CHAIRMAN’S LETTER

May 6, 2015

Dear fellow shareholders:

With U.S. GDP growing at a moderate pace, European economies continuing to recover, and global inflation rates at subdued levels, the domestic and global bond markets have become increasingly captivated by reacting to and anticipating the actions of the U.S. Federal Reserve (the Fed). Now that the issue of the “taper” the reduction in the monthly purchases of U.S. Treasury and mortgage-backed securities - is done (the Fed has now fully “tapered”), the next milestone to watch is when the Fed will vote to end its zero interest rate policy by increasing its target for the Federal Funds rate.

The Fed Funds rate is, in theory, the rate at which banks trade balances held at the Federal Reserve to each other overnight. In practice, the rate carries a lot more significance as a benchmark-type rate which the Fed targets in an attempt to influence the economic activity in the U.S. The influence works because, in general, other interest rates in the economy, such as the rate at which banks give mortgage or small business loans, are related to the Fed Funds rate and the economy can be stimulated by lowering interest rates or cooled down by raising them.

Thus, by changing the Fed Funds rate, the Federal Reserve wields a powerful tool to change the course of economic activity. The process by which the governors of the Fed make the decision to attempt to stimulate or to cool down the economy is by looking to their “dual mandate” of maximum employment and stable prices. The dual mandate may seem straightforward to interpret in theory; however, in practice it is not. Consequently, the issue of when and by how much the Fed “raises rates” is an issue of intense discussion. The rest of the letter lays out our thinking on the topic. However, if you want the “short” version, we believe that the Fed may raise rates this year, but if they do raise rates it will likely not be by very much.

Employment

The issue of employment is one that is seemingly simple and yet frustratingly complex. It is simple in that we have many quantitative measures of employment that are reported on a regular basis. It is complex in that the concept of “maximum employment” is not well-defined and that the many different measures of employment may not always agree with one another.

For example, the most accessible and widely followed statistic is “the unemployment rate,” which is simply the number of people actively looking for work divided by the total number of people in the “labor force” (people employed or actively looking for work). As of March, this number was 5.5%. The unemployment rate was below 5.0% during much of the last economic expansion and peaked at 10.1% during the financial crisis.

Another widely followed statistic is the so-called “underemployment” rate which also includes “people marginally attached to the labor force” (people not currently looking but that want a job) and people employed “part-time for economic reasons” (people that would

take full-time work if they could find it). As of March, the underemployment rate was 10.9%. This reading, like the unemployment rate, is down from the 17.1% peak during the crisis. However, this level is still higher than it ever was in the prior recession: underemployment only rose to 10.4% in 2003 following the bursting of the tech bubble.

Another statistic that is frequently used to gauge the health of U.S. employment is the employment to population ratio, which is simply the number of employed people divided by the working-age population. Unlike the rebound seen in the unemployment and underemployment statistics, this ratio continues to lag. The March reading was 59.3%. This is an improvement from the low of the 58.2% during the financial crisis but still the lowest level outside of the current recession since the mid-1980s.

However, looking at the “working-age” population might be too broad since baby-boomers are moving out of the workforce and millennials are staying in school longer before entering the work force than in times past. Adjusting the ratio to look just at 25-54 year olds gives a distinctly different picture: the March reading was 77.2%. Again, this is lower than the previous period of growth, but has recovered from the recession low of 74.8% much more strongly than the broader working-age figure.

Balancing the pessimistic readings of stubbornly high underemployment and low employment to population ratio against the optimistic readings of lower unemployment and relatively better performance in employment to population ratio among people aged 25-54, we believe the truth lies somewhere in the middle. The 5.5% unemployment rate probably isn’t strictly comparable to other times in history when the rate was the same due to the high number of part-time workers. Similarly, the employment to population ratio probably isn’t comparable either given the numbers of baby boomers retiring. The Fed believes that when the economy reaches “maximum employment” it is typically accompanied by increased inflationary pressure, which ties together the first and second parts of their mandate.

Inflation

Like employment, gauging inflation can be simple and complex. There are many quantitative measurements of inflation as well as opinions of what is the “right” amount of inflation. The Fed’s goal is “stable prices” which they define as about 2.0% inflation.

The most commonly cited measure of inflation, the consumer price index (CPI), comes in two flavors: “all items” and “core.” Core inflation removes some of the most volatile items (food and energy) which some economists believe are not predictive of sustained inflation. The year-over-year March measurement for annual inflation for all-items CPI (0.1%) and core CPI (1.8%) are both below the 2.0% target. However, the Fed’s preferred measure of inflation is actually

2 SIT MUTUAL FUNDS ANNUAL REPORT

Personal Consumption Expenditures (PCE) which is meant to track consumer or household spending. Similar to the readings of CPI, the year-over-year March measurement for annual inflation of all-items PCE (0.3%) and core PCE (1.4%) are also both below the Fed’s 2.0% target.

There are also alternative measures of inflation calculated by non-government parties. One particularly well-regarded measure is MIT’s Billion Prices Project (BPP) which collects prices from online retailers daily. Their statistic has generally tracked all-items CPI and is also below 2.0%.

While not a measure of “broad” inflation, another useful measure that relates to both aspects of the dual mandate is wage inflation. One widely looked at measure is the growth in average hourly earnings of nonsupervisory employees. The year-over-year March measurement was 1.8%, meaning that wages have recently begun to rise and are growing faster than “core” PCE inflation.

The story told by the inflation figures is probably less confusing than that of employment since by most measures inflation is currently running below the Fed’s 2.0% target. Thus, we believe that the Fed currently isn’t feeling pressure to raise interest rates to contain an overheating economy. However, if core PCE inflation numbers move upward or if wage inflation climbs higher, that could trigger more aggressive action by the Fed.

Strategy

Our view regarding Fed policy is that as long as the economy grows at a moderate pace, it is strong enough that we no longer need the extreme of a zero interest rate policy. However, we also believe that if core PCE inflation remains below target, that interest rates will not rise drastically. We have adjusted our Funds accordingly and believe that they are well-positioned for the eventual increase in rates by the Fed while continuing to earn substantial levels of current income.

The U.S. Government Securities Fund remains focused on seasoned, high coupon agency-backed securities which should continue to provide long-term income stability and principal preservation as mortgage rates increase from all-time lows. Stability in the Sit Quality Income Fund remains impressive and we are pleased that despite our focus on shorter than benchmark duration we were able to beat our benchmark over the past year. We believe that the Fund’s stable price makes it a good choice for cash reserves.

The tax-exempt fixed income strategy employed in managing both the Tax-Free Income Fund and the Minnesota Tax-Free Income Fund will continue to focus heavily on the use of high coupon bonds and bonds structured with put, call, sinking fund, and prepayment provisions that provide regular cash flow. We believe that our investment strategy’s focus on income, which we believe is the primary source of return over longer periods of time, will continue to deliver positive performance. We continue to focus on sectors and security structures that provide incremental yield, while using diversification to help manage credit risk.

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 Association (FNMA), and Federal Home Loan Mortgage Corporation (FHLMC).

The Sit U.S. Government Securities Fund provided a return of +2.37% during the year ended March 31, 2015, compared to the return of the Barclays Intermediate Government Bond Index of +3.15%. The Fund’s 30-day SEC yield was 2.92% and its 12-month distribution rate was 1.89%.

During the 12-month period, the Fund benefitted from its position in high coupon government agency mortgages, due to a slowdown in mortgage prepayments. The Fund’s strong income return offset modest price declines resulting in positive performance on an absolute basis. Treasury futures and options that are used for duration management hindered performance, which is typical during periods of declining interest rates. In October, the Federal Reserve announced the completion of its asset purchase program, which has increased speculation on when it will increase short-term interest rates. As a result, interest rates rose modestly on the short end of the curve. The Federal Open Market Committee also revised its estimate for 2015, 2016, and 2017 growth lower to around 2.50% annually, which has, in all likelihood, postponed the eventual rise in the Fed Funds rate from this summer to later this year. Meanwhile, interest rates on longer term maturities declined due to decreased inflation expectations resulting from lower oil prices.

As the bond market prepares for the eventual increase in the Fed Funds rate, we expect short-term yields to increase while long-term yields exhibit little change. Continued low inflation expectations should offset the Fed’s anticipated rate increases, resulting in smaller yield movement for long maturity securities than for short-term securities. We also believe that mortgage prepayments on the high-coupon government agency mortgages held in the Fund will remain stable.

We continue to position the Fund defensively against a rising short-term rate environment. Our core investments continue to be older, high coupon government agency mortgage pass-through securities, as they provide high levels of income with relatively stable prices.

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. This is the Fund’s primary index.

This high level of income and principal stability 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, 2015. Subject to change.

PORTFOLIO SUMMARY
Net Asset Value 3/31/15:	$ 11.09 Per Share
Net Asset Value 3/31/14:	$ 11.04 Per Share
Total Net Assets:	$ 587.2 Million
Effective Duration 3:	0.2 Years

3 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 fair 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 Quality Income Fund

OBJECTIVE & STRATEGY

The objective of the Quality Income Fund is to provide high current income and safety of principal, which it seeks to attain by investing at least 80% of its assets in debt securities issued by the U.S. government and its agencies, debt securities issued by corporations, mortgage and other asset-backed securities. The Fund invests at least 50% of its assets in U.S. government debt securities, which are securities issued, guaranteed or insured by the U.S. government, its agencies or instrumentalities.

The Sit Quality Income Fund provided a return of +0.36% during the year ended March 31, 2015, compared to the return of the Barclays 1-3 year Government/Credit Bond Index of +1.12%. The Fund’s 30-day SEC yield was 1.04% and its 12-month distribution rate was 0.66%.

The primary goal of the Fund is to maintain a high credit quality portfolio with stable principal values, while generating a relatively high level of income. During the year, the Fund benefitted from the income advantage produced by its holdings in non-agency residential mortgage, corporate, and taxable municipal securities. Non-agency residential mortgages outperformed as higher home prices increased demand for these securities. Corporate bonds benefitted from improving profits which resulted in increased demand as well. Taxable municipal securities also saw higher demand as higher tax revenues resulted in better balance sheets for many municipalities. The lower yields of Treasury securities hindered performance, as did the Treasury futures and options used for duration management. This is typical during periods of declining interest rates, such as the environment experienced over the 12-month period.

In October, the Federal Reserve announced the completion of its asset purchase program, which has increased speculation on when it will increase the fed funds rate target. As a result, interest rates rose modestly on the short end of the curve. The Federal Open Market Committee also revised its estimate for 2015, 2016, and 2017 growth lower to around 2.50% annually, which has, in all likelihood, postponed the eventual raise in the Fed Funds rate from this summer to later this year. Meanwhile, interest rates on longer term maturities declined due to decreased inflation expectations resulting from lower oil prices.

We expect the economy to continue to improve and the jobs market to strengthen further. We have started to see positive effects of lower gasoline and oil prices. Consumers were hesitant, at first, to spend their excess cash on non-essential goods. As gasoline prices have remained lower, we have seen increased spending which has begun to flow into the economy. In addition, we expect interest rates on longer term maturities to continue to decline with lower energy prices and lower inflation expectations. However, as the economy gains steam, we expect the entire yield curve to shift higher led by short term interest rates.

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 1-3 Year Government/Credit 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 1-3 Year Government/Credit Index is an unmanaged index of Treasury or government agency securities and investment grade corporate debt securities with maturities of one to three years. 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.

We have positioned the Fund defensively against a rising rate environment, using a diverse universe of high-quality assets and Treasury futures and options for duration management. We are focusing on a combination of Treasury, agency, and credit sectors that provide relatively high levels of income and relatively stable prices. The dual goals of income and principal stability are the primary objectives the Fund.

Net Asset Value 3/31/15:	$9.94 Per Share
Net Asset Value 3/31/14:	$9.97 Per Share
Total Net Assets:	$124.4 Million
Average Maturity:	8.6 Years
Effective Duration 3:	0.1 Years

³ 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 fair 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 +9.81% during the fiscal year ended March 31, 2015, compared with a total return of +2.95% for the Barclays 5-Year Municipal Bond Index. As of March 31, 2015, the Fund’s 30-day SEC yield was 3.06% and the Fund’s 12-month distribution rate was 3.86%.

Yields on long and intermediate tax-exempt municipal bonds ended the year lower while yields on the shortest bonds rose slightly, resulting in a flattening on the yield curve. Tax-exempt yields began the fiscal year by falling in April and May and then stabilizing into the summer. Yields declined again in August and held stable through the fall with a modest decline through the end of December. Finally, yields declined further in January, saw a moderate rebound higher in February, and ultimately ended lower for both the quarter and the fiscal year.

The Fund maintained duration longer than its benchmark, a key driver of the Fund’s outperformance in fiscal year 2015. Bonds with duration longer than five years significantly outperformed shorter duration bonds during the year. Lower credit quality also outperformed higher credit quality during the fiscal year. The Fund’s non-rated holdings, which accounted for 22% of the Fund at fiscal year-end, generated materially higher returns, on average, than the Fund’s rated holdings. Security selection was a significant contributor to the Fund’s outperformance and was strong across the board, generating returns several percentage points higher than those of the Barclays 5-Year Municipal Bond Index in all five of the largest sectors held. An emphasis on revenue bonds led to overweight positions in the Single Family Housing, Multi Family Housing, and Other Revenue sectors, all of which provided a boost to the Fund’s performance.

Credit spreads narrowed considerably during the fiscal year. The Fund will continue to look for opportunities to increase its allocation to higher-rated bonds in light of the decreased compensation for credit risk. The Fund’s duration currently remains longer than that of the benchmark. We will look to shorten the current duration as we anticipate interest rates will begin to rise later in 2015.

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. This is the Fund’s primary index.

We believe the Fund is well positioned to provide attractive relative yield in the current market environment. Our strategy remains focused on providing a high level of interest income, which we believe is the primary driver of long run returns. The Fund remains highly diversified in order to manage credit 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 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 fair 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 +6.62% during the fiscal year ended March 31, 2015, compared with a total return of +2.95% for the Barclays 5-Year Municipal Bond Index. As of March 31, 2015, the Fund’s 30-day SEC yield was +2.57% and the Fund’s 12-month distribution rate was 3.44%.

Yields on long and intermediate tax-exempt municipal bonds ended the year lower while yields on the shortest bonds rose slightly, resulting in a flattening on the yield curve. Tax-exempt yields began the year by falling in April and May and then stabilizing into the summer.Yields declined again in August and held stable through the fall with a modest decline through the end of December. Finally, yields declined further in January, saw a moderate rebound higher in February, and ultimately ended lower for both the quarter and the fiscal year.

Minnesota’s economic situation remains stronger than that of many other parts of the country. The state benefits from a diverse economy and good fiscal discipline, leading to generally higher credit ratings. These factors have historically resulted in Minnesota municipal bonds experiencing less volatility than those of many other states which face more significant financial headwinds.

The Fund maintained duration longer than its benchmark, a key driver of the Fund’s outperformance in fiscal year 2015. Bonds with duration longer than five years significantly outperformed shorter duration bonds during the year. Lower credit quality also outperformed higher credit quality during the fiscal year. The Fund’s non-rated holdings, which accounted for 31.1% of the Fund at fiscal year-end, generated materially higher returns, on average, than the Fund’s rated holdings. Security selection was a significant contributor to the Fund’s outperformance and was strong across the board, generating returns several percentage points higher than those of the Barclays 5-Year Municipal Bond Index in all five of the largest sectors held. An emphasis on revenue bonds led to overweight positions in the Education, Single Family Housing, and Multi Family Housing sectors, all of which provided a boost to the Fund’s performance.

Credit spreads narrowed considerably during the fiscal year. The Fund will continue to look for opportunities to increase its allocation to

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. This is the Fund’s primary index.

higher-rated bonds in light of the decreased compensation for credit risk. The Fund’s duration currently remains longer than that of its benchmark. We expect to maintain duration at or near its current level during fiscal 2016.

We believe the Fund is well positioned to provide attractive relative yield in the current market environment. Our strategy remains focused on providing a high level of interest income, which we believe is the primary driver of long run returns. The Fund remains highly diversified in order to manage credit risk.

Average Maturity:	15.2 Years
Effective Duration 3:	4.6 Years

3 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 fair 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.

NOTES TO FINANCIAL STATEMENTS

Year Ended March 31, 2015

(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 Quality Income Fund, Sit Tax-Free Income Fund and Minnesota 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.
Quality Income Fund	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

The Funds are investment companies and follow accounting and reporting guidance under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, “Financial Services-Investment Companies”. The following is a summary of significant accounting policies consistently followed by the Funds in the preparation of their financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”).

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. The sale and bid prices or prices deemed best to reflect fair value quoted by dealers who make markets in these securities are obtained from independent pricing services. 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 or other inputs and assumptions that pricing services would typically utilize. 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.

52 SIT MUTUAL FUNDS ANNUAL REPORT

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.

To hedge interest rate risk, the U.S. Government Securities Fund purchased put options and wrote call option contracts traded on a U.S. exchange. To hedge interest rate risk, the Quality Income Fund purchased put options, entered into futures contracts and wrote call options on these future contracts traded on a U.S. exchange. Risks of entering into futures contracts and 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.

Upon entering into a futures contract, the Quality Income Fund is required to deposit either cash or securities in an amount (initial margin) equal to a certain percentage of the contract value. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are equal to the daily changes in the contract value and are recorded as unrealized gains and losses. The Fund recognizes a realized gain or loss when the contract is closed or expired. With futures contracts, there is minimal counterparty risk to the Fund since futures are exchange traded and the exchange’s clearinghouse, as counterparty to all exchange-traded futures, guarantees the futures against default.

During the year ended March 31, 2015, the average volume of derivative activity was as follows:

	Average Cost		Average Premium Received		Average Notional Amount
U.S. Government Securities Fund
Purchased put options	$	663,570		—	$	3,215,200
Written call options		—	$	2,685,205		7,720,000
Quality Income Fund
Purchased put options	$	14,887		—	$	47,800
Treasury futures		—		—		64,916,029
Written call options		—	$	24,768		73,000

The number of open option contracts and open futures contracts outstanding as of March 31, 2015 also serve as indicators of the volume of activity for the Funds throughout the period.

Fair Value Measurements

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

• Level 1 – quoted prices in 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, 2015 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 their taxable income to shareholders. The Funds have recorded in their financial statements the full benefit of their tax positions taken in connection with the Registered Investment Company (RIC) qualification and distribution requirements of the

MARCH 31, 2015 55

NOTES TO FINANCIAL STATEMENTS

Year Ended March 31, 2015 (Continued)

Internal Revenue Code. 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, 2015, 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 2012, 2013, and 2014 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.

At March 31, 2015, the gross unrealized appreciation (depreciation) on investments and cost of securities on a tax basis for federal income tax purposes were as follows:

	Unrealized     Appreciation		Unrealized Depreciation			Net Unrealized Appreciation (Depreciation)		Cost of Securities on a Tax Basis
U.S. Government Securities		$23,049,399		($8,524,178	)		$14,525,221		$547,497,250
Quality Income		487,507		(180,960	)		306,547		124,434,442
Tax-Free Income		9,868,416		(19,274,802	)		(9,406,386)		173,132,341
Minnesota Tax-Free Income		17,050,783		(1,983,268	)		15,067,515		384,911,842

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 or period ended March 31, 2015 and 2014 were as follows:

Year Ended March 31, 2015:

	Ordinary Income		Tax-Exempt Income		Long Term Capital Gain	Total
U.S. Government Securities		$11,708,730		—	—		$11,708,730

Minnesota Tax-Free Income*		56,423		13,651,571	—		13,707,994

*99.0% and 99.6% of dividends were derived from interest on tax-exempt securities, on the Tax-Free Income and Minnesota Tax-Free Income Funds, respectively.

Year Ended March 31, 2014:

	Ordinary Income		Tax-Exempt Income		Long Term Capital Gain	Total
U.S. Government Securities		$10,762,504		—	—		$10,762,504

Minnesota Tax-Free Income*		101,933		14,518,661	—		14,620,594

* 97.9% and 99.3% of dividends were derived from interest on tax-exempt securities, on the Tax-Free Income and Minnesota Tax-Free Income Funds, respectively.

As of March 31, 2015 the components of distributable earnings on a tax basis were as follows:

	Undistributed Ordinary Income		Undistributed Tax-Exempt Income		Accumulated Gain (Loss)			Unrealized Appreciation (Depreciation)
U.S. Government Securities		$59,323		—		($15,338,366	)		$14,525,221

Minnesota Tax-Free Income		—		196,217		(7,030,514	)		15,067,515

56 SIT MUTUAL FUNDS ANNUAL REPORT

On the statement of assets and liabilities, as a result of permanent book-to-tax differences, reclassification adjustments were made to the following capital accounts:

	Undistributed Net Investment Income			Accumulated Net Realized Gain (Loss)		Additional Paid-in Capital
Tax-Free Income		($4,777	)		$4,777		—
Minnesota Tax-Free Income		(18,032	)		792,874		($774,842)

These differences were primarily attributable to market discount accretion adjustments and capital loss carryovers expiring.

Net capital loss carryovers and late year losses, if any, as of March 31, 2015, 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 was 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, 2015, were as follows:

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

For the year ended March 31, 2015, the Funds’ utilized capital losses and expired capital losses as follows:

	Utilized	Expired
Minnesota Tax-Free Income	—	$774,842

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.

NOTES TO FINANCIAL STATEMENTS

Year Ended March 31, 2015 (Continued)

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.

The cost of purchases and proceeds from sales and maturities of investment securities, other than short-term securities, for the year ended March 31, 2015, were as follows:

58 SIT MUTUAL FUNDS ANNUAL REPORT

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 of Sit U.S. Government Securities Fund, Inc., and Sit Quality Income Fund, Sit Tax-Free Income Fund, and Sit Minnesota Tax-Free Income Fund (each a series of Sit Mutual Funds II, Inc.) (collectively, the Funds), including the schedules of investments, as of March 31, 2015, 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 period in the five-year period then ended. These financial statements and financial highlights are the responsibility of 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, 2015, 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, Inc., Sit Quality Income Fund, Sit Tax-Free Income Fund, and Sit Minnesota Tax-Free Income Fund as of March 31, 2015, 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 the financial highlights for each of the years or period 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, 2014 to March 31, 2015.

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 (10/1/14)	Ending Account Value (3/31/15)		Expenses Paid During Period (10/1/14- 3/31/15)*
U.S. Government Securities Fund
Actual	$1,000		$1,014.10	$4.02
Hypothetical	$1,000		$1,020.94	$4.03
Quality Income Fund
Actual	$1,000		$998.90	$4.49
Hypothetical	$1,000		$1,020.44	$4.53
Tax-Free Income Fund
Actual	$1,000		$1,037.10	$4.06
Hypothetical	$1,000		$1,020.94	$4.03
Minnesota Tax-Free Income Fund
Actual	$1,000		$1,024.70	$4.04
Hypothetical	$1,000		$1,020.94	$4.03

*Expenses are equal to the Funds’ annualized expense ratio of 0.80% for the U.S. Government Securities, Tax-Free Income and Minne-sota Tax-Free Funds; and 0.90% for the Quality Income Fund, multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period.)

RE-APPROVAL OF INVESTMENT MANAGEMENT AGREEMENTS

At their joint meeting held on October 24, 2014, 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.

64 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 $14.35 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 compared each Fund’s expense ratio to the average and median expense ratios of no-load mutual funds within the same Morningstar, Inc. investment category, the average expense ratios for load funds within the Morningstar category, and the average expense ratios for all funds within the Morningstar category. Certain of the Fund’s expense ratios were higher than the averages, and certain of the Fund’s expense ratios were lower than the averages. The Directors noted that the Morningstar no-load categories include funds of various asset sizes, some of which are significantly larger in assets than the Funds. The Directors found that each Fund’s total expense ratio to be within an acceptable range compared to the total expense ratios of other no- load funds within the Fund’s 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 amount of the Funds’ current assets and the likelihood and magnitude of future increases in the Funds’ assets, negotiating a graduated fee structure is unnecessary at this time since the fees to be paid under the current Agreements are reasonable and appropriate.

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.

MARCH 31, 2015 65

ADDITIONAL INFORMATION (Unaudited) (Continued)

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.

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.
