Who borrows AIRR'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, $2m was out to 1 borrower, 0.02% of net assets.

BorrowerOn loanShare of the loan
TD SECURITIES (USA), LLC $2m 100.0%

Cash collateral reported against the loan: 0.02% of net assets, 97.4% 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 AIRR has filed, with each borrower: AIRR.json · all funds.

Since the previous filing

2026-03-31 → 2026-06-30

53 positions became 52: 3 added (3.1% of the fund at the later date), 4 dropped (2.3% at the earlier date). Half the sum of all weight changes, a turnover proxy: 13.7%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of AIRR compared this way, as a feed: changes.xml · all funds: filings received.
