Overview

Lipper Rating for PreservationInvestment Strategy

Investments with shorter average maturities, such as the Thornburg Limited Term U.S. Government Fund, are less exposed to interest rate risk than investments with longer average maturities.

The Government Fund invests 80% of its assets in obligations issued or guaranteed by the United States Government, its agencies, instrumentalities or authorities. Although the share price of the fund itself is not guaranteed by the U.S. Government.

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.

Important Information

Investments in the Fund carry risks including possible loss of principal. The Fund invests a portion of the assets in Mortgage Backed Securities which are subject to pre-payment risk. This may reduce the potential for capital appreciation and may cause greater volatility in the Fund.  As with direct bond ownership, funds that invest in bonds are subject to certain risks including interest-rate risk, credit risk, and inflation risk. The principal value of bond funds will fluctuate relative to changes in interest rates; decreasing when interest rates rise. Unlike bonds, bond funds have ongoing fees and expenses 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.

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 the Preservation 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, for Preservation, 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. Preservation ratings are relative, rather than absolute, measures, and funds named Lipper Leaders for Preservation 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.
