As part of iShares Corporate Term Bond suite, IBDT behaves more like a bond than a typical bond fund. The fund provides bullet maturity--in this case for December 2028--instead 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), IBDT will unwind and return all capital to investors. This structure permits IBDT 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.
