Disclosure of Fund expenses

For the six-month period from April 1, 2020 to September 30, 2020 (Unaudited)

The Fund seeks total return to the extent consistent with a relatively low volatility of principal.

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 April 1, 2020 to September 30, 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 table are meant to highlight your ongoing costs only and
do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. The Fund’s expenses shown in the table reflect
fee waivers in effect and assume reinvestment of all dividends and distributions.

Notes to financial statements

Delaware Investments Ultrashort Fund

September 30, 2020 (Unaudited)

Delaware Group^® Cash Reserve (Trust) is organized as a Delaware statutory trust and offers one series, Delaware Investments Ultrashort 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 L, and Institutional Class shares. Class A shares are sold with a maximum front-end sales charge of 2.00%. Class L and Institutional Class shares are not subject to a sales charge and are offered for sale exclusively to certain eligible investors. Class C shares are sold with a contingent deferred sales charge (CDSC) of 1.00%, which will be incurred if redeemed during the first 12 months.

1. Significant Accounting Policies

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

Security Valuation — Debt securities are valued based upon valuations provided by an independent pricing service or broker 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. 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 Income Taxes — No provision for federal income taxes has been made as the Fund
intends to continue to qualify for federal income tax purposes as a regulated investment company
under Subchapter M of the Internal Revenue Code of 1986, as amended, and make the requisite distributions to shareholders. The Fund evaluates tax positions taken or expected to be taken in the course of preparing the Fund's tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are recorded as a tax benefit or expense in the current year. Management has analyzed the Fund's tax positions taken or expected to be taken on the Fund's federal income tax returns through the six months ended September 30, 2020 and for all open tax years (years ended March 31, 2017–March 31, 2020), and has concluded that no provision for federal income tax is required in the Fund's financial statements. If applicable, the Fund recognizes interest accrued on unrecognized tax benefits in interest expense and penalties in "Other" on the “Statement of operations.” During the
six months ended September 30, 2020, the Fund did not incur any interest or tax penalties.

Table of Contents

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 each Fund on the basis of daily net assets of each class. Distribution expenses relating to a specific class are charged directly to that class.

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. 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. The Fund declares dividends daily from net investment income and pays the dividends monthly and declares and pays distributions from net realized gain on investments, if any, 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.” There were no such earnings credits for the six months ended September 30, 2020.

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 six months ended September 30, 2020, the Fund earned $269 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 0.30% on average daily net assets of the Fund.

Delaware Investments Ultrashort Fund

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

(continued)

DMC has contractually agreed to waive all or a portion of its investment advisory fees and/or
pay/reimburse expenses (excluding any distribution and service (12b-1) fees, 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) in order to prevent total annual fund operating expenses from exceeding 0.40% of the Fund’s average daily net assets from
April 1, 2020 through September 30, 2020.* These waivers and reimbursements may be terminated only by agreement of DMC and the Fund.

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 net asset value (NAV) basis. This amount is included on the “Statement of operations” under “Accounting and administration expenses.” For the six months ended September 30, 2020, the Fund was charged $3,286 for these services.

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 (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.

DIFSC is also the transfer agent and dividend disbursing agent of the Fund. For these services, DIFSC’s fees are calculated daily and paid monthly based on the aggregate daily net assets of the retail funds within the Delaware Funds at the following annual rates: 0.014% of the first $20 billion; 0.011% of the next $5 billion; 0.007% of the next $5 billion; 0.005% 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 six months ended September 30, 2020 the Fund was charged $3,552 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

Table of Contents

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, and 1.00% of the average daily net assets of the Class C shares. The fees are calculated daily and paid monthly. Class L and Institutional Class shares do not pay 12b-1 fees. DDLP has contracted to limit
the 12b-1 fees to 0.00% of average daily net assets for Class A and Class C shares from
April 1, 2020 through September 30, 2020.*

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 six months ended September 30, 2020, the Fund was charged $1,212 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 six months ended September 30, 2020, DDLP earned $477 for commissions on sales of the Fund’s Class A shares. For the six months ended September 30, 2020 , DDLP received gross CDSC commissions of $11 and $987 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.

Cost of investments	$79,956,963
Aggregate unrealized appreciation of investments	$308,459
Aggregate unrealized depreciation of investments	(83,195)
Net unrealized appreciation of investments	$225,264

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)

Table of Contents

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

The following table summarizes the valuation of the Fund’s investments by fair value hierarchy levels as of September 30, 2020:

	Level 2
Securities
Assets:
Commercial Paper	$7,049,453
Corporate Bonds	28,957,843
Non-Agency Asset-Backed Securities	43,336,394
Non-Agency Collateralized Mortgage Obligations	838,537
Total Value of Securities	$80,182,227

During the six months ended September 30, 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 into or out of Level 3 investments based on fair value at the beginning of the reporting period.

A reconciliation of Level 3 investments is presented when the Fund has a significant amount of Level 3 investments at the beginning, interim, or end of the period in relation to the Fund's net assets. During the six months ended September 30, 2020, there were no Level 3 investments.

5. Line of Credit

The Fund, along with certain other funds in the Delaware Funds (Participants), was a participant in a $220,000,000 revolving line of credit intended to be used for temporary or emergency purposes as an additional source of liquidity to fund redemptions of investor shares. On November 4, 2019, the

Table of Contents

Participants entered into an amendment to the agreement for $250,000,000 revolving line of credit (Agreement). 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 line of credit available under the Agreement expired on
November 4, 2019.

The Fund had no amounts outstanding as of September 30, 2020, or at any time during the period then ended.

6. Credit and Market Risks

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

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 potential 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 is subject to prepayment risk, which is the risk that the principal on mortgage-backed or asset-backed securities may be prepaid at any time, which will reduce the yield and market value.

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

The Fund may invest up to 5% 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 (Act), 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. The Fund may also invest in securities exempt from registration under Section 4(2) of the Act, which exempts from registration transactions by an issuer not involving any public offering. Securities eligible for resale pursuant to Rule 144A, which are determined to be liquid, are not subject to the Fund’s 5% limit on investments in illiquid securities. Rule 144A securities have been identified on the “Schedule of investments.”

7. 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.

8. Recent Accounting Pronouncements

In August 2018, FASB issued 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. Management has implemented ASU 2018-13 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.

9. Subsequent Events

On November 2, 2020, the Fund, along with the other Participants, entered into an amendment to the agreement for a $225,000,000 revolving line of credit to be used as described in Note 5 and to be operated in substantially the same manner as the agreement described in Note 5. Under the amendment to the agreement, the Participants are charged an annual commitment fee of 0.15%, which is allocated across the Participants based on a weighted average of the respective net assets of each Participant. The line of credit available under the agreement expires on November 1, 2021.

Management has determined that no other material events or transactions occurred subsequent to
September 30, 2020, that would require recognition or disclosure in the Fund's financial statements.

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. The Fund’s HLIM is set at an appropriate level and the Fund complied with its HLIM at all times during the reporting period.

Board consideration of Investment Advisory and Sub-Advisory Agreements for Delaware Investments Ultrashort 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 Investments Ultrashort 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 Europe Limited (“MIMEL”), Macquarie Investment Management Global Limited (“MIMGL”), 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 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

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

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 of the Sub-Advisers 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 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 the 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 ultrashort obligation 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 and since inception periods was in the second quartile and third quartile, respectively, 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

Table of Contents

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 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.

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. 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 Sub-Adviser 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 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, due to the unique nature of investing in ultrashort obligations, the fee under the Fund’s management contract did not fall within the standardized fee pricing structure. The Board also noted that, although, as of March 31, 2020, the Fund had not reached a size at which it could take advantage of any breakpoints in the applicable fee schedule, the Board recognized that the fee was structured so that, if the Fund increases sufficiently in size, then economies of scale may be shared.

¹On May 20, 2020, the Board of Trustees approved the replacement of the Fund’s current sub-advisor with the US Growth Equity team of the Fund’s investment manager, Delaware Management Company. In connection with this determination, the Board approved certain changes to the Fund’s investment strategies. These portfolio management and strategy changes were effective July 31, 2020. The investment strategy changes may result in higher portfolio turnover in the near term, as the new portfolio management team purchases and sells securities to accommodate the investment strategy changes. A higher portfolio turnover is likely to cause the Fund to realize capital gains and incur transaction costs. You should consult your financial advisor about the changes that will result from the investment strategy changes.

³On May 20, 2020, the Board of Trustees unanimously voted and approved a proposal to liquidate and dissolve Delaware Government Cash Management Fund (“Fund”). The liquidation and dissolution are expected to take effect on or about December 4, 2020. The Fund closed to new investors and all sales efforts ceased as of the close of business on Thursday, July 2, 2020. However, the Fund will continue to accept purchases from existing shareholders (including reinvested dividends or capital gains) until close of business Wednesday, December 2, 2020. Until the liquidation, shareholders of the Fund will have the opportunity to exchange their shares for shares of the same class of any other Delaware Funds^® by Macquarie fund. Any exchange would be made at the current net asset value of the Fund and the selected Delaware Fund. The Fund’s shareholders would not incur front-end or contingent deferred sales charges upon these exchanges as the funds do not typically carry loads or sales charges.

⁴On August 12, 2020, the Board of Trustees approved the reorganizations (together, the “Reorganizations”) of each of Delaware Tax-Exempt Income Fund, Delaware Tax-Exempt Opportunities Fund, Delaware Tax-Free California II Fund, and Delaware Tax-Free New York II Fund (collectively, the “Acquired Funds”) into and with Delaware Tax-Free USA Intermediate Fund, Delaware Tax-Free USA Fund, Delaware Tax-Free California Fund, and Delaware Tax-Free New York Fund, respectively (collectively, the “Acquiring Funds”). Effective as of the close of business on November 13, 2020, the Acquired Funds will be closed to new investors. It is anticipated that the Acquired Funds’ shareholders will receive a prospectus/information statement in October 2020 providing them with information about the Reorganizations and
the Acquiring Funds. The Reorganizations are expected to take place in December 2020. The Acquired Funds will
continue to accept purchases (including reinvested dividends and capital gains) from existing shareholders until November 25, 2020. Contingent deferred sales charges will be waived on redemptions from the Acquired Funds
through the date of the Reorganizations.

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.
