Example

This 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 redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and reflects the applicable expense waivers and reimbursements for the 2-year contractual period and the total operating expenses without waivers for years 3 through 10. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Class	A		Inst.		R6
1 year		$353		$65		$62
3 years		$531		$205		$195
5 years		$735		$357		$340
10 years		$1,323		$798		$762

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 the annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Predecessor Fund’s (defined below) portfolio turnover rate was 88% of the average value of its portfolio.

What are the Fund’s principal investment strategies?

Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in securities the income from which is exempt from federal income tax, including the federal alternative minimum tax. This is a fundamental investment policy that may not be changed without prior shareholder approval (80% policy). However, the Fund typically attempts to invest all of its assets in securities that pay interest that is exempt from federal income tax, but may invest up to 20% of its net assets in securities that pay interest that is subject to the federal alternative minimum tax. The Fund diversifies its assets among municipal bonds and securities of different states, municipalities, and US territories.

The Fund primarily invests in high quality municipal securities that are rated as, or, if unrated, are determined by the Fund’s investment manager, Delaware Management Company (Manager), to be, investment grade at the time of purchase. The Fund may invest in securities insured against default by independent insurance companies and revenue bonds.

To a lesser extent, the Fund may invest in high yield, below investment grade municipal bonds (commonly known as “high yield” or “junk bonds”). High yield bonds include those that are rated below Baa3 by Moody’s Investors Service, Inc. or below BBB- by Standard & Poor’s and unrated bonds that are determined by the Manager to be of equivalent quality. When making investment decisions, the Manager focuses on bonds that it believes can generate attractive and consistent income.

In selecting investments for the Fund, the Manager considers various factors, including: a security’s maturity, coupon, yield, credit quality, call protection and relative value and the outlook for interest rates and

the economy. The Manager may sell a security for various reasons, including to replace it with a security that offers a higher yield or better value, respond to a deterioration in credit quality, or raise cash. The Manager generally considers any capital gains or losses that may be incurred upon the sale of an investment. In addition, the Manager considers the duration of the Fund’s portfolio when deciding whether to buy or sell a security.

The Fund will invest its assets in securities with maturities of various lengths, depending on market conditions, but will typically have a dollar-weighted average effective maturity of between 3 and 10 years.

What are the principal risks of investing in the Fund?

Investing in any mutual fund involves the risk that you may lose part or all of the money you invest. Over time, the value of your investment in the Fund will increase and decrease according to changes in the value of the securities in the Fund’s portfolio. The Fund’s principal risks include:

Market risk — The prices of municipal securities may decline in response to certain events, such as general economic and market conditions, adverse political or regulatory developments, and interest rate fluctuations. Adverse market events may lead to increased redemptions, which could cause the Fund to experience a loss or difficulty in selling securities to meet redemptions.

Municipal securities risk — Investments in municipal securities may be negatively affected by political, legal or judicial developments and by economic conditions that threaten the ability of municipalities to raise taxes or otherwise collect revenue.

Credit risk — An issuer may become unable or unwilling to pay interest or principal when due. The prices of debt securities are affected by the issuer’s credit quality and, for insured securities, the quality of the insurer. A municipal issuer’s ability to pay interest and principal may be adversely affected by factors such as economic, political, regulatory, or legal developments; a credit rating downgrade; or other adverse news. Revenue bonds are subject to the risk that the revenues underpinning the bonds may decline or be insufficient to satisfy the bonds’ obligations.

Call risk — When interest rates fall, a callable bond issuer may “call” or repay the security before its stated maturity, and the Fund’s income may decline if it has to reinvest the proceeds at lower interest rates.

Interest raterisk — In general, when interest rates rise, the market values of municipal securities decline, and when interest rates decline, the market values of municipal securities increase. Securities with longer maturities and durations are generally more sensitive to interest rate changes. The Fund typically purchases securities with longer maturities and durations and, therefore, has a high degree of interest rate risk. If interest rates decline, the Fund’s yield may decline and the rates paid on floating rate and variable rate securities will generally decline.

LIBOR risk — The risk that potential changes related to the use of the London interbank offered rate (LIBOR) could have adverse impacts on financial instruments which reference LIBOR. While some instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate setting methodology, not all instruments have such “fallback provisions” and the effectiveness of replacement rates is uncertain. The potential abandonment of LIBOR could affect the value and liquidity of instruments which reference LIBOR, especially those that do not have fallback provisions.

High yield (junk bond) risk — The risk that high yield securities, commonly known as “junk bonds,” are subject to reduced creditworthiness of issuers, increased risk of default, and a more limited and less liquid secondary market. High yield securities may also be subject to greater price volatility and risk of loss of

income and principal than are higher-rated securities. High yield bonds are sometimes issued by municipalities that have less financial strength and therefore have less ability to make projected debt payments on the bonds.

Active management and selection risk — The risk that the securities selected by a fund’s management will underperform the markets, the relevant indices, or the securities selected by other funds with similar investment objectives and investment strategies. The securities and sectors selected may vary from the securities and sectors included in the relevant index.

Tax risk — The Fund may invest in securities that pay taxable interest and/or pay interest that is subject to the federal alternative minimum tax or effect transactions that produce taxable capital gains. Interest on municipal securities may also become subject to income tax due to an adverse legal change or other events.

Liquidity risk — Certain investments, such as municipal securities and derivatives, may be difficult or impossible to sell at a favorable time or price, when, for example, the Fund requires liquidity to make redemptions. Market developments may cause the Fund’s investments to become less liquid and subject to erratic price movements. High yield securities tend to be less liquid.

The Manager is an indirect wholly owned subsidiary of Macquarie Group Limited (MGL). Other than Macquarie Bank Limited (MBL), a subsidiary of MGL and an affiliate of the Manager, none of the entities noted are authorized deposit-taking institutions for the purposes of the Banking Act 1959 (Commonwealth of Australia). The obligations of these entities do not represent deposits or other liabilities of MBL. MBL does not guarantee or otherwise provide assurance in respect of the obligations of these entities, unless noted otherwise. The Fund is governed by US laws and regulations.

How has Delaware Tax-Exempt Income Fund performed?

The bar chart and table below provide some indication of the risks of investing in the Fund. The Fund has adopted the performance of the First Investors Tax Exempt Income Fund (Predecessor Fund) as the result of a reorganization of the Predecessor Fund into the Fund, which was consummated after the close of business on Oct. 4, 2019 (Reorganization). The Fund had not yet commenced operations prior to the Reorganization. The bar chart shows changes in the performance of the Predecessor Fund from year to year and shows how the Predecessor Fund’s average annual total returns for the 1-, 5-, and 10-year or lifetime periods compare with those of a broad measure of market performance. The Predecessor Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. The returns reflect any expense caps in effect during these periods. The returns would be lower without the expense caps.

The returns shown for periods ending on or prior to Oct. 4, 2019 are those of the Class A, Advisor Class, and Institutional Class shares of the Predecessor Fund. Class A, Advisor Class, and Institutional Class shares of the Predecessor Fund were reorganized into Class A, Institutional Class, and Class R6 shares, respectively, of the Fund after the close of business on Oct. 4, 2019. The returns of Class A, Institutional Class, and Class R6 shares of the Fund will be different from the returns of the corresponding classes of the Predecessor Fund as they have different expenses.

* The Fund changed its primary broad-based securities index to the Bloomberg Barclays 3-15 Year Blend Municipal Bond Index as of Oct. 4, 2019. The Fund had previously changed its primary broad-based securities index to the Bloomberg Barclays 1-15 Year Municipal Index as of Jan. 31, 2019. In each case the Fund elected to use the new index because it more closely reflects the Fund’s investment strategies.

After-tax performance is presented only for Class A shares of the Fund. The after-tax returns for other Fund classes may vary. Actual after-tax returns depend on the investor’s individual tax situation and may differ from the returns shown. After-tax returns are not relevant for shares held in tax-advantaged investment vehicles such as employer-sponsored 401(k) plans and individual retirement accounts (IRAs). The after-tax returns shown are calculated using the highest individual federal marginal income tax rates in effect during the periods presented and do not reflect the impact of state and local taxes.
