CHAIRMAN’S LETTER

May 7, 2012

Dear fellow shareholders:

    U.S. fixed income markets generally performed well over the preceding 12-month period. The year was marked with a variety of significant events. We began the year with a sense of hope as expectations for an economic recovery were high and bond yields had been rising. However, these expectations did not materialize and bond yields declined throughout the year as events unfolded. The economic disruptions began with the earthquake and tsunami in Japan. The impact on economic activity was felt throughout the world. European fiscal concerns continued to dominate the markets as a series of central bank plans were announced and quickly discounted. The deterioration in Greece and lack of a meaningful response sent Treasury yields lower throughout the year. Domestic fiscal issues ensued with political brinkmanship regarding the debt ceiling debate and the ultimate downgrade of the U.S. credit rating by Standard and Poor’s. The Federal Reserve announced a new accommodative policy program and pledged to keep interest rates at historically low levels until late 2014. Recent economic data has been relatively strong, which has tempered some of the pessimism of the second half of 2011. However, we continue to expect subpar economic growth, modest employment gains and moderate inflation in 2012.

    U.S. Treasury bond yields with maturities over 5 years declined by over 100 basis points. Specifically, the 30 year U.S. Treasury bond yield declined 118 basis points, from 4.50% to 3.32% over the 12-month period. Improvement in economic indicators in the first quarter of 2012 has lifted treasury yields off of the lows witnessed in the latter half of 2011, with the 30-year Treasury yield rising by 35 basis points. The municipal funds posted strong double-digit returns for the year, primarily driven by their longer duration.

Europe

    European Union countries came up with increasingly innovative ideas during the year for how to address the fiscal problems of its weaker members. The Greek tragedy took center stage during the second half of the year. By the fourth quarter of 2011, there was acceptance of a de facto Greek default, and in February 2012 the default was made official through a debt swap agreement. Interestingly, the actual default seemed to assuage markets which had grown weary of repeated failed bailout attempts. The recent Long Term Refinancing Operation (LTRO) is a relatively inexpensive loan scheme for European banks from the European Central Bank (ECB) that has boosted liquidity to avoid a collapse of the banking system. Ultimately, we believe this just kicked the can down the road. All of the major issues contributing to the difficulties in Europe persist: the sovereign debt outstanding among the PIIGS (Portugal, Italy, Ire-land, Greece and Spain); banks’ large, cross-border exposure to the euro area; countries’ large government budget deficits; and elevated yield spreads. With confidence eroding and austerity measures impacting many regions in Europe, our expectation is that a modest recession is likely in Euroland in 2012.

Domestic

    In addition to the aforementioned global fiscal issues, we had our own fiscal problems here in the U.S. In April 2011, Standard and Poor’s put the U.S. Credit rating on negative watch. Many hoped this would be an impetus for a bi-partisan solution to the unsustainable debt trajectory. The budget ceiling debate continued throughout the summer, but the much hoped for fiscal responsibility did not materialize. Politics and brinkmanship ensued with a 12^th hour debt ceiling agreement and a “Super Committee” being charged with finding an additional $1.5 trillion in funds before a November deadline. Standard & Poor’s subsequently downgraded the U.S. credit rating from AAA to AA+, citing the high level of debt-to-GDP and the partisan political climate as the ultimate reasons. The “Super Committee” failed to reach a consensus, the consequences of which were to be a combination of cuts in Medicare and defense spending (designed to be unpalatable to both parties). Fitch, Moody’s and S&P all have a negative outlook on the United States debt rating now. The debt limit was raised to a total of $16.4 trillion, a number thought to be high enough to get us through the November elections. However, there may need to be another minor increase to get us through 2012, as the extension of the payroll tax cut and long term benefits resulting from a prolonged below trend economy likely means another year with deficits firmly over $1 trillion.

    Recent economic data has been supportive of stable, albeit modest, Gross Domestic Product (GDP) growth over the near term. Importantly, data has pointed to improvement in the jobs market and modest gains in consumer spending. Home prices will likely turn a corner and begin to rise slowly later this year. Both the number of homes for sale and the pipeline of seriously delinquent mortgages of homes in foreclosure has been steadily declining for nearly 2 years now. The total volume of inventory is down about 25%, and last spring was the first time in four years that home prices experienced a normal seasonal bounce without the aid of tax credits. A precursor to a better housing market is reduced rental vacancy, and vacancies have declined to a 10-year low. So at the very least, the housing market will cease to be a drag on economic growth in 2012 and should add to growth in 2013.

Federal Reserve

    In July, the Federal Reserve announced yet another new program dubbed “Operation Twist.” The intent is to flatten the yield curve and keep mortgage rates low as a form of economic stimulus. To achieve this goal, the Fed sells short-term U.S. Treasury notes and buys longer bonds in an effort to force down longer term yields. Additionally, the Fed reinvests paydowns from its mortgage security holdings into more mortgage securities. Operation Twist is expected to conclude in June of 2012.

2 SIT MUTUAL FUNDS ANNUAL REPORT

    In January 2012, the Federal Reserve announced it would likely not raise interest rates until late 2014, adding yet another layer of monetary easing. Additionally, we have begun to hear the comments about a possible third round of asset purchases (QE3). In contrast, the March release of the FOMC minutes noted “a couple” of committee members favoring additional asset price inflation initiatives down from “a few” in the January meeting minutes. The Fed Chairman, Ben Bernanke, has reiterated that the Federal Reserve will continue to monitor the fragile economy and act accordingly.

Strategy Summary

    2012 has begun with a landscape eerily similar to 2011. Once again, we are enjoying relative economic strength. Job creation and consumer spending have been positive signs, which may have been influenced by the warm weather. The recent FOMC minutes reveal more Fed Governors are favoring less asset purchase initiatives. We expect markets to remain susceptible to active cross currents of improving domestic growth and deteriorating domestic and European fiscal health. European governments have made some progress in dealing with their budget and economic difficulties; however the problems are a long way from being solved. Notwithstanding these concerns, we believe the U.S. economy will continue its slow but steady improvement.

    We continue to position the U.S. Government Fund defensively against rising interest rates, as we expect existing accommodative monetary policy to drive inflation modestly higher in the intermediate term. A lack of bi-partisanship in congress has left little chance for an improvement in the federal budget situation. We continue to see risks to the market surrounding the debt ceiling as the current political interests lack the fortitude to institute meaningful reforms necessary to obtain a sustainable fiscal future. In the short term, we expect longer maturity U.S. Treasury yields to be fairly range bound as the Federal Reserve acquires securities as part of its “Operation Twist” program. We believe opportunities to execute trades on a tactical basis will exist in the Treasury sector until this

program comes to a conclusion later in the second quarter. Importantly, we continue to emphasize older vintage, high-coupon agency mortgage pass thru securities that provide high levels of income at stable price levels.

    The tax-exempt yield-curve remains historically steep. Accordingly, we continue to position municipal bond fund portfolios modestly longer than their associated benchmarks. Furthermore, tax-exempts remain cheap when their yields are expressed as a percentage of comparable maturity Treasuries, particularly for longer maturities. We believe these yield ratios relative to Treasuries continue to offer tax-exempt bonds a cushion if and when Treasury rates begin a sustained increase. Credit spreads remain attractive, particularly for A-rated tax-exempts, which continue to yield over 100 basis points more than AAA-rated general obligation bonds. We continue to look for opportunities to increase credit quality and may begin shortening duration. We believe municipal bond issuance may increase later in 2012, which could present opportunities depending on the composition and timing of issuance. Our investment strategy remains focused on income, which we believe is the primary source of return over longer periods of time. As always, diversification remains a key tenet in our strategy to help manage credit risk, particularly as state and local issuers continue to adjust to fiscal challenges.

    We appreciate your continued interest in the Sit family of funds.

With best wishes,

Roger J. Sit

    Sit U.S. Government Securities Fund

OBJECTIVE & 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 issued, guaranteed or insured by the U.S. government or its agencies or its instrumentalities.

Agency mortgage securities and U.S. Treasury securities are the principal holdings in the Fund. The mortgage securities that the Fund purchases 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).

The Sit U.S. Government Securities Fund provided a return of +2.98% during the twelve month period ended March 31, 2012, compared to the return of the Barclays Intermediate Government Bond Index of +5.66%. The Fund’s 30-day SEC yield was 2.49% and its 12-month distribution rate was 2.77%.

During the twelve month period, the Fund benefited from the income advantage produced by its holdings in older, high coupon government agency mortgage pass-through securities and collateralized mortgage obligations. While the Fund’s holdings of U.S. Government bonds provided meaningful return on an absolute basis, an underweight position in the U.S. Treasury sector, relative to the benchmark, negatively impacted the Fund’s performance. Prices of U.S. Treasury bonds rose as global economic uncertainty produced higher demand for U.S. government obligations, which are typically considered the safest investment option. The Federal Reserve continued to provide economic stimulus through accommodative policy initiatives. In the third quarter of 2011 the Federal Reserve announced it would sell short-term U.S. Treasury notes and buy long-term Treasury bonds (commonly referred to as “Operation Twist”). Prices of longer dated Treasury bonds rose in response.

The government continues to engineer a myriad of mortgage modification and refinancing programs for homeowners who owe more than their homes are worth. Due to their seasoned nature and positive equity, we expect refinancing on the mortgages the Fund holds to remain relatively stable and any impact on the Fund to be modest. Concerns regarding the expansion of refinancing programs caused the prices of the Fund’s mortgages to generally underperform relative to comparable maturity U.S. Treasuries.

Market expectations for additional accommodative policy initiatives from the Federal Reserve have diminished commensurate with improving signs of domestic growth in recent months. While we are concerned that recent warm weather conditions may have pulled forward some economic activity, we expect sustained, albeit slow, growth going forward. Continued uncertainty surrounding the government budget problems both in Europe and domestically combined with typical election year related uncertainty is likely to encourage the Fed to maintain low interest rates. We expect longer-maturity U.S. Treasury yields to rise modestly as Operation Twist comes to a close at the end of June. As such, we are maintaining our underweight position to the U.S.

HYPOTHETICAL GROWTH OF $10,000

The chart above illustrates the total value of a hypothetical $10,000 investment in the Fund over the past 10 years (or for the life of the Fund if shorter) as compared to the performance of the Barclays Intermediate Government Bond Index. Past performance does not guarantee future results. Returns include the reinvestment of distributions. The chart does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares.

¹ The Barclays Intermediate Government Bond Index is a sub-index of the Barclays Government Bond Index covering issues with remaining maturities of between three and five years. The Barclays Government Bond Index is an index that measures the performance of all public U.S. government obligations with remaining maturities of one year or more. The returns include the reinvestment of income and do not include any transaction costs, management fees or other costs. It is not possible to invest directly in an index.

Treasury sector. We continue to focus on older, high-coupon, government-agency, mortgage pass-through securities, as they provide high levels of income with relatively stable prices. This high level of income and stability of principal has been and continues to be the Fund’s focus, as has consistently been the case since the Fund’s inception.

FUND DIVERSIFICATION

Based on total net assets as of March 31, 2012. Subject to change.

PORTFOLIO SUMMARY

Net Asset Value 3/31/12:	$11.31 Per Share
Net Asset Value 3/31/11:	$11.29 Per Share
Total Net Assets:	$1,504.2 Million
30-day SEC Yield 3:	2.49%
12-month Distribution Rate 3:	2.77%
Effective Duration 4:	1.9 Years

³ The SEC Yield reflects the rate at which the Fund is earning income on its current portfolio of securities, while the distribution rate reflects the Fund’s past dividends paid to shareholders based on the net investment income distributed and the average NAV during the past 12 months. Accordingly, the Fund’s SEC yield and distribution rate may differ.

⁴ Duration is a measure of estimated price sensitivity relative to changes in interest rates. Portfolios with longer durations are typically more sensitive to changes in interest rates. For example, if interest rates rise by 1%, the market value of a security with an effective duration of 5 years would decrease by 5%, with all other factors being constant. The correlation between duration and price sensitivity is greater for securities rated investment-grade than it is for securities rated below investment-grade. Duration estimates are based on assumptions by the Adviser and are subject to a number of limitations. Effective duration is calculated based on historical price changes of securities held by the Fund, and therefore is a more accurate estimate of price sensitivity provided interest rates remain within their historical range.

    Sit Tax-Free Income Fund

OBJECTIVE & 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 federal regular 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.

The Sit Tax-Free Income Fund provided a total return of +13.41% for the fiscal year ended March 31, 2012, compared with a total return of +6.90% for the Barclays 5-Year Municipal Bond Index. As of March 31, 2012, the Fund’s 30-day SEC yield was 4.70% and its 12-month distribution rate was 4.60%.

Tax-exempt municipal bond yields declined markedly during the fiscal year, resulting in historically strong returns for the asset class. The yield curve flattened as long-term bond yields declined substantially while intermediate and short yields decreased to a lesser extent. Credit spreads between lower investment grade credits and high-grade municipal bonds also decreased during the period.

The Fund’s outperformance during this period was due to several factors including duration, quality, and industry positioning. The Fund benefited from its longer duration versus the benchmark. From a quality perspective, the Fund benefited by having considerable exposure to bonds rated A or below and non-rated bonds. Noteworthy, however, is that the Fund’s average credit quality improved to A-from BBB+ during the year. Nearly all of the industry segments of the portfolio outperformed the benchmark return. The largest industry segments in the portfolio were other revenue, education/student loan revenue, single-family mortgage revenue, multi-family mortgage revenue, and health care. In total, these five industries comprised roughly two-thirds of the portfolio and each outperformed the benchmark return. In addition, the Fund’s investment in closed-end mutual funds produced an impressive total return during the fiscal year.

The Fund maintains its duration longer than its benchmark, with significant weightings in intermediate and longer-term bonds. The Fund will likely shorten its duration over the course of the next year. Although the tax-exempt yield curve did flatten during the period, it remains steep on a historical basis. We believe that credit spreads for bonds rated A and below remain attractive. Therefore, despite the strong returns provided by the Fund over the past year and the low level of absolute yields at present, we believe the Fund’s duration, credit quality, and industry weightings have it well-positioned for the current environment. As always, our strategy continues to emphasize

HYPOTHETICAL GROWTH OF $10,000

The chart above illustrates the total value of a hypothetical $10,000 investment in the Fund over the past 10 years (or for the life of the Fund if shorter) as compared to the performance of the Barclays 5-Year Municipal Bond Index. Past performance does not guarantee future results. Returns include the reinvestment of distributions. The chart does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares.

¹ The Barclays 5-Year Municipal Bond Index is the 5 year (4-6) component of the Municipal Bond Index, an unmanaged, rules-based, market-value-weighted index for the long-term tax-exempt bond market. The index includes bonds with a minimum credit rating of BBB. The returns include the reinvestment of income and do not include any transaction costs, management fees or other costs. It is not possible to invest directly in an index.

income, which we believe is the primary driver of return over the long run. Diversification remains a key factor in managing risk.

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. Current performance may be lower or higher than the performance data quoted. Contact the Fund for performance data current to the most recent month-end. Returns include changes in share price as well as reinvestment of all dividends and capital gains and all fee waivers. Without the fee waivers total return and yield figures would have been lower. Returns do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. Management fees and administrative expenses are included in the Fund’s performance. Returns for periods greater than one year are compounded average annual rates of return.

³ The SEC Yield reflects the rate at which the Fund is earning income on its current portfolio of securities, while the distribution rate reflects the Fund’s past dividends paid to shareholders based on the net investment income distributed and the average NAV during the past 12 months. Accordingly, the Fund’s SEC yield and distribution rate may differ.

⁴ The tax-equivalent yield is based on an assumed tax rate of 35.0%.

⁵ Duration is a measure of estimated price sensitivity relative to changes in interest rates. Portfolios with longer durations are typically more sensitive to changes in interest rates. For example, if interest rates rise by 1%, the market value of a security with an effective duration of 5 years would decrease by 5%, with all other factors being constant. The correlation between duration and price sensitivity is greater for securities rated investment-grade than it is for securities rated below investment-grade. Duration estimates are based on assumptions by the Adviser and are subject to a number of limitations. Effective duration is calculated based on historical price changes of securities held by the Fund, and therefore is a more accurate estimate of price sensitivity provided interest rates remain within their historical range.

    Sit Minnesota Tax-Free Income Fund

OBJECTIVE & 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 federal regular income tax and Minnesota regular personal income tax. The Fund anticipates that substantially all of its distributions to its shareholders will be exempt as such. For investors subject to the alternative minimum tax (“AMT”), up to 20% of the Fund’s income may be alternative minimum taxable income.

The Sit Minnesota Tax-Free Income Fund provided a total return of +12.48% for the fiscal year ended March 31, 2012, compared with a total return of +6.90% for the Barclays 5-Year Municipal Bond Index. As of March 31, 2012, the Fund’s 30-day SEC yield was 3.96% and its 12-month distribution rate was 4.30%.

Tax-exempt municipal bond yields declined markedly during the fiscal year, resulting in historically strong returns for the asset class. The yield curve flattened as long-term bond yields declined substantially while intermediate and short yields decreased to a lesser extent. The fiscal situation in Minnesota improved during the year and employment in Minnesota continues to be stronger than the nation. The credit spread between high-grade Minnesota bonds and comparable national issues increased slightly during the year. Credit spreads between lower investment grade credits and high-grade municipal bonds decreased during the period.

The Fund’s outperformance during this period was due to several factors including duration, quality, and industry positioning. The Fund benefited from its longer duration versus the Index. From a quality perspective, the Fund maintained its average credit quality at A, and it benefited from its considerable exposure to A-rated bonds and below in addition to non-rated securities. All of the industry segments in the portfolio outperformed the benchmark return and produced double-digit total returns. The largest industry weightings as of March 31, 2012 were hospital/healthcare revenue, multi-family mortgage revenue, and single-family mortgage revenue.

The Fund maintains its duration longer than its benchmark, with significant weightings in intermediate and longer-term bonds. The Fund will likely shorten its duration over the course of the next year. Although the tax-exempt yield curve did flatten during the period, it remains steep on a historical basis. We believe that credit spreads for bonds rated A and below remain attractive. Therefore, despite the strong returns provided by the

HYPOTHETICAL GROWTH OF $10,000

The chart above illustrates the total value of a hypothetical $10,000 investment in the Fund over the past 10 years (or for the life of the Fund if shorter) as compared to the performance of the Barclays 5-Year Municipal Bond Index. Past performance does not guarantee future results. Returns include the reinvestment of distributions. The chart does not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares.

¹ The Barclays 5-Year Municipal Bond Index is the 5 year (4-6) component of the Municipal Bond Index, an unmanaged, rules-based, market-value-weighted index for the long-term tax-exempt bond market. The index includes bonds with a minimum credit rating of BBB. The returns include the reinvestment of income and do not include any transaction costs, management fees or other costs. It is not possible to invest directly in an index.

Fund over the past year and the low level of absolute yields at present, we believe the Fund’s duration, credit quality, and industry weightings position it well for the current environment. As always, our strategy continues to emphasize income, which we believe is the primary driver of return over the long run.

³ The SEC Yield reflects the rate at which the Fund is earning income on its current portfolio of securities, while the distribution rate reflects the Fund’s past dividends paid to shareholders based on the net investment income distributed and the average NAV during the past 12 months. Accordingly, the Fund’s SEC yield and distribution rate may differ.

⁴ The tax-equivalent yield is based on an assumed federal tax rate of 35.0% and a Minnesota tax rate of 7.85%, for an effective combined tax rate of 40.1%.

⁵ Duration is a measure of estimated price sensitivity relative to changes in interest rates. Portfolios with longer durations are typically more sensitive to changes in interest rates. For example, if interest rates rise by 1%, the market value of a security with an effective duration of 5 years would decrease by 5%, with all other factors being constant. The correlation between duration and price sensitivity is greater for securities rated investment-grade than it is for securities rated below investment-grade. Duration estimates are based on assumptions by the Adviser and are subject to a number of limitations. Effective duration is calculated based on historical price changes of securities held by the Fund, and therefore is a more accurate estimate of price sensitivity provided interest rates remain within their historical range.

40 SIT MUTUAL FUNDS ANNUAL REPORT

[This page intentionally left blank.]

MARCH 31, 2012 41

NOTES TO FINANCIAL STATEMENTS

Year Ended March 31, 2012

(1) Organization

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 Tax-Free Income Fund which is 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. 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 of these Funds is as follows:

Fund	Investment Objective
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.

(2) Significant Accounting Policies

Investments in Securities

Investment securities are carried at fair value based upon closing market quotations on the last business day of the period. Investments in securities traded on national or international securities exchanges are valued at the last reported sales price prior to the time when assets are valued. Securities traded on the over-the-counter market are valued at the last reported sales price or if the last sales price is not available, at the last reported bid price. Consistent with the Funds’ valuation policies and procedures, the current fair value of certain fixed income securities is provided by an independent pricing service. Fixed income securities for which prices are not available from an independent pricing service but where an active market exists are valued using market quotations obtained from broker-dealers or quotation systems. Securities for which market quotations are not available, such as private placement securities, are valued at fair value according to methods selected in good faith by Sit Investment Associates, Inc. (the “Adviser”) and may include dealer-supplied valuations. Short-term investments of sufficient credit quality with maturities of 60 days or less when acquired, or which subsequently are within 60 days of maturity, are valued at amortized cost, which approximates fair value. Option and future contracts entered into and held by the Funds are valued at the close of the securities and commodities exchange on which they are traded.

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 Dividend Income and distributions from capital gains, if any, are included in Net Realized Gain (Loss).

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.

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.

Derivative Instruments

The Funds apply derivative instrument disclosure standards in order to enable investors to understand how and why the Funds use derivatives, how derivatives are accounted for, and how derivative instruments affect the Funds’ financial statements.

42 SIT MUTUAL FUNDS ANNUAL REPORT

NOTES TO FINANCIAL STATEMENTS

Year Ended March 31, 2012 (Continued)

To hedge interest rate risk, the U.S. Government Securities Fund purchased put option and wrote call option contracts traded on a U.S. exchange. Risks of purchasing and writing options include the possibility of an illiquid market and that a change in the value of the option may not correlate with changes in the value of the underlying securities.

The premiums paid for the options represent the cost of the investment and the options are valued daily at their closing price. The Funds recognize a realized gain or loss when the option is sold or expired. Option holdings within the Funds, which may include put options and call options, are subject to loss of value with the passage of time, and may experience a total loss of value upon expiration. With options, there is minimal counterparty risk to the Funds since they are exchange traded. During the year ended March 31, 2012, the average cost for purchased options and premium received in the U.S. Government Securities Fund for written options were $486,355 and $287,668, respectively. The number of open option contracts outstanding as of March 31, 2012 and the amounts of realized gain (loss) and changes in unrealized appreciation (depreciation), as disclosed below, also serve as indicators of the volume of activity for the Fund throughout the year.

Fair Value Measurements

The inputs and valuations techniques used to measure fair value of the Funds’ net assets are summarized into three levels as described in the hierarchy below:

MARCH 31, 2012 43

NOTES TO FINANCIAL STATEMENTS

Year Ended March 31, 2012 (Continued)

• Level 1 – quoted prices for active markets for identical securities. An active market for the security is a market in which transactions occur with sufficient frequency and volume to provide pricing information on an ongoing basis. A quoted price in an active market provides the most reliable evidence of fair value.

• Level 2 – debt securities are valued based on evaluated prices received from independent pricing services or from dealers who make markets in such securities. For corporate bonds, U.S. government and government agency obligations, and municipal securities the pricing services utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity, and type as well as dealer supplied prices. For asset-backed securities and mortgage-backed securities, the pricing services utilize matrix pricing which considers prepayment speed assumptions, attributes of the collateral, yield or price of bonds of comparable quality, coupon, maturity, and type as well as dealer supplied prices. All of these inputs are derived principally from or corroborated by observable market data. An adjustment to any observable input that is significant to the fair value may render the measurement a Level 3 measurement.

• Level 3 – significant unobservable inputs, including the Adviser’s own assumptions in determining the fair value of investments.

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The fair value of the Funds’ bonds are generally based on quotes received from brokers or independent pricing services. Bonds with quotes that are based on actual trades with a sufficient level of activity on or near the measurement date are classified as Level 2 assets.

At the end of each calendar quarter, management evaluates the Level 2 and 3 assets and liabilities for changes in liquidity, including but not limited to: whether a broker is willing to execute at the quoted price, the depth and consistency of prices from third party services, and the existence of contemporaneous, observable trades in the market. Additionally, management evaluates the Level 1 and 2 assets and liabilities on a quarterly basis for changes in listings or delistings on national exchanges. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of the Funds’ investments may fluctuate from period to period. Additionally, the fair value of investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values the Fund may ultimately realize. Further, such investments may be subject to legal and other restrictions on resale or otherwise are less liquid than publicly traded securities.

A summary of the levels for the Funds’ investments as of March 31, 2012 is included with the Funds’ schedules of investments.

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. The Funds have recorded in their financial statements the full benefit of their tax positions taken in connection with the RIC qualification and distribution requirements of the RIC. 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.

Management has analyzed the Funds’ tax positions taken in federal tax returns for all open tax years and has concluded that as of March 31, 2012, no provision for income tax would be required in the Funds’ financial statements. The Funds’ federal and state income and federal excise returns for the 2009, 2010, and 2011 tax years for which the applicable statutes of limitations have not expired remain subject to examination by the Internal Revenue Service and state departments of revenue.

NOTES TO FINANCIAL STATEMENTS

Year Ended March 31, 2012 (Continued)

Net capital loss carryovers and late year losses, if any, as of March 31, 2012, are available to offset future realized capital gains and thereby reduce future capital gains distributions. Under the Regulated Investment Company Modernization Act of 2010 (“Act”), the Funds’ are permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period. Any losses incurred during those future taxable years will be required to be utilized prior to any losses incurred in pre-enactment taxable years. Additionally, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses, and will not be considered exclusively short-term as under previous law. The Funds’ first fiscal year end subject to the Modernization Act is March 31, 2012. The net capital loss carryovers and the expiration dates for capital losses carryover from pre-enactment taxable years and the late year losses deferred as of March 31, 2012, were as follows:

	Pre-Enactment Net Capital Loss Carryover Expiring in:				Post-Enactment Unlimited Period of Net Capital Loss Carryover				Late Year Losses		Accumulated Capital and

Minnesota Tax-Free Income	—		2012		403,028

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 for the respective periods. Actual results could differ from those estimates.

Guarantees and Indemnifications

Under each Fund’s organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to each Fund. In addition, certain of each Fund’s contracts with its service providers contain general indemnification clauses. Each Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against each Fund cannot be determined and each Fund has no historical basis for predicting the likelihood of any such claims.

(3) Investment Security Transactions

The cost of purchases of and proceeds from sales and maturities of investment securities, other than short-term securities, for the year ended March 31, 2012, were as follows:

	Purchases				Proceeds

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders:

        Sit U.S. Government Securities Fund, Inc.

        Sit Mutual Funds II, Inc.

We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of Sit U.S. Government Securities Fund, Inc., Sit Tax-Free Income Fund (a series of Sit Mutual Funds II, Inc.), and Sit Minnesota Tax-Free Income Fund (a series of Sit Mutual Funds II, Inc.) (the “Funds”), as of March 31, 2012, 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 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, 2012, by correspondence with the custodian and brokers or by performing 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 U.S. Government Securities Fund, Sit Tax-Free Income Fund, and Sit Minnesota Tax-Free Income Fund as of March 31, 2012, 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 in the five-year period then ended, in conformity with U.S. generally accepted accounting principles.

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, 2011 to March 31, 2012.

Actual Expenses

The first line of the following table 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 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 Account Value (10/1/11)	Ending Account Value (3/31/12)		Expenses Paid During Period* (10/1/11- 3/31/12)
U.S. Government Securities Fund
Actual	$1,000	$	1,010.20	$4.03
Hypothetical	$1,000	$	1,021.06	$4.05
Tax-Free Income Fund
Actual	$1,000	$	1,050.00	$4.11
Hypothetical	$1,000	$	1,021.06	$4.05
Minnesota Tax-Free Income Fund
Actual	$1,000	$	1,041.90	$4.09
Hypothetical	$1,000	$	1,021.06	$4.05

*Expenses are equal to the Funds’ annualized expense ratio of 0.80% multiplied by the average account value over the period, multiplied by 183/365 (to reflect the one-half year period.)

RE-APPROVAL OF INVESTMENT MANAGEMENT AGREEMENTS

At their joint meeting held on October 24, 2011 the Boards of Directors of the Sit Mutual Funds unanimously approved the continuation for another one year period the investment management agreements entered into by and between Sit Investment Associates, Inc. (“SIA”) and Sit Mutual Funds II, Inc. dated November 1, 1992; and Sit U.S. Government Securities Fund, Inc. dated November 1, 1992 (the “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 and the nature, extent and quality of the services performed by SIA, 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 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 professionals are actively involved in the investment process and have significant investment industry experience.

54 SIT MUTUAL FUNDS ANNUAL REPORT

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 $10.8 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.

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.

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. 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 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.

ADDITIONAL INFORMATION (Unaudited) (Continued)

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.

Based on these conclusions, without any single conclusion being dispositive, the Directors determined that renewal of the Agreements was in the interest of each Fund and its shareholders.

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.

Tax fees include amounts related to tax compliance, tax planning, and tax advice.

(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. Any proposed services exceeding pre-approved cost levels will require separate pre-approval by the audit committee.

The audit committee may delegate pre-approval authority to the audit committee chairman. The chairman shall report any pre-approval decisions to the audit committee at its next scheduled meeting. The audit committee does not delegate its responsibility to pre-approve services performed by the independent auditor to management.

(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.
