 
you wish to receive additional copies free of charge.

Shareholder Services and Account Fees.  A variety of 
shareholder services are available.  For more information 
about these services or your account call (800) 345-6611.  
Some services are described in the attached account 
application.  A Shareholder's Manual explaining all available 
services will be provided upon request.  

With respect to all accounts other than UGMA, UTMA and Education 
IRA accounts, in June of any year, the Fund may deduct $10 (payable 
to the Transfer Agent) from accounts valued at less than $1,000 
unless the account value has dropped below $1,000 solely as a 
result of share value depreciation.  Shareholders will 
receive 60 days' written notice to increase the account value 
before the fee is deducted.  The Fund may also deduct annual 
maintenance and processing fees (payable to the Transfer 
Agent) in connection with certain retirement plan accounts.  
(See Purchases and Redemptions--Special Purchase 
Programs/Investor Services in the Statement of Additional 
Information.)


HOW TO SELL (REDEEM) SHARES

Selling Shares Directly to Advisor Young Investor Fund.  You 
may redeem all or a portion of your shares by submitting a 
written request, in English, in good order.  Send a signed letter of 
instruction to the Transfer Agent.  The sale price is the net 
asset value (less any contingent deferred sales charge) next 
determined after receipt of your redemption request in good 
order.  Signatures must be guaranteed by a bank, a member 
firm of a national stock exchange or another eligible 
guarantor institution.  Additional documentation is required 
for sales by corporations, agents, fiduciaries, surviving 
joint owners and individual retirement account holders.  For 
details contact:

Colonial Investors Service Center, Inc.
P.O. Box 1722
Boston, MA 02105-1722
(800) 345-6611

Selling Shares through FSFs.  FSFs must receive requests 
prior to the time at which Advisor Young Investor Fund values 
its shares to receive that day's price, are responsible for 
furnishing all necessary documentation to the Transfer Agent, 
and may charge for this service.  Your FSF may be closed on 
days when the NYSE is open.  As a result, prices for shares 
may be significantly affected on days when you have no access 
to your FSF to sell shares.  If you wish to sell shares 
through your FSF, please contact it for instructions.

Exchange Privilege.  For a period of 90 days following the 
purchase of Class A shares of Advisor Young Investor Fund, 
exchanges at net asset value may be made among Class A shares 
of Colonial Municipal Money Market Fund or Colonial Government 
Money Market Fund (or its successor).  Thereafter, exchanges at 
net asset value may be made among Class A shares of any other 
fund that is a series of Advisor Trust or of most funds advised 
by Colonial Management Associates, Inc. or distributed by the 
Distributor, each an affiliate of the Adviser.  A contingent 
deferred sales charge, if any, continues to apply to the 
exchanged shares.  For more information on the Colonial Funds, see 
your financial adviser or call (800) 426-3750.  Not all Advisor 
Trust Funds offer Class A shares.  An exchange transaction is a 
sale and purchase of shares for federal income tax purposes and may 
result in capital gain or loss.  Before exchanging into 
another fund, you should obtain the prospectus for the fund 
in which you wish to invest and read it carefully.  The 
registration of the account to which you are making an 
exchange must be exactly the same as that of the account from 
which the exchange is made.  Advisor Young Investor Fund 
reserves the right to suspend, limit, modify, or terminate 
the exchange privilege (including the telephone exchange 
privilege) or its use in any manner by any person or class.  
Advisor Young Investor Fund will terminate the exchange 
privilege as to a particular shareholder if the Adviser 
determines, in its sole and absolute discretion, that the 
shareholder's exchange activity is likely to adversely impact 
the Adviser's ability to manage the investment portfolio in 
accordance with the investment objective or otherwise harm 
Advisor Young Investor Fund or its remaining shareholders.

Shares will continue to age without regard to the exchange 
for the purpose of determining the contingent deferred sales 
charge, if any, upon redemption.

An exchange from a money market fund into a non-money market 
fund will be at the applicable offering price next determined 
(including sales charge), except for amounts on which an 
initial sales charge was paid.  Non-money market fund shares 
must be held for five months before qualifying for exchange 
into a fund with a higher sales charge, after which an 
exchange is made at the net asset value next determined.  
Exchanges of Class A shares are not subject to the contingent 
deferred sales charge.  However, if shares received in the 
exchange are redeemed within three years after the original 
purchase, a contingent deferred sales charge will be assessed 
using the schedule of the fund into which the original 
investment was made.

Telephone Transactions.  Shareholders and/or their financial 
advisers are automatically eligible to exchange shares and 
redeem shares up to $50,000 by calling (800) 422-3737 any 
business day between 10:00 a.m., central time (or 9:00 a.m., 
eastern time) and the time as of which Advisor Young Investor 
Fund values its shares.  Telephone redemption privileges for 
larger amounts may be elected on the account application.  
Generally, other than as set forth herein, you will be 
limited to four telephone exchange round-trips per year, and 
Advisor Young Investor Fund may refuse requests for telephone 
exchanges in excess of four round-trips.

Advisor Trust reserves the right to terminate at any time and 
without prior notice the use of the telephone exchange by any 
person or class of persons.  Advisor Trust believes that use 
of the telephone exchange by investors utilizing market-
timing strategies adversely affects the Advisor Trust Funds.  
Therefore, regardless of the number of telephone exchange 
round-trips made by an investor, Advisor Trust generally will 
not honor requests for telephone exchanges by shareholders 
identified by Advisor Trust as "market-timers" if the 
officers of the Trust determine the order not to be in the 
best interests of the Trust or its shareholders.  Advisor 
Trust generally identifies as a "market-timer" an investor 
whose investment decisions appear to be based on actual or 
anticipated near-term changes in the securities markets 
rather than other investment considerations.

The Transfer Agent employs procedures reasonably designed to 
confirm that instructions communicated by telephone are 
genuine.  If Advisor Young Investor Fund and/or the Transfer 
Agent does not follow reasonable procedures for protecting 
shareholders against loss on telephone transactions, it may 
be liable for any losses due to unauthorized or fraudulent 
instructions.  Such procedures include restrictions on where 
proceeds of telephone redemptions may be sent, limitations on 
the ability to redeem by telephone shortly after an address 
change, recording of telephone lines and requirements that 
the redeeming shareholder and/or his/her financial adviser 
provide certain identifying information.  Shareholders and/or 
their financial advisers wishing to redeem or exchange shares 
by telephone may experience difficulty in reaching Advisor 
Young Investor Fund at the toll free number during periods of 
drastic economic or market changes.  In that event, 
shareholders and/or their financial advisers should follow 
the procedures for redemption or exchange by mail as 
described above under  How to Sell (Redeem) Shares.  The 
Transfer Agent and Advisor Young Investor Fund reserve the 
right to change, modify or terminate the telephone redemption 
or exchange services at any time upon prior written notice to 
shareholders.  Shareholders and/or their financial advisers 
are not obligated to transact by telephone.

General Redemption Policies.  Shares of Advisor Young 
Investor Fund may be sold on any day the NYSE is open, either 
directly with Advisor Young Investor Fund or through your 
FSF. Advisor Trust will pay redemption proceeds (less any 
applicable contingent deferred sales charge) as soon as 
practicable, generally within seven days after proper 
instructions are received.  However, for shares recently 
purchased by check, Advisor Young Investor Fund will delay 
sending proceeds for 15 days in order to protect the Fund 
against financial losses and dilution in net asset value 
caused by dishonored purchase payment checks.  To avoid delay 
in payment, investors are advised to purchase shares 
unconditionally, such as by certified check or other 
immediately available funds.  Advisor Trust cannot accept a 
redemption request that specifies a particular date or price 
for redemption or any special conditions.  

The price at which your redemption order will be executed is 
the net asset value next determined after receipt of your 
redemption request in good order by Advisor Young Investor 
Fund.  (See Net Asset Value.)  Because the redemption price 
you receive depends upon Advisor Young Investor 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, may result in a realized capital gain or loss and may 
be subject to a contingent deferred sales charge.  The 
contingent deferred sales charge may be waived under certain 
circumstances.  See the Statement of Additional Information 
for more information.


DISTRIBUTIONS AND INCOME TAXES

Distributions.  Income dividends are declared and paid 
annually.  Advisor Young Investor 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 
12-month period ended Oct. 31 in that year.  Advisor Young 
Investor Fund intends to distribute any undistributed net 
investment income and net realized capital gains in the 
following year.

All income dividends and capital gains distributions on 
shares of Advisor Young Investor Fund will be reinvested in 
additional shares of the same class of Advisor Young Investor 
Fund unless you elect to have distributions paid by check. 
Reinvestment normally occurs on the payable date.  Regardless 
of your election, distributions of $10 or less will not be 
paid by check to the shareholder, but will be reinvested in 
additional shares of the same class of Advisor Young Investor 
Fund at net asset value.  If you have elected to receive 
dividends and/or capital gains distributions in cash and the 
postal or other delivery service selected by the Transfer 
Agent is unable to deliver checks to your address of record, 
your distribution option will automatically be converted to 
having all dividend and other distributions reinvested in 
additional shares.  No interest will accrue on amounts 
represented by uncashed distribution or redemption checks.  
To change your election, call the Transfer Agent for 
instructions. 

Income Taxes.  For federal income tax purposes, Advisor Young 
Investor Fund is treated as a separate taxable entity 
distinct from the other series of Advisor Trust.  Advisor 
Young Investor Fund 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 gains that is distributed 
to shareholders.

Generally distributions are taxable as ordinary income, 
except that any distributions of net long-term capital gains 
will be taxed as such.  However, distributions to plans that 
qualify for tax-exempt treatment under federal income tax 
laws will not be taxable.  Special tax rules apply to 
investments through such plans.

The Taxpayer Relief Act of 1997 (the "Act") reduced from 28% 
to 20% the maximum tax rate on long-term capital gains.  This 
reduced rate generally applies to securities held for more 
than 18 months and sold after July 28, 1997, and securities 
held for more than one year and sold between May 6, 1997 and 
July 29, 1997.

If you buy shares shortly before a distribution is declared, 
the distribution will be taxable although it is, in effect, a 
partial return of the amount invested.

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.


MANAGEMENT

Trustees and Investment Adviser.  The Board of Trustees of 
Advisor Trust and the Board of Trustees of Base Trust have 
overall management responsibility for Advisor Young Investor 
Fund and Growth Investor Portfolio, respectively.  See 
Management in the Statement of Additional Information for the 
names of and other information about the trustees and 
officers.  Since Advisor 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 Advisor Young Investor Fund and Growth 
Investor Portfolio and other feeder funds investing in Growth 
Investor Portfolio that share a common Board of Trustees with 
Advisor Trust and Base Trust.

The Adviser, Stein Roe & Farnham Incorporated, One South 
Wacker Drive, Chicago, Illinois 60606, is responsible for 
managing the investment portfolio of Growth Investor 
Portfolio and the business affairs of Advisor Young Investor 
Fund, Growth Investor Portfolio, Advisor Trust, and Base 
Trust, subject to the direction of the respective Board.  The 
Adviser is registered as an investment adviser under the 
Investment Advisers Act of 1940.  The Adviser and its 
predecessor have advised and managed mutual funds since 1949.  
The Adviser is a wholly owned indirect subsidiary of Liberty 
Financial Companies, Inc. ("Liberty Financial"), which in 
turn is a majority owned indirect subsidiary of Liberty 
Mutual Insurance Company.

Portfolio Managers.  Erik P. Gustafson and David P. Brady 
have been portfolio managers of Growth Investor Portfolio 
since its inception in 1997 and had managed its predecessor 
since Feb. 1995 and Mar. 1995, respectively.  As of Sept. 30, 
1997, Messrs. Gustafson and Brady were responsible for co-
managing $1.2 billion and $475 million in mutual fund net 
assets, respectively.  Mr. Gustafson is a senior vice 
president of the Adviser and Mr. Brady is a vice president of 
the Adviser.  Before joining the Adviser, Mr. Gustafson was 
an attorney with Fowler, White, Burnett, Hurley, Banick & 
Strickroot from 1989 to 1992.  He holds a B.A. from the 
University of Virginia (1985) and M.B.A. and J.D. degrees 
from Florida State University (1989).  Mr. Brady, who joined 
the Adviser in 1993, was an equity investment analyst with 
State Farm Mutual Automobile Insurance Company from 1986 to 
1993.  A chartered financial analyst, Mr. Brady earned a B.S. 
in Finance, graduating Magna Cum Laude, from the University 
of Arizona (1986), and an M.B.A. from the University of 
Chicago (1989). 

Fees and Expenses.  The Adviser is entitled to receive a 
monthly administrative fee from Advisor Young Investor Fund, 
computed and accrued daily, at an annual rate of 0.20% of the 
first $500 million of average net assets, 0.15% of the next 
$500 million, and 0.125% thereafter; and a monthly management 
fee from Growth Investor Portfolio, computed and accrued 
daily, at an annual rate of 0.60% of the first $500 million 
of average net assets, 0.55% of the next $500 million, and 
0.50% thereafter.  However, as noted above under Fee Table, 
the Adviser may voluntarily undertake to reimburse Advisor 
Young Investor Fund for a portion of its operating expenses 
and its pro rata share of Growth Investor Portfolio's 
operating expenses.  For the fiscal year ended Sept. 30, 
1997, Advisor Young Investor Fund's administrative fee, in 
addition to the pro rata portion of Growth Investor 
Portfolio's management fees, was 0.00% of average net assets, 
after the fee waiver.

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

In addition, the Adviser is free to make additional payments 
out of its own assets to promote the sale of shares of 
Advisor Young Investor Fund.

Portfolio Transactions.  The Adviser places the orders for 
the purchase and sale of portfolio securities and options and 
futures contracts for Growth Investor Portfolio.  In doing 
so, the Adviser seeks to obtain the best combination of price 
and execution, which involves a number of judgmental factors.

Transfer Agent and Shareholder Services.  Colonial Investors 
Service Center, Inc. ("Transfer Agent"), P.O. Box 1722, 
Boston, MA 02105-1722, an indirect subsidiary of Liberty 
Financial, is the agent of Advisor Trust for the transfer of 
shares, disbursement of dividends, and maintenance of 
shareholder accounting records. 

Some FSFs that maintain nominee accounts with Advisor Young 
Investor Fund for their clients who are Fund shareholders may 
be paid a fee by the Transfer Agent for shareholder servicing 
and accounting services they provide with respect to the 
underlying Fund shares.  

   
Distributor.  The shares of Advisor Young Investor Fund are 
offered for sale through Liberty Funds Distributor, Inc.  
The Distributor is a subsidiary of Colonial Management 
Associates, Inc., which is an indirect subsidiary of Liberty 
Financial.  The business address of the Distributor is One 
Financial Center, Boston, Massachusetts 02111-2621; however, 
all Fund correspondence (including purchase and redemption 
orders) should be mailed to Colonial Investors Service 
Center, Inc., the Transfer Agent, at P.O. Box 1722, Boston, 
Massachusetts 02105-1722.
    

The trustees of Advisor Trust have adopted a plan pursuant to 
Rule 12b-1 under the Investment Company Act of 1940 ("Plan").  
The Plan provides that, as compensation for personal service 
and/or the maintenance of shareholder accounts, the 
Distributor receives from Advisor Young Investor Fund a 
service fee at an annual rate not to exceed 0.25% of the 
Fund's net assets attributed to Class A shares.  The Plan 
also provides that, as compensation for expenses related to 
the promotion and distribution of shares of Advisor Young 
Investor Fund including its expenses related to the sale and 
promotion of Advisor Young Investor Fund shares, the 
Distributor receives from Advisor Young Investor Fund a 
distribution fee at an annual rate not exceeding 0.10% of the 
average net assets attributed to Class A shares.  At this 
time, the Distributor has voluntarily agreed to limit the 
Class A distribution fee  to 0.05% annually.  The Distributor 
may terminate this voluntary limitation without shareholder 
approval.  The Distributor generally pays this compensation 
to institutions that distribute Advisor Young Investor Fund 
shares and provide services to Advisor Young Investor Fund 
and its shareholders.  Those institutions may use the 
payments for, among other purposes, compensating employees 
engaged in sales and/or shareholder servicing. The amount of 
fees paid by Advisor Young Investor Fund during any year may 
be more or less than the cost of distribution or other 
services provided to Advisor Young Investor Fund.  NASD rules 
limit the amount of annual distribution fees that may be paid 
by a mutual fund and impose a ceiling on the cumulative sales 
charges paid. 

Custodian.  State Street Bank and Trust Company (the "Bank"), 
225 Franklin Street, Boston, Massachusetts 02101, is the 
custodian for Advisor Young Investor Fund and Growth Investor 
Portfolio.  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

Advisor 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 Advisor Trust's shareholders or its trustees.  
Advisor Trust may issue an unlimited number of shares, in one 
or more series as the Board may authorize.  Currently, ten 
series are authorized and outstanding.

Under Massachusetts law, shareholders of a Massachusetts 
business trust such as Advisor Trust could, in some 
circumstances, be held personally liable for unsatisfied 
obligations of the trust.  The Declaration of Trust provides 
that persons extending credit to, contracting with, or having 
any claim against, Advisor Trust or any particular series 
shall look only to the assets of Advisor Trust or of the 
respective series for payment under such credit, contract or 
claim, and that the shareholders, trustees and officers 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 Advisor 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 Advisor 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 Advisor 
Trust also is 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 series was unable to meet 
its obligations.

As a business trust, Advisor 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.

MASTER FUND/FEEDER FUND: STRUCTURE AND RISK FACTORS

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

Growth Investor 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 Aug. 23, 1993.  The 
Declaration of Trust of Base Trust provides that Advisor 
Young Investor Fund and other investors in Growth Investor 
Portfolio will each be liable for all obligations of Growth 
Investor Portfolio that are not satisfied by the Portfolio.  
However, the risk of Advisor Young Investor Fund incurring 
financial loss on account of such liability is limited to 
circumstances in which both inadequate insurance existed and 
Growth Investor Portfolio itself was unable to meet its 
obligations.  Accordingly, the trustees of Advisor Trust 
believe that neither Advisor Young Investor Fund nor its 
shareholders will be adversely affected by reason of Advisor 
Young Investor Fund's investing in Growth Investor Portfolio.  

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

The common investment objective of Advisor Young Investor 
Fund and Growth Investor Portfolio is nonfundamental and may 
be changed without shareholder approval.  The fundamental 
policies of Advisor Young Investor Fund and the corresponding 
fundamental policies of Growth Investor Portfolio can be 
changed only with shareholder approval.  Class A shareholders 
may incur a contingent deferred sales charge if they redeem 
shares in response to a change in investment objective.

If Advisor Young Investor Fund, as a Portfolio investor, is 
requested to vote on a proposed change in fundamental policy 
of Growth Investor Portfolio or any other matter pertaining 
to Growth Investor Portfolio (other than continuation of the 
business of Growth Investor Portfolio after withdrawal of 
another investor), Advisor Young Investor Fund will solicit 
proxies from its shareholders and vote its interest in Growth 
Investor Portfolio for and against such matters 
proportionately to the instructions to vote for and against 
such matters received from Advisor Young Investor Fund 
shareholders.  Advisor Young Investor Fund will vote shares 
for which it receives no voting instructions in the same 
proportion as the shares for which it receives voting 
instructions.  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 Growth Investor 
Portfolio investors.  If other investors hold a majority 
interest in Growth Investor Portfolio, they could have voting 
control over Growth Investor Portfolio.  

In the event that Growth Investor Portfolio's fundamental 
policies were changed so as to be inconsistent with those of 
Advisor Young Investor Fund, the Board of Trustees of Advisor 
Trust would consider what action might be taken, including 
changes to Advisor Young Investor Fund's fundamental 
policies, withdrawal of Advisor Young Investor Fund's assets 
from Growth Investor 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 Advisor Young Investor Fund's 
shareholders.  Advisor Young Investor 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 Advisor Young 
Investor Fund's assets could result in a distribution in kind 
of portfolio securities (as opposed to a cash distribution) 
to Advisor Young Investor Fund.  Should such a distribution 
occur, Advisor Young Investor 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 Advisor Young 
Investor Fund and could affect the liquidity of Advisor Young 
Investor Fund.

Each investor in Growth Investor Portfolio, including Advisor 
Young Investor Fund, may add to or reduce its investment in 
Growth Investor Portfolio on each day the NYSE is open for 
business.  The investor's percentage of the aggregate 
interests in Growth Investor 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 Growth Investor 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 Growth Investor 
Portfolio effected on such day; and (ii) the denominator of 
which is the aggregate beginning of the day net asset value 
of Growth Investor 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 Growth Investor 
Portfolio by all investors in Growth Investor Portfolio.  The 
percentage so determined will then be applied to determine 
the value of the investor's interest in Growth Investor 
Portfolio as of the close of business.

Base Trust may permit other investment companies and/or other 
institutional investors to invest in Growth Investor 
Portfolio, but members of the general public may not invest 
directly in Growth Investor Portfolio.  Other investors in 
Growth Investor Portfolio are not required to sell their 
shares at the same public offering price as Advisor Young 
Investor Fund and might incur different administrative fees 
and expenses than Advisor Young Investor Fund.  Therefore, 
Advisor Young Investor Fund shareholders might have different 
investment returns than shareholders in another investment 
company that invests exclusively in Growth Investor 
Portfolio.  Investment by such other investors in Growth 
Investor 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 Growth Investor Portfolio could result in 
untimely liquidations of Growth Investor Portfolio's security 
holdings, loss of investment flexibility, and increases in 
the operating expenses of Growth Investor Portfolio as a 
percentage of its net assets.  As a result, Growth Investor 
Portfolio's security holdings may become less diverse, 
resulting in increased risk.

Growth Investor Portfolio commenced operations in Feb. 1997 
when Stein Roe Young Investor Fund, a mutual fund that, 
together with its corporate predecessor, had invested 
directly in securities since 1958, converted into a feeder 
fund by investing all of its assets in the Portfolio.  
Currently Stein Roe Young Investor Fund, which is a series of 
Stein Roe Investment Trust, is the only other investment 
company investing in Growth Investor Portfolio.  Information 
regarding any investment company that may invest in Growth 
Investor 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.
