         CHAIRMAN'S LETTER

Dear fellow shareholders:

   The past year has been a difficult one for fixed income investors. With
interest rates rising and the stellar returns of equities, investors have
rapidly moved assets away from the bond market, seeking to participate in the
fabulous returns posted by growth equity stocks through March 31, 2000. Those
investors remaining in the bond market have endured the second-worst performance
(after 1994) on record. After explaining the reasons for this weak performance,
we will provide our reasons for optimism in the coming year.
   During the first half of 1999, the effects of the global liquidity crisis
experienced in the last half of 1998 abated, and global economic growth began to
accelerate, fueled by strong demand and low commodity prices. The Federal
Reserve adopted a more restrictive monetary policy during the summer of 1999,
increasing the federal funds rate three times from 4.75% in June to 5.50% by
November. These moves effectively reversed the three easings undertaken by the
Fed in the autumn of 1998 to address the global liquidity crisis. Interest rates
rose steadily throughout 1999. In the first quarter of 2000, after fears of Y2K
economic disruptions proved to be unfounded and domestic growth actually picked
up speed from already strong levels, the Fed resumed its tightening moves,
increasing the federal funds rate to 6.00% by the end of March. Also during the
first quarter, the U.S. Treasury Department announced that it would reduce debt
by buying back longer maturity Treasury securities. Speculation as to the size
and future trend of government purchases of Treasury securities caused yields to
fall and prices to rise for long maturity Treasuries. Concerns about additional
Fed tightening, however, caused shorter duration Treasury securities to continue
to move higher in yield. As a result, the U.S. Treasury yield curve is now
inverted, with the 2-year Treasury yielding 6.48% and the 30-year Treasury
yielding 5.84%, on March 31, 2000. While an inverted yield curve is often a
precursor to a recession, we believe this inversion is the result of the Federal
Reserve's tightening posture, reduced supply from the Treasury Department's
buybacks, and expectations of relatively low long-term rates of inflation,
rather than a sign of near-term recession.

ECONOMIC OVERVIEW
   Fourth quarter 1999 real GDP growth was a whopping +7.3% annualized rate, the
sharpest gain since the first quarter of 1984. As a result, full year 1999 GDP
growth was 4.2%. This economic growth reflects the strength of consumer
spending. What is even more remarkable is that the GDP deflator, a measure of
inflation, averaged only +1.4 % for 1999.
   Looking forward, we believe personal consumption could grow at a +6.5% rate
in the first quarter, which is even faster than last year. One reason for the
accelerating rate of personal consumption is the so-called "wealth effect,"
which attempts to link increases in net worth (principally influenced by home
and financial asset values) to personal consumption. Over the past three years,
household net worth has accelerated sharply to nearly six times annual personal
income and the personal consumption rate has gone up in concert. Even though we
expect the dominant consumer sector to decelerate somewhat during 2000, only a
very severe and sustained stock market correction would materially impact
spending. Our view is supported by a study that found that it would take up to
five quarters of a sustained 15 to 20 percent decline in stock prices to impact
consumer spending materially. Economic growth will also be fueled by
accelerating government spending as Congress rushes to spend burgeoning budget
surpluses during a critical election year. Altogether, we believe the full year
2000 real GDP growth will exceed +5.0%.
   The impressive strength of the economy has raised natural concerns over
inflationary pressures, and the large March Consumer Price Index increase of
0.7% did nothing to diminish those fears. Soaring energy prices were a major
element in the March "headline" CPI of +3.7%, however, the core rate, which
excludes both food and energy, expanded at a tamer +2.4% year-over-year. Also,
OPEC has set a target of $22 - $28 per barrel price range for crude prices by
adjusting supply, which has already lowered energy prices.
   Employee compensation continues as another potential inflationary concern in
a fully-employed economy. The latest data for March, however, showing average
hourly earnings increasing at a relatively stable +3.7% rate and the
unemployment rate remaining steady at 4.1% did not flash strong

warning signals. As a result, consumer price inflation is likely to average 3.0%
in 2000, up from 2.2% in 1999. The combination of continued economic strength
and a modest rise in inflation is expected to force the Federal Reserve to
continue raising short term rates until we see a significant slowing in economic
growth. The U.S. dollar exchange rate versus major countries has been relatively
stable, and should remain so.
   Forecasts for the size of the federal budget surplus continue to rise.
Estimates project a potential surplus of $201 billion for fiscal year 2000,
which is 63% higher than last year's overage. As a result, the solvency period
extended for both the Social Security trust fund (by 3 years to 2037) and the
Medicare hospital trust fund (by 8 years to 2023). The change in fiscal fortune
has been dramatic in the sense that as recently as 1996, the Administration
predicted that the Medicare fund would run out of money in 2001.
   At the current rate of budget surplus growth, the cumulative surplus
estimates become staggering, growing as large as $8 trillion over ten years as
opposed to the Congressional Budget Office's estimate of $1.9 trillion, using
"conservative assumptions." One of the major implications of these very large
numbers is the probability of continued Treasury debt reduction. Politicians
have firmly committed to using the Social Security portion of the surplus, which
could be as high as $2 trillion over ten years, for debt reduction and the size
of the non-Social Security surplus will be so large (assuming continuation of a
favorable economy) that some of those funds may be allocated to debt reduction
as well. One forecast has Treasury debt outstanding by the end of next year
(excluding Fed holdings) at 22% of GDP, down from the peak of 40% seen in 1993
and the lowest since 1981.

STRATEGY SUMMARY
   With the inversion of the Treasury yield curve, that market has decoupled
from other fixed income sectors. In fact, even government agency bond yields are
less closely tied to Treasury yields due to a Treasury Department official's
suggestion that governmental support for debt issued by government-sponsored
enterprises (GSEs) might be eliminated. Looking forward, we expect agency debt
securities to remain vulnerable to ongoing discussions regarding their implicit
government guarantees. We expect government support, which is largely symbolic,
to be withdrawn in the next 18 to 24 months and we are currently underweighted
in this sector.
   We are much more optimistic on the corporate and asset-backed sectors. The
recent weakness in these sectors is reminiscent of last year's flight to quality
due to Y2K, which provided an opportunity to purchase corporate securities at
relatively high yields. Long-term Treasury yields look particularly unattractive
relative to the year-over-year inflation rate of +3.7%, resulting in real yields
approximating only 2.3%. In fact, we have purchased Treasury Inflation Protected
Securities (TIPS) in our bond portfolios. TIPS earn a small coupon yield (about
4%) and their principal grows at the monthly inflation rate (non-seasonally
adjusted CPI). We have positioned taxable bond portfolios with durations
slightly shorter than their benchmarks, reflecting our expectations for
inflation to approach its peak and for the Fed to continue raising short-term
rates until economic growth slows to a sustainable rate.
   In contrast to the Treasury yield curve, the municipal yield curve remains
positively sloped. Municipal bonds continue to appear attractively valued when
compared with other fixed income sectors, particularly on an after-tax basis. We
continue to monitor credits closely, particularly in the health care sector, and
remain focused on municipals in the 8- to 15-year maturity range, which we
believe continue to offer the most attractive risk/reward opportunities.
   We appreciate your interest and investment in Sit Mutual Funds, and we look
forward to assisting you in achieving your long-term investment goals.

With best wishes,

/s/ Eugene C. Sit

SIT MUTUAL FUNDS
YEAR ENDED MARCH 31, 2000

PERFORMANCE SUMMARY - BOND FUNDS

   Bond yields continued their steadily rising trend that began in the fall of
1998 with the global liquidity crisis caused by the Russian default, a Far
Eastern economic panic, and the near-collapse of the Long Term Capital hedge
fund. These factors caused the yields of 3-month Treasury bills and 30-year
Treasury bonds to reach respective lows of 3.62% and 4.71% in October 1998. The
3-Month Treasury bill yield reached a high of 5.92% in late March 2000, as the
Federal Reserve increased the federal funds rate five times to 6.00% and the
discount rate four times to 5.50% during the past 12 months in an effort to slow
economic growth. Long-term Treasury bond yields also moved higher, but then
peaked in January 2000, with the 30-year Treasury bond yield reaching 6.75%,
following the announcement of the U.S. Treasury Department's intention to buy
back longer-term Treasury debt with funds available from the budget surplus. As
a result, the Treasury yield curve is now inverted, with the 2-year Treasury
note yielding 6.48% and the 30-year Treasury bond yielding 5.84% on March 31,
2000.
   With the inversion of the Treasury yield curve, that market has decoupled
from other fixed income sectors. The 91 basis point (0.91%) decline in the
30-year Treasury bond yield since January was much more substantial than the 40
basis point decline in long-term, high (investment) grade corporate bond yields,
contributing to the underperformance of corporates for the year. All other
sector yield curves remain positively sloped, with longer maturity yields
remaining higher than shorter maturity yields. As a result, we believe Treasury
securities are unattractive relative to all other sectors.
   Municipal bond yields also moved to higher levels during the year. The Bond
Buyer 40-Bond Index rose from 5.23% on March 31, 1999 to a high of 6.32% in
January, before declining 35 basis points to 5.97% on March 31, 2000. The
relative yield of municipals, when compared to both Treasury securities and
corporate bonds on an historical basis, has remained cheaply valued for much of
the year, particularly on an after-tax basis. With the rise in yields, the
housing sector outperformed, given its stable price characteristics, while
hospital bonds lagged due to increased credit concerns and discount coupon bonds
underperformed as their prices were marked down even more to reflect potential
capital gains taxes. The municipal yield curve remains positively sloped, and we
believe that bonds in the 8- to 15-year maturity range offer the most attractive
risk/reward profile.

[PHOTO]   SIT MONEY MARKET FUND
          YEAR ENDED MARCH 31, 2000
          ----------------------------------------------------------------------
          MICHAEL C. BRILLEY, SENIOR PORTFOLIO MANAGER
          PAUL J. JUNGQUIST, CFA, SENIOR PORTFOLIO MANAGER

   The Sit Money Market Fund provided investors with a +1.36% return for the
three months ended March 31, 2000, compared to a +1.27% average return for the
Lipper Analytical Services, Money Market Fund universe. The Fund's performance
ranked 71st of 368 funds in its Lipper peer group category for the first quarter
of 2000. For the 1-year, 3-year, 5-year and since inception periods ended March
31st, the Fund's performance ranked 65th of 351, 52nd of 279, 61st of 233 and
41st of 188 funds, respectively, in its Lipper peer group. As of March 31st, the
Fund's 7-day compound yield was 5.64% and its average maturity was 30 days,
compared to 4.54% and 34 days, respectively, at March 31, 1999.
   The Federal Reserve Board increased the federal funds rate by 1.25% in five
separate 25 basis point tightenings during the past year to 6.00%, in response
to continued strong growth in the economy, commodity price inflation and
tightness in labor markets. Three-month Treasury Bill yields rose steadily over
the past year, ranging from 4.3% in April to 5.9% in March, finishing at 5.87%
on March 31st. Current yield levels imply that the market is expecting
additional tightening by the Fed in the second quarter of 2000, probably at the
May 16 FOMC meeting and perhaps at a subsequent meeting as well. The Fund has
grown substantially over the past year as Sit equity funds have been investing
short-term cash flows in the Fund. 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 continues to be strong, and global economic activity appears to be
strengthening, we do not foresee a significant impact on the short-term
creditworthiness of top tier commercial paper issuers in general. 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
          YEAR ENDED MARCH 31, 2000
          ----------------------------------------------------------------------
          MICHAEL C. BRILLEY, SENIOR PORTFOLIO MANAGER
          BRYCE A. DOTY, CFA, SENIOR PORTFOLIO MANAGER

   The U.S. Government Securities Fund provided investors a +2.92% return for
the past 12 months. The 12-month return for the Lipper U.S. Government Fund
universe average and the Lehman Intermediate Bond Index was +0.8% and +2.4%,
respectively. The Fund holds a 4-Star Overall rating by Morningstar out of 1,680
funds in the taxable bond category. Morningstar also rated the Fund #3 in the
Best 5-Year Return category and #4 in the Highest 5-Year Rating category for its
combined low risk and high return characteristics. Both Morningstar categories,
as of 3/7/00, contained 92 funds.
   The U.S. Treasury yield curve inverted over the past 12 months. Specifically,
the yield of 2-year maturity U.S. Treasuries rose 1.51% to 6.48%, while 30-year
maturity U.S. Treasury yields rose only 0.22% to 5.84% on March 31st.
   The rise in interest rates slowed the rate of prepayments in the mortgage
pass-through sector, which raised the yield that the Fund earned on its mortgage
holdings. As a result, mortgage pass-through holdings provided the highest
source of return in the Fund over the past 12 months. Conversely, the rise in
bond yields caused prices to decline in the Fund's longer duration
collateralized mortgage obligation holdings.
   Investment activity for the period involved reducing the Fund's weighting in
U.S. Treasury securities and purchasing mortgage pass-through securities with
higher yields. As a result of this sector shift, combined with lower mortgage
refinancing activity, the Fund's 30-day SEC yield rose from 5.25% on March 31,
1999 to 6.76% on March 31, 2000.
   The inversion of the Treasury yield curve was accelerated by the U.S.
Treasury Department's decision to purchase long term Treasuries to reduce debt.
As a result, the shift in U.S. Treasury yields has decoupled from yield shifts
in other sectors. As a result, the Fund will continue to underweight U.S.
Treasuries and focus on mortgage pass-through securities and collateralized
mortgage obligations that provide significantly higher yields and relative price
stability. The Fund's duration is slightly shorter than its benchmark,
reflecting our expectations for slightly rising inflation and for the Federal
Reserve to continue raising short-term rates until economic growth slows to a
sustainable rate.


                        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  3/31/00:   $ 10.22 Per Share
                                  3/31/99:   $ 10.51 Per Share
                         Total Net Assets:   $135.8 Million
                         30-day SEC Yield:      6.76%
               12-Month Distribution Rate:      5.68%
                         Average Maturity:     15.7 Years
                       Effective Duration:      3.0 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
          YEAR ENDED MARCH 31, 2000
          ----------------------------------------------------------------------
          MICHAEL C. BRILLEY, SENIOR PORTFOLIO MANAGER
          DEBRA A. SIT, CFA, SENIOR PORTFOLIO MANAGER

   Municipal yields rose during the past 12 months. The Fund provided a return
of +1.58% for the quarter and -2.98% for the fiscal year ended March 31, 2000,
compared to +1.20% and +0.89%, respectively, for the Lehman 5-year Municipal
Index. The Fund's return, which was hurt by greater price declines in longer
duration securities and widening yield spreads in health care bonds, improved
during the most recent quarter as longer-term bond yields reversed their rising
trend. The Fund's 30-day SEC yield increased from 4.54% to 5.52% during the
year.
   The rise in yields also caused the Fund's implied duration to extend from 6.9
years to 7.7 years as some of the bonds in the portfolio became priced to
maturity rather than to shorter call dates. Longer maturity holdings were sold
to contain the Fund's duration extension and the Fund's average maturity was
unchanged at 17.2 years. Although we expect the Federal Reserve to continue to
raise rates, we intend to maintain the Fund's current duration positioning in
anticipation of lower rates later this year.
   Fund assets declined from $895.4 million to $582.5 million during the past 12
months due to anticipated shareholder withdrawals for tax payments, tax loss
selling in December and a significant distribution in-kind to a major group of
shareholders into a separately managed fund. Nonetheless, most sector weightings
ended the year little changed. Multifamily housing bonds increased from 25.9% to
30.5% and other revenue bonds increased from 7.8% to 11.1%. Single family
housing bonds decreased from 13.8% to 12.1% and continue to gradually be reduced
as the Fund avoids securities subject to the alternative minimum tax (AMT).
Holdings in transportation bonds were advance refunded earlier in the year and
sold at relatively low yields. Securities rated A or better decreased from 71.0%
to 60.6%, in part, as the Fund has sought to retain its positions in higher
(i.e., 6.25% to 7.25%) yielding securities and, in part, as cash (held primarily
for anticipated shareholder tax payments) decreased from 11.0% to 4.3%. Due to
recent ratings actions in the multifamily sector, the Fund held 1.1% in
securities rated less than BBB. We are monitoring these credits closely, as well
as those in the health care sector, which was subject to operating margin
pressure last year. We intend to maintain the Fund's weighting in health care
bonds as underperformance in that sector has historically been followed by a
period of strong outperformance. Our focus remains on issuers that are sole
community providers, are financially flexible and have strong managements.
   Municipal bonds remain very attractively valued, particularly on an after-tax
basis. Intermediate maturity bonds are currently yielding only slightly less
than longer bonds, and we believe that bonds in the 8 to 15 year maturity range
offer the most attractive risk/reward profile.

                        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 in investment-grade municipal securities.

     Such municipal securities generate interest that is exempt from regular
federal income taxes. Of the municipal securities in which the Fund invests,
100% will be rated investment grade at time of purchase. The Adviser does not
intend to invest in securities that generate interest income treated as a tax
preference for alternative minimum taxable income purposes.

(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.

          YEAR ENDED MARCH 31, 2000

   Municipal yields rose during the past 12 months. The Fund provided a return
of +1.68% for the quarter and -2.84% for the fiscal year ended March 31, 2000,
compared to +1.20% and +0.89%, respectively, for the Lehman 5-year Municipal
Index. The Fund's return, which was hurt by greater price declines in longer
duration securities and widening yield spreads in health care bonds, improved
during the most recent quarter as longer-term bond yields reversed their rising
trend. The Fund's 30-day SEC yield rose from 4.52% to 5.42% during the year.
   The rise in yields also caused the Fund's implied duration to extend from 6.8
years to 7.1 years as some of the bonds in the portfolio became priced to
maturity rather than to shorter call dates. Longer maturity holdings were sold
to keep the Fund's duration from extending further, causing the Fund's average
maturity to decrease from 17.7 years to 16.6 years. Although we expect the
Federal Reserve to continue to raise rates, we intend to maintain the Fund's
current duration positioning in anticipation of lower rates later this year.
   Fund assets declined from $271.3 million to $172.9 million during the past 12
months due to anticipated withdrawals for tax payments, tax loss selling in
December and a significant exchange by a major group of shareholders into a
separately managed fund. Nonetheless, most sector weightings ended the year
little changed. Cash was 10.6% on March 31, 2000 as a result of recent inflows,
compared with 11.9% held one year ago, in part, for anticipated shareholder tax
payments. Multifamily housing bonds increased from 34.0% to 37.5%, while single
family housing bonds decreased from 11.0% to 9.5%. Securities rated A or better
decreased from 54.5% to 52.1% as non-rated holdings increased from 37.0% to
40.0%. The Fund has sought to retain its positions in higher (i.e., 6.50% to
7.50%) yielding securities while preserving liquidity as well. Thus, non-rated
holdings will likely remain around their current weighting. We continue to
monitor credits closely, particularly those in the health care sector, which was
subject to operating margin pressure last year. We intend to maintain the Fund's
weighting in health care bonds as underperformance in that sector has
historically been followed by a period of strong outperformance. Our focus
remains on issuers that are sole-community providers, are financially flexible
and have strong managements.
   Municipal bonds remain very attractively valued, particularly on an after-tax
basis. Intermediate maturity bonds are currently yielding only slightly less
than longer bonds, and we believe that bonds in the 8 to 15 year maturity range
offer the most attractive risk/reward profile.


                        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.

     The Fund will endeavor to invest 100% of its assets in municipal
securities, the income from which is exempt from federal regular 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.

                               [PLOT POINTS CHART]

The sum of $10,000 invested at inception (12/1/93) and held until 3/31/00 would
have grown to $13,604 in the Fund or $13,376 in the Lehman 5-Year Municipal Bond
Index assuming reinvestment of all dividends and capital gains.

[PHOTO]   SIT BOND FUND
          YEAR ENDED MARCH 31, 2000
          ----------------------------------------------------------------------
          MICHAEL C. BRILLEY, SENIOR PORTFOLIO MANAGER
          BRYCE A. DOTY, CFA, SENIOR PORTFOLIO MANAGER

   The Sit Bond Fund provided investors a +0.9% return for the past 12 months.
The 12-month return for the Lipper Intermediate Investment Grade Bond Fund
universe average and the Lehman Aggregate Bond Index was +1.0% and 1.9%,
respectively. For the period since its inception, the Fund's return ranked in
the top 25% of its Lipper universe (out of 102 funds).
   The U.S. Treasury yield curve inverted over the past 12 months. Specifically,
the yield of 2-year maturity U.S. Treasuries rose 1.51% to 6.48%, while 30-year
maturity U.S. Treasury yields rose only 0.22% to 5.84% on March 31st.
   The rise in interest rates slowed the rate of prepayments in the mortgage
pass-through sector, which raised the yield that the Fund earned on its mortgage
holdings. As a result, mortgage pass-through holdings provided the highest
source of return in the Fund over the past 12 months. Conversely, the rise in
bond yields caused prices to decline in the Fund's longer duration
collateralized mortgage obligation, corporate, and asset-backed holdings.
   Activity in the Fund involved two significant sector shifts over the past 12
months. Early in the period, the Fund reduced corporates along with a smaller
reduction in asset- and mortgage-backed securities. This more conservative
positioning was due to expected weakness in most sectors because of Y2K concerns
and expectations of a flight-to-quality similar to last year. September marked
the end of five months of weakness for most sectors. We believe that investor
anticipation of illiquidity at year-end caused many sectors to underperform
prematurely. The Fund, then, reversed its sector shift by selectively purchasing
corporate and asset-backed securities in order to beat the anticipated rush of
pent-up demand in these sectors.
   The inversion of the Treasury yield curve was accelerated by the U.S.
Department's decision to purchase long-term Treasuries to reduce debt. As a
result, the shift in U.S. Treasury yields has decoupled from yield shifts in
other sectors, which we think provides an opportunity for the Fund. More simply
put, investment-grade corporate and asset-backed securities, which are currently
yielding 7.50% to 8.25%, respectively, look attractively valued relative to
long-term Treasury securities yielding less than 6.00%. The Fund's duration is
slightly shorter than its benchmark, reflecting our expectations for slightly
rising inflation and for the Federal Reserve to continue raising short-term
rates until economic growth slows to a sustainable rate.


                        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  3/31/00:   $ 9.43 Per Share
                                  3/31/99:   $ 9.95 Per Share
                         Total Net Assets:   $12.2 Million
                         30-day SEC Yield:     7.01%
               12-Month Distribution Rate:     6.07%
                         Average Maturity:    16.9 Years
                       Effective Duration:     4.7 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
MARCH 31, 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 with the preservation of capital
                         and maintenance of liquidity.

     U.S. Government     High current income and safety of principal.
        Securities

         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-      High level of current income that is exempt from
      Free Income        federal regular income tax and Minnesota regular
                         personal income tax, consistent with the 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.

     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.

     Undistributed net investment income and accumulated net realized gains
     (losses) from the Statement of Changes in Net Assets have been increased
     (decreased) by current permanent book-to-tax differences resulting in
     reclassification of additional paid-in capital as follows:

                                   Undistributed     Accumulated      Additional
                                  net investment    net realized        paid-in
                                      income        gains (losses)      capital
                                      ------        --------------    ---------

     Tax-Free Income                   8,043           (10,015)          1,972
     U.S. Government Securities        1,166            (1,166)             --
     Bond                             (1,172)            1,172              --

     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

     For the period April 1, 1995, through December 31, 2000, the Adviser 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 December 31, 2000, this
     voluntary fee waiver may be discontinued by the Adviser in its sole
     discretion.

     For the period April 1, 1995, through December 31, 2000, the Adviser 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 U.S.
     Government Securities Fund and Money Market Fund to an annual rate of .80%
     and .50%, respectively of the Fund's average daily net assets. After
     December 31, 2000, this voluntary fee waiver may be discontinued by the
     Adviser in its sole discretion.

     As of March 31, 2000, the Bond Fund had invested $9,000 in the Sit Money
     Market Fund. The terms of such transactions were identical to 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)  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 periods ended March 31, 2000, 1999, 1998, 1997, and 1996, the
     investment adviser voluntarily absorbed $187,726, $126,552, $98,857,
     $78,042, and $66,862, 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 .71%, .80%, .80%, .80%, and .80%
     for each of these periods and the ratio of net investment income to average
     daily net assets would have been 4.84%, 4.54%, 4.82%, 4.63%, and 5.05%,
     respectively.

INDEPENDENT AUDITORS' REPORT

The Board of Directors and Shareholders
Sit Money Market Fund, Inc.
Sit U.S. Government Securities Fund, Inc.
Sit Mutual Funds II, Inc.:

     We have audited the accompanying statements of assets and liabilities,
including the schedules of portfolios of investments, of Sit Money Market Fund,
Inc., Sit U.S. Government Securities Fund, Inc., Sit Bond Fund (a series of Sit
Mutual Funds II, Inc.), Sit Tax-Free Income Fund (a series of Sit Mutual Funds
II, Inc.), and Sit Minnesota Tax-Free Income Fund (a series of Sit Mutual Funds
II, Inc.), as of March 31, 2000; the related statements of operations for the
year then ended; the statements of changes in net assets for each of the years
in the two-year period then ended; and the financial highlights as presented in
note 4 to the financial statements. These financial statements and the financial
highlights are the responsibility of the Funds' management. Our responsibility
is to express an opinion on these financial statements and the financial
highlights based on our audits.
     We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform our 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. Our procedures included confirmation of
securities owned as of March 31, 2000, 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 Sit
Money Market Fund, Sit U.S. Government Securities Fund, Sit Bond Fund, Sit
Tax-Free Income Fund, and Sit Minnesota Tax-Free Income Fund as of March 31,
2000 and the results of their operations, the changes in their net assets, and
their financial highlights for the periods stated in the first paragraph above,
in conformity with accounting principles generally accepted in the United States
of America.
