As filed, collateral included
6.1% collateralIBDS's filing lists 661 positions including 6.1% of net assets in securities-lending cash collateral. Counted as filed the fund reads 166.1 effective holdings with a top ten of 12.67%; on its own investments — the figure above — it reads 427.5 with a top ten of 7.11%. 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.

The filing reports no cash collateral position against this loan. Collateral taken in a form the fund does not hold as a position does not appear in N-PORT, so this is silence rather than absence.
