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: The Fund invests primarily in mid cap growth company stocks, which tend to be more volatile and can be less liquid than other types of stocks. Mid cap companies typically experience a higher risk of failure than large cap companies. These factors can affect Fund performance.

The Russell Midcap® Growth Index measures the performance of those Russell Midcap companies with higher price-to-book ratios and higher forecasted growth values. The stocks are also members of the Russell 1000 Growth index.

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.

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.

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.
