Who borrows IBTH's shares
2026-04-30The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-04-30, $48m was out to 1 borrower, 2.22% of net assets.
| Borrower | On loan | Share of the loan |
|---|---|---|
| GOLDMAN SACHS & CO. | $48m | 100.0% |
Cash collateral reported against the loan: 2.27% of net assets, 102.2% 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 IBTH has filed, with each borrower: IBTH.json · all funds.
Since the previous filing
2026-01-31 → 2026-04-3052 positions became 52: 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: 0.2%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of IBTH compared this way, as a feed: changes.xml · all funds: filings received.
