Who borrows EUSB's shares

2026-05-31

The 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.

BorrowerOn loanShare of the loan
BARCLAYS BANK PLC $1m 22.1%
JP MORGAN SECURITIES LLC $769,826 16.9%
National Bank Financial Inc. $510,230 11.2%
BNP PARIBAS PRIME BROKERAGE INTERNATIONAL LIMITED $450,325 9.9%
GOLDMAN SACHS & CO. $317,465 7.0%

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.

Since the previous filing

2026-02-28 → 2026-05-31

4,206 positions became 4,233: 333 added (7.1% of the fund at the later date), 306 dropped (7.1% at the earlier date). Half the sum of all weight changes, a turnover proxy: 9.6%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of EUSB compared this way, as a feed: changes.xml · all funds: filings received.
