As filed, collateral included
9.82% collateralIBDZ's filing lists 376 positions including 9.82% of net assets in securities-lending cash collateral. Counted as filed the fund reads 76.5 effective holdings with a top ten of 17.39%; on its own investments — the figure above — it reads 283.2 with a top ten of 8.35%. The collateral is matched by a liability and is not a holding the fund chose; since 2026-09-18 every figure on this site sets it aside (methodology). Both numbers are in the data.
