1.0% of VSDB is carried at a quoted market price (fair-value level 1); 0.1% at level 3, priced from the filer's own inputs. Categories and levels are the filer's, from Form N-PORT; 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 $896M. Notional of an interest-rate or currency swap is not equity exposure.
