What are the Series' fees and expenses?

Example

This example is intended to help you compare the cost of investing in the Series with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Series for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and reflects the Manager's expense waivers and reimbursements for the 1-year contractual period and the total operating expenses without waivers for years 2 through 10. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Summary prospectus

Portfolio turnover

The Series pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Series shares are held in a taxable account. These costs, which are not reflected in the annual series operating expenses or in the example, affect the Series' performance. During the most recent fiscal year, the Series' portfolio turnover rate was 15% of the average value of its portfolio.

What are the Series' principal investment strategies?

Nomura VIP Smid Cap Core Series  seeks to achieve its objective by investing primarily in various types of equity securities of small- and mid-capitalization companies that the Manager believes have the greatest potential for capital appreciation. Under normal circumstances, at least 80% of the Series' net assets will be invested, at the time of purchase, in common stocks of small- and mid-capitalization companies. For purposes of this Series, small-capitalization companies typically are companies with market capitalizations similar to those of issuers included in the Russell 2500^TM Index at the time of purchase and mid-capitalization companies are those within the market capitalization range of the Russell Midcap^® Index at the time of purchase.

The Manager researches individual companies and analyzes economic and market conditions, seeking to identify the securities or market sectors that it believes are the best investments for the Series. The following are descriptions of how the portfolio management team pursues the Series' investment objective. The Manager strives to identify stocks of small companies that it believes offer above-average opportunities for long-term price appreciation based on: (1) attractive valuations, (2) growth prospects, and (3) strong cash flow. The Series employs bottom-up (stock-by-stock) security selection utilizing quantitative screens, fundamental research, and risk control to evaluate stocks based on both growth and value characteristics. The Manager typically uses a quantitative screen that ranks the attractiveness of an investment based on a combination of valuation measures, earnings expectations, cash flow, and balance-sheet quality. In further evaluating the attractiveness of an investment, the Manager considers factors such as business conditions in the company's industry and its competitive position in that industry. The Manager conducts fundamental research on certain investments, which often includes reviewing US Securities and Exchange Commission (SEC) filings, examining financial statements, and meeting with top-level company executives. When constructing the portfolio, the Manager applies controls to ensure the portfolio has risk characteristics that it deems acceptable. These characteristics include, but are not limited to, size, valuation, growth, yield, and earnings consistency. This risk profile is then compared to the benchmark index to ensure the portfolio does not have any unintended risk exposure.

What are the principal risks of investing in the Series?

Investing in any mutual fund involves the risk that you may lose part or all of the money you invest. Over time, the value of your investment in the Series will increase and decrease according to changes in the value of the securities in the Series' portfolio. An investment in the Series may not be appropriate for all investors. The Series' principal risks include:

Market risk - The risk that all or a majority of the securities in a certain market - such as the stock or bond market - will decline in value because of factors such as adverse political or economic conditions, future expectations, investor confidence, or heavy institutional selling.

Company size risk - The risk that investments in small- and/or medium-sized companies may be more volatile than those of larger companies because of limited financial resources or dependence on narrow product lines.

Industry and sector risk - The risk that the value of securities in a particular industry or sector (such as industrials) will decline because of changing expectations for the performance of that industry or sector.

Industrials sector risk - The risk that the value of a series' shares will be affected by factors particular to the industrials and related sectors (such as government regulation) and may fluctuate more widely than that of a series that invests in a broad range of sectors.

Interest rate risk - The risk that securities will decrease in value if interest rates rise. The risk is generally associated with bonds; however, because small- and medium-sized companies and companies in the real estate sector often borrow money to finance their operations, they may be adversely affected by rising interest rates. A series may be subject to a greater risk of rising interest rates when interest rates are low or inflation rates are high or rising.

Liquidity risk - The possibility that investments cannot be readily sold within seven calendar days at approximately the price at which a series has valued them.

Government and regulatory risk - The risk that governments or regulatory authorities may take actions that could adversely affect various sectors of the securities markets and affect series performance.

Redemption risk - If investors redeem more shares of a series than are purchased for an extended period of time, a series may be required to sell securities without regard to the investment merits of such actions. This could decrease a series' asset base, potentially resulting in a higher expense ratio.

2

Active management and selection risk - The risk that the securities selected by a series' management will underperform the markets, the relevant indices, or the securities selected by other funds with similar investment objectives and investment strategies. The securities and sectors selected may vary from the securities and sectors included in the relevant index.

Summary prospectus

Who manages the Series?

Investment manager

Delaware Management Company, a series of Nomura  Investment Management Business Trust (a Delaware statutory trust)

Employees of the Manager's  affiliates outside the US participate in the management of certain funds as "associated persons" of the Manager  under the Manager's oversight, in accordance with SEC guidance as to "participating affiliate" arrangements. These associated persons may, on behalf of the Manager, provide discretionary investment management services, trading, research and related services directly or indirectly to the Series.

Purchase and redemption of Series shares

Shares are sold, directly or indirectly, to separate accounts of life insurance companies at net asset value (NAV). Please refer to the variable annuity or variable life insurance product contract prospectus for more information about the purchase and redemption of shares.

Tax information

The dividends and distributions paid from the Series to the insurance company separate accounts will consist of ordinary income, capital gains, or some combination of both. Because shares of the Series must be purchased through separate accounts used to fund variable annuity contracts or variable life insurance contracts (variable contracts), such dividends and distributions will be exempt from current taxation by contract holders if left to accumulate within a separate account. You should refer to your variable contract prospectus for more information on these tax consequences.

Payments to broker/dealers and other financial intermediaries

If you purchase shares of the Series through a broker/dealer or other financial intermediary (such as an insurance company), the  Series and its related companies may pay the intermediary for the sale of Series shares and related services. These payments may create a conflict of interest by influencing the broker/dealer or other intermediary and your salesperson to recommend the Series over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
