Thornburg Investment Income Builder Fund's Blended Index is composed of 25% Bloomberg U.S. Aggregate Total Return Value USD and 75% MSCI World Net Total Return USD Index, rebalanced monthly.

Performance data shown represents past performance and is no guarantee of future results. Investment return and principal value will fluctuate so shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than quoted.

The maximum sales charge for the equity funds' A shares is 4.50%. C shares include a 1% contingent deferred sales charge (CDSC) for the first year only. There is no up-front sales charge for class I or R shares.

Morningstar quartile ranking for Global Moderately Aggressive Allocation category is based on total returns before sales charges.

Prior to inception of I and R share classes, performance is hypothetical and was calculated from actual returns of an earlier share class adjusted for the expenses of the newer share class.

Share class inception dates: A shares, 24 Dec 2002; C shares, 24 Dec 2002; I shares, 3 Nov 2003; R3 shares, 1 Feb 2005; R4 shares, 1 Feb 2008; R5 shares, 1 Feb 2007; R6 shares, 10 Apr 2017.

Sector, Industry, and Market Capitalization are based on the portfolio's equity holdings. Credit Quality and Maturity are based on the portfolio’s fixed income holdings. Geography and Asset Class are based on the full portfolio.

Credit quality ratings use the highest rating available from either S&P Global Ratings or Moody's Investors Service. Unrated securities are evaluated by the firm using available data and their own analysis that may be similar to that of a nationally recognized rating agency; however, such determination is not equivalent to a national agency credit rating. "NR" = Not Rated.

Weights are percentages of the total portfolio unless otherwise noted.

May not add up to 100% due to rounding.

Cash and Equivalents includes cash, short-term securities, other assets less liabilities, accruals, derivatives and forwards. It may also include investments in money market or similar funds managed by Thornburg that are not offered to the public.

Holdings with the Geography breakdown are classified by country of risk as determined by MSCI and Bloomberg.

Important Information

This communication is not authorized for distribution to prospective investors in the Fund unless preceded or accompanied by an effective prospectus.

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.

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

Neither the payment of, or increase in, dividends is 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 S&P Global 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.

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

To determine a fund's Morningstar Rating™, funds and other managed products with at least a three-year history are ranked in their categories by their Morningstar Risk-Adjusted Return scores. The top 10% receive 5 stars; the next 22.5%, 4 stars; the middle 35%, 3 stars; the next 22.5%, 2 stars; and the bottom 10% receive 1 star. The Risk-Adjusted Return accounts for variation in a managed product's monthly excess performance (excluding sales charges), placing more emphasis on downward variations and rewarding consistent performance. Other share classes may have different performance characteristics.
