CHAIRMAN’S LETTER

May 4, 2018

Dear fellow shareholders:

The last year provided fixed income investors much to chew on.

Although it still remains accommodative at present, the U.S. Federal Reserve (Fed) moved towards a more neutral monetary policy stance as they balance their dual mandates of inflation and unemployment. Economic growth was strong with quarterly ranges of 2.9-3.2% for the last three quarters of calendar 2017 after a modest increase of 1.2% in the first quarter of last year. Inflation approached the Fed’s target of 2% during the past year, while the labor market remains strong but has yet to fuel much inflation.

In Washington, D.C., policy makers passed a signature piece of legislation with the Tax Cut and Jobs Act (TCJA), the first significant tax reform in over 30 years for the United States. Combining TCJA with overall economic activity and both current and projected monetary policy changes, resulted in a significantly flatter yield curve.

Federal Reserve

The Fed moved to normalize monetary policy by accelerating the pace of short-term interest rate increases and initiating the removal of multiple rounds of quantitative easing that ultimately increased the size of the Fed’s balance sheet from modestly less than $1 trillion early in 2008 to approximately $4.5 trillion by 2015. Furthermore, the Fed experienced a change in leadership as President Trump nominated Jerome “Jay” Powell to replace Janet Yellen at the end of her term in February 2018.

In terms of raising rates, the Fed increased the Target Federal Funds Rate a total of three times in 2017 at its meetings in March, June, and December and once so far in 2018 at its March meeting, a marked increase in pace after a single 0.25% increase in the Target Federal Funds Rate each in 2016 and 2015. The current Federal Funds Target Rate is a range of 1.50-1.75% as of March 2018 versus the near-zero range of 0-0.25% as recently as November 2015. Remember, the Federal Funds rate is the rate at which banks lend excess reserves held at the Federal Reserve to other banks on an overnight basis. The Fed sets the target rate, which in turn is highly correlated with other short-term interest rates in fixed income markets.

The Fed first announced that it may begin reducing its balance sheet at its June 2017 meeting. Soon thereafter, at its September 2017 meeting, the Fed announced it would initiate this balance sheet normalization program in October 2017 by decreasing the reinvestment of principal payments from securities. The pace began slowly with a $10 billion balance sheet reduction in October 2017 but is scheduled to progressively increase to $50 billion per month by October 2018. The normalization of its balance sheet will take years, not months, but it does mark a return towards a more neutral policy stance.

With respect to the change in leadership at the Fed, Powell had previously served as the Fed’s Vice Chairman under Yellen and as a member of the Fed’s Board of Governors since 2012. The market generally expects Chairman Powell to continue on the path initiated by Chair Yellen, at least for the time being. However, it should be noted that Chairman Powell is not a career economist but rather has spent a significant portion of his career in the investment banking industry and a few years at the Treasury in addition to his experience

at the Fed. As a result, some market participants expect him to be modestly more pro-business in his stance than was Chair Yellen.

Tax Reform

Much of the political discourse in 2017 centered around tax reform. After a failed attempt at health care reform in the first half of 2017, policy makers moved towards tax reform. As the year progressed, market participants possessed varying degrees of confidence that some form of tax reform would pass. When the House passed its tax reform bill in mid-November 2017, the market became increasingly confident tax reform may pass by year end. Ultimately, the final version of tax reform was signed into law by President Trump on December 22, 2017.

Significant provisions of corporate tax reform included a reduction in the tax rate to 21% from 35%, a repatriation tax on foreign earnings of 8% (15.5% for cash), full expensing of most tangible non-real property for a limited time, and a repeal of the corporate alternative minimum tax. Individuals saw less significant tax changes including numerous bracket changes and modest rate decreases combined with an increase in the standard deduction to partially offset the elimination or reduction of many deductions. Tax reform should stimulate economic growth, at least over the near term. However, it will also significantly increase the deficit before accounting for any potential offsets from increased economic growth on future tax collections.

The initial version of tax reform passed by the House contained many concerning provisions for the tax-exempt segment of fixed income markets. Specifically, the initial House version contained a provision to eliminate private activity bonds as well as advanced refunding transactions. By late December many issuers had rushed to market over fears their tax-exempt status could be lost, resulting in record monthly municipal supply in excess of $60 billion in December 2017, topping the previous record of nearly $55 billion established in December 1985, just before the last version of tax reform was implemented. The final version passed and signed into law in late December did eliminate tax-exempt advanced refunding transactions but maintained the tax-exempt status of private activity bonds.

Yield Curve

The yield curve flattened dramatically over the last year as the Fed’s actions to raise short-term interest rates combined with confidence that the economy, aided by the recent fiscal stimulus from the TCJA, would remain on a solid growth trajectory for the short-to-intermediate term. Moreover, the yield curve was likely impacted by the expectation that the Fed continue a gradual pace of short-term rate increases throughout 2018 and into 2019.

The Fed’s balance sheet reduction also impacted the yield curve. The Fed had total maturities of $156 billion in the six months since starting balance sheet reduction and the Funds’ fiscal year-end in March versus a scheduled balance sheet reduction of $54 billion over the same time period, for net remaining reinvestment of $102 billion. Over 80% of the Fed’s $102 billion purchases over this time

2 SIT MUTUAL FUNDS ANNUAL REPORT

period were in new securities with maturities of 7 years or less. The balance sheet reduction over the last 6 months effectively increased the public supply of U.S. Treasury securities by $54 billion, 80% of which or approximately $43 billion was in maturities less than or equal to 7-years, contributing to shorter-term rates increasing relative to longer-term rates.

Specifically, the spread between 2-year and 30-year U.S. Treasury bonds decreased by over 1 percentage point over the last 12 months to 70 basis points at the end of March 2018 versus 175 basis points the previous March. This was achieved by a dramatic increase in short-term rates as the 2-year U.S. Treasury yield increased to 2.27% from 1.26% and a slight decrease in long-term rates as the 30-year U.S. Treasury yield decreased to 2.97% from 3.01%.

Strategy

We have positioned our funds to remain resilient in the face of continued increases in short-term interest rates and stable to modestly increasing longer-term interest rates. We believe that they are positioned to withstand rising interest rates 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 near all-time lows. The Sit

Quality Income Fund continues to focus on shorter than benchmark duration using a combination of government securities, predominantly agency MBS, combined with attractive short-term asset-backed securities, corporate bonds, and taxable municipal securities, including select floating rate securities.

The tax-exempt fixed income strategy for 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. Our investment strategy focuses on income, which is the primary source of return over longer periods of time. We believe that this will continue to deliver positive relative 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

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 +0.76% during the year ending March 31, 2018, compared to the return of the Bloomberg Barclays Intermediate Government Bond Index of -0.14%. The Fund’s 30-day SEC yield was 2.69% and its 12-month distribution rate was 1.67%.

During the 12-month period, the Fund benefited from the consistent relatively high level of income provided by its holdings in higher coupon government agency mortgages. The Fund uses Treasury options to reduce interest rate risk. The use of options was successful in providing stability to the Fund’s net asset value and contributed positively to the return. The Federal Reserve hiked the Fed Funds rate three times over the 12-month period as it continued to normalize monetary policy. In addition, the Federal Reserve began its plan to normalize its balance sheet. While the effects have been minimal, we believe the impact will be amplified in the upcoming year. We expect interest rates to move higher with short term rates outpacing long term rates. The new Federal Reserve Chairman, Jerome Powell, held his first press conference and was well received by investors. We expect the Federal Reserve to maintain a methodical approach for normalizing its balance sheet and gradually raising interest rates over time. The Fund’s high coupon mortgages should continue to produce an income advantage in this environment as prepayments are likely to remain stable or potentially slow.

We continue to position the Fund defensively against rising short-term interest rates while maintaining the Fund’s focus on seasoned, high coupon agency mortgage securities which provide a high level of income with relatively stable prices. This high level of income and stability of principal has been a fundamental focus of the Fund since its inception.

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 Bloomberg 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 Bloomberg Barclays Intermediate Government Bond Index is a sub-index of the Bloomberg Barclays Government Bond Index covering issues with remaining maturities of between three and five years. The Bloomberg 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.

FUND DIVERSIFICATION

Based on total net assets as of March 31, 2018. Subject to change.

PORTFOLIO SUMMARY
Net Asset Value 3/31/18:	$10.80 Per Share
Net Asset Value 3/31/17:	$10.90 Per Share
Total Net Assets:	$527.7 Million
Effective Duration3:	0.8 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.

ESTIMATED AVERAGE LIFE
0-1 Year	2.2	%
1-5 Years.	96.4
20+ Years	1.4

The table represents the Adviser’s estimates of the dollar weighted average life of the portfolio’s securities, which differ from their stated maturities. The Fund’s average stated maturity was 18.7 years as of March 31, 2018.

    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 and, 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 +0.79% during the 12-month period ending March 31, 2018, compared to the return of the Bloomberg Barclays 1-3 Year Government/Credit Bond Index of +0.24%. The Fund’s 30-day SEC yield was 2.08% and its 12-month distribution rate was 1.30%.

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. Nonagency residential mortgages outperformed as higher home prices increased demand for these securities. Taxable municipal securities also outperformed as their higher yields were attractive for investors. Corporate securities outperformed as future growth prospects continue to increase demand, causing yields to decrease relative to treasuries. The Fund uses Treasury futures and options to reduce interest rate risk. The use of futures and options was successful in providing stability to the Fund’s net asset value and contributed positively to the return. The Federal Reserve hiked the Fed Funds rate three times over the 12-month period as it continued to normalize monetary policy. In addition, the Federal Reserve began its plan to normalize its balance sheet. While the effects have been minimal, we believe the impact will be amplified in the upcoming year. We expect interest rates to move higher with short term rates outpacing long term rates. The new Federal Reserve Chairman, Jerome Powell, held his first press conference and was well received by investors. We expect the Federal Reserve to maintain a methodical approach for normalizing its balance sheet and gradually raising interest rates over time.

We have positioned the Fund defensively, in both credit quality and interest rate sensitivity to maximize return potential while preserving principal. We focus on a mix of Treasury, agency and credit sectors that provide relatively high levels of income and 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 Bloomberg 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 Bloomberg 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. This is the Fund’s primary index.

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 the periods greater than one year are compounded average annual rates of return.

PORTFOLIO SUMMARY

Net Asset Value 3/31/18:	$9.78 Per Share
Net Asset Value 3/31/17:	$9.83 Per Share
Total Net Assets:	$74.5 Million
Average Maturity:	9.3 Years
Effective Duration3:	0.9 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 return of +6.00% during the fiscal year ended March 31, 2018, versus a total return of +0.65% for the Bloomberg Barclays 5-Year Municipal Bond Index. As of March 31, 2018, the Fund’s 30-day SEC yield was 2.80% and the Fund’s 12-month distribution rate was 4.06%.

The tax-exempt yield curve flattened significantly during the past year driven primarily by rising yields for shorter maturities. Yields for maturities less than three years increased by approximately 60-70 basis points while yields for intermediate maturities increased approximately 30-50 basis points. In contrast, yields for long maturities decreased by approximately 10 basis points. Fund flows into tax-exempt mutual funds were strong throughout the fiscal year, totaling approximately $30 billion. Tax-exempt issuance rose to $62 billion in December, which was a record for that month, after averaging approximately $32 billion over the first 8 months of the fiscal year. The spike in issuance was caused by federal tax reform proposals which would have eliminated the tax exemption for private activity bonds and prohibited tax-exempt advanced refunding of municipal bonds. While the private activity bond tax-exemption was ultimately retained in the enacted legislation, tax-exempt advanced refunding of municipal bonds was eliminated. Issuance was substantially lower in the first quarter of 2018 because borrowers pulled forward some of their planned 2018 issuance into December to preempt these tax reform proposals which were scheduled to become effective January 2018.

The Fund significantly outperformed its benchmark over the last year due to several factors. The Fund maintained a larger weighting of long duration bonds relative to the benchmark. This strategy was advantageous as bonds on the long end of the curve outperformed shorter bonds while the yield curve flattened. In addition, we began hedging the portfolio in April 2017 using U.S. Treasury futures to shorten duration in anticipation of rising interest rates. This hedging strategy was beneficial to the Fund’s performance between November and February and contributed approximately 50 basis points to the Fund’s outperformance. The Fund’s credit quality distribution produced a favorable outcome. At the end of the fiscal year, the Fund held 28% of net assets in bonds rated single-A or lower and 21% in non-rated bonds while the Bloomberg Barclays 5-Year Municipal Bond Index is predominately comprised of AA-rated bonds or higher. These lower rated and non-rated bonds outperformed their higher rated peers over the past year. Finally, good security selection in the single- and multi-family housing sectors, which represent our largest weightings, contributed meaningfully to the Fund’s outperformance.

        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 Bloomberg 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 Bloomberg 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.

Our investment strategy continues to emphasize current income as the primary driver of returns over the long-run. We expect to continue hedging to maintain duration close to that of the Fund’s benchmark, but we will remain prepared to adjust this position as market conditions warrant. We also anticipate continuing to utilize housing bonds for their incremental yield over comparably-rated issuers as well as non-rated bonds in the Fund. Our strategy will rely on rigorous credit analysis to identify favorable investment opportunities. We remain diversified across industries and issuers to manage credit and liquidity risk, and we believe the Fund is well positioned to achieve attractive risk-adjusted returns going forward.

Average Maturity:	17.2 Years
Effective Duration3:	4.2   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 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 return of +4.08% during the fiscal year ended March 31, 2018, versus a total return of +0.65% for the Bloomberg Barclays 5-Year Municipal Bond Index. As of March 31, 2018, the Fund’s 30-day SEC yield was 2.80% and the Fund’s 12-month distribution rate was 3.04%.

Minnesota’s economy strengthened over the last 12 months. The unemployment rate declined to 3.2% and remains below the 4.1% national rate as of March 2018. Minnesota’s tax revenue grew 4.3% fiscal year-to-date through December, supported by ongoing employment growth.

The tax-exempt yield curve flattened significantly during the past year driven primarily by rising yields for shorter maturities. Yields for maturities less than three years increased by approximately 60-70 basis points while in contrast, yields for long maturities decreased by approximately 10 basis points. Fund flows into tax-exempt mutual funds were strong throughout the fiscal year. Tax-exempt issuance rose to $62 billion in December, which was a record for that month. The spike in issuance was caused by federal tax reform proposals which would have eliminated the tax exemption for private activity bonds and prohibited tax-exempt advanced refunding of municipal bonds. While the private activity bond tax-exemption was ultimately retained in the enacted legislation, tax-exempt advanced refunding of municipal bonds was eliminated. Issuance was substantially lower in the first quarter of 2018 because borrowers pulled forward some of their planned 2018 issuance into December to preempt these tax reform proposals which were scheduled to become effective January 2018. Supply of Minnesota tax-exempt bonds was lower than in recent years but sufficient for us to find attractive investment opportunities for the Fund.

The Fund significantly outperformed its benchmark over the last year due to several factors. The Fund maintained a larger weighting of long duration bonds relative to the benchmark. This strategy was advantageous as bonds on the long end of the curve outperformed shorter bonds while the yield curve flattened. In addition, we began hedging the portfolio in April 2017, using U.S. Treasury futures to shorten duration in anticipation of rising interest rates. This hedging strategy was beneficial to the Fund’s performance between November and February and contributed approximately 40 basis points to the Fund’s outperformance. The Fund’s utilization of non-rated bonds was also favorable. At the end of the fiscal year, the Fund held 27% of net assets in non-rated bonds and these bonds outperformed

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 Bloomberg 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 Bloomberg 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.

their rated peers over the past year. Finally, good security selection in the multi-family housing, healthcare, and education sectors contributed meaningfully to the Fund’s outperformance.

Our investment strategy continues to emphasize current income as the primary driver of returns over the long-run. We expect to continue hedging to maintain duration close to that of the Fund’s benchmark, but we will remain prepared to adjust this position as market conditions warrant. We also anticipate continuing to utilize housing bonds for their incremental yield over comparably-rated issuers as well as non-rated bonds in the Fund.

We believe the Fund is well positioned to achieve attractive risk-adjusted returns going forward.

Average Maturity:	15.9 Years
Effective Duration3:	4.4 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, 2018

(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. Equity 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.

56 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 Funds used Treasury options and futures traded on a U.S. exchange. Risks of entering into futures and options contracts 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, a 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, 2018, the average volume of derivative activity, calculated on a quarterly basis, was as follows:

	Average Cost		Average Premium Received		Average Notional Amount
U.S. Government Securities Fund
Purchased put options		$452,814		—		$215,757,750
Written call options		—		$2,298,264		461,260,825

Treasury futures		—		—		31,753,494
Tax-Free Income Fund
Treasury futures		—		—		42,944,029
Minnesota Tax-Free Income Fund
Treasury futures		—		—		80,496,048

The number of open option contracts and open futures contracts outstanding as of March 31, 2018 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.

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, 2018 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 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, 2018, no provision for income tax would be required in the Funds’ financial statements. The Funds’ federal and state income and federal excise tax returns remain subject to examination by the Internal Revenue Service and state departments of revenue until such time as the applicable statute of limitations for audit has expired. For example, U.S. tax returns are generally subject to audit for three years from the date they are filed.

As of March 31, 2018 the components of distributable earnings on a tax basis were as follows:

											Unrealized
	Undistributed			Undistributed			Accumulated				Appreciation
	Ordinary Income			Tax-Exempt Income			Gain (Loss)				(Depreciation)
U.S. Government Securities		$	145,211			—		($	13,289,160	)		($	4,542,687	)

60 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		Accumulated
	Net Investment		Net Realized			Additional
	Income		Gain (Loss)			Paid-in Capital
Tax-Free Income		($831)		$	6,322,868		($	6,322,037	)
Minnesota Tax-Free Income		4,322			3,531,341			(3,535,663	)

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, 2018, are available to offset future realized capital gains and thereby reduce future capital gains distributions. The Funds are permitted to carry forward capital losses for an unlimited period. Capital losses that are carried forward retain their character as either short-term or long-term capital losses. The net capital loss carryovers and the expiration dates for capital loss carryovers from pre-enactment taxable years and the late year losses deferred as of March 31, 2018, were as follows:

	Pre-Enactment
	Net Capital Loss					Unlimited Period of Net						Late Year		Accumulated
	Carryover Expiring in:					Capital Loss Carryover						Losses		Capital and
	2018		2019			Short-Term			Long-Term			Deferred		Other Losses

For the year ended March 31, 2018, the Funds’ utilized capital losses and expired capital losses as follows:

	Utilized			Expired
U.S. Government Securities		$	2,813,612	—
Quality Income			264,984	—
Tax-Free Income			361,962	$6,322,037
Minnesota Tax-Free Income			1,521,985	3,535,663

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors:

Sit U.S. Government Securities Fund, Inc.

Sit Mutual Funds II, Inc.:

Opinion on the Financial Statements

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, 2018, 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 related notes (collectively, the financial statements) and the financial highlights for each of the years or periods in the five-year period then ended. In our opinion, the financial statements and financial highlights present fairly, in all material respects, the financial position of the Funds as of March 31, 2018, 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 periods in the five-year period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

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 are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Funds in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. 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, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements and financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements and financial highlights. Such procedures also included confirmation of securities owned as of March 31, 2018, by correspondence with custodians and brokers. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and financial highlights. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more Sit Mutual Funds investment companies since 1982.

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, 2017 to March 31, 2018.

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 (10/1/17)		Ending Account Value (3/31/18)		Expenses Paid During Period (10/1/17- 3/31/18)*
U.S. Government Securities Fund
Actual		$1,000		$1,001.10	$3.99
Hypothetical		$1,000		$1,020.94	$4.03
Quality Income Fund
Actual		$1,000		$1,000.90	$4.49
Hypothetical		$1,000		$1,020.44	$4.53
Tax-Free Income Fund
Actual		$1,000		$1,022.10	$4.03
Hypothetical		$1,000		$1,020.94	$4.03
Minnesota Tax-Free Income Fund
Actual		$1,000		$1,010.30	$4.01
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 Minnesota 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 23, 2017, 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 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.

68 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 $13.8 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 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.

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.

Audit-related fees include amounts reasonably related to the performance of the audit of the registrant’s financial statements, and/or are traditionally performed by the auditor. Tax fees include amounts related to tax compliance, tax planning, and tax advice.

(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.
