Disclosure of Series expenses

For the six-month period from January 1, 2023 to June 30, 2023 (Unaudited)

The investment objective of the Series is to seek long-term capital appreciation.

As a shareholder of the Series, you incur ongoing costs, which may include management fees; distribution and service (12b-1) fees; and other Series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Series and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire six-month period from January 1, 2023 to June 30, 2023.

Actual expenses

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

Hypothetical example for comparison purposes

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

Please note that the expenses shown in the table are meant to highlight your ongoing costs only. As a shareholder of the Series, you do not incur any transaction costs, such as sales charges (loads), redemption fees or exchange fees, but shareholders of other funds may incur such costs. Also, the fees related to the variable annuity investment or the deferred sales charge that could apply have not been included. Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. The Series’ expenses shown in the table reflect fee waivers in effect and assume reinvestment of all dividends and distributions.

Expense analysis of an investment of $1,000

In addition to the Series’ expenses reflected above, the Series also indirectly bears its portion of the fees and expenses of any investment companies (Underlying Funds) in which it invests. The table above does not reflect the expenses of any Underlying Funds.

Sector designations may be different from the sector designations presented in other Series materials. The sector designations may represent the investment manager’s internal sector classifications, which may result in the sector designations for one fund being different from another fund’s sector designations.

*To monitor compliance with the Series’ concentration guidelines as described in the Series’ Prospectus and Statement of Additional Information, the Information Technology sector (as disclosed herein for financial reporting purposes) is subdivided into a variety of “industries” (in accordance with the requirements of the Investment Company Act of 1940, as amended). The Information Technology sector consisted of Computers, Electronics, Electronic Components-Semiconductor, Internet, Semiconductor Components-Integrated Circuits, and Software. As of June 30, 2023, such amounts, as a percentage of total net assets were 1.83%, 2.05%, 19.77%, 0.81%, 12.42%, and 0.77%, respectively. The percentage in any such single industry will comply with the Series’ concentration policy even if the percentage in the Information Technology sector for financial reporting purposes may exceed 25%.

Notes to financial statements

Delaware VIP Trust (Trust) is organized as a Delaware statutory trust. The Trust consists of 10 series, each of which is treated as a separate entity for certain matters under the Investment Company Act of 1940, as amended (1940 Act). These financial statements and the related notes pertain to Delaware VIP Emerging Markets Series (Series). The Trust is an open-end investment company. The Series is considered diversified under the 1940 Act and offers Standard Class and Service Class shares. The Standard Class shares do not carry a distribution and service (12b-1) fee and the Service Class shares carry a 12b-1 fee. The shares of the Series are sold only to separate accounts of life insurance companies.

1. Significant Accounting Policies

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

Security Valuation — Equity securities and exchange-traded funds (ETFs), except those traded on the Nasdaq Stock Market LLC (Nasdaq), are valued at the last quoted sales price as of the time of the regular close of the New York Stock Exchange on the valuation date. Equity securities and ETFs traded on the Nasdaq are valued in accordance with the Nasdaq Official Closing Price, which may not be the last sales price. If, on a particular day, an equity security or ETF does not trade, the mean between the bid and the ask prices will be used, which approximates fair value. Equity securities listed on a foreign exchange are normally valued at the last quoted sales price on the valuation date. Open-end investment companies, other than ETFs, are valued at their published net asset value (NAV). 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. Generally, other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by the Series’ valuation designee, Delaware Management Company (DMC). Subject to the oversight of the Trust’s Board of Trustees (Board), DMC, as valuation designee, has adopted policies and procedures to fair value securities for which market quotations are not readily available consistent with the requirements of Rule 2a-5 under the 1940 Act. In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures or suspension of trading in a security. Restricted securities and private placements are valued at fair value.

Federal and Foreign Income Taxes — No provision for federal income taxes has been made as the Series intends to continue to qualify for federal income tax purposes as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended, and make the requisite distributions to shareholders. The Series evaluates tax positions taken or expected to be taken in the course of preparing the Series’ tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold are recorded as a tax benefit or expense in the current year. Management has analyzed the Series’ tax positions taken or expected to be taken on the Series’ federal income tax returns through the six months ended June 30, 2023, and for all open tax years (years ended December 31, 2019–December 31, 2022), and has concluded that no provision for federal income tax is required in the Series’ financial statements. In regard to foreign taxes only, the Series has open tax years in certain foreign countries in which it invests that may date back to the inception of the Series. If applicable, the Series recognizes interest accrued on unrecognized tax benefits in interest expense and penalties in “Other” on the “Statement of operations.” During the six months ended June 30, 2023, the Series 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 classes of the Series on the basis of daily net assets of each class. Distribution expenses relating to a specific class are charged directly to that class.

Foreign Currency Transactions — Transactions denominated in foreign currencies are recorded at the prevailing exchange rates on the valuation date in accordance with the Series’ 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 Series generally does not bifurcate that portion of realized gains and losses on investments which is due to changes in foreign exchange rates from that which is due to changes in market prices. These gains and losses are included on the “Statement of operations” under “Net realized gain (loss) on investments.” The Series reports certain foreign currency related transactions as components of realized gains (losses) for financial reporting purposes, whereas such components are treated as ordinary income (loss) for federal income tax purposes.

Notes to financial statements

Delaware VIP^® Trust — Delaware VIP Emerging Markets Series

1. Significant Accounting Policies (continued)

Derivative Financial Instruments — The Series may invest in various derivative financial instruments. These instruments are used to obtain exposure to a security, commodity, index, market, and/or other assets without owning or taking physical custody of securities, commodities and/or other referenced assets or to manage market, equity, credit, interest rate, foreign currency exchange rate, commodity and/or other risks. Derivative financial instruments may give rise to a form of economic leverage and involve risks, including the imperfect correlation between the value of a derivative financial instrument and the underlying asset, possible default of the counterparty to the transaction or illiquidity of the instrument. Pursuant to Rule 18f-4 under the 1940 Act, among other things, the Series must either use derivative financial instruments with embedded leverage in a limited manner or comply with an outer limit on fund leverage risk based on value-at-risk. The Series’ successful use of a derivative financial instrument depends on the investment adviser’s ability to predict pertinent market movements accurately, which cannot be assured. The use of these instruments may result in losses greater than if they had not been used, may limit the amount of appreciation the Series can realize on an investment and/or may result in lower distributions paid to shareholders. The Series’ investments in these instruments, if any, are discussed in detail in the Notes to financial statements.

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

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

Other — Expenses directly attributable to the Series are charged directly to the Series. Other expenses common to various funds within the Delaware Funds by Macquarie^® (Delaware Funds) are generally allocated among such funds on the basis of average net assets. Management fees and certain other expenses are paid monthly. Security transactions are recorded on the date the securities are purchased or sold (trade date) for financial reporting purposes. Costs used in calculating realized gains and losses on the sale of investment securities are those of the specific securities sold. Dividend income is recorded on the ex-dividend date and interest income is recorded on an accrual basis. Taxable non-cash dividends are recorded as dividend income. Foreign dividends are also recorded on the ex-dividend date or as soon after the ex-dividend date that the Series is aware of such dividends, net of all tax withholdings, a portion of which may be reclaimable. Withholding taxes and reclaims on foreign dividends have been recorded in accordance with the Series’ understanding of the applicable country’s tax rules and rates. Income and capital gain distributions from any Underlying Funds in which the Series invests are recorded on the ex-dividend date. The Series may pay foreign capital gains taxes on certain foreign securities held, which are reported as components of realized losses for financial reporting purposes, whereas such components are treated as ordinary loss for federal income tax purposes. The Series will accrue such taxes as applicable based upon current interpretations of the tax rules and regulations that exist in the markets in which it invests. The Series declares and pays dividends from net investment income and distributions from net realized gain on investments, if any, at least annually. The Series may distribute more frequently, if necessary for tax purposes. Dividends and distributions, if any, are recorded on the ex-dividend date.

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

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

In accordance with the terms of its investment management agreement, the Series pays DMC, a series of Macquarie Investment Management Business Trust and the investment manager, an annual fee which is calculated daily and paid monthly at the rates of 1.25% on the first $500 million of average daily net assets of the Series, 1.20% on the next $500 million, 1.15% on the next $1.5 billion, and 1.10% on average daily net assets in excess of $2.5 billion.

DMC has contractually agreed to waive all or a portion of its investment advisory fees and/or pay/reimburse expenses (excluding any 12b-1 fees, acquired fund fees and expenses, taxes, interest, short sale dividend and interest expenses, brokerage fees, certain insurance costs, and nonroutine expenses or costs, including, but not limited to, those relating to reorganizations, litigation, conducting shareholder meetings, and liquidations), in order to prevent total annual series operating expenses from exceeding 1.18% of the Series’ average daily net assets for the Standard Class and the Service Class from January 1, 2023 through June 30, 2023.* These waivers and reimbursements may only be terminated by agreement of DMC and the Series. The waivers and reimbursements are accrued daily and received monthly.

DMC may permit its affiliate, Macquarie Investment Management Global Limited (MIMGL) to execute Series security trades on its behalf. DMC may also seek quantitative support from MIMGL. Although MIMGL serve as sub-advisor, DMC has ultimate responsibility for all investment advisory services. For these services, DMC, not the Series, may pay MIMGL a portion of its investment management fee.

Delaware Investments Fund Services Company (DIFSC), an affiliate of DMC, provides fund accounting and financial administrative oversight services to the Series. For these services, DIFSC’s fees are calculated daily and paid monthly, based on the aggregate daily net assets of all funds within the Delaware Funds at the following annual rates: 0.00475% of the first $35 billion; 0.0040% of the next $10 billion; 0.0025% of the next $45 billion; and 0.0015% of aggregate average daily net assets in excess of $90 billion (Total Fee). Each fund in the Delaware Funds pays a minimum of $4,000, which, in aggregate, is subtracted from the Total Fee. Each fund then pays its portion of the remainder of the Total Fee on a relative NAV basis. This amount is included on the “Statement of operations” under “Accounting and administration expenses.” For the six months ended June 30, 2023, the Series paid $10,295 for these services.

DIFSC is also the transfer agent and dividend disbursing agent of the Series. For these services, DIFSC’s fees are calculated daily and paid monthly, at the annual rate of 0.0075% of the Series’ average daily net assets. This amount is included on the “Statement of operations” under “Dividend disbursing and transfer agent fees and expenses.” For the six months ended June 30, 2023, the Series paid $21,310 for these services. Pursuant to a sub-transfer agency agreement between DIFSC and BNY Mellon Investment Servicing (US) Inc. (BNYMIS), BNYMIS provides certain sub-transfer agency services to the Series. Sub-transfer agency fees are paid by the Series and are also included on the “Statement of operations” under “Dividend disbursing and transfer agent fees and expenses.” The fees that are calculated daily and paid as invoices are received on a monthly or quarterly basis.

Pursuant to a distribution agreement and distribution plan, the Series pays Delaware Distributors, L.P. (DDLP), the distributor and an affiliate of DMC, an annual 12b-1 fee of 0.30% of the average daily net assets of the Service Class shares. The fees are calculated daily and paid monthly. Standard Class shares do not pay 12b-1 fees.

As provided in the investment management agreement, the Series bears a portion of the cost of certain resources shared with DMC, including the cost of internal personnel of DMC and/or its affiliates that provide legal and regulatory reporting services to the Series. For the six months ended June 30, 2023, the Series paid $5,881 for internal legal and regulatory reporting services provided by DMC and/or its affiliates’ employees. This amount is included on the “Statement of operations” under “Legal fees.”

Trustees’ fees include expenses accrued by the Series for each Trustee’s retainer and meeting fees. Certain officers of DMC, DIFSC, and DDLP are officers and/or Trustees of the Trust. These officers and Trustees are paid no compensation by the Series.

In addition to the management fees and other expenses of the Series, the Series indirectly bears the investment management fees and other expenses of any Underlying Funds including ETFs in which it invests. The amount of these fees and expenses incurred indirectly by the Series will vary based upon the expense and fee levels of any Underlying Funds and the number of shares that are owned of any Underlying Funds at different times.

*The aggregate contractual waiver period covering this report is from April 29, 2022 through April 30, 2024.

3. Investments

For the six months ended June 30, 2023, the Series made purchases and sales of investment securities other than short-term investments as follows:

At June 30, 2023, the cost and unrealized appreciation (depreciation) of investments for federal income tax purposes have been estimated since final tax characteristics cannot be determined until fiscal year end. At June 30, 2023, the cost and unrealized appreciation (depreciation) of investments for the Series were as follows:

At December 31, 2022, capital loss carryforwards available to offset future realized capital gains were as follows:

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

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

The following table summarizes the valuation of the Series’ investments by fair value hierarchy levels as of June 30, 2023:

¹The value represents valuations of Russian Common Stocks for which Management has determined include significant unobservable inputs as of June 30, 2023.

²The security that has been valued at zero on the “Schedule of investments” is considered to be Level 3 investments in this table.

As a result of utilizing international fair value pricing at June 30, 2023, a portion of the common stock in the portfolio was categorized as Level 2.

During the six months ended June 30, 2023, there were no transfers into or out of Level 3 investments. The Series’ policy is to recognize transfers into or out of Level 3 investments based on fair value at the beginning of the reporting period.

A reconciliation of Level 3 investments is presented when the Series has a significant amount of Level 3 investments at the beginning or end of the period in relation to the Series’ net assets. Management has determined not to provide a reconciliation of Level 3 investments as the Level 3 investments were not considered significant to the Series’ net assets at the beginning or end of the period. Management has determined not to provide additional disclosure on Level 3 inputs since the Level 3 investments were not considered significant to the Series’ net assets at the end of the period.

Notes to financial statements

4. Capital Shares

Transactions in capital shares were as follows:

5. Line of Credit

The Series, along with certain other funds in the Delaware Funds (Participants), is a participant in a $355,000,000 revolving line of credit (Agreement) intended to be used for temporary or emergency purposes as an additional source of liquidity to fund redemptions of investor shares. Under the Agreement, the Participants are charged an annual commitment fee of 0.15%, which is allocated across the Participants based on a weighted average of the respective net assets of each Participant. The Participants are permitted to borrow up to a maximum of one-third of their net assets under the Agreement. Each Participant is individually, and not jointly, liable for its particular advances, if any, under the line of credit. The line of credit available under the Agreement expires on October 30, 2023.

The Series had no amounts outstanding as of June 30, 2023, or at any time during the period then ended.

6. Derivatives

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

Foreign Currency Exchange Contracts — The Series may enter into foreign currency exchange contracts and foreign cross currency exchange contracts as a way of managing foreign exchange rate risk. The Series may enter into these contracts to fix the US dollar value of a security that it has agreed to buy or sell for the period between the date the trade was entered into and the date the security is delivered and paid for. The Series may also enter into these contracts to hedge the US dollar value of securities it already owns that are denominated in foreign currencies. In addition, the Series may enter into these contracts to facilitate or expedite the settlement of portfolio transactions. The change in value is recorded as an unrealized gain or loss. When the contract is closed, a realized gain or loss is recorded equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed.

The use of foreign currency exchange contracts and foreign cross currency exchange contracts does not eliminate fluctuations in the underlying prices of the securities, but does establish a rate of exchange that can be achieved in the future. Although foreign currency exchange contracts and foreign cross currency exchange contracts limit the risk of loss due to an unfavorable change in the value of the hedged currency, they also limit any potential gain that might result should the value of the currency change favorably. In addition, the Series could be exposed to risks if the counterparties to the contracts are unable to meet the terms of their contracts. The Series 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 Series and the counterparty and by the posting of collateral by the counterparty to the Series to cover the Series’ exposure to the counterparty.

During the six months ended June 30, 2023, the Series entered into foreign currency exchange contracts to facilitate or expedite the settlement of portfolio transactions.

During the six months ended June 30, 2023, the Series experienced net realized and unrealized gains or losses attributable to foreign currency holdings, which are disclosed on the “Statement of assets and liabilities” and “Statement of operations.”

The table below summarizes the average daily balance of derivative holdings by the Series during the six months ended June 30, 2023:

7. Securities Lending

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

Cash collateral received by the Series is generally invested in an individual separate account. The investment guidelines permit each separate account to hold certain securities that would be considered eligible securities for a money market fund. Cash collateral received is generally invested in government securities; certain obligations issued by government sponsored enterprises; repurchase agreements collateralized by US Treasury securities; obligations issued by the central government of any Organization for Economic Cooperation and Development (OECD) country or its agencies, instrumentalities, or establishments; obligations of supranational organizations; commercial paper, notes, bonds, and other debt obligations; certificates of deposit, time deposits, and other bank obligations; certain money market funds; and asset-backed securities. The Series 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 Series or, at the discretion of the lending agent, replace the loaned securities. The Series continues to record dividends or interest, as applicable, on the securities loaned and is subject to changes in value of the securities loaned that may occur during the term of the loan. The Series has the right under the Lending Agreement to recover the securities from the borrower on demand. With respect to security loans collateralized by non-cash collateral, the Series receives loan premiums paid by the borrower. With respect to security loans collateralized by cash collateral, the earnings from the collateral investments are shared among the Series, the security lending agent, and the borrower. The Series records security lending income net of allocations to the security lending agent and the borrower.

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

Notes to financial statements

Delaware VIP^® Trust — Delaware VIP Emerging Markets Series

7. Securities Lending (continued)

At June 30, 2023, the Series had no securities out on loan.

8. Credit and Market Risk

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

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

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

The Series invests a significant portion of its assets in the greater China region, which consists of Hong Kong, the People’s Republic of China, and Taiwan, among other countries. As a result, the Series’ investments in the region are particularly susceptible to risks in that region. Adverse events in any one country within the region may impact the other countries in the region or Asia as a whole. As a result, adverse events in the region will generally have a greater effect on the Series than if the Series were more geographically diversified, which could result in greater volatility in the Series’ net asset value and losses. Markets in the greater China region can experience significant volatility due to social, economic, regulatory, and political uncertainties.

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

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

The Series may invest up to 10% of its net assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A promulgated under the Securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair the Series from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. While maintaining oversight, the Board has delegated to DMC, the day-to-day functions of determining whether individual securities are liquid for purposes of the Series’ 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 Series’ 10% limit on investments in illiquid securities. Rule 144A securities have been identified on the “Schedule of investments.”

9. Contractual Obligations

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

10. New Regulatory Pronouncement

In October 2022, the Securities and Exchange Commission (SEC) adopted a rule and form amendments relating to tailored shareholder reports for mutual funds and ETFs; and fee information in investment company advertisements. The rule and form amendments will require mutual funds and ETFs to transmit streamlined shareholder reports that highlight key information to investors. The rule amendments will require that certain more in-depth information be made available online and available for delivery free of charge to investors on request. The amendments became effective in January 2023 and there is an 18-month transition period after the effective date of the amendment with a compliance date of July 2024.

11. Subsequent Events

Management has determined that no material events or transactions occurred subsequent to June 30, 2023, that would require recognition or disclosure in the Series’ financial statements.

Liquidity Risk Management Program

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

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

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

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

At a meeting of the Board held on May 23-25, 2023, the Program Administrator provided a written report to the Board addressing the Program’s operation and assessing the adequacy and effectiveness of its implementation for the period from April 1, 2022 through March 31, 2023. The report concluded that the Program is appropriately designed and effectively implemented and that it meets the requirements of Rule 22e-4 and the Series’ liquidity needs. The Series’ HLIM is set at an appropriate level and the Series complied with its HLIM at all times during the reporting period.

The Series files its complete schedule of portfolio holdings with the Securities and Exchange Commission (SEC) for the first and third quarters of each fiscal year on Form N-PORT. The Series’ Form N-PORT, as well as a description of the policies and procedures that the Series uses to determine how to vote proxies (if any) relating to portfolio securities, is available without charge (i) upon request, by calling 800 523-1918; and (ii) on the SEC’s website at sec.gov. In addition, a description of the policies and procedures that the Series uses to determine how to vote proxies (if any) relating to portfolio securities and the Schedule of Investments included in the Series’ most recent Form N-PORT are available without charge on the Series’ website at delawarefunds.com/vip/literature.

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

Disclosure of Series expenses

For the six-month period from January 1, 2023 to June 30, 2023 (Unaudited)

The investment objective of the Series is to seek capital appreciation.

As a shareholder of the Series, you incur ongoing costs, which may include management fees; distribution and service (12b-1) fees; and other Series expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Series and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire six-month period from January 1, 2023 to June 30, 2023.

Actual expenses

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

Hypothetical example for comparison purposes

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

Please note that the expenses shown in the table are meant to highlight your ongoing costs only. As a shareholder of the Series, you do not incur any transaction costs, such as sales charges (loads), redemption fees or exchange fees, but shareholders of other funds may incur such costs. Also, the fees related to the variable annuity investment or the deferred sales charge that could apply have not been included. Therefore, the second section of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. The Series’ expenses shown in the table reflect fee waivers in effect and assume reinvestment of all dividends and distributions.

Expense analysis of an investment of $1,000

In addition to the Series’ expenses reflected above, the Series also indirectly bears its portion of the fees and expenses of any investment companies (Underlying Funds) in which it invests. The table above does not reflect the expenses of any Underlying Funds.
