As part of iShares Corporate Term Bond suite, IBDU behaves more like a bond than a typical bond fund. The fund provides bullet maturityin this case for December 2029instead of perpetual exposure to a maturity pocket of the US corporate investment-grade bond market. As the fund matures, its maturity, duration, and YTM will continue to decline. On its target date (tentatively, December 15, 2029), IBDU will unwind and return all capital to investors. This structure permits IBDU to be used as a building block for a bond ladder. In all, the fund provides a viable means to access a diverse pool of US investment-grade bonds while mimicking the life cycle of an individual bond.
