The Laddered Bond Portfolio

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

Thornburg Intermediate Municipal Fund

 

Overview

Investment Philosophy
Thornburg Intermediate Municipal Fund is a laddered portfolio of municipal bonds from throughout the U.S. with an average maturity of ten years or less. Investments with shorter average maturities, such as the Thornburg Intermediate Municipal Fund, are less exposed to interest rate risk than investments with longer average maturities.

Fund Objective
Obtain as high a level of current income exempt from federal individual income tax as is consistent, in the view of the Fund's investment advisor, with preservation of capital. A secondary objective is to reduce expected changes in its share price compared to long-term bond portfolios.

There is no guarantee that the Fund will meet its investment objectives. A portion of the Fund's dividends could be subject to the federal Alternative Minimum Tax.

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. The strategy is a good compromise for managing different types of risk. Read More...

Important Information

Investments in the Funds carry risks including possible loss of principal. 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 value of a bond will fluctuate relative to changes in interest rates; as interest rates rise, the overall price of bonds fall. Unlike bonds, bond funds have ongoing fees and expenses. Investments in the funds are not deposits or obligations of, or guaranteed or endorsed by, any bank, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any governmental agency.

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

Carefully consider the Fund’s investment objectives, risks, sales charges, and expenses; these are found in the prospectus, which is available from your financial advisor or from our download library. Read it carefully before you invest or send money.

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.
