Delaware Ivy Balanced Fund

July 29, 2021

(formerly, Ivy Balanced 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 Balanced Fund seeks to provide total return through a combination of capital appreciation and current income.

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 52% of the average value of its portfolio.

What are the Fund's principal investment strategies?

Delaware Ivy Balanced Fund seeks to achieve its objective by investing primarily in a diversified mix of stocks, debt securities and short-term instruments, depending on market conditions. Regarding its equity investments, the Fund invests primarily in medium to large, well-established companies, most of which pay a regular dividend, although it may invest in securities issued by companies of any size. The Fund invests at least 50% of its total assets in equity securities. The equity portion of the Fund typically will include a limited number of stocks (generally 45 to 55), with the objective of providing potential capital appreciation and some dividend income. The Fund may invest in preferred stocks.

In addition, the Fund invests at least 30% of its total assets in debt securities with the objective of providing income and relative stability of capital. The majority of the Fund's debt securities are either US government securities or investment-grade corporate bonds rated BBB- or higher by S&P Global Ratings, a division of S&P Global, Inc. (S&P), or comparably rated by another nationally recognized statistical rating organization (NRSRO) or, if unrated, determined by Delaware Management Company (Manager), the Fund's investment manager, to be of comparable quality. The Fund may invest up to 20% of its total assets in non-investment-grade debt securities. The Fund has no limitations on the range of maturities of the debt securities in which it may invest.

In evaluating investments for the Fund, the Manager focuses on companies with resilient business models characterized by stable growth rates; strong balance sheets; relative strength in earnings; attractive return profiles and valuation; and strong free cash flow generation. In so doing, the Manager evaluates a company's management team, its financial position, its competitive position and the condition of its respective industry in addition to other factors. The Manager utilizes financial statements, independent research by its investment management personnel, third party research, brand studies done by outside parties and other tools and processes to identify what it believes to be attractive investment opportunities with a focus on the trajectory and sustainability of a company's business model. The Manager also focuses on companies that possess a sustainable competitive advantage by evaluating factors such as brand equity/loyalty, proprietary technology, switching costs, access to distribution channels, capital requirements, economies of scale, and barriers to entry. In addition, the Manager's analysis informs its view of an appropriate valuation for each potential investment.

Investment opportunities typically fall into two categories: company-specific ideas which include factors such as a company's competitive positioning, production cycles, cost restructuring or a new management team; and thematic ideas where the Manager considers economic or political forces, interest rate term structure variances, cyclical inflections, changes in consumer behavior or technology shifts. In selecting equity securities for the Fund, the Manager begins its investment process by screening companies based on profitability, and then focuses on capital appreciation and some dividend income and follows a growth at a reasonable price investing strategy. In selecting debt securities for the Fund, the Manager focuses on current income and capital preservation and generally seeks to invest in investment-grade securities.

The Fund may invest up to 25% of its total assets in foreign securities, including equity and fixed-income securities. Additionally, 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 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 analysis as identified above in order to determine if the security is appropriately valued or has met its anticipated price. The Manager also may sell a security if the security ceases to produce income, 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 seek investment advice and recommendations from its affiliates: Macquarie Investment Management Europe Limited (MIMEL), Macquarie Investment Management Austria Kapitalanlage AG (MIMAK), and Macquarie Investment Management Global Limited (MIMGL). The Manager may also permit MIMEL, MIMAK, MIMGL, and Macquarie Funds Management Hong Kong Limited (MFMHKL) (together, the 'Affiliated Sub-Advisors') to execute Fund security trades on behalf of the Manager. The Manager may also permit MIMEL, MIMAK, and MIMGL to exercise investment discretion for securities in certain markets where the Manager believes it will be beneficial to utilize an Affiliated Sub-Advisor's specialized market knowledge, and 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.

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.

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.

Preferred stock risk - The risk that preferred stocks may be subordinated to bonds in terms of rights to their share of the company's assets, may be less liquid than many other securities, and

generally offer no voting rights with respect to the issuer.  Preferred stocks may also be adversely affected by interest rates and may be callable by the issuer.

Growth stock risk -Growth stocks reflect projections of future earnings and revenue. These prices may rise or fall dramatically depending on whether those projections are met. These companies' stock prices may be more volatile, particularly over the short term.

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.

Fixed income risk - The risk that bonds may decrease in value if interest rates increase; anissuer may not be able to make principal and interest payments when due; a bond may be prepaid prior to maturity; and, in the case of high yield bonds ('junk bonds'), such bonds may be subject to an increased risk of default, a more limited secondary market than investment grade bonds, and greater price volatility. Interest rate changes are influenced by a number of factors, such as government policy, monetary policy, inflation expectations, and the supply and demand of bonds. Bonds and other fixed income securities with longer maturities or duration generally are more sensitive to interest rate changes. A fund may be subject to a greater risk of rising interest rates due to the current period of historically low interest rates.

US government securities risk - The risk that certain US government securities, such as securities issued by Fannie Mae, Freddie Mac and the FHLB, are not backed by the full faith and credit of the US government and, instead, may be supported only by the credit of the issuer or by the right of the issuer to borrow from the Treasury.

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.

Interest rate risk - The risk that the prices of bonds and other fixed income securities will increase as interest rates fall and decrease as interest rates rise. Interest rate changes are influenced by a number of factors, such as government policy, monetary policy, inflation expectations, and the supply and demand of bonds. Bonds and other fixed income securities with longer maturities or duration generally are more sensitive to interest rate changes. A fund may be subject to a greater risk of rising interest rates due to the current period of historically low interest rates.

Credit risk - The risk that an issuer of a debt security, including a governmental issuer or an entity that insures a bond, may be unable to make interest payments and/or repay principal in a timely manner.

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.

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.

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 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.

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
