About TBIWX

Nuveen Bond Index Fund Class W is an open-end mutual fund designed to deliver broad exposure to the U.S. investment-grade bond market. The fund's primary objective is to achieve a favorable long-term total return, mainly through income, by closely tracking the Bloomberg U.S. Aggregate Bond Index using a sampling approach. This means the fund holds a diverse portfolio of investment-grade bonds in proportions that mirror the risk and return characteristics of its benchmark, without necessarily investing in every constituent security. The fund invests at least 80% of its assets in bonds that are part of the index, primarily including U.S. Treasury and government agency issues, mortgage-backed securities, and high-quality corporate bonds. As such, it plays a core role for investors seeking fixed income market exposure with moderate credit quality and interest rate sensitivity. The fund features a notably low expense ratio, a hallmark of its cost-efficient index tracking strategy, and pays monthly dividends to shareholders, further enhancing its suitability for income-focused portfolios. Nuveen Bond Index Fund Class W is widely used as a foundational building block in diversified portfolios, retirement accounts, and as a component in multi-asset investment strategies, underscoring its significance in the broader financial market.
