In short

GTOC No data

IUSB Most core bond funds stop at investment grade. IUSB keeps going, folding high-yield USD debt into the same wrapper across roughly 18,000 bonds, for 0.06% a year.

Stated mandate

GTOC No data

IUSB The Fund seeks to track an index of U.S.-dollar-denominated bonds spanning investment-grade and high-yield sectors.

Why people hold it

GTOC No data

IUSB 0.06% a year, a fraction of what the typical broad bond fund in its category charges, and iShares has run it since 2014.
Roughly 18,000 bonds spanning investment-grade and high-yield sectors, so one ticker covers ground a plain Agg tracker leaves on the table.ishares.com
Tracks its index closely, trades heavily, and sits on a multi-billion-dollar asset base. Income is paid monthly.
Among the strongest implementations in a crowded field of nearly 200 core bond funds.

Worth knowing

GTOC No data

IUSB That high-yield sleeve is the trade-off: more credit risk than an investment-grade-only fund, and more movement when spreads widen.
BND, SPAB and SCHZ charge 0.03%, half IUSB's fee, but they stay inside investment grade.
Payouts land monthly, but the amount floats with the coupons underneath. Nothing about the income stream is fixed.
