Delaware Ivy Global Equity Income Fund

July 29, 2021

(formerly, Ivy Global Equity Income Fund)

On April 30, 2021, the funds in this prospectus (Funds) became part of Delaware Funds® by Macquarie and Delaware Management Company became each Fund's investment manager (hereinafter, the Funds and other legacy Ivy Funds are referred to as Transaction Funds to differentiate them from the other Delaware Funds by Macquarie, the non-Transaction Funds).

What is the Fund's investment objective?

Delaware Ivy Global Equity Income Fund seeks to provide total return through a combination of current income and capital appreciation.

What are the Fund's fees and expenses?

Delaware Distributors, L.P. (Distributor), the Fund's distributor and/or Waddell & Reed Services Company, doing business as WI Services Company (WISC), the Fund's transfer agent, have voluntarily agreed to waive all or a portion of its 12b-1 fees and/or shareholder servicing fees to cap the total annual ordinary fund operating expenses (which would exclude interest, taxes, brokerage commissions, acquired fund fees and expenses and extraordinary expenses, if any) in order to allow the Class Y expense rate to float to the Class A expense rate and to allow the Class R6 expense rate to float to the Class I expense rate from July 29, 2021 until such time as the voluntary expense cap is discontinued. This waiver is voluntary and may be modified or discontinued by the Distributor or WISC at any time, and without further notice.

The table below 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 Transaction Funds. More information about these and other discounts is available from your financial intermediary, in the Fund's Prospectus under the section entitled 'About your account,' and in the Fund's statement of additional information (SAI) under the section entitled 'Purchasing Shares.' The Fund's Class B shares are not available for purchase by new or existing investors, but are available for dividend reinvestment and exchanges.

Shareholder fees (fees paid directly from your investment)

Annual fund operating expenses (expenses that you pay each year as a percentage of the value of your investment)

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. In addition, the example shows expenses for Class B shares, assuming those shares were not redeemed 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 1-year contractual period and the total operating expenses without waivers for years 2 through 10. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 Fund's portfolio turnover rate was 39% of the average value of its portfolio.

What are the Fund's principal investment strategies?

Delaware Ivy Global Equity Income Fund seeks to achieve its objective by investing in equity securities that are issued by companies of any size located largely in developed markets around the world, that the Manager believes will be able to generate a reasonable level of current income for investors given current market conditions, and that demonstrate favorable prospects for total return. The Fund focuses on companies that the Manager believes have the ability to maintain and/or grow their dividends while providing capital appreciation over the long-term. The Fund typically holds a limited number of stocks (generally 40 to 55).

Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities. For this purpose, such equity securities consist primarily of dividend-paying common stocks across the globe. Although the Fund invests primarily in large-capitalization companies (typically companies with market capitalizations of at least $10 billion at the time of acquisition), it may invest in companies of any size.

Under normal circumstances, the Fund invests at least 40% (or, if the Manager deems it warranted by market conditions, at least 30%) of its total assets in securities of non-US issuers. The Fund may invest in US and non-US issuers, including issuers located in emerging market countries, and may invest up to 100% of its total assets in foreign securities.

In selecting securities for the Fund, the Manager uses a company-specific stock selection process. The Manager seeks to identify higher-quality companies that it believes are reasonably-valued, have a strong likelihood of maintaining and/or growing their dividend, and have a relatively stable to improving fundamental outlook, relative to market expectations. The Manager considers an analysis of sectors/industries and geographical areas (when relevant) when determining the attractiveness of names and weightings of sectors, and to a lesser degree, countries. The Manager also considers several other factors, including a company's history of fundamentals, ability to sustain its business

model, growth potential, management proficiency and competitive environment. Part of the Manager's process includes an initial screening of the investable universe based on key financial, valuation and technical criteria.

Many of the companies in which the Fund may invest have diverse operations, with products or services in foreign markets. Therefore, the Fund may have indirect exposure to various additional foreign markets through investments in these companies, even if the Fund is not invested directly in such markets.

Generally, in determining whether to sell a security, the Manager uses the same type of analysis that it uses in buying securities of that type. For example, the Manager may sell a security if it believes the security no longer offers attractive current income prospects or significant growth potential, if it believes the management of the company has weakened, and/or there exists political or economic instability in the issuer's country. The Manager also may sell a security to reduce the Fund's holding in that security, to take advantage of what it believes are more attractive investment opportunities or to raise cash.

The Manager may permit its affiliates, Macquarie Investment Management Global Limited (MIMGL) and Macquarie Funds Management Hong Kong Limited, to execute Fund security trades on behalf of the Manager. The Manager may also seek quantitative support from MIMGL.

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. An investment in the Fund may not be appropriate for all investors. The Fund's principal risks include:

Market risk - The risk that all or a majority of the securities in a certain market - such as the stock or bond market - will decline in value because of factors such as adverse political or economic conditions, future expectations, investor confidence, or heavy institutional selling.

Large-capitalization company risk - Large-capitalization companies tend to be less volatile than companies with smaller market capitalizations. This potentially lower risk means that the Fund's share price may not rise as much as the share prices of funds that focus on smaller-capitalization companies.

Foreign risk - The risk that foreign securities (particularly in emerging markets) may be adverselyaffected by political instability, changes in currency exchange rates, inefficient markets and higher transaction costs, foreign economic conditions, the imposition of economic or trade sanctions, or inadequate or different regulatory and accounting standards.

Currency risk - The risk that fluctuations in exchange rates between the US dollar and foreign currencies and between various foreign currencies may cause the value of an investment to decline.

Value stock risk - The risk that the value of a security believed by the Manager to be undervalued may never reach what is believed to be its full value; such security's value may decrease or such security may be appropriately priced. Value stocks are stocks of companies that may have experienced

adverse business or industry developments or may be subject to special risks that have caused the stocks to be out of favor and, in the opinion of the Manager, undervalued.

Small- and mid-market capitalization company risk - The risk that investments in small- and/or medium-sized companies may bemore volatile than those of larger companies because of limited financial resources or dependence on narrow product lines.

Emerging markets risk - The risk associated with international investing will be greater in emerging markets than in more developed foreign markets because, among other things, emerging markets may have less stable political and economic environments. In addition, there often is substantially less publicly available information about issuers and such information tends to be of a lesser quality. Economic markets and structures tend to be less mature and diverse and the securities markets may also be smaller, less liquid, and subject to greater price volatility.

Industry and sector risk - The risk that the value of securities in a particular industry or sector (such as financials) will decline because of changing expectations for the performance of that industry or sector.

Liquidity risk - The possibility that investments cannot be readily sold within seven calendar days at approximately the price at which a fund has valued them.

Limited number of securities risk - The possibility that a single security's increase or decrease invalue may have a greater impact on a fund's value and total return because the fund may hold larger positions in fewer securities than other funds. In addition, a fund that holds a limited number of securities may be more volatile than those funds that hold a greater number of securities.

IBOR risk - The risk that changes related to the use of the London Interbank Offered Rate (LIBOR) or similar interbank offered rates ('IBORs,' such as the Euro Overnight Index Average (EONIA)) could have adverse impacts on financial instruments that reference LIBOR or a similar rate. While some instruments may contemplate a scenario where LIBOR or a similar rate 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 abandonment of LIBOR and similar rates could affect the value and liquidity of instruments that reference such rates, especially those that do not have fallback provisions. The use of alternative reference rate products may impact investment strategy performance.

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.

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 Ivy Global Equity Income Fund performed?

The bar chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund's performance from year to year and by showing how the Fund's average annual total returns for the 1-, 5-year, and lifetime periods compare with those of a broad measure of market performance. On April 30, 2021, the Fund became part of Delaware Funds® by Macquarie and Delaware Management Company became the Fund's investment manager; however, the portfolio managers have not changed. The returns shown from before April 30, 2021 are from the Fund's prior investment manager. The Fund's past performance (before and after taxes) is not necessarily an indication of how it 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. You may obtain the Fund's most recently available month-end performance by calling 888 923-3355 or by visiting our website at ivyinvestments.com.

Calendar year-by-year total return (Class A)

As of June 30, 2021, the Fund's Class A shares had a calendar year-to-date return of 10.58%. During the periods illustrated in this bar chart, Class A's highest quarterly return was 15.43% for the quarter ended Dec. 31, 2020, and its lowest quarterly return was -24.46% for the quarter ended March 31, 2020. The maximum Class A sales charge of 5.75%, which is normally deducted when you purchase shares, is not reflected in the highest/lowest quarterly returns or in the bar chart. If this fee were included, the returns would be less than those shown. The average annual total returns in the table below do include the sales charge.

Average annual total returns for periods ended December 31, 2020

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. Return after taxes on distributions and sale of Fund shares may be better than return before taxes due to an assumed tax benefit from losses on a sale of the Fund's shares at the end of the period.
