Who borrows AGZ's shares

2026-05-31

The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-05-31, $1m was out to 3 borrowers, 0.25% of net assets. The largest, CITIGROUP GLOBAL MARKETS INC., held 73.9% of it.

BorrowerOn loanShare of the loan
CITIGROUP GLOBAL MARKETS INC. $1m 73.9%
Wells Fargo Securities LLC $301,423 22.1%
JP MORGAN SECURITIES LLC $54,323 4.0%

Cash collateral reported against the loan: 0.25% of net assets, 101.1% 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 AGZ has filed, with each borrower: AGZ.json · all funds.

Since the previous filing

2026-02-28 → 2026-05-31

114 positions became 100: 7 added (11.3% of the fund at the later date), 21 dropped (22.3% at the earlier date). Half the sum of all weight changes, a turnover proxy: 23.7%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add. Every filing of AGZ compared this way, as a feed: changes.xml · all funds: filings received.
