Strategy. Under normal conditions, the Fund pursues its investment objective by investing at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in a diversified portfolio of convertible securities issued by U.S. and foreign companies. Convertible securities may include corporate bonds, debentures, notes, preferred stocks, and any other securities that can be exchanged for equity securities or provide an opportunity for equity participation. For purposes of this 80% policy, the Fund also may gain exposure to convertible securities through derivatives or other synthetic means.

Convertible securities may include corporate bonds, debentures, notes, preferred stocks, and any other securities that can be exchanged for equity securities or provide an opportunity for equity participation. For purposes of this 80% policy, the Fund also may gain exposure to convertible securities through derivatives or other synthetic means. The Fund may invest in both investment grade convertible securities and lower-rated (commonly referred to as high-yield or junk) convertible securities or, if unrated, determined by Lord Abbett to be of comparable quality. The Fund may invest in companies of all sizes and may from time to time invest a significant amount of its assets in securities of small and mid-sized companies and below investment grade securities. The Fund may invest up to 20% of its net assets in non-convertible debt or equity securities. In addition, the Fund may invest up to 20% of its net assets in foreign securities. The Fund defines foreign securities as securities of non-U.S. issuers that are denominated in non-U.S. currencies. The Fund will not invest more than 25% of its total assets in any industry; however, this limitation does not apply to mortgage-backed securities, privately issued mortgage-related securities, or securities issued by the U.S. Government, its agencies and instrumentalities. 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. Specifically, the Fund expects to employ a variety of options strategies for the Fund, including purchasing and selling put and call options, as well as utilizing spreads and other option combinations. In spread transactions, the Fund buys and writes a put or buys and writes a call on the same underlying instrument with the options having different expiration dates. The Fund may also take advantage of the pricing inefficiencies of an embedded option through the purchase of a convertible bond. Such convertible arbitrage strategies seek to take advantage of the pricing inefficiencies of the embedded option in a convertible bond. Convertible arbitrage involves purchasing a portfolio of convertible securities, generally convertible bonds, and hedging a portion of the equity risk by selling short the underlying common stock. 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 Funds exposure to the direction of interest rates, or for other portfolio management reasons. The portfolio management team uses fundamental, bottom-up analysis to identify convertible securities that it believes are undervalued and that potentially may increase total return and reduce downside risk. The portfolio management team will work toward reducing risk through portfolio diversification, credit analysis, assessment of risk/return potential, and attention to current developments and trends in interest rates and economic conditions. The Fund engages 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. Show less
