This figure is not comparable with other funds

99.5% of net assets is derivative exposure, where position value and economic exposure are not the same quantity

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.

2026-02-28 → 2026-05-31

2 positions became 2: 0 added (0.0% of the fund at the later date), 0 dropped (0.0% at the earlier date). Half the sum of all weight changes, a turnover proxy: 0.0%. Positions are matched on identifiers, so a security whose identifier changed shows as one drop and one add.

Asset categories and pricing

as of 2026-05-31

99.49% derivative, 0.51% short-term investment as filed; 0.5% 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 $1.06B. Notional of an interest-rate or currency swap is not equity exposure.
