Why people hold it

• IBTI Charges 0.07% a year against a 0.10% median for target-maturity bond funds. On a Treasury portfolio, where the yield is knowable, the fee comes straight off the top.
• Every bond in it matures in 2028, so the portfolio winds down toward a set date rather than rolling on forever like a standard bond index fund.
• US Treasuries only, about 40 of them. No corporate issuer to underwrite, just one slice of the government curve.
• Pays monthly, holds over a billion in assets, and ranks among the stronger implementations in a category otherwise full of thin, niche rungs.

LFAI —No data

Worth knowing

• IBTI The defined maturity belongs to the bonds, not to your entry price. Exit before the target year and you take whatever rates have done since.
• This is one point on the yield curve, not a ladder. Covering several maturity years means owning several of these funds.
• Treasury-only means no credit spread. Corporate-bond cousins like VBCB and IBDU take on issuer risk in exchange for the extra yield.
