Measured concentration

The figure below is what the filing says, published unchanged. What it may not do is sit beside a plain long-only fund and be read as the same quantity. How comparability is decided.

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 $8.31B. Notional of an interest-rate or currency swap is not equity exposure.
| Swap counterparty | Notional | % of net assets |
|---|---|---|
| LCH Ltd | $1.70B | 20.42% |
| Goldman Sachs & Co. LLC | $462M | 5.56% |
| Intercontinental Exchange, Inc | $185M | 2.22% |
Financing leg as filed: the fund pays Euribor 3 Month + 0% on $549M of long swap notional . Issuers fill the spread field differently (some file the all-in rate), so compare within an issuer, not across.
