What stands out

as of 2026-05-31

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 $612M. Notional of an interest-rate or currency swap is not equity exposure.

Financing leg as filed: the fund pays Secured Overnight Financing Rate + 0% on $39M of long swap notional . Issuers fill the spread field differently (some file the all-in rate), so compare within an issuer, not across.
