As filed, collateral included
1.58% collateralDFSB's filing lists 741 positions including 1.58% of net assets in securities-lending cash collateral. Counted as filed the fund reads 190 effective holdings with a top ten of 14.82%; on its own investments — the figure above — it reads 228.5 with a top ten of 13.29%. 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.
