	Chairman’s Letter

Dear fellow shareholders:

     The Federal Reserve increased short-term interest rates twice more during the second calendar quarter of 2006, bringing the federal funds rate to 5.25%. Treasury yields rose approximately 30 basis points to above 5.0% across the maturity spectrum, reflecting continued concerns over inflation and creating an almost flat yield curve. The Fed’s rate increase on June 29, 2006 was its 17^th and latest move in the 425 basis points of tightening that began two years earlier. Weaker economic data in the third quarter of 2006 led intermediate and longer term yields to decline as investors believed that the current cycle of Fed tightening might be done. Treasury yields have been relatively stable since then, with the front end of the curve inverted as short term yields remain higher than longer term yields. The 3-month Treasury bill yield ended the 12-month period 0.40% higher at around 5.0% while the 5-year and 30-year Treasury yields declined -0.27% and -0.04% to 4.54% and 4.85%, respectively. The Fed has maintained a bias against inflationary risks since its May 2006 meeting.

     The final estimate of U.S. fourth quarter 2006 real GDP growth was +2.5%, and total real GDP growth measured on a year-over-year basis in the fourth quarter remained a healthy +3.1%. We expect real GDP growth rate to moderate to a +2.7% average rate for 2007. Real personal consumption expenditures (PCE), which represent two-thirds of GDP, are on pace to exceed +3.0% for the first calendar quarter of 2007 and could approach +4.0%. While this rate of spending growth represents a slowdown from the +4.2% rate posted in the fourth quarter, it is still quite solid and counters the recession prospects that an inverted yield curve environment might suggest. The strong employment data released on April 5^th, which saw the unemployment rate dip slightly to 4.4%, was also supportive of sustained consumer spending. The domestic economy could also see strength from other sectors. The inventory sector, which is notoriously volatile and remained a major drag in the fourth quarter, could eventually rebound to provide a solid underpinning to growth. In addition, real business spend-

ing remains a positive factor and, despite some softening, grew at approximately twice the rate of the total economy on a year-over-year basis in the fourth quarter.

     The headline Consumer Price Index for All Urban Consumers (CPI) increased +0.4% in February, and core CPI, which excludes the volatile food and energy sectors, rose +0.2%. These monthly increases resulted in year-over-year figures of +2.4% and +2.7% for the headline and core CPIs, respectively. Over the next few months, the year-over-year CPI data are likely to decrease from February levels as a result of easy comparisons from the same period a year ago. However, in the second half of the year, the opposite effect will occur as even just moderate increases in the monthly inflation figures will boost the year-over-year measurements. Despite the intermediate volatility, we expect the average CPI figure for the year to fall in a range between +2.0% and +2.5%.

     Although the dollar has been weak recently, it has stayed within its trading range of the past two years. We expect the dollar to remain in this range as pressure from the budget and trade deficits is, at least partially, offset by the relative attractiveness of U.S. equity and fixed-income markets.

     The domestic fiscal environment has shown steady improvement and we continue to expect the deficit to be less than $200 billion for the current fiscal year. For the first five months of fiscal 2007 through February, the U.S. budget deficit stands at $162.2 billion, which is almost a $56 billion improvement over the $217.7 billion deficit for the comparable period last year. Receipt growth for the first half of fiscal year 2007 is estimated to have increased +8% versus the comparable period in fiscal 2006 due to higher tax payments, while outlays are estimated to have grown just +2%. Factoring in similarly positive Congressional Budget Office (CBO) estimates for March, estimates from CBO and the Office of Management and Budget (OMB) for the fiscal year 2007 budget deficit remain unchanged at $177 billion and $244 billion, respectively.

Strategy Summary

     We continue to expect that the U.S. economy will successfully transition to a more moderate growth environment, with real GDP growth averaging approximately +2.7% in 2007, as indications are that the key consumer spending sector remains intact. Elevated energy prices and a slowdown in the housing market are providing dual headwinds. Factors in the housing market, generally, and the subprime market, specifically, will continue to create pressures on consumer spending. However, we believe the bottoming phase in the housing market correction is underway and that the spillover effects from the difficulties in the subprime lending market will be manageable. While the price of crude oil rose in March, it remains well below the highs of last spring and summer and is close to flat with this period last year. Looking forward, inflation could provide a surprise on the upside later in the year as the easy comparisons from prior periods roll off. Nonetheless, we expect the CPI figure to average between +2.0% and +2.5% for the year.

     The yield curve steepened in March, reflecting increased investor anticipation of a cut in the federal funds rate later this year in response to weaker economic data. The slowing housing market and problems within the subprime mortgage market have added to the list of justifications for the Fed to reduce its hawkish stance on interest rates. The Fed dropped its tightening bias at its meeting on March 21^st, 2007 while maintaining an inflationary risk assessment. We expect further steepening in the yield curve later in the year as shorter and intermediate term rates decline while longer term yields should be relatively stable. However, longer term yields could shift slightly higher if an inflation surprise materializes and the Fed decides to maintain short term rates around current levels. Taxable bond portfolio durations are being maintained modestly longer than related benchmarks, with an emphasis on attractively yielding securities that will outperform in a steepening yield curve environment.

     Municipal issuance volume remains high. New issuance volume in calendar 2007 is estimated to be around $375 billion, compared to $383 billion in 2006 and the record $408 billion in 2005. Approximately $80 billion of issuance is expected to come from voter-approved funding measures passed in November, of which $43 billion will come from California alone. Relative yield comparisons of short to intermediate duration municipals to similar duration Treasuries have cheapened as supply has kept shorter and intermediate municipal yields from declining. For example, the ratio of 10-year maturity municipal-to-Treasury yields increased from approximately 80% to 85% in March, returning to the higher end of its historical range in recent years. Longer term municipal bonds are fairly valued when compared to taxable bonds on a relative yield basis. We expect improving underwriting profitability for insurers to help demand for municipals remain robust, despite yields remaining near historic lows. Durations on our municipal portfolios are being extended closer to their benchmark levels in anticipation of the steepening yield curve environment we expect later in 2007. We remain focused on securities that offer attractive after-tax income, but are cautious as incremental yields provided by higher yielding sectors are historically narrow.

     Fixed-income investments are an important component of a well-diversified, long term portfolio. We believe the Sit Bond Funds, with their dual objectives of high income and stability of principal, offer attractive risk/reward profiles to complement equity holdings. We appreciate your continued interest 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

Performance Summary - Bond Funds

     The Federal Reserve increased short term rates twice more on May 10th and June 29th, 2006, bringing the federal funds rate to 5.25%. The rate increase in June was the Fed’s 17th and latest move in the 425 basis points round of tightening that began two years earlier. The 3-month Treasury bill yield rose from 4.60% in March 2006 to 5.00% by June 2006 while Treasury bond yields rose approximately +0.30%, creating an almost flat yield curve. Since June, Treasury bill yields have been relatively stable while intermediate and longer term Treasury yields have fallen by approximately -0.60% and -0.35%, respectively, to create an inverted yield curve. Longer term bond yields ended the 12-month period little changed as 5-year and 30-year Treasury yields declined just - -0.27% and -0.04%, respectively, to 4.54% and 4.85% on March 31, 2007. The Fed has maintained a bias against inflationary risks since its May 2006 meeting.

     Taxable bonds provided attractive returns for the 12-month period as short-term securities earned high current income and longer term securities benefited from price appreciation resulting from the decline in yields. The corporate sector outperformed due to its longer duration, despite recent widening in yield spreads as economic growth has moderated. The mortgage sector, with its yield advantage, also outperformed. The Treasury sector lagged due to its lower yields while the asset-backed sector lagged due to its shorter duration.

     Shorter term municipals were fairly stable during the 12-month period while intermediate and longer term yields fell. Demand for municipals has remained robust despite a continued heavy pace of new issuance. The Bond Buyer 40-Bond Index yield rose to almost 5.0% in June and then declined to 4.61% to end the fiscal year-0.19% lower. As of March 31, 2007, longer term municipals were fairly valued compared to Treasury bonds on a relative yield basis while valuations on shorter and intermediate municipals were at the cheaper end of their recent historical range. The higher yielding industrial revenue and health care sectors outperformed during the period, while shorter duration municipal sectors lagged.

     Fixed-income portfolios are being positioned to take advantage of the steepening yield curve environment we expect later in 2007, and we remain focused on securities that offer attractive incremental yield.

Average Annual Total Returns for Periods Ended December 31, 2006

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, 2006. 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).

Sit Money Market Fund

One Year Ended March 31, 2007

Michael C. Brilley, Senior Portfolio Manager
Mark H. Book, CFA, Portfolio Manager

     The Sit Money Market Fund returned +4.80% net of fees for the twelve months ended March 31, 2007 compared to +5.18% for the 3-month U.S. Treasury bill. As of March 31, the Fund’s 7-day compound yield was 4.97% and its average maturity was 25 days.

     The Fed raised the federal funds rate target to 5.25% in June 2006, which was its latest increase in the tightening cycle that began two years earlier in June 2004. Short-term yields rose during the 12-month period while yields on intermediate and longer maturities declined. Yields on intermediate maturities fell the most, creating an inverted yield curve at the front end of the maturity spectrum and an upward sloping curve at the long end. Because investors in longer maturity Treasuries believe the Fed will be successful in its efforts to contain inflation, they have been willing to buy intermediate and long maturity Treasuries at lower yields. The steepening in the yield curve reflects investor anticipation of a cut in the federal funds rate later in 2007, in response to recent weaker economic data and the Federal Reserve’s decision to drop its tightening bias at its most recent FOMC meeting on March 21, 2007. While market levels currently suggest that the Fed will begin reducing rates in the third quarter of 2007, we believe that easing may not occur that soon, as the Fed is still focused on containing inflation. It is unclear when the Fed will begin easing monetary policy but action will continue to be largely dependent on various metrics including the rate of inflation and economic growth.

     The Fund has maintained its average maturity near the short end of its customary 20 to 40 day range as the 3-month Treasury bill yield increased 43 basis points over the past twelve months. The Fund has begun to extend its average maturity as the current cycle of Fed tightening may be complete. Corporate credit quality remains strong in general, but some sectors have slowed along with the economy. The Fund has no direct exposure to sub-prime mortgages, which has become a concern in the Corporate market. We continue to focus on issuers 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.

Sit U.S. Government Securities Fund

One Year Ended March 31, 2007

Senior Portfolio Managers, Michael C. Brilley and Bryce A. Doty, CFA
Portfolio Manager, Mark H. Book, CFA

     The Sit U.S. Government Securities Fund returned +5.81% during the fiscal year ending March 31, 2007, compared to the return of the Lehman Intermediate Government Bond Index of +5.75%. The Fund’s 30-day SEC yield was 4.98% and its 12-month distribution rate was 4.61%.

     The return for the Fund was most positively influenced by its holdings in collateralized mortgage obligations, which exceeded the returns of the Lehman Intermediate Government Bond Index due to their income advantage. The Fund’s weighting in U.S. Treasury obligations detracted from performance, as these securities did not experience price appreciation in line with the bond market as a whole.

     The last twelve months experienced two raises by the Federal Reserve in its target short-term lending rate to a level of 5.25%, each occurring in the first two meetings of the fiscal year, May 10^th and June 29^th. Mid-year 2006, the Federal Reserve ended its consistent tightening pace as inflation came to a more measured level. The Federal Reserve is still mindful of inflation risk, while monitoring the potential for an economic slowdown. We believe a decrease in the Federal Reserve’s short term borrowing rate sometime in the second half of the year is likely, as concern of slower economic growth builds. However, we believe that fears of higher inflation will potentially result in higher yields and price depreciation for longer maturity fixed income securities. As such, we expect the price stability of the Fund’s high coupon mortgage securities, coupled with their high level of income, to drive the Fund’s return, which has consistently been the case since the Fund’s inception.

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).

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 Intermediate Government Bond Index. The Lipper returns are obtained from Lipper Analytical Services, Inc., a large independent evaluator of mutual funds.

(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.

GROWTH OF $10,000

The sum of $10,000 invested at inception (6/2/87) and held until 3/31/07 would have grown to $35,656 in the Fund or $36,664 in the Lehman Intermediate Government Bond Index assuming reinvestment of all dividends and capital gains.

Sit Tax-Free Income Fund

One Year Ended March 31, 2007

Senior Portfolio Managers
Michael C. Brilley • Debra A. Sit, CFA • Paul J. Jungquist, CFA

     The Sit Tax-Free Income Fund returned +4.00% for the fiscal year ended March 31, 2007, compared with a return of +4.28% for the Lehman 5-year Municipal Bond Index. The Fund’s 30-day SEC yield was 4.29% and its 12-month distribution rate was 3.93% as of March 31, 2007.

     The Federal Reserve last raised its federal funds target rate in late June 2006. With short term rates unchanged since mid 2006, intermediate term bond yields have fallen over the past twelve months. This period of relative stability followed several prior years of rising intermediate term yields as the Federal Reserve increased its federal funds target rate from 1.0% to 5.25%. We expect short and intermediate term yields to be relatively stable until late 2007, when slowing economic growth could cause somewhat lower yields unless inflationary pressures force the Federal Reserve to increase short-term interest rate levels.

     The Fund invests in six different market sectors that each account for more than 5% of its holdings. Five of these sectors earned returns that exceeded the return of the Lehman 5-Year Municipal Bond Index. Only the multi-family housing sector underperformed that index, as bond prices fell, reflecting the continued trend of rating reductions by the bond rating agencies due to the difficulties of raising rents and higher than historic vacancy levels.

     We expect the Federal Reserve to maintain short-term rates at their current level for the next six months. Economic growth is expected to be in the +2% to +3% range and inflation to moderate during the second half of 2007. Bond yields are expected to remain relatively stable until late in the year when the yield curve is expected to steepen.

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 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 3/31/07 would have grown to $28,663 in the Fund or $28,278 in the Lehman 5-Year Municipal Bond Index assuming reinvestment of all dividends and capital gains.

Sit Minnesota Tax-Free Income Fund

One Year Ended March 31, 2007

Senior Portfolio Managers
Michael C. Brilley • Debra A. Sit, CFA • Paul J. Jungquist, CFA

     The Minnesota Tax Free Income Fund returned +5.17% over the past twelve months compared to +4.28% for the Lehman 5-Year Municipal Bond Index. The Fund’s 30-day SEC yield was 4.34% as of March 31, 2007 and its 12-month distribution rate was 4.17%. The Fund’s taxable equivalent yield of 7.25% for investors in the highest state and federal tax brackets compares favorably to taxable fixed-income alternatives.

     During the 12-month period, short-term Treasury rates rose, with intermediate rates declining approximately 0.25% and the 30-year Treasury down just 0.04%. The Federal Reserve has left the federal funds rate target unchanged at 5.25% since its latest increase in June 2006. It appears likely that the Fed has completed its tightening cycle, and the market expects that the Fed will cut its rate target later this year.

     The municipal yield curve flattened during the period but remains positively sloped. Over the past 12-month period, municipal yields fell 9 basis points for 1-year maturities and approximately 18 to 33 basis points for maturities in the 5-year to 30-year range. The decline in rates resulted in price appreciation across all maturities, with longer maturities exhibiting the greatest increases in price and the highest returns.

     The Fund’s largest sector holdings are in hospital/health-care, multifamily housing, and education issues. These sectors each earned significantly higher returns than the benchmark Index. The primary factors affecting returns over the 12-month period were the Fund’s yield advantage, security selection, and strong price performance, which was due to both the dearth of supply of Minnesota issues with higher yields as well as the Fund’s longer duration relative to its benchmark.

     The market currently expects the Fed to begin cutting the federal funds rate target by the end of the third quarter. However, we believe rate cuts would only materialize if inflation is contained and that they may not occur as early as the market expects. The municipal market should be fairly stable over the near term. We plan to maintain the Fund’s duration close to its benchmark, or perhaps modestly lengthen, in light of our expectations for a steeper yield curve and possible rate cuts late in the 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 3/31/07.	**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 3/31/07 would have grown to $19,607 in the Fund or $18,611 in the Lehman 5-Year Municipal Bond Index assuming reinvestment of all dividends and capital gains.

Sit Florida Tax-Free Income Fund

One Year Ended March 31, 2007

Senior Portfolio Managers
Michael C. Brilley • Debra A. Sit, CFA • Paul J. Jungquist, CFA

     The Sit Florida Tax-Free Income Fund provided a return of +3.97% net of fees for the twelve months ended March 31, 2007, compared with a return of +4.28% for the Lehman 5-Year Municipal Bond Index. The Fund’s 30-day SEC yield was 4.05% and its 12-month distribution rate was 3.60%.

     Municipal bond yields fell slightly over the past 12 month period, with yields on intermediate and longer maturities down more than yields on short maturities. The yield curve flattened during the year, but remains positively sloping. Interest rates declined as economic growth began to slow, and the Federal Reserve has held short-term interest rates steady since its latest increase in June 2006. While the Federal Reserve remains focused on containing inflation, the market is anticipating a cut in the targeted rate later this year.

     The Fund’s investment returns from the hospital/health-care, multi-family housing and other revenue sectors outperformed the Lehman 5-Year Municipal Index, with the hospital sector providing the greatest incremental return. The Fund’s duration remained shorter than the Lehman 5-Year Index as it has since the inception of the Fund. That shorter duration has been the primary factor contributing to the Fund’s underperformance relative to the benchmark index. The Fund remains focused on providing attractive tax exempt income and relative stability of principal.

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 Lip-per 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 3/31/07 would have grown to $11,082 in the Fund or $10,816 in the Lehman 5-Year Municipal Bond Index assuming reinvestment of all dividends and capital gains.

Summary of Significant Accounting Policies

The Sit Mutual Funds (the Funds) are 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 Objective
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 regular 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 Adviser 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. As of March 31, 2007, the Tax-Free Income and Minnesota Tax-Free Income Funds entered into when-issued or forward commitments valued at $3,405,068 and $560,980, respectively.

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.

Line of Credit

The Funds have a $25,000,000 committed line of credit through PNC Bank, N.A., whereby the Funds may borrow for the temporary funding of shareholder redemptions or for other temporary purposes. Interest is charged to each Fund based on its borrowings at a rate equal to the Federal Funds Rate plus fifty basis points (0.50%). The Funds had no borrowings outstanding during the year ended March 31, 2007.

Recent Accounting Pronouncements

On September 20, 2006, the Financial Accounting Standards Board (FASB) released Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (SFAS 157). SFAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of SFAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The impact of SFAS 157 on the Fund’s financial statements is being evaluated.

In June 2006, the FASB issued FASB Interpretation 48 (FIN 48), “Accounting for Uncertainty in Income Taxes.” FIN 48 clarifies the accounting for uncertainty in income taxes recognized in accordance with FASB Statement No. 109, “Accounting for Income Taxes.” FIN 48 prescribes a two-step process to recognize and measure a tax position taken or expected to be taken in a tax return. The first step is to determine whether a tax position has met the more-likely-than-not recognition threshold and the second step is to measure a tax position that meets the threshold to determine the amount of benefit to recognize. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006. Tax positions of the Funds are being evaluated to determine the impact, if any, to the Funds. The adoption of FIN 48 is not anticipated to have a material impact on the Funds.

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. The tax character of distributions paid during the fiscal years ended March 31, 2007 were as follows:

Year Ended March 31, 2007:
	Ordinary Income			Long Term Capital Gain				Total
Money Market		$	3,045,336	—					$	3,045,336
U.S. Government Securities		$	9,805,228	—					$	9,805,228

As of March 31, 2007, the components of distributable earnings on a tax basis were as follows:
	Undistributed Ordinary Income			Accumulated Gain (Loss)				Unrealized Appreciation (Depreciation)
Money Market		$	198,293			—				—
U.S. Government Securities		$	785,815		($	3,820,689	)		($	1,152,985	)

FL Tax-Free Income		$	11,529		($	15,252	)		$	9,839

On the statement of assets and liabilities for the U.S. Government Securities Fund, as a result of permanent book-to-tax differences, a reclassification adjustment of $419,268 was made to decrease additional paid-in capital and increase accumulated net realized gain (loss).

As of March 31, 2007, 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		$	3,820,689	2008
Tax-Free Income		$	28,739,071	2008
MN Tax-Free Income		$	9,665,582	2008
FL Tax-Free Income		$	15,252	2013

	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 U.S. 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.
(2)	Investment Security Transactions
	The cost of purchases of and proceeds from sales and maturities of investment securities, other than short-term securities, for the period ended March 31, 2007, were as follows:

	Purchases ($)	Proceeds ($)
U.S. Government Securities Fund	92,417,493	130,271,746

Minnesota Tax-Free Income Fund	101,356,304	77,568,639

(3)	Expenses

(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

We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of Sit Money Market Fund, Inc., Sit U.S. Government Securities Fund, Inc., Sit Tax-Free Income Fund (a series of Sit Mutual Funds II, Inc.), Sit Minnesota Tax-Free Income Fund (a series of Sit Mutual Funds II, Inc.), and Sit Florida Tax-Free Income Fund (a series of Sit Mutual Funds Trust) (the “Funds”), as of March 31, 2007, and 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 for each of the years or periods in the five-year period then ended. These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of March 31, 2007, by correspondence with the custodian and brokers or by other appropriate auditing procedures. 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 Tax-Free Income Fund, Sit Minnesota Tax-Free Income Fund, and Sit Florida Tax-Free Income Fund as of March 31, 2007, and the results of their operations for the year then ended, the changes in their net assets for each of the years in the two-year period then ended, and their financial highlights for each of the years or periods in the five-year period then ended, in conformity with U.S. generally accepted accounting principles.

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 October 1, 2006 to March 31, 2007.

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.

RE-APPROVAL OF INVESTMENT MANAGEMENT AGREEMENTS

At their joint meeting held on October 23, 2006 the Boards of Directors of the Sit Mutual Funds unanimously approved the continuation for another one year period of the investment management agreements entered into by and between Sit Investment Associates, Inc. (“SIA”) and Sit Mutual Funds II, Inc. dated November 1, 1992; Sit U.S. Government Securities Fund, Inc. dated November 1, 1992; Sit Money Market Fund, Inc. dated November 1, 1992; and Sit Mutual Funds Trust dated December 15, 2003 (the “Advisory Agreements”).

The Boards approved the Agreements after a lengthy discussion and consideration of various factors relating to both the Boards’ selection of SIA as the investment adviser and the Boards’ approval of the fees to be paid under the Agreements.

Investment Adviser Criteria. The Directors began their analysis by discussing their criteria for determining the quality of an investment adviser. The Directors’ noted that their analysis is similar to that used by institutional investors in evaluating and selecting investment advisers. The Directors discussed several factors used to determine the overall quality of an investment adviser, including the following:

Investment Philosophy and Process. The Directors considered SIA’s philosophy of managing assets. With respect to fixed income securities, SIA stresses the consistent attainment of superior risk-adjusted returns using a conservative investment management approach that identifies pricing anomalies in the market and management of portfolio duration.

With respect to fixed income securities, SIA seeks investment grade securities with a special emphasis on interest

Additional Information (Continued)

income and significant stability of principal value. SIA’s style seeks to avoid excessive return volatility and generate consistent results over an economic cycle. The Directors noted that the Bond Funds’ objectives are to seek high current income. The Directors reviewed the Bond Funds’ characteristics, and noted that SIA has consistently managed the Bond Funds in this style. The Directors noted that since the Bond Funds emphasize income, they may at times not rank highly in total return comparisons with other funds during certain periods.

The Directors discussed SIA’s consistent and well-defined investment process. With respect to fixed income securities, the portfolio managers are responsible for implementing the strategy set forth in the Chief Fixed Income Officer’s duration targets and the Chief Investment Officer’s interest rate projections.

Investment Professionals. The Directors discussed the experience, knowledge and organizational stability of SIA and its investment professionals. The Directors noted that SIA’s senior founding professionals are actively involved in the investment process and have led the organization since its inception in 1981 which has provided not only organizational stability, but a consistent portfolio management style. The senior professionals of SIA are among the most experienced professionals in the industry.

The Directors discussed the depth of SIA’s investment staff. The Directors noted that SIA has over 30 investment professionals. Given the investment products offered by SIA and the assets under management, the Directors determined that SIA’s investment staff is well positioned to meet the current needs of its clients, including the Funds, and to accommodate growth in the number of clients and assets under management for the near future. The Directors concluded that the depth of the investment staff, and in particular senior management and investment analysts, is actually greater than the Funds currently require at their present asset size. The Directors noted that SIA has the resources of a $6.9 billion investment firm working for the benefit of the Fund shareholders.

Investment Performance. The Directors reviewed and discussed the Funds’ investment performance on an absolute and comparable basis for various periods as discussed below. The Directors noted that the investment performance of the Funds has generally been competitive with indices and other funds with similar investment styles as the Funds, such as fixed income funds seeking to maximize income.

Corporate Culture. The Directors discussed SIA’s corporate values to operate under the highest ethical and professional standards. SIA’s culture is set and practiced by senior management who insist that all professionals exhibit honesty and integrity. The Board noted that the firm’s values are evident in all of the services provided to the Funds.

Review of Specific Factors. The Directors continued their analysis by reviewing specific information on SIA and the Funds and specific terms of the Agreements, including the following.

Investment Performance. The Directors reviewed investment performance of each Fund for 1 month, 3 months, 6 months, year-to-date, 1 year, 5 years (as applicable), 10 years (as applicable) and since inception, both on an absolute basis and on a comparative basis to indices and mutual funds within the same investment categories. As noted above, the Directors concluded that the investment performance of the Funds has been competitive in relation to their stated objectives and strategies on a comparable basis with funds with similar objectives and strategies.

90

Fees and Expenses. The Directors noted that the Funds pay SIA a monthly fee and SIA is responsible for all of the Funds’ expenses except interest, brokerage commissions and transaction charges and certain extraordinary expenses. The Directors reviewed fees paid in prior years and the fees to be paid under the Agreements, both before and after the voluntary waiver of fees by SIA with respect to the Tax-Free Income Fund, U.S. Government Fund and Money Market Fund. The Directors reviewed the average and median expense ratios of mutual funds within the same investment category for each Fund. The Directors noted that each Fund’s total expense ratio compares favorably to the total expense ratios of other no-load funds within the Fund’s Morningstar category, and are lower than the average total expense ratio for the full Morningstar category. The Directors concluded that the fees paid by the Funds are reasonable and appropriate.

The Directors reviewed the extent to which the fees to be paid under the Agreements by each Fund may be affected by an increase in the Fund’s assets, which included reviewing each Fund’s current and historical assets and the likelihood and magnitude of future increases in the Fund’s assets. It was noted that three of the fixed-income funds have tiered investment fee schedules after SIA’s voluntary fee waiver. The Directors agreed that it is appropriate that the Funds benefit from improved economies of scale as the Funds’ assets increase. However, the Directors concluded that given the limited size of the Funds, negotiating a graduated fee structure for each Fund is unnecessary since it is unlikely that the size of the Funds will increase enough to justify a graduated fee schedule within the near future.

The Directors reviewed the expenses paid by SIA relating to the operations of the Funds, and SIA’s income with respect to the management of the Funds for the past two calendar years. The Directors concluded that the expenses paid were appropriate.

The Directors reviewed SIA’s investment advisory fee schedule for investment management services provided to other clients. The Directors compared the services provided to the Funds and other clients of SIA, and recognized that the Funds’ expenses are borne by SIA. The Directors concluded that the fees paid by the Funds in relation to the fees paid by other SIA clients were appropriate and reasonable. The Directors also concluded that SIA’s profit margin with respect to the management of the Funds was appropriate.

The Directors discussed the extent to which SIA receives benefits from the relationship with the Funds such as soft dollar arrangements by which brokers provide research services to SIA as a result of brokerage generated by the Funds. The Board concluded that any benefits SIA receives from its relationship with the Funds are well within industry norms and are reflected in the amount of the fees paid by the Funds to SIA and are appropriate and reasonable.

Non-Advisory Services. The Directors considered the quality of non-advisory services which SIA provides to the Funds (and their shareholders) and the quality and depth of SIA’s non-investment personnel who provide such services. Directors concluded that the level of such services and the quality and depth of such personnel are consistent with industry standards.

Finally, the Directors considered the compliance staff and the regulatory history of SIA and the Funds, and concluded that both are consistent with industry standards.

Chairman’s Letter – Period Ended March 31, 2007

Dear fellow shareholders:

          The Federal Reserve increased short-term interest rates twice more during the second calendar quarter of 2006, bringing the federal funds rate to 5.25%. Treasury yields rose approximately 30 basis points to above 5.0% across the maturity spectrum, reflecting continued concerns over inflation and creating an almost flat yield curve. The Fed’s rate increase on June 29, 2006 was its 17^th and latest move in the 425 basis points of tightening that began two years earlier. Weaker economic data in the third quarter of 2006 led intermediate and longer term yields to decline as investors believed that the current cycle of Fed tightening might be done. Treasury yields have been relatively stable since then, with the front end of the curve inverted as short term yields remain higher than longer term yields. The 3-month Treasury bill yield ended the 12-month period 0.40% higher at around 5.0% while the 5-year and 30-year Treasury yields declined -0.27% and -0.04% to 4.54% and 4.85%, respectively. The Fed has maintained a bias against inflationary risks since its May 2006 meeting.

          The final estimate of U.S. fourth quarter 2006 real GDP growth was +2.5%, and total real GDP growth measured on a year-over-year basis in the fourth quarter remained a healthy +3.1%. We expect real GDP growth rate to moderate to a +2.7% average rate for 2007. Real personal consumption expenditures (PCE), which represent two-thirds of GDP, are on pace to exceed +3.0% for the first calendar quarter of 2007 and could approach +4.0%. While this rate of spending growth represents a slowdown from the +4.2% rate posted in the fourth quarter, it is still quite solid and counters the recession prospects that an inverted yield curve environment might suggest. The strong employment data released on April 5^th, which saw the unemployment rate dip slightly to 4.4%, was also supportive of sustained consumer spending. The domestic economy could also see strength from other sectors. The inventory sector, which is notoriously volatile and remained a major drag in the fourth quarter, could eventually rebound to provide a solid underpinning to growth. In addition, real business spending remains a positive factor and, despite some softening, grew at approximately twice the rate of the total economy on a year-over-year basis in the fourth quarter.

          The headline Consumer Price Index for All Urban Consumers (CPI) increased +0.4% in February, and core CPI, which excludes the volatile food and energy sectors, rose +0.2%. These monthly increases resulted in year-over-year figures of +2.4% and +2.7% for the headline and core CPIs, respectively. Over the next few months, the year-over-year CPI data are likely to decrease from February levels as a result of easy comparisons from the same period a year ago. However, in the second half of the year, the opposite effect will occur as even just moderate increases in the monthly inflation figures will boost the year-over-year measurements. Despite the intermediate volatility, we expect the

average CPI figure for the year to fall in a range between +2.0% and +2.5%.

          Although the dollar has been weak recently, it has stayed within its trading range of the past two years. We expect the dollar to remain in this range as pressure from the budget and trade deficits is, at least partially, offset by the relative attractiveness of U.S. equity and fixed-income markets.

          The domestic fiscal environment has shown steady improvement and we continue to expect the deficit to be less than $200 billion for the current fiscal year. For the first five months of fiscal 2007 through February, the U.S. budget deficit stands at $162.2 billion, which is almost a $56 billion improvement over the $217.7 billion deficit for the comparable period last year. Receipt growth for the first half of fiscal year 2007 is estimated to have increased +8% versus the comparable period in fiscal 2006 due to higher tax payments, while outlays are estimated to have grown just +2%. Factoring in similarly positive Congressional Budget Office (CBO) estimates for March, estimates from CBO and the Office of Management and Budget (OMB) for the fiscal year 2007 budget deficit remain unchanged at $177 billion and $244 billion, respectively.

Strategy Summary

          We continue to expect that the U.S. economy will successfully transition to a more moderate growth environment, with real GDP growth averaging approximately +2.7% in 2007, as indications are that the key consumer spending sector remains intact. Elevated energy prices and a slowdown in the housing market are providing dual headwinds. Factors in the housing market, generally, and the subprime market, specifically, will continue to create pressures on consumer spending. However, we believe the bottoming phase in the housing market correction is underway and that the spill-over effects from the difficulties in the subprime lending market will be manageable. While the price of crude oil rose in March, it remains well below the highs of last spring and summer and is close to flat with this period last year. Looking forward, inflation could provide a surprise on the upside later in the year as the easy comparisons from prior periods roll off. Nonetheless, we expect the CPI figure to average between +2.0% and +2.5% for the year.

          The yield curve steepened in March, reflecting increased investor anticipation of a cut in the federal funds rate later this year in response to weaker economic data. The slowing housing market and problems within the subprime mortgage market have added to the list of justifications for the Fed to reduce its hawkish stance on interest rates. The Fed dropped its tightening bias at its meeting on March 21^st, 2007 while maintaining an inflationary risk assessment. We expect further steepening in the yield curve later in the year as shorter and intermediate term rates decline while longer term yields should be relatively stable. However,

2

longer term yields could shift slightly higher if an inflation surprise materializes and the Fed decides to maintain short term rates around current levels. Taxable bond portfolio durations are being maintained modestly longer than related benchmarks, with an emphasis on attractively yielding securities that will outperform in a steepening yield curve environment.

          Municipal issuance volume remains high. New issuance volume in calendar 2007 is estimated to be around $375 billion, compared to $383 billion in 2006 and the record $408 billion in 2005. Approximately $80 billion of issuance is expected to come from voter-approved funding measures passed in November, of which $43 billion will come from California alone. Relative yield comparisons of short to intermediate duration municipals to similar duration Treasuries have cheapened as supply has kept shorter and intermediate municipal yields from declining. For example, the ratio of 10-year maturity municipal-to-Treasury yields increased from approximately 80% to 85% in March, returning to the higher end of its historical range in recent years. Longer term municipal bonds are fairly valued when compared to taxable bonds on a relative yield basis. We expect improving underwriting profitability for insurers to help demand for municipals remain robust, despite yields remaining near historic lows. Durations on our municipal portfolios are being extended closer to their benchmark levels in anticipation of the steepening yield curve environment we expect later in 2007. We remain focused on securities that offer attractive after-tax income, but are cautious as incremental yields provided by higher yielding sectors are historically narrow.

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

With best wishes,

Sit High Income Municipal Bond Fund

Three Months Ended March 31, 2007

Portfolio Managers
Michael C. Brilley • Debra A. Sit, CFA • Paul J. Jungquist, CFA • Andrew T. Clark, CFA

          The Fund made its inception December 31, 2006. The Fund provided investors with a +0.90% total return for the quarter ended March 31, 2007 compared to a +0.80% return for the Lehman Municipal Bond Index. As of March 31, 2007, the Fund’s 30-day SEC yield was 3.56%.

          Municipal bond yields increased slightly during the quarter, primarily as a result of continued heavy supply. Municipal issuance totaled slightly more than $100 billion in the quarter, an increase of 49% over the first quarter of 2006. Issuance is expected to remain heavy throughout 2007. While it appears that the Fed is close to or done for this tightening cycle, the interest rate environment could remain challenging for the remainder of the year, as the timing and direction of the Fed’s next move is still unclear. The Fund’s net asset value was remarkably stable during the quarter, rising from $10.00 at December 31, 2006 to $10.01 at March 31, 2007. The Fund experienced an increase in net assets over the quarter to $9.5 million.

          The Fund’s most significant investments during the quarter were in the multi-family housing (primarily senior living) sector, the healthcare (primarily hospitals) sector, the education (primarily charter schools) sector, and the other revenue (primarily land-secured) sector. The Fund will maintain significant weightings in these sectors going forward, but the weightings should decrease somewhat as the Fund grows and becomes more diversified. Forty-one credits (half of which were rated) in twenty-one states were held in the Fund as of March 31. The Fund’s overall weighted credit quality is BBB.

          We have lengthened the Fund’s average life duration close to 4.0 years since its inception. When it becomes clear the Fed is ready to begin easing, perhaps later this year, we anticipate that we will lengthen duration to lock in higher yields for the Fund. Demand should remain strong for lower-rated and non-rated bonds as investors reach for yield in this historically low interest rate environment, which should benefit the Fund’s performance. The Fund will likely see a significant increase in emphasis on non-rated credits in the coming year as it grows and diversifies.

INVESTMENT OBJECTIVE AND STRATEGY

          The Fund seeks high current income that is exempt from federal regular income 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. 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.

Performance is historical and assumes reinvestment of all dividends and capital gains. 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 Lehman Muni Bond Index.

(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 (12/31/06) and held until 3/31/07 would have grown to $10,090 in the Fund or $10,080 in the Lehman Municipal Bond Index assuming reinvestment of all dividends and capital gains.

Sit High Income Municipal Bond Fund

Notes to Financial Statements

(1)	Summary of Significant Accounting Policies
	The Sit High Income Municipal Bond Fund (the Fund) is a no-load fund, and is registered under the Investment Company Act of 1940 (as amended) as a diversified, open-end management investment company, or series thereof. The Fund is a series fund of Sit Mutual Funds II, Inc. The Fund has 10 billion authorized shares of capital stock that have a par value of $0.001. The Fund offers its shares in two classes: Class I and Class U. For the period ended March 31, 2007, only Class I shares were active. Accordingly, all information in this document pertains to the Class I shares. The Fund’s objective is to seek high current income that is exempt from regular income tax.
	Significant accounting policies followed by the Fund are summarized below:
	Investments in Securities
	Securities maturing more than 60 days from the valuation date, 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 Adviser 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.
	Security transactions are accounted for on the date the securities are purchased or sold. Gains and losses are calculated on the first in – first out basis. Interest, including level-yield amortization of long-term bond premium and discount, is recorded on the accrual basis.
	Delivery and payment for securities which have been purchased by the Fund 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. As of March 31, 2007, the Fund entered into when-issued or forward commitments valued at $1,124,345.
	Line of Credit
	The Fund has a $25,000,000 committed line of credit through PNC Bank, N.A., whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary purposes. Interest is charged to the Fund based on its borrowings at a rate equal to the Federal Funds Rate plus fifty basis points (0.50%). The Fund had no borrowings outstanding during the period ended March 31, 2007.
	Recent Accounting Pronouncements
	On September 20, 2006, the Financial Accounting Standards Board (FASB) released Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (SFAS 157). SFAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of SFAS 157 is required for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The impact of SFAS 157 on the Fund’s financial statements is being evaluated.
	In June 2006, the FASB issued FASB Interpretation 48 (FIN 48), “Accounting for Uncertainty in Income Taxes.” FIN 48 clarifies the accounting for uncertainty in income taxes recognized in accordance with FASB Statement No. 109, “Accounting for Income Taxes.” FIN 48 prescribes a two-step process to recognize and measure a tax position taken or expected to be taken in a tax return. The first step is to determine whether a tax position has met the more-likely-than-not recognition threshold and the second step is to measure a tax position that meets the threshold to determine the amount of benefit to recognize. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006. Tax positions of the Fund are being evaluated to determine the impact, if any, to the Fund. The adoption of FIN 48 is not anticipated to have a material impact on the Fund.
	Federal Taxes
	The Fund’s 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 Fund will distribute substantially all of its net investment income and net realized gains on a calendar year basis.

12

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. The tax character of distributions paid during the fiscal period ended March 31, 2007 were as follows:

Period Ended March 31, 2007:

Ordinary Income	Long Term Capital Gain	Total
$33,347 (*)	-----	$33,347

(*) 100% of dividends were derived from interest on tax-exempt securities.

As of March 31, 2007, the components of distributable earnings on a tax basis were as follows:

Undistributed Ordinary Income	Accumulated Gain (Loss)	Unrealized Appreciation (Depreciation)
$21,147	-----	($940)

	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 Fund’s capital stock. Distributions from net investment income are declared daily and paid monthly for the Fund. Distributions from net realized gains, if any, will be made annually for the Fund.
	Use of Estimates
	The preparation of financial statements in conformity with U.S. 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.
(2)	Investment Security Transactions
	The cost of purchases and proceeds from sales and maturities of investment securities, other than short-term securities, for the period ended March 31, 2007, were as follows:

Purchases ($)	Proceeds ($)
6,943,503	------

(3)	Expenses
	Investment Adviser
	The Fund has entered into an investment management agreement with Sit Investment Associates Inc. (SIA), under which SIA manages the Fund’s assets and provides research, statistical and advisory services, and pays related office rental, executive expenses and executive salaries. The fee for investment management and advisory services is based on the average daily net assets of the Fund at the annual rate of 0.60%. The Fund is obligated to pay all of its other operating expenses (including, but not limited to, custody, regulatory, and fund administration fees). Effective with the inception of the Fund (December 31, 2006) through December 31, 2007, the Adviser will voluntarily waive fees and reimburse other Fund expenses so that total operating expenses, after waiver, do not exceed 0.85% of average daily net assets. Amounts waived by the Adviser as described in the statement of operations are for the first three months of operation of the Fund. The 0.85% expense limitation is determined on an annual basis and therefore these amounts may be recovered by the Adviser over the remainder of the calendar year. Fee waivers may be modified or discontinued at any time after December 31, 2007 with the approval of the Board of Directors without further notice to investors.
	Transactions with affiliates
	The investment adviser, affiliates of the investment adviser, directors and officers of the Fund as a whole owned 22,149 shares of the Fund as of March 31, 2007, which represented 2.3% of all shares outstanding.

(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)	Adjusted to an annual rate. Total Fund expenses are contractually limited to .85% of average daily net assets. However, during the period ended March 31, 2007, the investment adviser voluntarily absorbed 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 4.69% for this period, and the ratio of net investment income (loss) to average daily net assets would have been (0.66%).
(3)	In addition to fees and expenses which the Fund bears directly, the Fund indirectly bears a pro rata share of the fees and expenses of the acquired funds in which it invests. Such indirect expenses are not included in the above reported expense ratios.

Report of Independent Registered
Public Accounting Firm

The Board of Directors and Shareholders
Sit Mutual Funds II, Inc.

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Sit High Income Municipal Bond Fund (a series of Sit Mutual Funds II, Inc.) (the “Fund”), as of March 31, 2007, and the related statements of operations, changes in net assets, and the financial highlights for the period from December 31, 2006 (when shares became publicly available) to March 31, 2007. These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of March 31, 2007, by correspondence with the custodian and brokers or by other appropriate auditing procedures. 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 High Income Municipal Bond Fund as of March 31, 2007, and the results of its operations, the changes in its net assets, and the financial highlights for the period from December 31, 2006 (when shares became publicly available) to March 31, 2007, in conformity with U.S. generally accepted accounting principles.

Sit High Income Municipal Bond Fund

Expense Example (Unaudited)

          As a shareholder of the Fund, 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 December 31, 2006 to March 31, 2007.

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.

	Beginning	Ending	Expenses Paid
	Account Value	Account Value	During Period*
Sit High Income Muni Bond Fund	(12/31/06)	(3/31/07)	(12/31/06 - 3/31/07)
Actual	$1,000	$1,009.00	$2.11
Hypothetical (5% return before expenses)	$1,000	$1,008.25	$2.10

* Expenses are equal to the Fund’s annualized expense ratio of 0.85%, multiplied by the average account value over the period, multiplied by 90/365 (to reflect the one-quarter year period.)

APPROVAL OF INVESTMENT MANAGEMENT AGREEMENT

At their meeting held on October 23, 2006 the Board of Directors of Sit Mutual Funds II, Inc. unanimously approved the investment management agreement entered into by and between Sit Investment Associates, Inc. (“SIA”) and Sit Mutual Funds II, Inc. (the “Advisory Agreement”) with respect to the management of the Fund. The Board approved the Advisory Agreement after a lengthy discussion and consideration of various factors relating to both the Board’s selection of SIA as the investment adviser and the Board’s approval of the fee to be paid under the Agreement.

Investment Adviser Criteria. The Directors began their analysis by discussing their criteria for determining the quality of an investment adviser. The Directors’ noted that their analysis is similar to that used by institutional investors in evaluating and selecting investment advisers. The Directors discussed several factors used to determine the overall quality of an investment adviser, including the following:

Investment Philosophy and Process. The Directors considered SIA’s philosophy of managing assets. With respect to fixed income securities generally, SIA stresses the consistent attainment of superior risk-adjusted returns using a conservative investment management approach that identifies pricing anomalies in the market and management of portfolio duration. SIA seeks securities with a special emphasis on interest income and significant stability of principal value. SIA’s style seeks to avoid excessive return volatility and generate consistent results over an economic cycle. The Directors noted that the Fund invests primarily in municipal securities that are not rated by a nationally recognized statistical rating organization, and may invest up to 60% of its assets in municipal securities rated below investment-grade.

The Directors discussed SIA’s consistent and well-defined investment process. The fixed income portfolio managers are responsible for implementing the strategy set forth in the Chief Fixed Income Officer’s duration targets and the Chief Investment Officer’s interest rate projections.

Investment Professionals. The Directors discussed the experience, knowledge and organizational stability of SIA and its investment professionals. The Directors noted that SIA’s senior founding professionals are actively involved in the investment process and have led the organization since its inception in 1981 which has provided not only organizational stability, but a consistent portfolio management style. The senior professionals of SIA are among the most experienced professionals in the industry.

The Directors discussed the depth of SIA’s investment staff. The Directors noted that SIA has over 30 investment professionals. Given the investment products offered by SIA and the assets under management, the Directors determined that SIA’s investment staff is well positioned to meet the current needs of its clients, including the Fund, and to accommodate growth in the number of clients and assets under management for the near future. The Directors concluded that the depth of the investment staff, and in particular senior management and investment analysts, is actually greater than the Fund currently requires at its present asset size. The Directors noted that SIA has the resources of a $6.6 billion investment firm working for the benefit of the Fund shareholders.

20

Investment Performance. The Fund’s inception was December 31, 2006, and therefore there was no investment performance information to review for the Fund at the Directors’ October 23, 2006 meeting. The Directors reviewed and discussed the investment performance of each of the Sit Mutual Funds and determined that performance of the fixed income funds has generally been competitive with indices and other funds with similar investment styles as the Sit Funds, such as fixed income funds seeking to maximize income.

Corporate Culture. The Directors discussed SIA’s corporate values to operate under the highest ethical and professional standards. SIA’s culture is set and practiced by senior management who insist that all professionals exhibit honesty and integrity. The Board noted that the firm’s values are evident in all of the services provided to the Fund.

Review of Specific Factors. The Directors continued their analysis by reviewing specific information on SIA and the Fund and specific terms of the Advisory Agreement, including the following:

Investment Performance. The Directors reviewed the investment performance of each of the Sit Mutual Funds for 1 month, 3 months, 6 months, year-to-date, 1 year, 5 years (as applicable), 10 years (as applicable) and since inception, both on an absolute basis and on a comparative basis to indices and mutual funds within the same investment categories. As noted above, the Directors concluded that the investment performance of the Sit fixed income funds has been competitive in relation to their stated objectives and strategies on a comparable basis with funds with similar objectives and strategies.

Fees and Expenses. The Directors noted that the Fund will pay SIA a fee for its services equal to .60% per year of the Fund’s average daily net assets, and that the Fund shall bear all of its expenses. The Directors reviewed the average and median expense ratios of mutual funds within the same investment category of the Fund. The Directors noted that the Fund’s estimated total expense ratio based on projected levels of total Fund assets, and including the servicing fee paid to a third party intermediary through which Class U shares are purchased, compares favorably to the total expense ratios of other no-load funds within the Fund’s Morningstar category. The Directors concluded that the fee set for the Fund is reasonable and appropriate. The Directors noted that through December 31, 2007, SIA will voluntarily waive fees and reimburse other Fund expenses so that total operating expenses, after waiver, do not exceed 0.85% and 1.00% of average daily net assets, for Class I and Class U shares respectively.

The Directors reviewed SIA’s investment advisory fee schedule for investment management services provided to other clients. The Directors compared the services provided to the Fund and other clients of SIA. The Directors concluded that the fees paid by the Fund in relation to the fees paid by other SIA clients were appropriate and reasonable. The Directors noted that the Fund had not commenced operations, and based on expected levels of assets there was no indication that the Fund’s expenses would be excessive.

The Directors discussed the anticipated benefit SIA will receive from the relationship with the Fund. The Board concluded that any benefits SIA receives from its relationship with the Fund are well within industry norms and are reflected in the amount of the fees paid by the Fund to SIA and are appropriate and reasonable.

Non-Advisory Services. The Directors considered the quality of non-advisory services which SIA provides to its active and operating Funds in the Sit Mutual Fund Family of Funds (and its shareholders) and the quality and depth of SIA’s non-investment personnel who provide such services. Directors concluded that the level of such services and the quality and depth of such personnel are consistent with industry standards.

Finally, the Directors considered the compliance staff and the regulatory history of SIA, and concluded that both are consistent with industry standards.

Item 4:   Principal Accountant Fees and Services.

(a) – (d)   Aggregate fees billed to the registrant for the last two fiscal years for professional services rendered by the registrant’s principal accountant were as follows:

	Audit Fees (a)	Audit Related Fees (b)	Tax Fees (c)	Other Fees (d)
Fiscal year ended March 31, 2007	17,500	0	3,975	0

Audit fees include amounts related to the audit of the registrant’s annual financial statements and services normally provided by the accountant in connection with statutory and regulatory filings. Audit-related fees include amounts reasonably related to the performance of the audit of the registrant’s financial statements, and/or are traditionally performed by the auditor. Tax fees include amounts related to tax compliance, tax planning, and tax advice. Other Fees include services provided to review the Fund’s order processing and trading procedures.

(e)   (1)   The Audit Committee is required to pre-approve audit and non-audit services performed for the registrant by the independent auditor in order to assure that the provision of such services does not impair the auditor’s independence. The audit committee also is required to pre-approve certain non-audit services performed by the registrant’s independent auditor for the registrant’s investment adviser and certain of the adviser’s affiliates if the services relate directly to the operations and financial reporting of the registrant. Services to be provided by the auditor must receive general pre-approval or specific pre-approval by the audit committee.

(h)   The registrant’s audit committee has determined that the provision of non-audit services rendered to the registrant’s investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant, that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is considered compatible with maintaining the principal accountant’s independence.

(h)   The registrant’s audit committee has determined that the provision of non-audit services rendered to the registrant’s investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant, that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is considered compatible with maintaining the principal accountant’s independence.
