|---|---|---|
| BARCLAYS BANK PLC | $30,366 | 100.0% |
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.

Since the previous filing
2026-03-31 → 2026-06-3039 positions became 40: 2 added (0.4% of the fund at the later date), 1 dropped (0.3% at the earlier date). Half the sum of all weight changes, a turnover proxy: 2.5%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

Asset categories and pricing
as of 2026-06-3099.74% equity, 0.26% short-term investment as filed; 100.0% carried at a quoted market price (fair-value level 1). Categories and levels are the filer's; what a low level-1 share does and does not mean is in the measure's page.
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 $875M. Notional of an interest-rate or currency swap is not equity exposure.
