1 Please see the tooltip on the distribution rate.

If a distribution is estimated to include anything other than net investment income, the Fund provides a Section 19(a) notice of the best estimate of its distribution sources at that time which may be viewed in the Fund’s literature section under 19(a) notices. These estimates may not match the final tax characterization (for the full year's distributions) contained in shareholders' 1099-DIV forms after the end of the year. The distribution rate should not be confused with yield or performance.

Performance data shown represents past performance and does not predict or guarantee 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 assume the reinvestment of distributions, and if shown for a period of less than one year are cumulative. Returns without sales charges would be lower if the sales charges were included. Class I shares have no sales charge and may be purchased by specified classes of investors. For performance current to the most recent month-end, call 800.752.8700 or visit nuveen.com

To view standardized and/or most recent month-end performance, click the fund's ticker symbol.

Overview

An interval fund is a continuously offered closed-end fund that provides periodic liquidity through share repurchases (typically monthly, quarterly, semi-annually or annually). Investors can access less liquid investment strategies in a registered product and enter or exit their investment at net asset value (NAV). An interval fund shares characteristics of an open-end fund, closed-end fund and private fund, for investors with a higher tolerance for risk and illiquidity preference.

Frequently asked questions

1. What are municipal bonds?

Municipal bonds (munis) are debt securities issued by states, cities, counties and other entities to finance public purpose projects and infrastructure such as bridges, schools, roads, hospitals, airports and water systems. Investors in municipal bonds receive regular interest payments and repayment of principal at maturity of the bond. Municipal bonds provide income from interest payments that are usually exempt from federal income tax and, in some cases, state and local taxes.

2. Why do investors choose municipal bonds?
 

Many investors use municipal bonds to generate tax-exempt income while helping to diversify investment portfolios and smooth out overall portfolio volatility1,4. When comparing municipals to other taxable bonds, municipals have had historically lower default rates2.

There is also a segment within the overall municipal bond market for taxable municipal bonds, and these investments are generally used by institutional investors outside the U.S. who are seeking ways to generate yield while diversifying risk3 and maintaining higher quality within their overall portfolio.

Since each investor’s tax situation is different, it is important to consult with a financial and tax professional.

3. How do municipal bonds compare with Treasury bonds? 

Municipal bonds and U.S. Treasury securities are both generally considered high-quality fixed income investments, but they differ in tax treatment, issuer type, yield characteristics, credit characteristics, and sensitivity to interest rates and market conditions. One key difference is that municipal bonds are backed by the issuer’s creditworthiness, while U.S. Treasuries are backed by the full faith and credit of the U.S. government for the timely payment of principal and interest.

4. How do interest rates affect municipal bond prices?

Municipal bond prices generally move inversely to interest rates. As interest rates rise, bond prices fall. Conversely, as interest rates fall, bond prices rise.

5. Are municipal bonds considered safe investments?
 

Municipal bonds have historically experienced relatively low default rates compared with many other fixed income sectors2.  However, no investment is risk-free, and the credit quality of individual issuers should always be evaluated.

6. What is the municipal bond yield curve?

The municipal bond yield curve illustrates the yields, or interest rates, for municipal bonds across a range of maturities, from short-term to long-term. Typically, longer-term bonds will have higher yields than shorter bonds to compensate for added duration risk for longer maturities. Changes in the yield curve may provide insight into investor expectations regarding interest rates, economic growth and inflation.

7. How can municipal bonds help diversify an investment portfolio?

Municipal bonds may help diversify a portfolio by providing income and returns that have historically been less correlated with equities, which can help reduce overall portfolio volatility over time.1,4 During times of market stress, investments may become more closely correlated, and diversification does not assure a profit or protect against loss.

Important information on risk

Investing involves risk; principal loss is possible. All investments carry a certain degree of risk and there is no assurance that an investment will provide positive performance over any period of time. Investing in municipal bonds involves risks such as interest rate risk, credit risk and market risk. The value of the portfolio will fluctuate based on the value of the underlying securities. Bond insurance guarantees only the payment of principal and interest on the bond when due, and not the value of the bonds themselves, which will fluctuate with the bond market and the financial success of the issuer and the insurer. No representation is made as to an insurer’s ability to meet their commitments. This information should not replace an investor’s consultation with a financial professional regarding their tax situation. Nuveen is not a tax professional.

Investors should contact a tax professional regarding the appropriateness of tax-exempt investments in their portfolio. If sold prior to maturity, municipal securities are subject to gain/losses based on the level of interest rates, market conditions and the credit quality of the issuer. Income may be subject to the alternative minimum tax (AMT) and/or state and local taxes, based on the state of residence. Income from municipal bonds held by a portfolio could be declared taxable because of unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer. It is important to review your investment objectives, risk tolerance and liquidity needs before choosing an investment style or manager.
