Delaware Ivy Global Bond Fund, a series of Ivy Funds

On April 30, 2021, the fund in this prospectus (each, a Fund) became part of Delaware Funds by Macquarie​® and Delaware Management Company became the Fund’s investment manager.

What is the Fund’s investment objective?

Delaware Ivy Global Bond Fund seeks to provide a combination of current income and capital appreciation.

What are the Fund’s fees and expenses?

The table below describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales-charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in Delaware Funds by Macquarie. 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.”

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. 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 50% of the average value of its portfolio.

What are the Fund’s principal investment strategies?

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, including those located in at least three countries including the United States. Non-US issuers are those that are (1) economically tied to a non-US country or countries, or (2) issued or guaranteed by a company domiciled in, or government of, a non-US country. The Fund may invest in debt securities, including secured and unsecured loan assignments, loan participations and other loan instruments (loans), issued by foreign or US companies of any size, including those in emerging markets, as well as in debt securities issued by foreign or US governments. The Fund may invest up to 100% of its total assets in foreign securities and in securities denominated in currencies other than the US dollar. The Fund may invest in securities of any maturity. The Fund will invest at least 65% of its total assets in equity securities of issuers that are organized, have a majority of their assets, or generate the majority of their operating income outside the United States.

The Fund may invest in both investment and non-investment-grade securities. It may invest up to 35% of its total assets in non-investment-grade bonds, commonly called “high-yield” or “junk” bonds, that include bonds rated BB+ or lower 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 the Manager to be of comparable quality. The Fund will invest in non-investment-grade securities only if the Manager deems the risks to be consistent with the Fund’s objectives.

The Manager may consider analysis of environmental, social and governance (ESG) factors in evaluating investments for the Fund. This analysis considers various inputs, including metrics sourced from external parties and ESG research providers; commitments on ESG progress from issuers; specific bond formats (such as green or sustainability-linked bonds); issuer engagement; and other external and proprietary inputs to judge the issuer’s contribution to improvements in ESG practice. The Fund may favor securities of issuers that are judged by the Manager to meet high ESG standards, and may avoid investment in certain industry sectors, or in securities of issuers that are judged to not meet the Manager’s ESG requirements. The Manager relies on a proprietary ESG framework where issuers are assessed on their exposure to, and management of, environmental, social and governance risks. The Manager’s ESG framework relies on its quantitative and qualitative analysis of factors such as industry sector, issuer specific factors such as history and management, and data from multiple sources, including government reports, company filings and external data providers. This framework is subjective in nature and not intended to be an exhaustive list of all possible risks and are provided as an indication of the types of factors being utilized by the Manager.

The Fund may invest in mortgage-backed securities and other asset-backed securities.

The Fund may also use a wide range of derivatives instruments, typically including options, futures contracts, options on futures contracts, forwards, and swaps. The Fund will use derivatives for both hedging and nonhedging purposes. For example, the Fund may invest in: futures and options to manage duration and for defensive purposes, such as to protect gains or hedge against potential losses in the portfolio without actually selling a security, or to stay fully invested; forward foreign currency contracts to manage foreign currency exposure; interest rate swaps to neutralize the impact of interest rate changes; credit default swaps to hedge against a credit event, to gain exposure to certain securities or markets, or to enhance total return; and index swaps to enhance return or to effect diversification. The Fund will not use derivatives for reasons inconsistent with its investment objective.

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.

The Manager may look at a number of factors in selecting securities for the Fund’s portfolio including: identifying fundamental global themes; country analysis (economic, legislative/judicial and demographic trends); credit analysis of the issuer (financial strength, cash flow, balance sheet, capital structure, management, strategy and accounting); the maturity, quality, and denomination (US dollar, euro, yen, other) of the issue; domicile, market share and industry of the issuer; and analysis of the issuer’s profit history through various economic cycles.

Generally, in determining whether to sell a security, the Manager continues to analyze the factors considered for buying the security. The Manager also considers its assumptions regarding a company, an industry, the markets, an individual economy and/or the global economy. The Manager 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 seek investment advice and recommendations from its affiliates: Macquarie Investment Management Austria Kapitalanlage AG (MIMAK), Macquarie Investment Management Europe Limited (MIMEL), and Macquarie Investment Management Global Limited (MIMGL) (together, the

“Affiliated Sub-Advisors”). The Manager may also permit these Affiliated Sub-Advisors to execute Fund security trades on behalf of the Manager and 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.

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:

Capital repatriation risk — The risk that a fund may be unable to repatriate capital from its investments, in whole or in part, which may have an adverse effect on the cash flows and/or performance of the fund. Capital repatriation involves the transfer of corporate money or property from a foreign country back to its home country. The repatriation of capital with regard to investments made in certain securities or countries may be restricted during certain times from the date of such investments or even indefinitely.

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.

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.

Prepayment risk — The risk that the principal on a bond that is held by a fund will be prepaid prior to maturity at a time when interest rates are lower than what that bond was paying. A fund may then have to reinvest that money at a lower interest rate.

Fixed income risk — The risk that bonds may decrease in value if interest rates increase; an issuer 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.

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.

Foreign risk — The risk that foreign securities (particularly in emerging markets) may be adversely affected 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.

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.

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.

Bank loans and other direct indebtedness risk — The risk that the portfolio will not receive payment of principal, interest, and other amounts due in connection with these investments and will depend primarily on the financial condition of the borrower and the lending institution.

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.

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.

Derivatives risk — Derivatives contracts, such as futures, forward foreign currency contracts, options, and swaps, may involve additional expenses (such as the payment of premiums) and are subject to significant loss if a security, index, reference rate, or other asset or market factor to which a derivatives contract is associated, moves in the opposite direction from what the portfolio manager anticipated. When used for hedging, the change in value of the derivatives instrument may also not correlate specifically with the currency, rate, or other risk being hedged, in which case a fund may not realize the intended benefits. Derivatives contracts are also subject to the risk that the counterparty may fail to perform its obligations under the contract due to, among other reasons, financial difficulties (such as a bankruptcy or reorganization).

Mortgage-backed and asset-backed securities risk — The risk that the principal on mortgage-backed or asset-backed securities may be prepaid at any time, which will reduce the yield and market value.

Environmental, social and governance (ESG) investing risk — ESG investing risk is the risk that a fund’s strategy may exclude securities of certain issuers for non-financial reasons and the fund may forgo some market opportunities available to funds that do not integrate ESG factors in investment decisions. In addition, there is a risk that the companies identified by a fund’s ESG factors will not operate as expected when addressing ESG issues or they will not exhibit positive ESG characteristics as intended.

Government and regulatory risk — The risk that governments or regulatory authorities may take actions that could adversely affect various sectors of the securities markets and affect fund performance.

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.

How has Delaware Ivy Global Bond 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-, and 10-year or 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. 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 800 523-1918 or by visiting our website at delawarefunds.com/performance.

Effective November 15, 2021, the Fund’s subadvisers changed to Macquarie Investment Management Austria Kapitalanlage, Macquarie Investment Management Europe Limited, Macquarie Investment Management Global Limited, and the Fund changed its investment strategy. The Fund’s performance prior to November 15, 2021 reflects the Fund’s former strategy; its performance may have differed if the Fund’s current strategy had been in place.

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

As of June 30, 2022, the Fund’s Class A shares had a calendar year-to-date return of -9.60%. During the periods illustrated in this bar chart, Class A’s highest quarterly return was 9.39% for the quarter ended June 30, 2020, and its lowest quarterly return was -6.60% for the quarter ended March 31, 2020. The maximum Class A sales charge of 4.50%, 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, 2021

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.

Ask your salesperson or visit your financial intermediary’s website for more information.

Delaware Ivy High Income Fund, a series of Ivy Funds
 

On April 30, 2021, the fund in this prospectus (each, a Fund) became part of Delaware Funds by Macquarie​® and Delaware Management Company became the Fund’s investment manager.

What is the Fund’s investment objective?

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

What are the Fund’s fees and expenses?

The table below describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales-charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in Delaware Funds by Macquarie. 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.”

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. 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 48% of the average value of its portfolio.

What are the Fund’s principal investment strategies?

Delaware Ivy High Income Fund seeks to achieve its objective by investing primarily in a diversified portfolio of high-yield, high-risk, fixed-income securities, including secured and unsecured loan assignments, loan participations and other loan instruments (loans), of US and foreign issuers, the risks of which are, in the judgment of Delaware Management Company (Manager) consistent with the Fund’s objective. The Fund invests primarily in lower-quality debt securities, which include debt securities rated BB+ or lower 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 the Manager to be of comparable quality. The Fund may invest up to 100% of its total assets in non-investment-grade debt securities, commonly called “high-yield” or “junk” bonds, which include debt securities rated BB+ or lower by S&P, or comparably rated by another NRSRO or, if unrated, determined by the Manager to be of comparable quality. The Fund may invest in fixed-income securities of any maturity.

The Fund may invest up to 100% of its total assets in foreign securities that are denominated in US dollars or foreign currencies. 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.

The Fund may invest in restricted securities.

Although the Manager considers credit ratings in selecting investments for the Fund, the Manager bases its investment decisions for a particular instrument primarily on its own credit analysis and not on a NRSRO’s credit rating. In selecting securities, the Manager may conduct an initial screening of issuers based on characteristics such as yield, performance, maturity and relative value across and within sectors. Following its initial screening, the Manager may look at a number of factors beginning with a primarily bottom-up (researching individual issuers) analysis that includes extensive modeling and talking with a company’s management team, industry consultants and sell-side research to help formulate opinions, and progressing to consideration of the current economic environment, the direction and level of interest rates and inflation, and industry fundamentals and trends in the general economy. Other factors considered include a company’s financial strength, growth of operating cash flows, strength of management, borrowing requirements, improving credit metrics, potential to improve credit standing, responsiveness to changes in interest rates and business conditions, strength of business model, competitive advantage and capital structure and future capital needs. Initial position sizes are determined based on factors that include size of issue, rating, duration, coupon, call-ability, exposure to a specific industry and leverage.

The Manager attempts to optimize the Fund’s risk/reward by investing in the debt portion of the capital structure that the Manager believes to be most attractive, which may include secured and/or unsecured loans, floating rate notes and/or secured and/or unsecured high-yield bonds. For example, if the Manager believes that market conditions are favorable for a particular type of fixed-income instrument, such as high-yield bonds, most or all of the fixed-income instruments in which the Fund invests may be high-yield bonds. Similarly, if the Manager believes that market conditions are favorable for loans, most or all of the fixed-income instruments in which the Fund invests may be loans, including second-lien loans which typically are lower in the capital structure and less liquid than first-lien loans.

Generally, in determining whether to sell a security, the Manager considers the dynamics of an industry and/or company change or anticipated change, a change in strategy by a company, a deterioration of the company’s financial model, credit quality or credit standing, and/or a change in management’s consideration of its creditors. The Manager also may sell a security if, in the Manager’s opinion, the price of the security has risen to fully reflect the company’s improved creditworthiness and other investments with greater potential exist. The Manager also may sell a security to take advantage of what it believes are more attractive investment opportunities, to reduce the Fund’s holding in that security or to raise cash.

The Manager may seek investment advice and recommendations from its affiliates: Macquarie Investment Management Europe Limited, Macquarie Investment Management Austria Kapitalanlage AG, and Macquarie Investment Management Global Limited (together, the “Affiliated Sub-Advisors”). The Manager may also permit these Affiliated Sub-Advisors to execute Fund security trades on behalf of the Manager and 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.

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:

Foreign risk — The risk that foreign securities (particularly in emerging markets) may be adversely affected 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.

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.

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.

Bank loans and other direct indebtedness risk — The risk that the portfolio will not receive payment of principal, interest, and other amounts due in connection with these investments and will depend primarily on the financial condition of the borrower and the lending institution.

Restricted securities risk — The risk that restricted securities are subject to legal or contractual restrictions on resale, and there can be no assurance of a ready market for resale. These securities include private placements or other unregistered securities, such as “Rule 144A Securities”, which are securities that may be sold only to qualified institutional buyers pursuant to the Securities Act of 1933, as amended (1933 Act). Privately placed securities, Rule 144A securities and other restricted securities may have the effect of increasing the level of Fund illiquidity to the extent the Fund finds it difficult to sell these securities when the Manager believes it is desirable to do so, especially under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, and the prices realized could be less than those originally paid, or less than the fair market value. At times, the illiquidity of the market, as well as the lack of publicly available information regarding these securities also may make it difficult to determine the fair market value of such securities for purposes of computing the NAV of the Fund.

Fixed income risk — The risk that bonds may decrease in value if interest rates increase; an issuer 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.

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.

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.

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.

Prepayment risk — The risk that the principal on a bond that is held by a fund will be prepaid prior to maturity at a time when interest rates are lower than what that bond was paying. A fund may then have to reinvest that money at a lower interest rate.

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.

How has Delaware Ivy High 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-, and 10-year or 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. 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 800 523-1918 or by visiting our website at delawarefunds.com/performance.

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

As of June 30, 2022, the Fund’s Class A shares had a calendar year-to-date return of -15.68%. During the periods illustrated in this bar chart, Class A’s highest quarterly return was 8.54% for the quarter ended June 30, 2020, and its lowest quarterly return was -15.83% for the quarter ended March 31, 2020. The maximum Class A sales charge of 4.50%, 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, 2021

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.

Delaware Global Real Estate Fund, a series of Ivy Funds
 

(formerly, Delaware Ivy LaSalle Global Real Estate Fund)

On April 30, 2021, the fund in this prospectus (each, a Fund) became part of Delaware Funds by Macquarie​® and Delaware Management Company became the Fund’s investment manager.

What is the Fund’s investment objective?

Delaware Global Real Estate Fund seeks to provide total return through long-term capital appreciation and current income.

What are the Fund’s fees and expenses?

The table below describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. 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 Delaware Funds by Macquarie. 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.”

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. 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 88% of the average value of its portfolio.

What are the Fund’s principal investment strategies?

The Fund is a nondiversified fund that seeks to achieve its objective to provide total return through long-term capital appreciation and current income by investing, under normal circumstances, at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the real estate or real estate-related industries (80% policy). The 80% policy is nonfundamental and may be changed without shareholder approval, but the Fund will provide shareholders with at least 60 days' notice before changing this 80% policy. The Fund intends to invest primarily in equity and equity-related securities issued by Global Real Estate Companies. The Fund does not invest directly in real estate. The Fund may invest in securities of issuers of any size, but typically will have more exposure to securities issued by large- and mid-capitalization companies. There is no guarantee, however, that the Fund will achieve its objective.

Global Real Estate Companies are companies that meet one of the following criteria:

Most of the Fund’s real estate securities portfolio consists of securities issued by REITs and REOCs that are listed on a securities exchange or traded over-the-counter (OTC). A REIT is a corporation or trust that invests in real estate, mortgages on real estate or shares issued by other REITs. REITs may be characterized as equity REITs (that is, REITs that primarily invest in land and improvements thereon), mortgage REITs (that is, REITs that primarily invest in mortgages on real estate and other real estate debt) or hybrid REITs, which invest in both land and improvements thereon and real estate mortgages. A REIT that meets the applicable requirements of the Internal Revenue Code of 1986, as amended (Code), may deduct dividends paid to shareholders, effectively enabling it to eliminate any entity-level federal income tax. As a result, REITs (like regulated investment companies such as the Fund) distribute a larger portion of their earnings to investors than other entities subject to federal income tax that cannot deduct such dividends. A REOC is a corporation or partnership (or an entity classified as such for federal tax purposes) that invests in real estate, mortgages on real estate or shares issued by REITs but also may engage in related or unrelated businesses. A REOC typically is structured as a “C” corporation under the Code and does not qualify for the pass-through tax treatment that is accorded a REIT. In addition, the value of the Fund’s securities issued by REOCs may be adversely affected by income streams derived from businesses other than real estate ownership. At times, the Fund may invest a significant portion of the Fund’s total assets in a limited number of issuers.

The Fund’s investment strategy utilizes a three-step bottom-up approach (researching individual issuers) with a strong focus on quality, risk and a valuation-based stock selection methodology, supported by a top-down (assessing the market environment) overlay as a check and a balance. The Macquarie Global Listed Real Estate Team (the “Team”) seeks to identify and capitalize on investment opportunities through an integrated approach to individual security-level analysis and long-term trends impacting real estate markets and cycles. The Team applies combined research sources in a disciplined and systematic manner, taking account of mis-pricing opportunities, long term value creation and the level of risk these assets bring to the Fund in both absolute and relative terms. The Team looks to manage risk by allocating capital where it believes it will have the most potential to drive returns which is ultimately in bottom-up stock and sector selection (as further described below) over and above top-down country and regional selection, where the Team feels performance is far harder to derive consistently.

A comprehensive and detailed bottom-up research approach is a key element of the Team’s investment process. The Team’s globally integrated, boots on the ground approach applies a rigorous focus on bottom-up company fundamentals to determine risk profile and growth prospects through a detailed review of their property portfolio, business strategy, organizational issues, balance sheet, liquidity, capital structure and management capabilities.   Analysts with primary coverage of a company are further complemented by team members with secondary coverage of the company which encourages peer review and debate and a strong top-down review from regional and global leadership. The Manager believes that bottom-up fundamental research is

central in producing the measures used to identify and rank opportunities suitable for investment, skew portfolio construction to quality and help manage risk. The Team believes that a top-down perspective is an important secondary component in building a global listed real estate portfolio and supporting the primary bottom-up function.

The Fund may invest up to 20% of its net assets in securities issued by companies outside of the real estate industry.

Many of the Global Real Estate Companies in which the Fund may invest have diverse operations, with products or services in markets other than their home market. 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.

Under normal circumstances, the Fund will invest at least 40% (or, if the portfolio managers deem it warranted by market conditions, at least 30%) of its total assets in securities of non-US issuers.

The Fund may use a variety of derivative instruments for various purposes. The Fund may, at any given time, use futures, options, forward contracts, and swaps in an effort to produce incremental earnings, hedge existing positions, increase or reduce market exposure, manage its exposure (increase or decrease) to various foreign currencies, or to otherwise manage the risks of the Fund’s investments. The Fund also may invest in companies that are offered in IPOs.

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.

Real estate industry risk — This risk includes, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage funds; overbuilding; extended vacancies of properties; increases in competition, property taxes, and operating expenses; changes in zoning laws; costs resulting from the cleanup of, and liability to third parties resulting from, environmental problems; casualty for condemnation losses; uninsured damages from floods, earthquakes, or other natural disasters; limitations on and variations in rents; and changes in interest rates.

Real assets industries risk — The risk that the value of a fund’s shares will be affected by factors particular to real assets securities and related industries or sectors (such as government regulation) and may fluctuate more widely than that of a fund that invests in a broad range of industries.

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

REOC-related risk — The risk that the value of a fund’s REOC securities may be adversely affected by certain of the same factors that adversely affect REITs and also that a fund may experience a decline in its income from REOC securities due to falling interest rates or decreasing dividend payments.

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.

Concentration risk — The risk that the Fund’s industry concentration in real asset securities will cause the Fund to be more exposed to developments affecting that single industry or industry group than a more broadly diversified fund would be. The Fund could experience greater volatility or may perform poorly during a downturn in the industry or industry group because it is more susceptible to the economic, regulatory, political, legal and other risks associated with those industries than a fund that invests more broadly.

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.

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.

Foreign risk — The risk that foreign securities (particularly in emerging markets) may be adversely affected 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.

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.

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.

Nondiversification risk — A nondiversified fund has the flexibility to invest as much as 50% of its assets in as few as two issuers with no single issuer accounting for more than 25% of the fund. The remaining 50% of its assets must be diversified so that no more than 5% of its assets are invested in the securities of a single issuer. Because a nondiversified fund may invest its assets in fewer issuers, the value of its shares may increase or decrease more rapidly than if it were fully diversified.

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.

Delaware Ivy Limited-Term Bond Fund, a series of Ivy Funds
 

On April 30, 2021, the fund in this prospectus (each, a Fund) became part of Delaware Funds by Macquarie​® and Delaware Management Company became the Fund’s investment manager.

What is the Fund’s investment objective?

Delaware Ivy Limited-Term Bond Fund seeks to provide current income consistent with preservation of capital.

What are the Fund’s fees and expenses?

The table below describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales-charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in Delaware Funds by Macquarie. 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.”

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. 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 88% of the average value of its portfolio.

What are the Fund’s principal investment strategies?

Under normal circumstances, the Delaware Ivy Limited-Term Bond Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in investment grade fixed income securities (80% policy), including, but not limited to, fixed income securities issued or guaranteed by the US government, its agencies or instrumentalities, and by US corporations. The Fund may also invest up to 30% of its net assets in foreign securities, including up to 10% of its net assets in securities of issuers located in emerging markets. The Fund may invest up to 20% of its net assets in below-investment-grade securities (also known as high yield or “junk” bonds). Additionally, the Fund may invest in mortgage-backed securities issued or guaranteed by the US government, its agencies or instrumentalities, government-sponsored corporations, and mortgage-backed securities issued by certain private, nongovernment entities. The Fund may also invest in securities that are backed by assets such as receivables on home equity and credit card loans, automobile, mobile home, recreational vehicle and other loans, wholesale dealer floor plans, and leases The Fund will maintain an average effective duration from one to three years.

Investment grade debt securities include those that are rated within the four highest ratings categories by Moody’s Investors Service, Inc. (Moody’s) or Standard & Poor’s Financial Services LLC (S&P) or that are unrated but determined by the Manager to be of equivalent quality.

The Fund may use a wide range of derivatives instruments, typically including options, futures contracts, options on futures contracts, forward foreign currency contracts, and swaps. The Fund will use derivatives for both hedging and nonhedging purposes. For example, the Fund may invest in: futures and options to manage duration and for defensive purposes, such as to protect gains or hedge against potential losses in the portfolio without actually selling a security, or to stay fully invested; forward foreign currency contracts to manage foreign currency exposure; interest rate swaps to neutralize the impact of interest rate changes; credit default swaps to hedge against a credit event, to gain exposure to certain securities or markets, or to enhance total return; and index swaps to enhance return or to effect diversification. The Fund will not use derivatives for reasons inconsistent with its investment objective and will limit its investments in derivatives instruments to 20% of its net assets.

The Manager may look at a number of factors in selecting securities for the Fund’s portfolio, beginning with a top-down (assessing the market environment) review of the broad economic and financial trends in the US and world markets. This process aids in the determination of economic fundamentals, which leads to sector allocation. Within a sector, the Manager typically considers the maturity and perceived liquidity of the security, the relative value of the security based on historical yield information, the creditworthiness of the particular issuer (if not backed by the full faith and credit of the Treasury), and prepayment risks for mortgage-backed securities and other debt securities with call provisions.

Generally, in determining whether to sell a security, the Manager uses the same type of analysis that it uses in buying securities, including review of the security’s valuation and the issuer’s creditworthiness. The Manager also may sell a security to take advantage of what it believes are more attractive investment opportunities, to reduce the Fund’s holding in that security or to raise cash.

The Manager may seek investment advice and recommendations from its affiliates: Macquarie Investment Management Europe Limited, Macquarie Investment Management Austria Kapitalanlage AG, and Macquarie Investment Management Global Limited (together, the “Affiliated Sub-Advisors”). The Manager may also permit these Affiliated Sub-Advisors to execute Fund security trades on behalf of the Manager and 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.

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:

Fixed income risk — The risk that bonds may decrease in value if interest rates increase; an issuer 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.

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.

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.

Mortgage-backed and asset-backed securities risk — The risk that the principal on mortgage-backed or asset-backed securities may be prepaid at any time, which will reduce the yield and market value. If interest rates fall, the rate of prepayments tends to increase as borrowers are motivated to pay off debt and refinance at new lower rates. Rising interest rates tend to extend the duration of mortgage-related securities, making them more sensitive to changes in interest rates. As a result, in a period of rising interest rates, a fund that holds mortgage-related securities may exhibit additional volatility.

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.

Prepayment risk — The risk that the principal on a bond that is held by a fund will be prepaid prior to maturity at a time when interest rates are lower than what that bond was paying. A fund may then have to reinvest that money at a lower interest rate.

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.

How has Delaware Ivy Limited-Term Bond 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-, and 10-year or 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. 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 800 523-1918 or by visiting our website at delawarefunds.com/performance.

Effective November 15, 2021, the Fund changed its investment strategy. Performance prior to November 15, 2021 reflects the Fund’s former strategy; its performance may have differed if the Fund’s current strategy had been in place.

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

As of June 30, 2022, the Fund’s Class A shares had a calendar year-to-date return of -3.97%. During the periods illustrated in this bar chart, Class A’s highest quarterly return was 2.36% for the quarter ended June 30, 2020 and its lowest quarterly return was -1.98% for the quarter ended June 30, 2013. The maximum Class A sales charge of 2.75%, 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, 2021

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.

Ask your salesperson or visit your financial intermediary’s website for more information.

Delaware Ivy Managed International Opportunities Fund, a series of Ivy Funds

On April 30, 2021, the fund in this prospectus (each, a Fund) became part of Delaware Funds by Macquarie​® and Delaware Management Company became the Fund’s investment manager.

What is the Fund’s investment objective?

Delaware Ivy Managed International Opportunities Fund seeks to provide capital growth and appreciation.

What are the Fund’s fees and expenses?

The table below describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. 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 Delaware Funds by Macquarie. 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.”

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. The example also assumes that your investment has a 5% return each year. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio turnover

The Fund does not incur transaction costs, such as commissions, when it buys and sells shares of the underlying funds (or “turns over” its portfolio), but it could incur transaction costs if it were to buy and sell other types of securities directly, including shares of unaffiliated funds. If the Fund were to buy and sell other types of securities directly, a higher portfolio turnover rate could indicate higher transaction costs and could result in higher taxes when Fund shares are held in a taxable account. Such costs, if incurred, would not be reflected in annual fund operating expenses or in the example and would affect the Fund's performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 36% of the average value of its portfolio.

What are the Fund’s principal investment strategies?

Delaware Ivy Managed International Opportunities Fund is a “fund-of-funds” that seeks to achieve its objective by providing investors a diversified portfolio of international stocks by investing primarily in Class R6 shares of certain Delaware Funds global/international mutual funds, as identified below. Each underlying Delaware Fund, in turn, invests in a diversified portfolio of foreign equity securities of issuers in developed as well as emerging markets, and, to a lesser extent, in US equity securities.

The Board, based upon the recommendation of Delaware Management Company (Manager), has authorized the following target allocation ranges for investment of the Fund’s assets in specific underlying funds, although the Manager expects the allocation will change over time.

The Manager monitors the Fund’s holdings and cash flow and, in general, manages them as needed in order to maintain the Fund’s target allocations. The Manager does not intend to trade actively among the underlying funds nor does it intend to attempt to capture short-term market opportunities. However, in seeking to enhance performance, the Manager may change allocations within the stated ranges. The Manager may modify the above-specified target asset allocations for the Fund and also may modify, from time to time, the underlying funds selected for the Fund. In addition, the percentage specified at the high end of the investment range for an underlying fund is a target, and from time to time, the Manager or market movements (or a combination of both) may cause the Fund’s investment in an underlying fund to temporarily exceed its target percentage.

By owning shares of the underlying funds, the Fund indirectly holds primarily equity securities of international, including emerging market and, to a lesser extent, US companies of any size.

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.

Fund of funds risk — The ability of the Fund to meet its investment objective is directly related to its target allocations among the underlying funds and the ability of those funds to meet their investment objectives. The Fund’s share price will likely change daily based on the performance of the underlying funds in which it invests. In general, the Fund is subject to the same risks as those of the underlying funds it holds. The Manager has the authority to select and replace underlying funds. The Manager is subject to a potential conflict of interest in doing so because the Manager serves as the investment manager to the underlying funds and the advisory fees paid by some of the underlying funds are higher than fees paid by other underlying funds. It is important to note, however, that the Manager has a fiduciary duty to the Fund and must act in the Fund’s best interests.

Foreign risk — The risk that foreign securities (particularly in emerging markets) may be adversely affected 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.

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.

Investment company securities risk — Investment in other investment companies typically reflects the risks of the types of securities in which the investment companies invest. When the Fund invests in another investment company, shareholders of the Fund bear their proportionate share of the other investment company’s fees and expenses as well as their share of the Fund’s fees and expenses, which could result in the duplication of certain fees.

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.

Additional information about principal investment strategies, other investments and risks of the underlying funds is provided in each underlying fund’s prospectus.

Effective February 11, 2014, the name of one of the Fund’s underlying funds, Ivy Pacific Opportunities Fund, was changed to Ivy Emerging Markets Equity Fund, and its strategy was changed to reflect a concentration in emerging market equity securities. Performance prior to such time in part reflects Ivy Pacific Opportunities Fund’s former strategy to invest primarily in Pacific region equity securities, and the Fund’s performance may have differed if Ivy Emerging Markets Equity Fund’s current strategy had been in place. In addition, in November 2014, Ivy International Growth Fund increased its emphasis on investment in the stocks of US companies. Also, effective January 1, 2015, the name of Ivy International Growth Fund was changed to Ivy Global Growth Fund and its strategy was changed to reflect a global focus. Performance prior to January 2015 reflects Ivy Global Growth Fund’s former international strategy and may have differed if Ivy Global Growth Fund’s current strategy that includes investing globally had been in place.

Effective November 15, 2021, the Fund changed its investment strategy. Performance prior to November 15, 2021 reflects the Fund’s former strategy; its performance may have differed if the Fund’s current strategy had been in place.

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

As of June 30, 2022, the Fund’s Class A shares had a calendar year-to-date return of -20.80%. During the periods illustrated in this bar chart, Class A’s highest quarterly return was 20.38% for the quarter ended June 30, 2020, and its lowest quarterly return was -25.36% for the quarter ended March 31, 2020.

Delaware Ivy Municipal Bond Fund, a series of Ivy Funds
 

On April 30, 2021, the fund in this prospectus (each, a Fund) became part of Delaware Funds by Macquarie​® and Delaware Management Company became the Fund’s investment manager.

What is the Fund’s investment objective?

Delaware Ivy Municipal Bond Fund seeks to provide the level of current income consistent with preservation of capital and that is not subject to federal income tax.

What are the Fund’s fees and expenses?

The table below describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below. You may qualify for sales-charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in Delaware Funds by Macquarie. 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.”

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. 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 60% of the average value of its portfolio.

What are the Fund’s principal investment strategies?

Delaware Ivy Municipal Bond Fund seeks to achieve its objective by investing, under normal circumstances, at least 80% of its net assets in municipal bonds. The Fund mainly invests in municipal bonds of investment grade and of any maturity. Municipal bonds are obligations issued by or on behalf of states, territories and possessions of the United States (including the District of Columbia, Puerto Rico, the US Virgin Islands and Guam), the interest on which is excludable from gross income for federal income tax purposes, although a portion of such interest may be an item of tax preference for purposes of the federal alternative minimum tax (AMT) (Tax Preference Item). Investment grade debt securities include debt securities 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 diversifies its holdings between two main types of municipal bonds:

The Manager attempts to enhance Fund performance by utilizing opportunities presented by the shape and slope of the yield curve. As an overlay to this core strategy, the Manager attempts to identify and capitalize on relative value opportunities that exist between sectors, states (including US possessions), security structures and ratings categories. The Manager monitors relative attractiveness to other taxable fixed-income asset classes, as well as municipal market supply/demand patterns, expectations of US Treasury (Treasury) market performance and overall market liquidity, tax policies and other technical factors, in seeking to identify opportunities for the Fund.

The Manager may look at a number of factors in selecting securities for the Fund’s portfolio. These include the security’s current coupon, the maturity, relative value and market yield of the security, the creditworthiness of the particular issuer or of the private company involved, the sector in which the security is identified, the structure of the security, including whether it has a call feature, and the state in which the security is issued.

The Manager seeks to emphasize prudent diversification among sectors, states, security structures, position sizes and ratings categories, in an attempt to reduce overall portfolio risk and performance volatility as well as to emphasize capital preservation. However, the Fund may invest significantly in municipal bonds payable from revenues derived from similar projects, such as those in the healthcare, transportation and utility sectors.

Generally, in determining whether to sell a security, the Manager uses the same type of analysis that it uses when buying securities to determine whether the security continues to be a desired investment for the Fund. 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.

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:

Fixed income risk — The risk that bonds may decrease in value if interest rates increase; an issuer 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.

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.

Prepayment risk — The risk that the principal on a bond that is held by a fund will be prepaid prior to maturity at a time when interest rates are lower than what that bond was paying. A fund may then have to reinvest that money at a lower interest rate.

Focus risk — The risk that, at times, the Fund may invest significantly in municipal bonds that finance similar types of projects, such as those in health care, life care, public power, education and transportation, among others, and in municipal bonds of issuers located in the same geographical area. A change that affects one project, such as proposed legislation on the financing of the project, a shortage of the materials needed for the project or a declining need for the project, likely would affect all similar projects, thereby increasing market risk.

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.

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.

Political, legislative or regulatory risk — The risk that the municipal securities market generally, or certain municipal securities in particular, may be significantly affected by adverse political, legislative or regulatory changes or litigation at the federal or state level.

Alternative minimum tax risk — The risk that the Fund may invest in municipal bonds the interest on which (and, therefore, any part of Fund dividends attributable to such interest) is a Tax Preference Item for shareholders subject to the AMT. If a Fund shareholder’s AMT liability is increased as a result of such treatment, that would reduce the Fund’s after-tax return to the shareholder.

Taxability risk — The risk that the Fund and the Manager rely on the opinion of an issuer’s bond counsel that the interest paid on the issuer’s securities will not be subject to federal income tax. However, after the Fund buys a security backed by such an opinion, distributions by the Fund may become taxable to shareholders due to noncompliant conduct by a bond issuer, unfavorable changes in federal tax laws, or adverse interpretations of tax laws by the Internal Revenue Service (IRS) or other authorities or because of other factors. Such adverse interpretations or actions could cause interest from a security to become taxable, possibly retroactively, subjecting shareholders to increased tax liability. In addition, such adverse interpretations or actions could cause the value of a security, and therefore, the value of the Fund’s shares, to decline.

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.

How has Delaware Ivy Municipal Bond 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-, and 10-year or 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. 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 800 523-1918 or by visiting our website at delawarefunds.com/performance.

Effective November 15, 2021, the Fund changed its investment strategy. Performance prior to November 15, 2021 reflects the Fund’s former strategy; its performance may have differed if the Fund’s current strategy had been in place.

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

As of June 30, 2022, the Fund’s Class A shares had a calendar year-to-date return of -11.36%. During the periods illustrated in this bar chart, Class A’s highest quarterly return was 2.94% for the quarter ended March 31, 2014, and its lowest quarterly return was -2.83% for the quarter ended June 30, 2013. The maximum Class A sales charge of 4.50%, 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.

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.

Tax information

Dividends paid from interest on municipal securities are excludable from gross income for federal income tax purposes. Dividends paid from interest paid on certain PABs may be a Tax Preference Item and, therefore, increase your AMT liability, if you are subject to the AMT.

The Fund’s distributions, from sources other than tax-exempt interest, generally are taxable to you as ordinary income, capital gains, or some combination of both, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an IRA, in which case your distributions may be taxed as ordinary income when withdrawn from the tax-advantaged account.

Payments to broker/dealers and other financial intermediaries

If you purchase shares of the Fund through a broker/dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker/dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
