Cash collateral reported against the loan: 0.19% of net assets, 4.7% 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 XLB has filed, with each borrower: XLB.json · all funds.
Since the previous filing
2026-03-31 → 2026-06-3028 positions became 27: 1 added (2.5% of the fund at the later date), 2 dropped (2.4% at the earlier date). Half the sum of all weight changes, a turnover proxy: 7.7%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

Derivative exposure and counterparties
as of 2026-06-30A position count cannot describe a fund that uses derivatives, because a swap is filed at its unrealised gain, not its exposure. These are the notionals the fund itself reported, against net assets of $8.17B. Notional of an interest-rate or currency swap is not equity exposure.
