Returns the fund reported
2019-07 – 2026-06Monthly total returns from Item B.5 of IOO's own filings, 84 months on record. Not computed here and not from a price feed.
Cross-checked against a series computed separately from prices: median difference 0.10 percentage points over 84 months, which is roughly the distributions. Every month with the filing it came from: IOO.json · all funds.
Who borrows IOO's shares
2024-12-31The fund lends its holdings, and Item B.4.a of the filing names every firm holding them. At 2024-12-31, $37m was out to 2 borrowers, 0.57% of net assets. The largest, Wells Fargo Bank, National Association, held 93.1% of it.
| Borrower | On loan | Share of the loan |
|---|---|---|
| Wells Fargo Bank, National Association | $34m | 93.1% |
| MORGAN STANLEY & CO LLC | $3m | 6.9% |
Cash collateral reported against the loan: 0.60% of net assets, 104.7% 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 IOO has filed, with each borrower: IOO.json · all funds.
Since the previous filing
2026-03-31 → 2026-06-30111 positions became 113: 4 added (0.2% of the fund at the later date), 2 dropped (0.5% at the earlier date). Half the sum of all weight changes, a turnover proxy: 6.3%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

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 $8.47B. Notional of an interest-rate or currency swap is not equity exposure.
