The 30-Day Standardized Yield represents net investment income earned by a fund over a 30-day period. It is expressed as an annual percentage rate using a method of calculation adopted by the Securities and Exchange Commission (SEC). Yields for other share classes will vary.

The 30-day Standardized Subsidized yields reflect fee waivers in effect. Without such fee waivers, yields would be reduced.  

The 30-day Standardized Unsubsidized yield does not reflect fee waivers.

Average Yield to Worst is a measure of the lowest possible yield that can be received on a bond with an early retirement provision.
 

Distribution Yield is the calculation of cash flow for an investment vehicle, to calculate the distribution yield, the most recent distribution is multiplied by 12 to get an annualized total, which is then divided by the NAV.

IMPORTANT INFORMATION

A Note about Risk: 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 likley to decline, and when interest rates fall, the prices of debt securities tend to rise. High-yielding non-investment grade bonds involve higher risk than investment grade bonds. Adverse conditions may affect the issuer's ability to pay interest and principal on those securities. A portion of the income derived from the Fund's portfolio may be subject to the alternative minimum tax. Any capital gains realized may be subject to taxation. Federal, state, and local taxes may apply. There is a risk that a bond issued as tax-exempt may be reclassified by the IRS as taxable, creating taxable rather than tax-exempt income. In addition, the Fund is subject to other types of risks, such as call, credit, liquidity, interest rate, and general market risks. The Fund may invest in bonds of issuers in Puerto Rico and other U.S. territories, comonwealths, and possessions, and may be affected by local, state, and regional factors. These may include, for example, economic or political developments, erosion of the tax base, and the possibility of credit problems. Stockholders should consult with their tax advisor for more specific information on taxation.

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.
