Returns the fund reported

Who borrows IVOG's shares
2026-05-31The 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.
| Borrower | On loan | Share 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 → 2026-05-31241 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%.

Asset categories and pricing
as of 2026-05-3199.51% 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 2026-05-31A 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.
| Swap counterparty | Notional | % of net assets |
|---|---|---|
| Bank of America NA | $5M | 0.25% |
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.
