Disclosure of Fund expenses

For the six-month period from April 1, 2017 to September 30, 2017 (Unaudited)

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/or service (12b-1) fees; and other Fund expenses. These 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, 2017 to Sept. 30, 2017.

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 ratios 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 a 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. Each Fund’s expenses shown in the tables reflect fee waivers in effect. The expenses shown in each table assume reinvestment of all dividends and distributions.

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

¹See Note 5 in “Notes to financial statements.”

²A 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 agreement.

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

⁴Unrealized appreciation (depreciation) does not include periodic interest payments on swap contracts accrued daily in the amount of ($616,352).

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

⁶ Markit’s Emerging markets CDX Index, or the CDX.EM Index is composed of 15 sovereign issuers from the following countries: Argentina, Brazil, Chile, China, Colombia, Indonesia, Malaysia, Mexico, Panama, Peru, Philippines, Russia, South Africa, Turkey, and Venezuela, which have S&P credit quality rating of CCC and above.

⁷Markit’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 D (lowest). US Agency and US Agency mortgage-backed securities appear under US Government.

⁸An interest rate swap 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.

1. Significant Accounting Policies

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 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. Open-end investment company securities are valued at net asset value (NAV) per share, as reported by the underlying investment company. US government and agency securities are valued at the mean between the bid and ask prices, which approximates fair value. Other debt securities, credit default swap (CDS) contracts, interest rate swap options contracts (swaptions) and interest rate swap contracts are valued based upon valuations provided by an independent pricing service or broker/counterparty and reviewed by management. To the extent current market prices are not available, the pricing service may take into account developments related to the specific security, as well as transactions in comparable securities. Valuations for fixed income securities utilize matrix systems, which reflect such factors as security prices, yields, maturities, and ratings, and are supplemented by dealer and exchange quotations. For asset-backed securities, collateralized mortgage obligations, commercial mortgage securities, and US government agency mortgage securities, pricing vendors utilize matrix pricing which considers prepayment speed, attributes of the collateral, yield or price of bonds of comparable quality, coupon, maturity, and type as well as broker/dealer-supplied prices. Swap prices are derived using daily swap curves and models that incorporate a number of market data factors, such as discounted cash flows, trades, and values of the underlying reference instruments. Foreign currency exchange contracts and foreign cross currency exchange contracts are valued at the mean between the bid and 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 ask prices, which approximates fair value. Generally, other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith under the direction of the Trust’s Board of Trustees (Board). In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures or suspension of trading in a security. Each Fund may use fair value pricing more frequently for securities traded primarily in non-US markets because, among other things, most foreign markets close well before each Fund values its securities, generally as of 4:00pm Eastern time. The earlier close of these foreign markets gives rise to the possibility that significant events, including broad market moves, government actions or pronouncements, aftermarket trading, or news events may have occurred in the interim. Whenever such a significant

event occurs, each Fund may value foreign securities using fair value prices based on third-party vendor modeling tools (international fair value pricing). The foregoing valuation policies apply to restricted and unrestricted securities.

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 (RIC) under Subchapter M of the Internal Revenue Code of 1986, as amended, and make the requisite distributions to shareholders. The Funds evaluate 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 to be taken on each Fund’s federal income tax returns through the six months ended Sept. 30, 2017 and for all open federal income tax years (March 31, 2014–March 31, 2017) and has concluded that no provision for federal income tax is required in any 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, the Funds recognize interest accrued in unrecognized tax benefits in interest expense and penalties in other expenses on the “Statements of operations.” During the six months ended Sept. 30, 2017, 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 the Funds 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 Sept. 29, 2017, and matured on the next business day.

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 Sept. 30, 2017, the Fund had average reverse repurchase agreements of $2,966,224 for which it paid interest at an average rate of 0.59%. At Sept. 30, 2017, there were no open reverse repurchase agreements in the Fund.

To Be Announced Trades (TBA) — Optimum Fixed Income Fund may contract to purchase or sell securities for a fixed price at a transaction date beyond the customary settlement period (examples: when issued, delayed delivery, forward commitment, or TBA transactions) consistent with the Fund’s ability to manage its investment portfolio and meet redemption requests. These transactions involve a commitment by the Fund to purchase or sell securities for a predetermined price or yield with payment and delivery taking place more than three days in the future, or after a period longer than the customary settlement period for that type of security. No interest will be earned by the Fund on such purchases until the securities are delivered or the transaction is completed; however, the market value may change prior to delivery. At Sept. 30, 2017, the Fund posted $348,109 in securities collateral for TBA trades, which comprised of US treasury obligations, which is presented on the “Schedules of investments.” The Fund also received $922,000 cash collateral for TBA trades as of Sept. 30, 2017, which is shown as “Cash collateral due to brokers” on the “Statements of assets and liabilities.”

Foreign Currency Transactions — Transactions denominated in foreign currencies are recorded at the prevailing exchange rates on the valuation date in accordance with the Funds’ prospectus. The value of all assets and liabilities denominated in foreign currencies is translated daily into US dollars at the exchange rate of such currencies against the US dollar. Transaction gains or losses resulting from changes in exchange rates during the reporting period or upon settlement of the foreign currency transaction are reported in operations for the current period. The Funds generally bifurcate that portion of realized gains and losses on investments in debt securities which is due to changes in

108

foreign exchange rates from that which is due to changes in market prices of debt securities. That portion of gains (losses), which is due 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 and unrealized gain (loss) on investments.” The Funds report certain foreign currency related transactions as components of realized gains (losses) for financial reporting purposes, whereas such components are treated as ordinary income (loss) for federal income tax purposes.

Use of Estimates — Each Fund is an investment company, whose financial statements are prepared in conformity with US GAAP. Therefore, each Fund follows the accounting and reporting guidelines for investment companies. 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 the accrual basis. Discounts and premiums on debt securities are accreted or amortized to interest income, respectively, over the lives of the respective securities using the effective interest method. Realized gains (losses) on paydowns of asset- and mortgage-backed securities are classified as interest income. 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. Distributions received from investments in master limited partnerships are recorded as return of capital on investments on the ex-dividend date. 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. The Funds may distribute more frequently, if necessary for tax purposes. Dividends and distributions, if any, are recorded on the ex-dividend date.

Each Fund may receive earnings credits from its custodian when positive cash balances are maintained, which may be used to offset custody fees. There were no such earnings credits for the six months ended Sept. 30, 2017.

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 expense paid under this arrangement is included on the “Statements of operations” under “Dividend disbursing and transfer agent fees and expenses” with the corresponding expense offset shown under “Less expense paid indirectly.” For the six months ended Sept. 30, 2017, each Fund earned the following amounts under this agreement:

Optimum Fixed Income Fund	Optimum International Fund	Optimum Large Cap Growth Fund	Optimum Large Cap Value Fund	Optimum Small-Mid Cap Growth Fund	Optimum Small-Mid Cap Value Fund
$423	$402	$459	$459	$449	$452

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

Delaware Management Company (DMC), a series of Macquarie Investment Management Business Trust (formerly, Delaware 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.

Cross trades for the six months ended Sept. 30, 2017, were executed by the Funds pursuant to procedures adopted by the Board designed to ensure compliance with Rule 17a-7 under the 1940 Act. Cross trading is the buying or selling of portfolio securities between funds of investment companies, or between a fund of an investment company and another entity, that are or could be considered affiliates by virtue of having a common investment advisor (or affiliated investment advisors), common directors/trustees and/or common officers. At its regularly scheduled meetings, the Board reviews such transactions for compliance with the procedures adopted by the Board. Optimum Fixed Income Fund, Optimum Large Cap Growth Fund, Optimum Large Cap Value Fund, and Optimum Small Cap Value Fund did not engage in

Qualified late year ordinary losses represent losses realized from Jan. 1, 2017 through March 31, 2017 that in accordance with federal income tax regulations, the Funds have elected to defer and treat as having arisen in the following fiscal year. At March 31, 2017, qualified late year ordinary losses deferred for Optimum Small-Mid Cap Growth Fund were $1,114,999.

Under the Regulated Investment Company Modernization Act of 2010 (Act), net capital losses recognized for tax years beginning after Dec. 22, 2010 may be carried forward indefinitely, and their character is retained as short-term and/or long-term losses. Previously, net capital losses were carried forward for eight years and treated as short-term losses. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses.

At March 31, 2017, there were no capital loss carryforwards for Optimum Large Cap Growth Fund, Optimum Large Cap Value Fund, Optimum Small-Mid Cap Growth Fund, and Optimum Small-Mid Cap Value Fund. Capital loss carryforwards available to offset future realized capital gains, through the indicated expiration dates for Optimum Fixed Income Fund and Optimum International Fund were as follows:

	Pre-enactment capital loss Expiration date		No expiration Post-enactment capital loss character

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 below.

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

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

Securities valued at zero on the “Schedules of investments” are considered to be Level 3 investments in these tables.

As a result of utilizing international fair value pricing at Sept. 30, 2017, the majority of Optimum International Fund’s common stock investments and a portion of Optimum Large Cap Growth Fund’s and Optimum Large Cap Value Fund’s common stock investments were categorized as Level 2.

During the six months ended Sept. 30, 2017, there were no transfers between Level 1 investments, Level 2 investments, or Level 3 investments that had a significant impact to the Funds. This does not include transfers between Level 1 investments and Level 2 investments due to the Funds utilizing international fair value pricing during the period. In accordance with the fair valuation procedures described in Note 1, international fair value pricing of securities in each Fund occurs when market volatility exceeds an established rolling threshold. If the threshold is exceeded on a given date, then prices of international securities (those that traded on exchanges that close at a different time than the time that the Funds’ NAV is determined) are established using a separate pricing feed from a third-party vendor designed to establish a price for each such security as of the time that the Funds’ NAV is determined. Further, international fair value pricing uses other observable market-based inputs in place of the closing exchange price due to the events occurring after the close of the exchange or market on which the investment is principally traded, causing a change in classification between levels. Each Fund’s policy is to recognize transfers between levels based on fair value at the beginning of the reporting period.

A reconciliation of Level 3 investments is presented when each Fund has a significant amount of Level 3 investments at the beginning, interim, or end of the period in relation to each Fund’s net assets. With the exception of Optimum Small-Mid Cap Growth Fund, management has determined not to provide a reconciliation of Level 3 investments as they are not considered significant to each Fund’s net assets at the beginning, interim, or end of the period. With the exception of Optimum Small-Mid Cap Growth Fund, management has determined not to provide additional disclosure on Level 3 inputs since the Level 3 investments are not considered significant to each Fund’s net assets at the end of the period. There were no Level 3 investments during the six months ended Sept. 30, 2017 for Optimum Large Cap Value Fund and Optimum Small-Mid Cap Value Fund.

The following is a reconciliation of investments in which significant unobservable inputs (Level 3) were used in determining fair value for Optimum Small-Mid Cap Growth Fund:

	Convertible Preferred Stock
Beginning balance March 31, 2017	$	4,584,960
Sales		(1,065,862	)
Net realized gain		501,101
Transfers into Level 3		693,782
Transfers out of Level 3		(1,134,120	)
Net change in unrealized depreciation		(80,235	)
Ending balance Sept. 30, 2017	$	3,499,626
Net change in unrealized depreciation from investments still held at the end of the period	$	(184,152	)

When market quotations are not readily available for one or more portfolio securities, the Funds’ NAV shall be calculated by using the “fair value” of the securities as determined by the Pricing Committee. Such “fair value” is the amount that a Fund might reasonably expect to receive for the security (or asset) upon its current sale. Each such determination should be based on a consideration of all relevant factors, which are likely to vary from one pricing context to another. Examples of such factors may include, but are not limited to: (i) the type of security, (ii) the size of the holding, (iii) the initial cost of the security, (iv) the existence of any contractual restrictions of the security’s disposition, (v) the price and extent of public trading in similar securities of the issuer or of comparable companies, (vi) quotations or evaluated prices from broker/dealers and/or pricing services, (vii) information obtained from the issuer, analysts, and/or appropriate stock exchange (for exchange-traded securities), (viii) an analysis of the company’s financial statements, and (ix) an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold.

The Pricing Committee, or its delegate, employs various methods for calibrating these valuation approaches, including due diligence of the Funds’ pricing vendors and periodic back-testing of the prices that are fair valued under these procedures and reviews of any market related activity. The pricing of all securities fair valued by the Pricing Committee is subsequently reported to and approved by the Board on a quarterly basis.

Quantitative information about Level 3 fair value measurements for Optimum Small-Mid Cap Growth Fund are as follows:

Assets	Value		Valuation Techniques	Unobservable Inputs	Range of Unobservable Inputs		Weighted Average Discounted Enterprise Value / Revenue Multiple
Convertible			Comparable company approach. Estimated value of retained portion of purchase price held in escrow for contingencies.	Enterprise value / revenue multiple Range of comparable companies.
Preferred Stock		$3,359,551				1.8x to 11.2x		6.4x
Convertible Preferred Stock		140,075		Value of retained portion to be delivered to shareholders 18 months after transaction closes, less 10% liquidity discount.		N/A		N/A
Total		$3,499,626

A significant change to the inputs may result in a significant change to the valuation.

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.

Foreign Currency Exchange Contracts — Each Fund may enter into foreign currency exchange contracts and foreign cross currency exchange contracts as a way of managing foreign exchange rate risk. Each Fund may also 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 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 foreign currency exchange contracts and foreign cross currency exchange contracts does not eliminate fluctuations in the underlying prices of the securities, but does establish a rate of exchange that can be achieved in the future. Although foreign currency exchange contracts and foreign cross currency exchange contracts limit the risk of loss due to an unfavorable change in the value of the hedged currency, they also limit any potential gain that might result should the value of the currency change favorably. In addition, 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. During the six months ended Sept. 30, 2017, Optimum Small-Mid Cap Growth Fund and Optimum Small-Mid Cap Value Fund did not use foreign currency exchange contracts.

During the six months ended Sept. 30, 2017, Optimum Fixed Income Fund and Optimum Large Cap Growth Fund each used foreign currency exchange contracts to hedge the US dollar value of securities it already owns that are denominated in foreign currencies.

During the six months ended Sept. 30, 2017, Optimum International Fund and Optimum Large Cap Value Fund each used foreign currency exchange contracts to facilitate or expedite the settlement of portfolio transactions. Optimum International Fund also used foreign currency exchange contracts to fix the US dollar value of a security between trade date and settlement date.

During the six months ended Sept. 30, 2017, Optimum International Fund, Optimum Large Cap Growth Fund, and Optimum Large Cap Value Fund held foreign currency exchange contracts which are reflected on the “Statements of operations” under “Net realized and unrealized gain (loss) on foreign currency exchange contracts.”

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 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 fair value caused by changes in interest rates or market conditions. Upon entering into a futures contract, the

Optimum Fund Trust

5. Derivatives (continued)

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 $1,221,000 cash and securities collateral valued at $3,188,023, as margin for open futures contracts. Securities collateral are presented on the “Schedules of investments” and cash collateral is presented on the “Statements of assets and liabilities” as “Cash collateral due from brokers.”

During the six months ended Sept. 30, 2017, 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 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. 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.

During the six months ended Sept. 30, 2017, 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 adjust the Fund’s overall exposure to certain markets, to receive premiums for writing options, and to manage the Fund’s exposure to changes in foreign currencies.

Swap Contracts — Optimum Fixed Income Fund may enter into currency swap contracts, index swap contracts, inflation swaps, interest rate swap contracts, and CDS contracts in the normal course of pursuing its investment objective. The Fund may invest in interest rate swaps 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. The Fund will not be permitted to enter into any swap transactions unless, at the time of entering into such transactions, the unsecured long-term debt of the actual counterparty, combined with any credit enhancements, is rated at least BBB- by Standard & Poor’s Financial Services LLC. (S&P) or Baa3 by Moody’s Investors Service Inc. (Moody’s) or is determined to be of equivalent credit quality by DMC.

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

122

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 Sept. 30, 2017, 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 Sept. 30, 2017, 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 Sept. 30, 2017, the notional value of the protection sold was EUR 2,500,00 and USD 40,755,000, 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 Sept. 30, 2017, net unrealized appreciation of the protection sold was $1,233,042.

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 and (2) for cleared swaps, trading these instruments through a central counterparty.

During the six months ended Sept. 30, 2017, Optimum Fixed Income Fund used CDS contracts to hedge against credit events, to enhance total return, and to gain exposure to certain securities or markets.

Swaps Generally. 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 Sept. 30, 2017, for bilateral derivative contracts, Optimum Fixed Income Fund posted $1,710,000 in cash collateral for certain open derivatives, which is presented as “Cash collateral due from brokers” on the “Statements of assets and liabilities.” Optimum Fixed Income Fund posted $1,629,330 cash collateral for certain centrally cleared derivatives. The Fund also posted $3,560,535 in securities collateral comprised of US treasury obligations for certain open centrally cleared derivative contracts. Cash collateral is presented as “Cash collateral due from brokers” on the “Statements of assets and liabilities” and securities collateral is presented on the “Schedules of investments.” At Sept. 30, 2017, for

6. Offsetting

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

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

At Sept. 30, 2017, the Funds had the following assets and liabilities subject to offsetting provisions:

Securities Lending

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

As of Sept. 30, 2017, the following table is a summary of Optimum International Fund’s securities lending agreements by counterparty which are subject to offset under an MSLA:

Counterparty	Securities Loaned at Value	Cash Collateral Received(a)	Fair value of Non-Cash Collateral Received	Net Exposure(b)
The Bank of New York Mellon	$20,814,375	$(14,034,900)	$(6,779,475)	$—

^(a) The value of the related collateral exceeded the value of the repurchase agreements and securities lending transactions as of Sept. 30, 2017.

^(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 may lend its securities pursuant to a security lending agreement (Lending Agreement) with The Bank of New York Mellon (BNY Mellon). At the time a security is loaned, the borrower must post collateral equal to the required percentage of the market value of the loaned security, including any accrued interest. The required percentage is: (1) 102% with respect to US securities and foreign securities that are denominated and payable in US dollars; and (2) 105% with respect to foreign securities. With respect to each loan, if on any business day the aggregate market value of securities collateral plus cash collateral held is less than the aggregate market value of the securities that 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

(continues )  129

Optimum Fund Trust

7. Securities Lending (continued)

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.

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

In the event of default or bankruptcy by the lending agent, realization and/or retention of the collateral may be subject to legal proceedings. In the event the borrower fails to return loaned securities and the collateral received is insufficient to cover the value of the loaned securities and provided such collateral shortfall is not the result of investment losses, the lending agent has agreed to pay the amount of the shortfall to the Funds or, at the discretion of the lending agent, replace the loaned securities. The Funds continue to record dividends or interest, as applicable, on the securities loaned and are subject to changes in value of the securities loaned that may occur during the term of the loan. The Funds have the right under the Lending Agreement to recover the securities from the borrower on demand. With respect to security loans collateralized by non-cash collateral, the Funds receive loan premiums paid by the borrower. With respect to security loans collateralized by cash collateral, the earnings from the collateral investments are shared among the Funds, the security lending agent, and the borrower. The Funds record 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 the collateral investment account defaulted or became impaired. Under those circumstances, the value of a Fund’s cash collateral account may be less than the amount a Fund would be required to return to the borrowers of the securities and that Fund would be required to make up for this shortfall.

During the six months ended Sept. 30, 2017, Optimum Fixed Income Fund, Optimum Large Cap Growth Fund, Optimum Large Cap Value Fund, Optimum Small-Mid Cap Growth Fund, and Optimum Small-Mid Cap Value Fund had no securities on loan.

The following table reflects a breakdown of transactions accounted for as secured borrowings, the gross obligation by the type of collateral pledged, and the remaining contractual maturity of those transactions as of Sept. 30, 2017 for Optimum International Fund:

Securities Lending Transactions	Overnight and Continuous		Under 30 days	Between 30 & 90 days	Over 90 days	Total
Common stock	$	14,522,218	$—	$—	$—	$	14,522,218

8. Credit and Market Risk

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 United States. 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.

Optimum Fixed Income Fund invests in high yield fixed income securities, which are securities rated lower than BBB by S&P and lower than Baa3 by Moody’s, or similarly rated by another nationally recognized statistical rating organization. Investments in these higher yielding securities are generally accompanied by a greater degree of credit risk than higher rated securities. Additionally, lower rated

130

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 the Fund may be required to rely upon another lending institution to collect and pass on to the Fund amounts payable with respect to the loan and to enforce the Fund’s rights under the loan and other direct indebtedness, an insolvency, bankruptcy, or reorganization of the lending institution may delay or prevent the Fund from receiving such amounts. The highly leveraged nature of many loans may make them especially vulnerable to adverse changes in economic or market conditions. Investments in such loans and other direct indebtedness may involve additional risk to the Fund.

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

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. 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 as a result of defaults 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 Sept. 30, 2017. 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 invests 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.

Notes to financial statements

Optimum Fund Trust

8. Credit and Market Risk (continued)

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 (the Act), as amended, 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 Act, which exempts from registration transactions by an issuer not involving any public offering. The relative illiquidity of these securities may impair the Funds 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, 4(a)(2) 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 the Funds’ existing contracts and expects the risk of loss to be remote.

10. General Motors Term Loan Litigation

Optimum Fixed Income Fund received notice of a litigation proceeding related to a General Motors Corporation (G.M.) term loan participation previously held by the Fund in 2009. We believe the matter subject to the litigation notice will likely lead to a recovery from the Fund of certain amounts received by the Fund because a US Court of Appeals has ruled that the Fund and similarly situated investors were unsecured creditors rather than secured lenders of G.M. as a result of an erroneous Uniform Commercial Code filing made by a third party. The Fund received the full principal on the loans in 2009 after the G.M. bankruptcy. However, based upon the court ruling the estate is seeking to recover such amounts arguing that, as unsecured creditors, the Fund should not have received payment in full. Based upon currently available information related to the litigation and the Fund’s potential exposure, the Fund recorded a contingent liability of $1,385,788 and an asset of $415,736 based on the expected recoveries to unsecured creditors as of Sept. 30, 2017 that resulted in a net decrease in the Fund’s NAV to reflect this likely recovery.

11. Recent Accounting Pronouncements

In October 2016, the Securities and Exchange Commission released its Final Rule on Investment Company Reporting Modernization (Rule). The Rule contains amendments to Regulation S-X which impact financial statement presentation, particularly the presentation of derivative investments. The financial statements presented are in compliance with the most recent Regulation S-X amendments.

12. Subsequent Events

Effective Oct. 12, 2017, ClearBridge Investments, LLC (ClearBridge) replaced Fred Alger Management, Inc. (Alger) as a sub-advisor for Optimum Large Cap Growth Fund.

Management has determined that no other material events or transactions occurred subsequent to Sept. 30, 2017 that would require recognition or disclosure in the Funds’ financial statements.

Board Consideration of Optimum Fund Trust Investment Management and Sub-Advisory Agreements at a Meeting Held September 19–20, 2017

At a meeting held Sept. 19-20, 2017 (the “September 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”); (ii) approved a new Sub-Advisory Agreement between DMC and ClearBridge Investments LLC (“ClearBridge”) to replace Fred Alger Management, Inc. (“Alger”) as a sub-adviser to Optimum Large Cap Growth Fund, effective on or about October 6, 2017; and (iii) approved the continuation of Sub-Advisory Agreements for the existing sub-advisers of all the Funds, limited in the case of Alger until its replacement by ClearBridge and excluding Acadian Asset Management LLC (“Acadian”), which was approved at a Board meeting held June 21, 2017 (the “June Meeting”), as described in more detail below.

In reaching such decisions, the Board took into account information furnished and discussed throughout the year at quarterly Board meetings, as well as information furnished specifically for the renewal reviews conducted at the September 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 portfolios managers from DMC and each 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 renewals 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 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 renewal process also included a report for each Fund prepared by Lipper Inc., an independent third-party analyst and subsidiary of Broadridge Inc. (“Lipper”), 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 reaching its decision with respect to the Sub-Advisory Agreement with ClearBridge, the Board considered and reviewed information about ClearBridge, including its personnel, operations and financial condition, which had been provided by ClearBridge. The Board also reviewed material furnished by DMC (with the assistance of LPL), including: a memorandum from DMC reviewing the Sub-Advisory Agreement with, and the various services proposed to be rendered by, ClearBridge; research and analysis supporting DMC’s recommendation to hire ClearBridge for Optimum Large Cap Growth Fund; a description of the proposed sub-advisory fees under the Sub-Advisory Agreement with ClearBridge, along with fees that ClearBridge charges to other comparable accounts; information concerning Clearbridge’s organizational structure and the experience of its investment management personnel; a “due diligence” report describing various material items in relation to ClearBridge’s personnel, organization and policies; copies of ClearBridge’s Form ADV, compliance policies and procedures and its Code of Ethics; and a copy of the Sub-Advisory Agreement with ClearBridge.

In considering such materials, the Independent Trustees received assistance and advice from and met separately with independent counsel. In this regard, the Independent Trustees reviewed with independent counsel their legal duties and obligations in connection with the approval and/or renewal 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 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 September Meeting. While the Investment Management Agreement and related Sub-Advisory Agreements for all Funds (including the Sub-Advisory Agreement for ClearBridge but not including the Sub-Advisory Agreement for Acadian) were considered at the September 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.

Board Consideration of Optimum Fund Trust Investment Management and Sub-Advisory Agreements at a Meeting Held September 19–20, 2017 (continued)

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 Optimum Fixed Income Fund) to each of the Funds.

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 Optimum Fixed Income Fund) with the investment policies and restrictions of the Funds advised, as well as their adherence to various compliance and other procedures based on presentations made by the sub-advisers’ portfolio managers (and DMC’s portfolio managers with respect to Optimum Fixed Income Fund) and reports of Management’s discussions with the sub-advisers, as well as certificates and materials furnished in connection with Board meetings and the contract renewals.

In considering the nature, extent and quality of the services to be provided by ClearBridge, the Board reviewed the services to be provided by ClearBridge pursuant to its Sub-Advisory Agreement, noting specifically that the Sub-Advisory Agreement with ClearBridge contains substantially similar provisions to those in the Sub-Advisory Agreement for Alger, except for the provisions relating to the fees. The Board reviewed materials provided by ClearBridge regarding the experience and qualifications of the personnel who will be responsible for managing the portion of Optimum Large Cap Growth Fund to be subadvised by ClearBridge. The Board also placed weight on the performance of a representative ClearBridge portfolio that utilized the investment process and parameters that would be employed by ClearBridge with respect to its portion of Optimum Large Cap Growth Fund (the “ClearBridge Account”). The Board also considered that ClearBridge would serve as a sub-adviser of the Fund along with T. Rowe Price Associates, Inc. (“T. Rowe Price”). In this regard, the Board considered the compatibility of the two sub-advisers’ investment philosophies and methodologies that they would each employ for the Fund.

Based upon these considerations, the Board was satisfied with the nature and quality of the overall services to be provided by the existing sub-advisers and ClearBridge to each Fund, as applicable, and its shareholders and was confident in the abilities of the existing sub-advisers and ClearBridge 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 September Meeting), particular attention in assessing performance was given to the Lipper Reports furnished in connection with the contract renewals. 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, 2017, 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 calendar years and periods ended June 30, 2017. The Trustees also compared Fund performance to other industry benchmarks, including measures of risk-adjusted performance of a Fund, as part of their evaluation of investment performance. In regards to the appointment of ClearBridge for Optimum Large Cap Growth Fund, the Board also reviewed the performance of the ClearBridge Account. 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 to be in the middle performing quintile of its Lipper Performance Universe for the one year period, and on an annualized basis in the second lowest performing quintile of its Performance Universe for the three year period, the lowest performing quintile of its Performance Universe for the five year period, and in the middle performing quintile of its Performance Universe for the previous ten year period. It was also noted that the Fund had outperformed its benchmark on a gross performance basis for the one year, three year, five year, and ten year periods ended June 30, 2017. The Board discussed with Management the reasons for the Fund’s relative underperformance versus the Fund’s Lipper Performance Universe for the three and five year periods but, given that the Fund’s comparative performance results had improved for the one year period and given that the Fund had consistently outperformed its benchmark, the Trustees found the overall performance results of the Fund to be acceptable.

134

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 to be in the highest performing quintile of its Performance Universe for the one year period, and on an annualized basis to be in the second highest performing quintile of its Performance Universe for the three year period, and the middle quintile of its Performance Universe for the five year period, and the second lowest quintile of its Performance Universe for the ten year period. The Trustees discussed with Management the reasons for the relative underperformance for the ten year period. It was noted that Earnest Partners, LLC and Acadian had been appointed as the Fund’s sub-advisers in October 2013 and January 2015, respectively, and that the Fund’s comparative performance results had improved over more recent periods, including the one year period. The Trustees found the overall comparative performance results of the Fund to be acceptable.

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 to be in the highest performing quintile of its Lipper Performance Universe for the one year period, and on an annualized basis to be in the highest performing quintile of the Performance Universe for the three and five year periods, and the middle performing quintile for the ten year period. The Trustees found such overall comparative results to be satisfactory, but also noted Management’s recommendation to appoint ClearBridge as a sub-adviser to the Fund to replace Alger. In connection therewith, the Trustees reviewed a “combination analysis” showing various performance metrics that would have resulted from combining the performance of the ClearBridge Account with the performance of T. Rowe Price over various time periods. The Trustees also noted Management’s belief that, based on the combination analysis, ClearBridge’s approach to investing should add attractive diversification qualities and stronger style consistency in the large cap growth category for the Fund.

Optimum Large Cap Value Fund — The Lipper Performance Universe for this Fund consisted of the Fund and all retail and institutional large-cap core funds as selected by Lipper. The Lipper Report showed the Fund’s investment performance to be in the second lowest performing quintile of its Lipper Performance Universe for the one year period, and on an annualized basis to be in the lowest performing quintile of its Lipper Universe for each of the three, five, and ten year periods. The Trustees discussed with Management the reasons for the relative underperformance for the Fund and the steps taken to improve such performance. In particular, it was noted that Rothschild Asset Management Inc. (“Rothschild”) had been appointed as a sub-adviser to the Fund to replace Herndon Capital Management LLC in October 2016. The Board noted that one indication of improved performance was that the Fund had outperformed its benchmark on a gross performance basis for the one year period ended June 30, 2017. Although the Board was not satisfied with the comparative performance results of the Fund, the Board believed that Management was taking appropriate actions to improve performance, noting the appointment of Rothschild as a sub-adviser to the Fund, but intend to closely monitor future performance.

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 to be in the middle performing quintile of its Lipper Performance Universe for the one year period, and on an annualized basis to be in the lowest performing quintile of such Universe for the previous three and ten year periods, and the second lowest performing quintile of its Lipper Performance Universe for the five year period. The Trustees discussed with Management the reasons for the Fund’s relative underperformance and the steps taken to improve such performance. In particular, the Trustees and Management discussed the appointment in early 2016 of Columbus Circle Investors (“CCI”) and Peregrine Capital Management, Inc. (“Peregrine”) as sub-advisers to the Fund to replace the Fund’s two prior sub-advisers. The Trustees noted that both CCI and Peregrine had performed well since their appointments to the Fund and that the Fund’s comparative performance results had improved over various periods. The Board noted that the Fund had outperformed its benchmark on a gross performance basis for the one year period ended June 30, 2017. Although the Trustees were not satisfied with the historical comparative performance of the Fund and intend to closely monitor future performance, the Board believed that Management has taken appropriate actions to improve performance, noting the appointments of CCI and Peregrine as sub-advisers to the Fund.

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 to be in the second lowest performing quintile of its Lipper Performance Universe for the one year period, and on an annualized basis to be in the lowest performing quintile of such Universe for the three, five, and ten year periods. The Trustees discussed with Management the reasons for the Fund’s relative underperformance and the steps recently taken to improve such performance. In particular, the Trustees and Management noted the appointment in early 2016 of LSV Asset Management (“LSV”) as a sub-adviser to the Fund to replace two of the Fund’s prior sub-advisers. The Trustees noted that LSV had performed well since its appointment to the Fund and that the Fund’s comparative performance results for the one year period had modestly improved. The Board noted that the Fund had outperformed its benchmark on a gross performance basis for the one year period ended June 30, 2017. Although the Board was not satisfied with the historical comparative performance for the Fund, the Board believed that

Board Consideration of Optimum Fund Trust Investment Management and Sub-Advisory Agreements at a Meeting Held September 19–20, 2017 (continued)

Management has taken appropriate actions to improve performance, noting the appointment of LSV as a sub-adviser to the Fund, but intends to closely monitor future performance.

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 sub-adviser were the product of arms-length negotiations between DMC and each sub-adviser, and the Board 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 sub-adviser, 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 Group. 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 showed the actual total expenses and investment management fees (taking into account expense waivers) of each Fund to be the highest or towards the highest in its respective Lipper Expense Group. The Lipper Report also provided information on the actual total expenses (taking into account expense waivers) for each Fund versus a broader Lipper Expense Universe. This portion of the Lipper Report showed that the Funds’ actual total expense percentile rankings versus the Lipper Expense Universe improved as compared to the Funds’ rankings versus the Lipper Expense Group. The Board also noted the favorable impact of the Fee Restructuring (as defined below) on the Funds’ actual total expense ratios, including as compared to the Lipper Expense Universe.

In regards to considering the appropriateness of the sub-advisory fees to be charged by ClearBridge to the Large Cap Growth Fund, the Board was provided with a description of the fees to be charged by ClearBridge under its Sub-Advisory Agreement for the Fund, which showed them to be slightly lower than the sub-advisory fees charged by Alger under its respective Sub-Advisory Agreement at the Fund’s current amount of assets under management. The Board discussed the impact that the differences in such sub-advisory fees would have on DMC’s profitability for the Fund. The Board also was provided with information showing that ClearBridge’s sub-advisory fees for the Fund were competitive with those charged by ClearBridge to other comparable investment companies or accounts it advises, and was informed by Management that ClearBridge’s fees for the Fund were competitive with fees of other sub-advisers being considered as possible sub-advisers to the Fund. The Board also noted that the management fee paid by the Fund to DMC would stay the same at current asset levels.

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 30, 2018. The Trustees also noted that Management had in recent years agreed to various restructurings and overall reductions in fees charged to the Funds through several mechanisms, including a recent fee restructuring with regard to the investment management, administration and transfer agency fee schedules for each of the Funds to reduce the Funds’ 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 restructurings.

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, 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 sub-advisers were the

136

product of arms-length negotiations between DMC and each sub-adviser. Information about ClearBridge’s profitability from its relationship with the Large Cap Growth Fund was not available because it had not begun to provide services to the Fund. 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 the Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act and recent US Securities and Exchange Commission 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 (including ClearBridge) 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 get larger at some point, 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.

Board Consideration of Optimum International Fund Sub-Advisory Agreement at Meeting Held June 21, 2017

At the June Meeting, the Board, including a majority of the Independent Trustees, approved a new Sub-Advisory Agreement between DMC and Acadian, under which Acadian would continue to serve as a sub-adviser to Optimum International Fund after the Transaction (as defined below). The decision to approve a new Sub-Advisory Agreement for Acadian arose from a possible “change of control” of Acadian, under applicable provisions of the Investment Company Act of 1940, following a series of transactions made by Acadian’s ultimate parent company that significantly reduced its indirect ownership interest in Acadian (collectively, the “Transaction”).

Because Acadian was an existing sub-adviser to Optimum International Fund, the Board took into account information furnished and discussed throughout the year at quarterly Board meetings with respect to Acadian, as well as information furnished specifically for the contract approval proposed at the June Meeting. Information furnished at Board meetings throughout the year included: an analysis by Management (with the assistance of its consultant, LPL) of the investment performance of Acadian and the portion of the Optimum International Fund’s assets (i.e., “sleeve” of Optimum International Fund) it sub-advised; information comparing, among other things, the Optimum International Fund’s investment performance with those of other mutual funds deemed comparable by Lipper; and compliance reports and related certifications furnished by Acadian and Management. Material furnished specifically in connection with the June Meeting and the review of the Sub-Advisory Agreement for Acadian included: a memorandum from Management reviewing the Sub-Advisory Agreement and the various services proposed to be rendered by Acadian; a description of Acadian’s proposed sub-advisory fees under the Sub-Advisory Agreement showing their competitiveness with the fees charged by Acadian to other comparable accounts; information concerning Acadian’s organizational structure and the experience of its investment management personnel; a “due diligence” report describing various material items in relation to Acadian’s personnel, organization and policies; copies of Acadian’s compliance policies and procedures and its Code of Ethics; a copy of the Sub-Advisory Agreement; and materials specifically discussing the Transaction.

In considering such materials, the Independent Trustees received assistance and advice from and met separately with their independent counsel. In this regard, the Independent Trustees reviewed with independent counsel their legal duties and obligations in connection with the approval of the Sub-Advisory Agreement for Acadian and discussed, in detail, the matters related to such approval. The materials prepared by Management specifically in connection with the approval of the Sub-Advisory Agreement were provided to the Independent Trustees in advance of the June Meeting. While attention was given to all information furnished, the following discusses some primary factors relevant to the Board’s decision. 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. In considering the nature, extent and quality of the services to be provided by Acadian, the Board specifically considered that the Sub-Advisory Agreement for Acadian contains substantially similar provisions to those in the prior Acadian sub-advisory agreement for Optimum International Fund. The Board reviewed materials provided by Acadian regarding its experience and the qualifications of its personnel, and placed weight on Acadian’s representation that there were no planned changes with respect to Acadian’s personnel responsible for security selection and portfolio management of the portion of the Optimum International Fund’s assets managed by Acadian in connection with the Transaction. The quality of the services of Acadian was also considered primarily in respect to the investment performance of its sleeve of Optimum International Fund as described further in the “Investment Performance” section on the next page. The Board was also satisfied with the adherence by Acadian with the investment policies and restrictions of Optimum International Fund, as well as

Board Consideration of Optimum International Fund Sub-Advisory Agreement at Meeting Held June 21, 2017 (continued)

their adherence to various Fund compliance and other procedures. Based upon these considerations, the Board determined that the nature, extent and quality of the services to be provided by Acadian under the Sub-Advisory Agreement were satisfactory.

Investment performance. The Board placed significant emphasis on Acadian’s prior investment performance on its sleeve of Optimum International Fund. While consideration was given to performance reports and discussions throughout the year, particular attention in assessing performance was given to Acadian’s performance on its portion of Optimum International Fund to date relative to the Fund’s peers and benchmark. The Board was satisfied with such performance. As noted above, the Board placed weight on Acadian’s representation that there are no planned changes with respect to the Acadian personnel currently responsible for security selection and portfolio management of its portion of Optimum International Fund in connection with the Transaction. The Board believed such information and analysis evidenced the benefits to Optimum International Fund of retaining Acadian as a sub-adviser and the high quality of portfolio management services expected to be provided by Acadian under the Sub-Advisory Agreement.

Advisory fees; profitability; and economies of scale. The Board was provided with a description of the fees to be charged by Acadian under the Sub-Advisory Agreement which showed them to be identical to the sub-advisory fees from the prior Acadian sub-advisory agreement for Optimum International Fund. The Board also was provided with information showing that Acadian’s fees were competitive with those charged by Acadian to other comparable investment companies or accounts. The Board was informed that Acadian may receive certain fall-out benefits in connection with their relationship with Optimum International Fund, such as soft-dollar arrangements. The Board also noted that the management fee paid by Optimum International Fund to DMC would stay the same at current asset levels, and that Management’s profitability is not expected to be impacted following the re-approval of Acadian at current asset levels. The Board was also provided with profitability information with respect to the portion of Optimum International Fund sub-advised by Acadian. The Trustees recognized that, to the extent the Optimum International Fund’s assets increase, economies of scale may result in DMC realizing a larger profit margin on management services provided to the Fund. The Trustees also noted that economies of scale are shared with Optimum International Fund and its shareholders through investment management fee breakpoints so that as the Fund grows in size, its effective investment management fee rate declines. Based upon such facts, the Board believed that the fees to be charged by Acadian under the Sub-Advisory Agreement was fair and reasonable in relation to the services being provided.
