Total Return Fund (LTRAX) - Class A

Important Information
Maximum Offering Price (MOP) - Returns with sales charges reflect applicable fees and expenses and include all distributions reinvested.
Net Asset Value (NAV) - Returns shown at net asset value 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.
Instances of high double-digit returns were achieved primarily during favorable market conditions and may not be sustainable over time.

Class A- Except as noted below, returns with sales charges reflect a maximum sales charge of 5.75% for equity and strategic allocation funds, 4.75% for Lord Abbett Bond Debenture Fund, and 2.25% for all tax-free income funds and taxable fixed income funds (except for Lord Abbett Bond Debenture Fund). There are also ongoing 12b-1 service fees (and, in certain cases, distribution fees).

Class A Shares purchased subject to a front-end sales charge have no contingent deferred sales charge (CDSC). However, certain purchases of Class A shares made without a front-end sales charge may be subject to a CDSC of 1% if the shares are redeemed before the first day of the month in which the one year anniversary of the purchase falls. The CDSC is not reflected in the performance with maximum sales charge.

A Note about Risk: Investors should realize that the Fund has the ability to invest up to 20 percent of its total assets in high-yield securities, sometimes called junk bonds. The risks of high-yield securities include, but are not limited to, price volatility and the possibility of default in the timely payment of interest and principal. In addition, the Fund has the option to invest up to 20 percent of its assets in foreign securities. Foreign securities markets may not be subject to the same degree of regulation as the U.S. markets and may be more volatile and less liquid than the major U.S. markets. Foreign investments are subject to currency exposure. These risks can be greater in the case of emerging country securities. There can be no assurance that the Fund will meet its investment objective. The value of an investment in the Fund will change as interest rates fluctuate in response to market movements. When interest rates rise, the prices of debt securities are likely to decline, and when interest rates fall, the prices of debt securities tend to rise. These factors can affect Fund performance.

The Barclays U.S. Aggregate Bond Index is an unmanaged index composed of securities from the Barclays Government/Corporate Bond Index, Mortgage-Backed Securities Index and the Asset-Backed Securities Index. Total return comprises price appreciation/depreciation and income as a percentage of the original investment. Indexes are rebalanced monthly by market capitalization.

Unless otherwise specified, indexes reflect total return, 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 Rating^TM is derived from a weighted average of the performance figures associated with a fund's three-, five-, and 10-year (as applicable) Morningstar Rating^TM 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 Rating^TM 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.

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.
