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

The examples are based on an investment of $1,000 invested at the beginning of the period and held for the entire six-month period from April 1, 2023 to September 30, 2023.

Actual Expenses

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

Hypothetical Example for Comparison Purposes

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

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

*“Expenses Paid During Period” are equal to the relevant Fund's annualized expense ratio, multiplied by the average account value over the period, multiplied by 183/366 (to reflect the one-half year period).

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

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

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

See Note 5 in “Notes to financial statements.”

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

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 $(595,792).

⁵

Markit’s iTraxx Europe Subordinated Financials Index, or the ITRX EUR SUB FIN, is comprised of 25 Financial entities from the Markit iTraxx^®Europe Index referencing subordinated debt.

⁶

Markit’s North America Investment Grade Index, or the CDX.NA.IG Index, is composed of 125 liquid North American entities with investment grade credit ratings that trade in the CDS market.

⁷

Markit’s CMBX Index, or the CMBX.NA Index, is a synthetic tradable index referencing a basket of 25 commercial mortgage-backed securities in North America. Credit-quality rating are measured on a scale that generally ranges from AAA (highest) to BB (lowest). US Agency and US Agency mortgage-backed securities appear under US Government.

⁸

An IRS agreement is an exchange of interest rates between counterparties. Periodic payments (receipt) 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 (losses) on swap contracts.

Optimum Fund Trust

September 30, 2023 (Unaudited)

Optimum Fund Trust (Trust) is organized as a Delaware statutory trust and offers 6 series: Optimum Fixed Income Fund, Optimum International Fund, Optimum Large Cap Growth Fund, Optimum Large Cap Value Fund, Optimum Small-Mid Cap Growth Fund, and Optimum Small-Mid Cap Value Fund, (each, a Fund, or collectively, the Funds). The Trust is an open-end investment company. Each Fund is considered diversified under the Investment Company Act of 1940, as amended (1940 Act), and offers Class A, Class C, and Institutional Class shares. Class A shares are sold with a maximum front-end sales charge of 4.50% for Optimum Fixed Income Fund and 5.75% for Optimum International Fund, Optimum Large Cap Growth Fund, Optimum Large Cap Value Fund, Optimum Small-Mid Cap Growth Fund, and Optimum Small-Mid Cap Value Fund. Class C shares have no upfront sales charge, but are sold with a contingent deferred sales charge (CDSC) of 1.00%, which will be incurred if redeemed during the first 12 months. Institutional Class shares are not subject to a sales charge and are offered for sale exclusively to certain eligible investors.

1. Significant Accounting Policies

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

Security Valuation — Equity securities and exchange-traded funds (ETFs), except those traded on the Nasdaq Stock Market LLC (Nasdaq), are valued at the last quoted sales price as of the time of the regular close of the New York Stock Exchange on the valuation date. Equity securities and ETFs traded on the Nasdaq are valued in accordance with the Nasdaq Official Closing Price, which may not be the last sales price. If, on a particular day, an equity security or ETF does not trade, the mean between the bid and the ask prices will be used, which approximates fair value. Equity securities listed on a foreign exchange are normally valued at the last quoted sales price on the valuation date. US government and agency securities are valued at the mean between the bid and the ask prices, which approximates fair value. Open-end investment companies, other than ETFs, are valued at their published net asset value (NAV). Fixed income securities, credit default swap (CDS) contracts, interest rate swap contracts (IRS), CDS and IRS options contracts (swaptions) are generally priced based upon valuations provided by an independent pricing service or broker/counterparty in accordance with methodologies included within Delaware Management Company (DMC)'s Pricing Policy (the Policy). Fixed income security valuations are then reviewed by DMC as part of its duties as each Fund’s valuation designee and, to the extent required by the Policy and applicable regulation, fair valued consistent with the Policy. To the extent current market prices are not available, the pricing service may take into account developments related to the specific security, as well as transactions in comparable securities. Valuations for fixed income securities 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 (CMOs), commercial mortgage securities, and US government agency mortgage securities, pricing vendors utilize matrix pricing which considers prepayment speed, attributes of the collateral, yield or price of bonds of comparable quality, coupon, maturity, and type as well as broker/dealer-supplied prices. Swap prices are derived using daily swap curves and models that incorporate a number of market data factors, such as discounted cash flows, trades, and values of the underlying reference instruments. Forward foreign currency exchange contracts are valued at the mean between the bid and the ask prices, which approximates fair value. Interpolated values are derived when the settlement date of the contract is an interim date for which quotations are not available. Futures contracts and options on futures contracts are valued at the daily quoted settlement prices. 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 the ask prices, which approximates fair value. Investments in repurchase agreements are generally valued at par, which approximates fair value, each business day. Generally, other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by DMC. Subject to the oversight of the Trust's Board of Trustees (Board), DMC, as valuation designee, has adopted policies and procedures to fair value securities for which market quotations are not readily available consistent with the requirements of Rule 2a-5 under the 1940 Act. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures or suspension of trading in a security. Restricted securities and private placements are valued at fair value.

Federal and Foreign Income Taxes — No provision for federal income taxes has been made as each Fund intends to continue to qualify for federal income tax purposes as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended, and make the requisite distributions to shareholders. Each Fund evaluates tax positions taken or expected to be taken in the course of preparing each Fund's tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are recorded as a tax benefit or expense in the current year. Management has analyzed each Fund’s tax positions taken or expected to be taken on each Fund’s federal income tax returns through the six months

Optimum Fund Trust

1. Significant Accounting Policies (continued)

ended September 30, 2023, and for all open tax years (years ended March 31, 2020–March 31, 2023), and has concluded that no provision for federal income tax is required in each Fund’s financial statements. In regard to foreign taxes only, each Fund has open tax years in certain foreign countries in which it invests that may date back to the inception of each Fund. If applicable, each Fund recognizes interest accrued on unrecognized tax benefits in interest expense and penalties in “Other” on the “Statements of operations.” During the six months ended September 30, 2023, the Funds 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 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.

Repurchase Agreements — Each 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 each 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 September 28, 2023 and September 29, 2023 and matured by October 2, 2023 and October 3, 2023, respectively.

Reverse Repurchase Agreements — Optimum Fixed Income Fund may enter into reverse repurchase agreements. In a reverse repurchase agreement, the Fund sells securities to a bank or broker/dealer and agrees to repurchase the securities at an agreed upon date and price. The Fund will maintain in a segregated account, cash, cash equivalents, or US government securities in an amount sufficient to cover its obligations under reverse repurchase agreements with broker/dealers (but no collateral is required on reverse repurchase agreements with banks). The Fund will subject its investments in reverse repurchase agreements to the borrowing provisions set forth in the 1940 Act. The use of reverse repurchase agreements by the Fund creates leverage, which increases the Fund’s investment risk. If the income and gains on securities purchased with the proceeds of reverse repurchase agreements exceed the costs of the agreements, the Fund’s earnings or NAV will increase faster than otherwise would be the case; conversely, if the income and gains fail to exceed the costs, earnings or NAV would decline faster than otherwise would be the case. For the six months ended September 30, 2023, the Fund had average reverse repurchase agreements of $948 for which it paid interest at an average rate of (30.78%). There were no reverse repurchase agreements open at the six months ended September 30, 2023.

Short Sales — Optimum Large Cap Value Fund may make short sales in an attempt to protect against declines in an individual security or the overall market, to manage duration, or for such other purposes consistent with the Fund’s investment objective and strategies. Typically, short sales are transactions in which the Fund sells a security it does not own and, at the time a short sale is effected, the Fund incurs an obligation to replace the security borrowed at whatever its price may be at the time the Fund purchases it for delivery to the lender. The price at such time may be more or less than the price at which the security was sold by the Fund. When a short sale transaction is closed out by delivery of the security, any gain or loss on the transaction generally is taxable as short-term capital gain or loss. Until the security is replaced, the Fund is required to pay the lender amounts equal to any dividends or interest that accrue during the period of the loan. To borrow the security, the Fund also may be required to pay a premium, which would increase the cost of the security sold. The proceeds of the short sale, and potentially additional margin, will be retained by the broker from whom the security is borrowed, to the extent necessary to meet margin requirements, until the short position is closed out. There were no short sales for the six months ended September 30, 2023.

Mortgage Dollar Rolls — Optimum Fixed Income Fund entered into mortgage dollar rolls in which the Fund sells mortgage securities for delivery in the current month, realizing a gain (loss), and simultaneously enter into contracts to repurchase somewhat similar (same type, coupon and maturity) securities on a specified future date. During the roll period, the Fund forgo principal and interest paid on the securities. The Fund is compensated by the interest earned on the cash proceeds of the initial sale and by the lower repurchase price at the future date. The difference between the sale proceeds and the lower repurchase price is recorded as a realized gain on investment transactions. The Fund maintains a segregated account, the dollar value of which is at least equal to its obligations, with respect to dollar rolls. The Fund is subject to the risk that the market value of the securities the Fund is obligated to repurchase under the agreement may decline below the repurchase price. The Fund is subject to leverage risk on certain transactions, such as the loans of portfolio securities, and the use of when issued or delayed delivery transactions or derivative instruments, may give rise to leverage, magnifying gains and losses and causing the Fund to be more volatile than if it had not been leveraged. The use of such transactions entails a heightened risk of loss.

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

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

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

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

Other — Expenses directly attributable to a Fund are charged directly to that Fund. Other expenses common to various funds within the Trust are generally allocated among such funds on the basis of average net assets. Management fees and certain other expenses are paid monthly. Security transactions are recorded on the date the securities are purchased or sold (trade date) for financial reporting purposes. Costs used in calculating realized gains and losses on the sale of investment securities are those of the specific securities sold. Dividend income is recorded on the ex-dividend date and interest income is recorded on an accrual basis. Income and capital gain distributions from any investment companies (Underlying Funds) in which the Funds invest are recorded on the ex-dividend date. Discounts and premiums on debt securities are accreted or amortized to interest income, respectively, over the lives of the respective securities using the effective interest method. Premiums on callable debt securities are amortized to interest income to the earliest call date using the effective interest method. Realized gains (losses) on paydowns of asset- and mortgage-backed securities are classified as interest income. 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. Foreign dividends are also recorded on the ex-dividend date or as soon after the ex-dividend date that the Funds are aware of such dividends, net of all tax withholdings, a portion of which may be reclaimable. Withholding taxes and reclaims on foreign dividends and interest have been recorded in accordance with the Funds’ understanding of the applicable country’s tax rules and rates. Each 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. Each Fund declares and pays distributions from net investment income and net realized gain on investments, if any, at least annually. Each Fund may distribute more frequently, if necessary for tax purposes. Dividends and distributions, if any, are recorded on the ex-dividend date.

Optimum Fund Trust

1. Significant Accounting Policies (continued)

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

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

DMC, a series of Macquarie Investment Management Business Trust, furnishes investment management services to each Fund and has full discretion and responsibility, subject to the overall supervision of the Board, to select and contract with one or more investment sub-advisors to manage the investment operations and composition of each Fund, and to render investment advice for each Fund, including the purchase, retention, and dispositions of investments, securities, and cash contained in each Fund. The investment management agreement obligates DMC to implement decisions with respect to the allocation or reallocation of each Fund’s assets among one or more current or additional sub-advisors, and to monitor the sub-advisors’ compliance with the relevant Fund’s investment objective, policies and restrictions. DMC pays the sub-advisors out of its fees, which are calculated daily and paid monthly.

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

Level 1 -	Inputs are quoted prices in active markets for identical investments. (Examples: equity securities, open-end investment companies, futures contracts, and exchange-traded options contracts)
Level 2 -	Other observable inputs, including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks, and default rates) or other market-corroborated inputs. (Examples: debt securities, government securities, swap contracts, forward foreign currency exchange contracts, foreign securities utilizing international fair value pricing, broker-quoted securities, and fair valued securities)
Level 3 -	Significant unobservable inputs, including each Fund's own assumptions used to determine the fair value of investments. (Examples: broker-quoted securities and fair valued securities)

Level 3 investments are valued using significant unobservable inputs. Each Fund may also use an income-based valuation approach in which the anticipated future cash flows of the investment are discounted to calculate fair value. Discounts may also be applied due to the nature or duration of any restrictions on the disposition of the investments. Valuations may also be based upon current market prices of securities that are

comparable in coupon, rating, maturity, and industry. The derived value of a Level 3 investment may not represent the value which is received upon disposition and this could impact the results of operations.

As a result of utilizing international fair value pricing at September 30, 2023, a portion of Optimum International Fund’s common stock investments were categorized as Level 2.

During the six months ended September 30, 2023, there were no transfers into or out of Level 3 investments. Each Fund's policy is to recognize transfers into or out of Level 3 investments based on fair value at the beginning of the reporting period.

A reconciliation of Level 3 investments is presented when a Fund has a significant amount of Level 3 investments at the beginning or end of the period in relation to that 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 each Fund’s net assets at the beginning or end of the period. Management has determined not to provide additional disclosure on Level 3 inputs since the Level 3 investments were not considered significant to each Fund’s net assets at the end of the period. As of September 30, 2023, Optimum Large Cap Value Fund and Optimum Small-Mid Cap Value Fund had no Level 3 investments.

5. Derivatives

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

Forward Foreign Currency Exchange Contracts — Each Fund may enter into forward foreign currency exchange contracts and forward foreign cross currency exchange contracts as a way of managing foreign exchange rate risk. Each 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. Each Fund may also enter into these contracts to hedge the US dollar value of securities it already owns that are denominated in foreign currencies. In addition, each Fund may enter into these contracts to facilitate or expedite the settlement of portfolio

transactions. The change in value is recorded as an unrealized gain or loss. When the contract is closed, a realized gain or loss is recorded equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed.

The use of forward foreign currency exchange contracts and forward 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 forward foreign currency exchange contracts and forward 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, each Fund could be exposed to risks if the counterparties to the contracts are unable to meet the terms of their contracts. Each 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 Funds and the counterparty and by the posting of collateral by the counterparty to the Funds to cover the Funds’ exposure to the counterparty. Open forward foreign currency exchange contracts, if any, are disclosed on the “Schedules of investments.”

During the six months ended September 30, 2023, Optimum Fixed Income Fund and Optimum Large Cap Growth Fund each used forward foreign currency exchange contracts to hedge the US dollar value of securities it already owns that are denominated in foreign currencies to decrease exposure to foreign currencies.

Futures Contracts — A futures contract is an agreement in which the writer (or seller) of the contract agrees to deliver to the buyer an amount of cash or securities equal to a specific dollar amount times the difference between the value of a specific security or index at the close of the last trading day of the contract and the price at which the agreement is made. Optimum Fixed Income Fund may use futures contracts in the normal course of pursuing its investment objective. Optimum Fixed Income 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. The Fund posted securities collateral valued at $3,057,803 and $12,595,000 cash collateral as margin for open futures contracts. Cash collateral is included as “Cash collateral due from brokers” on the “Statements of assets and liabilities” and securities collateral are presented on the “Schedules of investments.” Open futures contracts, if any, are disclosed on the “Schedules of investments.”

During the six months ended September 30, 2023, Optimum Fixed Income Fund used futures contracts to hedge the Fund’s existing portfolio securities against fluctuations in value caused by changes in interest rates or market conditions, as a cash management tool, and to facilitate investments in portfolio securities.

Options Contracts — Optimum Fixed Income 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.

Table of Contents

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. Open options contracts, if any, are disclosed on the “Schedules of investments.”

During the six months ended September 30, 2023, Optimum Fixed Income Fund used options contracts to manage the Fund’s exposure to changes in securities prices caused by interest rates or market conditions, to manage the Fund’s exposure to changes in foreign currencies, to adjust the Fund’s overall exposure to certain markets, to receive premiums for writing options, and to protect the value of portfolio securities.

Swap Contracts — Optimum Fixed Income Fund may enter into currency swap contracts, index swap contracts, inflation swaps, IRS contracts, and CDS contracts in the normal course of pursuing its investment objective. The Fund may invest in IRS contracts to manage the Fund’s sensitivity to interest rates or to hedge against changes in interest rates. The Fund may use currency swaps to protect against currency fluctuations. The Fund may use inflation swaps to hedge the inflation risk in nominal bonds, thereby creating synthetic inflation-indexed bonds. 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. Swap agreements are bilaterally negotiated agreements between a Fund and counterparty to exchange or swap investment cash flows, assets, foreign currencies or market-linked returns at specified, future intervals. Swap agreements are privately negotiated in the over-the-counter market (OTC swaps). If the OTC swap entered is one of the swaps identified by a relevant regulator as a swap that is required to be cleared, then it will be cleared through a third party, known as a central counterparty or derivatives clearing organization (centrally cleared swaps).

Interest Rate Swaps. An IRS contract is an exchange of interest rates between counterparties. In one instance, an interest rate swap involves payments received by Optimum Fixed Income 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.

During the six months ended September 30, 2023, Optimum Fixed Income Fund used interest rate swap contracts to manage the Fund’s sensitivity to interest rates or to hedge against changes in interest rates.

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

During the six months ended September 30, 2023, Optimum Fixed Income 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.

As disclosed in the footnotes to the “Schedules of investments,” at September 30, 2023, the notional value of the protection sold was EUR 9,400,000 and USD 26,415,000, which reflects the maximum potential amount Optimum Fixed Income Fund would have been required to make as a seller of credit protection if a credit event had occurred. In addition to serving as the source of the current value of the securities, the

quoted market prices and resulting market values for credit default swap agreements on securities and credit indices serve as an indicator of the current status of the payment/performance risk and represent the likelihood of an expected liability (or profit) for the credit derivative if the swap agreement has been closed/sold as of the period end. Increasing market values, in absolute terms when compared to the notional amount of the swap, represent a deterioration of the reference entity’s credit soundness and a greater likelihood of risk of default or other credit event occurring as defined under the terms of the agreement. At September 30, 2023, there were no recourse provisions with third parties to recover any amounts paid under the credit derivative agreement (including any purchased credit protection) nor was any collateral held by the Fund and other third parties which the Fund can obtain in the occurrence of a credit event. At September 30, 2023, net unrealized appreciation of the protection sold was $880,540.

CDS contracts may involve greater risks than if Optimum Fixed Income 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, or (2) for cleared swaps, trading these instruments through a central counterparty.

During the six months ended September 30, 2023, Optimum Fixed Income Fund used 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 Optimum Fixed Income Fund as unrealized gains or losses until the contracts are closed. When the contracts are closed, Optimum Fixed Income 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 Optimum Fixed Income 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 “Schedules of investments.”

At September 30, 2023, for bilateral derivative contracts, Optimum Fixed Income Fund posted $4,277,000 cash collateral for certain centrally cleared derivatives, which is included in “Cash collateral due from brokers” on the “Statements of assets and liabilities.” The Fund also posted $8,375,860 in securities collateral comprised of US treasury obligations for certain open centrally cleared derivative contracts. At September 30, 2023, for bilateral derivative contracts, the Fund received $9,062,000 in cash collateral, which is included in “Cash collateral due to brokers” on the “Statements of assets and liabilities.” The Fund also posted $3,834,445 in securities collateral comprised of US treasury obligations for certain open bilateral derivative contracts. Securities collateral are presented on the “Schedules of investments.”

6. Offsetting

Certain Funds 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 certain Funds mitigate its counterparty risk. An ISDA Master Agreement is a bilateral agreement between certain Funds and a counterparty that governs certain over-the-counter derivatives and foreign exchange contracts and typically contains, among other things, collateral posting items and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, certain Funds 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, certain Funds do not offset derivative assets and derivative liabilities that are subject to netting arrangements on the “Statements of assets and liabilities.”

At September 30, 2023, certain Funds had the following assets and liabilities subject to offsetting provisions:

Master Repurchase Agreements

Repurchase agreements are entered into by each Fund under master repurchase agreements (each, an MRA). The MRA permits each Fund, under certain circumstances including an event of default (such as bankruptcy or insolvency), to offset payables and/or receivables with collateral held by and/or posted to the counterparty. As a result, one single net payment is created. Bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of the MRA counterparty’s bankruptcy or insolvency. Based on the terms of the MRA, each Fund receives securities as collateral with a market value in excess of the repurchase price at maturity. Upon a bankruptcy or insolvency of the MRA counterparty, each Fund would recognize a liability with respect to such excess collateral. The liability reflects each Fund's obligation under bankruptcy law to return the excess to the counterparty. As of September 30, 2023, the following table is a summary of each Fund's repurchase agreements by counterparty which are subject to offset under an MRA:

	Optimum Fixed Income Fund
Counterparty	Reverse Repurchase Agreements		Fair Value of Non-Cash Collateral Received			Cash Collateral Received^(a)		Net Collateral Received			Net Exposure^(b)
BNP Paribas	$	130,500,000	$	(130,500,000	)	$	—	$	(130,500,000	)	$	—

^(a)The value of the related collateral exceeded the value of the derivatives, repurchase agreements, and securities lending transactions as of September 30, 2023, as applicable.
^(b)Net exposure represents the receivable (payable) that would be due from (to) the counterparty in the event of default.

7. Securities Lending

Each Fund, along with other funds in the Delaware Funds, may lend its securities pursuant to a security lending agreement (Lending Agreement) with The Bank of New York Mellon (BNY Mellon). At the time a security is loaned, the borrower must post collateral equal to the

124

Table of Contents

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

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

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

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

At September 30, 2023, each Fund had no securities out on loan.

8. Credit and Market Risks

The global outbreak of COVID-19 resulted in travel restrictions, closed international borders, enhanced health screenings at ports of entry and elsewhere, disruption of and delays in healthcare service preparation and delivery, prolonged quarantines, cancellations, supply chain disruptions, and lower consumer demand, as well as general concern and uncertainty. The impact of COVID-19, and other infectious illness outbreaks that may arise in the future, could adversely affect the economies of many nations or the entire global economy, individual issuers and capital markets in ways that cannot necessarily be foreseen. In addition, the impact of infectious illnesses in emerging market countries may be greater due to generally less established healthcare systems. Public health crises caused by the COVID-19 outbreak may exacerbate other pre-existing political, social and economic risks in certain countries or globally. The duration of the outbreak, its full economic impact and ongoing effects at the macro-level and on individual businesses are unpredictable and may result in significant and prolonged effects on a Fund’s performance.

Beginning in late February 2022, global financial markets have experienced and may continue to experience significant volatility related to military action by Russia in Ukraine. As a result of this military action, the US and many other countries have imposed sanctions on Russia and

certain Russian individuals, banks and corporations. The ongoing hostilities and resulting sanctions are expected to have a severe adverse effect on the region’s economies and more globally, including significant negative impact on markets for certain securities and commodities, such as oil and natural gas. Any cessation of trading on the Russian securities markets will impact the value and liquidity of certain portfolio holdings. The extent and duration of military action, sanctions, and resulting market disruptions are impossible to predict, but could be substantial and prolonged and impact your Funds' performance.

Investments in equity securities in general are subject to market risks that may cause their prices to fluctuate over time. Fluctuations in the value of equity securities in which the Funds invest will cause the NAV of the Funds to fluctuate.

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

The securities exchanges of certain foreign markets are substantially smaller, less liquid, and more volatile than the major securities markets in the US. Consequently, acquisition and disposition of securities by the Funds 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 Funds.

When interest rates rise, fixed income securities (i.e. debt obligations) generally will decline in value. These declines in value are greater for fixed income securities with longer maturities or durations. Interest rate changes are influenced by a number of factors, such as government policy, monetary policy, inflation expectations, and the supply and demand of bonds. A Fund may be subject to a greater risk of rising interest rates when interest rates are low or inflation rates are high or rising.

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

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

As Optimum Fixed Income Fund may be required to rely upon another lending institution to collect and pass on to the Fund amounts payable with respect to the loan and to enforce the Fund’s rights under the loan and other direct indebtedness, an insolvency, bankruptcy, or reorganization of the lending institution may delay or prevent the Fund from receiving such amounts. The highly leveraged nature of many loans may make them especially vulnerable to adverse changes in economic or market conditions. Investments in such loans and other direct indebtedness may involve additional risk to the Fund. There were no unfunded loan commitments at the six months ended September 30, 2023.

Optimum Fixed Income 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

126

Table of Contents

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.

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

Optimum Small-Mid Cap Growth Fund and Optimum Small-Mid Cap Value Fund invest a significant portion of their assets in small- and mid-sized companies and may be subject to certain risks associated with ownership of securities of such companies. Investments in small- and mid-sized companies may be more volatile than investments in larger companies for a number of reasons, which include more limited financial resources or a dependence on narrow product lines.

Optimum Large Cap Growth Fund, Optimum Large Cap Value Fund, Optimum Small-Mid Cap Growth Fund, and Optimum Small-Mid Cap Value Fund may invest in REITs and are subject to the risks associated with that industry. If a Fund holds real estate directly or receives rental income directly from real estate holdings, its tax status as a regulated investment company may be jeopardized. There were no direct real estate holdings during the six months ended September 30, 2023. The Funds’ REIT holdings are also affected by interest rate changes, particularly if the REITs they hold use floating rate debt to finance their ongoing operations. The Funds also invest in real estate acquired as a result of ownership of securities or other instruments, including issuers that invest, deal, or otherwise engage in transactions in real estate or interests therein. These instruments may include interests in private equity limited partnerships or limited liability companies that hold real estate investments (Real Estate Limited Partnerships). The Funds will limit their investments in Real Estate Limited Partnerships to 5% of their total assets at the time of purchase.

Optimum Large Cap Growth Fund, Optimum Large Cap Value Fund, and Optimum Small-Mid Cap Growth 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.

Each Fund may invest up to 15% of its net assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A promulgated under the Securities Act of 1933, as amended (1933 Act), and other securities which may not be readily marketable. The Funds may also invest in securities exempt from registration under Section 4(a)(2) of the 1933 Act, which exempts from registration transactions by an issuer not involving any public offering. The relative illiquidity of these securities may impair each Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. While maintaining oversight, the Trust’s Board has delegated to DMC, the day-to-day functions of determining whether individual securities are liquid for purposes of the Funds’ limitation on investments in illiquid securities. Securities eligible for resale pursuant to Rule 144A, which are determined to be liquid, are not subject to the Funds’ 15% limit on investments in illiquid securities. Rule 144A and restricted securities have been identified on the “Schedules of investments.”

9. Contractual Obligations

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

Liquidity Risk Management Program

The Securities and Exchange Commission (the “SEC”) has adopted Rule 22e-4 under the Investment Company Act of 1940 (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 the fund’s “liquidity risk,” defined as the risk that the fund could not meet requests to redeem shares issued by the fund without significant dilution of remaining investors’ interests in the fund.

The Funds have adopted and implemented a liquidity risk management program in accordance with the Liquidity Rule (the “Program”). The Board has designated a member of the US Investment Risk Group of Macquarie Asset Management as the Program Administrator for each Fund in the Trust.

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 each 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 each Fund's acquisition of Illiquid investments if, immediately after the acquisition, each 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 each 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 each Fund's liquidity risk, the Program Administrator considers, as relevant, a variety of factors, including: (1) each 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 Funds during both normal and reasonably foreseeable stressed conditions; and (3) each Fund's holdings of cash and cash equivalents and any borrowing arrangements. Classification of each 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.

At a meeting of the Board held on June 22-23, 2023, 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 April 1, 2022 through March 31, 2023. The report concluded that the Program is appropriately designed and effectively implemented and that it meets the requirements of Rule 22e-4 and each Fund's liquidity needs. Each Fund's HLIM is set at an appropriate level and the Funds complied with their HLIM at all times during the reporting period.

Board Consideration of Optimum Fund Trust Investment Management and Sub-Advisory Agreements at Meeting Held September 21-22, 2023

At a meeting held Sept. 21-22, 2023 (the “Meeting”), the Board of Trustees (the “Board” or “Trustees”), including a majority of the non-interested or Independent Trustees, approved: (i) the renewal of the Investment Management Agreement between Delaware Management Company (“DMC” or “Management”) and Optimum Fund Trust (the “Trust”), on behalf of each of the six separate series within the Trust (each, a “Fund” or collectively, the “Funds”); and (ii) the continuation of Sub-Advisory Agreements for the existing sub-advisers of all the Funds, including the approval of a new Sub-Advisory Agreement between DMC and Los Angeles Capital Management LLC (“Los Angeles Capital”) in anticipation of a pending change-in-control for Los Angeles Capital as described below.

In reaching its decisions with regard to the Investment Management and Sub-Advisory Agreements, the Board took into account information furnished and discussed throughout the year at quarterly Board meetings, as well as information furnished specifically for the agreement reviews conducted at the Meeting. Information furnished at Board meetings throughout the year included an analysis by DMC (with the assistance of its consultant, LPL Financial LLC, “LPL”) of the investment performance of each Fund and its sub-adviser(s), presentations given to the Board by representatives of DMC and portfolios managers from each unaffiliated sub-adviser on a rotating basis, and compliance reports and related certifications furnished in regards to DMC and each sub-adviser. Material furnished specifically in connection with the approvals (or otherwise available to the Board) included: a memorandum from DMC discussing and analyzing the performance of each Fund and its respective sub-adviser(s); information on the fees charged by DMC and each unaffiliated sub-adviser showing their competitiveness with those

charged by them to other comparable investment companies or accounts; copies of the Investment Management and Sub-Advisory Agreements; a “due diligence” report describing various material items in relation to the personnel, organization and policies of DMC and the sub-advisers; and information on the fees received and other benefits realized by DMC (and its affiliates) and the sub-advisers in performing services for the Funds, as well as the revenues and expenses incurred by DMC and its affiliates in performing such services. Information furnished specifically in connection with the approval process also included a report for each Fund prepared by Lipper Inc. (“Lipper”), an independent third-party analyst and subsidiary of Broadridge Inc. (“Broadridge”), comparing, among other things, each Fund’s investment performance and various expenses with those of other mutual funds deemed comparable by Lipper (“Lipper Report”). In addition, DMC also provided the Board with materials describing Los Angeles Capital’s pending change-in-control due to an employee share offering that Los Angeles Capital will conduct approximately towards the end of 2023 that will cause the equity interest of one of Los Angeles Capital’s founders to drop below 25% (“Change-In-Control”).

In considering such materials, the Independent Trustees received assistance and advice from and met separately with their independent legal counsel (both prior to and at the Meeting). In this regard, the Independent Trustees reviewed with independent legal counsel their duties and obligations in connection with the approval of investment management and other agreements with DMC, its affiliates and the sub-advisers and discussed, in detail, the matters related to such approvals. The Independent Trustees also met with representatives of Broadridge at the Meeting to allow Broadridge the opportunity to expand on certain aspects of the Lipper Report.

The materials prepared by Management specifically in connection with the approval of the Investment Management Agreement and the related Sub-Advisory Agreements were provided to the Independent Trustees in advance of the Meeting. While the Investment Management Agreement and related Sub-Advisory Agreements for all Funds were considered at the Meeting, the Board dealt with each Fund separately. While attention was given to all information furnished, the following discusses some primary factors relevant to the Board’s decisions. This discussion of the information and factors considered by the Board (as well as the discussion above) is not intended to be exhaustive, but rather summarizes certain factors considered by the Board. In view of the wide variety of factors considered, the Board did not, unless otherwise noted, find it practicable to quantify or otherwise assign relative weights to the following factors. In addition, individual Trustees may have assigned different weights to various factors.

Nature, Extent and Quality of Services. Following discussions in this regard, the Trustees were satisfied with the nature, extent and quality of the services provided by DMC and its affiliates to each of the Funds. The Board’s view was based upon factors such as the background and experience of the executives and other Management personnel involved in the Funds’ operations, the quality and thoroughness of the monitoring of each Fund’s investment performance, reports furnished by DMC as to adherence with various compliance and procedural matters, such as the Code of Ethics and fair value pricing, the monitoring of various service providers to the Funds, and DMC’s success in obtaining meaningful information on a timely basis from each of the Fund’s sub-advisers. Particular attention was given to the analysis of sub-adviser performance for each Fund, including the complementary nature of investment strategies employed by the sub-advisers (and DMC with respect to the Optimum Fixed Income Fund) to each of the Funds.

In considering the nature of the services provided by Macquarie Investment Management Austria Kapitalanlage AG (“MIMAK”), Macquarie Investment Management Europe Limited (“MIMEL”), and Macquarie Investment Management Global Limited (“MIMGL”) to the Optimum Fixed Income Fund (collectively, the “Affiliated Sub-Advisers”), the Board considered that, unlike the unaffiliated sub-advisers who make all of the investment related decisions with respect to a sub-advised portfolio of a Fund, the relationship between DMC and the Affiliated Sub-Advisers on the Optimum Fixed Income Fund is currently one in which DMC may seek investment advice and recommendations from its Affiliated Sub-Advisers but that DMC retains primary responsibility for the day-to-day management of DMC’s portion of the Optimum Fixed Income Fund’s portfolio. It was also noted that, for the year ended March 31, 2023, and the period from April 1, 2023 to June 30, 2023, MIMAK and MIMGL were not paid any fees by DMC pursuant to their Sub-Advisory Agreements and that the fees paid to MIMEL were de minimis.

The nature of the services provided by the existing sub-advisers to each Fund was considered primarily in respect to the investment performance of the Funds as described further in the “Investment Performance” section below. The Board also considered the adherence by each sub-adviser (and DMC with respect to the Optimum Fixed Income Fund) with the investment policies and restrictions of the Funds advised,

130

Table of Contents

as well as their adherence to various compliance and other procedures based on reports of Management’s review of sub-adviser (and DMC with respect to the Optimum Fixed Income Fund) compliance activities, as well as certifications and materials furnished in connection with Board meetings and the contract approvals.

Based upon these considerations, the Board was satisfied with the nature, extent and quality of the overall services to be provided by the existing sub-advisers to each Fund, as applicable, and its shareholders and was confident in the abilities of these sub-advisers and DMC to provide quality services to the Funds and their shareholders.

Investment Performance. The Board placed significant emphasis on the investment performance of each Fund. While consideration was given to performance reports and discussions held throughout the year (including a detailed discussion of the investment performance of each Fund and its sub-advisers contained in a memorandum from DMC provided to the Board prior to the Meeting), particular attention in assessing performance was given to the Lipper Reports furnished in connection with the contract approvals. The Lipper Reports prepared for each individual Fund showed the annualized total return investment performance of its Institutional Class shares in comparison with a Performance Universe selected by Lipper for the one year period ended June 30, 2023, as well as the three, five and ten year periods ended on that date. In addition, the Board was provided with benchmark returns and gross performance returns for the Funds and each of their respective sub-advisers for various periods ended June 30, 2023. The Trustees also compared Fund and sub-adviser performance to other industry benchmarks and reviewed rolling thirty-six-month return rankings (relative to each Fund’s respective Morningstar peer group) for the Funds, as part of their evaluation of investment performance. The following summarizes the performance results for each Fund and the Board’s view of such performance.

Optimum Fixed Income Fund — The Lipper Performance Universe for this Fund consisted of the Fund and all retail and institutional core plus bond funds as selected by Lipper. The Lipper Report showed the Fund’s investment performance on an annualized basis to be in the middle quintile of its Performance Universe for the one year period and in the second lowest performing quintile of its Performance Universe for the three, five and ten-year periods. It was also noted that the Fund had outperformed its benchmark on a gross performance basis for the one, three, five and ten-year periods ended June 30, 2023. After further discussions with Management regarding the Fund’s performance and portfolio positioning, the Trustees found the overall comparative performance results of the Fund to be acceptable.

Optimum International Fund — The Lipper Performance Universe for this Fund consisted of the Fund and all retail and institutional international multi-cap growth funds as selected by Lipper. The Lipper Report showed the Fund’s investment performance on an annualized basis to be in the second lowest performing quintile of its Performance Universe for the one year period, in the second highest performing quintile of its Performance Universe for the three year period and in the lowest performing quintile of its Performance Universe for the five and ten-year periods. It was also noted that the Fund had outperformed its benchmark on a gross performance basis for the one, three and ten-year periods ended June 30, 2023, and it underperformed its benchmark during the five-year period. The Trustees acknowledged that this was an improvement in relative performance versus the Fund’s Performance Universe and its benchmark compared to the prior year and that this reversal was driven by the improved performance of Baillie Gifford Overseas Limited (“Baillie Gifford”) on its portion of the Fund. Although the Board was encouraged by Baillie Gifford’s outperformance during the past year and the Fund’s improved relative performance versus its benchmark, the Board noted that the Fund’s long-term relative performance lagged versus its Performance Universe and that Management would continue to monitor the Fund’s performance for signs of longer term improvement going forward.

Optimum Large Cap Growth Fund — The Lipper Performance Universe for this Fund consisted of the Fund and all retail and institutional large-cap growth funds as selected by Lipper. The Lipper Report showed the Fund’s investment performance on an annualized basis to be in the second highest performing quintile of its Performance Universe for the one-year period, in the lowest performing quintile of its Performance Universe for the three and five-year periods, and in the second lowest performing quintile of its Performance Universe for the ten-year period. It was also noted that the Fund had outperformed its benchmark for the one-year period and underperformed its benchmark on a gross performance basis for the three, five and ten-year periods ended June 30, 2023. The Trustees noted that Management recommended, and the Board approved early in 2023, Los Angeles Capital as a new sub-adviser to the Fund to be paired with American Century Investment Management, Inc. (the Fund’s other sub-adviser that was hired in July 2022) in an attempt to benefit the Fund’s performance going forward. The Trustees noted that this new sub-adviser pairing for the Fund has improved performance for the one-year period ended June 30, 2023. Although the Board was not satisfied with the longer-term comparative performance for the Fund, the Board believed that Management was taking appropriate actions to attempt to improve the Fund’s performance as evidenced by the improved Fund performance since Los Angeles Capital and American Century were hired.

Board Consideration of Optimum Fund Trust Investment Management and Sub-Advisory Agreements at Meeting Held September 21-22, 2023 (continued)

Optimum Large Cap Value Fund — The Lipper Performance Universe for this Fund consisted of the Fund and all retail and institutional large-cap value funds as selected by Lipper. The Lipper Report showed the Fund’s investment performance on an annualized basis to be in the middle performing quintile of its Performance Universe for the one, three and five-year periods, and in the second lowest performing quintile of its Performance Universe for the ten-year period. In addition, the Board noted that the Fund had outperformed its benchmark on a gross performance basis for the one, three, five and ten-year periods ended June 30, 2023. The Board found the overall comparative performance results of the Fund to be acceptable.

Optimum Small-Mid Cap Growth Fund — The Lipper Performance Universe for this Fund consisted of the Fund and all retail and institutional small-cap growth funds as selected by Lipper. The Lipper Report showed the Fund’s investment performance on an annualized basis to be in the second lowest performing quintile of its Performance Universe for the one year period, in the second highest performing quintile of its Performance Universe for the three and ten-year periods, and in the highest performing quintile of its Performance Universe for the five-year period. In addition, the Board noted that the Fund had outperformed its benchmark on a gross basis for the three, five, and ten-year periods ended June 30, 2023. The Board found the overall comparative performance results of the Fund to be satisfactory.

Optimum Small-Mid Cap Value Fund — The Lipper Performance Universe for this Fund consisted of the Fund and all retail and institutional small-cap core funds as selected by Lipper. The Lipper Report showed the Fund’s investment performance on an annualized basis to be in the lowest performing quintile of its Performance Universe for the one and ten-year periods, in the middle performing quintile of its Performance Universe for the three-year period and in the second lowest performing quintile of its Performance Universe for the five-year period. In addition, the Board noted that the Fund had underperformed its benchmark on a gross basis for the one, three, five and ten-year periods ended June 30, 2023. Management acknowledged that Cardinal Capital Management, L.L.C. (“Cardinal”) had been the primary driver of the Fund’s underperformance over the past year. Management noted that they were continuing to evaluate the Fund’s overall performance. Although the Board found the recent performance results of the Fund to be disappointing, the Board was satisfied that Management was prepared to take appropriate action as necessary in an attempt to improve Fund performance going forward.

Comparative Expenses. In considering the appropriateness of the investment management fees charged to the Funds, the Board also reviewed and considered the investment management fees in light of the nature, extent and quality of the investment management services provided, and to be provided, by DMC and each sub-adviser, as more fully discussed above. The Board noted that the sub-advisory fees are paid by DMC to each sub-adviser and are not additional fees borne by the Funds. The Board also noted that the sub-advisory fees paid, and to be paid, by DMC to each unaffiliated sub-adviser were the product of arms-length negotiations between DMC and each such sub-adviser. The Trustees considered DMC’s belief that the sub-advisory fees paid by DMC to each sub-adviser were competitive, fair and reasonable in light of the nature, extent and quality of the services furnished by each such sub-adviser to the Funds. The Board also considered the allocation of the investment management fees charged to the Funds between DMC and each sub-adviser in light of the nature, extent and quality of the investment management services provided, and to be provided by, DMC and each sub-adviser. The Trustees considered various other products, portfolios and entities that are advised by DMC and each unaffiliated sub-adviser, as applicable, as well as their relative fees and reasons for differences with respect thereto and any potential conflicts of interest.

Attention was also given to a comparative analysis of each Fund’s Institutional Class share expenses, including investment management fees, in comparison to a group of other multi-advised institutional funds constituting its Lipper Expense Universe. Lipper expense data is based upon information for the twelve months covered by each Fund’s most recent annual report which reflects historical asset levels which may be different from those currently existing, particularly in a period of market volatility. While recognizing such inherent limitations and the fact that expense ratios generally increase as assets decline and decrease as assets grow, the Trustees believed that the independent analysis conducted by Lipper remained an appropriate measure of comparative expenses. The Lipper Report rankings showed the actual total expenses (taking into account expense waivers) to be in the second highest quintile (i.e., the quintile having the second highest expenses) for the Optimum Fixed Income Fund, Optimum International Fund, Optimum Large Cap Growth Fund and the Optimum Large Cap Value Fund versus their respective Lipper Expense Universe and in the highest expense quintile for the other two Optimum Funds versus their respective Lipper Expense Universes. The Lipper Report rankings showed actual investment management fees (taking into account fee waivers) to be in the second lowest quintile for the Optimum International Fund, the middle quintile for the Optimum Large Cap Growth Fund and the Optimum Fixed Income Fund, in the second highest quintile for the Optimum Large Cap Value Fund, and in the highest quintile for the Optimum Small-Mid Cap Growth Fund and Optimum Small-Mid Cap Value Fund versus their respective Lipper Expense Universe. The Lipper Report also showed the percentile

132

Table of Contents

ranking for each Fund versus the Fund’s Expense Universe and Performance Universe on a combined basis, and it showed that the combined percentile ranking for the Funds had improved or generally stayed in line versus the prior year. The Board also considered the favorable impact of the Fee Restructuring (as defined below) on the Funds’ actual total expense ratios. The Trustees noted that such expense ratios have trended down since the Fee Restructuring and that, based on discussions with the Independent Trustees, Management would continue to explore opportunities to reduce Fund expenses in the future and provide a proposal to the Board at an upcoming meeting.

The Trustees noted that DMC, since inception, had waived fees to the extent necessary to keep expenses of each Fund from exceeding a designated percentage of the applicable Fund’s average daily net assets, and that the Trustees had also previously discussed in detail the current cap on expenses in effect for each Fund through July 29, 2023. The Trustees also noted that Management had previously agreed to various restructurings and overall reductions in fees charged to the Funds through several mechanisms, including a fee restructuring with regard to the investment management, administration and transfer agency fee schedules for each of the Funds to reduce the Funds’ total expenses going forward that became effective April 1, 2017 (the “Fee Restructuring”).

While intending to continuously monitor the fee structure of each Fund, the Trustees found the expense structure of each Fund to be acceptable in view of the nature and structure of Fund operations, and Management’s cap on expenses, and taking into account the aforementioned Fee Restructuring.

DMC’s Profitability; Economies of Scale. Based on the asset size of each Fund and the reimbursement and/or waiver of expenses by DMC, as well as other profitability information furnished to them by DMC and within the Lipper Report, the Trustees did not believe that the level of profit being realized by DMC and its affiliates from services provided to any of the Funds was excessive. Trustees were also given the information made available by the sub-advisers on profits being realized by sub-advisers in relation to the services being provided to the Funds or in relation to the sub-advisers’ overall investment advisory business, but believed such information to be of limited relevance since the fees paid to the unaffiliated sub-advisers were the product of arms-length negotiations between DMC and each such sub-adviser, and the fees paid to each sub-adviser are paid by DMC and not the Funds. The Board also took into account Management’s expenditures in improving shareholder services provided to the Funds, as well as the need to meet regulatory and compliance requirements resulting from recent SEC and other regulatory requirements. The Board was also provided with information on potential fall-out benefits derived or to be derived by DMC and its affiliates or the sub-advisers in connection with their relationship to the Funds, such as the fees received for non-investment management services provided to the Funds by certain affiliates of DMC, soft dollar arrangements, and commissions paid to affiliated broker-dealers. The Trustees recognized that as the Funds’ assets grow, economies of scale may result in DMC realizing a larger profit margin on management services provided to a Fund. The Trustees also noted that economies of scale are shared with a Fund and its shareholders through investment management fee breakpoints so that as a Fund grows in size, its effective investment management fee rate declines.

Form N-PORT and proxy voting information

Each Fund files its complete schedule of portfolio holdings with the Securities and Exchange Commission (SEC) for the first and third quarters of each fiscal year on Form N-PORT. Each Fund’s Forms N-PORT, as well as a description of the policies and procedures that the Funds use to determine how to vote proxies (if any) relating to portfolio securities, are available without charge (i) upon request, by calling 800 914-0278; and (ii) on the SEC’s website at sec.gov. In addition, a description of the policies and procedures that the Funds use to determine how to vote proxies (if any) relating to portfolio securities and the Schedule of Investments included in the Funds' most recent Form N-PORT are available without charge on the Funds’ website at optimummutualfunds.com.

Information (if any) regarding how the Funds voted proxies relating to portfolio securities during the most recently disclosed 12-month period ended June 30 is available without charge (i) through the Funds’ website at optimummutualfunds.com/shareholder/proxy-voting-information; and (ii) on the SEC’s website at sec.gov.
