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. 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 small- and mid-capitalization companies may increase the risk of greater price fluctuations. 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. Investments in the Fund are not FDIC insured, nor are they bank deposits or guaranteed by a bank or any other entity.

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 Investment Income Builder Fund's Blended Index is composed of 25% Bloomberg Barclays U.S. Aggregate Bond Index and 75% MSCI World Index, rebalanced monthly.

Diversification does not assure or guarantee better performance and cannot eliminate the risk of investment losses.

Dividends are not guaranteed.

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.

Credit quality ratings for Thornburg Investment Income Builder used ratings from Moody’s Investors Service. Where Moody’s ratings are not available, we have used Standard & Poor’s ratings. Where neither rating is available, we have used ratings from other nationally recognized statistical rating organizations (NRSROs).

Class R shares are limited to retirement platforms only.

Class I shares may not be available to all investors. Minimum investments for the I share class may be higher than those for other classes.
