Who borrows BBAG's shares
2025-08-31The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2025-08-31, $2m was out to 6 borrowers, 0.13% of net assets. The largest, BARCLAYS BANK PLC, held 47% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| BARCLAYS BANK PLC | $781,262 | 47.0% |
| NOMURA SECURITIES INTERNATIONAL INC. | $440,743 | 26.5% |

Cash collateral reported against the loan: 0.13% of net assets, 99.7% 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 BBAG has filed, with each borrower: BBAG.json · all funds.

Half the sum of all weight changes, a turnover proxy: 10.2%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.
