Freedom to Invest Globally in Any Income-Producing Security

Thornburg Strategic Income Fund is a broadly flexible income-oriented portfolio with a wide investment mandate and the freedom to invest in any income-producing security, anywhere in the world. We aim to provide a strong, consistent income stream that preserves investors’ purchasing power, while not exposing them to undue risk.

Working Photo“With this fund, we strive for competitive return and balanced risks through active research in the global market for income-producing products, and by comparing the relative risks and rewards across many asset classes and subclasses. True to Thornburg’s mantra, this portfolio is designed to go where the value is.”

— Jason Brady

Beyond a Single Asset Class

Investors often associate higher income with the high-yield asset class, but moving down the credit-quality spectrum within one asset class doesn’t always provide it, and can expose investors to significant risks.

We seek the high and sustainable income that is associated with the high-yield asset class, without many of the risks and strictures inherent in it.

A Broad Purview

We invest flexibly and in a wide variety of asset classes: mortgages, Treasuries, corporates, preferred stocks, convertibles, foreign sovereign debt—anything in which the risk/reward tradeoff appears compelling.

Unlike a typical high-yield fund, we are not forced by a restrictive mandate to take credit risk in every corner of the portfolio.

Harnessing Thornburg’s Open, Continuous Investment Process

Since the fund has such a broad scope and can invest in any income-producing security anywhere in the world, the way the team works together is the most important key to success. As a group, we look at everything out there. With so many market niches to examine, we are constantly engaged in comparing one compelling opportunity with another.

Our job with this portfolio is, in a sense, comparing apples to oranges. By sitting side-by-side and constantly exchanging information, we are able to make sure that all opportunities available are discussed, compared, contrasted, and ultimately, for most of them, discarded.

Individual, Bottom-Up Asset and Credit Work

Hard, rigorous credit work on an individual, security-by-security basis underpins the selection process. The portfolio is built from the bottom up and performance is driven by individual asset behavior, not by monolithic moves in macroeconomic variables.

No Use of Leverage

We don’t use leverage in Strategic Income Fund, and we don’t use derivatives to mask leverage.

Reasonable Pursuit of Reasonable Objectives

We don’t attempt to knock the ball out of the park every year, or even in any given year, but strive to balance the pursuit of attractive income with the assumption of a moderately higher level of risk.

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

Investments carry risks, including possible loss of principal. Portfolios investing in bonds have the same interest rate, inflation, and credit risks that are associated with the underlying bonds. The value of bonds will fluctuate relative to changes in interest rates, decreasing when interest rates rise. This effect is more pronounced for longer-term bonds. Unlike bonds, bond funds have ongoing fees and expenses. Investments in lower rated and unrated bonds may be more sensitive to default, downgrades, and market volatility; these investments may also be less liquid than higher rated bonds. Investments in derivatives are subject to the risks associated with the securities or other assets underlying the pool of securities, including illiquidity and difficulty in valuation. Investments in equity securities are subject to additional risks, such as greater market fluctuations. Additional risks may be associated with investments outside the United States, especially in emerging markets, including currency fluctuations, illiquidity, volatility, and political and economic risks. Investments in the Fund are not FDIC insured, nor are they bank deposits or guaranteed by a bank or any other entity.

Credit quality ratings for Thornburg’s global fixed income portfolios used ratings from Moody’s Investors Service. Where Moody’s ratings are not available, we have used S&P Global Ratings. Where neither rating is available, we have used ratings from other nationally recognized statistical rating organizations (NRSROs).

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.

The performance of any index is not indicative of the performance of any particular investment. Unless otherwise noted, index returns reflect the reinvestment of income dividends and capital gains, if any, but do not reflect fees, brokerage commissions or other expenses of investing. Investors may not make direct investments into any index.

Thornburg Strategic Income Fund’s Blended Index is composed of 80% Bloomberg Barclays U.S. Aggregate Bond Index and 20% MSCI World Index, rebalanced monthly.
