Overview

Lipper Rating for PreservationInvestment Strategy
Thornburg Limited Term Income Fund is a laddered portfolio of short/intermediate investment grade obligations with an average maturity of less than five years. Investments with shorter average maturities, such as the Thornburg Limited Term Income Fund, are less exposed to interest rate risk than investments with longer average maturities.

Fund Objective
Provide as high a level of current income as is consistent, in the view of the Fund's investment advisor, with safety of capital. A secondary objective is to reduce changes in its share price compared to longer term portfolios.

There is no guarantee that the Fund will meet its investment objectives.

Laddered Portfolio Strategy
The laddered bond portfolioLaddering involves building a portfolio of bonds withstaggeredmaturities so that a portion of the portfolio will mature each year. To maintain the ladder, cash from maturing bonds is invested in bonds with longer maturities at the far end of the ladder. The strategy is a good compromise for managing different types of risk.

Lipper ratings for Total Return reflect funds’ historical total return performance relative to peers. Lipper ratings for Consistent Return reflect funds’ historical risk-adjusted returns, adjusted for volatility, relative to peers. Lipper ratings for Preservation reflect the funds’ historical loss avoidance relative to other funds within the fixed income asset class. The ratings are subject to change every month and are based on an equal-weighted average of percentile ranks for each metric over three-, five-, and ten-year periods (if applicable). The highest 20% of funds in each peer group are named Lipper Leader, or a score of 5, the next 20% receive a score of 4, the middle 20% are scored 3, the next 20% are scored 2, and the lowest 20% are scored 1. Lipper ratings are relative, rather than absolute, measures, and funds named Lipper Leaders may still experience losses periodically; those losses may be larger for equity and mixed equity funds than for fixed income funds. Lipper ratings are not intended to predict future results, and Lipper does not guarantee the accuracy of this information. More information is available at www.lipperweb.com.

A bond credit rating assesses the financial ability of a debt issuer to make timely payments of principal and interest. Ratings of AAA (the highest), AA, A, and BBB are investment-grade quality. Ratings of BB, B, CCC, CC, C and D (the lowest) are considered below investment grade, speculative grade, or junk bonds. We have used ratings from Moody’s Investors Service. Where Moody’s ratings are not available, we have used Standard & Poor’s ratings. “NR” = not rated.

Important Information

Investments in the Fund carry risks, including possible loss of principal. Bond funds have the same interest rate, inflation, and credit risks that are associated with the underlying bonds. The principal value of bonds will fluctuate relative to changes in interest rates, decreasing when interest rates rise. Unlike bonds, bond funds have ongoing fees and expenses. Funds invested in mortgage backed securities may bear additional risk. Investments in the Fund are not FDIC insured, nor are they deposits of or guaranteed by a bank or any other entity.

There is no guarantee that the Fund will meet its investment objectives.

Before investing, carefully consider the Fund’s investment goals, risks, charges, and expenses. For a prospectus containing this and other information, contact your financial advisor or visit our literature library. Read it carefully before investing.

Lipper’s large firm universe is comprised of fund families with more than $28 billion in total net assets. Only fund families with at least five bond funds were eligible. Risk-adjusted returns are calculated with dividends reinvested and without sales charges. Past performance does not guarantee future results. The individual funds may not have ranked number one in their categories.
