Nomura VIP Fund for Income Series \| Restricted securities risk [Member]

These securities include private placements or other unregistered securities, such as “Rule 144A Securities”, which are securities that may be sold only to qualified institutional buyers pursuant to the Securities Act of 1933, as amended (1933 Act). Privately placed securities, Rule 144A securities and other restricted securities may have the effect of increasing the level of series illiquidity to the extent a series finds it difficult to sell these securities when the Manager believes it is desirable to do so, especially under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, and the prices realized could be less than those originally paid, or less than the fair market value. At times, the illiquidity of the market, as well as the lack of publicly available information regarding these securities also may make it difficult to determine the fair market value of such securities for purposes of computing the NAV of a series.
Nomura VIP Fund for Income Series \| New issue risk [Member]

Nomura VIP Fund for Income Series \| Deferred payment securities risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Deferred payment securities risk — These securities may be subject to greater price fluctuations when interest rates change than securities that currently pay interest.

Nomura VIP Fund for Income Series \| Payment-in-kind securities risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Payment-in-kind securities risk — Payment-in-kind securities defer cash interest payments by treating them as additional principal. This results in higher total debt and the potential for increased default risk of the issuer.

Nomura VIP Fund for Income Series \| Loans and Other Direct Indebtedness Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Loans and other direct indebtedness risk — The risk that a series 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 and the lending institution. A series’ ability to sell its loans or to realize their full value upon sale may also be impaired due to the lack of an active trading market, irregular trading activity, wide bid/ask spreads, contractual restrictions, and extended trade settlement periods. In addition, certain loans in which a series invests may not be considered securities. A series therefore may not be able to rely upon the anti-fraud provisions of the federal securities laws with respect to these investments.
Nomura VIP Fund for Income Series \| Credit risk [Member]

Nomura VIP Fund for Income Series \| Interest rate risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Interest rate risk — The risk that the prices of bonds and other fixed income securities will increase as interest rates fall and decrease as interest rates rise. Interest rate changes are influenced by a number of factors, such as government policy, monetary policy, inflation expectations, and the supply and demand of bonds. Bonds and other fixed income securities with longer maturities or duration generally are more sensitive to interest rate changes. 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.
Nomura VIP Fund for Income Series \| High Yield (Junk) Bond Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	High yield (junk) bond risk — The risk that high yield securities, commonly known as “junk bonds,” are subject to reduced creditworthiness of issuers, increased risk of default, and a more limited and less liquid secondary market.

Securities of issuers in emerging markets may be subject to greater risks than securities of issuers in more developed foreign markets because, among other things, emerging markets may have less stable political and economic environments. In addition, there often is substantially less publicly available information about issuers and such information tends to be of a lesser quality. Economic markets and structures tend to be less mature and diverse and the securities markets may also be smaller, less liquid, and subject to greater price volatility.
Nomura VIP Fund for Income Series \| Redemption risk [Member]
Prospectus [Line Items]
Risk [Text Block]	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.

Nomura VIP Investment Grade Series \| Mortgage-Backed and Asset-Backed Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Mortgage-backed and asset-backed securities risk — Mortgage-backed and asset-backed securities, like other fixed income securities, are subject to credit risk and interest rate risk, and may also be subject to prepayment risk and extension risk. Prepayment risk is the risk that the principal on mortgage-backed or asset-backed securities may be prepaid at any time, which will reduce the yield and market value of the securities and may cause the series to reinvest the proceeds in lower yielding securities. Extension risk is the risk that principal on mortgage-backed or asset-backed securities will be repaid more slowly than expected, which may reduce the proceeds available for reinvestment in higher yielding securities. In addition, mortgage-backed and asset-backed securities may decline in value, become more volatile, face difficulties in valuation, or experience reduced liquidity due to changes in interest rates or general economic conditions. Certain mortgage-backed or asset-backed securities, such as collateralized mortgage obligations, real estate mortgage investment conduits, and stripped mortgage-backed securities, may be more susceptible to these risks than other mortgage-backed, asset-backed, or fixed-income securities.

Nomura VIP Investment Grade Series \| Derivatives Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Derivatives risk — Derivatives contracts, such as futures, forward foreign currency contracts, options, and swaps, may involve additional expenses (such as the payment of premiums) and are subject to significant loss if a security, index, reference rate, or other asset or market factor to which a derivatives contract is associated, moves in an unanticipated direction. When used for hedging, the change in value of the derivatives instrument may also not correlate specifically with the currency, rate, or other risk being hedged, in which case a series may not realize the intended benefits. Derivatives contracts are also subject to the risk that the counterparty may fail to perform its obligations under the contract due to, among other reasons, financial difficulties (such as a bankruptcy or reorganization).

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.
Nomura VIP Emerging Markets Series \| Focused portfolio risk
Prospectus [Line Items]
Risk [Text Block]	Focused portfolio risk — Increases in the value of certain investments made by the Series may result in the Series holding a substantial percentage of its assets in a limited number of securities, as is the case as of the date of this prospectus. As a result, the Series may be exposed to greater risk and volatility than funds with a more diversified portfolio. A decline in the value of any significant holding could have a material adverse effect on the Series’ net asset value and performance. This risk is further magnified if two or more of the Series’ large holdings are closely correlated, as is the case as of the date of this prospectus. In such cases, a single negative event or market development could cause simultaneous declines in multiple holdings, leading to greater losses for the Series and its shareholders.
Nomura VIP Emerging Markets Series \| Government and Regulatory Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	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.
Nomura VIP Emerging Markets Series \| Industry and sector risk
Prospectus [Line Items]
Risk [Text Block]	Industry and sector risk — The risk that the value of securities in a particular industry or sector (such as information technology) will decline because of changing expectations for the performance of that industry or sector.
Nomura VIP Emerging Markets Series \| Growth stock risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Growth stock risk — Growth stocks 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.
Nomura VIP Emerging Markets Series \| Limited number of securities risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Limited number of securities risk — The possibility that a single security’s increase or decrease in value may have a greater impact on a series’ value and total return because the series may hold larger positions in fewer securities than other series. In addition, a series that holds a limited number of securities may be more volatile than those series that hold a greater number of securities.
Nomura VIP Emerging Markets Series \| Foreign and Emerging Markets Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Foreign and emerging markets risk — The risk that investments in foreign securities (particularly those of issuers in emerging markets) may be adversely affected by political instability; changes in currency exchange rates; inefficient markets and higher transaction costs; foreign economic conditions; the imposition of economic or trade sanctions; or inadequate or different regulatory and accounting standards. Securities of issuers in emerging markets may be subject to greater risks than securities of issuers in more developed foreign markets because, among other things, emerging markets may have less stable political and economic environments. In addition, there often is substantially less publicly available information about issuers and such information tends to be of a lesser quality. Economic markets and structures tend to be less mature and diverse and the securities markets may also be smaller, less liquid, and subject to greater price volatility.
Nomura VIP Emerging Markets Series \| Company size risk [Member]
Prospectus [Line Items]
Risk [Text Block]	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.
Nomura VIP Emerging Markets Series \| Market Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	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.
Nomura VIP Emerging Markets Series \| Liquidity Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	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.
Nomura VIP Emerging Markets Series \| Active management and selection risk [Member]
Prospectus [Line Items]
Risk [Text Block]	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.
Nomura VIP Total Return Series \| Risk Lose Money [Member]
Prospectus [Line Items]
Risk [Text Block]	Investing in any mutual fund involves the risk that you may lose part or all of the money you invest.

An investment in the Series may not be appropriate for all investors.
Nomura VIP Total Return Series \| Credit risk [Member]
Prospectus [Line Items]

Nomura VIP Total Return Series \| Interest rate risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Interest rate risk — The risk that the prices of bonds and other fixed income securities will increase as interest rates fall and decrease as interest rates rise. Interest rate changes are influenced by a number of factors, such as government policy, monetary policy, inflation expectations, and the supply and demand of bonds. Bonds and other fixed income securities with longer maturities or duration generally are more sensitive to interest rate changes. 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.
Nomura VIP Total Return Series \| High Yield (Junk) Bond Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	High yield (junk) bond risk — The risk that high yield securities, commonly known as “junk bonds,” are subject to reduced creditworthiness of issuers, increased risk of default, and a more limited and less liquid secondary market. High yield securities may also be subject to greater price volatility and risk of loss of income and principal than are higher-rated securities.
Nomura VIP Total Return Series \| Mortgage-Backed and Asset-Backed Securities Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Mortgage-backed and asset-backed securities risk — Mortgage-backed and asset-backed securities, like other fixed income securities, are subject to credit risk and interest rate risk, and may also be subject to prepayment risk and extension risk. Prepayment risk is the risk that the principal on mortgage-backed or asset-backed securities may be prepaid at any time, which will reduce the yield and market value of the securities and may cause the series to reinvest the proceeds in lower yielding securities. Extension risk is the risk that principal on mortgage-backed or asset-backed securities will be repaid more slowly than expected, which may reduce the proceeds available for reinvestment in higher yielding securities. In addition, mortgage-backed and asset-backed securities may decline in value, become more volatile, face difficulties in valuation, or experience reduced liquidity due to changes in interest rates or general economic conditions. Certain mortgage-backed or asset-backed securities, such as collateralized mortgage obligations, real estate mortgage investment conduits, and stripped mortgage-backed securities, may be more susceptible to these risks than other mortgage-backed, asset-backed, or fixed-income securities.

Nomura VIP Total Return Series \| Exchange-traded fund risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Exchange-traded fund risk — The risks of investing in an ETF typically reflect the risks of the instruments in which the ETF invests. Because ETFs are investment companies, a series will bear its proportionate share of the fees and expenses of an investment in an ETF. As a result, a series’ expenses may be higher and performance may be lower.

Nomura VIP Total Return Series \| Derivatives Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Derivatives risk — Derivatives contracts, such as futures, forward foreign currency contracts, options, and swaps, may involve additional expenses (such as the payment of premiums) and are subject to significant loss if a security, index, reference rate, or other asset or market factor to which a derivatives contract is associated, moves in an unanticipated direction. When used for hedging, the change in value of the derivatives instrument may also not correlate specifically with the currency, rate, or other risk being hedged, in which case a series may not realize the intended benefits. Derivatives contracts are also subject to the risk that the counterparty may fail to perform its obligations under the contract due to, among other reasons, financial difficulties (such as a bankruptcy or reorganization).
