The Laddered Bond Portfolio:
A Strategy for Managing Risk and Capturing Compelling Market Returns

Thornburg Limited Term U.S. Government Fund

 

Overview

Investment Philosophy
Thornburg Limited Term U.S. Government Fund is a laddered portfolio of short/intermediate obligations issued by the U.S. Government, its agencies or instrumentalities, with an average maturity of five years or less. 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.

Laddered Portfolio Strategy
Laddering involves building a portfolio of bonds with staggered maturities so that a portion of the portfolio will mature each year. To maintain the ladder, cash from maturing bonds is typically invested in bonds with longer maturities at the far end of the ladder. Read More...
