Lord Abbett Inflation Focused Fund Class I LIFIX Strategy

The investment seeks investment returns that exceed the rate of inflation in the U.S. economy over a full economic cycle; the secondary objective is current income. The fund uses the Consumer Price Index ("CPI") for All Urban Consumers to measure the rate of inflation in the U.S. economy. It pursues its investment objective by combining inflation-linked derivatives and inflation-indexed fixed income securities (collectively, "Inflation-Linked Investments") with a portfolio of fixed income securities. In addition, the fund may buy or sell Treasury futures or interest rate swaps to actively manage its portfolio duration.
