As filed, collateral included
8.34% collateralSLY's filing lists 603 positions including 8.34% of net assets in securities-lending cash collateral. Counted as filed the fund reads 106.9 effective holdings with a top ten of 13.41%; on its own investments — the figure above — it reads 416 with a top ten of 5.55%. 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.

Cash collateral reported against the loan: 8.34% of net assets, 83% of the amount lent. That is a floor on the collateral, not the whole of it — collateral the fund does not hold as a position is not in this filing, so a figure under 100% is not evidence of under-collateralisation. How that figure behaves across all funds. Every quarter SLY has filed, with each borrower: SLY.json · all funds.
