Derivative exposure and counterparties

as of 2026-06-30

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 $533M. Notional of an interest-rate or currency swap is not equity exposure.
