Who borrows VOT's shares
2026-06-30The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2026-06-30, $142m was out to 16 borrowers, 0.41% of net assets. The largest, GOLDMAN SACHS & CO., held 22.8% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| GOLDMAN SACHS & CO. | $32m | 22.8% |
| JP MORGAN SECURITIES LLC | $24m | 17.1% |
| BARCLAYS BANK PLC | $14m | 9.8% |
| MORGAN STANLEY & CO LLC | $14m | 9.6% |
| CITIGROUP GLOBAL MARKETS INC. | $14m | 9.6% |
Cash collateral reported against the loan: 0.31% of net assets, 75.9% 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 VOT has filed, with each borrower: VOT.json · all funds.

2026-03-31 → 2026-06-30132 positions became 124: 6 added (3.1% of the fund at the later date), 14 dropped (4.9% at the earlier date). Half the sum of all weight changes, a turnover proxy: 15.5%.

Asset categories and pricing
as of 2026-06-3099.55% equity, 0.45% 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 2026-06-30A 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 $34.82B. Notional of an interest-rate or currency swap is not equity exposure.
| Swap counterparty | Notional | % of net assets |
|---|---|---|
| Bank of America NA | $27M | 0.08% |
Financing leg as filed: the fund pays OBFR01 + 0% on $27M of long swap notional . Issuers fill the spread field differently (some file the all-in rate), so compare within an issuer, not across.
