Who borrows IFRA'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, $38m was out to 13 borrowers, 0.81% of net assets. The largest, JP MORGAN SECURITIES LLC, held 30.6% of it.

BorrowerOn loanShare of the loan
JP MORGAN SECURITIES LLC $12m 30.6%
TD SECURITIES (USA), LLC $7m 18.4%
BNP PARIBAS PRIME BROKERAGE INTERNATIONAL LIMITED $7m 17.4%
CITIGROUP GLOBAL MARKETS INC. $6m 16.7%
HSBC BANK PLC $3m 7.0%

Cash collateral reported against the loan: 0.85% of net assets, 104.4% 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 IFRA has filed, with each borrower: IFRA.json · all funds.

Since the previous filing

2026-03-31 → 2026-06-30

166 positions became 164: 3 added (0.1% of the fund at the later date), 5 dropped (0.1% at the earlier date). Half the sum of all weight changes, a turnover proxy: 4.5%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of IFRA compared this way, as a feed: changes.xml · all funds: filings received.

99.11% equity, 0.89% 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 $4.62B. Notional of an interest-rate or currency swap is not equity exposure.
