About TIBAX

Thornburg Investment Income Builder Fund Class A is an actively managed mutual fund specializing in global, multi-asset allocation. Its primary objective is to generate a consistent stream of income that exceeds the average yield on U.S. equities, with long-term capital appreciation as a secondary goal. To achieve this, the fund invests across a diversified portfolio of income-producing securities—mainly common stocks and bonds—and typically allocates at least 80% of assets to such instruments, with over half in equities. The fund is notable for its worldwide reach, holding securities from various sectors including communication services, energy, technology, financial services, and utilities. Managed by Thornburg Investment Management, it features quarterly dividend distributions and maintains a high dividend yield relative to peers. The fund’s large number of holdings and moderate turnover provide broad exposure while its focus on dividend growth supports both income needs and principal growth. As a long-standing participant in the world allocation category since its inception in 2002, it serves investors seeking reliable income and growth through diversified global investments.
