PORTFOLIO MANAGER'S DISCUSSION
Stein Roe Special Venture Fund, Variable Series
- --------------------------------------------------------------------------------


Q: HOW DID THE FUND PERFORM?

A: For the six-month period ended June 30, 1998, Stein Roe Special Venture Fund,
Variable Series returned -6.25 percent, underperforming the Russell 2000 Index
and the Lipper small-cap peer group which returned 4.93 percent and 6.02
percent, respectively. Small-cap stocks continued to lag their larger-cap
counterparts throughout the period despite relatively better earnings growth in
the small stock sector. The Fund underperformed its peers as many of its
holdings suffered from a "ripple effect" from reduced demand from Asian markets.

Q: WHAT WAS THE PREMISE FOR SMALL-CAP STOCK UNDERPERFORMANCE?

A: Small-cap stocks outperformed large-cap stocks from April 1997 through
October 1997 until the currency crisis in Asia caused many investors to flee to
the relative safety of large-cap stocks. This "safety in size" mentality left
small-cap stocks lagging their large-cap counterparts ever since. For the
six-month period, the Russell 2000, the proxy for the small-cap market, trailed
the large-cap S&P 500 benchmark by 12.79 percentage points.

The second quarter of 1998 was the most difficult quarter for small-cap stocks
this decade. The majority of stock market purchasing has favored large-cap
stocks, with influences from indexing, mutual fund activity, and large foreign
institutions. Small stock prices have suffered from indifference. If past phases
of market activity are any indication of what's to come, investors should again
favor the excellent growth potential and reasonable valuations of the small-cap
sector. In the mean time, we're using this opportunity to purchase attractive
stocks at inexpensive prices.

Q: WHAT SECTORS UNDERPERFORMED?

A: Two sectors that underperformed for the Fund were energy and technology. Our
oil and gas exploration and production holdings, including Barrett Resources and
Meridian Resources (0.3 percent, and 1.4 percent of total net assets), suffered
from the weakened outlook for oil and gas prices. During the first quarter, we
reduced our exposure to the energy sector from 5.7 percent to 1.7 percent of
total net assets (an underweighted position relative to the Russell 2000),
because, in our opinion, energy prices still look uncertain going forward.

Technology holdings that impacted the Fund's performance included AVX (1.8
percent of total net assets), Kent Electronics (1.8 percent of total net
assets), Artesyn Technologies (2.3 percent of net assets), and Andrew
Corporation which we sold out of before the end of the period. Earnings growth
expectations were reduced on these companies as demand from Asia slowed.

Q: WHEN DO YOU SELL DISAPPOINTING STOCKS?

A: We generally only sell a stock if there is a sudden change in business
strategy that suggests to us that company or industry fundamentals are
deteriorating. We thoroughly research each purchase so that our buying is based
on long-term fundamentals. However, disappointing short-term performance will
trigger a fundamental review of a stock.

Q: WHAT HOLDINGS PERFORMED WELL?

A: LaSalle Partners (2.4 percent of total net assets) rose 24.7 percent over the
past six months reflecting higher commercial real estate activity. Xomed
Surgical Products (4.8 percent of total net assets) increased 24.2 percent as
its less-invasive surgical products market share rose in

the ears, nose and throat market. Also, Metamor Worldwide (2.9 percent of total
net assets), benefiting from the trend toward outsourcing of information
technology staff and consulting services, increased 36.7 percent over the last
six months.

Q: WHAT IS YOUR OUTLOOK FOR THE SMALL-CAP MARKET? BASED ON THAT, WHAT IS YOUR
OUTLOOK FOR THE FUND?

A: Small-cap stocks are as cheap as they've been at any time during the past
twenty years, relative to larger-cap stocks. The earnings growth outlook for
small stocks remains favorable. This suggests to us that this sector has the
potential for long-term outperformance with moderate shorter-term risk.

We continue to add to our positions in companies that have experienced
management, financial strength and evidence of a sustainable competitive
advantage.

PORTFOLIO MANAGER'S DISCUSSION
Stein Roe Growth Stock Fund, Variable Series
- --------------------------------------------------------------------------------



Q: HOW DID THE FUND PERFORM?

A: Stein Roe Growth Stock Fund, Variable Series performed well during the
six-month period ending June 30, 1998. The Fund's total return of 18.68 percent
beat both the Lipper growth fund peer group return of 15.65 percent and the S&P
500 Index return of 17.72 percent for the same period.

Q: WHAT CONTRIBUTED TO PERFORMANCE?

A: For the past six months the U.S. economy has been strong amid continued
global affects from the Asian crisis. Large-cap stocks historically perform well
in a strong economy. They also are considered the equity investment of choice
when markets are volatile because of their historical stability and liquidity.
Combined, these two factors helped boost the performance of the Fund.

Q: WHAT SECTORS PERFORMED THE BEST?

A: The U.S. consumer has benefited from extremely favorable economic conditions.
Therefore, retail companies have benefited from strong consumer spending. The
Fund's performance was supported by holdings in global consumer franchises such
as Gillette, Procter & Gamble and Walt Disney (3.1 percent, 3.2 percent and 2.1
percent of total net assets, respectively). Other top performers in the retail
sector were Home Depot and Kohl's. Home Depot's profits were driven by record
sales of new and existing homes (3.3 percent of total net assets). Kohl's, a
Midwestern value-priced retailer (3.3 percent of total net assets), is
benefiting from its East Coast expansion. Our health care holdings Merck,
Medtronic and Pfizer (2.6 percent, 3.1 percent, and 3.4 percent of total net
assets, respectively) continued to perform well due to their strong product
lines. Rounding out top performers were telecommunications equipment companies
Lucent Technologies, Cisco Systems and LM Ericsson Telecommunications (3.9
percent, 4.4 percent and 3.2 percent of total net assets, respectively). These
companies continue to benefit from the dramatic worldwide need to upgrade
telecommunications infrastructures to accommodate voice, video and data
services.

Q: WHAT SECTORS UNDERPERFORMED?

A: Oil services was a disappointing sector as companies suffered from decreasing
oil prices. In this sector, holdings Schlumberger Limited and R&B Falcon
underperformed (2.2 percent and 0.9 percent of total net assets, respectively).
However, our long-term outlook for this area is favorable, so we plan to
continue to hold these companies.

Q: TECHNOLOGY IS ONE OF YOUR TOP SECTORS. HOW DID YOUR HOLDINGS FARE?

A: The first quarter is usually tough for certain technology companies, but this
year's seasonal slowness was exacerbated by the turmoil in Asia. Some of the
Fund's holdings suffered due to earnings concerns as well, such as Motorola --
which we sold, and Intel -- which we continue to hold (2.3 percent of total net
assets). Our long-term outlook for the technology sector overall continues to be
favorable because we believe companies will continue to purchase new technology
in order to compete globally. We invest in technology companies that we think
have excellent product lines and are less susceptible to economic downturns
because of their market dominance. For example, we continue to hold this
microprocessor manufacturer because, like Coca-Cola (3.0 percent of total net
assets) and Gillette, Intel is the dominant company in its industry around the
globe.

PORTFOLIO MANAGER'S DISCUSSION (continued)
Stein Roe Growth Stock Fund, Variable Series
- --------------------------------------------------------------------------------



Q: WHAT ARE SOME NEW NAMES WE'LL SEE IN THE PORTFOLIO?

A: We established positions in Time Warner, NationsBank and Peoplesoft during
the period (3.4 percent, 1.8 percent and 1.6 percent of total net assets,
respectively) because we believe these companies will be able to grow their
earnings consistently over time.

Q: WHAT DID YOU SELL DURING THE PERIOD?

A: We sold our position in McDonald's after it experienced continued decreases
in same-store sales growth. We also sold Wells Fargo, Baker-Hughes and
Thermo-Electron due to weaker than expected earnings.

Q: WHAT INVESTMENT THEMES DO YOU PLAN TO FOLLOW GOING FORWARD?

A: We intend to take advantage of the trend toward global democracy and we will
continue to look for companies that will benefit from increased global consumer
demand. Greater disposable income leads to greater consumer demand for products.
And our belief is that global consumer franchises that perfect their business in
multiple markets stand to benefit tremendously from this opportunity. For
example, we believe Procter & Gamble is the most globally dominant company
within its respective markets, and it is one of the portfolio's largest
holdings.

We also will continue to focus on companies that we believe stand to benefit
from the aging of the baby boomer generation. As these 80 million consumers age,
they're going to require more and better health care. For, example, we believe
pharmaceutical maker Eli Lilly (2.6 percent of total net assets) should be
driven by sales of Evista, which is its osteoporosis drug for post-menopausal
women. As market segments change, product demand will change. Therefore, we will
continue to monitor the market and invest in companies that we believe are
positioned to leverage this trend.

Q: WHAT'S YOUR OUTLOOK?

A: Our long-term outlook for large-cap companies remains positive despite the
possibility that growth for some of these companies may decelerate sometime in
the future due to the Asian crisis. Therefore, we will focus on companies that
have proved their ability to deliver consistent earnings despite the overall
strength or weakness of the general market. We believe that the U.S. economy
will slow in the second half of 1998. If that does occur, then growth stocks may
continue to outperform as investors pay a premium for the consistent earnings
growth they can provide.

PORTFOLIO MANAGER'S DISCUSSION
Stein Roe Balanced Fund, Variable Series
- --------------------------------------------------------------------------------



Q: HOW DID THE FUND PERFORM?

A: The Fund returned 6.56 percent for the six-month period ended June 30, 1998,
underperforming both the Lipper flexible portfolio peer group median return of
9.85 percent and the S&P 500 Index return of 17.72 percent. The benchmark S&P
500 Index is comprised of large-cap equity stocks, reflecting the main portion
of the Fund's investments. However, the Fund also invests significant assets in
international equities and fixed income securities, and for that reason we think
it's useful to mention the returns for those two categories as well. Fixed
income securities as represented by the Lehman Intermediate Government/Corporate
Index returned 3.47 percent and international equities as represented by the
Morgan Stanley Capital International Europe Australia and Far East Index
returned 13.74 percent for the same period.

Q: WHAT AFFECTED THE MARKETS AND THEREFORE THE FUND DURING THE PAST SIX MONTHS?

A: The Asian crisis has led to favorable and unfavorable developments in the
United States. On the positive side the dollar is strong, and energy prices and
inflation are low. On the negative side, the U.S. trade balance has deteriorated
as exports diminished and imports remained firm. The combined result is that the
U.S. consumer is benefiting from solid economic growth, with employment gains
and real wages showing the sharpest increase in over 20 years. The Fund
benefited from strong consumer spending, and retail stock holdings Wal-Mart
Stores and Home Depot, (1.5 percent and 1.5 percent of total net assets,
respectively) were among the best-performing holdings.

Q: DO YOU EXPECT CURRENT ECONOMIC CONDITIONS TO CONTINUE?

A: We anticipate reduced U.S. corporate profits and profit margins over the next
several quarters. Factors we believe will influence weaker pricing power
include, increased foreign competition, reduced exports and increased salary
payments. We have been investing in companies that we believe stand to counter
these trends, such as drug companies experiencing new product cycles and
financial companies benefiting from lower long-term interest rates. Holdings in
these sectors boosted the Fund's performance during the period. Drug stocks that
performed well were Pfizer, Eli Lilly, American Home Products and Bristol-Myers
Squibb (1.1 percent, 1.1 percent, 1.1 percent and 1.2 percent of total net
assets, respectively).

Q: WHAT HURT PERFORMANCE?

   A: Our investment in REIT stocks has been disappointing. Investors have been
steering away from these stocks this year even though earnings have been solid
and dividend yields high because of concerns over legislation, new issue supply
and new construction. However, we plan to maintain our exposure to REIT stocks,
because we believe they are excellent value investments that possess strong
upside potential.

Another drag on performance came from Cendant; previously one of the Fund's
largest holdings. This stock dropped significantly after accounting
irregularities were exposed (0.9 percent of total net assets).

Latin American holdings that supported the Fund's performance in the first
quarter of 1998 restricted performance in the recent quarter, as these stocks
reacted more than we anticipated to a second round of Asian turmoil.

PORTFOLIO MANAGER'S DISCUSSION (continued)
Stein Roe Balanced Fund, Variable Series
- --------------------------------------------------------------------------------

We also were disappointed by the performance of our holdings in the energy
sector. We reduced our exposure to this sector early in the first quarter of
1998 as oil prices began to deteriorate.

Early in the second quarter, we reduced our equity exposure modestly by selling
investments which were not performing in line with our expectations. We then
redeployed the cash toward the end of the period as conditions were falling into
place for renewed stock market improvement.

Q: WHAT DID YOU PURCHASE?

A: We added several names to the portfolio to increase the Fund's industry
diversification. They include WorldCom in the telecommunications area, Travelers
Group in the financial services area and TCI Group in the media area (1.3
percent, 1.1 percent and 0.6 percent of total net assets, respectively).

Q: HOW DID THE PORTFOLIO'S FIXED INCOME PORTION PERFORM?

A: Our longer-duration strategy in fixed income holdings benefited the Fund's
performance, as interest rates were modestly lower during the period. We expect
the Federal Reserve Board to maintain the current interest rate environment for
the foreseeable future. Therefore, we continue to hold a full, high-quality
position in fixed income. We are now in the environment of a federal budget
surplus and anticipate that the government will use some of the budget surplus
this year to pay down debt. This event would provide support for the fixed
income market. Also, in anticipation of slowing growth in the economy, we
anticipate that the yields on long-term bonds will ease further by year-end.

Q: WHAT'S YOUR OUTLOOK?

A: We are somewhat cautious about the stock market's ability to maintain its
current strength because we think the valuations of many stocks are high. We
continue to project moderate U.S. economic activity with real growth of 2 to 2
1/2 percent through the end of 1999. In this environment, inflation should
remain muted and interest rates may drift lower. Selectivity in purchasing will
become increasingly important, as the overall stock market in coming months
likely will be digesting the gains of the past few years.

PORTFOLIO MANAGER'S DISCUSSION
Stein Roe Mortgage Securities Fund, Variable Series
- --------------------------------------------------------------------------------



Q: HOW DID THE FUND PERFORM?

A: For the six-month period ended June 30, 1998, Mortgage Securities Fund,
Variable Series, returned 3.43 percent, beating the Lipper U.S. mortgage fund
peer group median and the Lehman Mortgage Backed Securities Fixed Rate Index
returns of 3.42 percent and 3.38 percent, respectively.

Q: WHAT TRANSPIRED IN THE MORTGAGE SECURITIES MARKET OVER THE PAST SIX MONTHS?

A: During the first quarter, the differences, or spreads, between yields on
mortgage securities and U.S. Treasury securities widened, an event that occurred
in the corporate and other bond markets as well. Corporate bond yields widened
in reaction to the Asian financial crisis and fears of a slowdown in U.S.
economic activity.

In the second quarter, falling bond yields dropped home-mortgage rates to their
lowest levels in five years. However, what is great news to homeowners -- the
opportunity to refinance their mortgage -- is often a negative to investors in
mortgage-backed securities. Prices of these bonds, which represent an ownership
interest in mortgage loans made by financial institutions, usually lag behind
Treasury bonds as interest rates fall, and that has been the case throughout
much of the second quarter. From a historical perspective, however, the decline
in yields was relatively benign and much smaller than the expected interest rate
move priced into the yield spread between mortgage-backed securities and
Treasuries. This enabled mortgage returns to perform reasonably well in a
difficult environment of spread widening and faster-than-expected prepayments.

While concerns regarding Asia and its impact on the U.S. economy may persist for
some time, we believe this widening of spreads has made both the mortgage and
corporate sectors attractive. This, together with an outlook of subdued interest
rate volatility, bodes well for mortgage securities in the period ahead.

Q: WHAT STRATEGIES AIDED THE FUND'S PERFORMANCE?

A: One strategy that supported our outperformance was our longer duration. We've
been maintaining it at three and a quarter to three and one half years, and this
relatively longer stance helped performance as interest rates dropped and
longer-term securities rose in market value.

Another factor that supported the Fund's performance was the high quality of our
holdings. Mortgage funds that invest more aggressively, such as hedge funds or
real estate investment trusts (REITs), use leverage or borrowed money to
increase their profits. While this tactic can be successful, it also can falter
when mortgage prepayments do not conform to expectations. Recently, when
interest rates fell, prepayment rates on higher-coupon mortgages accelerated
beyond market expectations because of a stronger housing market and improvements
in refinancing technology. Struggling hedge funds and REITs were forced to dump
their leveraged positions in interest-only mortgage securities, which are
extremely sensitive to accelerating prepayment trends. This depressed prices of
interest-only securities by 20 percent. While press reports regarding the
condition of the mortgage market have been alarming, they have overstated the
extent to which problems facing the interest-only sector have spilled over to
the overall market for mortgage-backed issues. Those mortgage funds that have
invested in the riskiest mortgage securities suffer the most. While we held
positions in seasoned premium mortgages that prepaid faster than expected, our
position in interest-only securities is small. This conservative approach has
stood the test of time and is another reason we outperformed our peer group.

PORTFOLIO MANAGER'S DISCUSSION (continued)
Stein Roe Mortgage Securities Fund, Variable Series
- --------------------------------------------------------------------------------

Q: WHERE ELSE DID YOU FOCUS YOUR INVESTMENTS?

A: We continue to maintain a positive outlook regarding our exposure to
subordinate home equity and home improvement loans, even though they have
underperformed since our initial purchase during late 1997. These high-quality
holdings possess substantial credit protection to adequately handle adverse
delinquency and loss environments. They are also currently priced better than
comparably-rated corporate alternatives. We expect spreads in this sector to
narrow over the coming 12-18 months as prepayments become more common.

Q: ARE YOU STILL UNDERWEIGHT MORTGAGE-BACKED SECURITIES?

A: The portfolio continues to hold a slightly lower-than-normal weighting of
83.8 percent of total net assets in mortgage securities. This can be compared to
a typical historical weighting of 85 percent to 90 percent of total net assets.

However, we did increase our exposure during the period, up from 72.3 percent at
the beginning of the year, by purchasing discount government mortgage bonds that
we believe to be relatively insensitive to prepayment risk. At the end of the
year, we took advantage of supply pressures and reinvested principal prepayments
into home-equity loans with non-accelerating senior (NAS) structures. These
securities offer yield spreads up to one third of a percent higher than other
mortgage alternatives such as agency collateralized mortgage obligations (CMOs).
Home equity loan NAS investments are attractive because they are less sensitive
to prepayment risk and contain structural protection whereby principal cash
flows are "locked out" from prepayments for the first three years of the
transaction. This combination of refinancing and structural protection is
expected to lead to total rates of return greater than the initial yield
advantage versus agency CMOs. Our outlook for the sector has improved slightly,
and we plan to increase the percentage of mortgage holdings when opportunities
arise.

We plan to maintain our positions in Treasury securities and corporate bonds. If
interest rates decline, Treasury securities should outperform mortgage-backed
securities over the near term. The corporate bonds we hold are all
investment-grade issues rated `A' or higher. We believe the specific corporate
issues we own offer income and total return potential comparable to or better
than mortgage-backed securities, but without the refinancing risk.

Q: WHAT'S YOUR OUTLOOK?

A: Compared to historical experience, interest rate volatility has been very low
over the past eighteen-month period. A combination of moderate economic growth
and low inflation is expected to keep existing Federal Reserve interest rate
policy on hold. We therefore continue to believe that interest rate volatility
will remain subdued. This, coupled with wider yield spreads, should provide a
favorable environment going forward for mortgage-backed securities.

PORTFOLIO MANAGER'S DISCUSSION
Stein Roe Money Market Fund, Variable Series
- --------------------------------------------------------------------------------

Q: HOW DID THE FUND PERFORM?

A: The Stein Roe Money Market Fund, Variable Series, performed in line with the
peer group and the Index for the six-month period ended June 30, 1998. The total
return for the Fund was 2.55 percent, versus 2.53 percent for the 90-day
Treasury Bill Index and 2.48 percent for the Lipper money market fund peer
group. The Fund's average total return for the one-year, five-year and since
inception periods ended June 30, 1998, were 3.85 percent, 4.39 percent and 5.17
percent, respectively.

Q: WHAT AFFECTED THE CHANGE IN THE FUND'S YIELD?

A: When year-end financing pressures wore off, the inflated rates being offered
by money market securities lowered, as we expected. As a result, the Fund's
seven-day yield decreased from 5.32 percent at Dec. 31, 1997 to 5.05 percent at
June 30, 1998. With the exception of the year-end peak keeping yields high at
the beginning of the year, the yield curve remained flat. We lengthened the
Fund's weighted average maturity to approximately 33.1 days (neutral maturity)
because we don't expect the Federal Reserve to increase interest rates anytime
soon.

Q: DID THE FUND'S STRUCTURE CHANGE THROUGHOUT THE PERIOD?

A: We've been moving into domestic commercial paper throughout 1998, as
reflected in the Fund's holdings. We've limited our Japanese positions in
letters of credit commercial paper and Yankee CDs because we believe it was in
the Fund's best interest to limit exposure to that area. However, our position
in Yankee CDs increased because we believe securities backed by Canadian and
European banks are still attractive purchases. During the first quarter of the
fiscal year, our holdings in federal agency securities matured. Although we
would have liked to maintain the Fund's exposure to that sector, it was too
expensive to make attractive new purchases. We wanted to add to our position in
variable rate note securities as a hedge against interest rate fluctuations, but
we had a hard time finding any of these "floaters" throughout the year, as they
were not offered at attractive prices. We instead replaced our floaters and a
maturing federal agency note with a one-year Yankee CD from Canada (4.0 percent
of total net assets) and some regular commercial paper.

Q: BASED ON THE RISKINESS OF INVESTING IN ASIAN MARKETS, DOES THE FUND HAVE ANY
EXPOSURE THERE?

A: The Fund did hold Japanese letter of credit commercial paper. We often invest
in Japanese-backed issues when they are offering attractive yields. However,
during this period, when the Fund's Japanese holdings matured we did not replace
them because we believe there is presently too much risk in having exposure to
that area. We invested the proceeds in regular commercial paper and a Yankee CD.
The Fund's average yield decreased slightly as a result of this move.

Q: WAS THERE ANY CHANGE IN INTEREST RATE ACTIVITY THROUGHOUT THE SIX-MONTH
PERIOD?

A: We saw a spark in the shortest-term rates near the end of the six-month
period, as the date of the Federal Open Market Committee (FOMC) meeting
approached and created speculation about the direction of interest rates.
However, long-term interest rates remained unchanged throughout the entire
period. There was a stated bias toward tightening rates at the May meeting, but
rates remained unchanged, likely due to problems in Asia. In the days since that
meeting, the situation in Asia has become worse. Because of that, we believe
interest rates will remain unchanged for at least a few more months.

Q: ALTHOUGH A FLAT YIELD CURVE RESTRICTS SOME VALUE TRADING, ISN'T STABILITY
GOOD FOR A MONEY MARKET FUND?

A: Yes. In circumstances like we've seen this year, when the stock and bond
markets are high and both markets are volatile, many investors shift assets into
money market funds for stability. Investors also use money market funds as the
cash basis of their investment portfolio. While money market funds have not
returned resounding rates, given the current interest rate environment, we
believe they have provided decent returns for short-term, high-liquidity
investing.

Q: WHAT'S YOUR INVESTMENT STRATEGY FOR THE REMAINDER OF 1998?

A: Part of our strategy will depend on what the Federal Reserve does with
interest rates. Until investors begin to believe that there will be a change in
interest rates, yields will remain flat. Factors that may push rates up include
a recovery in Asia, increased inflation in the United States or
stronger-than-expected economic growth.

We plan to lengthen the Fund's duration when we see the potential for profiting
from this move. We'll remain cautious in our maturity range, too. Without
finding value in the Japanese market, we plan to remain heavily invested in U.S.
commercial paper. We will also continue to invest in letter of credit commercial
paper and European and Canadian Yankee CDs when they offer good relative values.

                          NOTES TO FINANCIAL STATEMENTS
NOTE 1. ORGANIZATION AND ACCOUNTING POLICIES

SteinRoe Variable Investment Trust (the "Trust"), an open-end man age ment
investment company, was organized as a Massachusetts business trust on June 9,
1987. At June 30, 1998 the Trust consisted of five diversified Funds with
differing investment objectives, policies and restrictions (individually
referred to as a "Fund," or collectively referred to as the "Funds"):

STEIN ROE SPECIAL VENTURE FUND, VARIABLE SERIES--seeks capital growth by
investing in equity securities.

STEIN ROE GROWTH STOCK FUND, VARIABLE SERIES--seeks long-term growth of capital
by investing 65 percent of total assets in growth companies.

STEIN ROE BALANCED FUND, VARIABLE SERIES--seeks high total investment return by
investing in equity and debt securities.

STEIN ROE MORTGAGE SECURITIES FUND, VARIABLE SERIES--seeks highest possible
level of current income by investing at least 65 percent of total assets in
mortgage pass-through certificates.

STEIN ROE MONEY MARKET FUND, VARIABLE SERIES--seeks high current income while
emphasizing capital preservation from investment in short-term money market
instruments.

Shares of the Trust are available and are being marketed exclusively as a pooled
funding vehicle for variable annuity contracts ("VA contracts") and variable
life insurance policies ("VLI policies") of various affiliated insurance
companies and, in the case of Stein Roe Special Venture Fund, Variable Series,
also of Transamerica Life Companies, Great-West Life & Annuity Insurance Company
and Providian Life & Health Insurance Company. Stein Roe & Farnham, Incorporated
(the "Adviser") provides investment advisory services to the Funds as well as
management and administrative services. SteinRoe Services, Inc. provides
transfer agent services. Keyport Financial Services Corp., a subsidiary of
Keyport Life Insurance Company ("Keyport"), serves as the underwriter of the
Trust. Keyport, the Adviser and the Transfer Agent are direct subsidiaries of
Liberty Financial Companies, Inc. At June 30, 1998, various affiliated insurance
companies of Liberty Financial Companies Inc. owned 100 percent of the
outstanding shares of all Funds, except for Stein Roe Special Venture Fund,
Variable Series, of which Liberty Financial Companies Inc. affiliates owned 93.0
percent, Great-West Life & Annuity Insurance Company owned 5.3 percent,
Transamerica Life Companies owned 1.6 percent, and Providian Life & Health
Insurance Company owned 0.1 percent.

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements. The policies are in
conformity with generally accepted accounting principles. The preparation of
financial statements in conformity with generally accepted accounting principles
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts of
increases and decreases in net assets from operations during the reporting
period. Actual results could differ from those estimates.

Certain prior-year amounts have been reclassified to conform to current-year
presentation.

VALUATION OF INVESTMENTS--Portfolio securities listed on domestic exchanges and
over-the-counter securities quoted on the Nasdaq system are valued on the basis
of the last sale on the date as of which the valuation is made, or, lacking any
sales, at the current bid prices. Over-the-counter securities not quoted on the
Nasdaq system are valued at the latest bid quotation. Foreign security
valuations are generally based upon market quotations which, depending upon
local convention or regulation, may be last sale price, last bid or asked price,
or the mean between last bid and asked prices as of, in each case, the close of
the appropriate exchange or other designated time. Long-term debt securities are
valued on the basis of dealer-supplied quotations or valuations furnished by a
pricing service. Securities for which reliable quotations are not readily
available are valued at fair value, as determined in good faith and pursuant to
procedures established by the Trustees. Short-term securities with remaining
maturities of 60 days or less are valued at amortized cost unless the Trustees
determine this does not represent fair value. Stein Roe Money Market Fund,
Variable Series, values investments utilizing the amortized cost valuation
technique permitted in accordance with Rule 2a-7 under the Investment Company
Act of 1940, which requires the Fund to comply with certain conditions. This
technique involves valuing a portfolio security initially at its cost and,
thereafter, assuming a constant amortization to maturity of any discount or
premium.

FEDERAL INCOME TAXES--The Funds now qualify and intend to continue qualifying as
"regulated investment companies" and, as such (and by complying with the
applicable provisions of the Internal Revenue Code), will not be subject to
federal income tax on taxable income (including realized capital gains)
distributed to shareholders.

FOREIGN CURRENCY TRANSACTIONS--Certain of the Funds have entered into foreign
exchange contracts for the settlement of purchases and sales of securities
denominated in a foreign currency to reduce the risk to the Funds from adverse
changes in the relationship between the U.S. dollar and the foreign currency.
The face or contract amount in U.S. dollars reflects the total exposure the Fund
has in that particular currency contract. In the event that the counterparty in
the foreign exchange contract fails to meet the terms of the contract, the Fund
could be exposed to the effects of changes in the relationship between the U.S.
dollar and the foreign currency.

<PAGE>

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)

INVESTMENT TRANSACTIONS--The Funds may purchase or sell securities on a
when-issued, delayed delivery or forward commitment basis. Payment and delivery
may take place a month or more after the date of the transaction. The price of
the underlying securities and the date when the securities will be delivered and
paid for are fixed at the time the transaction is negotiated. Stein Roe Balanced
Fund, Variable Series, and Stein Roe Mortgage Securities Fund, Variable Series,
may also enter into dollar roll transactions. In a dollar roll transaction, the
Fund sells securities for delivery in the current month and simultaneously
contracts to repurchase, typically in 30 days to 60 days, substantially similar
securities at an agreed upon price and date. These transactions may increase the
risk if the other party to the transaction fails to deliver and causes the Fund
to subsequently invest at less advantageous yields. The Funds identify
securities as segregated in their custodial records with a value at least equal
to the amount of the purchase commitment.

INVESTMENT IN REPURCHASE AGREEMENTS--Each Fund may enter into repurchase
agreements with banks, broker-dealer firms and other recognized financial
institutions whereby such institutions sell an instrument to the Fund, and the
seller agrees, at the time of the sale, to repurchase that instrument at a
specified time and price. The Funds require the seller of the instrument to
maintain on deposit with the Funds' custodian bank or in the Federal Reserve
Book-Entry System securities in an amount at all times equal to or in excess of
the value of the repurchase agreement plus accrued interest. In the event the
seller of the instrument defaults on the repurchase obligation, a Fund could
receive less than the repurchase price on the sale of the securities to another
party or could be subject to delays in selling the securities.

OTHER--Security transactions are accounted for on trade date. Interest income is
recorded on the accrual basis. Discounts on debt securities are amortized in
accordance with Internal Revenue Code requirements. Dividend income and
distributions to shareholders are recorded on the ex-dividend date. Net realized
and unrealized gains (losses) on foreign currency transactions include the
fluctuation in exchange rates on gains and losses between trade and settlement
dates on security transactions, gains and losses arising from the disposition of
foreign currency, and currency gains and losses between the accrual and payment
dates on dividend and interest income and foreign withholding taxes. The Funds
do not isolate that portion of the results of operations resulting from changes
in foreign exchange rates on investment from the fluctuations arising from
changes in market prices of securities held. Such fluctuations are included with
the net realized and unrealized gain or loss from investments.

Unrealized appreciation and depreciation and realized gains and losses may
differ between financial statements and tax earnings due to deferred losses from
wash sales and certain other transactions.

NOTE 2. FUND SHARE TRANSACTIONS

Each Fund's capitalization consists of an unlimited number of shares of
beneficial interest without par value that represent a separate series of the
Trust. Each share of a Fund represents an equal proportionate beneficial
interest in that Fund and, when issued and outstanding, is fully paid and
nonassessable. Shareholders would be entitled to share proportionally in the net
assets of a Fund available for distribution to shareholders upon liquidation of
a Fund.

NOTE 3. SECURITY TRANSACTIONS

Realized gains and losses are computed on the identified cost basis for both
financial reporting and federal income tax purposes. At December 31, 1997, Stein
Roe Mortgage Securities Fund, Variable Series, had a capital loss carryforward
of $3,026,065, which will expire between 2002 and 2005, if not utilized. The
cost of investments purchased and proceeds from investments sold, excluding
short-term investments, for the six months ended June 30, 1998, for the Funds,
excluding Stein Roe Money Market Fund, Variable Series, were as follows:

                 SPECIAL          GROWTH         BALANCED          MORTGAGE

NOTE 4. DISTRIBUTIONS TO SHAREHOLDERS

The Funds, with the exception of the Stein Roe Money Market Fund, Variable
Series, intend to distribute as dividends or capital gain distributions, at
least annually, substantially all of their net investment income and net gains
realized from the sale of portfolio securities. All dividends and distributions
are reinvested in additional shares of the Funds. Stein Roe Money Market Fund,
Variable Series, declares dividends daily and reinvests all dividends declared
monthly in additional shares at net asset value. Income and capital gains
distributions are determined in accordance with federal income tax regulations,
which may differ from generally accepted accounting principles, primarily
relating to foreign currency gains or losses and book-tax timing differences.
