Calibrated Dividend Growth Fund (LAMAX) - 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.

Effective September 27, 2012, the Lord Abbett Capital Structure Fund changed its name to Lord Abbett Calibrated Dividend Growth Fund, and the Fund transitioned its investment approach from investing in a mix of equity and fixed income securities to a domestic dividend oriented equity strategy. Therefore, the performance of the Fund for periods prior to September 27, 2012 is not representative of the Fund's current investment strategy. The change in investment approach may affect the Fund's performance.

A Note About Risk: The Fund invests primarily in equity securities of large and mid-sized companies, which may experience significant volatility at times and may fall sharply in response to general economic conditions and to changes in the prospects of particular companies and/or sectors in the economy. Larger companies as compared to smaller successful companies may be less able to respond quickly to certain market developments and may have slower rates of growth. Securities of mid-sized companies generally involve greater risks than investments in larger companies. Mid-sized company securities tend to be more volatile and less liquid than equity securities of larger companies. If the Fund's fundamental research and quantitative analysis fail to produce the intended result, the Fund may suffer losses or underperform its benchmark or other funds with the same investment objective or similar strategies, even in a rising market. Dividend paying securities may become less available for purchase, limiting the Fund's ability to produce current income and increasing the volatility of Fund's returns. In addition, a company's dividend payments may vary over time, and there is no guarantee that a company will pay a dividend at all. These factors can affect Fund performance. The Fund changed its investment strategy on 9/27/2012, and, therefore, the fund performance history under the new strategy at this time is very limited. The Fund's performance achieved during its initial period of investment operation may not be replicated over longer periods and may not be indicative of how the Fund will perform in the future.

The S&P 500® Index is widely regarded as the standard for measuring large-cap U.S. stock market performance and includes a representative sample of leading companies in leading industries.

The S&P 900^® 10-Year Dividend Growth Index, which is a subset of the S&P 900 Index, consists of large and mid-sized companies that have a substantial history of dividend issuance and growth, and that meet certain other criteria. The Dividend Growth Index represents a considerably narrower investable universe than the S&P 900 Index because of the stringent criteria for inclusion in the Dividend Growth Index. Characteristics and historical performance of the S&P 900^® 10-Year Dividend Growth Index are provided for information purposes only. Portfolio holdings and characteristics of the Fund will differ from those of the index, and such differences may be material.

Under a contract with Lord Abbett, S&P administers, maintains, and calculates the Index. S&P and its affiliates shall have no liability for any errors or omissions in calculating the Index.

Expense Ratio Details
The net expense ratio takes into account a contractual management fee waiver/expense reimbursement agreement that currently is scheduled to remain in place through 03/31/2014. For periods when gross expenses exceeded the cap, the Fund benefited by not bearing certain expenses. Without such cap, performance would have been lower.
