Nuveen Short-Duration High Yield Municipal Bond Fund

Nuveen Short Duration High Yield Municipal Bond Fund

Investment Objective

The investment objective of the Fund is to provide high current income exempt from regular federal income taxes.

Capital appreciation is a secondary objective when consistent with the Fund’s primary objective.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund or in other Nuveen Mutual Funds. More information about these and other discounts, as well as eligibility requirements for each share class, is available from your financial advisor and in “What Share Classes We Offer” on page 18 of the Fund’s prospectus, “How to Reduce Your Sales Charge” on page 19 of the prospectus and “Purchase and Redemption of Fund Shares” on page S-47 of the Fund’s statement of additional information.

Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same, and the contractual fee waivers currently in place are not renewed beyond April 30, 2016. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Redemption

Expense Example Nuveen Short-Duration High Yield Municipal Bond Fund (USD $)	A	C	I
1 Year	335	143	66
3 Years	514	443	208

No Redemption

Expense Example, No Redemption Nuveen Short-Duration High Yield Municipal Bond Fund (USD $)	A	C	I
1 Year	335	143	66
3 Years	514	443	208

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance.

Principal Investment Strategies

Under normal market conditions, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in municipal bonds that pay interest that is exempt from regular federal personal income tax. The Fund may invest without limit in securities that generate income subject to the alternative minimum tax. Under normal market conditions, the Fund will maintain an investment portfolio with a weighted average effective duration of less than 4.5 years.

The Fund invests significantly in lower-quality municipal bonds and may employ effective leverage through investments in inverse floaters. These investment strategies should be considered high risk relative to strategies employed by investment grade municipal bond funds.

The Fund generally invests at least 65% of its net assets in low-to-medium-quality bonds rated BBB/Baa or lower by at least one independent rating agency, or, if unrated, judged by the Fund’s sub-adviser to be of comparable quality, although it may invest less than this amount during abnormal market conditions or periods of large cash inflows or outflows. Below investment grade municipal bonds (those rated BB/Ba or lower) are commonly referred to as “high yield” or “junk” bonds. The Fund may invest up to 10% of its net assets in defaulted municipal bonds (i.e., bonds on which the issuer has not paid principal or interest on time).

The Fund may invest in all types of municipal bonds, including general obligation bonds, revenue bonds and participation interests in municipal leases. The Fund may invest in zero coupon bonds, which are issued at substantial discounts from their value at maturity and pay no cash income to their holders until they mature.

The Fund may invest up to 15% of its net assets in municipal securities whose interest payments vary inversely with changes in short-term tax-exempt interest rates (“inverse floaters”). Inverse floaters are derivative securities that provide leveraged exposure to underlying municipal bonds. The Fund’s investments in inverse floaters are designed to increase the Fund’s income and returns through this leveraged exposure. These investments are speculative, however, and also create the possibility that income and returns will be diminished. The Fund may invest in inverse floaters that create effective leverage of up to 15% of the Fund’s total investment exposure. The Fund will only invest in inverse floating rate securities whose underlying bonds are rated A or higher.

The Fund may utilize the following derivatives: futures contracts; options on futures contracts; swap agreements, including interest rate swaps, total return swaps and credit default swaps, and options on swap agreements. The Fund may use these derivatives in an attempt to manage market risk, credit risk and yield curve risk, to manage the effective maturity or duration of securities in the Fund’s portfolio or for speculative purposes in an effort to increase the Fund’s yield or to enhance returns. The use of a derivative is speculative if the Fund is primarily seeking to enhance returns, rather than offset the risk of other positions.

The Fund’s sub-adviser uses a research-intensive investment process to identify high-yielding municipal bonds that offer attractive value in terms of their current yields, prices, credit quality, liquidity and future prospects. The sub-adviser may choose to sell municipal bonds with deteriorating credit or limited upside potential compared to other available bonds.

Principal Risks

The price and yield of this Fund will change daily, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The principal risks of investing in the Fund include:

Alternative Minimum Tax Risk—The Fund has no limit as to the amount that can be invested in alternative minimum tax bonds. Therefore, all or a portion of the Fund’s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax.

Call Risk—If an issuer calls higher-yielding debt instruments held by the Fund, performance could be adversely impacted.

Credit Risk—Credit risk is the risk that an issuer of a debt security may be unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer’s ability or willingness to make such payments. In addition, parties to other financial contracts with the Fund could default on their obligations. Because the Fund invests at least 65% of its assets in low-to-medium-quality bonds, including high yield securities, the Fund’s credit risks are greater than those of funds that buy only investment grade securities. Also, the Fund’s investments in inverse floaters will increase the Fund’s credit risk.

Defaulted Bond Risk—Defaulted bonds are speculative and involve substantial risks in addition to the risks of investing in high yield securities that have not defaulted. The Fund generally will not receive interest payments on the defaulted bonds and there is a substantial risk that principal will not be repaid. In any reorganization or liquidation proceeding relating to a defaulted bond, the Fund may lose its entire investment.

Derivatives Risk—The use of derivatives involves additional risks, such as liquidity, interest rate, counter party, market, credit and management risks, and transaction costs which could leave the Fund in a worse position than if it had not used these instruments. Derivatives may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives could have a large impact on performance. Recent legislation requires the development of a new regulatory framework for the derivatives market. The impact of the new regulations is still unknown, but has the potential to increase the costs of using derivatives, may limit the availability of some forms of derivatives or the Fund’s ability to use derivatives, and may adversely affect the performance of some derivative instruments used by the Fund as well as the Fund’s ability to pursue its investment objective through the use of such instruments.

High Yield Securities Risk—High yield securities are high risk investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities.

Income Risk—The Fund’s income could decline during periods of falling interest rates. Also, if the Fund invests in inverse floaters, the Fund’s income may decrease if short-term interest rates rise.

Interest Rate Risk—Interest rate risk is the risk that the value of the Fund’s portfolio will decline because of rising interest rates. When interest rates change, the values of longer-duration debt securities usually change more than the values of shorter-duration debt securities.

Inverse Floaters Risk—The use of inverse floaters by the Fund creates effective leverage. Due to the leveraged nature of these investments, they will typically be more volatile and involve greater risk than the fixed rate municipal bonds underlying the inverse floaters. An investment in certain inverse floaters will involve the risk that the Fund could lose more than its original principal investment. Distributions on inverse floaters bear an inverse relationship to short-term municipal bond interest rates. Thus, distributions paid to the Fund on its inverse floaters will be reduced or even eliminated as short-term municipal interest rates rise and will increase when short-term municipal interest rates fall. Inverse floaters generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment.

Liquidity Risk—The secondary market for municipal bonds, and particularly for high-yield municipal bonds, tends to be less well developed and less liquid than many other securities markets. As a result, the Fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on performance. If the Fund needed to sell large blocks of bonds to meet shareholder redemption requests or to raise cash, those sales could further reduce the bonds’ prices. The Fund may invest a significant portion of its assets in unrated bonds. The market for these bonds may be less liquid than the market for rated bonds of comparable quality.

Market Risk—The market values of the Fund’s investments may decline, at times sharply and unpredictably.

Municipal Lease Obligations Risk—Participation interests in municipal leases pose special risks because many leases and contracts contain “non-appropriation” clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for this purpose by the appropriate legislative body.

Political and Economic Risks—The values of municipal securities held by the Fund may be adversely affected by local political and economic conditions and developments. Adverse conditions in an industry significant to a local economy could have a correspondingly adverse effect on the financial condition of local issuers.

Tax Risk—Income from municipal bonds held by the Fund could be declared taxable because of, among other things, unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a bond issuer. In addition, a portion of the Fund’s otherwise exempt-interest dividends may be taxable to those shareholders subject to the federal alternative minimum tax.

Zero Coupon Bonds Risk—Zero coupon bonds do not pay interest on a current basis and may be highly volatile as interest rates rise or fall. In addition, while such bonds generate income for purposes of generally accepted accounting standards, they do not generate cash flow and thus could cause the Fund to be forced to liquidate securities at an inopportune time in order to distribute cash, as required by tax laws.

Fund Performance

Fund performance is not included in this prospectus because the Fund has not been in existence for a full calendar year.

[1] The contingent deferred sales charge on Class C shares applies only to redemptions within 12 months of purchase.

[2] Fee applies to the following types of accounts under $1,000 held directly with the Fund: accounts established pursuant to the Uniform Transfers to Minors Act (UTMA) or Uniform Gifts to Minors Act (UGMA).

[1] Other Expenses are estimated assuming that the Fund's average net assets for its first fiscal year are $50 million.

[2] The Fund's investment adviser has agreed to waive fees and/or reimburse expenses through April 30, 2016 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 0.65% of the average daily net assets of any class of Fund shares. The expense limitation expiring April 30, 2016 may be terminated or modified prior to that date only with the approval of the Board of Trustees of the Fund.
