	Sit Mutual Funds      Six Months Ended September 30, 2005      Chairman’s Letter

Dear fellow shareholders:

        Short and intermediate interest rates rose, and longer-term rates fell during the 6 months ended September 30, 2005. The Federal Reserve raised the federal funds rate by 0.25% at each of its four meetings over the period, which left the rate target at 3.75% at the end of September. Market participants thought that the Fed might refrain from raising rates at its September 20^th meeting, so it could assess the impact of the hurricanes. However, the Fed demonstrated its conviction to contain inflation by raising rates another 0.25% at that meeting. The Fed also indicated that it will continue to raise rates at a “measured pace”.

        Recent economic data have begun to show the effects of Hurricane Katrina. High energy costs are having an impact on consumer spending, particularly at lower income levels. Personal consumption expenditures dropped in the month of August, but the decline was mostly the result of a reduction in durable goods spending, which was boosted in July by vehicle sales incentives. The consumer will continue to play a large role in the economy, as two-thirds of GDP is comprised by the consumer sector. Real personal consumption for August was still up +3.5% year over year, but down from +4.5% in June.

        Employment, another determinant of future consumer spending, has remained healthy. Reported payrolls declined 8,000 in September, but would have increased around 200,000 after adjusting for hurricane-related payroll losses, in line with the prior twelve months’ average. Job creation has averaged 196,000 per month this year, on top of a strong 183,000 per month rate in 2004. In addition to strong employment, the latest measures of manufacturing activity have also been remarkably strong.

        With respect to pricing trends, as expected, higher energy prices are making their way into inflation measures. The Consumer Price Index (CPI) rose +0.5% for the second consecutive month in August as gasoline prices jumped +7.7%. Year over year the CPI is up +3.6%. There may be more to come in terms of higher energy prices, as the CPI and PPI inflation measures have not yet captured much of the effects of Hurricane Katrina. The Bureau of Labor Statistics stated that, “Over 90% of the prices for August were collected prior to August 29^th, the date when Hurricane Katrina struck the Gulf Coast.” An early warning sign may be the ISM prices paid index, which surged again in September to 78.0 from 62.5 in August and 48.5 in July, as 60 percent of supply executives reported paying higher prices.

        The Congressional Budget Office (CBO) estimates that real GDP will grow about 0.5 percentage points slower over the second half of 2005 due to the hurricanes, with most of that slowing occurring in the third quarter. The CBO also anticipates that with private and government support for recovery and rebuilding, GDP growth will not be much affected in the fourth quarter. The CBO expects GDP to return to its previous trend by early 2006 and to accelerate subsequently as rebuilding raises overall economic activity.

        The cumulative budget deficit has been $352.6 billion through eleven months of fiscal year 2005, an $84.9 billion improvement over last year. However this year’s budget deficit improvement will likely be short lived. Congress has already approved more than $60 billion in emergency spending related to Hurricane Katrina, which could ultimately increase to $150 billion to $200 billion.

        In summary, based on a slightly weaker outlook for consumer spending in the third quarter, but a more optimistic viewpoint regarding other effects of the hurricanes on second half growth, we now expect +3.5% real GDP growth in the third quarter and +3.8% growth in the fourth quarter. Depending on the speed of the

2

rebuilding process, we forecast stronger growth will emerge in 2006. Our full-year 2005 real GDP growth forecast remains approximately +3.6%, which compares with +4.2% in 2004.

Strategy Summary

        We expect the yield curve to continue to flatten, with short rates rising more than rates for longer maturities. It appears likely that the Fed will maintain its tightening stance as long as economic growth is solidly above +3.0% and signs of inflation are evident. It seems the Fed has discounted the effects of Hurricane Katrina as having a short-term impact and that it will continue its course of increasing rates at a “measured pace.” Fed policy is complicated by higher energy costs acting both as a drag on the economy, and a source of inflationary pressure. Because the CPI has edged higher to +3.6% year over year, we expect the Fed will raise its rate target a further +0.25% at two of the next three meetings (meetings in November, December and the end of January) to bring the Fed Funds target to 4.25%. By the March 28^th, 2006 meeting, there should be more clarity on the direction of the economy, inflation, and the recovery efforts following the hurricanes. Long-term rates will likely move inversely with the direction of oil prices for the near term. Another factor weighing on the market is the uncertainty surrounding the appointment of Ben Bernanke, who will replace longtime Fed Chairman Alan Greenspan in early 2006.

        We continue to monitor these issues and invest accordingly. We are focusing on securities whose structures offer higher current yields at the expense of reduced price appreciation potential. The rise in interest rates should help slow refinancing activity in the mortgage sector, and the expectation of more stable prepayment rates should result in increased investor demand.

        Municipal portfolios also remain focused on securities that provide incremental yield, and remain defensively positioned with durations shorter than their benchmarks. We believe our focus on income will contribute to attractive relative returns, and as interest rates move higher, our short durations will allow us to reinvest at higher levels.

        Fixed income investments are an important component of a well-diversified long-term portfolio. We believe that the Sit bond funds, with their dual objectives of high income and stability of principal, offer an attractive risk/reward profile to complement equity holdings. We appreciate your continued interest and investment in Sit Mutual Funds and look forward to assisting you in achieving your long-term investment goals.

With best wishes,

Eugene C. Sit, CFA
Chairman and Chief Investment Officer

     Sit Mutual Funds
      Six Months Ended September 30, 2005
      Performance Summary – Bond Funds

        The U.S. Treasury yield curve continued to flatten during the six-month period as shorter maturity yields rose and longer maturity yields declined. The Federal Reserve increased its rate target by 25 basis points at each of its four meetings during the period, bringing the federal funds rate to 3.75%. Treasury bill yields rose more than 75 basis points during the period while 2-year Treasury yields rose only 39 basis points. 10-year and 30-year yields fell 16 and 19 basis points, respectively, as investors continued to react to long-term inflation expectations. As short-term rates and oil prices have continued to rise, long-term bondholders have reduced economic growth and long-term inflation expectations, leading to the decrease in long-term yields over the period.

        The flattening yield curve caused intermediate maturity taxable bonds to perform worse than longer maturity bonds. With regard to taxable market sectors, asset backed securities provided the worst returns, reflecting concerns about how a weaker economy and high energy costs could impact consumers and lead to higher delinquencies. There was little dispersion in returns among other sectors as Treasuries and corporates posted similar returns for the six-month period.

        The municipal yield curve flattened somewhat during the period as short yields increased only slightly and intermediate term and longer term yields dropped. Despite the flattening yield curve environment over the last year, the municipal yield curve remains quite positively sloped, with approximately 125 basis points greater yield differential between 2-year and 30-year maturity AAA general obligation issues than between comparable maturity Treasuries. Investors have continued to seek out yield, which drove demand for tobacco settlement revenue bonds, and other high yield bonds, making industrial development bonds the best performing sector over the past six months. The hospital sector was the next best performing sector, and housing bonds lagged.

        Fixed income funds remain defensively positioned, with durations shorter than respective benchmarks in anticipation of more attractive, higher-yielding reinvestment opportunities as interest rates move higher. Our focus on securities that provide high levels of income and relative price stability should continue to provide attractive relative returns in the months ahead.

     Sit Mutual Funds       Average Annual Total Returns for Periods Ended December 31, 2004

The tables on the next page show the Funds’ average annual total returns (before and after taxes) and the change in value of a broad-based market index over various periods ended December 31, 2004. The index information is intended to permit you to compare each Fund’s performance to a broad measure of market performance. The after-tax returns are intended to show the impact of federal income taxes on an investment in a Fund. The highest individual federal marginal income tax rate in effect during the specified period is assumed, and the state and local tax impact is not reflected.

A Fund’s “Return After Taxes on Distributions” shows the effect of taxable distributions (dividends and capital gain distributions), but assumes that you still hold the fund shares at the end of the period and so do not have any taxable gain or loss on your investment in the Fund.

A Fund’s “Return After Taxes on Distributions and Sale of Fund Shares” shows the effect of both taxable distributions and any taxable gain or loss that would be realized if the Fund shares were purchased at the beginning and sold at the end of the specified period.

The Funds’ past performance, before and after taxes, is not an indication of how the Funds will perform in the future. Your actual after-tax returns depend on your own tax situation and may differ from those shown. After-tax returns reflect past tax effects and are not predictive of future tax effects. After-tax returns are not relevant to investors who hold their Fund shares in a tax-deferred account (including a 401(k) or IRA account).

      Six Months Ended September 30, 2005
      Michael C. Brilley, Senior Portfolio Manager
      Mark H. Book, CFA, Portfolio Manager

        The Sit Money Market Fund returned +1.37% for the six months ended September 30, 2005 compared to +1.60% for the 3-month U.S. Treasury Bill. As of September 30th, the Fund’s 7-day compound yield was 3.26% and its average maturity was 24 days.

        The Federal Reserve increased its rate target by 25 basis points at each of its four meetings during the period, bringing the federal funds rate to 3.75%. Market participants thought that the Fed might refrain from raising rates at its September 20^th meeting, so it could assess the impact of the hurricanes. However, the Fed demonstrated its conviction to contain inflation by raising rates another 0.25% at that meeting. The Fed also indicated that it will continue to raise rates at a “measured pace.” Because inflation has begun to edge higher, we expect that the Federal Reserve will continue on the path of raising interest rates. We believe the Fed will most likely increase the federal funds target by 25 basis points at two of the next three FOMC meetings (meetings in November, December, and late January) to bring the target rate to 4.25%. By the March 28^th, 2006 meeting, there should be more clarity on the direction of the economy, inflation, and the recovery efforts following the hurricanes.

        The Fund has maintained its average maturity near the short end of its customary 20-40 day range as the 3-Month Treasury Bill yield increased 77 basis points over the past six months. The Fund will maintain its rather short average maturity in anticipation of earning higher yields as the Fed continues to raise short-term rates. If the pace of tightening slows or ceases, we expect to extend the average maturity to the middle or longer end of its customary range. The Fund continues to invest in companies with top-tier credit quality.

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.

Performance is historical and assumes reinvestment of all dividends and capital gains. Money funds are neither insured nor guaranteed by the U.S. Government. There is no assurance that a fund will maintain a $1 share value. Yield fluctuates. Past performance is not a guarantee of future results. Management fees and administrative expenses are included in the Fund’s performance; however, fees and expenses are not incorporated in the 3-Month U.S. Treasury Bill. The Lipper returns are obtained from Lipper Analytical Services, Inc., a large independent evaluator of mutual funds.

GROWTH OF $10,000

The sum of $10,000 invested at inception (11/1/93) and held until 9/30/05 would have grown to $15,449 in the Fund or $15,878 in the 3-Month U.S. Treasury Bill assuming reinvestment of all dividends and capital gains.

     Sit U.S. Government Securities Fund
      Six Months Ended September 30, 2005
      Senior Portfolio Managers, Michael C. Brilley and Bryce A. Doty, CFA
      Portfolio Manager, Mark H. Book, CFA

        The Sit U.S. Government Securities Fund provided investors with a +1.80% return during the past six months while the Lehman Intermediate Government Bond Index returned +1.77%. The Fund’s 30-day SEC yield was 4.07% and its 12-month distribution rate was 3.74%.

        The yield curve flattened during the period as the Federal Reserve continued raising short-term interest rates. The Fed increased its federal funds target level 0.25% to 3.75% on September 20, 2005. This was the eleventh consecutive 0.25% increase since June of last year, when the Fed began raising its target rate. Despite the higher short-term rates, longer maturity U.S. Treasury yields declined, reflecting the market’s belief that the Fed’s actions will be successful in containing inflation. As a result, longer maturity securities performed better than shorter maturity securities. The Fund’s allocation to U.S. Treasuries was the strongest performing sector, as it had a longer average maturity than the other sectors. The Fund’s collateralized mortgage obligations (CMO’s) also outperformed the benchmark as this sector generated higher levels of income than the benchmark. Despite the high levels of income generated by the agency mortgage pass-throughs, the returns from this sector just matched that of the benchmark.

        The bond market has recently been driven by oil prices and the Fed. While higher energy costs resulting from the recent hurricanes have produced significant inflationary pressures, data suggests that the economy continues to grow at relatively strong levels. We expect that this combination of economic growth and higher inflation will result in higher interest rates overall, with shorter term rates rising faster than longer term rates. Within this interest rate environment, we continue to emphasize securities that provide both high levels of income and low levels of price sensitivity to changes in interest rates. Within the Fund, we accomplish this focus through ownership of high coupon mortgage pass-through securities, as has consistently been the case since the Fund’s inception. These securities continue to provide a strong track record of providing attractive income return regardless of changes in underlying interest rates.

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 9/30/05:	$10.61 Per Share
	3/31/05:	$10.62 Per Share
	Total Net Assets:	$262.9 Million
	30-day SEC Yield:	4.07%
	12-Month Distribution Rate:	3.74%
	Average Maturity:	20.7 Years
	Effective Duration:	2.9 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 Tax-Free Income Fund
      Six Months Ended September 30, 2005
      Senior Portfolio Managers
      Michael C. Brilley    •   Debra A. Sit, CFA   •   Paul J. Jungquist, CFA

        The Sit Tax-Free Income Fund provided a +2.12% return for the six months ended September 30, 2005, compared with a return of +1.81% for the Lehman 5-Year Municipal Bond Index. The Fund’s 30-day SEC yield was 4.36% and its 12-month distribution rate was 3.75%, compared with 4.43% and 3.83%, respectively, six months ago.

        Despite four Federal funds rate increases totaling 100 basis points, municipal yields were fairly stable during the period. Short term tax-exempt yields rose approximately 0.30%, longer term yields fell approximately 0.20% and intermediate yields were little changed. The Fund benefited from its investments in callable, high coupon securities that provided above average income. The Fund also benefited from its holdings in several distinct sectors, including the hospital, industrial revenue, multifamily housing, and other revenue sectors, which includes tax increment bonds. These sectors saw price stability or gains as investors continued to seek yield. Sectors which underperformed totaled less than 5.0% of portfolio holdings.

        The Fund’s structure was little changed during the period with the greatest sector shifts being a 1.1% decrease in multifamily housing to 16.2% and a 1.1% increase in utilities to 3.7%. In addition, escrowed to maturity and prerefunded bonds increased from 1.1% to 2.9% as several issues were advance refunded during the period. Securities rated less than A increased slightly from 34.8% to 37.0%, reflecting the addition of shorter duration BBB rated securities at attractive yields. A significant portion of the Fund’s investments is invested in AAA rated insured bonds, and the average credit quality of the Fund remains A.

        We expect interest rates to move higher in 2006 as economic growth remains solid with rebuilding from Hurricane Katrina and inflation concerns increase as higher energy prices work their way into the system. The Fund’s implied duration of 3.6 years, which was little changed from six months ago, is relatively short to reduce the risk of price depreciation as interest rates rise. In addition, this short duration will allow the Fund to take advantage of attractive reinvestment opportunities at higher yield levels in the coming year.

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.

*As of 9/30/05.	**Not annualized.

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 returns 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.

GROWTH OF $10,000

The sum of $10,000 invested at inception (9/29/88) and held until 9/30/05 would have grown to $27,232 in the Fund or $27,029 in the Lehman 5-Year Municipal Bond Index assuming reinvestment of all dividends and capital gains.

     Sit Minnesota Tax-Free Income Fund
      Six Months Ended September 30, 2005
      Senior Portfolio Managers
      Michael C. Brilley    •   Debra A. Sit, CFA   •   Paul J. Jungquist, CFA

        The Sit Minnesota Tax-Free Income Fund provided a +2.78% return for the six months ended September 30, 2005, compared with a return of +1.81% for the Lehman 5-Year Municipal Bond Index. The Fund’s 30-day SEC yield was 4.31% and its 12-month distribution rate was 4.21%, compared with 4.49% and 4.33%, respectively, six months ago.

        Despite four federal funds rate increases totaling 100 basis points, municipal yields were fairly stable during the period. Short term tax-exempt yields rose approximately 0.30%, longer term yields fell approximately 0.20% and intermediate yields were little changed. The Fund benefited from its holdings in several distinct sectors, including the multifamily housing, hospital, industrial revenue, lease, and other revenue sectors, the latter which includes tax increment bonds. These sectors saw price stability or gains as investors continued to seek yield. Sectors which underperformed included the single family housing sector, as prepayment fears offset the potential for price gains, and the Fund’s lower yielding general obligation bond holdings.

        During the period, several issues held by the Fund were refunded or advance refunded. Multifamily sector holdings decreased by 8.7% to 23.2%, industrial revenue bonds decreased by 1.5% to 6.2%, and general obligation and education issues both decreased by about 1.0%. A number of prerefunded holdings were sold, taking advantage of price gains. Nonetheless, the Fund held a 5.7% weighting in that sector at the end of September, compared to 0.6% six months ago. Purchases focused on securities that provided attractive risk-adjusted yields. Hospital and lease holdings both increased by just over 2.0% to 21.6% and 4.1%, respectively, while single family bonds increased by 3.0% to 5.8%. Along with the refunding activity and sales, nonrated holdings decreased by 5.9% to 31.4%. The Fund’s average credit quality remains A.

        We expect interest rates to move higher in 2006 as economic growth remains solid with rebuilding from Hurricane Katrina and inflation concerns increase as higher energy prices work their way into the system. The Fund’s implied duration was 4.1 years, which was little changed from six months ago, and is relatively short to reduce the risk of price depreciation as interest rates rise. In addition, this short duration will allow the Fund to take advantage of attractive reinvestment opportunities at higher yield levels in the coming year.

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.

*As of 9/30/05.	**Not annualized.

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 returns 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.

GROWTH OF $10,000

The sum of $10,000 invested at inception (12/1/93) and held until 9/30/05 would have grown to $18,344 in the Fund or $17,789 in the Lehman 5-Year Municipal Bond Index assuming reinvestment of all dividends and capital gains.

     Sit Florida Tax-Free Income Fund
      Six Months Ended September 30, 2005
      Senior Portfolio Managers
      Michael C. Brilley   w Debra A. Sit, CFA   w Paul J. Jungquist, CFA

        The Sit Florida Tax-Free Income Fund provided a +2.00% return for the six months ended September 30, 2005, compared with a return of +1.81% for the Lehman 5-Year Municipal Bond Index. The Fund’s 30-day SEC yield was 4.18% and its 12-month distribution rate was 3.06%, compared with 4.23% and 2.93%, respectively, six months ago.

        Despite four federal funds rate increases totaling 100 basis points, municipal yields were fairly stable during the period. Short term tax-exempt yields rose approximately 0.30%, longer term yields fell approximately 0.20% and intermediate yields were little changed. The Fund benefited from its investments in callable, high coupon securities that provided above average income. The Fund also benefited from its holdings in several distinct sectors, including the hospital, multifamily, and other revenue sectors, which includes tax increment bonds. These sectors saw price stability or gains as investors continued to seek yield. Sectors which underperformed included prerefunded bonds and utility bonds, as shorter duration holdings were negatively impacted by the rise in yields.

        The Fund’s structure shifted as assets grew by 30% over the period. Purchases were made primarily in multifamily bonds which increased 5.2% to 18.0%, and in other revenue bonds which increased 4.1% to 13.1%. Utility holdings also increased from 2.6% to 4.3%. The Fund’s hospital sector weighting was unchanged while insured bonds were decreased from 56.7% to 48.4%. Finally, escrowed to maturity and prerefunded bonds increased from 2.4% to 7.1% as several issues were advance refunded during the period. Securities rated less than A increased from 19.2% to 28.8%, reflecting the purchase of shorter duration BBB rated securities at attractive yields. The average credit quality of the Fund, however, remains AA-.

        We expect interest rates to move higher in 2006 as economic growth remains solid with rebuilding from Hurricane Katrina and inflation concerns increase as higher energy prices work their way into the system. The Fund’s implied duration increased to 3.2 years, compared to 2.6 years six months ago, as the rise in shorter term yields made it more attractive to lengthen slightly. The Fund remains defensively positioned relative to its benchmark to reduce the risk of price depreciation as interest rates rise. In addition, this short duration will allow the Fund to take advantage of attractive reinvestment opportunities at higher yield levels in the coming year.

INVESTMENT OBJECTIVE AND STRATEGY

        The objective of the Florida Tax-Free Income Fund is to provide a high level of current income that is exempt from federal regular income tax by investing in securities that are exempt from the Florida intangibles tax.

        The Fund seeks to achieve its objective by investing primarily in municipal securities that generate interest income that is exempt from regular federal income tax and that are exempt from the Florida intangible personal property tax. During normal market conditions, the Fund invests 100% (and, as a fundamental policy, no less than 80%) of its net assets in such tax-exempt municipal securities. The Fund may invest up to 10% of its assets in securities that generate interest income subject to federal alternative minimum tax.

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 returns 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.

GROWTH OF $10,000

The sum of $10,000 invested at inception (12/31/03) and held until 9/30/05 would have grown to $10,500 in the Fund or $10,338 in the Lehman 5-Year Municipal Bond Index assuming reinvestment of all dividends and capital gains.

     Sit Mutual Funds
      Notes to Financial Statements

(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 and Florida Tax-Free Income Funds which are non-diversified), open-end management investment companies, or series thereof. The Sit Minnesota Tax-Free Income Fund, and the Sit Tax-Free Income Fund are series funds of Sit Mutual Funds II, Inc. The Sit Florida Tax-Free Income Fund is a series fund of Sit Mutual Funds Trust. Each fund has 10 billion authorized shares of capital stock. Shares in the U.S. Government Securities Fund have a par value of $0.01, and shares in other funds have a par value of $0.001. This report covers the bond funds of the Sit Mutual Funds. The investment objective for each Fund is as follows:

Fund	Investment Objectives
Money Market	Maximum current income with the preservation of capital and maintenance of liquidity.
U.S. Government Securities	High level of current income and safety of principal.
Tax-Free Income	High level of current income that is exempt from federal income tax, consistent with the preservation of capital.
Minnesota Tax-Free Income	High level of current income that is exempt from federal reglar income tax and Minnesota regular personal income tax, consistent with the preservation of capital.
Florida Tax-Free Income	High level of current income that is exempt from federal regular income tax by investing in securities that are exempt from the Florida intangibles tax.

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, or when the Advisor becomes aware that a significant event impacting the value of a security or group of securities has occurred after the closing of the exchange on which the security or securities principally trade, but before the calculation of the daily net asset value, securities are valued at fair value as determined in good faith using procedures established by the Board 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.

70

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. Dividends received from closed-end fund holdings are included in Interest Income and are generated from the underlying investments.

Delivery and payment for securities which have been purchased by the Funds on a forward commitment or when-issued basis can take place two weeks or more after the transaction date. During this period, such securities are subject to market fluctuations and may increase or decrease in value prior to delivery, and the Funds maintain segregated assets with a market value greater than the amount of their purchase commitments.

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.

The Florida Tax-Free Income Fund concentrates its investments in Florida, and therefore may have more credit risk related to the economic conditions in the state of Florida 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.

As of March 31, 2005, for federal income tax purposes, some Funds have capital loss carryovers which, if not offset by subsequent gains will begin to expire as follows:

	Loss Carryover		Expiration Year
U.S. Government Securities	$	3,964,767	2007
Tax-Free Income	$	29,658,089	2008
MN Tax-Free Income	$	7,995,128	2008
FL Tax-Free Income	$	16,907	2013

      Notes to Financial Statements (continued)

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 accounting principles generally accepted in the United States of America 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.

(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 the 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:

	Average Daily Net Assets
Tax-Free Income Fund	.80%
Minnesota Tax-Free Income Fund	.80%
Florida Tax-Free Income Fund	.80%

72

	First $50 Million	Over $50 Million
Money Market Fund	.80%	.60%
U.S. Government Securities Fund	1.00%	.80%

For the period October 1, 1993, through December 31, 2006, 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, 2006, this voluntary fee waiver may be discontinued by the Adviser in its sole discretion.

     Sit Mutual Funds
      Expense Example (Unaudited)

        As a shareholder of the Funds, you incur two types of costs: (1) transaction costs, including redemption fees and (2) ongoing costs, including management fees; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Funds and to compare these costs with the ongoing costs of investing in other mutual funds.

        The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period April 1, 2005 to September 30, 2005.

Actual Expenses
        The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes
        The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

        Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as redemption fees. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs (redemption fees) were included, your costs would have been higher.
