Who borrows IUSG'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, $129m was out to 16 borrowers, 0.40% of net assets. The largest, UBS AG, held 29.8% of it.

BorrowerOn loanShare of the loan
UBS AG $38m 29.8%
CITIGROUP GLOBAL MARKETS INC. $26m 20.5%
JP MORGAN SECURITIES LLC $22m 17.0%
Wells Fargo Bank, National Association $14m 10.8%
BofA Securities, Inc. $9m 7.1%

Cash collateral reported against the loan: 0.39% of net assets, 97.7% 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 IUSG has filed, with each borrower: IUSG.json · all funds.

Since the previous filing

2026-03-31 → 2026-06-30

386 positions became 392: 10 added (0.7% of the fund at the later date), 4 dropped (0.1% at the earlier date). Half the sum of all weight changes, a turnover proxy: 9.2%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of IUSG compared this way, as a feed: changes.xml · all funds: filings received.

99.52% equity, 0.48% 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 $32.22B. Notional of an interest-rate or currency swap is not equity exposure.
