1Investments amounting to $296.3 million at June 30, 2026, and $274.8 million at December 31, 2025, were measured at fair value using the net asset value per share (or its practical expedient) and have not been classified in the fair value hierarchy. These investments are subject to restrictions on redemption, and the timing of liquidations of the underlying assets is unknown at each reporting period. The fair value amounts in this table are intended to permit reconciliation of the fair value hierarchy to total assets measured at fair value
