Returns the fund reported

Who borrows OIH's shares
2026-06-30The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-06-30, $234m was out to 8 borrowers, 11.77% of net assets. The largest, BARCLAYS BANK PLC, held 76.2% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| BARCLAYS BANK PLC | $179m | 76.2% |
| BNP PARIBAS PRIME BROKERAGE INTERNATIONAL LIMITED | $44m | 18.9% |
| HSBC BANK PLC | $5m | 2.3% |
| UBS AG | $3m | 1.4% |
| BofA Securities, Inc. | $1m | 0.6% |
Cash collateral reported against the loan: 0.01% of net assets, 0.1% 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 OIH has filed, with each borrower: OIH.json · all funds.
Since the previous filing
2026-03-31 → 2026-06-3025 positions became 25: 0 added (0.0% of the fund at the later date), 0 dropped (0.0% at the earlier date). Half the sum of all weight changes, a turnover proxy: 5.3%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of OIH compared this way, as a feed: changes.xml · all funds: filings received.
