As part of Invesco's BulletShares investment-grade suite, BSCU behaves more like a bond than a typical bond fund. The fund provides bullet maturity, in this case, of December 2030 instead of perpetual exposure to a maturity pocket of the US corporate investment-grade market. As the fund matures, its maturity, duration and YTM will continue to decline. On its target date, BSCU will unwind and return all capital to investors. This structure permits BSCU to be used as a building block for a bond ladder.
