Disclosure of Fund expenses

For the six-month period from August 1, 2023 to January 31, 2024 (Unaudited)

The investment objective of the Funds is to seek to provide investors with total return.

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments, reinvested dividends, or other distributions; redemption fees; and exchange fees; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other Fund expenses. The following examples are intended to help you understand your ongoing costs (in dollars) of investing in a Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The examples are based on an investment of $1,000 invested at the beginning of the period and held for the entire six-month period from August 1, 2023 to January 31, 2024.

Actual expenses

The first section of the tables shown, “Actual Fund return,” provides information about actual account values and actual expenses. You may use the information in this section of the table, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The second section of the tables shown, “Hypothetical 5% return,” provides information about hypothetical account values and hypothetical expenses based on the Funds’ actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Funds’ actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in each Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the tables are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second section of each table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. The Funds’ expenses shown in the tables reflect fee waivers in effect and assume reinvestment of all dividends and distributions.

^†	Because actual returns reflect only the most recent six-month period, the returns shown may differ significantly from fiscal year returns.

In addition to the Funds’ expenses reflected on the previous page, each Fund also indirectly bears its portion of the fees and expenses of any investment companies (Underlying Funds), in which it invests. The tables on the previous page do not reflect the expenses of any Underlying Funds.

Delaware Corporate Bond Fund and
Delaware Extended Duration Bond Fund	January 31, 2024 (Unaudited)

Delaware Group^®Income Funds (Trust) is organized as a Delaware statutory trust and offers four series: Delaware Corporate Bond Fund, Delaware Extended Duration Bond Fund, Delaware Floating Rate Fund, and Delaware High-Yield Opportunities Fund. These financial statements and the related notes pertain to Delaware Corporate Bond Fund and Delaware Extended Duration Bond Fund (each, a Fund or collectively, the Funds). The Trust is an open-end investment company. Each Fund is considered diversified under the Investment Company Act of 1940, as amended (1940 Act), and offers Class A, Class C, Class R, Institutional Class, and Class R6 shares. Class A shares are sold with a maximum front-end sales charge of 4.50%. There is no front-end sales charge when you purchase $1 million or more of Class A shares. However, if Delaware Distributors, L.P. (DDLP) paid your financial intermediary a commission on your purchase of $1 million or more of Class A shares, you will have to pay a limited contingent deferred sales charge (Limited CDSC) of 1.00% if you redeem these shares within the first 18 months after your purchase, unless a specific waiver of the Limited CDSC applies. Class C shares have no upfront sales charge, but are sold with a contingent deferred sales charge (CDSC) of 1.00%, which will be incurred if redeemed during the first 12 months. Class R, Institutional Class, and Class R6 shares are not subject to a sales charge and are offered for sale exclusively to certain eligible investors. In addition, Class R6 shares do not pay any service fees, sub-accounting fees, and/or sub-transfer agency fees to any brokers, dealers, or other financial intermediaries.

1. Significant Accounting Policies

Each Fund follows accounting and reporting guidance under Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services — Investment Companies. The following accounting policies are in accordance with US generally accepted accounting principles (US GAAP) and are consistently followed by the Funds.

Security Valuation — Equity securities and exchange-traded funds (ETFs), except those traded on the Nasdaq Stock Market LLC (Nasdaq), are valued at the last quoted sales price as of the time of the regular close of the New York Stock Exchange on the valuation date. Equity securities and ETFs traded on the Nasdaq are valued in accordance with the Nasdaq Official Closing Price, which may not be the last sales price. If, on a particular day, an equity security or ETF does not trade, the mean between the bid and the ask prices will be used, which approximates fair value. US government and agency securities are valued at the mean between the bid and the ask prices, which approximates fair value. Open-end investment companies, other than ETFs, are valued at their published net asset value (NAV). Fixed income securities are generally priced based upon valuations provided by an independent pricing service or broker in accordance with methodologies included within Delaware Management Company (DMC)'s Pricing Policy (the Policy). Fixed income security valuations are then reviewed by DMC as part of its duties as each Fund's valuation designee and, to the extent required by the Policy and applicable regulation, fair valued consistent with the Policy. To the extent current market prices are not available, the pricing service may take into account developments related to the specific security, as well as transactions in comparable securities. Valuations for fixed income securities

Table of Contents

utilize matrix systems, which reflect such factors as security prices, yields, maturities, and ratings, and are supplemented by dealer and exchange quotations. Futures contracts are valued at the daily quoted settlement prices. Generally, other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by DMC. Subject to the oversight of the Trust's Board of Trustees (Board), DMC, as valuation designee, has adopted policies and procedures to fair value securities for which market quotations are not readily available consistent with the requirements of Rule 2a-5 under the 1940 Act. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures or suspension of trading in a security. Restricted securities and private placements are valued at fair value.

Federal Income Taxes — No provision for federal income taxes has been made as each Fund intends to continue to qualify for federal income tax purposes as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended, and make the requisite distributions to shareholders. Each Fund evaluates tax positions taken or expected to be taken in the course of preparing each Fund's tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are recorded as a tax benefit or expense in the current year. Management has analyzed each Fund’s tax positions taken or expected to be taken on each Fund’s federal income tax returns through the six months ended January 31, 2024, and for all open tax years (years ended July 31, 2020–July 31, 2023), and has concluded that no provision for federal income tax is required in each Fund’s financial statements. If applicable, each Fund recognizes interest accrued on unrecognized tax benefits in interest expense and penalties in “Other” on the “Statements of operations.” During the six months ended January 31, 2024, the Funds did not incur any interest or tax penalties.

Class Accounting — Investment income and common expenses are allocated to the various classes of each Fund on the basis of “settled shares” of each class in relation to the net assets of each Fund. Realized and unrealized gain (loss) on investments are allocated to the various classes of each Fund on the basis of daily net assets of each class. Distribution expenses relating to a specific class are charged directly to that class. Class R6 shares will not be allocated any expenses related to service fees, sub-accounting fees, and/or sub-transfer agency fees paid to brokers, dealers, or other financial intermediaries.

Foreign Currency Transactions — Transactions denominated in foreign currencies are recorded at the prevailing exchange rates on the valuation date. The value of all assets and liabilities denominated in foreign currencies is translated daily into US dollars at the exchange rate of such currencies against the US dollar. Transaction gains or losses resulting from changes in exchange rates during the reporting period or upon settlement of the foreign currency transaction are reported in operations for the current period. Each Fund generally bifurcates that portion of realized gains and losses on investments in debt securities which is due to changes in foreign exchange rates from that which is due to changes in market prices of debt securities. That portion of realized gains (losses), attributable to changes in foreign exchange rates, is included on the “Statements of operations” under “Net realized gain (loss) on foreign currencies.”

Delaware Corporate Bond Fund and
Delaware Extended Duration Bond Fund

1. Significant Accounting Policies (continued)

Each Fund reports certain foreign currency related transactions as components of realized gains (losses) for financial reporting purposes, whereas such components are treated as ordinary income (loss) for federal income tax purposes.

Derivative Financial Instruments — The Funds may invest in various derivative financial instruments. These instruments are used to obtain exposure to a security, commodity, index, market, and/or other assets without owning or taking physical custody of securities, commodities and/or other referenced assets or to manage market, equity, credit, interest rate, foreign currency exchange rate, commodity and/or other risks. Derivative financial instruments may give rise to a form of economic leverage and involve risks, including the imperfect correlation between the value of a derivative financial instrument and the underlying asset, possible default of the counterparty to the transaction or illiquidity of the instrument. Pursuant to Rule 18f-4 under the 1940 Act, among other things, the Funds intend to use either derivative financial instruments with embedded leverage in a limited manner or comply with an outer limit on fund leverage risk based on value-at-risk.

Segregation and Collateralization — In certain cases, based on requirements and agreements with certain exchanges and third-party broker-dealers, the Funds may deliver or receive collateral in connection with certain investments (e.g., futures contracts, forward foreign currency exchange contracts, options written, securities with extended settlement periods, and swaps). Certain countries require that cash reserves be held while investing in companies incorporated in that country. Cash collateral that has been pledged/received to cover obligations of the Funds under derivative contracts, if any, will be reported separately on the “Statements of assets and liabilities” as cash collateral due to/from broker. Securities collateral pledged for the same purpose, if any, is noted on the “Schedules of investments.”

Use of Estimates — The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the fair value of investments, the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and the differences could be material.

Other — Expenses directly attributable to a Fund are charged directly to each Fund. Other expenses common to various funds within the Delaware Funds by Macquarie^®(Delaware Funds) are generally allocated among such funds on the basis of average net assets. Management fees and certain other expenses are paid monthly. Security transactions are recorded on the date the securities are purchased or sold (trade date) for financial reporting purposes. Costs used in calculating realized gains and losses on the sale of investment securities are those of the specific securities sold. Dividend income is recorded on the ex-dividend date and interest income is recorded on an accrual basis. Income and capital gain distributions from any investment companies (Underlying Funds) in which each Fund invests are recorded on the ex-dividend date. Discounts and premiums on debt securities are accreted or amortized to interest income,

Table of Contents

respectively, over the lives of the respective securities using the effective interest method. Premiums on callable debt securities are amortized to interest income to the earliest call date using the effective interest method. Each Fund declares dividends daily from net investment income and pays the dividends monthly and declares and pays distributions from net realized gain on investments, if any, at least annually. Each Fund may distribute more frequently, if necessary for tax purposes. Dividends and distributions, if any, are recorded on the ex-dividend date.

Each Fund receives earnings credits from its transfer agent when positive cash balances are maintained, which may be used to offset transfer agent fees. If the amount earned is greater than $1, the expenses paid under this arrangement are included on the “Statements of operations” under “Dividend disbursing and transfer agent fees and expenses” with the corresponding expenses offset included under “Less expenses paid indirectly.”

2. Investment Management, Administration Agreements, and Other Transactions with Affiliates

In accordance with the terms of its respective investment management agreement, each Fund pays DMC, a series of Macquarie Investment Management Business Trust and the investment managers, an annual fee which is calculated daily and paid monthly based on each Fund’s average daily net assets as follows:

	Delaware Corporate Bond Fund			Delaware Extended Duration Bond Fund

On the next $500 million		0.4750	%		0.5000	%
On the next $1.5 billion		0.4500	%		0.4500	%
In excess of $2.5 billion		0.4250	%		0.4250	%

DMC has contractually agreed to waive all or a portion of its investment advisory fees and/or pay/reimburse expenses (excluding any distribution and service (12b-1) fees, acquired fund fees and expenses, taxes, interest, short sale dividend and interest expenses, brokerage fees, certain insurance costs, and nonroutine expenses or costs, including, but not limited to, those relating to reorganizations, litigation, conducting shareholder meetings, and liquidations), in order to prevent total annual fund operating expenses from exceeding the following percentages of each Fund's average daily net assets from August 1, 2023 (except as noted) through November 29, 2024.

DMC may seek investment advice and recommendations from its affiliates: Macquarie Investment Management Austria Kapitalanlage AG, Macquarie Investment Management Europe Limited, and Macquarie Investment Management Global Limited (together, the “Affiliated Sub-Advisors”). DMC may also permit these Affiliated Sub-Advisors to execute Fund security trades on its behalf and exercise investment discretion for securities in certain markets where DMC believes it will be beneficial to utilize an Affiliated Sub-Advisor’s specialized market knowledge. Although the Affiliated Sub-Advisors serve as sub-advisors, DMC has ultimate responsibility for all investment advisory services. For these services, DMC, not the Funds, pays each Affiliated Sub-Advisor a portion of its investment management fee.

Delaware Extended Duration Bond Fund		2,864

For the six months ended January 31, 2024, DDLP received gross CDSC commissions on redemptions of each Fund’s Class A and Class C shares, and these commissions were entirely used to offset upfront commissions previously paid by DDLP to broker/dealers on sales of those shares. The amounts received were as follows:

US GAAP defines fair value as the price that each Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. A three-level hierarchy for fair value measurements has been established based upon the transparency of inputs to the valuation of an asset or liability. Inputs may be observable or unobservable and refer broadly to the assumptions that market participants would use in pricing the asset or liability. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the asset or liability based on the best information available under the circumstances. Each Fund’s investment in its entirety is assigned a level based upon the observability of the inputs which are significant to the overall valuation. The three-level hierarchy of inputs is summarized as follows:

Level 1 -	Inputs are quoted prices in active markets for identical investments. (Examples: equity securities, open-end investment companies, futures contracts, and exchange-traded options contracts)

Level 2 -	Other observable inputs, including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks, and default rates) or other market-corroborated inputs. (Examples: debt securities, government securities, swap contracts, forward foreign currency exchange contracts, foreign securities utilizing international fair value pricing, broker-quoted securities, and fair valued securities)

Level 3 -	Significant unobservable inputs, including each Fund’s own assumptions used to determine the fair value of investments. (Examples: broker-quoted securities and fair valued securities)

Level 3 investments are valued using significant unobservable inputs. Each Fund may also use an income-based valuation approach in which the anticipated future cash flows of the investment are discounted to calculate fair value. Discounts may also be applied due to the nature or duration of any restrictions on the disposition of the investments. Valuations may also be based upon current market prices of securities that are comparable in coupon, rating, maturity, and industry. The derived value of a Level 3 investment may not represent the value which is received upon disposition and this could impact the results of operations.

During the six months ended January 31, 2024, there were no transfers into or out of Level 3 investments. Each Fund’s policy is to recognize transfers into or out of Level 3 investments based on fair value at the beginning of the reporting period.

A reconciliation of Level 3 investments is presented when each Fund has a significant amount of Level 3 investments at the beginning or end of the period in relation to each Fund’s net assets. As of January 31, 2024, there were no Level 3 investments.

5. Reorganization

On February 15-16, 2023, the Board approved a proposal to reorganize Delaware Ivy Crossover Credit Fund (the “Acquired Fund I”), a series of Delaware Ivy Funds, and Delaware Ivy Corporate Bond Fund (the “Acquired Fund II”), a series of Delaware Ivy Funds, (and together with Acquired Fund I, the “Acquired Funds”) with and into Delaware Corporate Bond Fund (the “Acquiring Fund”), a series of the Trust (the “Reorganizations”). On June 27, 2023 and September 8, 2023, Acquired Fund I shareholders and Acquired Fund II shareholders, respectively, approved the Reorganizations. Pursuant to an Agreement and Plan of Reorganization (the “Plan”): (i) all of the property and assets of the Acquired Funds were acquired by the Acquiring Fund, and (ii) the Trust, on behalf of Acquiring Fund, assumed the liabilities of the Acquired Funds, in exchange for shares of the Acquiring Fund. In accordance with the Plan, Acquired Funds liquidated and dissolved following the Reorganizations. The Reorganizations were accomplished by a tax-free exchange of shares on September 15, 2023 for the Acquired Fund I reorganization and October 27, 2023 for the Acquired Fund II reorganization. For financial reporting purposes, assets received and shares issued by the Acquiring Fund were recorded at fair value; however, the cost basis of the investments received from the Acquired Funds was carried forward to align ongoing reporting of the Acquiring Fund’s realized and unrealized gains and losses with amounts distributable to shareholders for tax purposes.

The share transactions associated with September 15, 2023 for Acquired Fund I Reorganizations were as follows:

	Acquired Fund I Net Assets		Acquired Fund I Shares Outstanding		Shares Converted to Acquiring Fund		Acquiring Fund Net Assets		Conversion Ratio
	Delaware Ivy Crossover Credit Fund				Delaware Corporate Bond Fund
Class A	$	2,544,171		308,384		237,279	$	224,008,795		0.5605

*	Class I shares of the Acquired Fund I were converted into Institutional Class shares of the Acquiring Fund.
**	Class Y shares of the Acquired Fund I were converted into Class A shares of the Acquiring Fund.

The net assets of the Acquired Fund I before the Reorganizations were $12,844,489. The Acquired Fund I net assets and shares outstanding presented on the table above do not include the shareholders that did not participate in the reorganization. The net assets of the Acquiring Fund immediately following the Acquired Fund I Reorganizations were $1,153,533,538.

The share transactions associated with October 27, 2023 for Acquired Fund II Reorganizations were as follows:

	Acquired Funds II Net Assets		Acquired Fund II Shares Outstanding		Shares Converted to Acquiring Fund		Acquiring Fund Net Assets		Conversion Ratio
	Delaware Ivy Corporate Bond Fund				Delaware Corporate Bond Fund
Class A	$	162,552,869		11,035,497		11,461,150	$	216,762,446		1.0373

Table of Contents

*	Class I shares of the Acquired Fund II were converted into Institutional Class shares of the Acquiring Fund.
**	Class Y shares of the Acquired Fund II were converted into Class A shares of the Acquiring Fund.

The net assets of the Acquired Fund II before the Reorganizations were $275,324,845. The Acquired Fund II net assets and shares outstanding presented on the table above do not include the shareholders that did not participate in the reorganization. The net assets of the Acquiring Fund immediately following the Acquired Fund II Reorganizations were $1,296,746,443.

Assuming the Reorganizations had been completed on August 1, 2023, the Acquiring Fund's pro forma results of operations for the six months ended January 31, 2024, would have been as follows:

Net investment income	$	29,288,995
Net realized loss on investments		(84,782,075	)
Net change in unrealized appreciation (depreciation)		140,792,205
Net increase in net assets resulting from operations	$	85,299,125

Because the combined investment portfolios have been managed as a single integrated portfolio since the acquisition was completed, it is not practical to separate the amounts of revenue and earnings of Acquired Funds that have been included in Acquiring Fund’s "Statements of operations" since the Reorganizations were consummated on September 15, 2023 for Acquired Fund I and October 27, 2023 for Acquired Fund II.

6. Line of Credit

Each Fund, along with certain other funds in the Delaware Funds (Participants), was a participant in a $355,000,000 revolving line of credit (Agreement) intended to be used for temporary or emergency purposes as an additional source of liquidity to fund redemptions of investor shares. Under the Agreement, the Participants were charged an annual commitment fee of 0.15%, which was allocated across the Participants based on a weighted average of the respective net assets of each Participant. The Participants were permitted to borrow up to a maximum of one-third of their net assets under the Agreement. Each Participant was individually, and not jointly, liable for its particular advances, if any, under the line of credit. The line of credit available under the Agreement expired on October 30, 2023.

On October 30, 2023, each Fund, along with the other Participants, entered into an amendment to the Agreement for a $335,000,000 revolving line of credit to be used as described above. It operates in substantially the same manner as the original Agreement. Under the amendment to the Agreement, the Participants are charged an annual commitment fee of 0.15%, which is allocated across the Participants based on a weighted average of the respective net assets of each Participant. The line of credit available under the Agreement expires on October 28, 2024.

6. Line of Credit (continued)

Each Fund had no amounts outstanding as of January 31, 2024, or at any time during the period then ended.

7. Derivatives

US GAAP requires disclosures that enable investors to understand: (1) how and why an entity uses derivatives; (2) how they are accounted for; and (3) how they affect an entity’s results of operations and financial position.

Futures Contracts — A futures contract is an agreement in which the writer (or seller) of the contract agrees to deliver to the buyer an amount of cash or securities equal to a specific dollar amount times the difference between the value of a specific security or index at the close of the last trading day of the contract and the price at which the agreement is made. Each Fund may use futures contracts in the normal course of pursuing its investment objective. Each Fund may invest in futures contracts to hedge its existing portfolio securities against fluctuations in value caused by changes in interest rates or market conditions. Upon entering into a futures contract, each Fund deposits cash or pledges US government securities to a broker, equal to the minimum “initial margin” requirements of the exchange on which the contract is traded. Subsequent payments are received from the broker or paid to the broker each day, based on the daily fluctuation in the value of the contract. These receipts or payments are known as “variation margin” and are recorded daily by the Funds as unrealized gains or losses until the contracts are closed. When the contracts are closed, the Funds record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Risks of entering into futures contracts include potential imperfect correlation between the futures contracts and the underlying securities and the possibility of an illiquid secondary market for these instruments. When investing in futures, there is reduced counterparty credit risk to the Funds because futures are exchange-traded and the exchange’s clearinghouse, as counterparty to all exchange-traded futures, guarantees against default. No futures contracts were open at January 31, 2024.

During the six months ended January 31, 2024, Delaware Corporate Bond Fund used futures contracts to hedge the Fund's existing portfolio securities against fluctuations in value caused by changes in interest rates or market conditions.

During the six months ended January 31, 2024, Delaware Corporate Bond Fund experienced net realized gains or losses attributable to futures contracts, which is disclosed on the “Statements of operations.”

	Long Derivative Volume
		Delaware Corporate Bond Fund
Futures contracts (average notional value)		4,834,427

8. Securities Lending

Each Fund, along with other funds in the Delaware Funds, may lend its securities pursuant to a security lending agreement (Lending Agreement) with The Bank of New York Mellon (BNY Mellon). At the time a security is loaned, the borrower must post collateral equal to the required percentage of the market value of the loaned security, including any accrued interest. The required percentage is: (1) 102% with respect to US securities and foreign securities that are denominated and payable in US dollars; and (2) 105% with respect to foreign securities. With respect to each loan, if on any business day the aggregate market value of securities collateral plus cash collateral held is less than the aggregate market value of the securities which are the subject of such loan, the borrower will be notified to provide additional collateral by the end of the following business day, which, together with the collateral already held, will be not less than the applicable initial collateral requirements for such security loan. If the aggregate market value of securities collateral and cash collateral held with respect to a security loan exceeds the applicable initial collateral requirement, upon the request of the borrower, BNY Mellon must return enough collateral to the borrower by the end of the following business day to reduce the value of the remaining collateral to the applicable initial collateral requirement for such security loan. As a result of the foregoing, the value of the collateral held with respect to a loaned security on any particular day, may be more or less than the value of the security on loan. The collateral percentage with respect to the market value of the loaned security is determined by the security lending agent.

Cash collateral received by each Fund of the Trust is generally invested in a series of individual separate accounts, each corresponding to a fund. The investment guidelines permit each separate account to hold certain securities that would be considered eligible securities for a money market fund. Cash collateral received is generally invested in government securities; certain obligations issued by government sponsored enterprises; repurchase agreements collateralized by US Treasury securities; obligations issued by the central government of any Organization for Economic Cooperation and Development (OECD) country or its agencies, instrumentalities, or establishments; obligations of supranational organizations; commercial paper, notes, bonds, and other debt obligations; certificates of deposit, time deposits, and other bank obligations; certain money market funds; and asset-backed securities. Each Fund can also accept US government securities and letters of credit (non-cash collateral) in connection with securities loans.

Delaware Extended Duration Bond Fund

8. Securities Lending (continued)

In the event of default or bankruptcy by the lending agent, realization and/or retention of the collateral may be subject to legal proceedings. In the event the borrower fails to return loaned securities and the collateral received is insufficient to cover the value of the loaned securities and provided such collateral shortfall is not the result of investment losses, the lending agent has agreed to pay the amount of the shortfall to each Fund or, at the discretion of the lending agent, replace the loaned securities. Each Fund continues to record dividends or interest, as applicable, on the securities loaned and is subject to changes in value of the securities loaned that may occur during the term of the loan. Each Fund has the right under the Lending Agreement to recover the securities from the borrower on demand. With respect to security loans collateralized by non-cash collateral, each Fund receives loan premiums paid by the borrower. With respect to security loans collateralized by cash collateral, the earnings from the collateral investments are shared among each Fund, the security lending agent, and the borrower. Each Fund records security lending income net of allocations to the security lending agent and the borrower.

Each Fund may incur investment losses as a result of investing securities lending collateral. This could occur if an investment in each collateral investment account defaulted or became impaired. Under those circumstances, the value of each Fund’s cash collateral account may be less than the amount each Fund would be required to return to the borrowers of the securities and each Fund would be required to make up for this shortfall.

At January 31, 2024, each Fund had no securities out on loan.

9. Credit and Market Risks

The impact of COVID-19, and other infectious illness outbreaks that may arise in the future, could adversely affect the economies of many nations or the entire global economy, individual issuers and capital markets in ways that cannot necessarily be foreseen.

Each Fund invests in high yield fixed income securities, which are securities rated lower than BBB- by Standard & Poor's Financial Service LLC, lower than Baa3 by Moody’s Investors Service, or similarly rated by another nationally recognized statistical rating organization. Investments in these higher yielding securities are generally accompanied by a greater degree of credit risk than higher rated securities. Additionally, lower rated securities may be more susceptible to adverse economic and competitive industry conditions than investment grade securities.

When interest rates rise, fixed income securities (i.e. debt obligations) generally will decline in value. These declines in value are greater for fixed income securities with longer maturities or durations. 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. A fund may be subject to a greater risk of rising interest rates when interest rates are low or inflation rates are high or rising.

Table of Contents

Each Fund invests in bank loans and other securities that may subject them to direct indebtedness risk, the risk that the Funds 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. Loans that are fully secured offer the Funds more protection than unsecured loans in the event of nonpayment of scheduled interest or principal, although there is no assurance that the liquidation of collateral from a secured loan would satisfy the corporate borrower’s obligation, or that the collateral can be liquidated. Some loans or claims may be in default at the time of purchase. Certain of the loans and the other direct indebtedness acquired by the Funds may involve revolving credit facilities or other standby financing commitments that obligate the Funds to pay additional cash on a certain date or on demand. These commitments may require each Fund to increase its investment in a company at a time when the Funds might not otherwise decide to do so (including at a time when the company’s financial condition makes it unlikely that such amounts will be repaid). To the extent that each Fund is committed to advance additional funds, it will at all times hold and maintain cash or other high grade debt obligations in an amount sufficient to meet such commitments. When a loan agreement is purchased, the Funds may pay an assignment fee. On an ongoing basis, the Funds may receive a commitment fee based on the undrawn portion of the underlying line of credit portion of a loan agreement. Prepayment penalty fees are received upon the prepayment of a loan agreement by the borrower. Prepayment penalty, facility, commitment, consent, and amendment fees are recorded to income as earned or paid.

As the Funds may be required to rely upon another lending institution to collect and pass on to the Funds amounts payable with respect to the loan and to enforce the Funds’ rights under the loan and other direct indebtedness, an insolvency, bankruptcy, or reorganization of the lending institution may delay or prevent the Funds from receiving such amounts. The highly leveraged nature of many loans may make them especially vulnerable to adverse changes in economic or market conditions. Investments in such loans and other direct indebtedness may involve additional risk to the Funds. There were no unfunded loan commitments at the six months ended January 31, 2024.

Each Fund invests in certain obligations that may have liquidity protection designed to ensure that the receipt of payments due on the underlying security is timely. Such protection may be provided through guarantees, insurance policies, or letters of credit obtained by the issuer or sponsor through third parties, through various means of structuring the transaction, or through a combination of such approaches. The Funds will not pay any additional fees for such credit support, although the existence of credit support may increase the price of a security.

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, which may exceed amounts disclosed on the "Statements of assets and liabilities", 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

9. Credit and Market Risks (continued)

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).

Each Fund may invest up to 15% of its net assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A promulgated under the Securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair each Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. While maintaining oversight, each Board has delegated to DMC, the day-to-day functions of determining whether individual securities are liquid for purposes of the Funds’ limitation on investments in illiquid securities. Securities eligible for resale pursuant to Rule 144A, which are determined to be liquid, are not subject to the Funds’ 15% limit on investments in illiquid securities. Rule 144A securities have been identified on the “Schedules of investments.”

10. Contractual Obligations

Each Fund enters into contracts in the normal course of business that contain a variety of indemnifications. Each Fund's maximum exposure under these arrangements is unknown. However, each Fund has not had prior claims or losses pursuant to these contracts. Management has reviewed each Fund's existing contracts and expects the risk of loss to be remote.

11. Subsequent Events

Management has determined that no material events or transactions occurred subsequent to January 31, 2024, that would require recognition or disclosure in the Funds’ financial statements.

Board Consideration of Investment Management Agreement and Sub-Advisory Agreements at a Meeting Held on August 8-10, 2023

At a meeting held on August 8-10, 2023 (the “Annual Contract Renewal Meeting”), the Board of Trustees (the “Board”), including a majority of Trustees each of whom is not an “interested person” as defined under the Investment Company Act of 1940 (the “Independent Trustees”), approved the renewal of the Delaware Corporate Bond Fund and Delaware Extended Duration Bond Fund (each a “Fund” and collectively, the “Funds”) Investment Management Agreement with Delaware Management Company (“DMC”) and the Sub-Advisory Agreements with Macquarie Investment Management Global Limited (“MIMGL”), Macquarie Investment Management Austria Kapitalanlage AG (“MIMAK”) and Macquarie Investment Management Europe Limited (“MIMEL”) (together, the “Affiliated Sub-Advisers”).

Prior to the Annual Contract Renewal Meeting, including at a Board meeting held in May 2023, the Trustees conferred extensively among themselves and with representatives of DMC about these matters. Also, the Board was assisted by the Equity Investments Committee and the Fixed Income Multi-Asset Sub-Advised Funds Investments Committee (each an “Investment Committee” and together, the “Investment Committees”), with each Investment Committee assisting the full Board in reviewing investment performance and other matters throughout the year. The Independent Trustees were also assisted in their evaluation of the Investment Management Agreement and the Sub-Advisory Agreements by independent legal counsel, from whom they received separate legal advice and with whom they met separately.

In providing information to the Board, DMC was guided by a detailed set of requests for information submitted to them by independent legal counsel on behalf of the Independent Trustees at the start of the Board’s annual contract renewal process earlier in 2023. Prior to the Annual Contract Renewal Meeting, and in response to the requests, the Board received and reviewed materials specifically relating to the renewal of the Investment Management Agreement and the Sub-Advisory Agreements. In considering and approving the Investment Management Agreement and the Sub-Advisory Agreements, the Trustees considered the information they believed relevant, including but not limited to the information discussed below. The Board considered not only the specific information presented in connection with the Annual Contract Renewal Meeting and the review process for the Investment Management Agreement and the Sub-Advisory Agreements, but also the knowledge gained over time through interaction with DMC about various topics. In this regard, the Board reviewed reports of DMC at each of its quarterly meetings, which included information about, among other things, Fund performance, investment strategies, and expenses. In addition, the Investment Committees confer with portfolio managers at various times throughout the year. In considering information relating to the approval of the Funds’ Investment Management Agreement and the Sub-Advisory Agreements, the Independent Trustees also received information from an independent fund consultant, JDL Consultants, LLC (“JDL”).

The Board did not identify any particular information or consideration that was all-important or controlling, and each individual Trustee may have attributed different weights to various factors.

Board Consideration of Investment Management Agreement and Sub-Advisory Agreements at a Meeting Held on August 8-10, 2023 (continued)

After its deliberations, the Board, including the Independent Trustees, unanimously approved the continuation of the Investment Management Agreement and the Sub-Advisory Agreements for a one-year term. The following summarizes a number of important, but not necessarily all, factors considered by the Board in support of its approval.

Nature, extent, and quality of services. The Board received and considered various information regarding the nature, extent, and quality of the advisory services provided to the Funds by DMC under their Investment Management Agreement and the experience of the officers and employees of DMC who provide these services, including the Funds’ portfolio managers. The Board’s review included consideration of DMC’s investment process and oversight and research and analysis capabilities, and its ability to attract and retain skilled investment professionals. The Board also considered information regarding DMC’s programs for risk management, including investment, operational, liquidity, derivatives (as applicable), valuation, and compliance risks. The Board received information with respect to the cybersecurity program and business continuity plans of DMC and its affiliates.

In addition, the Board considered certain non-advisory services that DMC and its affiliates provide to the Delaware Funds by Macquarie complex (the “Delaware Funds”). Among other things, these services include third party service provider oversight, transfer agency, internal audit, valuation, portfolio trading, and legal and compliance functions. The Board noted DMC’s responsibility for overseeing the preparation of the Delaware Funds’ registration statement and supplements thereto and shareholder reports; responsibility for periodic filings with regulators; organizing Board meetings and preparing materials for such Board meetings; and furnishing analytical and other support to assist the Board. The Board took into account the benefits to shareholders of investing in Funds that are part of a family of funds managed by an affiliate of Macquarie Group Ltd. (“Macquarie”), the parent company of DMC, and the resources available to DMC as part of Macquarie’s global asset management business.

The Board received and considered various information with respect to the services provided by the Affiliated Sub-Advisers under the Sub-Advisory Agreements and the credentials and experience of the officers and employees of the Affiliated Sub-Advisers who provide these services. The Board considered the division of responsibilities between DMC and the Affiliated Sub-Advisers and the oversight provided by DMC. The Board also considered the expertise of the Affiliated Sub-Advisers with respect to certain asset classes and/or investment styles. The Board noted that the Affiliated Sub-Advisers are part of Macquarie’s global investment platform that has offices and personnel that are located around the world. These Affiliated Sub-Advisers provide research, investment and trading analysis on the markets and economies of various countries in which the Funds may invest, make recommendations regarding securities, provide portfolio management services and assist with security trades, as applicable. The Board took into account that the Sub-Advisory Agreements may benefit the Funds and their shareholders by permitting DMC to use the resources and talents of the Affiliated Sub-Advisers in managing the Funds.

Table of Contents

The Board also received and considered information about the nature and extent of services offered and fee rates charged by DMC to other types of clients with investment strategies similar to those of the Funds. In this regard, the Board received information about the significantly greater scope of services, and compliance, reporting and other legal and regulatory obligations and risks of managing registered investment companies compared with those associated with managing assets of other types of clients, including third-party sub-advised fund clients, unregistered funds and separately managed accounts.

The Board concluded that, overall, it was satisfied with the nature, extent, and quality of services provided (and expected to be provided) to the Funds by DMC and the Affiliated Sub-Advisers.

Investment performance. The Board received and considered information with respect to the investment performance of the Funds, including performance reports and discussions with portfolio managers at meetings of the Board’s Investment Committees throughout the year as well as reports provided by Broadridge Financial Solutions, Inc., an independent investment company data provider (“Broadridge”), furnished for the Annual Contract Renewal Meeting. The Broadridge reports prepared for the Funds’ institutional share class showed its investment performance in comparison to the institutional share class of a group of similar funds (the “Performance Universe”). The Board received a description of the methodology used by Broadridge to select the peer funds in the Performance Universe. Comparative annualized performance for the Fund was shown for the past 1-, 3-, 5-, and 10-year or since inception periods, as applicable, ended December 31, 2022.

Delaware Corporate Bond Fund. The Performance Universe for the Fund consisted of the Fund and all retail and institutional BBB-rated corporate debt funds, regardless of asset size or primary channel of distribution. The Board noted that the Broadridge report comparison showed that the Fund’s total return for the 1-year period was in the fourth quartile of its Performance Universe and for the 3-, 5-, and 10-year periods was in the second quartile of its Performance Universe. The Broadridge report comparison showed that the Fund’s total return for the 1-year period was below the median of its Performance Universe and for the 3-, 5-, and 10-year periods was above the median of its Performance Universe. The Board also noted that the Fund outperformed its benchmark index for the 1-, 3-, 5-, and 10-year periods. The Board noted that the Fund was generally performing in line with its benchmark index during the periods under review. The Board noted the explanations from DMC and the Affiliated Sub-Advisers concerning the reasons for the Fund’s relative performance versus its Performance Universe for the 1-year period.

Delaware Extended Duration Bond Fund. The Performance Universe for the Fund consisted of the Fund and all retail and institutional BBB-rated corporate debt funds, regardless of asset size or primary channel of distribution. The Board noted that the Broadridge report comparison showed that the Fund’s total return for the 1-, 3-, and 5-year periods was in the fourth quartile of its Performance Universe and for the 10-year period was in the second quartile of its Performance Universe. The Broadridge report comparison showed that the Fund’s total return for the 1-, 3-, and 5-year periods was below the median of its Performance Universe and for the 10-year period was above the median of its Performance Universe. The Board also noted that the Fund underperformed its benchmark index for the 1-, 5-, and 10-year periods and outperformed its benchmark index for the 3-year period. The Board noted the explanations from

DMC and from the Affiliated Sub-Advisers concerning the reasons for the Fund’s relative performance versus its Performance Universe and benchmark index for the various periods.

Comparative expenses. The Board received and considered expense data for the Funds. DMC provided the Board with information on pricing levels and fee structures for each Fund as of its most recently completed fiscal year. The Broadridge total expenses, for comparative consistency, were shown by Broadridge for Institutional Class shares and comparative total expenses including 12b-1 and non-12b-1 service fees. The Board also considered the comparative analysis of contractual management fees and actual total expense ratios of each Fund versus contractual management fees and actual total expense ratios of a group of peer funds as selected by Broadridge (the “Expense Group”). In reviewing comparative costs, each Fund’s contractual management fee and the actual management fee incurred by the Fund were compared with the contractual management fees (assuming all funds in the Expense Group were similar in size to the Fund) and actual management fees, taking into account any applicable breakpoints and fee waivers, with the Fund’s expense universe, which is comprised of the Fund, its Expense Group and all other similar institutional funds, excluding outliers (the “Expense Universe”). Each Fund’s total expenses were also compared with those of its Expense Universe. The Board also received and considered information regarding each Fund’s net operating expense ratios and its various components, including actual management fees, custodian and other non-management fees, and Rule 12b-1 and non-Rule 12b-1 shareholder service fees.

Delaware Corporate Bond Fund. The expense comparisons for the Fund showed that its actual management fee was below the median of its Expense Universe and its actual total expenses were above its Expense Group average. It was noted that consistent with DMC’s waiver methodology, its advisory fee waivers, if any, were at the fund level and not class level.

Delaware Extended Duration Bond Fund. The expense comparisons for the Fund showed that its actual management fee was below the median of its Expense Universe and its actual total expenses were above its Expense Group average. It was noted that consistent with DMC’s waiver methodology, its advisory fee waivers, if any, were at the fund level and not class level.

The Board noted that DMC, and not the Funds, pays the sub-advisory fees to the Affiliated Sub-Advisers and, accordingly, that the retention of the Affiliated Sub-Advisers does not increase the fees and expenses incurred by the Funds.

Based on its consideration of the factors and information it deemed relevant, including those described here, the Board determined that the compensation payable to DMC under the Investment Management Agreement and to the Affiliated Sub-Advisers under the Sub-Advisory Agreements was reasonable.

economies of scale are reflected in the level of management fees charged. DMC discussed its advisory fee pricing and structure for the Delaware Funds, including the current breakpoints. The Board noted that, as of March 31, 2023, the Delaware Corporate Bond Fund’s net assets exceeded its second breakpoint level and that breakpoints result in a lower advisory fee than would otherwise be the case in the absence of breakpoints, when the asset levels specified in the breakpoints schedule are exceeded. The Board noted that each Fund may also benefit from economies of scale through initial fee setting, fee waivers and expense reimbursements, as well as DMC’s investment in its business, including investments in business infrastructure, technology and cybersecurity.

Management profitability. The Board received and considered the Investment Management Profitability Analysis that addressed the overall profitability of DMC’s business in providing management and other services to each Fund and the Delaware Funds as a whole, including the methodology used by DMC in allocating costs for the purpose of determining profitability. The Board noted DMC’s changes to its cost allocation methodology for its profitability analysis and the explanations for such changes. The Board also reviewed a report prepared by JDL regarding DMC’s profitability as compared to certain peer fund complexes and the Independent Trustees discussed DMC’s profitability in such context with representatives from JDL. The Board recognized that calculating and comparing profitability at the individual fund level is difficult; that DMC’s profit, if any, can vary significantly depending on the particular fund; and that DMC’s support for, and commitment to, a fund is not solely dependent on the profits realized as to that fund.

The Board also received and considered information about the portion of the total management fee that was retained by DMC after payment of the fee to the Affiliated Sub-Advisers for sub-advisory services. In assessing the reasonableness of this amount, the Board received and evaluated information about the nature and extent of the responsibilities retained and risk assumed by DMC and not delegated to or assumed by the Affiliated Sub-Advisers. Given the affiliation between DMC and the Affiliated Sub-Advisers, the Board ascribed limited relevance to the allocation of fees between them.

Based on its review, the Board determined that DMC’s profitability was not excessive in light of the nature, extent and quality of the services provided to the Funds.

Ancillary benefits. The Board received and considered information regarding the extent to which DMC and its affiliates might derive ancillary benefits from fund operations, including the potential for procuring additional business as a result of the prestige and visibility associated with its role as investment manager to the Delaware Funds; the benefits from allocation of fund brokerage to improve trading efficiencies; the portfolio transactions executed through “soft dollar” arrangements; and the fees that various affiliates received for serving as transfer agent and for overseeing fund accounting and financial administration services to the Delaware Funds. The Board considered that it receives periodic reports from DMC that include a representation that any soft dollar arrangements are consistent with regulatory requirements. The Board received information from DMC regarding its view of the performance of its affiliates in providing transfer agent and fund accounting and financial administration oversight services and the organizational structure employed to provide these services pursuant to their contracts with the Funds.

Board Consideration of Investment Management Agreement and Sub-Advisory Agreements at a Meeting Held on August 8-10, 2023 (continued)

Based on its consideration of the factors and information it deemed relevant, including the costs of providing investment management and other services to the Funds and the ongoing commitment of DMC and its affiliates to the Funds, the Board did not find that any ancillary benefits received by DMC and its affiliates, including the Affiliated Sub-Advisers, were unreasonable.

Conclusion. Based on its review, consideration and evaluation of all factors it believed relevant, including the above-described factors and conclusions, the Board, including all of the Independent Trustees, approved the continuation of DMC’s Investment Management Agreement and of the Affiliated Sub-Advisers’ Sub-Advisory Agreements for an additional one-year period.

Disclosure of Fund expenses

For the six-month period from August 1, 2023 to January 31, 2024 (Unaudited)

The investment objective of the Fund is to seek high current income and, secondarily, long-term total return.

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments, reinvested dividends, or other distributions; redemption fees; and exchange fees; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire six-month period from August 1, 2023 to January 31, 2024.

Actual expenses

The first section of the table shown, “Actual Fund return,” provides information about actual account values and actual expenses. You may use the information in this section of the table, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first section under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical example for comparison purposes

The second section of the table shown, “Hypothetical 5% return,” provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. The Fund’s expenses shown in the table reflect fee waivers in effect and assume reinvestment of all dividends and distributions.

In addition to the Fund’s expenses reflected above, the Fund also indirectly bears its portion of the fees and expenses of any investment companies (Underlying Funds), in which it invests. The table above does not reflect the expenses of any Underlying Funds.

Notes to financial statements

Delaware Floating Rate Fund

January 31, 2024 (Unaudited)

Delaware Group^®Income Funds (Trust) is organized as a Delaware statutory trust and offers four series: Delaware Corporate Bond Fund, Delaware Extended Duration Bond Fund, Delaware Floating Rate Fund, and Delaware High-Yield Opportunities Fund. These financial statements and the related notes pertain to Delaware Floating Rate Fund (Fund). The Trust is an open-end investment company. The Fund is considered diversified under the Investment Company Act of 1940, as amended (1940 Act), and offers Class A, Class C, Class R, Institutional Class, and Class R6 shares. Class A shares are sold with a maximum front-end sales charge of 2.75%. There is no front-end sales charge when you purchase $1 million or more of Class A shares. However, if Delaware Distributors, L.P. (DDLP) paid your financial intermediary a commission on your purchase of $1 million or more of Class A shares, you will have to pay a limited contingent deferred sales charge (Limited CDSC) of 1.00% if you redeem these shares within the first 18 months after your purchase, unless a specific waiver of the Limited CDSC applies. Class C shares have no upfront sales charge, but are sold with a contingent deferred sales charge (CDSC) of 1.00%, which will be incurred if redeemed during the first 12 months. Class R, Institutional Class, and Class R6 shares are not subject to a sales charge and are offered for sale exclusively to certain eligible investors. In addition, Class R6 shares do not pay any service fees, sub-accounting fees, and/or sub-transfer agency fees to any brokers, dealers, or other financial intermediaries.

1. Significant Accounting Policies

The Fund follows accounting and reporting guidance under Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services — Investment Companies. The following accounting policies are in accordance with US generally accepted accounting principles (US GAAP) and are consistently followed by the Fund.

Security Valuation — Equity securities and exchange-traded funds (ETFs), except those traded on the Nasdaq Stock Market LLC (Nasdaq), are valued at the last quoted sales price as of the time of the regular close of the New York Stock Exchange on the valuation date. Equity securities and ETFs traded on the Nasdaq are valued in accordance with the Nasdaq Official Closing Price, which may not be the last sales price. If, on a particular day, an equity security or ETF does not trade, the mean between the bid and the ask prices will be used, which approximates fair value. Equity securities listed on a foreign exchange are normally valued at the last quoted sales price on the valuation date. Fixed income securities are generally priced based upon valuations provided by an independent pricing service or broker in accordance with methodologies included within Delaware Management Company (DMC)’s Pricing Policy (the Policy). Fixed income security valuations are then reviewed by DMC as part of its duties as the Fund’s valuation designee and, to the extent required by the Policy and applicable regulation, fair valued consistent with the Policy. To the extent current market prices are not available, the pricing service may take into account developments related to the specific security, as well as transactions in comparable securities. Open-end investment companies, other than ETFs, are valued at their published net asset value (NAV). Forward foreign currency exchange contracts are valued at the mean between the bid and the ask prices, which approximates fair value.

Table of Contents

Notes to financial statements

Delaware Floating Rate Fund

1. Significant Accounting Policies (continued)

Interpolated values are derived when the settlement date of the contract is an interim date for which quotations are not available. Valuations for fixed income securities utilize matrix systems, which reflect such factors as security prices, yields, maturities, and ratings, and are supplemented by dealer and exchange quotations. Generally, other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by DMC. Subject to the oversight of the Trust’s Board of Trustees (Board), DMC, as valuation designee, has adopted policies and procedures to fair value securities for which market quotations are not readily available consistent with the requirements of Rule 2a-5 under the 1940 Act. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures or suspension of trading in a security. The Fund may use fair value pricing more frequently for securities traded primarily in non-US markets because, among other things, most foreign markets close well before the Fund values its securities, generally as of 4:00pm ET. The earlier close of these foreign markets gives rise to the possibility that significant events, including broad market moves, government actions or pronouncements, aftermarket trading, or news events may have occurred in the interim. Whenever such a significant event occurs, the Fund may value foreign securities using fair value prices based on third-party vendor modeling tools (international fair value pricing). Restricted securities and private placements are valued at fair value.

Federal Income Taxes — No provision for federal income taxes has been made as the Fund intends to continue to qualify for federal income tax purposes as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended, and make the requisite distributions to shareholders. The Fund evaluates tax positions taken or expected to be taken in the course of preparing the Fund’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are recorded as a tax benefit or expense in the current year. Management has analyzed the Fund’s tax positions taken or expected to be taken on the Fund’s federal income tax returns through the six months ended January 31, 2024, and for all open tax years (years ended July 31, 2020–July 31, 2023), and has concluded that no provision for federal income tax is required in the Fund’s financial statements. If applicable, the Fund recognizes interest accrued on unrecognized tax benefits in interest expense and penalties in “Other” on the “Statement of operations.” During the six months ended January 31, 2024, the Fund did not incur any interest or tax penalties.

Class Accounting — Investment income and common expenses are allocated to the various classes of the Fund on the basis of “settled shares” of each class in relation to the net assets of the Fund. Realized and unrealized gain (loss) on investments are allocated to the various classes of the Fund on the basis of daily net assets of each class. Distribution expenses relating to a specific class are charged directly to that class. Class R6 shares will not be allocated any expenses related to service fees, sub-accounting fees, and/or sub-transfer agency fees paid to brokers, dealers, or other financial intermediaries.

Table of Contents

Underlying Funds — The Fund may invest in other investment companies (Underlying Funds) to the extent permitted by the 1940 Act. The Underlying Funds in which the Fund may invest include ETFs. The Fund will indirectly bear the investment management fees and other expenses of the Underlying Funds.

Foreign Currency Transactions — Transactions denominated in foreign currencies are recorded at the prevailing exchange rates on the valuation date. The value of all assets and liabilities denominated in foreign currencies is translated daily into US dollars at the exchange rate of such currencies against the US dollar. Transaction gains or losses resulting from changes in exchange rates during the reporting period or upon settlement of the foreign currency transaction are reported in operations for the current period. The Fund generally bifurcates that portion of realized gains and losses on investments in debt securities which is due to changes in foreign exchange rates from that which is due to changes in market prices of debt securities. That portion of realized gains (losses), attributable to changes in foreign exchange rates, is included on the “Statement of operations” under “Net realized gain (loss) on foreign currencies.” For foreign equity securities, the realized gains and losses are included on the “Statement of operations” under “Net realized gain (loss) on investments.” The Fund reports certain foreign currency related transactions as components of realized gains (losses) for financial reporting purposes, whereas such components are treated as ordinary income (loss) for federal income tax purposes.

Derivative Financial Instruments — The Fund may invest in various derivative financial instruments. These instruments are used to obtain exposure to a security, commodity, index, market, and/or other assets without owning or taking physical custody of securities, commodities and/or other referenced assets or to manage market, equity, credit, interest rate, foreign currency exchange rate, commodity and/or other risks. Derivative financial instruments may give rise to a form of economic leverage and involve risks, including the imperfect correlation between the value of a derivative financial instrument and the underlying asset, possible default of the counterparty to the transaction or illiquidity of the instrument. Pursuant to Rule 18f-4 under the 1940 Act, among other things, the Fund intends to use either derivative financial instruments with embedded leverage in a limited manner or comply with an outer limit on fund leverage risk based on value-at-risk.

Segregation and Collateralization — In certain cases, based on requirements and agreements with certain exchanges and third-party broker-dealers, the Fund may deliver or receive collateral in connection with certain investments (e.g., futures contracts, forward foreign currency exchange contracts, options written, securities with extended settlement periods, and swaps). Certain countries require that cash reserves be held while investing in companies incorporated in that country. Cash collateral that has been pledged/received to cover obligations of the Fund under derivative contracts, if any, will be reported separately on the “Statement of assets and liabilities” as cash collateral due to/from broker. Securities collateral pledged for the same purpose, if any, is noted on the “Schedule of investments.”

1. Significant Accounting Policies (continued)

Other — Expenses directly attributable to the Fund are charged directly to the Fund. Other expenses common to various funds within the Delaware Funds by Macquarie^®(Delaware Funds) are generally allocated among such funds on the basis of average net assets. Management fees and certain other expenses are paid monthly. Security transactions are recorded on the date the securities are purchased or sold (trade date) for financial reporting purposes. Costs used in calculating realized gains and losses on the sale of investment securities are those of the specific securities sold. Dividend income is recorded on the ex-dividend date and interest income is recorded on an accrual basis. Income and capital gain distributions from any Underlying Funds in which the Fund invests are recorded on the ex-dividend date. Discounts and premiums on debt securities are accreted or amortized to interest income, respectively, over the lives of the respective securities using the effective interest method. Premiums on callable debt securities are amortized to interest income to the earliest call date using the effective interest method. The Fund declares dividends daily from net investment income and pays the dividends monthly and declares and pays distributions from net realized gain on investments, if any, at least annually. The Fund may distribute more frequently, if necessary for tax purposes. Dividends and distributions, if any, are recorded on the ex-dividend date.

The Fund receives earnings credits from its transfer agent when positive cash balances are maintained, which may be used to offset transfer agent fees. If the amount earned is greater than $1, the expenses paid under this arrangement are included on the “Statement of operations” under “Dividend disbursing and transfer agent fees and expenses” with the corresponding expenses offset included under “Less expenses paid indirectly.”

2. Investment Management, Administration Agreements, and Other Transactions with Affiliates

In accordance with the terms of its investment management agreement, the Fund pays DMC, a series of Macquarie Investment Management Business Trust and the investment manager, an annual fee which is calculated daily and paid monthly at the rates of 0.50% on the first $500 million of average daily net assets of the Fund, 0.475% on the next $500 million, 0.45% on the next $1.5 billion, and 0.425% on average daily net assets in excess of $2.5 billion.

Prior to November 30, 2023, DMC contractually agreed to waive all or a portion of its investment advisory fees and/or pay/reimburse expenses to 0.62% of the Fund’s Class R6 shares’ average daily net assets. These waivers and reimbursements may only be terminated by agreement of DMC and the Fund. The waivers and reimbursements are accrued daily and received monthly.

	Operating expense limitation as a percentage of average daily net assets

*	Effective November 30, 2023. Prior to November 30, 2023, the expense limitation for Class R6 shares was 0.62%.

DMC may seek investment advice and recommendations from its affiliates: Macquarie Investment Management Austria Kapitalanlage AG, Macquarie Investment Management Europe Limited, and Macquarie Investment Management Global Limited (together, the “Affiliated Sub-Advisors”). DMC may also permit these Affiliated Sub-Advisors to execute Fund security trades on its behalf and exercise investment discretion for securities in certain markets where DMC believes it will be beneficial to utilize an Affiliated Sub-Advisor’s specialized market knowledge. Although the Affiliated Sub-Advisors serve as sub-advisors, DMC has ultimate responsibility for all investment advisory services. For these services, DMC, not the Fund, pays each Affiliated Sub-Advisor a portion of its investment management fee.

Delaware Investments Fund Services Company (DIFSC), an affiliate of DMC, provides fund accounting and financial administrative oversight services to the Fund. For these services, effective October 1, 2023, DIFSC’s fees are calculated daily and paid monthly, based on the aggregate daily net assets of all funds within the Delaware Funds at the following annual rates: 0.0050% of the first $60 billion; 0.00475% of the next $30 billion; and 0.0015% of aggregate average daily net assets in excess of $90 billion (Total Fee). Prior to October 1, 2023, DIFSC’s annual rates were: 0.00475% of the first $35 billion; 0.0040% of the next $10 billion; 0.0025% of the next $45 billion; and 0.0015% of aggregate average daily net assets in excess of $90 billion. Each fund in the Delaware Funds pays a minimum of $4,000, which, in aggregate, is subtracted from the Total Fee. Each fund then pays its portion of the remainder of the Total Fee on a relative NAV basis. This amount is included on the “Statement of operations” under “Accounting and administration expenses.” For the six months ended January 31, 2024, the Fund paid $12,662 for these services.

DIFSC is also the transfer agent and dividend disbursing agent of the Fund. For these services, DIFSC’s fees are calculated daily and paid monthly, based on the aggregate daily net assets of the retail funds within the Delaware Funds at the following annual rates: 0.014% of the first $20 billion; 0.011% of the next $5 billion; 0.007% of the next $5 billion; 0.004% of the next $20 billion; 0.002% of the next $25 billion; and 0.0015% of average daily net assets in excess of $75 billion. The fees payable to DIFSC under the shareholder services agreement described above are allocated among all retail funds in the Delaware Funds on a relative NAV basis. This amount is included on the “Statement of operations” under “Dividend disbursing and transfer agent fees and expenses.” For the six months ended January 31, 2024, the Fund paid $18,781 for these services. Pursuant to a sub-transfer agency agreement between DIFSC and BNY Mellon Investment Servicing (US) Inc. (BNYMIS), BNYMIS provides certain sub-transfer agency services to the Fund. Sub-transfer agency fees are paid by the Fund and are also included on the “Statement of operations” under “Dividend disbursing and transfer agent fees and expenses.” The fees are calculated daily and paid as invoices are received on a monthly or quarterly basis.

Pursuant to a distribution agreement and distribution plan, the Fund pays DDLP, the distributor and an affiliate of DMC, an annual 12b-1 fee of 0.25%, 1.00%, and 0.50% of the average daily net assets of the Class A, Class C, and Class R shares, respectively. The fees are calculated daily and paid monthly. Institutional Class and Class R6 shares do not pay 12b-1 fees.

As provided in the investment management agreement, the Fund bears a portion of the cost of certain resources shared with DMC, including the cost of internal personnel of DMC and/or its affiliates that provide legal and regulatory reporting services to the Fund. For the six months ended January 31, 2024, the Fund paid $7,370 for internal legal and regulatory reporting services provided by DMC and/or its affiliates’ employees. This amount is included on the “Statement of operations” under “Legal fees.”

For the six months ended January 31, 2024, DDLP earned $5,663 for commissions on sales of the Fund’s Class A shares. For the six months ended January 31, 2024, DDLP received gross CDSC commissions of $3,160 and $519 on redemptions of the Fund’s Class A and Class C shares, respectively, and these commissions were entirely used to offset upfront commissions previously paid by DDLP to broker/dealers on sales of those shares.

Trustees’ fees include expenses accrued by the Fund for each Trustee’s retainer and meeting fees. Certain officers of DMC, DIFSC, and DDLP are officers and/or Trustees of the Trust. These officers and Trustees are paid no compensation by the Fund.

In addition to the management fees and other expenses of the Fund, the Fund indirectly bears the investment management fees and other expenses of any Underlying Funds, including ETFs, in which it invests. The amount of these fees and expenses incurred indirectly by the Fund will vary based upon the expense and fee levels of any Underlying Funds and the number of shares that are owned of any Underlying Funds at different times.

3. Investments

For the six months ended January 31, 2024, the Fund made purchases and sales of investment securities other than short-term investments and US government securities as follows:

Purchases		$	204,289,454
Sales			203,317,698

Cost of investments	$	596,136,785
Aggregate unrealized appreciation of investments	$	9,393,139
Aggregate unrealized depreciation of investments		(9,042,629	)

For federal income tax purposes, capital loss carryforwards may be carried forward and applied against future capital gains. At July 31, 2023, the Fund had capital loss carryforwards available to offset future realized capital gains as follows:

Loss carryforward character
Short-term		Long-term		Total
$	20,639,325	$	24,091,846	$	44,731,171

US GAAP defines fair value as the price that the Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. A three-level hierarchy for fair value measurements has been established based upon the transparency of inputs to the valuation of an asset or liability. Inputs may be observable or unobservable and refer broadly to the assumptions that market participants would use in pricing the asset or liability. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the asset or liability based on the best information available under the circumstances. The Fund’s investment in its entirety is assigned a level based upon the observability of the inputs which are significant to the overall valuation. The three-level hierarchy of inputs is summarized as follows:

Level 1 -	Inputs are quoted prices in active markets for identical investments. (Examples: equity securities, open-end investment companies, futures contracts, and exchange-traded options contracts)

Level 2 -	Other observable inputs, including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities,

	prepayment speeds, loss severities, credit risks, and default rates) or other market-corroborated inputs. (Examples: debt securities, government securities, swap contracts, forward foreign currency exchange contracts, foreign securities utilizing international fair value pricing, broker-quoted securities, and fair valued securities)

Level 3 -	Significant unobservable inputs, including the Fund’s own assumptions used to determine the fair value of investments. (Examples: broker-quoted securities and fair valued securities)

Level 3 investments are valued using significant unobservable inputs. The Fund may also use an income-based valuation approach in which the anticipated future cash flows of the investment are discounted to calculate fair value. Discounts may also be applied due to the nature or duration of any restrictions on the disposition of the investments. Valuations may also be based upon current market prices of securities that are comparable in coupon, rating, maturity, and industry. The derived value of a Level 3 investment may not represent the value which is received upon disposition and this could impact the results of operations.

The following table summarizes the valuation of the Fund’s investments by fair value hierarchy levels as of January 31, 2024:

	Level 1		Level 2		Level 3		Total
Securities
Assets:
Common Stock	$	198,660	$	—	$	—	$	198,660

Total Value of Securities	$	47,277,880	$	548,662,143	$	547,272	$	596,487,295

During the six months ended January 31, 2024, there were no transfers into or out of Level 3 investments. The Fund’s policy is to recognize transfers into or out of Level 3 investments based on fair value at the beginning of the reporting period.

A reconciliation of Level 3 investments is presented when the Fund has a significant amount of Level 3 investments at the beginning or end of the period in relation to the Fund’s net assets. Management has determined not to provide a reconciliation of Level 3 investments as the Level 3 investments were not considered significant to the Fund’s net assets at the beginning or end of the period. Management has determined not to provide additional disclosure on Level 3 inputs since the Level 3 investments are not considered significant to the Fund’s net assets at the end of the period.

5. Line of Credit

The Fund, along with certain other funds in the Delaware Funds (Participants), was a participant in a $355,000,000 revolving line of credit (Agreement) intended to be used for temporary or emergency purposes as an additional source of liquidity to fund redemptions of investor shares. Under the Agreement, the Participants were charged an annual commitment fee of 0.15%, which was allocated across the Participants based on a weighted average of the respective net assets of each Participant. The Participants were permitted to borrow up to a maximum of one-third of their net assets under the Agreement. Each Participant was individually, and not jointly, liable for its particular advances, if any, under the line of credit. The line of credit available under the Agreement expired on October 30, 2023.

On October 30, 2023, the Fund, along with the other Participants, entered into an amendment to the Agreement for a $335,000,000 revolving line of credit to be used as described above. It operates in substantially the same manner as the original Agreement. Under the amendment to the Agreement, the Participants are charged an annual commitment fee of 0.15%, which is allocated across the Participants based on a weighted average of the respective net assets of each Participant. The line of credit available under the Agreement expires on October 28, 2024.

The Fund had no amounts outstanding as of January 31, 2024, or at any time during the period then ended.

6. Derivatives

Forward Foreign Currency Exchange Contracts — The Fund may enter into forward foreign currency exchange contracts as a way of managing foreign exchange rate risk. The Fund may enter into these contracts to fix the US dollar value of a security that it has agreed to buy or sell for the period between the date the trade was entered into and the date the security is delivered and paid for. The Fund may also enter into these contracts to hedge the US dollar value of securities it already owns that are denominated in foreign currencies. In addition, the Fund may enter into these contracts to facilitate or expedite the settlement of portfolio transactions. The change in value is recorded as an unrealized gain or loss. When the contract is closed, a realized gain or loss is recorded equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed.

The use of forward foreign currency exchange contracts does not eliminate fluctuations in the underlying prices of the securities, but does establish a rate of exchange that can be achieved in the future. Although forward foreign currency exchange contracts limit the risk of loss due to an unfavorable change in the value of the hedged currency, they also limit any potential gain that might result should the value of the currency change favorably. In addition, the Fund could be exposed to risks if the counterparties to the contracts are unable to meet the terms of their contracts. The Fund’s maximum risk of loss from counterparty credit risk is the value of its

Table of Contents

currency exchanged with the counterparty. The risk is generally mitigated by having a netting arrangement between the Fund and the counterparty and by the posting of collateral by the counterparty to the Fund to cover the Fund’s exposure to the counterparty. No forward foreign currency exchange contracts were outstanding at January 31, 2024.

During the six months ended January 31, 2024, the Fund entered into forward foreign currency exchange contracts to hedge the US dollar value of securities it already owns that are denominated in foreign currencies to decrease exposure to foreign currencies.

During the six months ended January 31, 2024, the Fund experienced net realized and unrealized gains or losses attributable to forward foreign currency exchange contracts, which are disclosed on the “Statement of operations.”

The table below summarizes the average daily balance of derivative holdings by the Fund during the six months ended January 31, 2024:

		Long Derivative Volume				Short Derivative Volume
Forward foreign currency exchange contracts (average notional value)		$	—			$	67,029

7. Securities Lending

The Fund, along with other funds in the Delaware Funds, may lend its securities pursuant to a security lending agreement (Lending Agreement) with The Bank of New York Mellon (BNY Mellon). At the time a security is loaned, the borrower must post collateral equal to the required percentage of the market value of the loaned security, including any accrued interest. The required percentage is: (1) 102% with respect to US securities and foreign securities that are denominated and payable in US dollars; and (2) 105% with respect to foreign securities. With respect to each loan, if on any business day the aggregate market value of securities collateral plus cash collateral held is less than the aggregate market value of the securities which are the subject of such loan, the borrower will be notified to provide additional collateral by the end of the following business day, which, together with the collateral already held, will be not less than the applicable initial collateral requirements for such security loan. If the aggregate market value of securities collateral and cash collateral held with respect to a security loan exceeds the applicable initial collateral requirement, upon the request of the borrower, BNY Mellon must return enough collateral to the borrower by the end of the following business day to reduce the value of the remaining collateral to the applicable initial collateral requirement for such security loan. As a result of the foregoing, the value of the collateral held with respect to a loaned security on any particular day, may be more or less than the value of the security on loan. The collateral percentage with respect to the market value of the loaned security is determined by the security lending agent.

Cash collateral received by the Fund is generally invested in an individual separate account. The investment guidelines permit each separate account to hold certain securities that would be considered eligible securities for a money market fund. Cash collateral received is generally

7. Securities Lending (continued)

invested in government securities; certain obligations issued by government sponsored enterprises; repurchase agreements collateralized by US Treasury securities; obligations issued by the central government of any Organization for Economic Cooperation and Development (OECD) country or its agencies, instrumentalities, or establishments; obligations of supranational organizations; commercial paper, notes, bonds, and other debt obligations; certificates of deposit, time deposits, and other bank obligations; certain money market funds; and asset-backed securities. The Fund can also accept US government securities and letters of credit (non-cash collateral) in connection with securities loans.

In the event of default or bankruptcy by the lending agent, realization and/or retention of the collateral may be subject to legal proceedings. In the event the borrower fails to return loaned securities and the collateral received is insufficient to cover the value of the loaned securities and provided such collateral shortfall is not the result of investment losses, the lending agent has agreed to pay the amount of the shortfall to the Fund or, at the discretion of the lending agent, replace the loaned securities. The Fund continues to record dividends or interest, as applicable, on the securities loaned and is subject to changes in value of the securities loaned that may occur during the term of the loan. The Fund has the right under the Lending Agreement to recover the securities from the borrower on demand. With respect to security loans collateralized by non-cash collateral, the Fund receives loan premiums paid by the borrower. With respect to security loans collateralized by cash collateral, the earnings from the collateral investments are shared among the Fund, the security lending agent, and the borrower. The Fund records security lending income net of allocations to the security lending agent and the borrower.

The Fund may incur investment losses as a result of investing securities lending collateral. This could occur if an investment in the collateral investment account defaulted or became impaired. Under those circumstances, the value of the Fund’s cash collateral account may be less than the amount the Fund would be required to return to the borrowers of the securities and the Fund would be required to make up for this shortfall.

At January 31, 2024, the Fund had no securities out on loan.

8. Credit and Market Risks

The Fund invests a portion of its assets in high yield fixed income securities, which are securities rated lower than BBB- by Standard & Poor’s Financial Services LLC and Baa3 by Moody’s Investors Service, Inc., or similarly rated by another nationally recognized statistical rating organization. Investments in these higher yielding securities are generally accompanied by a greater degree of credit risk than higher rated securities. Additionally, lower rated securities may be more susceptible to adverse economic and competitive industry conditions than investment grade securities.

Table of Contents

The Fund invests in certain obligations that may have liquidity protection designed to ensure that the receipt of payments due on the underlying security is timely. Such protection may be provided through guarantees, insurance policies, or letters of credit obtained by the issuer or sponsor through third parties, through various means of structuring the transaction, or through a combination of such approaches. The Fund will not pay any additional fees for such credit support, although the existence of credit support may increase the price of a security.

The Fund invests in bank loans and other securities that may subject it to direct indebtedness risk, the risk that the Fund 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. Loans that are fully secured offer the Fund more protection than unsecured loans in the event of nonpayment of scheduled interest or principal, although there is no assurance that the liquidation of collateral from a secured loan would satisfy the corporate borrower’s obligation, or that the collateral can be liquidated. Some loans or claims may be in default at the time of purchase. Certain of the loans and the other direct indebtedness acquired by the Fund may involve revolving credit facilities or other standby financing commitments that obligate the Fund to pay additional cash on a certain date or on demand. These commitments may require the Fund to increase its investment in a company at a time when the Fund might not otherwise decide to do so (including at a time when the company’s financial condition makes it unlikely that such amounts will be repaid). To the extent that the Fund is committed to advance additional funds, it will at all times hold and maintain cash or other high grade debt obligations in an amount sufficient to meet such commitments. When a loan agreement is purchased, the Fund may pay an assignment fee. On an ongoing basis, the Fund may receive a commitment fee based on the undrawn portion of the underlying line of credit portion of a loan agreement. Prepayment penalty fees are received upon the prepayment of a loan agreement by the borrower. Prepayment penalty, facility, commitment, consent, and amendment fees are recorded to income as earned or paid.

As the Fund may be required to rely upon another lending institution to collect and pass on to the Fund amounts payable with respect to the loan and to enforce the Fund’s rights under the loan and other direct indebtedness, an insolvency, bankruptcy, or reorganization of the lending institution may delay or prevent the Fund from receiving such amounts. The highly leveraged nature of many loans may make them especially vulnerable to adverse changes in economic or market conditions. Investments in such loans and other direct indebtedness may involve additional risk to the Fund. There were no unfunded loan commitments at the six months ended January 31, 2024.

8. Credit and Market Risks (continued)

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, which may exceed amounts disclosed on the “Statement of assets and liabilities”, 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).

The Fund may invest up to 15% of its net assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A promulgated under the Securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair the Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. While maintaining oversight, the Board has delegated to DMC the day-to-day functions of determining whether individual securities are liquid for purposes of the Fund’s limitation on investments in illiquid securities. Securities eligible for resale pursuant to Rule 144A, which are determined to be liquid, are not subject to the Fund’s 15% limit on investments in illiquid securities. Rule 144A securities have been identified on the “Schedule of investments.”

9. Contractual Obligations

The Fund enters into contracts in the normal course of business that contain a variety of indemnifications. The Fund’s maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts. Management has reviewed the Fund’s existing contracts and expects the risk of loss to be remote.

10. Subsequent Events

Management has determined that no material events or transactions occurred subsequent to January 31, 2024, that would require recognition or disclosure in the Fund’s financial statements.

Board Consideration of Investment Management Agreement and Sub-Advisory Agreements at a Meeting Held on August 8-10, 2023

At a meeting held on August 8-10, 2023 (the “Annual Contract Renewal Meeting”), the Board of Trustees (the “Board”), including a majority of Trustees each of whom is not an “interested person” as defined under the Investment Company Act of 1940 (the “Independent Trustees”), approved the renewal of the Delaware Floating Rate Fund (the “Fund”) Investment Management Agreement with Delaware Management Company (“DMC”) and the Sub-Advisory Agreements with Macquarie Investment Management Global Limited (“MIMGL”), Macquarie Investment Management Austria Kapitalanlage AG (“MIMAK”) and Macquarie Investment Management Europe Limited (“MIMEL”) (together, the “Affiliated Sub-Advisers”).

In providing information to the Board, DMC was guided by a detailed set of requests for information submitted to them by independent legal counsel on behalf of the Independent Trustees at the start of the Board’s annual contract renewal process earlier in 2023. Prior to the Annual Contract Renewal Meeting, and in response to the requests, the Board received and reviewed materials specifically relating to the renewal of the Investment Management Agreement and the Sub-Advisory Agreements. In considering and approving the Investment Management Agreement and the Sub-Advisory Agreements, the Trustees considered the information they believed relevant, including but not limited to the information discussed below. The Board considered not only the specific information presented in connection with the Annual Contract Renewal Meeting and the review process for the Investment Management Agreement and the Sub-Advisory Agreements, but also the knowledge gained over time through interaction with DMC about various topics. In this regard, the Board reviewed reports of DMC at each of its quarterly meetings, which included information about, among other things, Fund performance, investment strategies, and expenses. In addition, the Investment Committees confer with portfolio managers at various times throughout the year. In considering information relating to the approval of the Fund’s Investment Management Agreement and the Sub-Advisory Agreements, the Independent Trustees also received information from an independent fund consultant, JDL Consultants, LLC (“JDL”).

The Board did not identify any particular information or consideration that was all-important or controlling, and each individual Trustee may have attributed different weights to various factors.

After its deliberations, the Board, including the Independent Trustees, unanimously approved the continuation of the Investment Management Agreement and the Sub-Advisory Agreements for a

one-year term. The following summarizes a number of important, but not necessarily all, factors considered by the Board in support of its approval.

Nature, extent, and quality of services. The Board received and considered various information regarding the nature, extent, and quality of the advisory services provided to the Fund by DMC under its Investment Management Agreement and the experience of the officers and employees of DMC who provide these services, including the Fund’s portfolio managers. The Board’s review included consideration of DMC’s investment process and oversight and research and analysis capabilities, and its ability to attract and retain skilled investment professionals. The Board also considered information regarding DMC’s programs for risk management, including investment, operational, liquidity, derivatives (as applicable), valuation, and compliance risks. The Board received information with respect to the cybersecurity program and business continuity plans of DMC and its affiliates.

In addition, the Board considered certain non-advisory services that DMC and its affiliates provide to the Delaware Funds by Macquarie complex (the “Delaware Funds”). Among other things, these services include third party service provider oversight, transfer agency, internal audit, valuation, portfolio trading, and legal and compliance functions. The Board noted DMC’s responsibility for overseeing the preparation of the Delaware Funds’ registration statement and supplements thereto and shareholder reports; responsibility for periodic filings with regulators; organizing Board meetings and preparing materials for such Board meetings; and furnishing analytical and other support to assist the Board. The Board took into account the benefits to shareholders of investing in a Fund that is part of a family of funds managed by an affiliate of Macquarie Group Ltd. (“Macquarie”), the parent company of DMC, and the resources available to DMC as part of Macquarie’s global asset management business.

The Board received and considered various information with respect to the services provided by the Affiliated Sub-Advisers under the Sub-Advisory Agreements and the credentials and experience of the officers and employees of the Affiliated Sub-Advisers who provide these services. The Board considered the division of responsibilities between DMC and the Affiliated Sub-Advisers, and the oversight provided by DMC. The Board also considered the expertise of the Affiliated Sub-Advisers with respect to certain asset classes and/or investment styles. The Board noted that the Affiliated Sub-Advisers are part of Macquarie’s global investment platform that has offices and personnel that are located around the world. These Affiliated Sub-Advisers provide research, investment and trading analysis on the markets and economies of various countries in which the Fund may invest, make recommendations regarding securities, provide portfolio management services and assist with security trades, as applicable. The Board took into account that the Sub-Advisory Agreements may benefit the Fund and its shareholders by permitting DMC to use the resources and talents of the Affiliated Sub-Advisers in managing the Fund.

The Board also received and considered information about the nature and extent of services offered and fee rates charged by DMC to other types of clients with investment strategies similar

to those of the Fund. In this regard, the Board received information about the significantly greater scope of services, and compliance, reporting and other legal and regulatory obligations and risks of managing registered investment companies compared with those associated with managing assets of other types of clients, including third-party sub-advised fund clients, unregistered funds and separately managed accounts.

The Board concluded that, overall, it was satisfied with the nature, extent, and quality of services provided (and expected to be provided) to the Fund by DMC and the Affiliated Sub-Advisers.

Investment performance. The Board received and considered information with respect to the investment performance of the Fund, including performance reports and discussions with portfolio managers at meetings of the Board’s Investment Committees throughout the year as well as reports provided by Broadridge Financial Solutions, Inc., an independent investment company data provider (“Broadridge”), furnished for the Annual Contract Renewal Meeting. The Broadridge reports prepared for the Fund’s institutional share class showed its investment performance in comparison to the institutional share class of a group of similar funds (the “Performance Universe”). The Board received a description of the methodology used by Broadridge to select the peer funds in the Performance Universe. Comparative annualized performance for the Fund was shown for the past 1-, 3-, 5-, and 10-year or since inception periods, as applicable, ended December 31, 2022.

The Performance Universe for the Fund consisted of the Fund and all retail and institutional loan participation funds, regardless of asset size or primary channel of distribution. The Board noted that the Broadridge report comparison showed that the Fund’s total return for the 1-, 3-, and 5-year periods was in the first quartile of its Performance Universe and for the 10-year period was in the third quartile of its Performance Universe. The Broadridge report comparison showed that the Fund’s total return for the 1-, 3-, and 5-year periods was above the median of its Performance Universe and for the 10-year period was below the median of its Performance Universe. The Board also noted that the Fund outperformed its benchmark index for the 5-year period and underperformed its benchmark index for the 1-, 3-, and 10-year periods. The Board noted that the Fund was generally performing in line with its Performance Universe during the periods under review. The Board noted the explanations from DMC and from the Affiliated Sub-Advisers concerning the reasons for the Fund’s relative performance versus its benchmark index for the various periods.

Comparative expenses. The Board received and considered expense data for the Fund. DMC provided the Board with information on pricing levels and fee structures for the Fund as of its most recently completed fiscal year. The Broadridge total expenses, for comparative consistency, were shown by Broadridge for Institutional Class shares and comparative total expenses including 12b-1 and non-12b-1 service fees. The Board also considered the comparative analysis of contractual management fees and actual total expense ratios of the Fund versus contractual management fees and actual total expense ratios of a group of peer funds as selected by Broadridge (the “Expense Group”). In reviewing comparative costs, the Fund’s contractual management fee and the actual management fee incurred by the Fund were compared with the contractual management fees (assuming all funds in the Expense Group were similar in size to the Fund) and actual management fees, taking into account any applicable breakpoints and fee

waivers, with the Fund’s expense universe, which is comprised of the Fund, its Expense Group and all other similar institutional funds, excluding outliers (the “Expense Universe”). The Fund’s total expenses were also compared with those of its Expense Universe. The Board also received and considered information regarding the Fund’s net operating expense ratios and their various components, including actual management fees, custodian and other non-management fees, and Rule 12b-1 and non-Rule 12b-1 shareholder service fees.

The expense comparisons for the Fund showed that its actual management fee was below the median of its Expense Universe and its actual total expenses were below its Expense Group average. It was noted that consistent with DMC’s waiver methodology, its advisory fee waivers, if any, were at the fund level and not class level.

The Board noted that DMC, and not the Fund, pays the sub-advisory fees to the Affiliated Sub-Advisers and, accordingly, that the retention of the Affiliated Sub-Advisers does not increase the fees and expenses incurred by the Fund.

Economies of scale. The Board received and considered information about the potential for DMC to realize economies of scale in the provision of management services to the Fund, the difficulties of calculating economies of scale at an individual Fund level, and the extent to which potential scale benefits are shared with shareholders, including the extent to which any economies of scale are reflected in the level of management fees charged. DMC discussed its advisory fee pricing and structure for the Delaware Funds, including the current breakpoints. The Board noted that, as of March 31, 2023, the Fund’s net assets exceeded its first breakpoint level and that breakpoints result in a lower advisory fee than would otherwise be the case in the absence of breakpoints, when the asset levels specified in the breakpoints schedule are exceeded. The Board noted that the Fund may also benefit from economies of scale through initial fee setting, fee waivers and expense reimbursements, as well as DMC’s investment in its business, including investments in business infrastructure, technology and cybersecurity.

Management profitability. The Board received and considered the Investment Management Profitability Analysis that addressed the overall profitability of DMC’s business in providing management and other services to the Fund and the Delaware Funds as a whole, including the methodology used by DMC in allocating costs for the purpose of determining profitability. The Board noted DMC’s changes to its cost allocation methodology for its profitability analysis and the explanations for such changes. The Board also reviewed a report prepared by JDL regarding DMC’s profitability as compared to certain peer fund complexes and the Independent Trustees discussed DMC’s profitability in such context with representatives from JDL. The Board recognized that calculating and comparing profitability at the individual fund level is difficult; that

Table of Contents

DMC’s profit, if any, can vary significantly depending on the particular fund; and that DMC’s support for, and commitment to, a fund is not solely dependent on the profits realized as to that fund.

Based on its review, the Board determined that DMC’s profitability was not excessive in light of the nature, extent and quality of the services provided to the Fund.

Based on its consideration of the factors and information it deemed relevant, including the costs of providing investment management and other services to the Fund and the ongoing commitment of DMC and its affiliates to the Fund, the Board did not find that any ancillary benefits received by DMC and its affiliates, including the Affiliated Sub-Advisers, were unreasonable.

Disclosure of Fund expenses

For the six-month period from August 1, 2023 to January 31, 2024 (Unaudited)

The investment objective of the Fund is to seek total return and, as a secondary objective, high current income.

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments, reinvested dividends, or other distributions; redemption fees; and exchange fees; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire six-month period from August 1, 2023 to January 31, 2024.

Actual expenses

Hypothetical example for comparison purposes

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. The Fund's expenses shown in the table reflect fee waivers in effect and assume reinvestment of all dividends and distributions.

Delaware High-Yield Opportunities Fund

January 31, 2024 (Unaudited)

Delaware Group^®Income Funds (Trust) is organized as a Delaware statutory trust and offers four series: Delaware Corporate Bond Fund, Delaware Extended Duration Bond Fund, Delaware Floating Rate Fund, and Delaware High-Yield Opportunities Fund. These financial statements and the related notes pertain to Delaware High-Yield Opportunities Fund (Fund). The Trust is an open-end investment company. The Fund is considered diversified under the Investment Company Act of 1940, as amended (1940 Act), and offers Class A, Class C, Class R, Institutional Class, and Class R6 shares. Class A shares are sold with a maximum front-end sales charge of 4.50%. There is no front-end sales charge when you purchase $1 million or more of Class A shares. However, if Delaware Distributors, L.P. (DDLP) paid your financial intermediary a commission on your purchase of $1 million or more of Class A shares, you will have to pay a limited contingent deferred sales charge (Limited CDSC) of 1.00% if you redeem these shares within the first 18 months after your purchase, unless a specific waiver of the Limited CDSC applies. Class C shares have no upfront sales charge, but are sold with a contingent deferred sales charge (CDSC) of 1.00%, which will be incurred if redeemed during the first 12 months. Class R, Institutional Class, and Class R6 shares are not subject to a sales charge and are offered for sale exclusively to certain eligible investors. In addition, Class R6 shares do not pay any service fees, sub-accounting fees, and/or sub-transfer agency fees to any brokers, dealers, or other financial intermediaries.

1. Significant Accounting Policies

Security Valuation — Equity securities and exchange-traded funds (ETFs), except those traded on the Nasdaq Stock Market LLC (Nasdaq), are valued at the last quoted sales price as of the time of the regular close of the New York Stock Exchange on the valuation date. Equity securities and ETFs traded on the Nasdaq are valued in accordance with the Nasdaq Official Closing Price, which may not be the last sales price. If, on a particular day, an equity security or ETF does not trade, the mean between the bid and the ask prices will be used, which approximates fair value. Fixed income securities are generally priced based upon valuations provided by an independent pricing service or broker in accordance with methodologies included within Delaware Management Company (DMC)’s Pricing Policy (the Policy). Fixed income security valuations are then reviewed by DMC as part of its duties as the Fund’s valuation designee and, to the extent required by the Policy and applicable regulation, fair valued consistent with the Policy. To the extent current market prices are not available, the pricing service may take into account developments related to the specific security, as well as transactions in comparable securities. Open-end investment companies, other than ETFs, are valued at their published net asset value (NAV). Forward foreign currency exchange contracts are valued at the mean between the bid and the ask prices, which approximates fair value. Interpolated values are derived when the settlement date of the contract is an interim date for

which quotations are not available. Valuations for fixed income securities utilize matrix systems, which reflect such factors as security prices, yields, maturities, and ratings, and are supplemented by dealer and exchange quotations. Generally, other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by DMC. Subject to the oversight of the Trust's Board of Trustees (Board), DMC, as valuation designee, has adopted policies and procedures to fair value securities for which market quotations are not readily available consistent with the requirements of Rule 2a-5 under the 1940 Act. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures or suspension of trading in a security. Restricted securities and private placements are valued at fair value.

Foreign Currency Transactions — Transactions denominated in foreign currencies are recorded at the prevailing exchange rates on the valuation date. The value of all assets and liabilities denominated in foreign currencies is translated daily into US dollars at the exchange rate of such currencies against the US dollar. Transaction gains or losses resulting from changes in exchange rates during the reporting period or upon settlement of the foreign currency transaction are reported in operations for the current period. The Fund generally bifurcates that portion of realized gains and losses on investments in debt securities which is due to changes in foreign exchange rates from that which is due to changes in market prices of debt securities. That portion of realized gains (losses), attributable to changes in foreign exchange rates, is included on the “Statement of operations” under “Net realized gain (loss) on foreign currencies.”

respectively, over the lives of the respective securities using the effective interest method. Premiums on callable debt securities are amortized to interest income to the earliest call date using the effective interest method. The Fund declares dividends daily from net investment income and pays the dividends monthly and declares and pays distributions from net realized gain on investments, if any, at least annually. The Fund may distribute more frequently, if necessary for tax purposes. Dividends and distributions, if any, are recorded on the ex-dividend date.

2. Investment Management, Administration Agreements, and Other Transactions with Affiliates

In accordance with the terms of its investment management agreement, the Fund pays DMC, a series of Macquarie Investment Management Business Trust and the investment manager, an annual fee which is calculated daily and paid monthly at the rates of 0.65% on the first $500 million of average daily net assets of the Fund, 0.60% on the next $500 million, 0.55% on the next $1.5 billion, and 0.50% on average daily net assets in excess of $2.5 billion.

DMC has contractually agreed to waive all or a portion of its investment advisory fees and/or pay/reimburse expenses (excluding any distribution and service (12b-1) fees, acquired fund fees and expenses, taxes, interest, short sale dividend and interest expenses, brokerage fees, certain insurance costs, and nonroutine expenses or costs, including, but not limited to, those relating to reorganizations, litigation, conducting shareholder meetings, and liquidations), in order to prevent total annual fund operating expenses from exceeding 0.63% of the Fund’s Class A, Class C, Class R, and Institutional Class shares' average daily net assets and 0.58% of the Fund’s Class R6 shares' average daily net assets from August 1, 2023 through November 29, 2024. These waivers and reimbursements may only be terminated by agreement of DMC and the Fund. The waivers and reimbursements are accrued daily and received monthly.

Advisors”). DMC may also permit these Affiliated Sub-Advisors to execute Fund security trades on its behalf and exercise investment discretion for securities in certain markets where DMC believes it will be beneficial to utilize an Affiliated Sub-Advisor’s specialized market knowledge. Although the Affiliated Sub-Advisors serve as sub-advisors, DMC has ultimate responsibility for all investment advisory services. For these services, DMC, not the Fund, pays each Affiliated Sub-Advisor a portion of its investment management fee.

Delaware Investments Fund Services Company (DIFSC), an affiliate of DMC, provides fund accounting and financial administrative oversight services to the Fund. For these services, effective October 1, 2023, DIFSC’s fees are calculated daily and paid monthly, based on the aggregate daily net assets of all funds within the Delaware Funds at the following annual rates: 0.0050% of the first $60 billion; 0.00475% of the next $30 billion; and 0.0015% of aggregate average daily net assets in excess of $90 billion (Total Fee). Prior to October 1, 2023, DIFSC's annual rates were: 0.00475% of the first $35 billion; 0.0040% of the next $10 billion; 0.0025% of the next $45 billion; and 0.0015% of aggregate average daily net assets in excess of $90 billion. Each fund in the Delaware Funds pays a minimum of $4,000, which, in aggregate, is subtracted from the Total Fee. Each fund then pays its portion of the remainder of the Total Fee on a relative NAV basis. This amount is included on the “Statement of operations” under “Accounting and administration expenses.” For the six months ended January 31, 2024, the Fund paid $10,669 for these services.

DIFSC is also the transfer agent and dividend disbursing agent of the Fund. For these services, DIFSC’s fees are calculated daily and paid monthly, based on the aggregate daily net assets of the retail funds within the Delaware Funds at the following annual rates: 0.014% of the first $20 billion; 0.011% of the next $5 billion; 0.007% of the next $5 billion; 0.004% of the next $20 billion; 0.002% of the next $25 billion; and 0.0015% of average daily net assets in excess of $75 billion. The fees payable to DIFSC under the shareholder services agreement described above are allocated among all retail funds in the Delaware Funds on a relative NAV basis. This amount is included on the “Statement of operations” under “Dividend disbursing and transfer agent fees and expenses.” For the six months ended January 31, 2024, the Fund paid $15,248 for these services. Pursuant to a sub-transfer agency agreement between DIFSC and BNY Mellon Investment Servicing (US) Inc. (BNYMIS), BNYMIS provides certain sub-transfer agency services to the Fund. Sub-transfer agency fees are paid by the Fund and are also included on the “Statement of operations” under “Dividend disbursing and transfer agent fees and expenses.” The fees are calculated daily and paid as invoices are received on a monthly or quarterly basis.

Pursuant to a distribution agreement and distribution plan, the Fund pays DDLP, the distributor and an affiliate of DMC, an annual 12b-1 fee of 0.25%, 1.00%, and 0.50% of the average daily net assets of the Class A, Class C, and Class R shares, respectively. The Board has adopted a formula for calculating 12b-1 fees for the Fund’s Class A shares that went into effect on June 1, 1992. The Fund’s Class A shares are subject to a blended 12b-1 fee of 0.10% on all

Table of Contents

shares acquired prior to June 1, 1992, and 0.25% on all shares acquired on or after June 1, 1992. All Class A shareholders currently bear 12b-1 fees at the same rate, the blended rate, currently 0.25% of the average daily net assets, based on the formula described above. This method of calculating Class A 12b-1 fees may be discontinued at the sole discretion of the Board. The fees are calculated daily and paid monthly. Institutional Class and Class R6 shares do not pay 12b-1 fees.

As provided in the investment management agreement, the Fund bears a portion of the cost of certain resources shared with DMC, including the cost of internal personnel of DMC and/or its affiliates that provide legal and regulatory reporting services to the Fund. For the six months ended January 31, 2024, the Fund paid $5,993 for internal legal and regulatory reporting services provided by DMC and/or its affiliates’ employees. This amount is included on the “Statement of operations” under “Legal fees.”

For the six months ended January 31, 2024, DDLP earned $3,460 for commissions on sales of the Fund’s Class A shares. For the six months ended January 31, 2024, DDLP received gross CDSC commissions of $2 and $72 on redemptions of the Fund’s Class A and Class C shares, respectively, and these commissions were entirely used to offset upfront commissions previously paid by DDLP to broker/dealers on sales of those shares.

7. Securities Lending

Cash collateral received by the Fund is generally invested in an individual separate account. The investment guidelines permit each separate account to hold certain securities that would be

Table of Contents

considered eligible securities for a money market fund. Cash collateral received is generally invested in government securities; certain obligations issued by government sponsored enterprises; repurchase agreements collateralized by US Treasury securities; obligations issued by the central government of any Organization for Economic Cooperation and Development (OECD) country or its agencies, instrumentalities, or establishments; obligations of supranational organizations; commercial paper, notes, bonds, and other debt obligations; certificates of deposit, time deposits, and other bank obligations; certain money market funds; and asset-backed securities. The Fund can also accept US government securities and letters of credit (non-cash collateral) in connection with securities loans.

In the event of default or bankruptcy by the lending agent, realization and/or retention of the collateral may be subject to legal proceedings. In the event the borrower fails to return loaned securities and the collateral received is insufficient to cover the value of the loaned securities and provided such collateral shortfall is not the result of investment losses, the lending agent has agreed to pay the amount of the shortfall to the Fund or, at the discretion of the lending agent, replace the loaned securities. The Fund continues to record dividends or interest, as applicable, on the securities loaned and is subject to changes in value of the securities loaned that may occur during the term of the loan. The Fund has the right under the Lending Agreement to recover the securities from the borrower on demand. With respect to security loans collateralized by non-cash collateral, the Fund receives loan premiums paid by the borrower. With respect to security loans collateralized by cash collateral, the earnings from the collateral investments are shared among the Fund, the security lending agent, and the borrower. The Fund records security lending income net of allocations to the security lending agent and the borrower.

At January 31, 2024, the Fund had no securities out on loan.

market conditions. Investments in such loans and other direct indebtedness may involve additional risk to the Fund. There were no unfunded loan commitments at the six months ended January 31, 2024.

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, which may exceed amounts disclosed on the “Statement of assets and liabilities”, 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).

9. Contractual Obligations

The Fund enters into contracts in the normal course of business that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts. Management has reviewed the Fund's existing contracts and expects the risk of loss to be remote.

10. Subsequent Events

On January 16, 2024, the Board approved the reorganization of the Fund into and with a substantially similar fund and class of another Delaware Fund (the “Reorganization”) as shown in the table below:

Acquired Fund	Acquiring Fund
Delaware High-Yield Opportunities Fund, a series of the Trust	Delaware Ivy High Income Fund, a series of Ivy Funds

The Reorganization is subject to the approval of Fund shareholders at a special shareholder meeting anticipated to be held on March 25, 2024. If the Reorganization is approved by

shareholders at that March 25, 2024 special shareholder meeting, the Reorganization is expected to occur on or about April 26, 2024.

Board Consideration of Investment Management Agreement and Sub-Advisory Agreements at a Meeting Held on August 8-10, 2023

At a meeting held on August 8-10, 2023 (the “Annual Contract Renewal Meeting”), the Board of Trustees (the “Board”), including a majority of Trustees each of whom is not an “interested person” as defined under the Investment Company Act of 1940 (the “Independent Trustees”), approved the renewal of the Delaware High-Yield Opportunities Fund (the “Fund”) Investment Management Agreement with Delaware Management Company (“DMC”) and the Sub-Advisory Agreements with Macquarie Investment Management Global Limited (“MIMGL”), Macquarie Investment Management Austria Kapitalanlage AG (“MIMAK”) and Macquarie Investment Management Europe Limited (“MIMEL”) (together, the “Affiliated Sub-Advisers”).

In providing information to the Board, DMC was guided by a detailed set of requests for information submitted to them by independent legal counsel on behalf of the Independent Trustees at the start of the Board’s annual contract renewal process earlier in 2023. Prior to the Annual Contract Renewal Meeting, and in response to the requests, the Board received and reviewed materials specifically relating to the renewal of the Investment Management Agreement and the Sub-Advisory Agreements. In considering and approving the Investment Management Agreement and the Sub-Advisory Agreements, the Trustees considered the information they believed relevant, including but not limited to the information discussed below. The Board considered not only the specific information presented in connection with the Annual Contract Renewal Meeting and the review process for the Investment Management Agreement and the Sub-Advisory Agreements, but also the knowledge gained over time through interaction with DMC about various topics. In this regard, the Board reviewed reports of DMC at each of its quarterly meetings, which included information about, among other things, Fund performance, investment strategies, and expenses. In addition, the Investment Committees confer with portfolio managers at various times throughout the year. In considering information relating to the approval of the Fund’s Investment Management Agreement and the Sub-Advisory Agreements, the Independent Trustees also received information from an independent fund consultant, JDL Consultants, LLC (“JDL”).

The Board did not identify any particular information or consideration that was all-important or controlling, and each individual Trustee may have attributed different weights to various factors.

After its deliberations, the Board, including the Independent Trustees, unanimously approved the continuation of the Investment Management Agreement and the Sub-Advisory Agreements for a

Delaware High-Yield Opportunities Fund

Board Consideration of Investment Management Agreement and Sub-Advisory Agreements at a Meeting Held on August 8-10, 2023 (continued)

one-year term. The following summarizes a number of important, but not necessarily all, factors considered by the Board in support of its approval.

Nature, extent, and quality of services. The Board received and considered various information regarding the nature, extent, and quality of the advisory services provided to the Fund by DMC under its Investment Management Agreement and the experience of the officers and employees of DMC who provide these services, including the Fund’s portfolio managers. The Board’s review included consideration of DMC’s investment process and oversight and research and analysis capabilities, and its ability to attract and retain skilled investment professionals. The Board also considered information regarding DMC’s programs for risk management, including investment, operational, liquidity, derivatives (as applicable), valuation, and compliance risks. The Board received information with respect to the cybersecurity program and business continuity plans of DMC and its affiliates.

In addition, the Board considered certain non-advisory services that DMC and its affiliates provide to the Delaware Funds by Macquarie complex (the “Delaware Funds”). Among other things, these services include third party service provider oversight, transfer agency, internal audit, valuation, portfolio trading, and legal and compliance functions. The Board noted DMC’s responsibility for overseeing the preparation of the Delaware Funds’ registration statement and supplements thereto and shareholder reports; responsibility for periodic filings with regulators; organizing Board meetings and preparing materials for such Board meetings; and furnishing analytical and other support to assist the Board. The Board took into account the benefits to shareholders of investing in a Fund that is part of a family of funds managed by an affiliate of Macquarie Group Ltd. (“Macquarie”), the parent company of DMC, and the resources available to DMC as part of Macquarie’s global asset management business.

The Board received and considered various information with respect to the services provided by the Affiliated Sub-Advisers under the Sub-Advisory Agreements and the credentials and experience of the officers and employees of the Affiliated Sub-Advisers who provide these services. The Board considered the division of responsibilities between DMC and the Affiliated Sub-Advisers and the oversight provided by DMC. The Board also considered the expertise of the Affiliated Sub-Advisers with respect to certain asset classes and/or investment styles. The Board noted that the Affiliated Sub-Advisers are part of Macquarie’s global investment platform that has offices and personnel that are located around the world. These Affiliated Sub-Advisers provide research, investment and trading analysis on the markets and economies of various countries in which the Fund may invest, make recommendations regarding securities, provide portfolio management services and assist with security trades, as applicable. The Board took into account that the Sub-Advisory Agreements may benefit the Fund and its shareholders by permitting DMC to use the resources and talents of the Affiliated Sub-Advisers in managing the Fund.

The Board also received and considered information about the nature and extent of services offered and fee rates charged by DMC to other types of clients with investment strategies similar

Table of Contents

The Board concluded that, overall, it was satisfied with the nature, extent, and quality of services provided (and expected to be provided) to the Fund by DMC and the Affiliated Sub-Advisers.

Investment performance. The Board received and considered information with respect to the investment performance of the Fund, including performance reports and discussions with portfolio managers at meetings of the Board’s Investment Committees throughout the year as well as reports provided by Broadridge Financial Solutions, Inc., an independent investment company data provider (“Broadridge”), furnished for the Annual Contract Renewal Meeting. The Broadridge reports prepared for the Fund’s institutional share class showed its investment performance in comparison to the institutional share class of a group of similar funds (the “Performance Universe”). The Board received a description of the methodology used by Broadridge to select the peer funds in the Performance Universe. Comparative annualized performance for the Fund was shown for the past 1-, 3-, 5-, and 10-year or since inception periods, as applicable, ended December 31, 2022.

The Performance Universe for the Fund consisted of the Fund and all retail and institutional high yield funds, regardless of asset size or primary channel of distribution. The Board noted that the Broadridge report comparison showed that the Fund’s total return for the 1-, 3-, and 10-year periods was in the second quartile of its Performance Universe and for the 5-year period was in the first quartile of its Performance Universe. The Broadridge report comparison showed that the Fund’s total return for the 1-, 3-, 5-, and 10-year periods was above the median of its Performance Universe. The Board also noted that the Fund outperformed its benchmark index for the 1-, 3-, and 5-year periods and underperformed its benchmark index for the 10-year period. The Board noted that the Fund was generally performing in line with its Performance Universe and benchmark during the periods under review.

Comparative expenses. The Board received and considered expense data for the Fund. DMC provided the Board with information on pricing levels and fee structures for the Fund as of its most recently completed fiscal year. The Broadridge total expenses, for comparative consistency, were shown by Broadridge for Institutional Class shares and comparative total expenses including 12b-1 and non-12b-1 service fees. The Board also considered the comparative analysis of contractual management fees and actual total expense ratios of the Fund versus contractual management fees and actual total expense ratios of a group of peer funds as selected by Broadridge (the “Expense Group”). In reviewing comparative costs, the Fund’s contractual management fee and the actual management fee incurred by the Fund were compared with the contractual management fees (assuming all funds in the Expense Group were similar in size to the Fund) and actual management fees, taking into account any applicable breakpoints and fee waivers, with the Fund’s expense universe, which is comprised of the Fund, its Expense Group and all other similar institutional funds, excluding outliers (the “Expense Universe”). The Fund’s total expenses were also compared with those of its Expense Universe. The Board also received

Table of Contents

Other Fund information (Unaudited)

Delaware High-Yield Opportunities Fund

Board Consideration of Investment Management Agreement and Sub-Advisory Agreements at a Meeting Held on August 8-10, 2023 (continued)

and considered information regarding the Fund’s net operating expense ratios and their various components, including actual management fees, custodian and other non-management fees, and Rule 12b-1 and non-Rule 12b-1 shareholder service fees.

Economies of scale. The Board received and considered information about the potential for DMC to realize economies of scale in the provision of management services to the Fund, the difficulties of calculating economies of scale at an individual Fund level, and the extent to which potential scale benefits are shared with shareholders, including the extent to which any economies of scale are reflected in the level of management fees charged. DMC discussed its advisory fee pricing and structure for the Delaware Funds, including the current breakpoints. The Board noted that the Fund may also benefit from economies of scale through initial fee setting, fee waivers and expense reimbursements, as well as DMC’s investment in its business, including investments in business infrastructure, technology and cybersecurity.

Management profitability. The Board received and considered the Investment Management Profitability Analysis that addressed the overall profitability of DMC’s business in providing management and other services to the Fund and the Delaware Funds as a whole, including the methodology used by DMC in allocating costs for the purpose of determining profitability. The Board noted DMC’s changes to its cost allocation methodology for its profitability analysis and the explanations for such changes. The Board also reviewed a report prepared by JDL regarding DMC’s profitability as compared to certain peer fund complexes and the Independent Trustees discussed DMC’s profitability in such context with representatives from JDL. The Board recognized that calculating and comparing profitability at the individual fund level is difficult; that DMC’s profit, if any, can vary significantly depending on the particular fund; and that DMC’s support for, and commitment to, a fund is not solely dependent on the profits realized as to that fund.

Table of Contents

evaluated information about the nature and extent of the responsibilities retained and risk assumed by DMC and not delegated to or assumed by the Affiliated Sub-Advisers. Given the affiliation between DMC and the Affiliated Sub-Advisers, the Board ascribed limited relevance to the allocation of fees between them.

Based on its review, the Board determined that DMC’s profitability was not excessive in light of the nature, extent, and quality of the services provided to the Fund.

Ancillary benefits. The Board received and considered information regarding the extent to which DMC and its affiliates might derive ancillary benefits from fund operations, including the potential for procuring additional business as a result of the prestige and visibility associated with its role as investment manager to the Delaware Funds; the benefits from allocation of fund brokerage to improve trading efficiencies; the portfolio transactions executed through “soft dollar” arrangements; and the fees that various affiliates received for serving as transfer agent and for overseeing fund accounting and financial administration services to the Delaware Funds. The Board considered that it receives periodic reports from DMC that include a representation that any soft dollar arrangements are consistent with regulatory requirements. The Board received information from DMC regarding its view of the performance of its affiliates in providing transfer agent and fund accounting and financial administration oversight services and the organizational structure employed to provide these services pursuant to their contracts with the Fund.

Conclusion. Based on its review, consideration and evaluation of all factors it believed relevant, including the above-described factors and conclusions, the Board, including all of the Independent Trustees, approved the continuation of DMC’s Investment Management Agreement and of the Affiliated Sub-Advisers’ Sub-Advisory Agreements for an additional one-year period.

The Fund files its complete schedule of portfolio holdings with the Securities and Exchange Commission (SEC) for the first and third quarters of each fiscal year on Form N-PORT.
