Who borrows IWF'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, $753m was out to 24 borrowers, 0.58% of net assets. The largest, BofA Securities, Inc., held 41.4% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| BofA Securities, Inc. | $311m | 41.4% |
| CITIGROUP GLOBAL MARKETS INC. | $137m | 18.3% |
| JP MORGAN SECURITIES LLC | $97m | 12.9% |
| MORGAN STANLEY & CO LLC | $63m | 8.3% |
| Wells Fargo Bank, National Association | $52m | 6.9% |
Cash collateral reported against the loan: 0.55% of net assets, 94.2% 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 IWF has filed, with each borrower: IWF.json · all funds.
Since the previous filing
2026-03-31 → 2026-06-30388 positions became 370: 98 added (9.8% of the fund at the later date), 116 dropped (3.5% at the earlier date). Half the sum of all weight changes, a turnover proxy: 27.5%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

Derivative exposure and counterparties
as of 2026-06-30A position count cannot describe a fund that uses derivatives, because a swap is filed at its unrealised gain, not its exposure. These are the notionals the fund itself reported, against net assets of $128.90B. Notional of an interest-rate or currency swap is not equity exposure.
