Delaware Covered Call Strategy Fund

What is the Fund’s investment objective?

Delaware Covered Call Strategy Fund seeks long-term 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 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 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 Manager’s expense waivers and reimbursements for the 2-year contractual period and the total operating expenses without waivers for years 3 through 10. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 34% of the average value of its portfolio.

What are the Fund’s principal investment strategies?

The Fund invests in a portfolio of equity securities and writes (sells) call options on those securities. Under normal circumstances, the Fund writes (sells) call options on at least 80% of the Fund’s total assets (80% policy). The Fund normally writes (sells) covered call options listed on US exchanges on the equity securities held by the Fund to seek to lower the overall volatility of the Fund’s portfolio, protect the Fund from market declines, and generate income. The call options written (sold) by the Fund will generally have an exercise price that is above the market price of the underlying security at the time the option is written (sold). The Fund’s equity investments consist primarily of common stocks of large-size US companies (companies over $10 billion in market capitalization), certain of which may pay dividends, and US dollar-denominated equity securities of foreign issuers (i.e., American Depositary Receipts (ADRs)) traded on US securities exchanges. To a lesser extent, the Fund may also invest in and write (sell) covered call options on securities of mid- and small-capitalization issuers and exchange-traded funds (ETFs) that track certain market indices, such as the S&P 500. The nature of the Fund is such that it may be expected to underperform equity markets during periods of sharply rising equity prices; conversely, the Fund seeks to reduce losses relative to equity markets during periods of declining equity prices.

A call option gives the purchaser of the option the right to buy, and the writer, in this case, the Fund, the obligation to sell, the underlying security at the exercise price at any time prior to the expiration of the contract, regardless of the market price of the underlying security during the option period. Covered call options may be sold up to the number of shares of the equity securities held by the Fund.

In selecting investments, Ziegler Capital Management, LLC (ZCM), the Fund’s sub-advisor, considers the following, among other criteria: a) companies in an industry with a large market share or significant revenues that fit the Fund’s investment strategy; b) companies with new products or new management to replace underperforming management; c) recent or anticipated fundamental improvements in industry environment; and d) companies that are out of favor. Call options written by the Fund are designed to create income, lower the overall volatility of the Fund’s portfolio, and mitigate the impact of market declines. ZCM considers several factors when writing (selling) call options, including the overall equity market outlook, sector and/or industry attractiveness, individual security considerations, and relative and/or historical levels of option premiums. Premiums received for a call option the Fund writes will be treated as a short-term capital gain if the option expires.

The Fund may sell a security based on the following, among other criteria: a) an actual or anticipated significant decline in an issuer’s profitability and/or a significant negative outlook from management; b) a large appreciation in the stock price that leads to overvaluation relative to itself and its peers historically; c) significant management turnover at the senior level; or d) an industry-wide decrease in demand for an issuer’s products or services. ZCM writes call options based upon its outlook on the economy and stock market and analysis of individual stocks, which can impact the exercise price and expiration of a call option. Generally, higher implied volatility will lead to longer expirations, locking in potentially higher call premiums, whereas lower implied volatility will tend to lead to shorter-dated options. The writing of covered call options may result in frequent trading and a high portfolio turnover rate.

Additionally, from time to time, in pursuing its investment strategies, the Fund may hold significant investments (25% or more of its assets) in a specific market sector, including the information technology sector.

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.

Call options risk — The risk of potential losses if equity markets or an individual equity security do not move as expected and the potential for greater losses than if these techniques had not been used. By writing covered call options, a fund will not benefit from any potential increases in the value of a fund asset above the exercise price, but will bear the risk of declines in the value of the asset. Writing call options may expose a fund to additional costs. Derivatives may be difficult to sell, unwind or value.

Portfolio turnover risk — High portfolio turnover rates may increase a fund’s transaction costs and lower returns.

Exchange-traded fund risk — The risks of investing in an exchange-traded fund (ETF) typically reflect the risks of the types of instruments in which the ETF invests. Because ETFs are investment companies, funds will bear their proportionate share of the fees and expenses of an investment in an ETF. As a result, a fund’s expenses may be higher and performance may be lower.

Company size 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.

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

American depositary receipts risk — ADRs may involve many of the same risks as direct investments in foreign securities, including currency exchange fluctuations, less liquidity, more volatility, different governmental regulations, and the potential for political and economic instability.

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.

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 Covered Call Strategy Fund performed?

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

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

Updated performance information is available by calling 800 423-4026 or by visiting our website at delawarefunds.com/performance.

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

During the periods illustrated in this bar chart, Class A’s highest quarterly return was 10.69% for the quarter ended March 31, 2019, and its lowest quarterly return was -13.27% for the quarter ended Dec. 31, 2018. 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, 2019

* The Fund changed its broad-based securities index to the CBOE S&P 500 BuyWrite Index as of Oct. 4, 2019. The Fund elected to use the new index because it more closely reflected the Fund’s investment strategies.

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

The eligibility requirements are described in this Prospectus under “Choosing a share class” and on the Fund’s website. We may reduce or waive the minimums or eligibility requirements in certain cases.

Tax information

The Fund’s distributions 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.

These costs, which are not reflected in the annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 39% of the average value of its portfolio.

What are the Fund’s principal investment strategies?

The Fund invests, under normal circumstances, primarily in companies that the Fund believes are undervalued in the market relative to their long term potential. Under normal circumstances, the Fund will invest at least 80% of its net assets (including any borrowings for investment purposes) in equities (80% policy). For purposes of this 80% policy, equities may include common stock, preferred stock, equity-based exchange-traded funds (ETFs) and instruments that are convertible into common stock, or other instruments that represent an equity position in an issuer. The Fund seeks to generate income by investing in dividend paying companies.

The Fund generally uses a “bottom-up” approach in attempting to identify stocks that are undervalued. This means that the Fund generally identifies potential investments through fundamental research and analysis which includes, among other things, analyzing a company’s balance sheet, cash flow statements and competition within a company’s industry. The Fund also assesses a company’s corporate strategy and whether the company is operating in the interests of shareholders, as well as analyzing economic trends, interest rates, and industry diversification.

The Fund may sell a security if it becomes fully valued, its fundamentals have deteriorated or alternative investment opportunities become more attractive.

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

During the most recent fiscal year, the Fund’s portfolio turnover rate was 119% of the average value of its portfolio.

What are the Fund’s principal investment strategies?

The Fund invests in a portfolio of common stocks of companies that are located throughout the world, including the United States. Although the Fund primarily invests in stocks of US and foreign companies it may invest a significant amount in less-developed or emerging markets. The Fund may rely on the country where the issuer is incorporated, is headquartered or has its principal place of business in determining the location of an issuer. Additionally, in pursuing its investment strategies, the Fund may hold significant investments (25% or more of its assets) in a specific market sector, including the consumer staples sector. The Fund is a nondiversified fund.

The investment process is bottom-up, research-driven. The aim is to produce attractive risk-adjusted long-term returns by investing in understandable, quality businesses with mispriced earnings power. Understandable and quality businesses are reasonably straightforward and void of excessive complexity, excessive debt and relative margin instability. Mispricings occur when shorter term market fluctuations lead to a discount between a stock’s price and its fair value. Fair value is derived from such factors as the long term sales and future earnings potential of a business. Stock selection rests on an assessment of each company and its risk-return profile. Research is centered on understanding the nature and sustainability of how the company creates value, including the associated risks. Businesses identified as attractive are likely to display one or more of these favorable characteristics: solid earnings power and free cash flow generation, sustainable business models and competitive advantages, ability to reinvest at rates above the cost of capital, flexibility to restructure inefficiencies, potential to benefit from consolidation within their industries, and ability to gain market share from competitors. Sustainable businesses are businesses that have the ability to generate profits over the long term that also have the ability from time to time to redeploy part of earnings and reinvest into future advantageous areas of the business. An estimate for long-term earnings power is derived in order to calculate the fair value of a company. To compensate for unpredictable risks, the team aims to invest in companies that can be bought within an adequate safety margin to the estimated fair value. The portfolio managers strive to purchase stocks at a discount to what they deem to be fair value. The discount effectively provides a cushion to absorb potential stock price depreciation due to such factors as unexpected negative shifts in currency values and/or economic or political instability.

Screening is a method used for idea generation. A typical screen may exclude stocks under a certain market cap and then further applying numerous valuation, quality and growth metrics hurdles that would effectively reduce the universe further. Survivors would become candidates for fundamental research whereas in-depth analysis occurs to ultimately determine the attractiveness of a stock for potential portfolio admission.

The Fund's Manager may permit its affiliates, Macquarie Investment Management Global Limited (MIMGL) and Macquarie Fund 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.

Foreign and emerging markets risk — The risk that international investing (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. 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.

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

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

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.

What are the Fund’s fees and expenses?

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 Delaware Funds® by Macquarie.

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 Manager’s expense waivers and reimbursements for the 2-year contractual period and the total operating expenses without waivers for years 3 through 10. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 55% of the average value of its portfolio.

What are the Fund’s principal investment strategies?

The Fund primarily invests in common stocks that offer the potential for capital growth, current income or both. The Fund primarily invests in common stocks of large-size companies. The Fund may also invest in mid- and small-size companies. Some but not all of the companies the Fund invests in may regularly pay dividends.

The Fund generally uses a “bottom-up” approach to selecting investments. This means that the Fund generally identifies potential investments through fundamental research and analysis and also focuses on other issues, such as economic trends, interest rates, and market capitalization. Economic trends relate to the overall direction in which the economy is moving which may provide insights into the future direction of companies. Factors may include consumer confidence, employment, interest rates and inflation. In deciding whether to buy or sell securities, the Fund considers, among other things, the issuer’s financial strength, management, earnings growth or potential earnings growth and the issuer’s valuation relative to its fundamentals and peers.

The portfolio managers research individual companies and analyzes economic and market conditions, seeking to identify the securities that it believes are the best investments for the Fund. The Fund invests primarily in securities that the portfolio manager believes have long-term capital appreciation, or growth potential. The portfolio managers follow a value-oriented investment philosophy in selecting stocks for the Fund using a research-intensive approach that considers factors such as (i) a security price that reflects a market valuation that is judged to be below the estimated present or future value of the company; (ii) favorable earnings prospects and dividend yield potential; (iii) the financial condition of the issuer; and (iv) various qualitative factors.

Stocks that the Fund invests in may pay dividends. Common or ordinary stocks are securities that represent shares of ownership in a corporation. Stockholders may participate in a corporation’s profits through its distributions of dividends to stockholders, proportionate to the number of shares they own. The Fund may also own convertible securities. Convertible securities are usually preferred stocks or corporate bonds that can be exchanged for a set number of shares of common stock at a predetermined price. These securities offer higher appreciation potential than nonconvertible bonds and greater income potential than nonconvertible preferred stocks. The Fund may also invest in real estate investment trusts (REITs) and income-generating equity securities. REITs are pooled investment vehicles that invest primarily in income-producing real estate or real estate-related loans or interests.

The Fund may sell a security if it becomes fully valued, is no longer attractively valued, its fundamentals have deteriorated or alternative investments become more attractive.

The Fund’s Manager may permit its affiliates, Macquarie Investment Management Global Limited (MIMGL) and Macquarie Fund 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.

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.

Company size 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.

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.

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

The Manager is an indirect wholly owned subsidiary of Macquarie Group Limited (MGL).

How has Delaware Growth and Income Fund performed?

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

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

During the most recent fiscal year, the Fund’s portfolio turnover rate was 124% of the average value of its portfolio.

What are the Fund’s principal investment strategies?

The Fund seeks to achieve its investment objective by investing in a broadly diversified portfolio of common stocks of any market capitalization while also investing in derivatives to help manage investment risk. Under normal circumstances, the Fund will invest at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of US issuers and investments that provide exposure to such securities, including exchange-traded funds (80% policy). The Fund defines US issuers to include: (1) issuers that are incorporated or headquartered in the US; (2) issuers whose securities are principally traded in the US; (3) issuers with a majority of their business operations or assets in the US; and (4) issuers who derive a majority of their revenues or profits from the US. To a lesser extent, the Fund also may invest in the equity securities of foreign issuers. The portfolio management team also seeks to manage the Fund’s market risk and the risk of loss from significant events by investing in derivatives. The Fund may engage in active and frequent trading which may result in high portfolio turnover.

Wellington Management Company LLP (Wellington Management), the Fund’s sub-advisor, allocates the Fund’s equity investments across a range of equity market investment styles managed by Wellington Management that are focused on total return or growth of capital (underlying styles) to create a portfolio with broad market exposure.

Wellington Management allocates the Fund’s assets among the underlying styles to create a portfolio that represents a wide range of investment philosophies, companies, industries and market capitalizations. The underlying styles make investments based on their specific investment philosophies, for example, value, growth, high quality, or low volatility. The portfolio management team seeks to combine complementary underlying styles, monitoring the Fund’s risk profile and strategically rebalancing the portfolio. In selecting different underlying styles, Wellington Management considers, among other things, the relative level of an underlying style’s “active share” (i.e., the extent to which the underlying style’s holdings diverge from the underlying style’s benchmark index), and the “active share” of the Fund (i.e., the extent to which the Fund’s holdings diverge from the Fund’s benchmark index).

For each underlying style, Wellington Management has a distinct investment philosophy and analytical process to identify specific securities for purchase or sale based on internal proprietary research. The underlying styles generally invest in equity securities, but may also use derivatives for investment purposes. The underlying styles do not use derivatives solely for the purpose of creating leverage. Wellington Management’s investment personnel for each underlying style are responsible for selecting the Fund’s investments within their specific underlying styles. In selecting prospective investments for each underlying style, Wellington Management may employ qualitative and quantitative portfolio management techniques.

In addition to allocating the Fund’s assets to the underlying styles, Wellington Management seeks to manage the Fund’s aggregate investment risks, specifically, the risk of loss associated with markets generally as well as the risk of loss from significant events, by investing in derivatives. This strategy principally involves the purchase and sale of put and call options on indices and the purchase and sale of index futures contracts.

The use of derivatives is intended to hedge overall risks to the Fund, but not the risks associated with single or groups of investments or single or groups of underlying styles. As a result, Wellington Management’s derivatives strategy may protect the Fund from losses associated with a general market decline, but would not protect the Fund from losses resulting from a single investment or group of investments held by the Fund. The Fund may invest in cash and cash equivalents.

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.

Hedging risk — Hedging seeks to limit downside risks, but will also limit a fund’s return potential, especially during periods of rapid or large market gains. Hedging activities involve fees and expenses, which can further reduce returns. If a fund uses a hedging instrument at the wrong time or judges market conditions incorrectly, or the hedged instrument does not correlate to the risk sought to be hedged, the hedge might be unsuccessful, reduce a fund’s return, and/or create a loss.

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).

Asset allocation risk — The risk associated with the allocation of a fund’s assets amongst varying underlying styles. Portfolio managers may make investment decisions independently of one another, and may make conflicting investment decisions which could be detrimental to a fund’s performance.

Company size 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.

Exchange-traded fund risk — The risks of investing in an exchange-traded fund (ETF) typically reflect the risks of the types of instruments in which the ETFs invest. Because ETFs are investment companies, funds will bear their proportionate share of the fees and expenses of an investment in an ETF. As a result, a fund’s expenses may be higher and performance may be lower.

Portfolio turnover risk — High portfolio turnover rates may increase a fund’s transaction costs and lower returns.

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.

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 example also assumes that your investment has a 5% return each year and reflects the Manager’s expense waivers and reimbursements for the 2-year contractual period and the total operating expenses without waivers for years 3 through 10.

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 76% of the average value of its portfolio.

What are the Fund’s principal investment strategies?

The Fund primarily invests in a portfolio of common stocks and other equity securities of companies that are located outside of the United States. To a limited degree, the Fund may also invest in companies based in the United States. The Fund may rely on the country where the issuer is incorporated, is headquartered or has its principal place of business in determining the location of an issuer. Additionally, in pursuing its investment strategies, the Fund may hold significant investments (25% or more of its assets) in a specific market sector, including the consumer staples sector. The Fund is a nondiversified fund.

The investment process is bottom-up, research-driven. The aim is to produce attractive risk-adjusted long-term returns by investing in understandable, quality businesses with mispriced earnings power. Mispricings occur when shorter term market fluctuations lead to a discount between a stock's price and its fair value which is derived from such factors as the long term sales and future earnings potential of a business. Stock selection rests on an assessment of each company and its risk-return profile. Sustainability is defined as the Fund's ability to generate profits over the long term that also from time to time have the ability to redeploy part of earnings and reinvest into future advantageous areas of the business. Research is centered on understanding the nature and sustainability of how the company creates value, including the associated risks. Businesses identified as attractive are likely to display one or more of these favorable characteristics: solid earnings power and free cash flow generation, sustainable business models and competitive advantages, ability to reinvest at rates above the cost of capital, flexibility to restructure inefficiencies, potential to benefit from consolidation within their industries, and ability to gain market share from competitors. Sustainable businesses are businesses that have the ability to generate profits over the long term that also from time to time have the ability to redeploy part of earnings and reinvest into future advantageous areas of the business. An estimate for long-term earnings power is derived in order to calculate the fair value of a company. Fair value is defined as the estimated worth of a company based upon the company's earning potential and other variables. To compensate for unpredictable risks, the team aims to invest in companies that can be bought within an adequate safety margin to the estimated fair value. The portfolio managers strive to purchase stocks at a discount to what they deem to be fair value. The discount effectively provides a cushion to absorb potential stock price depreciation due to such factors as unexpected negative shifts in currency values and/or economic or political instability and negative shifts in company earnings.

Screening is a method used for idea generation. A typical screen may exclude stocks under a certain market cap and then applying numerous valuation, quality and growth metrics as hurdles that would effectively reduce the universe further. Survivors would become candidates for fundamental research whereas in-depth analysis occurs to ultimately determine the attractiveness of a stock for potential portfolio admission.

The Fund’s investment manager, Delaware Management Company (Manager), may permit its affiliates, Macquarie Investment Management Global Limited (MIMGL) and Macquarie Fund 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.

Foreign and emerging markets risk — The risk that international investing (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. 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.

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

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

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 International Fund performed?

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

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

Updated performance information is available by calling 800 423-4026 or by visiting our website at delawarefunds.com/performance.

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

During the periods illustrated in this bar chart, Class A’s highest quarterly return was 13.49% for the quarter ended Sept. 30, 2010, and its lowest quarterly return was -13.19% for the quarter ended Sept. 30, 2011. 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, 2019

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.

Purchase and redemption of Fund shares

You may purchase or redeem shares of the Fund on any day that the New York Stock Exchange (NYSE) is open for business (Business Day). Shares may be purchased or redeemed: through your financial advisor; or by mail (c/o Delaware Funds® by Macquarie, Raritan Plaza 1, Edison, NJ 08837-3620).

For Class A shares, the minimum initial investment is generally $1,000 and subsequent investments can be made for as little as $100. The minimum initial investment for IRAs, Uniform Gifts/Transfers to Minors Act accounts, direct deposit purchase plans, and automatic investment plans is $250 and through Coverdell Education Savings Accounts is $500, and subsequent investments in these accounts can be made for as little as $25. For Institutional Class and Class R6 shares (except those shares purchased through an automatic investment plan), there is no minimum initial purchase requirement, but certain eligibility requirements must be met. The eligibility requirements are described in this Prospectus under “Choosing a share class” and on the Fund’s website. We may reduce or waive the minimums or eligibility requirements in certain cases.

Tax information

The Fund’s distributions 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.

What are the Fund’s fees and expenses?

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 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 Manager’s expense waivers and reimbursements for the 2-year contractual period and the total operating expenses without waivers for years 3 through 10. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 47% of the average value of its portfolio.

What are the Fund’s principal investment strategies?

The Fund invests primarily in mid-size companies that the Manager believes offer attractive valuation and quality characteristics. Companies with attractive valuations are those that have a lower valuation than the company’s historical average valuation and a lower valuation than the company’s competitors. Companies with quality characteristics will make shareholder friendly use of its cash flow, which would include, but is not limited to: dividend payments or increases, share repurchases, and repayment of debt. The Fund also may invest in active or passive exchange-traded funds (ETFs) to gain exposure to such securities and in real estate investment trusts (REITs). The Fund may continue to hold stocks of companies that grow into larger companies and may also invest opportunistically in larger companies.

The Fund uses a “bottom-up” approach to selecting investments. The Fund uses fundamental research to search for companies that have one or more of the following: a strong balance sheet; experienced management; and stocks that are attractively priced. The Fund attempts to stay broadly diversified, but it may emphasize certain industry sectors based upon economic and market conditions.

The Fund may sell a stock if it becomes fully valued, its fundamentals have deteriorated or alternative investments become more attractive. The Fund may also sell a stock if it grows into a large, well-established company, although it may also continue to hold such a stock irrespective of its size.

The Manager may permit its affiliates, Macquarie Investment Management Global Limited (MIMGL) and Macquarie Fund 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.

Company size 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.

Exchange-traded fund risk — The risks of investing in an exchange-traded fund (ETF) typically reflect the risks of the types of instruments in which the ETF invests. Because ETFs are investment companies, funds will bear their proportionate share of the fees and expenses of an investment in an ETF. As a result, a Fund’s expenses may be higher and performance may be lower.

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.

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.

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.
