Past performance is no guarantee of future results. Share price and investment
return will vary, so you may have a gain or loss when you sell shares. Total
return performance includes changes in share price and reinvestment of income
and capital gains distributions. Total return figures do not include sales
charges or contingent deferred sales charges (CDSC). Class K shares may be
purchased only through certain intermediaries, including certain bank trust
departments, wrap fee programs and retirement plans. The Advisor currently
limits expenses on Class K shares to 1.10% of average net assets. Absent this
limit, total return would be less. Historical performance for Class K shares
prior to 2/4/98 is based on performance of the SR&F High-Yield Municipals
Portfolio, restated to reflect 12b-1 fees and any other expenses applicable to
that class, without giving any effect to fee waivers and assuming reinvestment
of dividends and capital gains. This graph compares the performance of the Stein
Roe Advisor High-Yield Municipals Fund to the Lehman Brothers Municipal Bond
Index, an unmanaged group of bonds not available for direct investment and not
associated with any Stein Roe fund. The chart assumes a $10,000 investment on
6/30/89, reinvestment of distributions and compares fund performance to an
unmanaged group of fixed income securities that differs from the composition of
any Stein Roe fund. Source of Lipper data: Lipper, Inc., a monitor of mutual

Questions & Answers

An Interview with Maureen Newman Portfolio Manager of
Stein Roe Advisor High-Yield Municipals Fund and SR&F High-Yield
Municipals Portfolio

- --------------------------------------------------------------------------------
                                    Fund Data
   Investment Objective:

   Seeks a high level of tax-free income consistent with capital preservation by
   investing in long-term municipal securities, principally of medium and lower
   quality.

Q: How did the Fund perform in fiscal 1999?

Newman: High-Yield Municipals Fund outperformed the average of its peers for the
12-month period ended June 30, 1999. With dividends reinvested, the Fund had a
total return of 3.08% for the 1999 fiscal year. Of the 3.08% return, 0.50% was
attributable to a one-time revaluation of a portfolio security reflecting the
restructuring of this security. Absent this revaluation, the total return for
the Fund would have been 2.58%. The Lehman Brothers Municipal Bond Index
returned 2.76% for the same period.
     We had a tremendous amount of volatility during the year. Deteriorating
economic conditions in South-east Asia, Latin America and in parts of Europe
last summer triggered a flight to quality movement into U.S. Treasuries. Both
Treasury and municipal bond prices rose through late summer and early fall.
     In late January, bond yields began to rise as reports of strong economic
growth in the fourth quarter proved the economy resilient to international
crises. Municipal bond yields rose as well, but not as much as those of
Treasuries.

Q: You mentioned that January marked a turning point for the municipal bond
market. Since then, how have you adjusted the portfolio's positioning?

Newman: For much of the period, the Fund's duration remained fairly stable. More
recently, however, after U.S. Treasury prices declined--and inversely yields
have risen-- we have modestly lengthened the duration of the Fund in an effort
to take advantage of higher yields on municipal bonds at the long end of the
yield curve.

Q: Have you changed the portfolio's holdings?

Newman: Yes, and quite significantly. Total holdings in the portfolio have
increased to 139, up from just 114 issues last November, when I began managing
the Fund.
     One of our goals has been to further diversify the portfolio's holdings.
Toward that end, we decreased our position in airline bonds, one of the Fund's
largest sector allocations last fall.
     For example, we sold bonds issued by United Airlines and Continental
Airlines. Because credit spreads in this sector did not widen the way they did
in most sectors, these bonds were richly priced, which also made them attractive
sell candidates given the amount of value we were able to lock in.
     We also have been increasing our holdings in selected health care,
education and housing issues--particularly senior housing and multifamily
housing--since these sectors historically have been less cyclical and therefore
may perform well in a slowing economy.

Q: Have you made any shifts in the portfolio's credit quality?

Newman: In keeping with our goal to maintain
a broad mix of bonds, as well as our objective to provide a
high level of tax-free income, we have marginally increased
the portfolio's holdings of lower-rated securities. We also typically have
strong security provisions on these bonds. For example, when we bought Walker
Methodist, (0.4% of net assets), a Minnesota nursing home whose credit quality
was not rated, we got a mortgage on the property to give us added credit
protection.

Q: In what areas of the country are you finding the best opportunities for
yield?

Newman: We hold bonds in many states. However, our practice has been to buy
fewer bonds in New York, California and Massachusetts because the yields in
these high tax-burden states are usually not as great as in other states that
have lower income tax rates or no income tax. Our experience has been that the
higher the state tax rate, the greater the demand for tax-exempt bonds and the
more investors are willing to pay,

Questions & Answers continued

regardless of the bond's coupon. As a result, the issuer historically hasn't had
to offer as much yield to attract investors.

Q: What is your outlook for the year ahead?

Newman: We believe that the U.S. economy will slow down to some extent in the
coming year. This may be driven in part by the effects of a strong U.S. dollar
on overseas trade which has started to moderate growth in the domestic
manufacturing sector. Currently, some U.S. manufacturers believe they are losing
overseas sales because their products are too expensive for foreigners to buy.
     As for High-Yield Municipals Fund, we expect to reduce the Fund's exposure
to cyclical areas and increase holdings in non-cyclical sectors such as schools,
health care and housing. We are also leaning toward slightly lengthening the
Fund's duration to try to take advantage of any potential lowering of interest
rates.

Past performance is no guarantee of future results. Share price and investment
return will vary, so you may have a gain or loss when you sell shares. Total
return includes changes in share price and reinvestment of income and capital
gains distributions, if any. Portfolio holdings are disclosed as a percentage of
SR&F High-Yield Municipals Portfolio as of 6/30/99 and are subject to change.
Investing in high yield bonds involves greater credit risks than investing in
higher-quality bonds. Income distributions are exempt from federal income taxes
but may be subject to the federal alternative minimum tax and state and local
taxes. Capital gains, if any, are also taxable. The Advisor currently limits
expenses to 1.1% of average net assets. Absent this limit total return would be
less. Source of Lipper data: Lipper, Inc.

Notes to Financial Statements
- --------------------------------------------------------------------------------

(All amounts in thousands)


Note 1. Organization
Stein Roe Advisor High-Yield Municipals Fund (the "Fund") is a series of
Liberty-Stein Roe Advisor Trust (the "Trust"), an open-end management investment
company organized as a Massachusetts business trust. The Fund invests
substantially all of its assets in SR&F High-Yield Municipals Portfolio (the
"Portfolio"), which seeks a high level of tax-free income by investing in
long-term municipal securities principally of medium and lower quality.
    The Portfolio is a series of SR&F Base Trust, a Massachusetts common law
trust organized under an Agreement and Declaration of Trust dated August 23,
1993. The Portfolio commenced operations on February 2, 1998. At commencement,
Stein Roe High-Yield Municipals Fund contributed $335,711 in securities and
other assets in exchange for beneficial ownership of the Portfolio. At February
4, 1998, Advisor High-Yield Municipals Fund contributed $100 in securities and
other assets. The Portfolio allocates income, expenses, realized and unrealized
gains and losses to each investor on a daily basis, based on methods approved by
the Internal Revenue Service. At June 30, 1999, Stein Roe High-Yield Municipals
Fund and Advisor High-Yield Municipals Fund owned 99.7 percent and 0.3 percent,
respectively, of the Portfolio.

Note 2. Significant Accounting Policies
The following summarizes the significant accounting policies of the Fund and
Portfolio. These policies are in conformity with generally accepted accounting
principles, which require management to make estimates and assump tions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.

Investment Transactions and Investment Income
    Investment transactions are accounted for on trade date. Interest income,
including premium amortization, is recorded daily on an accrual basis. Realized
gains or losses from investment transactions are reported on a specific
identified cost basis.
    Securities purchased on a when-issued or delayed delivery basis may be
settled a month or more after the transaction date. The values of such
securities are subject to market fluctuations during this period. There were no
when-issued or delayed delivery purchase commitments as of June 30, 1999.

Investment Valuations
    All securities are valued as of June 30, 1999. Municipal securities are
valued at a fair value using a procedure determined in good faith by the Board
of Trustees, which has authorized the use of bid valuations provided by a
pricing service. Other securities and assets are valued at fair value as
determined in good faith by or under the direction of the Board of Trustees.

Futures Contracts
The Portfolio may enter into futures contracts to either hedge against expected
declines of its portfolio securities or as a temporary substitute for the
purchase of individual bonds. Risks of entering into futures contracts include
the possibility that there may be an illiquid market at the time the Portfolio
seeks to close out a contract, and changes in the value of the futures contract
may not correlate with changes in the value of the portfolio securities being
hedged.
    Upon entering into a futures contract, the Portfolio deposits with its
custodian cash or securities in an amount sufficient to meet the initial margin
requirements. Subsequent payments are made or received by the Portfolio equal to
the daily change in the contract value and are recorded as variation margin
payable or receivable and offset in unrealized gains or losses. The Portfolio
recognizes a realized gain or loss when the contract is closed or expires. See
the Portfolio's Portfolio of Investments for a summary of open futures contracts
at June 30, 1999.

Federal Income Taxes
    No provision is made for federal income taxes since (a) the Fund elects to
be taxed as a "regulated investment company" and makes distributions to its
shareholders to be relieved of all federal income taxes under provisions of
current federal tax law; and (b) the Portfolio is treated as a partnership for
federal income tax purposes and all of its income is allocated to its owners
based on methods approved by the Internal Revenue Service.

<PAGE>

Notes to Financial Statements Continued
- --------------------------------------------------------------------------------

The Fund intends to utilize provisions of the federal income tax law that allows
it to carry a realized capital loss forward for eight years following the year
of the loss and offset such losses against any future realized gains. At June
30, 1999, the Fund had capital loss carryforwards as follows:

                    Amount        Year of Expiration
                    -------         --------------

                      $24                2007
                        2                2006

Distributions to Shareholders
Dividends from net investment income are declared daily and paid monthly.
Capital gains distributions, if any, are distributed annually. Dividends are
determined in accordance with income tax principles, which may treat certain
transactions differently than generally accepted accounting principles.
Distributions in excess of tax basis earnings are reported in the financial
statements as a return of capital. Permanent differences in the recognition or
classification of income between the financial statements and tax earnings are
reclassified to paid-in capital.

Note 3. Portfolio Composition
The Portfolio invests in municipal securities including, but not limited to,
general obligation bonds, revenue bonds and escrowed bonds (which are bonds that
have been refinanced, the proceeds of which have been invested in U.S.
government or agency obligations and set aside to pay off the original issue at
the first call date or maturity). Among the Portfolio's investments are
securities that are insured by private insurers who guarantee the payment of
principal and interest in the event of default. At June 30, 1999, investments in
these securities represented 2.0 percent of the Portfolio's net assets. See the
Portfolio's Portfolio of Investments for additional information regarding
portfolio composition.

Note 4. Trustees' Fees and Transactions with Affiliates
The Portfolio pays a monthly management fee and the Fund pays a monthly
administrative fee to Stein Roe & Farnham Incorporated (the "Advisor"), an
indirect, majority-owned subsidiary of Liberty Mutual Insurance Company, for its
services as investment advisor and manager.
    The management fee for the Portfolio is computed at an annual rate of .45 of
1 percent of the first $100 million of average daily net assets, .425 of 1
percent of the next $100 million, and .40 of 1 percent thereafter. The
administrative fee for the Fund is computed at an annual rate of .15 of 1
percent of the first $100 million of average daily net assets, .125 of 1 percent
of the next $100 million, and .10 of 1 percent thereafter.
    The Advisor also provides fund accounting services.
    The Advisor had agreed to reimburse the Fund to the extent that expenses
exceeded 1.10 percent of average annual net assets. This expense limitation
expires on January 31, 2000.
    Shares of the Fund are distributed by Liberty Funds Distributor, Inc. (the
"Distributor"), an indirect, majority-owned subsidiary of Liberty Mutual
Insurance Company. The trustees of the Trust have adopted a plan of distribution
and service pursuant to Rule 12b-1 under the Investment Company Act of 1940 (the
"Plan"). The Plan provides that, as compensation for services and/or
distribution, the Distributor receives from the Fund a fee at an annual rate not
to exceed .25 of 1% of average daily net assets.
    Transfer agent fees are paid to Liberty Funds Services, Inc., formerly
Colonial Investor Services, Inc. (the Transfer Agent), an indirect,
majority-owned subsidiary of Liberty Mutual Insurance Company.
    Certain officers and trustees of the Trust are also officers of the Advisor.
No remuneration was paid to any other trustee or officer of the Trust.

Note 5. Short-Term Debt
To facilitate portfolio liquidity, the Fund and Portfolio maintain borrowing
arrangements under which they can borrow against portfolio securities. There
were no borrowings by either the Fund or the Portfolio during the year ended
June 30, 1999.

Note 6. Investment Transactions
The Portfolio's aggregate cost of purchases and proceeds from sales or maturity
of securities, excluding short-term obligations, for the year ended June 30,
1999, were $60,915 and $91,044, respectively.

 (a)From commencement of operations on February 4, 1998.
 (b)If the Fund had paid all of its expenses and there had been no reimbursement
    by the Advisor, this ratio would have been 5.97% and 16.25% for
    1999 and 1998, respectively.
 (c)Computed giving effect to Advisor's expense limitation undertaking.
 (d)0.50% of the return for the fiscal year ended June 30, 1999 is attributable
    to a one-time revaluation of a portfolio security reflecting the
    restructuring of this security. Absent this revaluation, the total return
    for the Fund for this period would have been 2.58%.
 (e)Annualized.

   Federal Income Tax Information (unaudited)
   100% of the income distributions will be treated as exempt income for federal
income tax purposes.

Report of Independent Auditors

To the Shareholders, Holders of Investors' Beneficial Interests,
and Board of Trustees of Liberty-Stein Roe Advisor Trust and
SR&F Base Trust

Stein Roe Advisor
   High-Yield Municipals Fund
SR&F High-Yield
   Municipals Portfolio

We have audited the accompanying statement of assets and liabilities of Stein
Roe Advisor High-Yield Municipals Fund as of June 30, 1999, the related
statement of operations for the year then ended, the statements of changes in
net assets and financial highlights for the year ended June 30, 1999, and the
period from February 4, 1998 to June 30, 1998. We have also audited the
accompanying statements of assets and liabilities, including the portfolio of
investments, of SR&F High-Yield Municipals Portfolio as of June 30, 1999 and the
related statement of operations for the year then ended, the statements of
changes in net assets and financial highlights for the year ended June 30, 1999
and the period from February 2, 1998 to June 30, 1998. These financial
statements and financial highlights are the responsibility of the Fund's and
Portfolio's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights. Our procedures included confirmation of
securities owned as of June 30, 1999, by correspondence with the custodian and
brokers. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
    In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Stein Roe Advisor High-Yield Municipals Fund and SR&F High-Yield Municipals
Portfolio at June 30, 1999, the results of their operations, the changes in
their net assets and their financial highlights for the periods referred to
above, in conformity with generally accepted accounting principles.
