Developing Growth Fund

IMPORTANT INFORMATION

A Note about Risk: The value of investments in equity securities will fluctuate in response to general economic conditions and to changes in the prospects of particular companies, including market, liquidity, currency, and political risks. Small cap company stocks tend to be more volatile and may be less liquid than other types of stocks. Small cap companies may also have more limited product lines, markets, or financial resources and typically experience a higher risk of failure than large cap companies. Investments in growth companies can be more sensitive to the company's earnings and more volatile than the stock market in general. The Fund engages in active and frequent trading of its securities, which may result in increased transaction fees, reduced investment performance, and higher taxes. These factors can adversely affect Fund performance.

Performance data quoted is historical. Past performance is not indicative of future results. Current performance may be higher or lower than the performance quoted. The investment return and principal value of an investment in the Fund will fluctuate so that shares, on any given day or when redeemed, may be worth more or less than their original cost. To obtain performance data current to the most recent quarter-end, go to quarter ending performance on our Website or call Lord Abbett at (888) 522-2388.

With Sales Charge - Returns with sales charges reflect applicable fees and expenses and include all distributions reinvested.

Without Sales Charge - Returns shown are without sales charges and have all distributions reinvested. If a sales charge had been deducted, the results would have been lower.

Returns shown at less than a year reflect aggregate total returns.

Double-Digit Returns - instances of high double-digit returns were achieved primarily during favorable market conditions and may not be sustainable over time.   

Indexes reflect total return, unless otherwise specified, with all dividends reinvested. Indexes are unmanaged, do not reflect the deduction of fees or expenses, and are not available for direct investment.

The Overall Morningstar RatingTM is derived from a weighted average of the performance figures associated with a fund's three-, five-, and 10-year (as applicable) Morningstar RatingTM metrics. © Morningstar, Inc. All rights reserved. The information contained herein (1) is proprietary to Morningstar and/or its content providers; (2) may not be copied or distributed; and (3) is not warranted to be accurate, complete or timely. Neither Morningstar nor its content providers are responsible for any damages or losses arising from any use of this information.

Morningstar proprietary ratings reflect historical risk-adjusted performance. For each fund with at least a three-year history, Morningstar calculates a Morningstar RatingTM based on a Morningstar risk-adjusted return measure that accounts for variation in a fund's monthly performance (including the effects of sales charges, loads and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. Load-waived ratings do not include any front-end sales charges (which are only available for certain defined contribution plans and certain mutual fund advisory programs) and should only be considered by investors who are not subject to sales loads. Not all funds with a load-waived rating may waive their front-end load. An investor should check with their advisor to determine if they are eligible to purchase the load-waived Class A share. The top 10% of the funds in an investment category receive 5 stars, 22.5% receive 4 stars, 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages). The Overall Morningstar rating is a weighted average of funds' three-, five-, and 10-year (as applicable) ratings. Past performance is no guarantee of future results. Morningstar Rating is for the Class A share only; other classes may have different performance characteristics.

Lipper Category Average - Peer group averages are based on universes of funds with the same investment objectives. The average return for the peer group is based on the returns of each individual fund within the group for the period shown. This average assumes reinvestment of dividends.

Fund Expense Ratio Detail: Reflects expenses for the Fund's fiscal year-end and is subject to change. Fund expenses may fluctuate with market volatility. A substantial reduction in Fund assets (since its most recently completed fiscal year), whether caused by market conditions or significant redemptions or both, will likely cause total operating expenses (as a percentage of Fund assets) to become higher than those shown.

The Fund's portfolio is actively managed and portfolio characteristics, such as individual holdings and sector weightings may change significantly over time. The portfolio data is for information only. It does not constitute a recommendation or an offer for a particular security or fund, nor should it be taken as a solicitation or recommendation to buy or sell securities or other investments.
