Investment objective

The Fund seeks maximum long-term total return, consistent with reasonable risk.

Market review

In a difficult year, higher-beta (more volatile) fixed income assets, such as high yield bonds and emerging market bonds, alternately outperformed and trailed the broad fixed income market. Overall, despite the benefit of the US Federal Reserve’s aggressive stimulus measures introduced in March, these riskier assets underperformed the Bloomberg Barclays US Aggregate Index for the 12-month period ended October 31, 2020.

Shortly before the Fund’s fiscal year began, in the summer of 2019, the Fed reversed its monetary policy in response to slowing global growth and a yield-curve inversion. After adhering to a monetary tightening cycle since 2015 and gradually normalized interest rates, the Federal Open Market Committee reverted to monetary easing with three 0.25-percentage-point rate cuts from late July through October. The reductions provided capital markets with greater confidence that central bank support could stabilize the economy, and created a strong tailwind for risk assets, which generally performed well through year-end 2019 and into early 2020.

The economic backdrop reversed in February and March when it became clear that widespread

Key contributors to Fund performance included:

•	timely shifts in exposure to risk and positive yield-curve management
•	increased exposure to higher-risk, higher-return segments
•	an overweight to and positive security selection in BBB-related credits.

Key detractors from Fund performance included:

•	exposure to high yield and emerging market bonds
•	exposure to Republic of Ecuador bonds

•	an overweight to commercial mortgage-backed securities (CMBS).

Portfolio management review

Delaware Diversified Income Fund

strong lockdown measures would be needed to control the spread of the global coronavirus pandemic. A market meltdown in early March was halted by rapid and aggressive fiscal stimulus measures and liquidity support from the Fed and other central banks. That enabled risk assets to rally strongly from late-March lows through the end of the fiscal year.

Within the Fund

For the fiscal year ended October 31, 2020, Delaware Diversified Income Fund outperformed its benchmark, the Bloomberg Barclays US Aggregate Index. The Fund’s Institutional Class shares gained 7.52%. The Fund’s Class A shares advanced 7.37% at net asset value and 2.51% at maximum offer price (both figures reflect all distributions reinvested). For the same period, the benchmark gained 6.19%. For complete, annualized performance of Delaware Diversified Income Fund, please see the table on page 4.

In a volatile year that included periods of both outperformance and underperformance, the
Fund outpaced its benchmark overall for the
12-month period, benefiting from timely
shifts in exposure to risk and overall positive
yield-curve management.

As calendar 2019 wound down, we increased the Fund's “capital cushion” by adding exposure to US Treasurys and mortgage-backed securities (MBS). By early 2020, the capital cushion had grown to more than 40% of the Fund's portfolio, which gave the Fund additional liquidity as markets became more volatile.

As the pandemic took hold and an economic stoppage ensued, the Fund significantly underperformed its benchmark. Nearly one-third of the Fund’s assets were in investment grade, high yield corporate, and emerging market bonds, all of which trailed the benchmark during the
risk-off period. When the fiscal and monetary tide shifted in late March, however, and higher-risk

sectors rallied, the Fund’s performance relative to its benchmark and peer group began to improve materially, and we began to draw down the capital cushion. By the end of the second quarter of 2020, we had reduced this allocation from 40% to about 25% by redeploying capital into investment grade corporate credit as well as high yield and emerging markets, the Fund’s structural
“plus” component.

This more aggressive positioning as the economy and capital markets recovered was a key contributor to the Fund’s performance. We increased the Fund’s exposure to these
higher-risk, higher-return segments to levels exceeding our earlier exposure. That strong tailwind carried the Fund through the rest of the fiscal year.

Elsewhere, yield-curve management was an important contributor to overall performance as the Fund’s portfolio was positioned for a steepening yield curve.

An overweight to – and good security selection within – BBB-rated bonds helped the Fund’s relative performance during the fiscal year. Within this credit tier, energy performed well, in large part driven by security selection. One energy holding, Noble Energy Inc., was purchased by Chevron Corp., a company with much higher credit quality. Noble rallied materially during the summer. Selling into strength, the Fund ended the year with a small position, down significantly from its exposure at the time of the merger.

The Fund also held coronavirus-related names, where volatility presented opportunities for us to add to the structural-plus components of the Fund’s portfolio, including companies affected by COVID-19 that were seeking liquidity. One example is Delta Air Lines Inc. We found value in Delta’s first-lien (secured) bonds, which the Fund still owns. Home improvement chain Lowe’s Companies Inc. also needed to source liquidity, and it continues to be a core holding for the Fund.

Table of Contents

Positive security selection within agency MBS also contributed to the Fund’s returns.

In terms of what didn’t work, relative to the benchmark, high yield bonds and emerging market bonds detracted from returns. Among emerging market bonds, the Fund had exposure to Aerovias de Mexico SA de CV, which filed for voluntary Chapter 11 restructuring in the second quarter of 2020. It was hurt as coronavirus-related travel restrictions and fear of the virus drove down passenger volumes significantly. However, the Fund participated in financing after the
Chapter 11 filing, and the Fund maintains exposure to the name from a secured position.

The Fund’s exposure to Republic of Ecuador bonds detracted from performance. Ecuador experienced deteriorating credit fundamentals as COVID-19 took hold. Compounding that, oil experienced a significant price shock in the early spring. The Fund continues to hold a small position in Republic of Ecuador bonds ahead of the country’s 2021 elections.

Offsetting solid security selection within agency MBS, exposure to certain nonagency MBS and an overweight to CMBS detracted from performance.

The backdrop for risk has continued to evolve along with the political landscape and the challenges posed by the virus. We still believe there is risk of a policy mistake, particularly on the fiscal side, heading into 2021. Central banks have appeared willing to do all they can to support economies. The US election risk is largely behind us, but uncertainty remains regarding the transition to a new administration. With a likely continuation of split government, markets have responded favorably to the possibility of moderate legislative policies.

As central bank support has helped tighten spreads and push up asset prices across the board, we may consider increasing the Fund’s capital cushion slightly once again. But overall, we remain comfortable with the Fund’s risk profile.

In this low rate environment, income is an important component of fixed income total returns. As we move into 2021, we continue to seek opportunities to find smart yield (yield with attractive risk-adjusted characteristics). We continue to search for credit issuers and securitized structures that we believe can survive these uncertain times.

We have positioned the Fund to out-yield its benchmark by carrying an overweight to spread product through investment grade corporate credit, CMBS, and structural plus sectors such as high yield and emerging market bonds. For now, we don’t anticipate a major shift in the Fund’s asset allocation.

The Fund used derivatives during the fiscal year, primarily for risk management purposes, including the use of interest rate futures to manage yield-curve risk and broader portfolio risks, and interest rate options to protect against large changes in interest rates. The Fund used currency forwards to hedge non-US dollar risk back to US dollars. The Fund also used foreign exchange (FX) forwards to gain access to a given currency, though we generally do this more directly through the bond market. Overall, these derivatives had a positive effect that was generally not material to the Fund’s performance (that is, it amounted to less than 0.50 percentage points during the fiscal year).

*The benchmark lifetime return is for Institutional Class share comparison only and is calculated using the last business day in the month of the Fund’s Institutional Class inception date.

¹ Returns reflect the reinvestment of all distributions and are presented both with and without the applicable sales charges described below. Returns do not reflect the deduction of taxes the shareholder would pay on Fund distributions or redemptions of Fund shares.

Expense limitations were in effect for certain classes during some or all of the periods shown in the “Fund and benchmark performance” table. Expenses for each class are listed on the “Fund expense ratios” table on page 6. Performance would have been lower had expense limitations not been in effect.

Institutional Class shares are not subject to a sales charge and are offered for sale exclusively to certain eligible investors. In addition, Institutional Class shares pay no distribution and service
(12b-1) fee.

Class A shares are sold with a maximum front-end sales charge of 4.50%, and have an annual
12b-1 fee of 0.25% of average daily net assets. Performance for Class A shares, excluding sales charges, assumes that no front-end sales
charge applied.

Class C shares are sold with a contingent deferred sales charge of 1.00% if redeemed during the first

12 months. They are also subject to an annual 12b-1 fee of 1.00% of average daily net assets. Performance for Class C shares, excluding sales charges, assumes either that contingent deferred sales charges did not apply or that the investment was not redeemed.

Class R shares are available only for certain retirement plan products. They are sold without a sales charge and have an annual 12b-1 fee of 0.50% of average daily net assets.

Class R6 shares are available only to certain 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. Class R6 shares pay no 12b-1 fee.

Fixed income securities and bond funds can lose value, and investors can lose principal, as interest rates rise. They also may be affected by economic conditions that hinder an issuer’s ability to make interest and principal payments on its debt.

The Fund may also be subject to prepayment risk, the risk that the principal of a bond that is held by a portfolio will be prepaid prior to maturity, at the time when interest rates are lower than what the bond was paying. A portfolio may then have to reinvest that money at a lower interest rate.

High yielding, non-investment-grade bonds (junk bonds) involve higher risk than investment
grade bonds.

The high yield secondary market is particularly susceptible to liquidity problems when institutional investors, such as mutual funds and certain other financial institutions, temporarily stop buying bonds for regulatory, financial, or other reasons. In addition, a less liquid secondary market makes it more difficult for the Fund to obtain precise valuations of the high yield securities in
its portfolio.

The Fund may invest in derivatives, which may involve additional expenses and are subject to

risk, including the risk that an underlying security or securities index moves in the opposite direction from what the portfolio manager anticipated. A derivatives transaction depends upon the counterparties’ ability to fulfill their contractual obligations.

If and when the Fund invests in forward foreign currency contracts or uses other investments
to hedge against currency risks, the Fund
will be subject to special risks, including counterparty risk.

The Fund may experience portfolio turnover in excess of 100%, which could result in higher transaction costs and tax liability.

International investments entail risks including fluctuation in currency values, differences in accounting principles, or economic or political instability. Investing in emerging markets can be riskier than investing in established foreign markets due to increased volatility, lower trading volume, and higher risk of market closures. In many emerging markets, there is substantially less publicly available information and the available information may be incomplete or misleading. Legal claims are generally more difficult to pursue.

IBOR risk is the risk that changes related to the use of the London interbank offered rate (LIBOR) or similar rates (such as EONIA) could have adverse impacts on financial instruments that reference these rates. The potential abandonment of these rates and transition to alternative rates could affect the value and liquidity of instruments that reference them and could affect investment strategy performance.

The disruptions caused by natural disasters, pandemics, or similar events could prevent the Fund from executing advantageous investment decisions in a timely manner and could negatively impact the Fund’s ability to achieve its investment objective and the value of the Fund’s investments.

Disclosure of Fund expenses

For the six-month period from May 1, 2020 to October 31, 2020 (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 May 1, 2020 to October 31, 2020.

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 tables 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 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 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.

The use of foreign currency exchange contracts, futures contracts, and swap contracts involves elements of market risk and risks in excess of the amounts disclosed in these financial statements. The notional amounts and foreign currency exchange contract presented above represent the Fund’s total exposure in such contracts, whereas only the net unrealized appreciation (depreciation) is reflected in the Fund’s net assets.

¹	See Note 8 in "Notes to financial statements."
²	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 $(11,067).

Equity securities 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 does not trade, the mean between the bid and ask prices will be used, which approximates fair value. Open-end investment companies are valued at their published net asset value (NAV). US government and agency securities are valued at the mean between the bid and ask prices, which approximates fair value. Other debt securities, credit default swap (CDS) contracts, interest rate swap options contracts (swaptions) and interest rate swap contracts are valued based upon valuations provided by an independent pricing service or broker/counterparty and reviewed by management. 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 mortgage obligations, 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. Foreign currency exchange contracts and foreign cross currency exchange contracts are valued at the mean between the bid and 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. Exchange-traded options are valued at the last reported sale price or, if no sales are reported, at the mean between the last reported bid and ask prices, which approximates fair value. Generally, other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith under the direction of the Trust’s Board of Trustees (Board). 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 are valued at fair value using methods approved by the Board.

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 year ended October 31, 2020 and for all open tax years (years ended October 31, 2017–October 31, 2019), 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.” 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. During the year ended October 31, 2020, 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.

Repurchase Agreements — The Fund may purchase certain US government securities subject to the counterparty’s agreement to repurchase them at an agreed upon date and price. The counterparty will be required on a daily basis to maintain the value of the collateral subject to the agreement at not less than the repurchase price (including accrued interest). The agreements are conditioned upon the collateral being deposited under the Federal Reserve book-entry system with the Fund’s custodian or a third-party sub-custodian. In the event of default or bankruptcy by the other party to the agreement, retention of the collateral may be subject to legal proceedings. All open repurchase agreements as of the date of this report were entered into on October 30, 2020, and matured on the next business day.

To Be Announced Trades (TBA) — The Fund may contract to purchase or sell securities for a fixed price at a transaction date beyond the customary settlement period (examples: when issued, delayed

delivery, forward commitment, or TBA transactions) consistent with the Fund’s ability to manage its investment portfolio and meet redemption requests. These transactions involve a commitment by the Fund to purchase or sell securities for a predetermined price or yield with payment and delivery taking place more than three days in the future, or after a period longer than the customary settlement period for that type of security. No interest will be earned by the Fund on such purchases until the securities are delivered or the transaction is completed; however, the market value may change prior to delivery.

Foreign Currency Transactions — Transactions denominated in foreign currencies are recorded at the prevailing exchange rates on the valuation date in accordance with the Fund’s prospectus. 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 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.

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 the accrual basis. 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. Realized gains (losses) on paydowns of asset- and mortgage-backed securities are classified as interest income. 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

Table of Contents

the dividends monthly and declares and pays dividends from net realized gain on investments, if any, 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 custodian when positive cash balances are maintained, which may be used to offset custody fees. The expenses paid under this arrangement are included on the “Statement of operations” under “Custodian fees” with the corresponding expenses offset included under “Less expenses paid indirectly.” For the year ended October 31, 2020, the Fund earned $16,775 under this arrangement.

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.” For the year ended October 31, 2020, the Fund earned $1,875 under this arrangement.

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

In accordance with the terms of its investment management agreement, the Fund pays Delaware Management Company (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 rate 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, and 0.425% on average daily net assets in excess of $2.5 billion.

DMC has contractually agreed to waive all or a portion, if any, of its management fee and/or
pay/reimburse the Fund to the extent necessary to ensure total annual operating 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) do not exceed 0.45% of the Fund’s Class A, Class C, Class R, and Institutional Class average daily net assets and 0.36% of the Fund’s Class R6 shares average daily net assets from November 1, 2019 through October 31, 2020.* For purposes of those waivers and reimbursements, nonroutine expenses may also include such additional costs and expenses, as may be agreed upon from time to time by the Board and DMC. These waivers and reimbursements apply only to expenses paid directly by the Fund and may be terminated only by agreement of DMC and the Fund. The waivers and reimbursements are accrued daily and received monthly.

DMC may seek investment advice and recommendations from its affiliates: Macquarie Investment Management Europe Limited, Macquarie Investment Management Austria Kapitalanlage AG, and Macquarie Investment Management Global Limited (MIMGL) (together, the “Affiliated Sub-Advisors”). The Manager may also permit these Affiliated Sub-Advisors to execute Fund security trades on behalf of the Manager and exercise investment discretion for securities in certain markets where 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 administration 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: 0.00475% of the first $35 billion; 0.0040% of the next $10 billion; and 0.0025% of aggregate average daily net assets in excess of $45 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 year ended October 31, 2020, the Fund was charged $126,816 for these services.

DIFSC is also the transfer agent and dividend disbursing agent of the Fund. For these services, DIFSC’s fees were 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; 0.005% of the next $20 billion; and 0.0025% of average daily net assets in excess of $50 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 year ended October 31, 2020, the Fund was charged $332,303 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 that 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, annual 12b-1 fees 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, tax, and regulatory reporting services to the Fund. For the year ended October 31, 2020, the Fund was charged $115,928 for internal legal, tax, 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 year ended October 31, 2020, DDLP earned $42,211 for commissions on sales of the Fund’s Class A shares. For the year ended October 31, 2020, DDLP received gross CDSC commissions of $185 and $10,991 on redemptions of the Fund’s Class A and Class C shares, respectively, and these

Table of Contents

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 the investment companies (Underlying Funds) 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 the Underlying Funds and the number of shares that are owned of the Underlying Funds at different times.

*The aggregate contractual waiver period covering this report is from April 1, 2019 through
March 1, 2021.

3. Investments

For the year ended October 31, 2020, the Fund made purchases and sales of investment securities other than short-term investments as follows:

Purchases other than US government securities	$1,812,524,594
Purchases of US government securities	2,126,678,841
Sales other than US government securities	1,422,963,272
Sales of US government securities	2,659,122,917

The tax cost of investments includes adjustments to net unrealized appreciation (depreciation) which may not necessarily be final tax cost basis adjustments, but approximate the tax basis unrealized gains and losses that may be realized and distributed to shareholders. At October 31, 2020, the cost and unrealized appreciation (depreciation) of investments and derivatives for federal income tax purposes for the Fund were as follows:

Cost of investments and derivatives	$3,569,678,542
Aggregate unrealized appreciation of investments and derivatives	$138,543,130
Aggregate unrealized depreciation of investments and derivatives	(38,084,769)
Net unrealized appreciation of investments and derivatives	$100,458,361

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, 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.

¹Security type is valued across multiple levels. Level 1 investments represent exchange-traded investments, Level 2 investments represent investments with observable inputs or matrix-priced investments, and Level 3 investments represent investments without observable inputs. The amounts attributed to Level 1 investments, Level 2 investments, and Level 3 investments represent the following percentages of the total market value of these security types:

	Level 1	Level 2	Level 3	Total
Loan Agreements	—	99.05%	0.95%	100.00%
Non-Agency Collateralized Mortgage Obligations	—	97.10%	2.90%	100.00%

²Foreign currency exchange contracts, futures contracts, and swap contracts are valued at the unrealized appreciation (depreciation) on the instrument at the year end.

The security that has been valued at zero on the "Schedule of investments" is considered to be a Level 3 investment in this table.

During the year ended October 31, 2020, there were no transfers between Level 1 investments, Level 2 investments, or Level 3 investments that had a significant impact to the Fund. The Fund's policy is to recognize transfers between levels 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, interim, or end of the year 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, interim, or end of

the year. Management has determined not to provide additional disclosure on Level 3 inputs since the Level 3 investments were not considered significant to the Fund’s net assets at the end of the year.

4. Dividend and Distribution Information

Income and long-term capital gain distributions are determined in accordance with federal income tax regulations, which may differ from US GAAP. Additionally, distributions from net gains on foreign currency transactions and net short-term gains on sales of investment securities are treated as ordinary income for federal income tax purposes. The tax character of dividends and distributions paid during the years ended October 31, 2020 and 2019 were as follows:

	Year ended
	10/31/20	10/31/19
Ordinary income	$109,553,098	$124,851,902
Return of capital	—	9,900,735
Total	$109,553,098	$134,752,637

5. Components of Net Assets on a Tax Basis

As of October 31, 2020, the components of net assets on a tax basis were as follows:

Shares of beneficial interest	$3,519,146,784
Undistributed ordinary income	1,481,592
Distributions payable	(1,475,197)
Unrealized appreciation of investments, foreign currencies, and derivatives	100,458,361
Net assets	$3,619,611,540

The differences between book basis and tax basis components of net assets are primarily attributable to tax deferral of losses on wash sales, mark-to-market of foreign currency exchange contracts, mark-to-market of swap contracts, mark-to-market of futures contracts, tax deferral of straddles losses, and market discount and premium on debt instruments.

For federal income tax purposes, capital loss carryforwards may be carried forward and applied against future capital gains. At October 31, 2020, the Fund utilized $108,459,141 of capital loss carryforwards.

7. Line of Credit

The Fund, along with certain other funds in the Delaware Funds (Participants), was a participant in a $250,000,000 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. The amount available under the Agreement was increased to $275,000,000 on May 6, 2020. The Agreement is to be used as described below and operates in substantially the same manner as the original Agreement. The line of credit available under the Agreement expires on November 2, 2020.

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 Fund had no amounts outstanding as of October 31, 2020, or at any time during the year then ended.

8. 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.

Foreign Currency Exchange Contracts — The Fund may enter into foreign currency exchange contracts and foreign cross 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 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 foreign currency exchange contracts and foreign cross 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 foreign currency exchange contracts and foreign cross 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.

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 October 31, 2020, the Fund posted $792,266 cash collateral as margin for open futures contracts.

During the year ended October 31, 2020, 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 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. There were no transactions in options written during the year ended October 31, 2020.

During the year ended October 31, 2020, the Fund entered into option contracts to manage the Fund’s exposure to changes in securities prices caused by interest rates or market conditions.

Swap Contracts — The Fund may enter into interest rate swap contracts and CDS contracts in the normal course of pursuing its investment objective. The Fund may enter into interest rate swaps to manage its sensitivity to interest rates or to hedge against changes in interest rates. 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.

Interest Rate Swaps. An interest rate swap contract is an exchange of interest rates between counterparties. In one instance, an interest rate swap involves payments received by the Fund from another party based on a variable or floating interest rate, in return for making payments based on a fixed interest rate. An interest rate swap can also work in reverse with the Fund receiving payments based on a fixed interest rate and making payments based on a variable or floating interest rate. Interest rate swaps may be used to adjust the Fund’s sensitivity to interest rates or to hedge against changes in interest rates. Periodic payments on such contracts are accrued daily and recorded as unrealized appreciation (depreciation) on swap contracts. Upon periodic payment (receipt) or termination of the contract, such amounts are recorded as realized gains or losses on swap contracts. The Fund’s maximum risk of loss from counterparty credit risk is the discounted net value of the cash flows to be received from/paid to the counterparty over the interest rate swap contract’s remaining life, to the extent that the amount is positive. 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. There were no interest rate swap contracts outstanding at October 31, 2020.

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

Table of Contents

basket of securities) to the counterparty. Credit events generally include, among others, bankruptcy, failure to pay, and obligation default.

During the year ended October 31, 2020, the Fund entered into CDS contracts as a purchaser and seller 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 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.

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 year ended October 31, 2020, the Fund entered into CDS contracts to hedge against credit events and to gain exposure to certain securities or markets.

Swaps Generally. For centrally cleared swaps, 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 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. The value of open swaps may differ from that which would be realized in the event the Fund terminated its position in the contract on a given day. Risks of entering into these contracts include the potential inability of the counterparty to meet the terms of the contracts. This type of risk is generally limited to the amount of favorable movement in the value of the underlying security, instrument, or basket of instruments, if any, at the day of default. Risks also arise from potential losses from adverse market movements and such losses could exceed the unrealized amounts shown on the “Schedule of investments.”

At October 31, 2020, for bilateral derivative contracts, the Fund received $50,000 in cash collateral for certain open derivatives, which is included in “Cash collateral due to broker” on the “Statement of assets and liabilities.”

9. 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 mitigate its counterparty risk. An ISDA Master Agreement is a bilateral agreement between the Fund and a counterparty that governs over-the-counter (OTC) derivatives and foreign exchange contracts and typically contains,

Table of Contents

Notes to financial statements

Delaware Diversified Income Fund

9. Offsetting (continued)

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 October 31, 2020, the Fund had the following assets and liabilities subject to offsetting provisions:

Offsetting of Financial Assets and Liabilities and Derivative Assets and Liabilities

Securities Lending

Securities lending transactions are entered into by the Fund under master securities lending agreements (each, an MSLA) which provide the right, in the event of default (including bankruptcy or insolvency), for the non-defaulting party to liquidate the collateral and calculate a net exposure to the defaulting party or request additional collateral. In the event that a borrower defaults, the Fund, as lender, would offset the market value of the collateral received against the market value of the securities loaned. When the value of the collateral is greater than that of the market value of the securities loaned, the lender is left with a net amount payable to the defaulting party. However, bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of an MSLA counterparty’s bankruptcy or insolvency. Under the MSLA, the borrower can resell or re-pledge the loaned securities, and the Fund can reinvest cash collateral, or, upon an event of default, resell or re-pledge the collateral (see also Note 10).

Table of Contents

As of October 31, 2020, the following table is a summary of the Fund's securities lending agreements by counterparty which are subject to offset under an MSLA:

Counterparty	Securities Loaned at Value	Cash Collateral Received^(a)	Fair Value of Non-Cash Collateral Received	Net Collateral Received	Net Exposure^(b)
The Bank of New York Mellon	$48,563,862	$(48,563,862)	$—	$(48,563,862)	$—
^(a)The value of the related collateral exceeded the value of the net position, purchase agreements, and securities lending transactions as of October 31, 2020.
^(b)Net exposure represents the receivable (payable) that would be due from (to) the counterparty in the event of default.

10. 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 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; and asset-backed securities as disclosed on the

10. Securities Lending (continued)

“Schedule of investments.” Securities purchased with cash collateral are valued at the market value. 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.

The following table reflects a breakdown of transactions accounted for as secured borrowings, the gross obligation by the type of collateral pledged, and the remaining contractual maturity of those transactions as of October 31, 2020:

Securities Lending Transactions		Overnight and continuous		Under 30 days		Between 30 & 90 days		Over 90 Days		Total
Repurchase Agreements		$50,252,323		$—		$—		$—		$50,252,323

At October 31, 2020, the value of securities on loan was $48,563,862, for which the Fund received cash collateral of $50,269,249. At October 31, 2020, the value of invested collateral was $50,252,323. Investments purchased with cash collateral are presented on the “Schedule of investments” under the caption “Securities Lending Collateral.”

11. Credit and Market Risk

Beginning in January 2020, global financial markets have experienced and may continue to experience significant volatility resulting from the spread of a novel coronavirus known as COVID-19. The outbreak of COVID-19 has resulted in travel and border restrictions, quarantines, supply chain disruptions, lower consumer demand and general market uncertainty. The effects of COVID-19 have and may continue to

Table of Contents

adversely affect the global economy, the economies of certain nations and individual issuers, all of which may negatively 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.

IBOR risk is the risk that potential changes related to the use of the London interbank offered rate (LIBOR) could have adverse impacts on financial instruments that reference LIBOR. The abandonment of LIBOR could affect the value and liquidity of instruments that reference LIBOR. The use of alternative reference rate products may impact investment strategy performance. These risks may also apply with respect to changes in connection with other interbank offered rates (“IBORs”), such as the euro interbank offered rate (Euribor) or the euro overnight index average (EONIA), which are also the subject of recent reform.

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 or consumer loans are paid back. Some of these securities are collateralized mortgage obligations (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.

Delaware Diversified Income Fund

11. Credit and Market Risk (continued)

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 United States. Consequently, acquisition and disposition of securities by the Fund may be inhibited. In addition, a significant portion of the 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 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 the loan agreement. Prepayment penalty fees are received upon the prepayment of a loan agreement by a 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.

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.”

12. 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.

13. General Motors Term Loan Litigation

The Fund received notice of a litigation proceeding related to a General Motors Corporation (G.M.) term loan participation previously held by the Fund in 2009. Because it was believed that the Fund was a secured creditor, the Fund received the full principal on the loans in 2009 after the G.M. bankruptcy. However, based upon a US Court of Appeals ruling the Motors Liquidation Company Avoidance Action Trust sought to recover such amounts arguing that, the Fund was an unsecured creditor and, as an unsecured creditor, the Fund should not have received payment in full. Based on available information related to the litigation and the Fund’s potential exposure, the Fund previously recorded a contingent liability of $15,959,167 and an asset of $4,787,750 based on the potential recoveries by the estate that resulted in a net decrease in the Fund’s NAV to reflect this potential recovery.

During the year, the plaintiff and the term loan lenders, which included the Fund, reached an agreement that resolved the disputes. The parties agreed to terms of a settlement agreement and presented the settlement agreement to the court for approval at a hearing on June 12, 2019. The court approved the settlement documentation and dismissed the case on July 2, 2019. The court’s approval of the settlement and dismissal of the case with prejudice became final on July 16, 2019.

The contingent liabilities and other assets were removed in connection with the case being settled, which resulted in the Fund recognizing a gain in the amount of the liabilities reversed.

14. Recent Accounting Pronouncements

In March 2017, FASB issued Accounting Standards Update (ASU), ASU 2017-08,
Receivables— Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities which amends the amortization period for certain callable debt securities purchased at a premium, shortening such period to the earliest call date. ASU 2017-08 does not require any accounting change for debt securities held at a discount; the discount continues to be amortized to maturity. ASU 2017-08 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Management has implemented ASU 2017-08 and determined that the impact of this guidance to the Fund’s net assets at the end of the year is not material.

Delaware Diversified Income Fund

14. Recent Accounting Pronouncements (continued)

In August 2018, the FASB issued an Accounting Standards Update (ASU), ASU 2018-13, which changes certain fair value measurement disclosure requirements. The ASU 2018-13, in addition to other modifications and additions, removes the requirement to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for the timing of transfers between levels and the valuation process for Level 3 fair value measurements. The ASU 2018-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. At this time, Management is evaluating the implications of these changes on the financial statements.

In March 2020, FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) – Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments in ASU 2020-04 provide optional temporary financial reporting relief from the effect of certain types of contract modifications due to the planned discontinuation of LIBOR and other interbank-offered based reference rates as of the end of 2021. ASU 2020-04 is effective for certain reference rate-related contract modifications that occur during the period March 12, 2020 through December 31, 2022. As of the financial reporting period, Management is evaluating the impact of applying this ASU.

15. Subsequent Events

On November 2, 2020, the Participants entered into an amendment to the Agreement for an amount of $225,000,000 to be used as described in Note 7. It operates in substantially the same manner as the original Agreement with the addition of an upfront fee of 0.05%, which was allocated across the Participants. The line of credit available under the agreement expires on November 1, 2021.

Management has determined that no other material events or transactions occurred subsequent to
October 31, 2020, that would require recognition or disclosure in the Fund's financial statements.

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Delaware Diversified Income Fund (one of the series constituting Delaware Group^® Adviser Funds, referred to hereafter as the “Fund”) as of October 31, 2020, the related statement of operations for the year ended October 31, 2020, the statements of changes in net assets for each of the two years in the period ended October 31, 2020, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of October 31, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended October 31, 2020 and the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of October 31, 2020 by correspondence with the custodian, transfer agents and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Delaware Diversified Income Fund

Liquidity Risk Management Program

The Securities and Exchange Commission (the “SEC”) has adopted Rule 22e-4 under the 1940 Act (the “Liquidity Rule”), which requires all open-end funds (other than money market funds) to adopt and implement a program reasonably designed to assess and manage a fund’s “liquidity risk,” defined as the risk that a fund could not meet requests to redeem shares issued by the fund without significant dilution of remaining investors’ interests in the fund.

The Fund has adopted and implemented a liquidity risk management program in accordance with the Liquidity Rule (the “Program”). The Board has designated the Division Director of the US Operational Risk Group of Macquarie Asset Management as the Program Administrator for the Fund.

As required by the Liquidity Rule, the Program includes policies and procedures that provide for: (1) assessment, management, and review (no less frequently than annually) of the Fund’s liquidity risk; (2) classification of each of the Fund’s portfolio holdings into one of four liquidity categories
(Highly Liquid, Moderately Liquid, Less Liquid, and Illiquid); (3) for funds that do not primarily hold assets that are Highly Liquid, establishing and maintaining a minimum percentage of the Fund’s net assets in Highly Liquid investments (called a “Highly Liquid Investment Minimum” or “HLIM”); and (4) prohibiting the Fund’s acquisition of Illiquid investments if, immediately after the acquisition, the Fund would hold more than 15% of its net assets in Illiquid assets. The Program also requires reporting to the SEC (on a
non-public basis) and to the Board if the Fund’s holdings of Illiquid assets exceed 15% of the Fund’s net assets. Funds with HLIMs must have procedures for addressing HLIM shortfalls, including reporting to the Board and, with respect to HLIM shortfalls lasting more than seven consecutive calendar days, reporting to the SEC (on a non-public basis).

In assessing and managing the Fund’s liquidity risk, the Program Administrator considers, as relevant, a variety of factors, including: (1) the Fund’s investment strategy and liquidity of portfolio investments during both normal and reasonably foreseeable stressed conditions; (2) short-term and long-term cash flow projections for the Fund during both normal and reasonably foreseeable stressed conditions; and (3) the Fund’s holdings of cash and cash equivalents and any borrowing arrangements. Classification of the Fund’s portfolio holdings in the four liquidity categories is based on the number of days it is reasonably expected to take to convert the investment to cash (for Highly Liquid and Moderately Liquid holdings) or to sell or dispose of the investment (for Less Liquid and Illiquid investments), in current market conditions without significantly changing the investment’s market value. The Fund primarily holds assets that are classified as Highly Liquid, and therefore is not required to establish an HLIM.

At a meeting of the Board held on May 19-21, 2020, the Program Administrator provided a written report to the Board addressing the Program’s operation and assessing the adequacy and effectiveness of its implementation for the period from December 1, 2018 through March 31, 2020. The report concluded that the Program is appropriately designed and effectively implemented and that it meets the requirements of Rule 22e-4 and the Fund’s liquidity needs.

Board consideration of Investment Advisory and Sub-Advisory Agreements for Delaware Diversified Income Fund at a meeting held August 11-13, 2020

At a meeting held on August 11-13, 2020 (the “Annual Meeting”), the Board of Trustees (the “Board”), including a majority of disinterested or independent Trustees, approved the renewal of the Investment Advisory and Sub-Advisory Agreements for Delaware Diversified Income Fund (the “Fund”). In making its decision, the Board considered information furnished at regular quarterly Board meetings, including reports detailing Fund performance, investment strategies, and expenses, as well as information prepared specifically in connection with the renewal of the investment advisory and sub-advisory contracts. Information furnished specifically in connection with the renewal of the Investment Management Agreement with Delaware Management Company (“DMC”), a series of Macquarie Investment Management Business Trust (“MIMBT”) and the Sub-Advisory Agreements with Macquarie Investment Management Global Limited (“MIMGL”), Macquarie Investment Management Europe Limited (“MIMEL”), and Macquarie Investment Management Austria Kapitalanlage AG (“MIMAK”) (the “Sub-Advisers”), included materials provided by DMC and its affiliates (collectively, “Macquarie Investment Management”) concerning, among other things, the nature, extent, and quality of services provided to the Fund; the costs of such services to the Fund; economies of scale; and the investment manager’s financial condition and profitability. In addition, in connection with the Annual Meeting, materials were

Delaware Diversified Income Fund

Board consideration of Investment Advisory and Sub-Advisory Agreements for Delaware Diversified Income Fund at a meeting held August 11-13, 2020 (continued)

provided to the Trustees in May 2020, including reports provided by Broadridge Financial Solutions (“Broadridge”). The Broadridge reports compared the Fund’s investment performance and expenses with those of other comparable mutual funds. The Independent Trustees reviewed and discussed the Broadridge reports with independent legal counsel to the Independent Trustees. In addition to the information noted above, the Board also requested and received information regarding DMC’s policy with respect to advisory fee levels and its breakpoint philosophy; the structure of portfolio manager compensation; comparative client fee information; and any constraints or limitations on the availability of securities for certain investment styles, which had in the past year inhibited, or which were likely in the future to inhibit, the investment manager’s ability to invest fully in accordance with Fund policies.

In considering information relating to the approval of the Fund’s advisory and sub-advisory agreements, as applicable, the Independent Trustees received assistance and advice from and met separately with independent legal counsel to the Independent Trustees and also received assistance and advice from an experienced and knowledgeable independent fund consultant, JDL Consultants, LLC (“JDL”). Although the Board gave attention to all information furnished, the following discussion identifies, under separate headings, the primary factors taken into account by the Board during its contract renewal considerations.

Nature, extent, and quality of services. The Board considered the services provided by DMC to the Fund and its shareholders. In reviewing the nature, extent, and quality of services, the Board considered reports furnished to it throughout the year, which covered matters such as the relative performance of the Fund; compliance of portfolio managers with the investment policies, strategies, and restrictions for the Fund; compliance by DMC and Delaware Distributors, L.P. (together, “Management”) personnel with the Code of Ethics adopted throughout the Delaware Funds^®by Macquarie (“Delaware Funds”); and adherence to fair value pricing procedures as established by the Board. The Board was pleased with the current staffing of DMC and the emphasis placed on research in the investment process. The Board recognized DMC’s receipt of certain favorable industry distinctions during the past several years. The Board gave favorable consideration to DMC’s efforts to control expenses while maintaining service levels committed to Fund matters. The Board also noted the benefits provided to Fund shareholders through (a) each shareholder’s ability to: (i) exchange an investment in one Delaware Fund for the same class of shares in another Delaware Fund without a sales charge, or (ii) reinvest Fund dividends into additional shares of the Fund or into additional shares of other Delaware Funds, and (b) the privilege to combine holdings in other Delaware Funds to obtain a reduced sales charge. The Board was satisfied with the nature, extent, and quality of the overall services provided by DMC.

Nature, extent, and quality of services. The Board considered the services provided by each
Sub-Adviser to the Fund. In reviewing the nature, extent, and quality of services, the Board considered reports furnished to it throughout the year at regular Board Meetings covering matters such as relative performance of the Fund; compliance of portfolio managers with the investment policies, strategies, and restrictions for the Fund; the compliance of Sub-Adviser personnel with its Code of Ethics; and adherence to fair value pricing procedures as established by the Board. The Board was pleased with the

Table of Contents

current staffing of the Sub-Advisers and the emphasis placed on research in the investment process. The Board was satisfied with the nature, extent, and quality of the overall services provided by the
Sub-Advisers.

Investment performance. The Board placed significant emphasis on the investment performance of the Fund in view of the importance of investment performance to shareholders. Although the Board considered performance reports and discussions with portfolio managers at Investment Committee meetings throughout the year, the Board gave particular weight to the Broadridge reports furnished for the Annual Meeting. The Broadridge reports prepared for the Fund showed the investment performance of its Class A shares in comparison to a group of similar funds as selected by Broadridge (the “Performance Universe”). A fund with the best performance ranked first, and a fund with the poorest performance ranked last. The highest/best performing 25% of funds in the Performance Universe make up the first quartile; the next 25%, the second quartile; the next 25%, the third quartile; and the
poorest/worst performing 25% of funds in the Performance Universe make up the fourth quartile. Comparative annualized performance for each Fund was shown for the past 1-, 3-, 5-, and 10-year periods, to the extent, applicable, ended January 31, 2020. The Board’s objective is that the Fund’s performance for the 1-, 3-, and 5-year periods be at or above the median of its Performance Universe.

The Performance Universe for the Fund consisted of the Fund and all retail and institutional core plus bond funds as selected by Broadridge. The Broadridge report comparison showed that the Fund’s total return for the 1-year period was in the first quartile of its Performance Universe. The report further showed that the Fund’s total return for the 3-year period was in the second quartile of its Performance Universe and the Fund’s total return for the 5- and 10-year periods was in the third quartile of its Performance Universe. The Board was satisfied with performance.

Comparative expenses. The Board considered expense data for the Delaware Funds. Management provided the Board with information on pricing levels and fee structures for the Fund as of its most recently completed fiscal year. The Board also focused on the comparative analysis of effective management fees and total expense ratios of the Fund versus effective management fees and total expense ratios of a group of similar 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 (as reported by each fund) within the Expense Group, taking into account any applicable breakpoints and fee waivers. The Fund’s total expenses were also compared with those of its Expense Group. The Broadridge total expenses, for comparative consistency, were shown by Broadridge for Class A shares and comparative total expenses including 12b-1 and non-12b-1 service fees. The Board’s objective is for the Fund’s total expense ratio to be competitive with those of the peer funds within its Expense Group.

The expense comparisons for the Fund showed that its actual management fee and total expenses were in the quartile with the second lowest expenses of its Expense Group. The Board was satisfied with the management fee and total expenses of the Fund in comparison to those of its Expense Group as shown in the Broadridge report.

services to each of the individual funds and the Delaware Funds as a whole. Specific attention was given to the methodology used by DMC in allocating costs for the purpose of determining profitability. Management stated that the level of profits of DMC, to a certain extent, reflects recent operational cost savings and efficiencies initiated by DMC. The Board considered DMC’s efforts to improve services provided to Fund shareholders and to meet additional regulatory and compliance requirements resulting from recent industry-wide Securities and Exchange Commission initiatives. The Board also considered the extent to which DMC 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 service provider to the Delaware Funds and the benefits from allocation of fund brokerage to improve trading efficiencies. As part of its work, the Board also reviewed a report prepared by JDL regarding MIMBT profitability as compared to certain peer fund complexes and the Independent Trustees met with JDL personnel to discuss DMC’s profitability in such context. The Board found that the management fees were reasonable in light of the services rendered and the level of profitability of DMC.

Management profitability. Trustees were also given available information on profits being realized by each of the Sub-Advisers in relation to the services being provided to the Fund and in relation to the Sub-Adviser’s overall investment advisory business, but believed such information to be of limited relevance because the sub-advisory fees are paid by DMC out of its management fee, and changes in the level of sub-advisory fees have no impact on Fund expenses. The Board was also provided information on potential fall-out benefits derived or to be derived by the Sub-Advisers in connection with their relationship to the Fund, such as reputational enhancement, soft dollar arrangements, or commissions paid to affiliated broker/dealers, as applicable.

Economies of scale. The Trustees considered whether economies of scale are realized by DMC as the Fund’s assets increase and the extent to which any economies of scale are reflected in the level of management fees charged. The Trustees reviewed the Fund’s advisory fee pricing and structure, approved by the Board and shareholders, which includes breakpoints, and which applies to most funds in the Delaware Funds complex. Breakpoints in the advisory fee occur when the advisory fee rate is reduced on assets in excess of specified levels. 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 are exceeded. The Board noted that, as of March 31, 2020, the Fund’s net assets exceeded the final breakpoint level. The Board believed that, given the extent to which economies of scale might be realized by DMC and its affiliates, the schedule of fees under the Investment Management Agreement provides a sharing of benefits with the Fund and its shareholders.

Board of trustees / directors and officers addendum

Delaware Funds^® by Macquarie

A mutual fund is governed by a Board of Trustees/Directors (“Trustees”), which has oversight responsibility for the management of a fund’s business affairs. Trustees establish procedures and oversee and review the performance of the investment manager, the distributor, and others who perform services for the fund. The independent fund trustees, in particular, are advocates for shareholder interests.

Caring for your portfolio

Over a lifetime, things change. When they do, it’s important to ensure that your investments stay in tune with your personal situation.

If you decide to make some changes, check
out the convenient options provided by Macquarie Investment Management. We try to make it easy for you to avoid some of the sales charges that you might otherwise have to pay when you withdraw and invest your money with another firm.

Most importantly, you may generally
exchange all or part of your shares in one Delaware Funds^® by Macquarie mutual fund for shares of the same class of another fund without paying a front-end sales charge or a contingent deferred sales charge (CDSC).

Choose the investment method suitable for you

After you’ve evaluated your overall investments, you have choices about how to implement
any changes:

1. Move assets all at once at any time.

2. Migrate funds to a different investment slowly through a systematic exchange. You can arrange automatic monthly exchanges of your shares in one Delaware fund for those in another Delaware fund. Systematic exchanges are subject to the same rules as regular exchanges, which are explained in the right column, including a $100 minimum monthly amount per fund.

3. Use our automatic investing plan for future investments in different vehicles. To allocate your future investments differently, the Macquarie Investment Management automatic investing plan allows you to make regular monthly or quarterly investments directly from your checking account.

Important notes about exchanging or redeeming shares

For automated exchanges, a minimum exchange of $100 per fund is required monthly. If the value of your account is $5,000 or more, you can make systematic withdrawals of at least $25 monthly,
or $75 quarterly. If the annual amount you withdraw is less than 12% of your account balance at the time the systematic withdrawal plan is established, the CDSC ordinarily applicable to certain fund classes will be waived. More details are available in your prospectus or at
delawarefunds.com/literature.

If you exchange shares from Class R shares of any fund, you will pay any applicable sales charge on your new shares.

When exchanging Class C shares of one fund for the same class of shares in other funds, your new shares will be subject to the same CDSC as the shares you originally purchased. The holding period for the CDSC will also remain the same, with the amount of time you held your original shares being credited toward the holding period of your new shares.

You do not pay sales charges on shares that you acquired through the reinvestment of dividends. You may have to pay taxes on your exchange. When you exchange shares, you are purchasing shares in another fund, so you should be sure to get a copy of the fund’s prospectus and
read it carefully before buying shares through an exchange.

We may refuse the purchase side of any exchange request if, in the manager’s judgment, the fund would be unable to invest effectively in accordance with its investment objective and policies, or would otherwise potentially be adversely affected.

Investment objective

The Fund seeks long-term capital appreciation by investing in equity securities of companies we believe have the potential for sustainable free cash flow growth.

Market review

It was a challenging year for economies the world over and yet, despite growing uncertainty, the US stock market did relatively well. During the past 12 months, the S&P 500^® Index rose by 9.71%, a healthy gain for even the most typical of times. Even so, it was a bumpy ride, marked by several unexpected events. Most notable was a wave of local COVID-19-related shelter-in-place orders that shuttered many offices, schools, and entertainment venues, in some cases for months.

Even before news of the novel coronavirus hit US media outlets in December 2019, key domestic indicators had already started to give off mixed messages. The uncertain US-China relationship led to a corporate pullback on capital spending. The domestic residential housing market continued to expand, however, and US markets continued an upward trajectory through most of the winter despite news that the coronavirus had spread beyond its origin in Wuhan, China.

Regardless of policy outcomes and oscillating investor sentiment in any given period, we remain consistent in our
long-term investment philosophy: we want the Fund to own what we view as strong secular-growth companies with solid business models and competitive positions that we believe can grow market share and have the potential to deliver shareholder value in a variety market environments.

Portfolio management review

Delaware U.S. Growth Fund

In February 2020, when the growing number of European-based outbreaks prompted international concern and then, later in the month, when the United States announced its first COVID-19-related death, markets began to slide. In mid-March, stay-at-home orders devastated the economy and the US stock market plunged to its lowest point since 2017.

The home-based economy hit workers hard,
with 20.5 million non-farm jobs lost in April alone. Gross domestic product (GDP) plummeted, dropping a record-setting 9.1% in the
second quarter.

Late spring ushered in a combination of mild weather and eased restrictions, which led to the beginning of a slow economic rebound. Restaurateurs set up tables outside, retailers established masking rules and occupancy limits, and entertainers found creative options for physically distanced live events. At the same time, factories reopened, and corporations and employees hit a work-from-home stride, displaying a greater-than-expected ability to maintain productivity.

Still, even as Main Street merchants managed to hold on amid the pandemic, giants such as Alphabet Inc. (Google), Facebook Inc., Amazon.com Inc., Microsoft Corp., and Netflix Inc. buoyed the stock market. They gained traction as consumers, watchers, and scrollers spent more time at home.

At the same time, the US Federal Reserve shaped monetary policy to support the economy, including a never-before-used strategy to inject liquidity: buying corporate bonds. The combination pushed market prices up.

Later in the fiscal period, equities flagged as falling temperatures accompanied an uptick in
COVID-19 cases and uncertainty over the US election. Even so, the US economy ended the period in solidly favorable territory. Overseas, meanwhile, international markets had the same

struggles as the US, but didn’t recover quite as well. The MSCI EAFE (Europe, Australasia, Far East) Index lost 6.86% during the fiscal year. Emerging markets participated in
post-March market gains and ended the 12-month period up 8.25%.

Within the Fund

For the fiscal year ended October 31, 2020, Delaware U.S. Growth Fund underperformed its benchmark, the Russell 1000 Growth Index. The Fund’s Institutional Class shares gained 27.10%. The Fund’s Class A shares advanced 26.82% at net asset value and 19.53% at maximum offer price (both figures reflect all distributions reinvested). For the same period, the benchmark gained 29.22%. For complete, annualized performance of Delaware U.S. Growth Fund, please see the table on page 5.

Strong relative performance in information technology was unable to overcome weak relative performance in financials. On a company level, the following stocks were the most significant contributors and detractors during the period.

Twilio Inc., a cloud communications platform, contributed to performance during the period. We believe that instant digital communication with customers and employees across any medium in any geography is a hugely complex problem that businesses increasingly need to solve. We think Twilio, as the leading communications-as-a-service (CaaS) platform – several multiples the size of its next largest competitor – appears likely to be the primary beneficiary of that trend. The addressable market is tens of billions of procurement dollars and essentially untapped with Twilio’s still-negligible penetration, which we believe appears set to expand meaningfully.

ServiceNow Inc., a cloud-based software company focusing on core systems for IT departments, added to performance during the period. Led by CEO Bill McDermott, the

Table of Contents

company’s new management team delivered strong growth and profitability against concern about slowing performance during the management transition period. During the
COVID-19 pandemic, ServiceNow also successfully stabilized and reaccelerated growth in a rapid time frame as it focused on rapidly digitizing large companies, a trend that, in our view, has the potential to lead to additional tailwinds in upcoming years.

PayPal Holdings Inc., a technology platform company that enables digital and mobile payments on behalf of consumers and merchants, also contributed to performance. PayPal noted marked acceleration for new users, retention, engagement, and volumes across its entire brand portfolio as COVID-19 effects have pulled forward consumer ecommerce demand across the globe. Third-party data released in June showed significant acceleration in new application installs for PayPal and Venmo (another digital payment provider). This has helped sustain the stock’s outperformance. In our opinion, the strength across the company’s portfolio highlights the reach, scale, and technology of a business that is uniquely situated, which may enable it to capture market share of digital payments.

Constellation Brands Inc., a producer and marketer of beer, wine, and spirits, detracted from performance during the period. Investors became concerned about the company’s leverage profile on its balance sheet as well as the Mexican government taking what were seen as several unexpected anti-business initiatives that hurt Constellation. We sold the Fund's position in favor of pursuing more attractive opportunities.

CME Group Inc., a financial market company operating options and futures exchanges, also detracted from performance. CME’s stock underperformed the market during the period due to generally lower volumes on its futures exchange. Since the company’s cost base is

relatively fixed, lower volumes directly led to lower earnings and cash flows. Although we admire the company’s business model and management team, we exited the position because we believe the probability of sustained lower volumes has increased as a result of global central bank interventions, thereby reducing interest rate volatility and associated futures trading volumes.

Dollar Tree Inc., a chain of discount variety stores, likewise reduced the Fund’s performance. Although we considered re-underwriting the position, we ultimately concluded that Dollar Tree requires a new management team to realize the substantial value creation opportunities related to a turnaround at its Family Dollar subsidiary and expanding price tiers at Dollar Tree. Given our increased concerns about challenging fundamentals and management execution, we decided to redeploy assets elsewhere.

A global pandemic and significant market volatility marked the fiscal period. To that end, we took advantage of the sharp COVID-19 related selloff to purchase a handful of companies that, although we had admired, had not previously fit our valuation discipline. In our estimation, these companies offer the potential for outperformance across a wide breadth of industries.

At Jackson Square, our portfolio turnover increased during the period. We focused on seeking to take advantage of market volatility to purchase some securities that were trading at levels below our estimation of intrinsic business value than we have seen since the global financial crisis more than a decade ago. We also pruned from the Fund's portfolio companies that struggled with fundamentals or carried a larger amount of leverage than we thought prudent during this crisis. We will remain vigilant in looking for more opportunities to enhance and refine the Fund’s portfolio.

Regardless of policy outcomes and oscillating investor sentiment in any given period, we remain

¹ The “Performance of a $10,000 investment” graph assumes $10,000 invested in Institutional Class and Class A shares of the Fund on October 31, 2010, and includes the effect of a 5.75% front-end sales charge (for Class A shares) and the reinvestment of all distributions. The graph does not reflect the deduction of taxes the shareholders would pay on Fund distributions or redemptions of Fund shares. Expense limitations were in effect for some or all of the periods shown. Performance would have been lower had expense limitations not been in effect. Expenses are listed in the “Fund expense ratios” table on page 6. Please note additional details on pages 5
through 8.

The graph also assumes $10,000 invested in the Russell 1000 Growth Index as of
October 31, 2010. The Russell 1000 Growth Index measures the performance of the large-cap growth segment of the US equity universe. It

includes those Russell 1000 companies with higher price-to-book ratios and higher forecasted growth values.

The S&P 500 Index, mentioned on page 1, measures the performance of 500 mostly large-cap stocks weighted by market value, and is often used to represent performance of the US stock market.

The MSCI EAFE (Europe, Australasia, Far East) Index, mentioned on page 2, represents large- and mid-cap stocks across 21 developed markets, excluding the United States and Canada. The index covers approximately 85% of the free float-adjusted market capitalization in each country. Index “net” return approximates the minimum possible dividend reinvestment, after deduction of withholding tax at the highest possible rate. Index “gross” return approximates the maximum possible dividend reinvestment.

Notes to financial statements

Delaware U.S. Growth Fund

October 31, 2020

Delaware Group^® Adviser Funds (Trust) is organized as a Delaware statutory trust and offers two series: Delaware Diversified Income Fund and Delaware U.S. Growth Fund. These financial statements and the related notes pertain to Delaware U.S. Growth Fund (Fund). The Trust is an open-end investment company. The Fund is considered diversified under the Investment Company Act of 1940, as amended, 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 5.75%. Class A share purchases of $1,000,000 or more will incur a contingent deferred sales charge (CDSC) instead of a front-end sales charge of 1.00%, if redeemed during the first year, and 0.50% during the second year, provided that Delaware Distributors, L.P. (DDLP) paid a financial advisor a commission on the purchase of those shares. Class C shares are sold with a 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

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 year ended October 31, 2020 and for all open tax years (years ended
October 31, 2017–October 31, 2019), and has concluded that no provision for federal income tax is

Table of Contents

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 year ended October 31, 2020, the Fund did not incur any interest or tax penalties.

Class Accounting — Investment income, common expenses, and 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.

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 the accrual basis. Distributions received from investments in real estate investment trusts (REITs) are recorded as dividend income on the ex-dividend date, subject to reclassification upon notice of the character of such distributions by the issuer. The Fund declares and pays dividends from net investment income and distributions from net realized gain on investments, if any, 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 Delaware Management Company (DMC), a series of Macquarie Investment Management Business Trust and the

Table of Contents

Notes to financial statements

Delaware U.S. Growth Fund

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

(continued)

investment manager, an annual fee which is calculated daily and paid monthly at the rate 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 may permit its affiliates, Macquarie Investment Management Global Limited (MIMGL) and Macquarie Funds Management Hong Kong Limited (together, the “Affiliated Sub-Advisors”), to execute Fund equity security trades on behalf of the Manager. The Manager may also seek quantitative support from MIMGL. 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, may pay each Affiliated Sub-Advisor a portion of its investment management fee.

DMC has contractually agreed to waive all or a portion, if any, of its management fee and/or
pay/reimburse the Fund to the extent necessary to ensure total annual operating expenses (excluding any distribution and service (12b-1) fees, taxes, interest, acquired fund fees and expenses, 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), do not exceed 0.84% of the Fund’s average daily net assets of Class A, Class C, Class R, and Institutional Class shares and 0.62% of the Fund’s average daily net assets of Class R6 shares from November 1, 2019 through October 31, 2020.* 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.

Jackson Square Partners, LLC (JSP) furnishes investment sub-advisory services to the Fund. For these services, DMC, not the Fund, pays JSP fees based on the aggregate average daily net assets of the Fund at the following annual rate: 0.39% of the first $500 million; 0.36% of the next $500 million; 0.33% of the next $1.5 billion; and 0.30% of aggregate average daily net assets in excess of $2.5 billion.

NAV basis. This amount is included on the “Statement of operations” under “Dividend disbursing and transfer agent fees and expenses.” For the year ended October 31, 2020, the Fund was charged $219,437 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%, of the average daily net assets of the Class A shares, 1.00% of the average daily net assets of the Class C shares, and 0.50% of the average daily net assets of the Class R shares. 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, tax, and regulatory reporting services to the Fund. For the year ended October 31, 2020, the Fund was charged $69,617 for internal legal, tax, 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 year ended October 31, 2020, DDLP earned $18,069 for commissions on sales of the Fund’s Class A shares. For the year ended October 31, 2020, DDLP received gross CDSC commissions of $7 and $847 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.

*The aggregate contractual waiver period covering this report is from February 28, 2019 through March 1, 2021.

3. Investments

For the year ended October 31, 2020, the Fund made purchases and sales of investment securities other than short-term investments as follows:

Purchases

$1,278,577,971

Table of Contents

Notes to financial statements

Delaware U.S. Growth Fund

3. Investments (continued)

Sales

$1,815,615,816

The tax cost of investments includes adjustments to net unrealized appreciation (depreciation) which may not necessarily be the final tax cost basis adjustments, but approximate the tax basis unrealized gains and losses that may be realized and distributed to shareholders. At October 31, 2020, the cost and unrealized appreciation (depreciation) of investments for federal income tax purposes for the Fund were as follows:

Cost of investments	$1,663,402,092
Aggregate unrealized appreciation of investments	$806,917,514
Aggregate unrealized depreciation of investments	(25,086,471)
Net unrealized appreciation of investments	$781,831,043

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

Table of Contents

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 October 31, 2020:

	Level 1
Securities
Assets:
Common Stock	$2,436,236,170
Short-Term Investments	8,996,965
Total Value of Securities	$2,445,233,135

During the year ended October 31, 2020, there were no transfers between Level 1 investments, Level 2 investments, or Level 3 investments. The Fund’s policy is to recognize transfers between levels 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, interim, or end of the period in relation to the Fund's net assets. During the year ended October 31, 2020, there were no Level 3 investments.

4. Dividend and Distribution Information

Income and long-term capital gain distributions are determined in accordance with federal income tax regulations, which may differ from US GAAP. Additionally, distributions from net short-term gains on sales of investment securities are treated as ordinary income for federal income tax purposes. The tax character of dividends and distributions paid during the years ended October 31, 2020 and 2019 was as follows:

	Year ended
	10/31/20	10/31/19
Ordinary income	$—	$24,678,317
Long-term capital gains	239,627,125	388,127,863
Total	$239,627,125	$412,806,180

5. Components of Net Assets on a Tax Basis

As of October 31, 2020, the components of net assets on a tax basis were as follows:

Shares of beneficial interest	$1,392,576,570
Undistributed ordinary income	20,422,472
Undistributed long-term capital gains	248,964,541
Unrealized appreciation of investments	781,831,043
Net assets	$2,443,794,626

The differences between book basis and tax basis components of net assets are primarily attributable to tax deferral of losses on wash sales.

6. Capital Shares

Transactions in capital shares were as follows:

	Year ended
	10/31/20	10/31/19
Shares sold:
Class A	1,218,848	884,948

Certain shareholders may exchange shares of one class for shares of another class in the same Fund. These exchange transactions are included as subscriptions and redemptions in the previous table and on the “Statements of changes in net assets.” For the years ended October 31, 2020 and 2019, the Fund had the following exchange transactions:

	Exchange Redemptions			Exchange Subscriptions

7. Line of Credit

The Fund had no amounts outstanding as of October 31, 2020, or at any time during the year then ended.

8. Securities Lending

Table of Contents

Notes to financial statements

Delaware U.S. Growth Fund

8. Securities Lending (continued)

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.

During the year ended October 31, 2020, the Fund had no securities out on loan.

9. Credit and Market Risk

Beginning in January 2020, global financial markets have experienced and may continue to experience significant volatility resulting from the spread of a novel coronavirus known as COVID-19. The outbreak of COVID-19 has resulted in travel and border restrictions, quarantines, supply chain disruptions, lower consumer demand, and general market uncertainty. The effects of COVID-19 have and may continue to

Table of Contents

adversely affect the global economy, the economies of certain nations and individual issuers, all of which may negatively impact the Fund's performance.

The Fund invested in growth stocks (such as those in the technology sector), which reflect projections of future earnings and revenue. These prices may rise or fall dramatically depending on whether those projections are met. These companies’ stock prices may be more volatile, particularly over the
short term.

The Fund invests a significant portion of its assets in small companies and may be subject to certain risks associated with ownership of securities of such companies. Investments in small sized companies may be more volatile than investments in larger companies for a number of reasons, which include limited financial resources or a dependence on narrow product lines.

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. As of October 31, 2020, there were no Rule 144A securities held by
the Fund.

10. Contractual Obligations

11. Recent Accounting Pronouncements

In August 2018, FASB issued an Accounting Standards Update (ASU), ASU 2018-13, which changes certain fair value measurement disclosure requirements. ASU 2018-13, in addition to other modifications and additions, removes the requirement to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for the timing of transfers between levels and the valuation process for Level 3 fair value measurements. ASU 2018-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. At this time, Management is evaluating the implications of these changes on the financial statements.

12. Subsequent Events

On November 2, 2020, the Participants entered into an amendment to the Agreement for an amount of $225,000,000 to be used as described in Note 7. It operates in substantially the same manner as the

original Agreement with the addition of an upfront fee of 0.05%, which was allocated across the Participants. The line of credit available under the agreement expires on November 1, 2021.

On November 18, 2020, the Board approved the reorganization (Reorganization) of the Fund into and with the substantially similar, existing Jackson Square Large-Cap Growth Fund. The Reorganization is subject to the approval of Fund shareholders at a special shareholder meeting.

Management has determined that no other material events or transactions occurred subsequent to
October 31, 2020, that would require recognition or disclosure in the Fund's financial statements.

Opinion on the Financial Statements

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Delaware U.S. Growth Fund (one of the series constituting Delaware Group^® Adviser Funds referred to hereafter as the “Fund”) as of October 31, 2020, the related statement of operations for the year ended October 31, 2020, the statements of changes in net assets for each of the two years in the period ended October 31, 2020, including the related notes, and the financial highlights for each of the periods indicated therein (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Fund as of October 31, 2020, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period ended October 31, 2020 and the financial highlights for each of the periods indicated therein in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our procedures included confirmation of securities owned as of October 31, 2020 by correspondence with the custodian and transfer agents. We believe that our audits provide a reasonable basis for our opinion.

Board consideration of Investment Advisory and Sub-Advisory Agreements for Delaware U.S. Growth Fund at a meeting held August 11-13, 2020

At a meeting held on August 11-13, 2020 (the “Annual Meeting”), the Board of Trustees (the “Board”), including a majority of disinterested or independent Trustees, approved the renewal of the Investment Advisory and Sub-Advisory Agreements for Delaware U.S. Growth Fund (the “Fund”). In making its decision, the Board considered information furnished at regular quarterly Board meetings, including reports detailing Fund performance, investment strategies, and expenses, as well as information prepared specifically in connection with the renewal of the investment advisory and sub-advisory contracts. Information furnished specifically in connection with the renewal of the Investment Management Agreement with Delaware Management Company (“DMC”), a series of Macquarie Investment Management Business Trust (“MIMBT”) and the Sub-Advisory Agreement with Jackson Square Partners, LLC (“JSP”), included materials provided by DMC and its affiliates (collectively, “Macquarie Investment Management”) concerning, among other things, the nature, extent, and quality of services provided to the Fund; the costs of such services to the Fund; economies of scale; and the investment manager’s financial condition and profitability. In addition, in connection with the Annual Meeting, materials were provided to the Trustees in May 2020, including reports provided by Broadridge Financial Solutions (“Broadridge”). The Broadridge reports compared the Fund’s investment performance and expenses with those of other comparable mutual funds. The Independent Trustees reviewed and discussed the Broadridge reports with independent legal counsel to the Independent Trustees. In addition to the information noted above, the Board also requested and received information regarding DMC’s policy with respect to advisory fee levels and its breakpoint philosophy; the structure of portfolio manager compensation; comparative client fee information; and any constraints or limitations

on the availability of securities for certain investment styles, which had in the past year inhibited, or which were likely in the future to inhibit, the investment manager’s ability to invest fully in accordance with Fund policies.

Nature, extent, and quality of services. The Board considered the services provided by DMC to the Fund and its shareholders. In reviewing the nature, extent, and quality of services, the Board considered reports furnished to it throughout the year, which covered matters such as the relative performance of the Fund; compliance of portfolio managers with the investment policies, strategies, and restrictions for the Fund; compliance by DMC and Delaware Distributors, L.P. (together, “Management”) personnel with the Code of Ethics adopted throughout the Delaware Funds^® by Macquarie (“Delaware Funds”); and adherence to fair value pricing procedures as established by the Board. The Board was pleased with the current staffing of DMC and the emphasis placed on research in the investment process. The Board recognized DMC’s receipt of certain favorable industry distinctions during the past several years. The Board gave favorable consideration to DMC’s efforts to control expenses while maintaining service levels committed to Fund matters. The Board also noted the benefits provided to Fund shareholders through (a) each shareholder’s ability to: (i) exchange an investment in one Delaware Fund for the same class of shares in another Delaware Fund without a sales charge, or (ii) reinvest Fund dividends into additional shares of the Fund or into additional shares of other Delaware Funds, and (b) the privilege to combine holdings in other Delaware Funds to obtain a reduced sales charge. The Board was satisfied with the nature, extent, and quality of the overall services provided by DMC.

Nature, extent, and quality of services. The Board considered the services provided by JSP to the Fund. In reviewing the nature, extent, and quality of services, the Board considered reports furnished to it throughout the year at regular Board Meetings covering matters such as relative performance of the Fund; compliance of portfolio managers with the investment policies, strategies, and restrictions for the Fund; the compliance of Sub-Adviser personnel with its Code of Ethics; and adherence to fair value pricing procedures as established by the Board. The Board was pleased with the current staffing of JSP and the emphasis placed on research in the investment process. The Board was satisfied with the nature, extent, and quality of the overall services provided by JSP.

of its Class A shares in comparison to a group of similar funds as selected by Broadridge (the “Performance Universe”). A fund with the best performance ranked first, and a fund with the poorest performance ranked last. The highest/best performing 25% of funds in the Performance Universe make up the first quartile; the next 25%, the second quartile; the next 25%, the third quartile; and the
poorest/worst performing 25% of funds in the Performance Universe make up the fourth quartile. Comparative annualized performance for each Fund was shown for the past 1-, 3-, 5-, and 10-year periods, to the extent, applicable, ended January 31, 2020. The Board’s objective is that the Fund’s performance for the 1-, 3-, and 5-year periods be at or above the median of its Performance Universe.

The Performance Universe for the Fund consisted of the Fund and all retail and institutional large-cap growth funds as selected by Broadridge. The Broadridge report comparison showed that the Fund’s total return for the 1-, 3-, 5-, and 10-year periods was in the fourth quartile of its Performance Universe. The Board noted that the Fund’s performance was not in line with the Board’s objective. In evaluating the Fund’s performance, the Board considered the performance attribution included in the Meeting materials, as well as the numerous investment and performance reports delivered by Management personnel to the Board’s Investments Committee. The Board was satisfied that Management was taking action to improve Fund performance and meet the Board’s performance objective.

The expense comparisons for the Fund showed that its actual management fee was in the quartile with the lowest expenses of its Expense Group and its total expenses were in the quartile with the second highest expenses of its Expense Group. The Board noted that the Fund’s total expenses were not in line with the Board’s objective. In evaluating the total expenses, the Board considered fee waivers in place through March 2021 and various initiatives implemented by Management, such as the negotiation of lower fees for fund accounting, fund accounting oversight services, and custody, which had created an opportunity for a further reduction in expenses. The Board was satisfied with Management’s efforts to improve the Fund’s total expense ratio and to bring it in line with the Board’s objective.

Management profitability. The Board considered the level of profits realized by DMC in connection with the operation of the Fund. In this respect, the Board reviewed the Investment Management Profitability Analysis that addressed the overall profitability of DMC’s business in providing management and other services to each of the individual funds and the Delaware Funds as a whole. Specific attention was given to the methodology used by DMC in allocating costs for the purpose of determining profitability.

Delaware U.S. Growth Fund

Board consideration of Investment Advisory and Sub-Advisory Agreements for Delaware U.S. Growth Fund at a meeting held August 11-13, 2020 (continued)

Management stated that the level of profits of DMC, to a certain extent, reflects recent operational cost savings and efficiencies initiated by DMC. The Board considered DMC’s efforts to improve services provided to Fund shareholders and to meet additional regulatory and compliance requirements resulting from recent industry-wide Securities and Exchange Commission initiatives. The Board also considered the extent to which DMC 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 service provider to the Delaware Funds and the benefits from allocation of fund brokerage to improve trading efficiencies. As part of its work, the Board also reviewed a report prepared by JDL regarding MIMBT profitability as compared to certain peer fund complexes and the Independent Trustees met with JDL personnel to discuss DMC’s profitability in such context. The Board found that the management fees were reasonable in light of the services rendered and the level of profitability of DMC.

Management profitability. Trustees were also given available information on profits being realized by JSP in relation to the services being provided to the Fund and in relation to JSP’s overall investment advisory business, but believed such information to be of limited relevance because the sub-advisory fees are paid by DMC out of its management fee, and changes in the level of sub-advisory fees have no impact on Fund expenses. The Board was also provided information on potential fall-out benefits derived or to be derived by JSP in connection with its relationship to the Fund, such as reputational enhancement, soft dollar arrangements, or commissions paid to affiliated broker/dealers, as applicable.

Economies of scale. The Trustees considered whether economies of scale are realized by DMC as the Fund’s assets increase and the extent to which any economies of scale are reflected in the level of management fees charged. The Trustees reviewed the Fund’s advisory fee pricing and structure, approved by the Board and shareholders, which includes breakpoints, and which applies to most funds in the Delaware Funds complex. Breakpoints in the advisory fee occur when the advisory fee rate is reduced on assets in excess of specified levels. 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 are exceeded. The Board noted that, as of March 31, 2020, the Fund’s net assets exceeded the third breakpoint level. The Board believed that, given the extent to which economies of scale might be realized by DMC and its affiliates, the schedule of fees under the Investment Management Agreement provides a sharing of benefits with the Fund and its shareholders.
