Chairman’s Letter

to Shareholders

Dear Shareholders,

Whether politics or the economy will prevail over the financial markets this year has been a much-analyzed question. After the U.S. presidential election, stocks rallied to new all-time highs, bonds tumbled, and business and consumer sentiment grew pointedly optimistic. But, to what extent the White House can translate rhetoric into stronger economic and corporate earnings growth remains to be seen. Stock prices have experienced upward momentum driven by positive economic news, interest rates are higher amid the Federal Reserve (Fed) rate hikes and inflation is ticking higher.

The Trump administration’s early policy decisions have caused the markets to reassess their outlooks, cooling the stock market rally and stabilizing bond prices. The White House’s pro-growth agenda of tax reform, infrastructure spending and deregulation remains on the table, but there is growing recognition that it may look different than Wall Street had initially expected.

Nevertheless, there is a case for optimism. The jobs recovery, firming wages, the housing market and confidence measures are supportive of continued expansion in the economy. The Fed enacted its second and third interest rate hikes in December 2016 and March 2017, respectively, a vote of confidence that its employment and inflation targets are on track. Economies outside the U.S. have strengthened in recent months, possibly heralding the beginnings of a global synchronized recovery. Furthermore, the populist/nationalist undercurrent that helped deliver President Trump’s win and the U.K.’s decision to leave the European Union (or “Brexit”) remained in the minority in the Dutch general election in March and France’s presidential election in May, easing the political uncertainty surrounding Germany’s elections later this year.

In the meantime, the markets will be focused on economic sentiment surveys along with “hard” data such as consumer and business spending to gauge the economy’s progress. With the Fed now firmly in tightening mode, rate moves that are more aggressive than expected could spook the markets and potentially stifle economic growth. On the political economic front, President Trump’s other signature platform plank, protectionism, is arguably anti-growth. We expect some churning in the markets as these issues sort themselves out.

Market volatility readings have been remarkably low of late, but conditions can change quickly. As market conditions evolve, Nuveen remains committed to rigorously assessing opportunities and risks. If you’re concerned about how resilient your investment portfolio might be, we encourage you to talk to your financial advisor. On behalf of the other members of the Nuveen Fund Board, we look forward to continuing to earn your trust in the months and years ahead.

Sincerely,

William J. Schneider

Chairman of the Board

Nuveen Symphony Credit Opportunities Fund

Nuveen Symphony Floating Rate Income Fund

Nuveen Symphony High Yield Bond Fund

The Fund’s portfolios are managed by Symphony Asset Management LLC, (Symphony), an affiliate of Nuveen, LLC. Gunther Stein, Chief Investment Officer and Chief Executive Officer at Symphony and Jenny Rhee manage the Nuveen Symphony Credit Opportunities Fund and the Nuveen Symphony High Yield Bond Fund, while Gunther and Scott Caraher oversee the investments of the Nuveen Symphony Floating Rate Income Fund.

Here they discuss key investment strategies and performance of the Funds for the six-month reporting period ended March 31, 2017.

How did the Funds perform during the six-month reporting period ended March 31, 2017?

The tables in the Fund Performance and Expense Ratios section of this report provide total return performance information for the Funds for the six-month, one-year, five-year and/or since inception periods ended March 31, 2017. Each Fund’s Class A Share total returns at net asset value (NAV) are compared with the performance of its comparative market index and Lipper classification average. A more detailed account of each Fund’s performance is provided later in this report.

What was the primary investment strategy for each Fund and how did this strategy affect the Fund’s performance for the six-month reporting period ended March 31, 2017?

Our investment process for the Nuveen Symphony Credit Opportunities Fund, the Nuveen Symphony Floating Rate Income Fund and the Nuveen Symphony High Yield Bond Fund is based upon fundamental, bottom-up credit analysis. After assessing sector dynamics, company business models and asset quality, our analysts make specific recommendations based on the relative value of the various types of debt within a company’s capital structure. We evaluate the potential upside and downside to any credit and concentrate our efforts on sectors with sufficient transparency to assess the downside risk and in firms that have enough assets to support meaningful recovery in case of default.

All of these Funds have owned, or currently own, loans with the London Inter-Bank Offered Rate (LIBOR) floor feature. The coupon on most senior loans consists of both LIBOR (usually 90-day U.S. LIBOR) plus a spread. For example, a senior loan might have a coupon structure of “LIBOR plus 400 basis points (bp)” in which the coupon consists of 90-day LIBOR, plus 400bp. Given today’s relatively low LIBOR rate, however, many issuers have put in place LIBOR floors to enhance the yield (and satisfy demand from investors) for newly issued loans. LIBOR floors, as the name suggests, put a “floor” on the reference LIBOR rate. LIBOR floors typically range from 150bp to 50bp. A loan with a LIBOR floor might have a structure of “LIBOR + 400bp with a 100bp LIBOR floor.” In this example, the effective coupon is 5% (100bp + 400bp as long as LIBOR is less than or equal to 100bp). As a result, as LIBOR rises from current levels, the yield on a senior loan with a LIBOR floor will not rise in lockstep until after the reference LIBOR rate exceeds the LIBOR floor. Although many loans have LIBOR floors (the asset class is one of the few that will float when interest rates begin to

Portfolio Managers’ Comments (continued)

rise), we believe the senior loan asset class provides fixed income oriented investors with a potential safeguard from a secular rise in interest rates.

Nuveen Symphony Credit Opportunities Fund

The Fund’s Class A Shares at NAV outperformed the BofA/Merrill Lynch U.S. High Yield Master II Index, the Custom Benchmark Index and the Lipper High Yield Funds Classification Average during the reporting period.

The Fund seeks current income and capital appreciation by investing primarily in debt instruments such as bonds, loans and convertible securities, a substantial portion of which may be rated below investment grade or, if unrated, of comparable quality. As of the end of the reporting period, the Fund’s portfolio had 12.7% senior loans and 81.0% high yield bonds. The Fund may utilize derivatives, including options, futures contracts, options on futures contracts, swap agreements, including interest rate swaps, total return swaps and credit default swaps and options on swap agreements.

Several factors contributed to the Fund’s outperformance during the reporting period. All sectors positively contributed to performance, with the exception of the financials and consumer staples sectors. In particular, the corporate bonds of consumer discretionary holdings Scientific Games Corporation contributed to performance. The leading provider of gaming and lottery systems rallied on the combination of a strong high yield market, improving operating gains and the company’s buyback of unsecured debt. We believe the company will benefit further from its corporate restructuring and continue to own the bonds. Also positively contributing were the bonds of telecommunication services holding Intelsat, S.A. The satellite company strongly benefitted returns as the company’s bonds rose on the announcement of a merger with a peer company. Lastly, the bonds of consumer discretionary holdings Channel Communications, Inc., a leading global media and entertainment company, also contributed to performance. The company traded higher as risk assets continued their rally. The company continued to post marginally improving numbers and also announced a comprehensive plan to reduce debt. While the debt deal is far from final, the news was well received by the market as an indicator that the firm is willing to negotiate to find a more permanent solution for its highly levered balance sheet.

Several factors detracted from the Fund’s performance, including the loans of consumer discretionary holding Gymboree Corporation. The bonds and loans of the retail company weighed on returns as poor execution by management compounded by a competitive retail environment led to weakened earnings results announced during the reporting period. Ultimately, we believe the company will be able to reject certain leases during bankruptcy and reemerge with a healthier balance sheet. Also detracting from performance were the loans of consumer discretionary holding Education Management Corporation, which is one of the largest providers of post-secondary education in the United States. For-profit colleges have struggled to rebound from heightened government regulation. The corporation has closed many of its campuses in recent years and continues to struggle. We continue to hold the position as the team believes there is residual value to be realized in the name. Lastly, the bonds of energy holding Cobalt International Inc. detracted from performance. During the reporting period, the company completed a debt exchange and financing transaction that raised $500 million of liquidity and extended its debt out for an additional four years. In addition, a deal for its Angolan assets fell through which has put additional pressure on the company to produce results. We continue to hold the position as we believe markets to be supportive of energy names.

Nuveen Symphony Floating Rate Income Fund

The Fund’s Class A Shares at NAV outperformed the Credit Suisse Leveraged Loan Index and the Lipper Loan Participation Funds Classification Average during the reporting period.

The Fund seeks current income and capital appreciation by investing primarily in floating rate loans and other floating rate securities, a substantial portion of which will be rated below investment grade. The Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in floating rate securities. Floating rate securities are defined to include floating rate loans, other floating rate debt securities, money market securities and shares of money market and short-term bond funds. The Fund may invest up to 20% of its net assets in other securities, which would primarily be fixed rate debt securities, convertible securities and equity securities received as a result of the restructuring of an issuer’s debt. A substantial portion of the Fund’s assets generally will be invested in securities rated below investment grade or, if unrated, deemed to be of comparable quality. The Fund may utilize derivatives, including options, futures contracts, options on futures contracts, swap agreements, including interest rate swaps, total return swaps, credit default swaps and options on swap agreements.

During the reporting period, the Fund’s capital was deployed into assets that we believe offered attractive current income and yield for the associated risk profile. Fundamentally, we believe that many of these companies have stable businesses, good asset coverage for senior debt holders and may perform well in a stable to slow-growth environment.

Several factors contributed to the Fund’s outperformance during the reporting period. All sectors positively contributed to performance, with the exception of the financials sector. Positively contributing were the bonds of telecommunication services holding Intelsat, S.A. The satellite company strongly benefitted returns as the company’s bonds rose on the announcement of a merger with a peer company. In addition, the bonds of consumer discretionary holdings Channel Communications, Inc., a leading global media and entertainment company, also contributed to performance. The company traded higher as risk assets continued their rally. The company continued to post marginally improving numbers and also announced a comprehensive plan to reduce debt. While the debt deal is far from final, the news was well received by the market as an indicator that the firm is willing to negotiate to find a more permanent solution for its highly levered balance sheet. Lastly, holdings in the consumer discretionary sector position of Scientific Games Corporation contributed to performance. The leading provider of gaming and lottery systems rallied on the combination of high yield market momentum, modest operating gains and the company’s buyback of unsecured debt. We believe the company will benefit further from its corporate restructuring and continue to own the bonds.

Several factors detracted from the Fund’s performance, including the loans of consumer discretionary holding Gymboree Corporation. The loans of the retail company weighed on returns as a weak retail environment led to weakened earnings results announced during the reporting period. Ultimately, we believe the company will be able to reject certain leases during bankruptcy and reemerge with a healthier balance sheet. In addition, the loans of consumer discretionary holding, Cengage Learning Acquisitions Inc. also detracted from performance. The firm took leverage up earlier in 2016, and then posted weaker than expected numbers which was ill received by the market. We feel that earnings will normalize longer term and that the underlying collateral mitigates the downside risk to the loan. Lastly, the loans of a diversified mortgage banking firm Walter Investment Management Corp., which focuses primarily on servicing and originating residential loans, detracted from performance. The company reported worse than expected fourth quarter 2016 losses, discussed challenges to reducing its leverage and continues to face a number of regulatory issues. Ultimately, we believe there is asset coverage for the loan and the company will eventually negotiate with lenders for covenant relief that would allow the company additional flexibility within the capital structure.

Nuveen Symphony High Yield Bond Fund

The Fund’s Class A Shares at NAV outperformed both the BofA/Merrill Lynch U.S. High Yield Master II Index and the Lipper High Yield Funds Classification Average during the reporting period.

The Fund seeks current income and capital appreciation by investing primarily in below investment grade bonds using a bottom up, research driven process. The Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in bonds rated below investment grade or, if unrated, of comparable quality. The Fund may invest up to 20% of its net assets, collectively, in bank loans, convertible securities and equity securities. We base our investment process on fundamental, bottom-up credit analysis. After assessing sector dynamics, company business models and asset quality, our analysts make specific recommendations based on the relative value of the various types of debt within a company’s capital structure. We concentrate our efforts on sectors with sufficient transparency to assess the downside risk and in firms with enough assets to support meaningful recovery in case of default. Our focus on downside risk management favors opportunities wherein valuations can be quantified and risks assessed. The Fund may utilize derivatives, including options, futures contracts, options on futures contracts, swap agreements, including interest rate swaps, total return swaps, credit default swaps and options on swap agreements.

Several factors contributed to the Fund’s outperformance during the reporting period. Most sectors contributed positively to performance, with the exception of the consumer staples, health care and financials sectors. The holdings in consumer discretionary position Scientific Games Corporation contributed to performance. The leading provider of gaming and lottery systems rallied on the combination of a strong high yield market, improving operating gains and the company’s buyback of unsecured debt. We believe the company will benefit further from its corporate restructuring and continue to own the bonds. Also within the telecommunications sector, a holding in a wireless service company, Syniverse Telecommunications Company, performed well, as the company posted strong operating results. Lastly, the bonds of telecommunication services holding Intelsat, S.A. contributed to performance. The satellite company strongly benefitted returns as the company’s bonds rose on the announcement of a merger with a peer company.

Portfolio Managers’ Comments (continued)

Those holdings that detracted from the Fund’s performance included the loans of consumer discretionary holding Gymboree Corporation. The bonds and loans of the retail company weighed on returns as poor execution by management compounded by a competitive retail environment led to weakened earnings results announced during the reporting period. The loans of consumer discretionary holding J. Crew Group, Inc. detracted also from performance. The company has seen several quarters of declining sales as the company continues to struggle with its brand momentum. We believe that at current levels the loans could potentially benefit from a restructuring, possibly in the near term. Lastly, the bonds of a diversified mortgage banking firm Walter Investment Management Corp., which focuses primarily on servicing and originating residential loans, detracted from performance. The company reported worse than expected fourth quarter 2016 losses, discussed challenges to reducing its leverage and continues to face a number of regulatory issues. Ultimately, we believe there is asset coverage for the loan and the company will eventually negotiate with lenders for covenant relief that would allow the company additional flexibility within the capital structure.

Risk Considerations

and Dividend Information

Risk Considerations

Nuveen Symphony Credit Opportunities Fund

Mutual fund investing involves risk; principal loss is possible. Debt or fixed income securities such as those held by the Fund, are subject to market risk, credit risk, interest rate risk, derivatives risk, liquidity risk, and income risk. As interest rates rise, bond prices fall. Below investment grade or high yield debt securities are subject to liquidity risk and heightened credit risk. Foreign investments involve additional risks, including currency fluctuation, political and economic instability, lack of liquidity and differing legal and accounting standards. The value of the Fund’s convertible securities may decline in response to such factors as rising interest rates and fluctuations in the market price of the underlying securities. This Fund is subject to loan settlement risk due to the lack of established settlement standards or remedies for failure to settle.

Nuveen Symphony High Yield Bond Fund

Mutual fund investing involves risk; principal loss is possible. Debt or fixed income securities such as those held by the Fund, are subject to market risk, credit risk, interest rate risk, call risk, derivatives risk, liquidity risk, income risk and bond market liquidity risk which is the risk that Fund performance can be negatively affected if the Fund must sell securities at lower prices due to decreased market liquidity and increased price volatility when primary dealers of bonds have low inventories relative to the overall fixed income markets. As interest rates rise, bond prices fall. Below investment grade or high yield debt securities are subject to liquidity risk and heightened credit risk. Foreign investments involve additional risks, including currency fluctuation, political and economic instability, lack of liquidity and differing legal and accounting standards. Because the Fund currently has less assets than a larger Fund, large inflows and outflows may impact the Fund’s market exposure and subsequently its performance. Redemption of a large number of shares may subject the Fund and its shareholders to leverage risk and disrupt the overall composition of the Fund’s portfolio and thereby impede the ability to pursue the investment strategy.

Dividend Information

Each Fund seeks to pay regular monthly dividends out of its net investment income at a rate that reflects its past and projected net income performance. To permit a Fund to maintain a more stable monthly dividend, the Fund may pay dividends at a rate that may be more or less than the amount of net income actually earned by the Fund during the period. If a Fund has cumulatively earned more than it has paid in dividends, it will hold the excess in reserve as undistributed net investment income (UNII) as part of the Fund’s net asset value. Conversely, if the Fund has cumulatively paid in dividends more than it has earned, the excess will constitute a negative UNII that will likewise be reflected in the Fund’s net asset value. Each Fund will, over time, pay all its net investment income as dividends to shareholders.

As of March 31, 2017, the Funds had positive UNII balances, based upon our best estimate, for tax purposes and negative UNII balances for financial reporting purposes.

Risk Considerations and Dividend Information (continued)

All monthly dividends paid by each Fund during the current reporting period were paid from net investment income. If a portion of the Fund’s monthly distributions was sourced from or comprised of elements other than net investment income, including capital gains and/or a return of capital, shareholders would have received a notice to that effect. For financial reporting purposes, the composition and per share amounts of each Fund’s dividends for the reporting period are presented in this report’s Statement of Changes in Net Assets and Financial Highlights, respectively. For income tax purposes, distribution information for each Fund as of its most recent tax year end is presented in Note 6 – Income Tax Information within the Notes to Financial Statements of this report.

Fund Performance

and Expense Ratios

The Fund Performance and Expense Ratios for each Fund are shown within this section of the report.

Returns quoted represent past performance, which is no guarantee of future results. Investment returns and principal value will fluctuate so that when shares are redeemed, they may be worth more or less than their original cost. Current performance may be higher or lower than the performance shown. Total returns for a period of less than one year are not annualized. Returns at net asset value (NAV) would be lower if the sales charge were included. Returns assume reinvestment of dividends and capital gains. For performance, current to the most recent month-end visit Nuveen.com or call (800) 257-8787.

Returns do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares.

Returns may reflect fee waivers and/or expense reimbursements by the investment adviser during the periods presented. If any such waivers and/or reimbursements had not been in place, returns would have been reduced. See Notes to Financial Statements, Note 7—Management Fees and Other Transactions with Affiliates for more information.

Returns reflect differences in sales charges and expenses, which are primarily differences in distribution and service fees, and assume reinvestment of dividends and capital gains.

Comparative index and Lipper return information is provided for Class A Shares at NAV only.

The expense ratios shown reflect total operating expenses (before fee waivers and/or expense reimbursements, if any) as shown in the most recent prospectus. The expense ratios include management fees and other fees and expenses.

Class A Shares have a maximum 4.75% sales charge (Offering Price). Class A Share purchases of $1 million or more are sold at net asset value without an up-front sales charge but may be subject to a contingent deferred sales charge (CDSC) of 1% if redeemed within eighteen months of purchase. Class C Shares have a 1% CDSC for redemptions within less than twelve months, which is not reflected in the one-year total return. Class R6 Shares have no sales charge and are available only to certain limited categories of investors as described in the prospectus. Class I Shares have no sales charge and may be purchased under limited circumstances or by specified classes of investors.

The Fund’s investment adviser has contractually agreed to waive fees and/or reimburse expenses through January 31, 2018, so that total annual Fund operating expenses (excluding 12b-1 distribution and/or service fees, interest expenses, taxes, acquired fund fees and expenses, fees incurred in acquiring and disposing of portfolio securities and extraordinary expenses) do not exceed 0.79% of the average daily net assets of any class of Fund shares. However, because Class R6 Shares are not subject to sub-transfer agent and similar fees, the total annual operating expenses for the Class R6 Shares will be less than the expenses limitation. This expense limitation may be terminated or modified prior to that date only with the approval of the Board of Trustees of the Fund.

Yields as of March 31, 2017

Dividend Yield is the most recent dividend per share (annualized) divided by the offering price per share.

The SEC 30-Day Yield is a standardized measure of a Fund’s yield that accounts for the future amortization of premiums or discounts of bonds held in the fund’s portfolio. The SEC 30-Day Yield is computed under an SEC standardized formula and is based on the maximum offer price per share. Subsidized yields reflect fee waivers and/or expense reimbursements from the investment adviser during the period. If any such waivers and/or reimbursements had not been in place, yields would have been reduced. Unsubsidized yields do not reflect waivers and/or reimbursements from the investment adviser during the period. Refer to the Notes to Financial Statements, Note 7 – Management Fees and Other Transactions with Affiliates for further details on the investment adviser’s most recent agreement with the Fund to waive fees and/or reimburse expenses, where applicable. Dividend Yield may differ from the SEC 30-Day Yield because the fund may be paying out more or less than it is earning and it may not include the effect of amortization of bond premium.

1 The SEC Yield for Class A shares quoted in the table reflects the maximum sales load. Investors paying a reduced load because of volume discounts, investors paying no load because they qualify for one of the several exclusions from the load, and existing shareholders who previously paid a load but would like to know the SEC Yield applicable to their shares on a going-forward basis, should understand that the SEC Yield effectively applicable to them would be higher than the figure quoted in the table.

Expense

Examples

As a shareholder of one or more of the Funds, you incur two types of costs: (1) transaction costs, including up-front and back-end sales charges (loads) or redemption fees, where applicable; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees, where applicable; and other Fund expenses. The Examples below are 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 Examples below are based on an investment of $1,000 invested at the beginning of the period and held through the period ended March 31, 2017.

The beginning of the period is October 1, 2016.

The information under “Actual Performance,” together with the amount you invested, allows you to estimate actual expenses incurred over the reporting period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.60) and multiply the result by the cost shown for your share class, in the row entitled “Expenses Incurred During Period” to estimate the expenses incurred on your account during this period.

The information under “Hypothetical Performance,” provides information about hypothetical account values and hypothetical expenses based on each Fund’s actual expense ratios 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 expense you incurred 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 tables are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the hypothetical information is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds or share classes. In addition, if these transaction costs were included, your costs would have been higher.

For Fund portfolio compliance purposes, the Fund’s industry classifications refer to any one or more of the industry sub-classifications used by one or more widely recognized market indexes or ratings group indexes, and/or as defined by Fund management. This definition may not apply for purposes of this report, which may combine industry sub-classifications into sectors for reporting ease.

(1) All percentages shown in the Portfolio of Investments are based on net assets.

(2) For fair value measurement disclosure purposes, investment classified as Level 2. See Notes to Financial Statements, Note 2 – Investment Valuation and Fair Value Measurements for more information.

(3) Non-income producing; issuer has not declared a dividend within the past twelve months.

(4) Investment valued at fair value using methods determined in good faith by, or at the discretion of, the Board. For fair value measurement disclosure purposes, investment classified as Level 3. See Notes to Financial Statements, Note 2 – Investment Valuation and Fair Value Measurements for more information.

(5) For financial reporting purposes, the ratings disclosed are the highest of Standard & Poor’s Group (“Standard & Poor’s”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch, Inc. (“Fitch”) rating. This treatment of split-rated securities may differ from that used for other purposes, such as for Fund investment policies. Ratings below BBB by Standard & Poor’s, Baa by Moody’s or BBB by Fitch are considered to be below investment grade. Holdings designated N/R are not rated by any of these national rating agencies.

(6) As of, or subsequent to, the end of the reporting period, this security is non-income producing. Non-income producing, in the case of a fixed-income security, generally denotes that the issuer has (1) defaulted on the payment of principal or interest, (2) is under the protection of the Federal Bankruptcy Court or (3) the Fund’s Adviser has concluded that the issue is not likely to meet its future interest payment obligations and has ceased accruing additional income on the Fund’s records.

(7) Senior loans generally pay interest at rates which are periodically adjusted by reference to a base short-term, floating lending rate plus an assigned fixed rate. These floating lending rates are generally (i) the lending rate referenced by the London Inter-Bank Offered Rate (“LIBOR”), or (ii) the prime rate offered by one or more major United States banks. Senior loans may be considered restricted in that the Fund ordinarily is contractually obligated to receive approval from the agent bank and/or borrower prior to the disposition of a senior loan. The rate shown is the coupon as of the end of the reporting period.

(8) Senior loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentives for a borrower to prepay, prepayments of senior loans may occur. As a result, the actual remaining maturity of senior loans held may be substantially less than the stated maturities shown.

(WI/DD) Purchased on a when-issued or delayed delivery basis.

PIK All or a portion of this security is payment-in-kind

144A Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.

TBD Senior loan purchased on a when-issued or delayed-delivery basis. Certain details associated with this purchase are not known prior to the settlement date of the transaction. In addition, senior loans typically trade without accrued interest and therefore a coupon rate is not available prior to settlement. At settlement, if still unknown, the borrower or counterparty will provide the Fund with the final coupon rate and maturity date.

See accompanying notes to financial statements.

For Fund portfolio compliance purposes, the Fund’s industry classifications refer to any one or more of the industry sub-classifications used by one or more widely recognized market indexes or ratings group indexes, and/or as defined by Fund management. This definition may not apply for purposes of this report, which may combine industry sub-classifications into sectors for reporting ease.

(1) All percentages shown in the Portfolio of Investments are based on net assets.

(2) For fair value measurement disclosure purposes, investment classified as Level 2. See Notes to Financial Statements, Note 2 – Investment Valuation and Fair Value Measurements for more information.

(3) Non-income producing; issuer has not declared a dividend within the past twelve months.

(4) For financial reporting purposes, the ratings disclosed are the highest of Standard & Poor’s Group (“Standard & Poor’s”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch, Inc. (“Fitch”) rating. This treatment of split-rated securities may differ from that used for other purposes, such as for Fund investment policies. Ratings below BBB by Standard & Poor’s, Baa by Moody’s or BBB by Fitch are considered to be below investment grade. Holdings designated N/R are not rated by any of these national rating agencies.

(5) Senior loans generally pay interest at rates which are periodically adjusted by reference to a base short-term, floating lending rate plus an assigned fixed rate. These floating lending rates are generally (i) the lending rate referenced by the London Inter-Bank Offered Rate (“LIBOR”), or (ii) the prime rate offered by one or more major United States banks. Senior loans may be considered restricted in that the Fund ordinarily is contractually obligated to receive approval from the agent bank and/or borrower prior to the disposition of a senior loan. The rate shown is the coupon as of the end of the reporting period.

(6) Senior loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentives for a borrower to prepay, prepayments of senior loans may occur. As a result, the actual remaining maturity of senior loans held may be substantially less than the stated maturities shown.

(7) As of, or subsequent to, the end of the reporting period, this security is non-income producing. Non-income producing, in the case of a fixed-income security, generally denotes that the issuer has (1) defaulted on the payment of principal or interest, (2) is under the protection of the Federal Bankruptcy Court or (3) the Fund’s Adviser has concluded that the issue is not likely to meet its future interest payment obligations and has ceased accruing additional income on the Fund’s records.

(DD1) Portion of investment purchased on a delayed delivery basis.

(WI/DD) Purchased on a when-issued or delayed delivery basis.

PIK All or portion of this security is payment-in-kind.

144A Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.

TBD Senior loan purchased on a when-issued or delayed-delivery basis. Certain details associated with this purchase are not known prior to the settlement date of the transaction. In addition, senior loans typically trade without accrued interest and therefore a coupon rate is not available prior to settlement. At settlement, if still unknown, the borrower or counterparty will provide the Fund with the final coupon rate and maturity date.

See accompanying notes to financial statements.

For Fund portfolio compliance purposes, the Fund’s industry classifications refer to any one or more of the industry sub-classifications used by one or more widely recognized market indexes or ratings group indexes, and/or as defined by Fund management. This definition may not apply for purposes of this report, which may combine industry sub-classifications into sectors for reporting ease.

(1) All percentages shown in the Portfolio of Investments are based on net assets.

(2) For financial reporting purposes, the ratings disclosed are the highest of Standard & Poor’s Group (“Standard & Poor’s”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch, Inc. (“Fitch”) rating. This treatment of split-rated securities may differ from that used for other purposes, such as for Fund investment policies. Ratings below BBB by Standard & Poor’s, Baa by Moody’s or BBB by Fitch are considered to be below investment grade. Holdings designated N/R are not rated by any of these national rating agencies.

(3) Senior loans generally pay interest at rates which are periodically adjusted by reference to a base short-term, floating lending rate plus an assigned fixed rate. These floating lending rates are generally (i) the lending rate referenced by the London Inter-Bank Offered Rate (“LIBOR”), or (ii) the prime rate offered by one or more major United States banks. Senior loans may be considered restricted in that the Fund ordinarily is contractually obligated to receive approval from the agent bank and/or borrower prior to the disposition of a senior Loan. The rate shown is the coupon as of the end of the reporting period.

(4) Senior loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentives for a borrower to prepay, prepayments of senior loans may occur. As a result, the actual remaining maturity of senior loans held may be substantially less than the stated maturities shown.

PIK All or portion of this security is payment-in-kind.

144A Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.

Notes to

Financial Statements(Unaudited)

1. General Information and Significant Accounting Policies

General Information

Trust and Fund Information

The Nuveen Investment Trust III (the “Trust”), is an open-end management investment company registered under the Investment Company Act of 1940, as amended. The Trust is comprised of Nuveen Symphony Credit Opportunities Fund (“Symphony Credit Opportunities”), Nuveen Symphony Floating Rate Income Fund (“Symphony Floating Rate Income”) and Nuveen Symphony High Yield Bond Fund (“Symphony High Yield Bond”) (each a “Fund” and collectively, the “Funds”), as diversified funds, among others. The Trust was organized as a Massachusetts business trust on August 20, 1998.

The end of the reporting period for the Funds is March 31, 2017, and the period covered by these Notes to Financial Statements is the six months ended March 31, 2017 (the “current fiscal period”).

Investment Adviser

The Funds’ investment adviser is Nuveen Fund Advisors, LLC (the “Adviser”), a subsidiary of Nuveen, LLC (“Nuveen”). Nuveen is the investment management arm of Teachers Insurance and Annuity Association of America (TIAA). The Adviser has overall responsibility for management of the Funds, oversees the management of the Funds’ portfolios, manages the Funds’ business affairs and provides certain clerical, bookkeeping and other administrative services, and, if necessary, asset allocation decisions. The Adviser has entered into sub-advisory agreements with Symphony Asset Management LLC (“Symphony”), an affiliate of Nuveen, under which the Symphony manages the investment portfolios of the Funds.

Investment Objectives

The investment objective of Symphony Credit Opportunities and Symphony High Yield Bond is to seek current income and capital appreciation. Symphony Floating Rate Income’s investment objective is to seek a high level of current income and the secondary investment objective of the Fund is to seek capital appreciation.

The Funds’ most recent prospectus provides further descriptions of each Fund’s investment objective, principal investment strategies and principal risks.

Significant Accounting Policies

Each Fund is an investment company and follows 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 followed by the Funds in the preparation of their financial statements in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”).

Investment Transactions

Investment transactions are recorded on a trade date basis. Trade date for senior and subordinated loans purchased in the “primary market” is considered the date on which the loan allocations are determined. Trade date for senior and subordinated loans purchased in the “secondary market” is the date on which the transaction is entered into. Realized gains and losses from investment transactions are determined on the specific identification method, which is the same basis used for federal income tax purposes. Investments purchased on a when-issued/delayed delivery basis may have extended settlement periods. Any investments so purchased are subject to market fluctuation during this period. The Funds have earmarked securities in their portfolios with a current value at least equal to the amount of the when-issued/delayed delivery purchase commitments.

As of the end of the reporting period, the Funds’ outstanding when-issued/delayed delivery purchase commitments were as follows:

	Symphony Credit Opportunities		Symphony Floating Rate Income		Symphony High Yield Bond
Outstanding when-issued/delayed delivery purchase commitments	$	3,615,000	$	150,876,388	$	—

Investment Income

Investment income, which reflects the amortization of premiums and accretion of discounts for financial reporting purposes, is recorded on an accrual basis. Investment income also reflects fee income, if any. Fee income consists primarily of amendment fees. Amendment fees are earned as compensation for evaluating and accepting changes to an original senior loan agreement and are recognized when received.

62 NUVEEN

Professional Fees

Professional fees presented on the Statement of Operations consist of legal fees incurred in the normal course of operations, audit fees, tax consulting fees and, in some cases, workout expenditures. Workout expenditures are incurred in an attempt to protect or enhance an investment or to pursue other claims or legal actions on behalf of Fund shareholders. If a refund is received for workout expenditures paid in a prior reporting period, such amounts will be recognized as “Legal fee refund” on the Statement of Operations.

Dividends and Distributions to Shareholders

Dividends from net investment income are declared daily and distributed to shareholders monthly. Fund shares begin to accrue dividends on the business day after the day when the monies used to purchase Fund shares are collected by the transfer agent.

Net realized capital gains from investment transactions, if any, are declared and distributed to shareholders at least annually. Furthermore, capital gains are distributed only to the extent they exceed available capital loss carryforwards.

Distributions to shareholders are recorded on the ex-dividend date. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.

Share Classes and Sales Charges

Class A Shares are generally sold with an up-front sales charge and incur a 0.25% annual 12b-1 service fee. Class A Share purchases of $1 million or more ($500,000 or more for Symphony Floating Rate Income) are sold at net asset value (“NAV”) without an up-front sales charge but may be subject to a contingent deferred sales charge (“CDSC”) of 1% if redeemed within eighteen months of purchase. Class C Shares are sold without an up-front sales charge but incur a 0.75% annual 12b-1 distribution fee and a 0.25% annual 12b-1 service fee. Class C Shares are subject to a CDSC of 1% if redeemed within twelve months of purchase. Class R6 Shares and Class I Shares are not subject to any sales charge or 12b-1 distribution or service fees.

Multiclass Operations and Allocations

Income and expenses of the Funds that are not directly attributable to a specific class of shares are prorated among the classes based on the relative settled shares of each class. Expenses directly attributable to a class of shares are recorded to the specific class. Currently, the only expenses that are allocated on a class-specific basis are 12b-1 distribution and service fees.

Sub-transfer agent fees, which are recognized as a component of “Shareholder servicing agent fees” on the Statement of Operations, are not charged to Class R6 Shares and are prorated among the other classes based on their settled shares.

Realized and unrealized capital gains and losses of the Funds are prorated among the classes based on the relative net assets of each class.

Compensation

The Trust pays no compensation directly to those of its trustees who are affiliated with the Adviser or to its officers, all of whom receive remuneration for their services to the Trust from the Adviser or its affiliates. The Funds’ Board of Trustees (the “Board”) has adopted a deferred compensation plan for independent trustees that enables trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from certain Nuveen-advised funds. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of select Nuveen-advised funds.

Indemnifications

Under the Trust’s organizational documents, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust. In addition, in the normal course of business, the Trust enters into contracts that provide general indemnifications to other parties. The Trust’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust that have not yet occurred. However, the Trust has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

Netting Agreements

In the ordinary course of business, the Funds may enter into transactions subject to enforceable master repurchase agreements, International Swaps and Derivative Association, Inc. (“ISDA”) master agreements or other similar arrangements (“netting agreements”). Generally, the right to offset in netting agreements allows each Fund to offset certain securities and derivatives with a specific counterparty, when applicable, as well as any collateral received or delivered to that counterparty based on the terms of the agreements. Generally, each Fund manages its cash collateral and securities collateral on a counterparty basis.

The Funds’ investments subject to netting agreements as of the end of the reporting period, if any, are further described in Note 3 – Portfolio Securities and Investments in Derivatives.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the current fiscal period. Actual results may differ from those estimates.

2. Investment Valuation and Fair Value Measurements

The fair valuation input levels as described below are for fair value measurement purposes.

Fair value is defined as the price that would be received upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The following is a summary of the three-tiered hierarchy of valuation input levels.

Level 1 –	Inputs are unadjusted and prices are determined using quoted prices in active markets for identical securities.
Level 2 –	Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).
Level 3 –	Prices are determined using significant unobservable inputs (including management’s assumptions in determining the fair value of investments).

Common stocks and other equity-type securities are valued at the last sales price on the securities exchange on which such securities are primarily traded and are generally classified as Level 1. Securities primarily traded on the NASDAQ National Market (“NASDAQ”) are valued at the NASDAQ Official Closing Price and are generally classified as Level 1. However, securities traded on a securities exchange or NASDAQ for which there were no transactions on a given day or securities not listed on a securities exchange or NASDAQ are valued at the quoted bid price and are generally classified as Level 2.

Prices of fixed-income securities are provided by an independent pricing service (“pricing service”) approved by the Board. The pricing service establishes a security’s fair value using methods that may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. These securities are generally classified as Level 2. In pricing certain securities, particularly less liquid and lower quality securities, the pricing service may consider information about a security, its issuer or market activity provided by the Adviser. These securities are generally classified as Level 2 or Level 3 depending on the observability of the significant inputs.

Like most fixed-income securities, the senior and subordinated loans in which the Funds invest are not listed on an organized exchange. The secondary market of such investments may be less liquid relative to markets for other fixed-income securities. Consequently, the value of senior and subordinated loans, determined as described above, may differ significantly from the value that would have been determined had there been an active market for that senior loan. These securities are generally classified as Level 2.

Repurchase agreements are valued at contract amount plus accrued interest, which approximates market value. These securities are generally classified as Level 2.

Certain securities may not be able to be priced by the pre-established pricing methods as described above. Such securities may be valued by the Board and/or its appointee at fair value. These securities generally include, but are not limited to, restricted securities (securities which may not be publicly sold without registration under the Securities Act of 1933, as amended) for which a pricing service is unable to provide a market price; securities whose trading has been formally suspended; debt securities that have gone into default and for which there is no current market quotation; a security whose market price is not available from a pre-established pricing source; a security with respect to which an event has occurred that is likely to materially affect the value of the security after the market has closed but before the calculation of a Fund’s NAV (as may be the case in non-U.S. markets on which the security is primarily traded) or make it difficult or impossible to obtain a reliable market quotation; and a security whose price, as provided by the pricing service, is not deemed to reflect the security’s fair value. As a general principle, the fair value of a security would appear to be the amount that the owner might reasonably expect to receive for it in a current sale. A variety of factors may be considered in determining the fair value of such securities, which may include consideration of the following: yields or prices of investments of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from security dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor’s credit characteristics considered relevant. These securities are generally classified as Level 2 or Level 3 depending on the observability of the significant inputs. Regardless of the method employed to value a particular security, all valuations are subject to review by the Board and/or its appointee.

*** Value equals zero as of the end of the reporting period.

The Board is responsible for the valuation process and has appointed the oversight of the daily valuation process to the Adviser’s Valuation Committee. The Valuation Committee, pursuant to the valuation policies and procedures adopted by the Board, is responsible for making fair value determinations, evaluating the effectiveness of the Funds’ pricing policies and reporting to the Board. The Valuation Committee is aided in its efforts by the Adviser’s dedicated Securities Valuation Team, which is responsible for administering the daily valuation process and applying fair value methodologies as approved by the Valuation Committee. When determining the reliability of independent pricing services for investments owned by the Funds, the Valuation Committee, among other things, conducts due diligence reviews of the pricing services and monitors the quality of security prices received through various testing reports conducted by the Securities Valuation Team.

The Valuation Committee will consider pricing methodologies it deems relevant and appropriate when making a fair value determination, based on the facts and circumstances specific to the portfolio instrument. Fair value determinations generally will be derived as follows, using public or private market information:

(i) If available, fair value determinations shall be derived by extrapolating from recent transactions or quoted prices for identical or comparable securities.

(ii) If such information is not available, an analytical valuation methodology may be used based on other available information including, but not limited to: analyst appraisals, research reports, corporate action information, issuer financial statements and shelf registration statements. Such analytical valuation methodologies may include, but are not limited to: multiple of earnings, discount from market value of a similar freely-traded security, discounted cash flow analysis, book value or a multiple thereof, risk premium/yield analysis, yield to maturity and/or fundamental investment analysis.

The purchase price of a portfolio instrument will be used to fair value the instrument only if no other valuation methodology is available or deemed appropriate, and it is determined that the purchase price fairly reflects the instrument’s current value.

NUVEEN 65

Notes to Financial Statements(Unaudited) (continued)

For each portfolio security that has been fair valued pursuant to the policies adopted by the Board, the fair value price is compared against the last available and next available market quotations. The Valuation Committee reviews the results of such testing and fair valuation occurrences are reported to the Board.

3. Portfolio Securities and Investments in Derivatives

Portfolio Securities

Repurchase Agreements

In connection with transactions in repurchase agreements, it is each Fund’s policy that its custodian take possession of the underlying collateral securities, the fair value of which exceeds the principal amount of the repurchase transaction, including accrued interest, at all times. If the counterparty defaults, and the fair value of the collateral declines, realization of the collateral may be delayed or limited.

The following table presents the repurchase agreements for the Funds that are subject to netting agreements as of the end of the reporting period, and the collateral delivered related to those repurchase agreements.

Fund	Counterparty	Short-Term Investments, at Value		Collateral Pledged (From) Counterparty*			Net Exposure
Symphony Credit Opportunities	Fixed Income Clearing Corporation	$	15,809,337	$	(15,809,337	)	$	—
Symphony Floating Rate Income	Fixed Income Clearing Corporation		214,291,863		(214,291,863	)		—
Symphony High Yield Bond	Fixed Income Clearing Corporation		198,991		(198,991	)		—

* As of the end of the reporting period, the value of the collateral pledged from the counterparty exceeded the value of the repurchase agreements. Refer to the Fund’s Portfolio of Investments for details on the repurchase agreements.

Zero Coupon Securities

A zero coupon security does not pay a regular interest coupon to its holders during the life of the security. Income to the holder of the security comes from accretion of the difference between the original purchase price of the security at issuance and the par value of the security at maturity and is effectively paid at maturity. The market prices of zero coupon securities generally are more volatile than the market prices of securities that pay interest periodically.

Investments in Derivatives

Each Fund is authorized to invest in certain derivative instruments. The Funds record derivative instruments at fair value, with changes in fair value recognized on the Statement of Operations, when applicable. Even though the Funds’ investments in derivatives may represent economic hedges, they are not considered to be hedge transactions for financial reporting purposes.

Although the Funds are authorized to invest in derivative instruments, and may do so in the future, they did not make any such investments during the current fiscal period.

Market and Counterparty Credit Risk

In the normal course of business each Fund may invest in financial instruments and enter into financial transactions where risk of potential loss exists due to changes in the market (market risk) or failure of the other party to the transaction to perform (counterparty credit risk). The potential loss could exceed the value of the financial assets recorded on the financial statements. Financial assets, which potentially expose each Fund to counterparty credit risk, consist principally of cash due from counterparties on forward, option and swap transactions, when applicable. The extent of each Fund’s exposure to counterparty credit risk in respect to these financial assets approximates their carrying value as recorded on the Statement of Assets and Liabilities.

Each Fund helps manage counterparty credit risk by entering into agreements only with counterparties the Adviser believes have the financial resources to honor their obligations and by having the Adviser monitor the financial stability of the counterparties. Additionally, counterparties may be required to pledge collateral daily (based on the daily valuation of the financial asset) on behalf of each Fund with a value approximately equal to the amount of any unrealized gain above a pre-determined threshold. Reciprocally, when each Fund has an unrealized loss, the Funds have instructed the custodian to pledge assets of the Funds as collateral with a value approximately equal to the amount of the unrealized loss above a pre-determined threshold. Collateral pledges are monitored and subsequently adjusted if and when the valuations fluctuate, either up or down, by at least the pre-determined threshold amount.

Sales and maturities		131,886,177		279,728,902		4,868,849

6. Income Tax Information

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to distribute substantially all of its net investment income and net capital gains to shareholders and to otherwise comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. Therefore, no federal income tax provision is required.

For all open tax years and all major taxing jurisdictions, management of the Funds has concluded that there are no significant uncertain tax positions that would require recognition in the financial statements. Open tax years are those that are open for examination by taxing authorities (i.e., generally the last four tax year ends and the interim tax period since then). Furthermore, management of the Funds is also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

The following information is presented on an income tax basis. Differences between amounts for financial statement and federal income tax purposes are primarily due to timing differences in recognizing certain gains and losses on investment transactions. To the extent that differences arise that are permanent in nature, such amounts are reclassified within the capital accounts as detailed below. Temporary differences do not require reclassification. Temporary and permanent differences do not impact the NAVs of the Funds.

As of March 31, 2017, the cost and unrealized appreciation (depreciation) of investments, as determined on a federal income tax basis, were as follows:

	Symphony Credit Opportunities			Symphony Floating Rate Income			Symphony High Yield Bond
Cost of investments	$	667,188,686		$	1,726,707,759		$	11,896,762
Gross unrealized:
Appreciation	$	18,415,387		$	20,562,542		$	447,527
Depreciation		(71,888,950	)		(47,182,553	)		(980,130	)
Net unrealized appreciation (depreciation) of investments	$	(53,473,563	)	$	(26,620,011	)	$	(532,603	)

Permanent differences, primarily due to federal taxes paid, bond premium amortization adjustments and treatment of notional principal contracts resulted in reclassifications among the Funds’ components of net assets as of September 30, 2016, the Funds’ last tax year end, as follows:

	Symphony Credit Opportunities			Symphony Floating Rate Income			Symphony High Yield Bond
Capital paid-in	$	(6,859	)	$	(12,293	)	$	—
Undistributed (Over-distribution of) net investment income		859,330			1,595,554			10,123
Accumulated net realized gain (loss)		(852,471	)		(1,583,261	)		(10,123	)

The tax components of undistributed net ordinary income and net long-term capital gains as of September 30, 2016, the Funds’ last tax year end, were as follows:

	Symphony Credit Opportunities		Symphony Floating Rate Income		Symphony High Yield Bond
Undistributed net ordinary income1,2	$	8,615,486	$	8,383,137	$	8,669
Undistributed net long-term capital gains		—		—		—

²  Net ordinary income consists of net taxable income derived from dividends, interest, and net short-term capital gains, if any.

The tax character of distributions paid during the Funds’ last tax year ended September 30, 2016, was designated for purposes of the dividends paid deduction as follows:

	Symphony Credit Opportunities		Symphony Floating Rate Income		Symphony High Yield Bond

7. Management Fees and Other Transactions with Affiliates

Management Fees

Each Fund’s management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. Symphony is compensated for its services to the Funds from the management fees paid to the Adviser.

Each Fund’s management fee consists of two components – a fund-level fee, based only on the amount of assets within each individual Fund, and a complex-level fee, based on the aggregate amount of all eligible fund assets managed by the Adviser. This pricing structure enables each Fund’s shareholders to benefit from growth in the assets within their respective Fund as well as from growth in the amount of complex-wide assets managed by the Adviser.

The annual Fund-level fee, payable monthly, for each Fund is calculated according to the following schedule:

Average Daily Net Assets	Symphony Credit Opportunities			Symphony Floating Rate Income			Symphony High Yield Bond
For the first $125 million		0.4500	%		0.4500	%		0.4500	%
For the next $125 million		0.4375			0.4375			0.4375
For the next $250 million		0.4250			0.4250			0.4250
For the next $500 million		0.4125			0.4125			0.4125
For the next $1 billion		0.4000			0.4000			0.4000
For net assets over $2 billion		0.3750			0.3750			0.3750

Notes to Financial Statements (Unaudited) (continued)

The annual complex-level fee, payable monthly, for each Fund is calculated according to the following schedule:

Complex-Level Asset Breakpoint Level*	Effective Rate at Breakpoint Level
$55 billion		0.2000	%
$56 billion		0.1996
$57 billion		0.1989
$60 billion		0.1961
$63 billion		0.1931
$66 billion		0.1900
$71 billion		0.1851
$76 billion		0.1806
$80 billion		0.1773
$91 billion		0.1691
$125 billion		0.1599
$200 billion		0.1505
$250 billion		0.1469
$300 billion		0.1445

* The complex-level fee is calculated based upon the aggregate daily “eligible assets” of all Nuveen funds. Eligible assets do not include assets attributable to investments in other Nuveen funds or assets in excess of a determined amount (originally $2 billion) added to the Nuveen fund complex in connection with the Adviser’s assumption of the management of the former First American Funds effective January 1, 2011. Eligible assets include closed-end fund assets managed by the Adviser that are attributable to certain types of leverage. For these purposes, leverage includes the closed-end funds’ use of preferred stock and borrowings and certain investments in the residual interest certificates (also called inverse floating rate securities) in tender option bond (TOB) trusts, including the portion of assets held by a TOB trust that has been effectively financed by the trust’s issuance of floating rate securities, subject to an agreement by the Adviser as to certain funds to limit the amount of such assets for determining eligible assets in certain circumstances. As of March 31, 2017, the complex-level fee for each Fund was 0.1613%.

The Adviser has agreed to waive fees and/or reimburse expenses (“Expense Cap”) so that total annual Fund operating expenses (excluding 12b-1 distribution and/or service fees, interest expenses, taxes, acquired fund fees and expenses, fees incurred in acquiring and disposing of portfolio securities and extraordinary expenses) do not exceed the average daily net assets of any class of Fund shares in the amounts and for the time periods stated in the following table. However, because Class R6 shares are not subject to sub-transfer agent and similar fees, the total annual fund operating expense for the Class R6 shares will be less than the expense limitation. The expense limitation expiring January 31, 2018 may be terminated or modified prior to that date only with the approval of the Board. The expense limitation in effect thereafter may be terminated or modified only with the approval of shareholders of the Funds.

Fund	Temporary Expense Cap			Temporary Expense Cap Expiration Date	Permanent Expense Cap
Symphony Credit Opportunities		0.79	%	January 31, 2018		1.35	%
Symphony Floating Rate Income		0.85		January 31, 2018		1.10
Symphony High Yield Bond		0.79		January 31, 2018		N/A

Other Transactions with Affiliates

During the current fiscal period, Nuveen Securities, LLC (the “Distributor”), a wholly-owned subsidiary of Nuveen, collected sales charges on purchases of Class A Shares, the majority of which were paid out as concessions to financial intermediaries as follows:

	Symphony Credit Opportunities		Symphony Floating Rate Income		Symphony High Yield Bond
Sales charges collected	$	83,473	$	660,141	$	3,063
Paid to financial intermediaries		7 4,638		611,084		2,788

The Distributor also received 12b-1 service fees on Class A Shares, substantially all of which were paid to compensate financial intermediaries for providing services to shareholders relating to their investments.

During the current fiscal period, the Distributor compensated financial intermediaries directly with commission advances at the time of purchase as follows:

	Symphony Credit Opportunities		Symphony Floating Rate Income		Symphony High Yield Bond
Commission advances	$	55,488	$	675,453	$	1,619

To compensate for commissions advanced to financial intermediaries all 12b-1 service and distribution fees collected on Class C Shares during the first year following a purchase are retained by the Distributor. During the current fiscal period, the Distributor retained such 12b-1 fees as follows:

	Symphony Credit Opportunities		Symphony Floating Rate Income		Symphony High Yield Bond
12b-1 fees retained	$	56,994	$	134,029	$	1,392

70 NUVEEN

The remaining 12b-1 fees charged to the Funds were paid to compensate financial intermediaries for providing services to shareholders relating to their investments.

The Distributor also collected and retained CDSC on share redemptions during the current fiscal period, as follows:

	Symphony Credit Opportunities		Symphony Floating Rate Income		Symphony High Yield Bond
CDSC retained	$	10,412		—		—

As of the end of the reporting period, Nuveen owned shares of the following Funds as follows:

	Symphony Floating Rate Income		Symphony High Yield Bond
Class A Shares		—		2,500
Class C Shares		—		2,500
Class R6 Shares		1,227		1,588
Class I Shares		—		473,594

8. Senior Loan Commitments

Unfunded Commitments

Pursuant to the terms of certain of the variable rate senior loan agreements, the Funds may have unfunded senior loan commitments. Each Fund will maintain with its custodian, cash, liquid securities and/or liquid senior loans having an aggregate value at least equal to the amount of unfunded senior loan commitments. As of the end of the reporting period, the Funds had no such unfunded senior loan commitments.

Participation Commitments

With respect to the senior loans held in each Fund’s portfolio, the Funds may: 1) invest in assignments; 2) act as a participant in primary lending syndicates; or 3) invest in participations. If a Fund purchases a participation of a senior loan interest, the Fund would typically enter into a contractual agreement with the lender or other third party selling the participation, rather than directly with the borrower. As such, the Fund not only assumes the credit risk of the borrower, but also that of the selling participant or other persons interpositioned between the Fund and the borrower. As of the end of the reporting period, the Funds had no such outstanding participation commitments.

9. Borrowing Arrangements

Uncommitted Line of Credit

During the current fiscal period, the Funds participated in an unsecured bank line of credit (“Unsecured Credit Line”) under which outstanding balances would bear interest at a variable rate. Although the Funds participated in the Unsecured Credit Line, they did not have any outstanding balances during the current fiscal period.

$2.5 Billion Committed Line of Credit

The Funds, along with certain other funds managed by the Adviser (“Participating Funds”), have established a 364-day, approximately $2.5 billion standby credit facility with a group of lenders, under which the Participating Funds may borrow for various purposes other than leveraging for investment purposes. A large portion of this facility’s capacity (and its associated costs as described below) is currently dedicated for use by a small number of Participating Funds, which includes the Funds. The remaining capacity under the facility (and the corresponding portion of the facility’s annual costs) is separately dedicated to most of the other open-end funds in the Nuveen fund family along with a number of Nuveen closed-end funds. The credit facility expires in July 2017 unless extended or renewed.

The credit facility has the following terms: a fee of 0.15% per annum on unused commitment amounts, and interest at a rate equal to the higher of (a) one-month LIBOR (London Inter-Bank Offered Rate) plus 1.25% per annum or (b) the Fed Funds rate plus 1.25% per annum on amounts borrowed. Participating Funds paid administration, legal and arrangement fees, which are recognized as a component of “Other expenses” on the Statement of Operations, and along with commitment fees, have been allocated among such Participating Funds based upon the relative proportions of the facility’s aggregate capacity reserved for them and other factors deemed relevant by the Adviser and the Board of each Participating Fund.

$96.7 Million Committed Line of Credit

On October 14, 2016, Symphony Credit Opportunities and Symphony Floating Rate Income, along with certain of the Participating Funds (the “Subset of Participating Funds”), have established a 364-day, $96,687,000 standby credit facility with a lender, under which the Subset of Participating Funds may borrow for various purposes other than leveraging for investment purposes. This standby credit facility is in addition to the $2.5 billion standby credit facility. The Subset of Participating Funds may only borrow from either the $96,687,000 standby credit facility or the $2.5 billion standby credit facility at any one time. This standby credit facility expires in October 2017 unless extended or renewed.

NUVEEN 71

Notes to Financial Statements (Unaudited) (continued)

This standby credit facility has the following terms: a fee of 0.15% per annum on unused commitment amounts, and interest at a rate equal to the higher of (a) one-month LIBOR (London Inter-Bank Offered Rate) plus 1.25% per annum or (b) the Fed Funds rate plus 1.25% per annum on amounts borrowed. Participating Funds will pay administration, legal and arrangement fees, which will be recognized as a component of “Other expenses” on the Statement of Operations, and along with commitment fees, will be allocated among such Subset of Participating Funds based upon the relative proportions of the facility’s aggregate capacity reserved for them and other factors deemed relevant by the Adviser and the Board of each Subset of Participating Fund.

During the current fiscal period, none of the Funds utilized either of these facilities.

10. New Accounting Pronouncements

Amendments to Regulation S-X

In October 2016, the SEC adopted new rules and amended existing rules (together, the “final rules”) intended to modernize the reporting and disclosure of information by registered investment companies. In part, the final rules amend Regulation S-X and require standardized, enhanced disclosure about derivatives in investment company financial statements, as well as other amendments. The compliance date of the amendments to Regulation S-X is August 1, 2017. Management is still evaluating the impact of the final rules, if any.

Accounting Standards Update 2017-08 (“ASU 2017-08”) Premium Amortization on Purchased Callable Debt Securities

During March 2017, the Financial Accounting Standards Board (“FASB”) issued ASU 2017-08, which shortens the premium amortization period for purchased non-contingently callable debt securities. ASU 2017-08 specifies that the premium amortization period ends at the earliest call date, for purchased non-contingently callable debt securities. ASU 2017-08 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Management is currently evaluating the implications of ASU 2017-08, if any.

Glossary of Terms

Used in this Report

Average Annual Total Return: This is a commonly used method to express an investment’s performance over a particular, usually multi-year time period. It expresses the return that would have been necessary each year to equal the investment’s actual cumulative performance (including change in NAV or offer price and reinvested dividends and capital gains distributions, if any) over the time period being considered.

BofA/Merrill Lynch U.S. High Yield Master II Index: Tracks the performance of U.S. Dollar-denominated below investment grade corporate debt publicly issued in the U.S. domestic market. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges and management fees.

Beta: A measure of the volatility of a portfolio relative to the overall market. A beta less than 1.0 indicates lower risk than the market; a beta greater than 1.0 indicates higher risk than the market.

Credit Suisse Leveraged Loan Index: A representative, unmanaged index of tradeable, senior, U.S. dollar-denominated leveraged loans. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.

Custom Benchmark Index: An index comprised 60% of the BofA/Merrill Lynch U.S. High Yield Master II Index and 40% Credit Suisse Leveraged Loan Index. The BofA/Merrill Lynch U.S. High Yield Master II Index tracks the performance of U.S. Dollar-denominated below investment grade corporate debt publicly issued in the U.S. domestic market. The Credit Suisse Leveraged Loan Index is a representative, unmanaged index of tradeable, senior, U.S. dollar-denominated leveraged loans. Index returns assume reinvestment of distributions, but do not reflect any applicable sales charges or management fees.

Lipper High Yield Funds Classification Average: Represents the average annualized total return for all reporting funds in the Lipper High Yield Funds Classification. Lipper returns account for the effects of management fees and assume reinvestment of distributions, but do not reflect any applicable sales charges.

Lipper Loan Participation Funds Classification Average: Represents the average annualized total return for all reporting funds in the Lipper Loan Participation Funds Classification. Lipper returns account for the effects of management fees and assume reinvestment of distributions, but do not reflect any applicable sales charges.

Net Asset Value (NAV) Per Share: A fund’s Net Assets is equal to its total assets (securities, cash and accrued earnings) less its total liabilities. For funds with multiple classes, Net Assets are determined separately for each share class. NAV per share is equal to the fund’s (or share class’) Net Assets divided by its number of shares outstanding.

Zero Coupon Bond: A zero coupon bond does not pay a regular interest coupon to its holders during the life of the bond. Income to the holder of the bond comes from accretion of the difference between the original purchase price of the bond at issuance and the par value of the bond at maturity and is effectively paid at maturity. The market prices of zero coupon bonds generally are more volatile than the market prices of bonds that pay interest periodically.
