Who borrows IVOG'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, $4m was out to 6 borrowers, 0.20% of net assets. The largest, CITIGROUP GLOBAL MARKETS INC., held 42.8% of it.

BorrowerOn loanShare of the loan
CITIGROUP GLOBAL MARKETS INC. $2m 42.8%
BARCLAYS BANK PLC $1m 31.8%
GOLDMAN SACHS & CO. $427,776 11.5%
Scotia Capital (USA) Inc $236,168 6.3%
BNP PARIBAS SECURITIES CORP $151,504 4.1%

Cash collateral reported against the loan: 0.21% of net assets, 103% 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 IVOG has filed, with each borrower: IVOG.json · all funds.

Since the previous filing

2026-02-28 → 2026-05-31

241 positions became 244: 8 added (3.8% of the fund at the later date), 5 dropped (7.4% at the earlier date). Half the sum of all weight changes, a turnover proxy: 13.8%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

99.51% 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 2026-05-31

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 $1.83B. Notional of an interest-rate or currency swap is not equity exposure.

Financing leg as filed: the fund pays OBFR01 + 0% on $5M of long swap notional . Issuers fill the spread field differently (some file the all-in rate), so compare within an issuer, not across.
