Strategy [Heading]	What are the Series’ principal investment strategies?
Strategy Narrative [Text Block]	Nomura VIP Growth and Income Series primarily invests in common stocks that offer the potential for capital growth, current income or both. The Series primarily invests in common stocks of large-size companies. The Series may also invest in mid- and small-size companies. The Series seeks to generate income by investing primarily in dividend paying companies. The Series may also own convertible securities. Convertible securities are usually preferred stocks or corporate bonds that can be exchanged for a set number of shares of common stock at a predetermined price. These securities offer higher appreciation potential than nonconvertible bonds and greater income potential than nonconvertible preferred stocks. The Series may also invest in real estate investment trusts (REITs) and income-generating equity securities. REITs are pooled investment vehicles that invest primarily in income-producing real estate or real estate-related loans or interests. Macquarie Investment Management Global Limited (MIMGL) serves as the Series’ sub-advisor and manages the Series’ assets. Using a systematic bottom-up approach, the Series seeks to select securities that have above-average yields coupled with a demonstrated business quality, as seen through superior profitability, balance sheet strength, earnings stability and corporate sustainability. Stocks also need to have reasonable company valuations relative to their current growth prospects, and their peer group. All of these factors give insight into the outlook for a company, and identify companies poised for sustainable growth. Sustainable growth, if it occurs, may result in price appreciation for the company’s stock.

Nomura VIP Growth Equity Series
Prospectus [Line Items]
Strategy [Heading]	What are the Series’ principal investment strategies?
Strategy Narrative [Text Block]	Nomura VIP Growth Equity Series seeks to achieve its objective by investing primarily in a portfolio of common stocks issued by large-capitalization, growth-oriented companies that the Manager believes have a competitively advantaged business model, thereby eluding competition, and have the ability to sustain growth over the long term beyond investors’ expectations. Under normal circumstances, the Series invests at least 80% of its net assets in large-capitalization companies, which typically are companies with market capitalizations of at least $10 billion at the time of acquisition. Growth-oriented companies are those whose earnings the Manager believes are likely to grow faster than the economy. The Series’ portfolio of assets is diversified. In selecting securities for the Series, the Manager begins its investment process by screening large-capitalization companies based on profitability (capital returns and margins) and growth (sales and earnings), while simultaneously utilizing fundamental analysis to assess any unique business attributes that validate those financial characteristics. The Manager uses a bottom-up (researching individual issuers) strategy in selecting securities for the Series. The Manager seeks to invest for the Series in companies that it believes possess a structural competitive advantage or durable market leadership position. The Manager looks for companies which serve large addressable markets with a demonstrated ability to sustain unit growth and high profitability. The Manager also seeks to invest in companies that it believes have improving growth prospects or improving levels of profitability and returns. A competitively advantaged business model can be defined by such factors as: brand loyalty, proprietary technology, cost structure, scale, exclusive access to data, or distribution advantages. Other factors considered include strength of management; environmental. social and governance (ESG) characteristics; level of competitive intensity; return of capital; strong balance sheets and cash flows; the threat of substitute products; and the interaction and bargaining power between a company, its customers, suppliers, and competitors. The Manager’s process for selecting stocks is based primarily on fundamental research, but does utilize quantitative analysis during the screening process. From a quantitative standpoint, the Manager concentrates on the level of profitability, capital intensity, cash flow and capital allocation measures, as well as earnings growth rates and valuations. The Manager’s fundamental research effort tries to identify those companies that it believes possess a sustainable competitive advantage, an important characteristic which typically enables a company to generate above-average levels of profitability and the ability to sustain growth over the long term. The Series typically holds a limited number of stocks (generally 35 to 50). Many of the companies in which the Series may invest have diverse operations, with products or services in foreign markets. Therefore, the Series may have indirect exposure to various foreign markets through investments in these companies, even if the Series is not invested directly in such markets. In general, the Manager may sell a security when, in the Manager’s opinion, a company experiences deterioration in its growth and/or profitability characteristics, or a fundamental breakdown of its sustainable competitive advantages. The Manager also may sell a security if it believes that the security no longer presents sufficient appreciation potential; this may be caused by, or be an effect of, changes in the industry or sector of the issuer, loss by the company of its competitive position, poor execution by management, the threat of technological disruption and/or poor use of resources. The Manager also may sell a security to reduce the Series’ holding in that security, to take advantage of what it believes are more attractive investment opportunities or to raise cash.

Strategy [Heading]	What are the Series’ principal investment strategies?
Strategy Narrative [Text Block]	Nomura VIP Small Cap Value Series invests primarily in investments of small companies whose stock prices, in the portfolio managers’ opinion, appear low relative to their underlying value or future potential. Among other factors, the Manager considers the financial strength of a company, its management, the prospects for its industry, and any anticipated changes within the company that might suggest a more favorable outlook going forward. The Manager focuses on free cash flow in its individual stock selection, seeking companies that the Manager believes have a sustainable ability to buy back shares, lower debt, and/or increase or initiate dividends. Under normal circumstances, at least 80% of the Series’ net assets, plus the amount of any borrowings for investment purposes, will be in investments of small-capitalization companies (80% policy). The Series considers small-capitalization companies to be companies with a market capitalization generally less than 3.5 times the dollar-weighted, median market capitalization of the Russell 2000^® Index at the time of purchase. The Series may invest up to 15% of its net assets in real estate investment trusts (REITs). The Series’ 80% policy is nonfundamental and may be changed without shareholder approval. Series shareholders would be given at least 60 days’ notice prior to any such change.

Prospectus [Line Items]
Strategy [Heading]	What are the Series’ principal investment strategies?
Strategy Narrative [Text Block]	Nomura VIP Opportunity Series invests primarily in mid- and small-size companies that the Series’ Manager believes offer attractive valuation and quality characteristics. Companies with attractive valuations are those that have a lower valuation than the company’s historical average valuation and a lower valuation than the company’s competitors. Companies with quality characteristics will make shareholder friendly use of its cash flow, which would include, but is not limited to: dividend payments or increases, share repurchases, and repayment of debt. The Series may also invest up to 15% of its net assets in real estate investment trusts (REITs). The Series may continue to hold stocks of mid-size companies that grow into larger companies and may also invest opportunistically in stocks of larger companies. The Series uses a “bottom-up” approach to selecting investments. The Series uses fundamental research to search for companies that the Manager believes have one or more of the following: a strong balance sheet; experienced management; and stocks that are attractively priced. The Series attempts to stay broadly diversified, but it may emphasize certain industry sectors based upon economic and market conditions. The Series may sell a stock if it becomes fully valued, its fundamentals have deteriorated or alternative investments become more attractive. The Series may also sell a stock if it grows into a large, well-established company, although it may also continue to hold such a stock irrespective of its size.

Nomura VIP Fund for Income Series
Prospectus [Line Items]
Strategy [Heading]	What are the Series’ principal investment strategies?
Strategy Narrative [Text Block]	Nomura VIP Fund for Income Series primarily invests in corporate bonds rated at the time of purchase lower than BBB- by Standard & Poor’s Financial Services LLC (S&P) or lower than Baa3 by Moody’s Investors Service, Inc. (Moody’s), or similarly rated by another nationally recognized statistical rating organization (NRSRO) or, if unrated, determined by the Manager and Nomura Corporate Research and Asset Management Inc. (the “Sub-Advisor,” and together with the Manager, the “Management Team”) to be of comparable quality. These are commonly known as high yield bonds or “junk bonds” and involve greater risks than investment grade bonds. The Series may also invest in unrated bonds that the Management Team judges to be of comparable quality. Unrated bonds may be more speculative in nature than rated bonds. The Series may also invest in US and foreign government securities and corporate bonds of foreign issuers. The Series may invest in bonds of any maturity or duration. The Series may invest up to 40% of its net assets in foreign securities; however, the Series’ total non-US-dollar currency exposure will be limited, in the aggregate, to no more than 25% of the Series’ net assets, and investments in emerging market securities will be limited to 20% of the Series’ net assets. Emerging market countries include those currently considered to be developing or emerging countries by the World Bank, the United Nations, the countries’ governments, or in the judgment of the Management Team. In selecting bonds for the portfolio, the Management Team evaluates the income provided by the bond and the bond’s appreciation potential as well as the issuer’s ability to make income and principal payments.

Nomura VIP Investment Grade Series
Prospectus [Line Items]
Strategy [Heading]	What are the Series’ principal investment strategies?
Strategy Narrative [Text Block]	Under normal circumstances, Nomura VIP Investment Grade Series invests at least 80% of its net assets (plus any borrowings for investment purposes) in investment grade debt securities. Investment grade debt securities include those that are rated within the four highest ratings categories by Moody’s Investors Service, Inc. (Moody’s) or Standard & Poor’s Financial Services LLC (S&P) or that are unrated but determined by the Manager to be of equivalent quality. The Series primarily invests in investment grade US corporate bonds. The Series may also invest in other investment grade securities, including securities issued or guaranteed by the US Government or US Government-sponsored enterprises (some of which are not backed by the full faith and credit of the US Government) and investment grade mortgage-backed and other asset-backed securities. In making investment decisions, the Manager considers the outlook for interest rates, economic forecasts and market conditions, credit ratings, and its own analysis of an issuer’s financial condition. The Manager attempts to stay broadly diversified, but may emphasize certain industries based on its outlook. The Manager usually will sell a security when it shows deteriorating fundamentals, it falls short of the portfolio manager’s expectations, or a more attractive investment is available. The Manager will not necessarily sell an investment if its rating is reduced. To a lesser extent, the Series also invests in high yield, below investment grade corporate bonds (commonly known as “high yield” or “junk bonds”). High yield bonds include bonds that are rated below Baa3 by Moody’s or below BBB- by S&P as well as unrated bonds that are determined by the Manager to be of equivalent quality. The Manager will consider ratings assigned by ratings agencies in selecting high yield bonds, but relies principally on its own research and investment analysis. In managing its portion of the Series, the Manager focuses on investments it believes can generate attractive and consistent income. The Manager may sell a bond when it shows deteriorating fundamentals or it falls short of the Manager’s expectations. In addition, the Manager may also invest in active or passive exchange-traded funds (ETFs) that could expose the Series to high yield securities. The Series may invest in securities of any maturity or duration, but may adjust its average portfolio weighted duration or maturity in anticipation of interest rate changes. For example, if the Series expects interest rates to rise, it may seek to reduce its average portfolio weighted duration and maturity. The Series may also invest in US Treasury futures and options on US Treasury futures to hedge against changes in interest rates. Additionally, from time to time, in pursuing its investment strategies, the Series may hold significant investments (25% or more of its assets) in a specific market sector, including the financials sector.

Strategy [Heading]	What are the Series’ principal investment strategies?
Strategy Narrative [Text Block]	Under normal circumstances, Nomura VIP Limited Duration Bond Series will invest at least 80% of its net assets (plus any borrowings for investment purposes) in investment grade bonds (80% policy). For purposes of this 80% policy, investment grade bonds also include other investment grade fixed-income securities. Investment grade debt securities include those that are rated within the four highest ratings categories by Moody’s Investors Service, Inc. (Moody’s) or Standard & Poor’s Financial Services LLC (S&P) or that are unrated but determined by the Manager to be of equivalent quality. The Series will maintain an average effective duration from one to three years. The Manager will determine how much of the Series’ assets to allocate among the different types of fixed income securities in which the Series may invest based on the Manager’s evaluation of economic and market conditions and its assessment of the returns and potential for appreciation that can be achieved from various sectors of the fixed income market. The corporate debt obligations in which the Series may invest include bonds, notes, debentures, and commercial paper of US companies and, subject to the limitations described below, non-US companies. The Series may also invest in a variety of securities that are issued or guaranteed as to the payment of principal and interest by the US government, and by various agencies or instrumentalities, which have been established or are sponsored by the US government, and, subject to the limitations described below, securities issued by foreign governments. Additionally, the Series may invest in mortgage-backed securities issued or guaranteed by the US government, its agencies or instrumentalities, government-sponsored corporations, and mortgage-backed securities issued by certain private, nongovernment entities. The Series may also invest in securities that are backed by assets such as receivables on home equity and credit card loans, automobile, mobile home, recreational vehicle and other loans, wholesale dealer floor plans, and leases. The Series may invest up to 20% of its net assets in below-investment-grade securities (also known as high yield or “junk” bonds). The Series may also invest up to 20% of its net assets in foreign securities, including up to 10% of its net assets in securities of issuers located in emerging markets. The Series’ total non-US dollar currency will be limited, in the aggregate, to no more than 10% of its net assets. The Series may use a wide range of derivatives instruments, typically including options, futures contracts, options on futures contracts, forward foreign currency contracts, and swaps. The Series will use derivatives for both hedging and nonhedging purposes. For example, the Series may invest in: futures and options to manage duration and for defensive purposes, such as to protect gains or hedge against potential losses in the portfolio without actually selling a security, or to stay fully invested; forward foreign currency contracts to manage foreign currency exposure; interest rate swaps to neutralize the impact of interest rate changes; credit default swaps to hedge against a credit event, to manage credit exposure, or to enhance total return; and index swaps to enhance return or to effect diversification. The Series will not use derivatives for reasons inconsistent with its investment objective and will limit its investments in derivatives instruments to 20% of its net assets.

Nomura VIP Emerging Markets Series
Prospectus [Line Items]
Strategy [Heading]	What are the Series’ principal investment strategies?
Strategy Narrative [Text Block]	Nomura VIP Emerging Markets Series invests primarily in a broad range of equity securities of companies located in emerging market countries. Emerging market countries include those currently considered to be developing by the World Bank, the United Nations, or the countries’ governments. These countries typically are located in the Asia-Pacific region, Eastern Europe, the Middle East, Central America, South America, and Africa. Under normal circumstances, at least 80% of the Series’ net assets, plus the amount of any borrowings for investment purposes, will be invested in emerging market issuers (80% policy). The Series may invest in companies of any size and may invest more than 25% of its total assets in the securities of issuers located in the same country. The Series will primarily invest in countries included in the MSCI Emerging Markets Index. Benchmark weightings may result in the Series investing over 25% in any one country. The Series may invest significantly in the Asia-Pacific region, which consists of Hong Kong, the People’s Republic of China, Republic of Korea, Taiwan, and India, among other countries. As a result, the Series’ investments in the region may be particularly susceptible to risks in that region. Although the Series invests primarily in companies from countries considered to be emerging, the Series will also invest in companies that are not in emerging countries: (1) if the Manager believes that the performance of a company or its industry will be influenced by opportunities in the emerging markets; (2) to maintain exposure to industry segments where the Manager believes there are not satisfactory investment opportunities in emerging countries; and (3) if the Manager believes there is the potential for significant benefit to the Series. The Manager believes that although market price and intrinsic business value are positively correlated in the long run, short-term divergences can emerge. The Series seeks to take advantage of these divergences through a fundamental, bottom-up approach. The Series invests in securities of companies that the Manager believes have durable franchises when they are trading at a discount to the Manager’s intrinsic value estimate for that security. The Manager defines durable franchises as those companies with potential to earn excess returns above their cost of capital over the long run. Durability analysis involves identification of a company’s source of competitive advantage and the ability of its management to maximize its return potential. The Manager prefers companies with large market opportunities in which to deploy capital, providing opportunities to grow faster than the overall economy. Intrinsic value assessment is quantitatively determined through a variety of valuation methods including discounted cash flow, replacement cost, private market transaction, and multiples analysis. The Series’ 80% policy is nonfundamental and may be changed without shareholder approval. Series shareholders would be given at least 60 days’ notice prior to any such change.

Nomura VIP Total Return Series
Prospectus [Line Items]
Strategy [Heading]	What are the Series’ principal investment strategies?
Strategy Narrative [Text Block]	Nomura VIP Total Return Series allocates its assets among stocks (US and foreign companies), bonds and money market instruments. The Series does not use a fixed formula for allocating investments between stocks and bonds. While the percentage of assets allocated to each asset class is flexible rather than fixed, the Series normally invests at least 50% of its net assets in stocks, stock equivalents, and convertible securities with the remainder in bonds, cash and money market instruments. The percentage allocations within the above ranges may change due to, among other things, market fluctuations or reallocation decisions by the Manager. The Manager uses a dynamic asset-allocation framework to determine the proportion of the Series’ assets that will be allocated to the various asset classes, based on the market assessment and portfolio risk contribution for such asset classes. Reallocations outside of the above ranges are expected to occur infrequently. The Series may also invest in high yield, below investment grade corporate bonds (commonly known as high yield or “junk bonds”). High yield bonds include bonds that are rated below Baa3 by Moody’s Investors Service, Inc. (Moody’s) or below BBB- by Standard & Poor’s Financial Services LLC (S&P) as well as unrated bonds that are determined by the Manager to be of equivalent quality. The Manager will consider ratings assigned by ratings agencies in selecting high yield bonds but relies principally on its own research and investment analysis. In managing its portion of the Series, the Manager primarily focuses on investments it believes can generate attractive and consistent income. The Manager may sell a bond when it shows deteriorating fundamentals or it falls short of the Manager’s expectations. The Series may invest in credit-linked securities, provided that no more than 10% of the Series’ net assets are invested in credit-linked securities. The Series may also invest in real estate related companies and real estate investment trusts (REITs). In connection with its dynamic asset-allocation framework, the Manager will also manage a tactical/completion sleeve and such sleeve will typically vary from 0% to 20% of the Series’ total assets and primarily hold derivatives and exchange-traded funds (ETFs). The Series may use a wide range of derivatives instruments, typically including forward foreign currency contracts, options, futures contracts, options on futures contracts, and credit default swaps. The Series will use derivatives for both hedging and non-hedging purposes; as a substitute for purchasing or selling securities; and to manage the Series’ portfolio characteristics. For example, the Series may invest in: futures and options to manage duration and for defensive purposes, such as to protect gains or hedge against potential losses in the portfolio without actually selling a security, or to stay fully invested; forward foreign currency contracts to manage foreign currency exposure; and credit default swaps to hedge against a credit event, to gain exposure to certain securities or markets, or to enhance total return. The Series’ 80% policy is nonfundamental and may be changed without shareholder approval. Series shareholders would be given at least 60 days’ notice prior to any such change.

Under normal circumstances, Nomura VIP Investment Grade Series invests at least 80% of its net assets (plus any borrowings for investment purposes) in investment grade debt securities.

The Manager may sell a bond when it shows deteriorating fundamentals or it falls short of the Manager’s expectations. In addition, the Manager may also invest in active or passive exchange-traded funds (ETFs) that could expose the Series to high yield securities.

The Series may invest in securities of any maturity or duration, but may adjust its average portfolio weighted duration or maturity in anticipation of interest rate changes. For example, if the Series expects interest rates to rise, it may seek to reduce its average portfolio weighted duration and maturity. The Series may also invest in US Treasury futures and options on US Treasury futures to hedge against changes in interest rates.

Additionally, from time to time, in pursuing its investment strategies, the Series may hold significant investments (25% or more of its assets) in a specific market sector, including the financials sector.

Strategy Narrative [Text Block]

Under normal circumstances, Nomura VIP Limited Duration Bond Series will invest at least 80% of its net assets (plus any borrowings for investment purposes) in investment grade bonds (80% policy). For purposes of this 80% policy, investment grade bonds also include other investment grade fixed-income securities.

Investment grade debt securities include those that are rated within the four highest ratings categories by Moody’s Investors Service, Inc. (Moody’s) or Standard & Poor’s Financial Services LLC (S&P) or that are unrated but determined by the Manager to be of equivalent quality. The Series will maintain an average effective duration from one to three years. The Manager will determine how much of the Series’ assets to allocate among the different types of fixed income securities in which the Series may invest based on the Manager’s evaluation of economic and market conditions and its assessment of the returns and potential for appreciation that can be achieved from various sectors of the fixed income market.

The corporate debt obligations in which the Series may invest include bonds, notes, debentures, and commercial paper of US companies and, subject to the limitations described below, non-US companies. The Series may also invest in a variety of securities that are issued or guaranteed as to the payment of principal and interest by the US government, and by various agencies or instrumentalities, which have been established or are sponsored by the US government, and, subject to the limitations described below, securities issued by foreign governments.

Additionally, the Series may invest in mortgage-backed securities issued or guaranteed by the US government, its agencies or instrumentalities, government-sponsored corporations, and mortgage-backed securities issued by certain private, nongovernment entities. The Series may also invest in securities that are backed by assets such as receivables on home equity and credit card loans, automobile, mobile home, recreational vehicle and other loans, wholesale dealer floor plans, and leases.

The Series may invest up to 20% of its net assets in below-investment-grade securities (also known as high yield or “junk” bonds).

The Series may also invest up to 20% of its net assets in foreign securities, including up to 10% of its net assets in securities of issuers located in emerging markets. The Series’ total non-US dollar currency will be limited, in the aggregate, to no more than 10% of its net assets.

The Series may use a wide range of derivatives instruments, typically including options, futures contracts, options on futures contracts, forward foreign currency contracts, and swaps. The Series will use derivatives for both hedging and nonhedging purposes. For example, the Series may invest in: futures and options to manage duration and for defensive purposes, such as to protect gains or hedge against potential losses in the portfolio without actually selling a security, or to stay fully invested; forward foreign currency contracts to manage foreign currency exposure; interest rate swaps to neutralize the impact of interest rate changes; credit default swaps to hedge against a credit event, to manage credit exposure, or to enhance total return; and index swaps to enhance return or to effect diversification. The Series will not use derivatives for reasons inconsistent with its investment objective and will limit its investments in derivatives instruments to 20% of its net assets.

Nomura VIP Emerging Markets Series

What are the Series’ principal investment strategies?

Strategy Narrative [Text Block]

Nomura VIP Emerging Markets Series invests primarily in a broad range of equity securities of companies located in emerging market countries. Emerging market countries include those currently considered to be developing by the World Bank, the United Nations, or the countries’ governments. These countries typically are located in the Asia-Pacific region, Eastern Europe, the Middle East, Central America, South America, and Africa. Under normal circumstances, at least 80% of the Series’ net assets, plus the amount of any borrowings for investment purposes, will be invested in emerging market issuers (80% policy). The Series may invest in companies of any size and may invest more than 25% of its total assets in the securities of issuers located in the same country. The Series will primarily invest in countries included in the MSCI Emerging Markets Index. Benchmark weightings may result in the Series investing over 25% in any one country. The Series may invest significantly in the Asia-Pacific region, which consists of Hong Kong, the People’s Republic of China, Republic of Korea, Taiwan, and India, among other countries. As a result, the Series’ investments in the region may be particularly susceptible to risks in that region.

Although the Series invests primarily in companies from countries considered to be emerging, the Series will also invest in companies that are not in emerging countries: (1) if the Manager believes that the performance of a company or its industry will be influenced by opportunities in the emerging markets; (2) to maintain exposure to industry segments where the Manager believes there are not satisfactory investment opportunities in emerging countries; and (3) if the Manager believes there is the potential for significant benefit to the Series.

The Manager believes that although market price and intrinsic business value are positively correlated in the long run, short-term divergences can emerge. The Series seeks to take advantage of these divergences through a fundamental, bottom-up approach. The Series invests in securities of companies that the Manager believes have durable franchises when they are trading at a discount to the Manager’s intrinsic value estimate for that security.

The Manager defines durable franchises as those companies with potential to earn excess returns above their cost of capital over the long run. Durability analysis involves identification of a company’s source of competitive advantage and the ability of its management to maximize its return potential. The Manager prefers companies with large market opportunities in which to deploy capital, providing opportunities to grow faster than the overall economy.

Intrinsic value assessment is quantitatively determined through a variety of valuation methods including discounted cash flow, replacement cost, private market transaction, and multiples analysis.

The Series’ 80% policy is nonfundamental and may be changed without shareholder approval. Series shareholders would be given at least 60 days’ notice prior to any such change.

What are the Series’ principal investment strategies?

Strategy Narrative [Text Block]

Nomura VIP Total Return Series allocates its assets among stocks (US and foreign companies), bonds and money market instruments. The Series does not use a fixed formula for allocating investments between stocks and bonds. While the percentage of assets allocated to each asset class is flexible rather than fixed, the Series normally invests at least 50% of its net assets in stocks, stock equivalents, and convertible securities with the remainder in bonds, cash and money market instruments.

The percentage allocations within the above ranges may change due to, among other things, market fluctuations or reallocation decisions by the Manager. The Manager uses a dynamic asset-allocation framework to determine the proportion of the Series’ assets that will be allocated to the various asset classes, based on the market assessment and portfolio risk contribution for such asset classes. Reallocations outside of the above ranges are expected to occur infrequently.

The Series may also invest in high yield, below investment grade corporate bonds (commonly known as high yield or “junk bonds”). High yield bonds include bonds that are rated below Baa3 by Moody’s Investors Service, Inc. (Moody’s) or below BBB- by Standard & Poor’s Financial Services LLC (S&P) as well as unrated bonds that are determined by the Manager to be of equivalent quality. The Manager will consider ratings assigned by ratings agencies in selecting high yield bonds but relies principally on its own research and investment analysis. In managing its portion of the Series, the Manager primarily focuses on investments it believes can generate attractive and consistent income. The Manager may sell a bond when it shows deteriorating fundamentals or it falls short of the Manager’s expectations. The Series may invest in credit-linked securities, provided that no more than 10% of the Series’ net assets are invested in credit-linked securities.

The Series may also invest in real estate related companies and real estate investment trusts (REITs).

In connection with its dynamic asset-allocation framework, the Manager will also manage a tactical/completion sleeve and such sleeve will typically vary from 0% to 20% of the Series’ total assets and primarily hold derivatives and exchange-traded funds (ETFs).

The Series may use a wide range of derivatives instruments, typically including forward foreign currency contracts, options, futures contracts, options on futures contracts, and credit default swaps. The Series will use derivatives for both hedging and non-hedging purposes; as a substitute for purchasing or selling securities; and to manage the Series’ portfolio characteristics. For example, the Series may invest in: futures and options to manage duration and for defensive purposes, such as to protect gains or hedge against potential losses in the portfolio without actually selling a security, or to stay fully invested; forward foreign currency contracts to manage foreign currency exposure; and credit default swaps to hedge against a credit event, to gain exposure to certain securities or markets, or to enhance total return.

The Series’ 80% policy is nonfundamental and may be changed without shareholder approval. Series shareholders would be given at least 60 days’ notice prior to any such change.
