         CHAIRMAN'S LETTER

Dear fellow shareholders:

The Federal Reserve raised the federal funds rate by +0.50% to 6.50% on May
16th, 2000. This increase was the Fed's sixth in a series of tightening moves
totaling +1.75% that began on June 30, 1999 in its continued efforts to moderate
strong economic growth. The Fed has kept short-term interest rates unchanged
since mid-May, but has maintained its bias against inflation since early
February. Fed policy has caused money market yields to trend higher. However,
longer-term bond yields have declined as the U.S. Treasury has purchased
longer-maturity bonds to reduce debt, contributing to strongly positive returns
for bond investors year-to-date.

ECONOMIC OVERVIEW

Economic activity has moderated from the torrid pace of the first half of the
year, but figures still suggest solid growth. The first estimate of real GDP
growth for 3Q00 was reported at a +2.7% annualized rate, compared with +5.6% in
2Q00 and +4.8% in 1Q00. Real final sales grew at +2.7% in the third quarter,
compared with +3.9% in the second quarter and +6.7% in the first quarter.
Consumer spending, which accounts for two-thirds of GDP, accelerated to +4.5% in
the third quarter from +3.1% in the second quarter, but was still much less than
the +7.6% rate in 1Q00. The personal savings rate fell to an all time low of
-0.2%, compared to +0.3% last quarter. However, the savings rate is distorted as
it includes taxes paid on capital gains as spending, and does not include the
realized gains as income.

Other sectors of the economy continue to show slowing momentum. Business
investment, particularly spending on technology, remains positive, but has
moderated considerably since the beginning of the year from +21.0% in 1Q00 to
+14.6% in 2Q00 and +6.9% in 3Q00. Third quarter growth was also offset by a
contraction in government spending, which fell -3.6%, led by a -10.1% drop in
federal spending, after swinging from -1.1% in 1Q00 to +4.8% in 2Q00 (with
federal spending rising +17.2%). In addition, residential investment contracted
-9.2%, compared with +1.3% in the second quarter and +3.2% in the first quarter,
reflecting a continued cooling in activity from peak levels earlier in the year.
International trade remained a drag on growth in the third quarter, but export
growth in the third quarter outpaced import growth for the first time since
4Q98. Other economic measures also confirm moderation in economic activity.
September industrial production rose +0.2%, compared with +0.3% in August and
+0.4% in July. In addition, the National Association of Purchasing Management's
(NAPM) composite index remains below the neutral 50 level. We believe that real
GDP should continue at a more sustainable pace of +3.0% to +3.5% into the year
2001.

Producer and consumer price inflation appear under control, but we expect
inflation to trend higher over the next few quarters, primarily due to higher
energy costs and a leveling-off in record-setting productivity growth. Though
consumers are seeing higher gas and electricity bills, prices of goods have been
remarkably unaffected as manufacturers have not been able to pass on higher
energy costs and, instead, are finding other places to cut costs. We believe
inflation will peak at around +3.5% and then begin to abate by spring 2001. The
unemployment rate remains at a record low 3.9%, and we are monitoring labor cost
trends closely. Other inflation indicators, including the GDP deflator, show
that inflation remains contained.

The weak euro and higher energy prices may actually aid the U.S. economy in
achieving a soft landing by slowing corporate profit growth. The euro has
continued to hit new lows in recent weeks, despite joint intervention from
central banks in late September. The U.S. dollar continues to strengthen and is
+8.4% higher on a trade-weighted basis than a year ago. While the weak euro
could make U.S. exports less trade-competitive, a strong U.S. currency is
anti-inflationary and attracts foreign capital.

Much of future fiscal policy depends on the outcome of the November elections.
The presidential race continues to tighten, resulting in the closest race since
1980 and

perhaps 1960. Republicans are likely to lose several seats in the House and
Senate, but retain majorities. The fiscal 2000 federal budget surplus of $237
billion was nearly double last year's $124.4 billion. The ability to sustain
surpluses in the future depends on a return to fiscal discipline, which has
lapsed in the past two years, and a continued healthy economy.

STRATEGY SUMMARY

The Federal Reserve left the federal funds rate unchanged at 6.50% at its
meeting on October 3rd. We believe that the Fed is done tightening and that the
series of six rate hikes made between June 1999 and May 2000 will be sufficient
to achieve the Fed's desired "soft landing" and to keep inflation in check. The
weak euro and higher energy prices are also expected to help moderate growth.

Yields on 30-year Treasury bonds, which rallied earlier in the year sparked by
the Treasury Department's decision to repurchase long-term Treasury debt, have
remained in a narrow range in recent months. Short-to-intermediate maturity
Treasury yields have fallen 20-50 basis points to year-to-date lows as signs of
economic slowing have emerged, causing the yield curve to become less inverted
in recent months. Yield curves for other taxable sectors remain more positively
sloped. Corporate bond yields have been relatively high since January as heavy
issuance and concerns over a slower economy have widened the incremental yields
demanded by investors from that sector. The best-performing sectors in recent
months have included asset-backeds and mortgages, which have benefited from
their high quality, relatively short durations and more than 1.0% yield
advantage over Treasuries. Our taxable bond funds continue to underweight
Treasuries, yet maintain their AAA average quality rating. Portfolio durations
are near those of their respective benchmarks and are positioned to benefit from
a steepening yield curve.

Municipal yields declined to 12-month lows in August, benefiting from lower
issuance this year and from strong demand from direct individual purchasers of
bonds. Municipal indices have provided competitive returns relative to most
taxable bond indices year-to-date. The municipal yield curve remains positively
sloped, although it has flattened in shape since January. Municipals continue to
appear cheaply valued when compared to Treasuries, but look overvalued when
compared to agencies and corporates. As we anticipated, hospital bonds are
providing one of the strongest returns among revenue bond sectors this year,
recouping some of last year's underperformance. Hospitals are seeing some
improvement from operating margin pressures last year, and our focus remains on
issuers that are sole community providers, are financially flexible and have
strong managements. Housing has lagged due to its more stable price
characteristics. Yields offered by lower-rated investment grade municipals
remain attractive, as quality spreads are still wide, and we continue to monitor
credits closely. Municipals in the 8-15 year maturity range continue to offer
the most attractive risk/reward opportunities. We believe municipals are an
attractive complement to other asset classes in the economic environment we
foresee ahead.

We believe our continued focus on high current income and relative stability of
principal value will help provide attractive incremental returns for
shareholders over the longer term. We appreciate your continued interest in the
Sit Mutual Funds and look forward to helping you achieve your long-term
investment goals.

With best wishes,

/s/ Eugene C. Sit

PERFORMANCE SUMMARY - BOND FUNDS

   The Federal Reserve raised the federal funds rate by +0.50% to 6.50% on May
16, 2000 in its continued efforts to moderate strong economic growth. This
increase was the Fed's sixth in a series of tightening moves totaling +1.75%
that began on June 30, 1999. The Fed has kept short-term interest rates
unchanged since mid-May, but has maintained its bias against "inflation" since
early February. Money market yields continued to trend higher, with 3-month
T-bill yields increasing from 5.86% to 6.22% during the six-month period ended
September 29, 2000.
   Treasury bond yields peaked in mid-May, giving back some of the rally that
was initially sparked by the Treasury Department's decision to reduce debt by
purchasing long-term Treasuries. The 30-year Treasury yield has remained in a
relatively narrow range and ended the six month period just +0.04% higher at
5.88%. As signs of slower economic growth have become evident in recent months,
short-to-intermediate maturity Treasury yields have fallen 20-50 basis points to
year-to-date lows, causing the yield curve to become less inverted. Yield curves
for other sectors of the taxable bond market remain more positively sloped.
Intermediate duration sectors outperformed during the period. Mortgages, with
their yield advantage, posted the highest returns, and asset-backeds and
agencies also performed well. Corporate bond yields have remained relatively
high since the beginning of the year as heavy issuance and concerns over a
slower economy have widened the incremental yields demanded by investors from
that sector, causing it to underperform.
   Municipal yields declined and the yield curve remains positively sloped. The
yield on the Bond Buyer 40-Bond Index fell -0.15% during the period to 5.82%.
Municipals benefited from lower issuance this year and from strong demand from
direct individual purchasers of bonds. Municipal indices underperformed taxable
indices due to their longer durations and their lower (before tax) income
return. Among revenue bond sectors, hospitals have posted the strongest returns,
recouping some of last year's underperformance, while housing lagged due to its
more stable price characteristics. Municipals continue to appear cheaply valued
when compared to Treasuries, but look overvalued when compared to agencies and
corporates. Yields offered by lower-rated investment grade municipals remain
attractive, however, as quality spreads are still wide. Municipals in the 8-15
year maturity range continue to offer the most attractive risk/reward
opportunities.

[PHOTO]  SIT MONEY MARKET FUND
         SIX MONTHS ENDED SEPTEMBER 30, 2000
         -----------------------------------------------------------------------

   The Sit Money Market Fund provided investors with a +1.56% return for the
three months ended September 30, 2000, compared to a +1.46% average return for
the Lipper Analytical Services, Money Market Fund universe. The Fund's
performance ranked 70th of 376 funds in its Lipper peer group category for the
third quarter of 2000. For the one year, three year, five year and since
inception periods ended September 30, 2000, the Fund's performance ranked 84th
of 362 funds, 72nd of 289 funds, 65th of 249 funds and 42nd of 185 funds,
respectively, in its Lipper peer group. As of September 30, 2000, the Fund's
7-day compound yield was 6.32% and its average maturity was 27 days, compared to
6.35% and 29 days, respectively, at June 30, 2000.
   The Federal Reserve Board held the federal funds rate during the past quarter
at 6.50%, in response to visibly slowing growth in the economy, commodity price
inflation and tightness in labor markets. Three-month Treasury bill yields rose
over the past quarter, ranging from 5.85% on June 30th to 6.32% by late August,
finishing at 6.19% on September 30th. Current yield levels imply that the market
is not expecting additional tightening by the Fed in the fourth quarter of 2000.
Indeed, many investors now feel the Fed is done with its tightening for this
cycle. Given the expected slowdown in the economy, we also believe the Fed is
done tightening. The Fund anticipates maintaining an average maturity near 30
days over the near term.
   The Fund has produced competitive returns by focusing on credit research,
optimizing average maturity and avoiding the use of risky derivatives. We intend
to continue these conservative policies in the future. As domestic economic
activity slows from a very strong level, we do not foresee a significant impact
on the short-term creditworthiness of top tier commercial paper issuers in
general. However, certain issuers may experience some liquidity challenges over
the coming months and we will increase our vigilance as market conditions
warrant. The Fund continues to diversify its core holdings and its industry
exposure. In the months ahead, we hope to add top tier credits in the financial
services and consumer non-durable industries to our list of permissible
holdings.


                        INVESTMENT OBJECTIVE AND STRATEGY

   The objective of the Fund is to achieve maximum current income to the extent
consistent with the preservation of capital and maintenance of liquidity. The
Fund pursues this objective by investing in short-term debt instruments which
mature in 397 days or less and by maintaining a dollar-weighted portfolio
maturity of 90 days or less.

   An investment in the Fund is neither insured nor guaranteed by the U.S.
government and there can be no assurance that the Fund will be able to maintain
a stable net asset value of $1.00 per share.

[PHOTO]  SIT U.S. GOVERNMENT SECURITIES FUND
         SIX MONTHS ENDED SEPTEMBER 30, 2000
         -----------------------------------------------------------------------
         MICHAEL C. BRILLEY, SENIOR PORTFOLIO MANAGER
         BRYCE A. DOTY, CFA, SENIOR PORTFOLIO MANAGER

   The Sit U.S. Government Securities Fund provided investors with a +3.9%
return for the 6 months ended September 30, 2000, compared to a +4.5% return of
the Lehman Intermediate Government Bond Index. For the 12 months ending
September 30, the Fund's total return was +6.0%, versus +6.1% for the Lipper
U.S. Government Fund Average, and +6.2% for the Lehman Index. The Fund holds a
5-star overall rating by Morningstar in the taxable bond category which includes
1,741 funds as of September 30, 2000.
   The U.S. Treasury yield curve steepened significantly during the third
quarter after changing very little during the second quarter. Shorter maturity
Treasuries declined 20-40 basis points in yield, while the 30-year Treasury
yield ended the quarter essentially unchanged. This yield curve shift was the
result of the market's perception of a slowing economy and an approaching end to
the Federal Reserve's recent series of interest rate hikes. The Fund's U.S.
Treasury holdings provided the highest returns over the last six months as
Treasury buybacks by the government and investor demand for high quality
securities drove up prices. However, mortgage securities performed as well as
Treasuries during the third quarter.
   Investment activity for the period included slightly increasing the portfolio
weighting of collateralized mortgage obligations (CMO's) to obtain high yields
as well as provide protection against potential faster prepayments of the
underlying mortgages. Treasury Inflation Protected Securities (TIPS) were also
purchased during the period to take advantage of monthly spikes in inflation
rates. The principal of these securities increases at the rate of CPI while also
paying a fixed coupon. The TIPS were sold late in the quarter as the monthly
inflation rates declined substantially. As oil prices remain volatile, monthly
inflation will likely fluctuate and we expect future investment opportunities in
TIPS on a periodic basis.
   Looking ahead, we expect a slight decrease in short-term rates and little
change in longer-term rates due to a slowing economy and moderate inflation. As
the Federal Reserve contemplates the possibility of lowering short-term rates,
as opposed to the recent series of increases, we expect government securities
that offer high levels of current income, such as mortgage pass-throughs and
CMO's, to provide the most attractive total return opportunities.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The objective of the U.S. Government Securities Fund is to provide high
current income and safety of principal, which it seeks to attain by investing
solely in debt obligations issues, guaranteed or insured by the U.S. government
or its agencies or its instrumentalities.
     Agency mortgage securities and U.S. Treasury securities will be the
principal holdings in the Fund. The mortgage securities that the Fund will
purchase consist of pass-through securities including those issued by Government
National Mortgage Association (GNMA), Federal National Mortgage Asociation
(FNMA), and Federal Home Loan Mortgage Corporation (FHLMC).


                                PORTFOLIO SUMMARY

                Net Asset Value   9/30/00:    $10.29 Per Share
                                  3/31/00:    $10.22 Per Share
                         Total Net Assets:   $139.8 Million
                         30-day SEC Yield:      6.21%
               12-Month Distribution Rate:      6.14%
                         Average Maturity:     15.5 Years
                       Effective Duration:      3.4 Years(2)

(2) Effective duration is a measure which reflects estimated price sensitivity
to a given change in interest rates. For example, for an interest rate change of
1.0%, a portfolio with a duration of 5 years would be expected to experience a
price change of 5%. Effective duration is based on current interest rates and
the Adviser's assumptions regarding the expected average life of individual
securities held in the portfolio.

[PHOTO]  SIT TAX-FREE INCOME FUND
         SIX MONTHS ENDED SEPTEMBER 30, 2000
         -----------------------------------------------------------------------
         MICHAEL C. BRILLEY, SENIOR PORTFOLIO MANAGER
         DEBRA A. SIT, CFA, SENIOR PORTFOLIO MANAGER

   Municipal bond prices rose during the six month period after bottoming in
mid-May. The Fund's price per share rose from $9.73 to $9.81 during the period
and ranged from a low of $9.55 in mid-May to a high of $9.87 in early September.
The Fund benefited from declining yields since mid-May and from stabilizing
yields in the health care sector, and provided a return of +3.56% for the six
month period ended September 29, 2000, compared to +3.58% for the Lehman 5-year
Municipal Index. The Fund's 30-day SEC yield rose from 5.42% to 5.71% during the
period and its 12-month distribution rate increased from 5.19% to 5.40%,
contrary to the general declining trend of bond yields.
   We continue to look for opportunities to increase the yield in the portfolio,
as incremental credit spreads remain wide. Purchases were made in the hospital
and other revenue sectors, which increased from 21.5% to 24.1% and from 6.0% to
7.7%, respectively. Multifamily housing bonds increased from 37.5% to 39.0%,
despite net sales. Cash decreased from 10.6% to 3.3% as assets declined from
$172.9 million to $163.4 million. Securities rated A or better decreased from
52.1% to 48.6% while non-rated holdings increased from 40.0% to 42.7%. We intend
to keep non-rated holdings around their current weighting to ensure portfolio
liquidity. The Fund's average maturity extended from 16.6 years to 17.3 years
due to the decrease in cash. Nonetheless, the Fund's implied duration, which is
based on historical price changes, increased from 7.1 years to 8.2 years,
reflecting the increased price sensitivity of the Fund's holdings with the rise
in municipal yields during 1999 (following stable yields in 1998) as bonds
became priced to maturity rather than to shorter call dates.
   We continue to monitor credits closely, particularly those in the health care
sector, which is seeing some improvement from operating margin pressures last
year. We are maintaining the Fund's health care weighting since underperformance
in that sector, such as during 1999, has typically been followed by a period of
strong outperformance. Our health care focus remains on issuers that are sole
community providers, are financially flexible and have strong managements. We
believe that bonds in the 8 to 15 year maturity range continue to offer the most
attractive risk/reward profile. Municipal bonds have seen continued strength in
recent months, and we believe they are an attractive complement to other asset
classes in the "soft landing" economic environment we foresee ahead.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The objective of the Tax-Free Income Fund is to provide a high level of
current income that is exempt from federal income tax, consistent with
preservation of capital, by investing primarily in investment-grade municipal
securities.
     Such municipal securities generate interest income that is exempt from both
regular federal income tax and federal alternative minimum tax. During normal
market conditions, the Fund invests 100% of its net assets in such tax-exempt
municipal securities.

PERFORMANCE FIGURES ARE HISTORICAL AND DO NOT GUARANTEE FUTURE RESULTS.
INVESTMENT RETURNS AND PRINCIPAL VALUE WILL VARY, AND YOU MAY HAVE A GAIN OR
LOSS WHEN YOU SELL SHARES. AVERAGE ANNUAL TOTAL RETURNS INCLUDE CHANGES IN SHARE
PRICE AS WELL AS REINVESTMENT OF ALL DIVIDENDS AND CAPITAL GAINS. MANAGEMENT
FEES AND ADMINISTRATIVE EXPENSES ARE INCLUDED IN THE FUND'S PERFORMANCE;
HOWEVER, FEES AND EXPENSES ARE NOT INCORPORATED IN THE LEHMAN 5-YEAR MUNI. BOND
INDEX. THE LIPPER AVERAGES AND INDICES ARE OBTAINED FROM LIPPER ANALYTICAL
SERVICES, INC., A LARGE INDEPENDENT EVALUATOR OF MUTUAL FUNDS.

(2) Duration is a measure which reflects estimated price sensitivity to a given
change in interest rates. For example, for an interest rate change of 1%, a
portfolio with a duration of 5 years would be expected to experience a price
change of 5%. Estimated average life duration is based on current interest rates
and the Adviser's assumptions regarding the expected average life of individual
securities held in the portfolio. Implied duration is calculated based on
historical price changes of securities held by the Fund. The Adviser believes
that the portfolio's implied duration is a more accurate estimate of price
sensitivity provided interest rates remain within their historical range. If
interest rates exceed the historical range, the estimated average life duration
may be a more accurate estimate of price sensitivity.

                               [PLOT POINTS CHART]

The sum of $10,000 invested at inception (9/29/88) and held until 9/30/00 would
have grown to $21,618 in the Fund or $21,051 in the Lehman 5-Year Municipal Bond

[PHOTO]  SIT MINNESOTA TAX-FREE INCOME FUND
         SIX MONTHS ENDED SEPTEMBER 30, 2000

   Municipal bond prices rose during the six month period after bottoming in
mid-May. The Fund's price per share rose from $9.73 to $9.81 during the period
and ranged from a low of $9.55 in mid-May to a high of $9.87 in early September.
The Fund benefited from declining yields since mid-May and from stabilizing
yields in the health care sector, and provided a return of +3.56% for the six
month period ended September 29, 2000, compared to +3.58% for the Lehman 5-year
Municipal Index. The Fund's 30-day SEC yield rose from 5.42% to 5.71% during the
period and its 12-month distribution rate increased from 5.19% to 5.40%,
contrary to the general declining trend of bond yields.
   We continue to look for opportunities to increase the yield in the portfolio,
as incremental credit spreads remain wide. Purchases were made in the hospital
and other revenue sectors, which increased from 21.5% to 24.1% and from 6.0% to
7.7%, respectively. Multifamily housing bonds increased from 37.5% to 39.0%,
despite net sales. Cash decreased from 10.6% to 3.3% as assets declined from
$172.9 million to $163.4 million. Securities rated A or better decreased from
52.1% to 48.6% while non-rated holdings increased from 40.0% to 42.7%. We intend
to keep non-rated holdings around their current weighting to ensure portfolio
liquidity. The Fund's average maturity extended from 16.6 years to 17.3 years
due to the decrease in cash. Nonetheless, the Fund's implied duration, which is
based on historical price changes, increased from 7.1 years to 8.2 years,
reflecting the increased price sensitivity of the Fund's holdings with the rise
in municipal yields during 1999 (following stable yields in 1998) as bonds
became priced to maturity rather than to shorter call dates.
   We continue to monitor credits closely, particularly those in the health care
sector, which is seeing some improvement from operating margin pressures last
year. We are maintaining the Fund's health care weighting since underperformance
in that sector, such as during 1999, has typically been followed by a period of
strong outperformance. Our health care focus remains on issuers that are sole
community providers, are financially flexible and have strong managements. We
believe that bonds in the 8 to 15 year maturity range continue to offer the most
attractive risk/reward profile. Municipal bonds have seen continued strength in
recent months, and we believe they are an attractive complement to other asset
classes in the "soft landing" economic environment we foresee ahead.


                        INVESTMENT OBJECTIVE AND STRATEGY

   The investment objective of the Minnesota Tax-Free Income Fund is to provide
a high level of current income exempt from federal regular income tax and
Minnesota regular personal income tax as is consistent with the preservation of
capital.
   During normal market conditions, the Fund invests 100% of its net assets in
municipal securities that generate interest income that is exempt from regular
federal income tax and Minnesota regular personal income tax. The Fund
anticipates that substantially all of its distributions to its shareholders will
be exempt as such. For investors subject to the alternative minimum tax ("AMT"),
up to 20% of the Fund's income may be alternative minimum taxable income.

PERFORMANCE FIGURES ARE HISTORICAL AND DO NOT GUARANTEE FUTURE RESULTS.
INVESTMENT RETURNS AND PRINCIPAL VALUE WILL VARY, AND YOU MAY HAVE A GAIN OR
LOSS WHEN YOU SELL SHARES. AVERAGE ANNUAL TOTAL RETURNS INCLUDE CHANGES IN SHARE
PRICE AS WELL AS REINVESTMENT OF ALL DIVIDENDS AND CAPITAL GAINS. MANAGEMENT
FEES AND ADMINISTRATIVE EXPENSES ARE INCLUDED IN THE FUND'S PERFORMANCE;
HOWEVER, FEES AND EXPENSES ARE NOT INCORPORATED IN THE LEHMAN 5-YEAR MUNICIPAL
BOND INDEX. THE LIPPER AVERAGES AND INDICES ARE OBTAINED FROM LIPPER ANALYTICAL
SERVICES, INC., A LARGE INDEPENDENT EVALUATOR OF MUTUAL FUNDS.

(2) Duration is a measure which reflects estimated price sensitivity to a given
change in interest rates. For example, for an interest rate change of 1%, a
portfolio with a duration of 5 years would be expected to experience a price
change of 5%. Estimated average life duration is based on current interest rates
and the Adviser's assumptions regarding the expected average life of individual
securities held in the portfolio. Implied duration is calculated based on
historical price changes of securities held by the Fund. The Adviser believes
that the portfolio's implied duration is a more accurate estimate of price
sensitivity provided interest rates remain within their historical range. If
interest rates exceed the historical range, the estimated average life duration
may be a more accurate estimate of price sensitivity.

[PHOTO]  SIT BOND FUND
         SIX MONTHS ENDED SEPTEMBER 30, 2000
         -----------------------------------------------------------------------
         MICHAEL C. BRILLEY, SENIOR PORTFOLIO MANAGER
         BRYCE A. DOTY, CFA, SENIOR PORTFOLIO MANAGER

   The Sit Bond Fund provided investors with a +3.9% return for the six months
ended September 2000, compared to a +4.8% return for the Lehman Aggregate Bond
Index. The Fund's average annual total return since inception of +5.8% exceeds
the +5.4% return of the Lipper Intermediate Investment Grade Bond Fund Average.
This ranks the Fund 24th of the 99 funds comprising the Lipper Average.
   The U.S. Treasury yield curve steepened significantly during the third
quarter after changing very little during the second quarter. Shorter maturity
Treasuries declined 20-40 basis points in yield, while the 30-year Treasury
yield ended the quarter essentially unchanged. This yield curve shift was the
result of the market's perception of a slowing economy and an approaching end to
the Federal Reserve's recent series of interest rate hikes. The Fund's
government bond holdings and collateralized mortgage obligations provided the
highest returns over the last six months as Treasury buybacks by the government
and investor demand for high quality securities drove up prices. However,
corporate and asset-backed securities outperformed Treasuries and
mortgage-backed securities during the third quarter.
   Activity in the Fund reflects our expectation of continued outperformance in
the corporate, asset-backed, and collateralized mortgage obligation sectors over
the next several months. We increased the Fund's exposure to those sectors as
these sectors have a historically wide yield advantage over Treasuries. We
believe a soft landing for the U.S. economy will provide the setting for
continued outperformance.
   Looking ahead, we expect the Treasury yield curve to continue to steepen as
short rates decline with longer term rates changing little. We are assuming that
the economy will slow and inflation has likely peaked. We intend to keep the
Fund's duration at or slightly above its benchmark and expect highly rated
securities in the corporate bond and asset-backed sectors to provide the most
attractive total return opportunities.


                        INVESTMENT OBJECTIVE AND STRATEGY

     The investment objective of the Fund is to maximize total return,
consistent with preservation of capital. The Fund pursues this objective by
investing in a diversified portfolio of fixed-income securities.
     The fund will pursue its objective by investing in a diversified portfolio
or fixed-income securities which include, but are not limited to, the following:
U.S. government securities; corporate debt securities; corporate commercial
paper; mortgage and other asset-backed securities.


                                PORTFOLIO SUMMARY

                Net Asset Value   9/30/00:    $9.47 Per Share
                                  3/31/00:    $9.43 Per Share
                         Total Net Assets:   $13.5 Million
                         30-day SEC Yield:     6.63%
               12-Month Distribution Rate:     6.53%
                         Average Maturity:    17.4 Years
                       Effective Duration:     5.0 Years(1)

(1) Effective duration is a measure which reflects estimated price sensitivity
to a given change in interest rates. For example, for an interest rate change of
1.0%, a portfolio with a duration of 5 years would be expected to experience a
price change of 5%. Effective duration is based on current interest rates and
the Adviser's assumptions regarding the expected average life of individual
securities held in the portfolio.

SIT MUTUAL FUNDS
SIX MONTHS ENDED SEPTEMBER 30, 2000
--------------------------------------------------------------------------------
NOTES TO FINANCIAL STATEMENTS


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         The Sit Mutual Funds (the Funds) are 100% no-load funds, and are
         registered under the Investment Company Act of 1940 (as amended) as
         diversified (except Minnesota Tax-Free Income Fund which is
         non-diversified), open-end management investment companies, or series
         thereof. The Sit Bond Fund, Sit Minnesota Tax-Free Income Fund, and the
         Sit Tax-Free Income Fund are series funds of Sit Mutual Funds II, Inc.
         This report covers the bond funds of the Sit Mutual Funds. The
         investment objective for each Fund is as follows:

         -----------------------------------------------------------------------
                     FUND                         INVESTMENT OBJECTIVE
         -----------------------------------------------------------------------
                Money Market            Maximum current income to the
                                        extent consistent with preserving
                                        capital and maintaining liquidity.
         -----------------------------------------------------------------------
         U.S. Government Securities     High current income and safety of
                                        principal.
         -----------------------------------------------------------------------
                     Bond               Maximize total return, consistent with
                                        the preservation of capital.
         -----------------------------------------------------------------------
               Tax-Free Income          High level of current income that is
                                        exempt from federal income tax
                                        consistent with the preservation of
                                        capital.
         -----------------------------------------------------------------------
             Minnesota Tax-Free         High current income that is exempt from
                   Income               federal regular income tax and Minnesota
                                        regular personal income tax consistent
                                        with preservation of capital.

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

         Significant accounting policies followed by the Funds are summarized
         below:

         INVESTMENTS IN SECURITIES

         Securities maturing more than 60 days from the valuation date, with the
         exception of those in Money Market Fund, are valued at the market price
         supplied by an independent pricing vendor based on current interest
         rates; those securities with maturities of less than 60 days when
         acquired, or which subsequently are within 60 days of maturity, are
         valued at amortized cost, which approximates market value. When market
         quotations are not readily available, securities are valued at fair
         value based on procedures determined in good faith by the Boards of
         Directors. Pursuant to Rule 2a-7 of the Investment Company Act of 1940,
         all securities in the Money Market Fund are valued at amortized cost,
         which approximates market value, in order to maintain a constant net
         asset value of $1 per share.

54
<PAGE>

----------------------------------------------------------------------- [LOGO]


         Security transactions are accounted for on the date the securities are
         purchased or sold. Gains and losses are calculated on the
         identified-cost basis. Interest, including level-yield amortization of
         long-term bond premium and discount, is recorded on the accrual basis.

         The Minnesota Tax-Free Income Fund concentrates its investments in
         Minnesota, and therefore may have more credit risk related to the
         economic conditions in the state of Minnesota than a portfolio with
         broader geographical diversification.

         FEDERAL TAXES

         The Funds' policy is to comply with the requirements of the Internal
         Revenue Code applicable to regulated investment companies and to
         distribute all of its taxable income to shareholders. Therefore, no
         income tax provision is required. Also, in order to avoid the payment
         of any federal excise taxes, the Funds will distribute substantially
         all of their net investment income and net realized gains on a calendar
         year basis.

         Net investment income and net realized gains may differ for financial
         statement and tax purposes. The character of distributions made during
         the year for net investment income or net realized gains may also
         differ from its ultimate characterization for tax purposes.

         For federal income tax purposes the Minnesota Tax-Free Income, Tax-Free
         Income, Bond , and U.S. Government Securities Income Funds have capital
         loss carryovers of $3,832,896, $10,720,633, $478,130, and $2,883,035,
         respectively at March 31, 2000, which, if not offset by subsequent
         capital gains, will begin to expire in the years 2004 - 2008. It is
         unlikely the Board of Directors will authorize a distribution of any
         net realized gains until the available capital loss carryover is offset
         or expires.

         DISTRIBUTIONS

         Distributions to shareholders are recorded as of the close of business
         on the record date. Such distributions are payable in cash or
         reinvested in additional shares of the Funds' capital stock.
         Distributions from net investment income are declared daily and paid
         monthly for the Funds. Distributions from net realized gains, if any,
         will be made annually for each of the Funds.

         USE OF ESTIMATES

         The preparation of financial statements in conformity with generally
         accepted accounting principles requires management to make certain
         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 results. Actual
         results could differ from those estimates.

                                                                              55

NOTE 3 - EXPENSES

         INVESTMENT ADVISER

         The Funds each have entered into an investment management agreement
         with Sit Investment Associates Inc. (SIA), under which SIA manages the
         Funds' assets and provides research, statistical and advisory services,
         and pays related office rental, executive expenses and executive
         salaries. SIA also is obligated to pay all of Money Market, U.S.
         Government Securities, Bond, Tax-Free Income, and Minnesota Tax Free
         Income Funds' expenses (excluding extraordinary expenses, stock
         transfer taxes, interest, brokerage commissions, and other transaction
         charges relating to investing activities). The fee for investment
         management and advisory services is based on the average daily net
         assets of the Funds at the annual rate of:

         has voluntarily agreed to limit the flat monthly fee (and, thereby, all
         Fund expenses, except extraordinary expenses, interest, brokerage
         commissions and other transaction charges not payable by the Adviser)
         paid by the Tax-Free Income Fund to an annual rate of .70% of the
         Fund's average daily net assets in excess of $250 million and .60% of
         the Fund's average daily net assets in excess of $500 million. After

         those of non-related entities except that, to avoid duplicate
         investment advisory fees, SIA remits to each Fund an amount equal to
         all fees otherwise due to them under their investment management
         agreement for the assets invested in the Sit Money Market Fund.

(1)  Total investment return is based on the change in net asset value of a
     share during the period and assumes reinvestment of distributions at net
     asset value.

(2)  Percentages for the period ended September 30, 2000 are adjusted to an
     annual rate.
     Total Fund expenses are contractually limited to .80% of average daily net
     assets for the first $50 million in Fund net assets and .60% of average
     daily net assets for Fund net assets exceeding $50 million. However, during
     the period ended September 30, 2000, and the years ended March 31, 2000,
     1999, 1998, and 1997, the investment adviser voluntarily absorbed $127,000,
     $187,726, $126,552, $98,857, and $78,042, respectively, in expenses that
     were otherwise payable by the Fund. Had the Fund incurred these expenses,
     the ratio of expenses to average daily net assets would have been .66%,
     .71%, .80%, .80%, and .80% for each of these periods and the ratio of net
     investment income to average daily net assets would have been 5.82%, 4.84%,
     4.54%, 4.82%, and 4.63%, respectively.

     assets. However, during the period ended September 30, 2000, and the years
     ended March 31, 2000, 1999, 1998, and 1997, the investment adviser
     voluntarily absorbed $176,971, $749,173, $621,348, $171,504, and $46,819,
     in expenses that were otherwise payable by the Fund. Had the Fund incurred
     these expenses, the ratio of expenses to average daily net assets would
     have been .80% for these periods, and the ratio of net investment income to
     average daily net assets would have been 5.18%, 5.05%, 4.81%, 5.25%, and
     5.62%, respectively.
