(1) The Fund's Advisor, distributor and shareholder services provider have agreed to waive their fees and/or reimburse expenses so that the total annual fund operating expenses paid by the Fund's Class A
Shares and Class I Shares will not exceed 0.81% and 0.56%, respectively *,* not including the effects of acquired fund fees and expenses, taxes, extraordinary expenses, commissions and interest. This waiver may be amended or withdrawn after
August 31, 2026, or with the agreement of the Fund's Board of Trustees.

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's Class A Shares, and Class I Shares 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 that the Fund's operating expenses remain the same and that the fee waivers/expense reimbursements remain in place for the contractual period. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

*WILMINGTON NEW YORK MUNICIPAL BOND FUND* 

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. During the most recent fiscal year, the Fund's portfolio turnover rate was 27% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund seeks to achieve its investment goal, under normal circumstances, by investing its net assets so that at least 80% of the income it distributes will be exempt from federal regular income tax and personal income tax imposed by the State of New York and New York municipalities. However, the income on these securities may be subject to the federal alternative minimum tax ("AMT"). The Fund generally invests in investment grade municipal securities. The Fund seeks to maintain a weighted average maturity of three to ten years. However, the Fund has no maturity restrictions on individual issues, and the weighted average maturity of the Fund's portfolio will vary depending on market conditions.

In selecting securities, the Fund's investment advisor focuses on credit analysis, the relative values of different sectors of the market, geographic diversity and securities with different and potentially advantageous structures. The investment advisor seeks to construct a portfolio with substantially the same interest rate exposure as the Standard & Poor's Investment Grade Intermediate Municipal Bond Index, and does not select securities based on forecasts of interest rates.

Principal Risks of Investing in the Fund

All mutual funds take investment risks. Therefore, it is possible to lose money by investing in the Fund. The primary factors that may reduce the Fund's returns include:

• **Alternative Minimum Tax Risk**. Although the interest received from municipal securities generally is exempt from federal income tax, the Fund may invest a portion of its total assets in municipal securities
subject to the federal alternative minimum tax. Accordingly, investment in the Fund could cause noncorporate shareholders to be subject to (or result in an increased liability under) the federal alternative minimum tax.

• **Call Risk**. Issuers of callable securities may redeem the securities prior to maturity at a price below their current market value.

• **Changing Fixed Income Market Conditions Risk**. Interest rates have changed due to changes in Federal Reserve Bank (FRB) monetary policy actions, as well as the monetary policy responses of other central banks

around the world. In addition, decreases in fixed income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed income markets. As a result, the value of the Fund's investments and share price may decline. Changes in central bank policies could also result in higher than normal shareholder redemptions, which could potentially increase portfolio turnover and the Fund's transaction costs. <br>

• **Credit Risk**. There is a possibility that issuers of securities in which the Fund invests may default in the payment of interest or principal on the securities when due, which would cause the Fund to lose money.

• **Interest Rate Risk**. The risk posed by the fact that prices of fixed income securities rise and fall inversely in response to interest rates changes. For instance, a rise in interest rate causes a fall in the
value of a fixed income securities. In addition, this risk increases with the length of the maturity of the fixed income security. Accordingly, the yield earned by a Fund will vary with changes in interest rates. Also, when interest rates fall, the
price of mortgage-backed securities may not rise to as great an extent as that of other fixed income securities. Duration is a measure of the expected life of a debt security that is used to determine the sensitivity of the security's price to
changes in interest rates. Generally, the longer the Fund's duration, the more sensitive the Fund will be to changes in interest rates.

• **Liquidity Risk**. The risk that certain securities may be difficult or impossible for a Fund to sell or dispose of at the price at which the Fund has valued the security.

• **Market Risk**. There is a risk that the value of the Fund's investments may decrease in response to expected, real or perceived economic, political or financial events in the U.S. or global markets. The
frequency and magnitude of such changes in value cannot be predicted. Certain securities and other investments held by the Fund may experience increased volatility, illiquidity, or other potentially adverse effects in response to changing market
conditions, inflation, changes in interest rates, trade disputes, changes in trade regulation or economic sanctions, elevated levels of government debt, internal unrest and discord, lack of liquidity in the bond or equity markets, volatility in the
equity markets, market disruptions caused by local or regional events such as war, acts of terrorism, the spread of infectious illness (including epidemics and pandemics) or other public health issues, recessions or other events or adverse investor
sentiment or other political, regulatory, economic and social developments, and developments that impact specific economic sectors, industries or segments of the market.

• **Municipal Securities Risk**. The Fund will likely be impacted by events tied to the overall municipal
securities markets. Those markets can be volatile and significantly affected by unfavorable legislative or political

---

|:---|:---|
| ***2*** | *August 31, 2025 / SUMMARY PROSPECTUS* |

*WILMINGTON NEW YORK MUNICIPAL BOND FUND* 

developments and adverse changes in the financial conditions of municipal securities issuers and the economy. Further, a fund that invests in the securities of a particular bond market sector (e.g., healthcare, housing or one political subdivision) is subject to the risk that adverse circumstances will have a greater impact on the fund than a fund that does not make such sector investments. It is possible that economic, business or political developments or other changes affecting one security in the sector will affect other securities in that sector in the same manner.

• **New York Investment Risk**. The Fund will be more susceptible to any economic, business, political or other developments which generally affect securities issued by New York issuers. The economy of New York state
is large and diverse, from agriculture, manufacturing and high technology in upstate counties to advertising, finance and banking in New York City. Any major changes to the financial conditions of New York City, however, would ultimately have an
effect on the state.

• **Tax Risk**. Failure of a municipal security to meet certain legal requirements may cause the interest received and distributed by the Fund to shareholders to be taxable, which could result in a decline in the
security's, and therefore the Fund's, value.

As with any mutual fund investment, loss of money is a risk of investing. An investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The bar chart and table immediately following show the variability of the Fund's returns and are meant to provide some indication of the risks of investing in the Fund by showing changes in the Fund's performance from year to year, with respect to its Class I Shares, and by showing how the Fund's average annual total returns for 1, 5 and 10 years compare with those of a broad measure of market performance. The table also shows the Standard & Poor's Intermediate Municipal Bond Index and the Standard & Poor's Intermediate Term New York AMT-Free Municipal Bond Index, which are additional indices with characteristics relevant to the Fund. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at www.wilmingtonfunds.com.
