Who borrows IWF's shares

2026-06-30

The 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.

BorrowerOn loanShare 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 → 2026-06-30

388 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. Every filing of IWF compared this way, as a feed: changes.xml · all funds: filings received.

99.26% equity, 0.74% short-term investment as filed; 100.0% carried at a quoted market price (fair-value level 1). Categories and levels are the filer's; what a low level-1 share does and does not mean is in the measure's page.

Derivative exposure and counterparties

as of 2026-06-30

A 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.
