Prospectus [Line Items]
Strategy [Heading]	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	To pursue its objective, under normal conditions, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in bonds, debentures and other fixed income securities. The Fund may invest a substantial portion of its net assets in high-yield securities (commonly referred to as “below investment grade” or “junk” bonds). High-yield securities are debt securities that are rated BB/Ba or lower by an independent rating agency, or are unrated but determined by Lord, Abbett & Co. LLC (“Lord Abbett”) to be of comparable quality. The Fund’s investments consist of the following types of securities and other financial instruments: · U.S. high-yield securities; · U.S. investment grade fixed income securities; · convertible securities; · foreign (including emerging market) securities; · mortgage-backed, mortgage-related, and other asset-backed securities; · government securities, including U.S. Government securities, municipal securities, and non-U.S. sovereign government securities; · loans, including bridge loans, novations, assignments and participations; · structured securities and other hybrid instruments, including collateralized loan obligations (“CLOs”); · inflation-linked instruments; and · equity securities. Under normal conditions, the Fund allocates its assets principally among fixed income securities in the following four asset categories: U.S. high yield securities; U.S. investment grade fixed income securities; convertible securities; and foreign (including emerging market) securities. However, the Fund may invest substantially all of its assets in any one of these categories at any time, provided that (i) at least 20% of the Fund’s net assets are invested in any combination of investment grade debt securities, U.S. Government securities, and cash equivalents, and (ii) the Fund’s investments in foreign securities, which are securities of non-U.S. issuers that are denominated in non-U.S. currencies, do not exceed 20% of its net assets. The Fund may invest up to 20% of its net assets in equity securities, including common stocks, preferred stocks, convertible preferred stocks, and similar instruments. The Fund may invest up to 15% of its net assets in floating or adjustable rate loans, including bridge loans, novations, assignments, and participations. The Fund may use derivatives to hedge against risk or to gain investment exposure. Currently, the Fund expects to invest in derivatives consisting principally of futures, forwards, options, and swaps. The Fund may use derivatives to seek to enhance returns, to attempt to hedge some of its investment risk, to manage portfolio duration, as a substitute for holding the underlying asset on which the derivative instrument is based, or for cash management purposes. For example, the Fund may invest in or sell short U.S. Treasury futures, securities index futures, other futures, and/or currency forwards to adjust the Fund’s exposure to the direction of interest rates, or for other portfolio management reasons. The portfolio management team selects securities using a bottom-up analysis of an issuer’s management quality, credit risk, and relative market position, and industry dynamics, as well as an evaluation of conditions within the broader economy. The portfolio management team attempts to reduce risk through portfolio diversification, credit analysis, and attention to current developments and trends in interest rates and economic conditions. The Fund may sell a security when the Fund believes the security is less likely to benefit from the current market and economic environment, or shows signs of deteriorating fundamentals, among other reasons. The Fund may deviate from the investment strategy described above for temporary defensive purposes. The Fund may miss certain investment opportunities if defensive strategies are used and thus may not achieve its investment objective.
Developing Growth Portfolio
Prospectus [Line Items]
Strategy [Heading]	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	The Fund invests in equity securities of companies that the portfolio management team believes demonstrate above-average, long-term growth potential. The portfolio management team seeks to identify companies that it believes are strongly positioned in the developing growth phase, which it defines as the period of swift development after a company’s start-up phase when growth is expected to occur at a rate generally not equaled by established companies in their mature years. Under normal conditions, the Fund invests at least 65% of its net assets in equity securities of small companies. A small company is defined as a company having a market capitalization at the time of purchase that falls within the market capitalization range of companies in the Russell 2000^® Index. Equity securities in which the Fund may invest include common stocks, preferred stocks, equity interests in trusts (including real estate investment trusts (“REITs”) and privately offered trusts), partnerships, joint ventures, limited liability companies and vehicles with similar legal structures, other instruments convertible or exercisable into the foregoing, and other investments with similar economic characteristics. The Fund may invest up to 20% of its net assets in securities of foreign companies, including emerging market companies, American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”), and other similar depositary receipts. In addition to ADRs, the Fund generally defines foreign companies as those whose securities are traded primarily on non-U.S. securities exchanges. The Fund may engage in active and frequent trading of its portfolio securities. The Fund may sell a security when the Fund believes the security is less likely to benefit from the current market and economic environment, or shows signs of deteriorating fundamentals, among other reasons. The Fund may deviate from the investment strategy described above for temporary defensive purposes. The Fund may miss certain investment opportunities if defensive strategies are used and thus may not achieve its investment objective.
Dividend Growth Portfolio

Strategy [Heading]	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	The Fund invests in equity securities of large and mid-sized companies that the Fund’s portfolio management team believes have potential for long-term total return and consistent increases in their dividends over time resulting from their earnings growth. In particular, the Fund focuses on large and mid-sized companies that have a ten-year history of dividend issuance and growth, which represents a narrow investable universe. The Fund may invest in companies of any size, but expects to invest in companies having a market capitalization at the time of purchase of at least $500 million. Equity securities in which the Fund may invest include common stocks, preferred stocks, equity interests in trusts (including real estate investment trusts (“REITs”) and privately offered trusts), partnerships, joint ventures, limited liability companies and vehicles with similar legal structures, other instruments convertible or exercisable into the foregoing, and other investments with similar economic characteristics. The Fund may invest up to 20% of its net assets in securities of foreign companies, including emerging market companies, American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”), and other similar depositary receipts.

Short Duration Income Portfolio
Prospectus [Line Items]
Strategy [Heading]	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	The Fund invests in various types of short duration debt (or fixed income) securities. Under normal conditions, the Fund pursues its investment objective by investing at least 65% of its net assets in investment grade debt securities of various types. Such investments include: · corporate debt securities of U.S. issuers; · corporate debt securities of non-U.S. (including emerging market) issuers that are denominated in U.S. dollars; · mortgage-backed, mortgage-related, and other asset-backed securities, including privately issued mortgage-related securities and commercial mortgage-backed securities (“CMBS”); · securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities; and · inflation-linked investments. The Fund may invest in Treasury Inflation Protected Securities (“TIPS”), which are U.S. Government bonds whose principal automatically is adjusted for inflation as measured by the Consumer Price Index for All Urban Consumers (“CPI-U”), and other inflation-indexed securities issued by the U.S. Department of Treasury. The Fund may invest up to 35% of its net assets in any one or a combination of the following types of fixed income securities and other instruments: · high-yield debt securities (commonly referred to as “lower-rated” or “junk” bonds); · debt securities of non-U.S. (including emerging market) issuers that are denominated in foreign currencies; · loans, including bridge loans, novations, assignments, and participations; · convertible securities, including convertible bonds and preferred stocks; and · structured securities and other hybrid instruments, including collateralized loan obligations (“CLOs”). The Fund will not invest more than 25% of its total assets in any industry (excluding securities of the U.S. Government, its agencies and instrumentalities); however, the Fund does not consider mortgage-related securities, including CMBS and other privately issued mortgage-related securities, as representing interests in any particular industry or group of industries. The Fund may invest substantially in CMBS, including lower-rated CMBS. The Fund seeks to manage interest rate risk through its management of the average duration of the securities it holds in its portfolio. Under normal conditions, the Fund will maintain its average dollar-weighted duration range between one and three years. The duration of a security takes into account the pattern of all expected payments of interest and principal on the security over time, including how these payments are affected by changes in interest rates. The Fund may use derivatives to hedge against risk or to gain investment exposure. Currently, the Fund expects to invest in derivatives consisting principally of futures, forwards, options, and swaps. The Fund may use derivatives to seek to enhance returns, to attempt to hedge some of its investment risk, to manage portfolio duration, as a substitute for holding the underlying asset on which the derivative instrument is based, or for cash management purposes. For example, the Fund may invest in or sell short U.S. Treasury futures, securities index futures, other futures, and/or currency forwards to adjust the Fund’s exposure to the direction of interest rates, or for other portfolio management reasons. The portfolio management team buys and sells securities using a relative value-oriented investment process, meaning the portfolio management team generally seeks more investment exposure to securities believed to be undervalued and less investment exposure to securities believed to be overvalued. The portfolio management team combines top-down and bottom-up analysis to construct its portfolio, using a blend of quantitative and fundamental research. As part of its top-down analysis, the portfolio management team evaluates global economic conditions, including monetary, fiscal, and regulatory policy, as well as the political and geopolitical environment, in order to identify and assess opportunities and risks across different segments of the fixed income market. The portfolio management team employs bottom-up analysis to identify and select securities for investment by the Fund based on in-depth company, industry, and market research and analysis. The portfolio management team may actively rotate sector exposure based on its assessment of relative value. The Fund may engage in active and frequent trading of its portfolio securities. The Fund may sell a security when the Fund believes the security is less likely to benefit from the current market and economic environment, or shows signs of deteriorating fundamentals, among other reasons. The Fund may deviate from the investment strategy described above for temporary defensive purposes. The Fund may miss certain investment opportunities if defensive strategies are used and thus may not achieve its investment objective.

Strategy Narrative [Text Block]

Under normal conditions, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities of mid-sized companies. A mid-sized company is defined as a company having a market capitalization at the time of purchase that falls within the market capitalization range of companies in the Russell Midcap^® Index. The Fund seeks to invest in securities of companies that the portfolio management team believes are undervalued by the market and are selling at reasonable prices in relation to the portfolio management team’s assessment of their potential or intrinsic value.

Strategy Narrative [Text Block]

The Fund invests in various types of short duration debt (or fixed income) securities. Under normal conditions, the Fund pursues its investment objective by investing at least 65% of its net assets in investment grade debt securities of various types. Such investments include:

· corporate debt securities of U.S. issuers;

· corporate debt securities of non-U.S. (including emerging market) issuers that are denominated in U.S. dollars;

· mortgage-backed, mortgage-related, and other asset-backed securities, including privately issued mortgage-related securities and commercial mortgage-backed securities (“CMBS”);

· securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities; and

· inflation-linked investments.

The Fund may invest in Treasury Inflation Protected Securities (“TIPS”), which are U.S. Government bonds whose principal automatically is adjusted for inflation as measured by the Consumer Price Index for All Urban Consumers (“CPI-U”), and other inflation-indexed securities issued by the U.S. Department of Treasury.

The Fund may invest up to 35% of its net assets in any one or a combination of the following types of fixed income securities and other instruments:

· high-yield debt securities (commonly referred to as “lower-rated” or “junk” bonds);

· debt securities of non-U.S. (including emerging market) issuers that are denominated in foreign currencies;

· loans, including bridge loans, novations, assignments, and participations;

· convertible securities, including convertible bonds and preferred stocks; and

· structured securities and other hybrid instruments, including collateralized loan obligations (“CLOs”).

The Fund will not invest more than 25% of its total assets in any industry (excluding securities of the U.S. Government, its agencies and instrumentalities); however, the Fund does not consider mortgage-related securities, including CMBS and other privately issued mortgage-related securities, as representing interests in any particular industry or group of industries. The Fund may invest substantially in CMBS, including lower-rated CMBS.

The Fund seeks to manage interest rate risk through its management of the average duration of the securities it holds in its portfolio. Under normal conditions, the Fund will maintain its average dollar-weighted duration range between one and three years. The duration of a security takes into account the pattern of all expected payments of interest and principal on the security over time, including how these payments are affected by changes in interest rates.

The Fund may use derivatives to hedge against risk or to gain investment exposure. Currently, the Fund expects to invest in derivatives consisting principally of futures, forwards, options, and swaps. The Fund may use derivatives to seek to enhance returns, to attempt to hedge some of its investment risk, to manage portfolio duration, as a substitute for holding the underlying asset on which the derivative instrument is based, or for cash management purposes. For example, the Fund may invest in or sell short U.S. Treasury futures, securities index futures, other futures, and/or currency forwards to adjust the Fund’s exposure to the direction of interest rates, or for other portfolio management reasons.

The portfolio management team buys and sells securities using a relative value-oriented investment process, meaning the portfolio management team generally seeks more investment exposure to securities believed to be undervalued and less investment exposure to securities believed to be overvalued. The portfolio management team combines top-down and bottom-up analysis to construct its portfolio, using a blend of quantitative and fundamental research. As part of its top-down analysis, the portfolio management team evaluates global economic conditions, including monetary, fiscal, and regulatory policy, as well as the political and geopolitical environment, in order to identify and assess opportunities and risks across different segments of the fixed income market. The portfolio management team employs bottom-up analysis to identify and select securities for investment by the Fund based on in-depth company, industry, and market research and analysis. The portfolio management team may actively rotate sector exposure based on its assessment of relative value. The Fund may engage in active and frequent trading of its portfolio securities.

The Fund may sell a security when the Fund believes the security is less likely to benefit from the current market and economic environment, or shows signs of deteriorating fundamentals, among other reasons. The Fund may deviate from the investment strategy described above for temporary defensive purposes. The Fund

may miss certain investment opportunities if defensive strategies are used and thus may not achieve its investment objective.
