Disclosure of Fund expenses

For the six-month period from November 1, 2023 to April 30, 2024 (Unaudited)

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 November 1, 2023 to April 30, 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.

*“Expenses Paid During Period” are equal to the Fund’s annualized expense ratio, multiplied by the average account value over the period, multiplied by 182/366 (to reflect the one-half year period).

^†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 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.

¹	See Note 6 in “Notes to financial statements.”

A CDS contract is a risk-transfer instrument through which one party (purchaser of protection) transfers to another party (seller of protection) the financial risk of a credit event (as defined in the CDS agreement), as it relates to a particular reference security or basket of securities (such as an index). Periodic payments (receipts) on such contracts are accrued daily and recorded as unrealized losses (gains) on swap contracts. Upon payment (receipt), such amounts are recorded as realized losses (gains) on swap contracts. Upfront payments made or received in connection with CDS contracts are amortized over the expected life of the CDS contracts as unrealized losses (gains) on swap contracts. The change in value of CDS contracts is recorded daily as unrealized appreciation or depreciation. A realized gain or loss is recorded upon a credit event (as defined in the CDS agreement) or the maturity or termination of the CDS agreement.

³	Notional amount shown is stated in USD unless noted that the swap is denominated in another currency.

⁴	Unrealized appreciation (depreciation) does not include periodic interest payments (receipt) on swap contracts accrued daily in the amount of $(184,259).

⁵	Markit’s North America High Yield Index, or the CDX.NA.HY Index, is composed of 100 liquid North American entities with high yield credit ratings that trade in the CDS market.

Notes to financial statements

Delaware Diversified Income Fund

April 30, 2024 (Unaudited)

Delaware Group^®Adviser Funds (Trust) is organized as a Delaware statutory trust and offers one fund: Delaware Diversified Income 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

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 (NYSE) 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 and credit default swap (CDS) contracts are generally priced based upon valuations provided by an independent pricing service or broker/counterparty in accordance with methodologies included within Delaware Management Company (DMC)'s Pricing Policy (the Policy). Fixed income security valuations and CDS contracts 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. 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. For asset-backed securities, collateralized

Table of Contents

mortgage obligations (CMOs), commercial mortgage securities, and US government agency mortgage securities, pricing vendors utilize matrix pricing which considers prepayment speed, attributes of the collateral, yield or price of bonds of comparable quality, coupon, maturity, and type as well as broker/dealer-supplied prices. Swap prices are derived using daily swap curves and models that incorporate a number of market data factors, such as discounted cash flows, trades, and values of the underlying reference instruments. 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. Futures contracts and options on futures contracts are valued at the daily quoted settlement prices. Investments for which market quotations are not readily available are valued at fair value as determined in good faith pursuant to Rule 2a-5 under the Investment Company Act of 1940 (Rule 2a-5). As a general principle, the fair value of a security or other asset is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Pursuant to Rule 2a-5, the Board of Trustees (Board) has designated DMC as the valuation designee (Valuation Designee) for each fund to perform the fair value determination relating to all applicable Fund investments. DMC has established a Pricing Committee to assist with its designated responsibilities as Valuation Designee, and DMC may carry out its designated responsibilities as Valuation Designee through the Pricing Committee and other teams and committees, which operate under policies and procedures approved by the Board and subject to the Board’s oversight. Fair value pricing may be used more frequently for securities traded primarily in non-US markets. In considering whether fair valuation is required and in determining fair values, the Valuation Designee may, among other things, consider significant events (which may be considered to include changes in the value of U.S. securities or securities indexes) that occur after the close of the relevant market and before the close of the NYSE. The Valuation Designee may utilize modeling tools provided by third-party vendors to determine fair values of non-U.S. securities.

Federal and Foreign 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 April 30, 2024, and for all open tax years (years ended October 31, 2020–October 31, 2023), and has concluded that no provision for federal income tax is required in the Fund’s financial statements. In regard to foreign taxes only, the Fund has open tax years in certain foreign countries in which it invests that may date back to the inception of the Fund. If applicable, the Fund recognizes interest accrued on unrecognized tax benefits in interest expense and penalties

Notes to financial statements

Delaware Diversified Income Fund

1. Significant Accounting Policies (continued)

in “Other” on the “Statement of operations.” During the six months ended April 30, 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.

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.” 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

Table of Contents

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.”

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 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 investment companies (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. Realized gains (losses) on paydowns of asset- and mortgage-backed securities are classified as interest income. 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. Withholding taxes and reclaims on foreign interest have been recorded in accordance with the Fund’s understanding of the applicable country’s tax rules and rates. The Fund may pay foreign capital gains taxes on certain foreign securities held, which are reported as components of realized losses for financial reporting purposes, whereas such components are treated as ordinary loss for federal income tax purposes. The Fund will accrue such taxes as applicable based upon current interpretations of the tax rules and regulations that exist in the markets in which it invests. The Fund declares dividends daily from net investment income and pays the dividends monthly and declares and pays dividends 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 0.55% on the first $500 million of average daily net assets of the Fund, 0.50% on the next $500 million, 0.45% on the next $1.5 billion, 0.425% on the next $5.5 billion, and 0.40% on average daily net assets in excess of $8 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 0.45% of the Fund’s Class A, Class C, Class R, and Institutional Class shares’ average daily net assets and 0.36% of the Fund’s Class R6 shares’ average daily net assets from November 1, 2023 through February 26, 2025. 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.

After consideration of class specific expenses, including 12b-1 fees, the class level operating expense limitation as a percentage of average daily net assets from November 1, 2023 through February 26, 2025, unless terminated by agreement of DMC and the Fund, is as follows:

Operating expense limitation as a percentage of average daily net assets
Class A	Class C	Class R	Institutional Class	Class R6
0.70%	1.45%	0.95%	0.45%	0.36%

DMC has entered into Sub-Advisory Agreements on behalf of the Fund with Macquarie Investment Management Austria Kapitalanlage AG, Macquarie Investment Management Global Limited and Macquarie Investment Management Europe Limited, each of which is an affiliate of DMC (Affiliated Sub-Advisor). Pursuant to the terms of the relevant Sub-Advisory Agreement, the investment sub-advisory fee is paid by DMC to each Affiliated Sub-Advisor based on the extent to which an Affiliated Sub-Advisor provides services to the Fund. For these services, DMC, not the Fund, may pay the 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, 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;

Table of Contents

0.00475% of the next $30 billion; and 0.0015% of aggregate average daily net assets in excess of $90 billion (Total Fee). 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 April 30, 2024, the Fund paid $65,204 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 April 30, 2024, the Fund paid $93,193 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 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 April 30, 2024, the Fund paid $42,641 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 April 30, 2024, DDLP earned $11,225 for commissions on sales of the Fund’s Class A shares. For the six months ended April 30, 2024, DDLP received gross CDSC commissions of $110 and $925 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 April 30, 2024, the Fund made purchases and sales of investment securities other than short-term investments as follows:

Purchases other than US government securities	$	403,556,977
Purchases of US government securities		990,913,313
Sales other than US government securities		364,755,450
Sales of US government securities		724,515,113

At April 30, 2024, the cost and unrealized appreciation (depreciation) of investments and derivatives for federal income tax purposes have been estimated since final tax characteristics cannot be determined until fiscal year end. At April 30, 2024, the cost and unrealized appreciation (depreciation) of investments and derivatives for the Fund were as follows:

Cost of investments and derivatives	$	3,264,860,065
Aggregate unrealized appreciation of investments and derivatives	$	15,404,270
Aggregate unrealized depreciation of investments and derivatives		(288,247,394	)
Net unrealized depreciation of investments and derivatives	$	(272,843,124	)

For federal income tax purposes, capital loss carryforwards may be carried forward and applied against future capital gains. At October 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
$	153,109,504	$	252,489,462	$	405,598,966

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

Table of Contents

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 April 30, 2024:

¹Forward foreign currency exchange contracts, futures contracts and swap contracts are valued at the unrealized appreciation (depreciation) on the instrument at the period end.

During the six months ended April 30, 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), is a participant in a $335,000,000 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 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 Participants are permitted to borrow up to a maximum of one-third of their net assets under the Agreement. Each Participant is individually, and not jointly, liable for its particular advances, if any, under the line of credit. The line of credit available under the Agreement expires on October 28, 2024.

The Fund had no amounts outstanding as of April 30, 2024, or at any time during the period then ended.

6. 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.

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 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. Open forward foreign currency exchange contracts, if any, are disclosed on the “Schedule of investments.” At April 30, 2024, the Fund posted $900,000 and received $455,000 cash as collateral for open

Table of Contents

forward foreign currency exchange contracts, which is included in “Cash collateral due from brokers” and “Cash collateral due to brokers”, respectively on the “Statement of assets and liabilities.”

During the six months ended April 30, 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.

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. The Fund may use futures contracts in the normal course of pursuing its investment objective. The 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, the 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 market value of the contract. These receipts or payments are known as “variation margin” and are recorded daily by the Fund as unrealized gains or losses until the contracts are closed. When the contracts are closed, the Fund records 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 Fund because futures are exchange-traded and the exchange’s clearinghouse, as counterparty to all exchange-traded futures, guarantees against default. At April 30, 2024, the Fund posted $12,518,988 cash collateral as margin for open futures contracts, which is included in “Cash collateral due from brokers” on the “Statement of assets and liabilities.” Open futures contracts, if any, are disclosed on the “Schedule of investments.”

During the six months ended April 30, 2024, the Fund entered into futures contracts to hedge the Fund’s existing portfolio securities against fluctuations in value caused by changes in interest rates or market conditions.

Options Contracts — The Fund may enter into options contracts in the normal course of pursuing its investment objective. The Fund may buy or write options contracts for any number of reasons, including without limitation: to manage the Fund’s exposure to changes in securities prices caused by interest rates or market conditions and foreign currencies; as an efficient means of adjusting the Fund’s overall exposure to certain markets; to protect the value of portfolio securities; and as a cash management tool. The Fund may buy or write call or put options on securities, futures, swaps, swaptions, financial indices, and foreign currencies. When the Fund buys an option, a premium is paid and an asset is recorded and adjusted on a daily basis to reflect the current market value of the option purchased. When the Fund writes an

Table of Contents

Notes to financial statements

Delaware Diversified Income Fund

6. Derivatives (continued)

option, a premium is received and a liability is recorded and adjusted on a daily basis to reflect the current market value of the option written. Premiums received from writing options that expire unexercised are treated by the Fund on the expiration date as realized gains. The difference between the premium received and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is treated as realized gain or loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Fund has a realized gain or loss. If a put option is exercised, the premium reduces the cost basis of the securities purchased by the Fund. The Fund, as writer of an option, bears the market risk of an unfavorable change in the price of the security underlying the written option. When writing options, the Fund is subject to minimal counterparty risk because the counterparty is only obligated to pay premiums and does not bear the market risk of an unfavorable market change. No options contracts were outstanding at April 30, 2024.

During the six months ended April 30, 2024, the Fund used options contracts to manage the Fund’s exposure to changes in securities prices caused by interest rates or market conditions, to adjust the Fund’s overall exposure to certain markets, to receive premiums for writing options and to facilitate investments in portfolio securities.

Swap Contracts — The Fund may enter into CDS contracts in the normal course of pursuing its investment objective. The Fund may enter into CDS contracts in order to hedge against a credit event, to enhance total return or to gain exposure to certain securities or markets. The Fund will not be permitted to enter into any swap transactions unless, at the time of entering into such transactions, the unsecured long-term debt of the actual counterparty, combined with any credit enhancements, is rated at least BBB- by Standard & Poor’s Financial Services LLC (S&P) or Baa3 by Moody’s Investors Service, Inc. (Moody’s) or is determined to be of equivalent credit quality by DMC.

Credit Default Swaps. A CDS contract is a risk-transfer instrument through which one party (purchaser of protection) transfers to another party (seller of protection) the financial risk of a credit event (as defined in the CDS agreement), as it relates to a particular reference security or basket of securities (such as an index). In exchange for the protection offered by the seller of protection, the purchaser of protection agrees to pay the seller of protection a periodic amount at a stated rate that is applied to the notional amount of the CDS contract. In addition, an upfront payment may be made or received by the Fund in connection with an unwinding or assignment of a CDS contract. Upon the occurrence of a credit event, the seller of protection would pay the par (or other agreed-upon) value of the reference security (or basket of securities) to the counterparty. Credit events generally include, among others, bankruptcy, failure to pay, and obligation default.

During the six months ended April 30, 2024, the Fund entered into CDS contracts as a purchaser of protection, as a hedge against credit events. Periodic payments (receipts) on such contracts are accrued daily and recorded as unrealized losses (gains) on swap contracts. Upon payment (receipt), such amounts are recorded as realized losses (gains) on swap contracts. Upfront

Table of Contents

payments made or received in connection with CDS contracts are amortized over the expected life of the CDS contracts as unrealized losses (gains) on swap contracts. The change in value of CDS contracts is recorded daily as unrealized appreciation or depreciation. A realized gain or loss is recorded upon a credit event (as defined in the CDS agreement) or the maturity or termination of the agreement. Initial margin and variation margin are posted to central counterparties for centrally cleared CDS basket trades, as determined by the applicable central counterparty. During the six months ended April 30, 2024, the Fund did not enter into any CDS contracts as a seller of protection.

CDS contracts may involve greater risks than if the Fund had invested in the reference obligation directly. CDS contracts are subject to general market risk, liquidity risk, counterparty risk, and credit risk. The Fund’s maximum risk of loss from counterparty credit risk, either as the seller of protection or the buyer of protection, is the fair value of the contract. This risk is mitigated by (1) for bilateral swap contracts, 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, and (2) for cleared swaps, trading these instruments through a central counterparty.

During the six months ended April 30, 2024, the Fund entered into CDS contracts to hedge against credit events.

At April 30, 2024, the Fund posted $1,228,287 cash collateral for centrally cleared derivatives, which is included in “Cash collateral due from brokers” on the “Statement of assets and liabilities.”

Fair values of derivative instruments as of April 30, 2024 were as follows:

7. Offsetting

The Fund entered into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or a similar agreement with certain of its derivative contract counterparties in order to better define its contractual rights and to secure rights that will help the Fund mitigates its counterparty risk. An ISDA Master Agreement is a bilateral agreement between the Fund and a counterparty that governs certain over-the-counter derivatives and foreign exchange contracts and typically contains, among other things, collateral posting items and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out), including the bankruptcy or insolvency of the counterparty. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency, or other events.

For financial reporting purposes, the Fund does not offset derivative assets and derivative liabilities that are subject to netting arrangements on the “Statement of assets and liabilities.”

At April 30, 2024, the Fund had the following assets and liabilities subject to offsetting provisions:

^(a)Net exposure represents the receivable (payable) that would be due from (to) the counterparty in the event of default.

8. 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 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

Table of Contents

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 April 30, 2024, the 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.

Beginning in late February 2022, global financial markets have experienced and may continue to experience significant volatility related to military action by Russia in Ukraine. As a result of this military action, the US and many other countries have imposed sanctions on Russia and certain Russian individuals, banks and corporations. The ongoing hostilities and resulting sanctions are expected to have a severe adverse effect on the region’s economies and more globally, including significant negative impact on markets for certain securities and commodities, such as oil and natural gas. Any cessation of trading on the Russian securities markets will impact the value and liquidity of certain portfolio holdings. The extent and duration of military action, sanctions, and resulting market disruptions are impossible to predict, but could be substantial and prolonged and impact the Fund’s performance.

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

Table of Contents

Notes to financial statements

Delaware Diversified Income Fund

9. Credit and Market Risks (continued)

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.

The Fund invests in fixed income securities whose value is derived from an underlying pool of mortgages or consumer loans. The value of these securities is sensitive to changes in economic conditions, including delinquencies and/or defaults, and may be adversely affected by shifts in the market’s perception of the issuers and changes in interest rates. Investors receive principal and interest payments as the underlying mortgages and consumer loans are paid back. Some of these securities are CMOs. CMOs are debt securities issued by US government agencies or by financial institutions and other mortgage lenders, which are collateralized by a pool of mortgages held under an indenture. Prepayment of mortgages may shorten the stated maturity of the obligations and can result in a loss of premium, if any has been paid. Certain of these securities may be stripped (securities which provide only the principal or interest feature of the underlying security). The yield to maturity on an interest-only CMO is extremely sensitive not only to changes in prevailing interest rates, but also to the rate of principal payments (including prepayments) on the related underlying mortgage assets. A rapid rate of principal payments may have a material adverse effect on the Fund’s yield to maturity. If the underlying mortgage assets experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities even if the securities are rated in the highest rating categories.

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 the security.

The Fund invests a portion of its assets in high yield fixed income securities, which are securities rated lower than BBB- by S&P and Baa3 by Moody’s, 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.

Some countries in which the Fund may invest require governmental approval for the repatriation of investment income, capital, or the proceeds of sales of securities by foreign investors. In addition, if there is deterioration in a country’s balance of payments or for other reasons, a country may impose temporary restrictions on foreign capital remittances abroad.

The securities exchanges of certain foreign markets are substantially smaller, less liquid, and more volatile than the major securities markets in the US. Consequently, acquisition and disposition of securities by the Fund may be inhibited. In addition, a significant portion of the

Table of Contents

aggregate market value of securities listed on the major securities exchanges in emerging markets is held by a smaller number of investors. This may limit the number of shares available for acquisition or disposition by the Fund.

The Fund may invest in mortgage-backed and asset-backed securities. Mortgage-backed and asset-backed securities, like other fixed income securities, are subject to credit risk and interest rate risk, and may also be subject to prepayment risk and extension risk. Mortgage-backed and asset-backed securities can be highly sensitive to interest rate changes. As a result, small movements in interest rates can substantially impact the value and liquidity of these securities. Prepayment risk is the risk that the principal on mortgage-backed or asset-backed securities may be prepaid at any time, which will reduce the yield and market value of the securities and may cause the Fund to reinvest the proceeds in lower yielding securities. Extension risk is the risk that principal on mortgage-backed or asset-backed securities will be repaid more slowly than expected, which may reduce the proceeds available for reinvestment in higher yielding securities and may cause the security to experience greater volatility due to the extended maturity of the security. When interest rates rise, the value of mortgage-backed and asset-backed securities can be expected to decline. When interest rates go down, however, the value of these securities may not increase as much as other fixed income securities due to borrowers refinancing their loans at lower interest rates or prepaying their loans. In addition, mortgage-backed and asset-backed securities may decline in value, become more volatile, face difficulties in valuation, or experience reduced liquidity due to changes in general economic conditions. During periods of economic downturn, for example, underlying borrowers may not make timely payments on their loans and the value of property that secures the loans may decline in value such that it is worth less than the amount of the associated loans. If the collateral securing a mortgage-backed or asset-backed security is insufficient to repay the loan, the Fund could sustain a loss. Such risks generally will be heightened where a mortgage-backed or asset-backed security includes “subprime” loans. Although mortgage-backed securities are often supported by government guarantees or private insurance, there can be no guarantee that those obligations will be met. Furthermore, in certain economic conditions, loan servicers, loan originators and other participants in the market for mortgage-backed and other asset-backed securities may be unable to receive sufficient funding, impairing their ability to perform their obligations on the loans. Certain mortgage-backed or asset-backed securities may be more susceptible to these risks than other mortgage-backed, asset-backed, or fixed-income securities. For example, the Fund’s investments in CMOs, real estate mortgage investment conduits (REMICs), and stripped mortgage-backed securities are generally highly susceptible to interest rate risk, prepayment risk, and extension risk. At times, these investments may be difficult to value and/or illiquid. Some classes of CMOs and REMICs may have preference in receiving principal or interest payments relative to more junior classes. The market prices and yields of these junior classes will generally be more volatile than more senior classes and will be more susceptible to interest rate risk, prepayment risk, and extension risk than more senior classes. Stripped mortgage-backed securities that receive only payments of interest (IOs) will generally decrease in value if interest rates decline or prepayment rates increase. Stripped mortgage-backed securities that receive only payments of principal (POs) will generally decrease in value if interest rates increase or prepayment rates decrease. These

9. Credit and Market Risks (continued)

changes in value can be substantial and could cause the Fund to lose the entire value of its investment in CMOs, REMICs, and stripped mortgage-backed securities.

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.

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 April 30, 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).

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

Table of Contents

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.”

10. 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.

11. Subsequent Events

Management has determined that no material events or transactions occurred subsequent to April 30, 2024, that would require recognition or disclosure in the Fund’s financial statements.
