Who borrows EUSB's shares
2026-05-31The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-05-31, $5m was out to 15 borrowers, 0.65% of net assets. The largest, BARCLAYS BANK PLC, held 22.1% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| BARCLAYS BANK PLC | $1m | 22.1% |

Cash collateral reported against the loan: 0.67% of net assets, 103.8% 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 EUSB has filed, with each borrower: EUSB.json · all funds.
