Asset categories and pricing

as of 2026-06-30

99.92% debt, 0.07% short-term investment as filed; 0.1% 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 2026-06-30

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 $1.52B. Notional of an interest-rate or currency swap is not equity exposure.
